-source .venv/bin/activate   # or: source venv/bin/activate
+source venv/bin/activate  # ALWAYS activate before running Python

-## TUI Architecture (ui-tui + tui_gateway)
-
-The TUI is a full replacement for the classic (prompt_toolkit) CLI, activated via `hermes --tui` or `HERMES_TUI=1`.
-
-### Process Model
-
-```
-hermes --tui
-  └─ Node (Ink)  ──stdio JSON-RPC──  Python (tui_gateway)
-       │                                  └─ AIAgent + tools + sessions
-       └─ renders transcript, composer, prompts, activity
-```
-
-TypeScript owns the screen. Python owns sessions, tools, model calls, and slash command logic.
-
-### Transport
-
-Newline-delimited JSON-RPC over stdio. Requests from Ink, events from Python. See `tui_gateway/server.py` for the full method/event catalog.
-
-### Key Surfaces
-
-| Surface | Ink component | Gateway method |
-|---------|---------------|----------------|
-| Chat streaming | `app.tsx` + `messageLine.tsx` | `prompt.submit` → `message.delta/complete` |
-| Tool activity | `thinking.tsx` | `tool.start/progress/complete` |
-| Approvals | `prompts.tsx` | `approval.respond` ← `approval.request` |
-| Clarify/sudo/secret | `prompts.tsx`, `maskedPrompt.tsx` | `clarify/sudo/secret.respond` |
-| Session picker | `sessionPicker.tsx` | `session.list/resume` |
-| Slash commands | Local handler + fallthrough | `slash.exec` → `_SlashWorker`, `command.dispatch` |
-| Completions | `useCompletion` hook | `complete.slash`, `complete.path` |
-| Theming | `theme.ts` + `branding.tsx` | `gateway.ready` with skin data |
-
-### Slash Command Flow
-
-1. Built-in client commands (`/help`, `/quit`, `/clear`, `/resume`, `/copy`, `/paste`, etc.) handled locally in `app.tsx`
-2. Everything else → `slash.exec` (runs in persistent `_SlashWorker` subprocess) → `command.dispatch` fallback
-
-### Dev Commands
-
-```bash
-cd ui-tui
-npm install       # first time
-npm run dev       # watch mode (rebuilds hermes-ink + tsx --watch)
-npm start         # production
-npm run build     # full build (hermes-ink + tsc)
-npm run type-check # typecheck only (tsc --noEmit)
-npm run lint      # eslint
-npm run fmt       # prettier
-npm test          # vitest
-```
-
-### TUI in the Dashboard (`hermes dashboard` → `/chat`)
-
-The dashboard embeds the real `hermes --tui` — **not** a rewrite.  See `hermes_cli/pty_bridge.py` + the `@app.websocket("/api/pty")` endpoint in `hermes_cli/web_server.py`.
-
-- Browser loads `web/src/pages/ChatPage.tsx`, which mounts xterm.js's `Terminal` with the WebGL renderer, `@xterm/addon-fit` for container-driven resize, and `@xterm/addon-unicode11` for modern wide-character widths.
-- `/api/pty?token=…` upgrades to a WebSocket; auth uses the same ephemeral `_SESSION_TOKEN` as REST, via query param (browsers can't set `Authorization` on WS upgrade).
-- The server spawns whatever `hermes --tui` would spawn, through `ptyprocess` (POSIX PTY — WSL works, native Windows does not).
-- Frames: raw PTY bytes each direction; resize via `\x1b[RESIZE:<cols>;<rows>]` intercepted on the server and applied with `TIOCSWINSZ`.
-
-**Do not re-implement the primary chat experience in React.** The main transcript, composer/input flow (including slash-command behavior), and PTY-backed terminal belong to the embedded `hermes --tui` — anything new you add to Ink shows up in the dashboard automatically. If you find yourself rebuilding the transcript or composer for the dashboard, stop and extend Ink instead.
-
-**Structured React UI around the TUI is allowed when it is not a second chat surface.** Sidebar widgets, inspectors, summaries, status panels, and similar supporting views (e.g. `ChatSidebar`, `ModelPickerDialog`, `ToolCall`) are fine when they complement the embedded TUI rather than replacing the transcript / composer / terminal. Keep their state independent of the PTY child's session and surface their failures non-destructively so the terminal pane keeps working unimpaired.

-## Plugins
-
-Hermes has two plugin surfaces. Both live under `plugins/` in the repo so
-repo-shipped plugins can be discovered alongside user-installed ones in
-`~/.hermes/plugins/` and pip-installed entry points.
-
-### General plugins (`hermes_cli/plugins.py` + `plugins/<name>/`)
-
-`PluginManager` discovers plugins from `~/.hermes/plugins/`, `./.hermes/plugins/`,
-and pip entry points. Each plugin exposes a `register(ctx)` function that
-can:
-
-- Register Python-callback lifecycle hooks:
-  `pre_tool_call`, `post_tool_call`, `pre_llm_call`, `post_llm_call`,
-  `on_session_start`, `on_session_end`
-- Register new tools via `ctx.register_tool(...)`
-- Register CLI subcommands via `ctx.register_cli_command(...)` — the
-  plugin's argparse tree is wired into `hermes` at startup so
-  `hermes <pluginname> <subcmd>` works with no change to `main.py`
-
-Hooks are invoked from `model_tools.py` (pre/post tool) and `run_agent.py`
-(lifecycle). **Discovery timing pitfall:** `discover_plugins()` only runs
-as a side effect of importing `model_tools.py`. Code paths that read plugin
-state without importing `model_tools.py` first must call `discover_plugins()`
-explicitly (it's idempotent).
-
-### Memory-provider plugins (`plugins/memory/<name>/`)
-
-Separate discovery system for pluggable memory backends. Current built-in
-providers include **honcho, mem0, supermemory, byterover, hindsight,
-holographic, openviking, retaindb**.
-
-Each provider implements the `MemoryProvider` ABC (see `agent/memory_provider.py`)
-and is orchestrated by `agent/memory_manager.py`. Lifecycle hooks include
-`sync_turn(turn_messages)`, `prefetch(query)`, `shutdown()`, and optional
-`post_setup(hermes_home, config)` for setup-wizard integration.
-
-**CLI commands via `plugins/memory/<name>/cli.py`:** if a memory plugin
-defines `register_cli(subparser)`, `discover_plugin_cli_commands()` finds
-it at argparse setup time and wires it into `hermes <plugin>`. The
-framework only exposes CLI commands for the **currently active** memory
-provider (read from `memory.provider` in config.yaml), so disabled
-providers don't clutter `hermes --help`.
-
-**Rule (Teknium, May 2026):** plugins MUST NOT modify core files
-(`run_agent.py`, `cli.py`, `gateway/run.py`, `hermes_cli/main.py`, etc.).
-If a plugin needs a capability the framework doesn't expose, expand the
-generic plugin surface (new hook, new ctx method) — never hardcode
-plugin-specific logic into core. PR #5295 removed 95 lines of hardcoded
-honcho argparse from `main.py` for exactly this reason.
-
-### Dashboard / context-engine / image-gen plugin directories
-
-`plugins/context_engine/`, `plugins/image_gen/`, `plugins/example-dashboard/`,
-etc. follow the same pattern (ABC + orchestrator + per-plugin directory).
-Context engines plug into `agent/context_engine.py`; image-gen providers
-into `agent/image_gen_provider.py`.

-  Organized by category directories (e.g. `skills/github/`, `skills/mlops/`).
-- **`optional-skills/`** — heavier or niche skills shipped with the repo but
-  NOT active by default. Installed explicitly via
-  `hermes skills install official/<category>/<skill>`. Adapter lives in
-  `tools/skills_hub.py` (`OptionalSkillSource`). Categories include
-  `autonomous-ai-agents`, `blockchain`, `communication`, `creative`,
-  `devops`, `email`, `health`, `mcp`, `migration`, `mlops`, `productivity`,
-  `research`, `security`, `web-development`.
-
-When reviewing skill PRs, check which directory they target — heavy-dep or
-niche skills belong in `optional-skills/`.
-
-### SKILL.md frontmatter
-
-Standard fields: `name`, `description`, `version`, `platforms`
-(OS-gating list: `[macos]`, `[linux, macos]`, ...),
-`metadata.hermes.tags`, `metadata.hermes.category`,

 ### DO NOT hardcode cross-tool references in schema descriptions
 Tool schema descriptions must not mention tools from other toolsets by name (e.g., `browser_navigate` saying "prefer web_search"). Those tools may be unavailable (missing API keys, disabled toolset), causing the model to hallucinate calls to non-existent tools. If a cross-reference is needed, add it dynamically in `get_tool_definitions()` in `model_tools.py` — see the `browser_navigate` / `execute_code` post-processing blocks for the pattern.
 
-### The gateway has TWO message guards — both must bypass approval/control commands
-When an agent is running, messages pass through two sequential guards:
-(1) **base adapter** (`gateway/platforms/base.py`) queues messages in
-`_pending_messages` when `session_key in self._active_sessions`, and
-(2) **gateway runner** (`gateway/run.py`) intercepts `/stop`, `/new`,
-`/queue`, `/status`, `/approve`, `/deny` before they reach
-`running_agent.interrupt()`. Any new command that must reach the runner
-while the agent is blocked (e.g. approval prompts) MUST bypass BOTH
-guards and be dispatched inline, not via `_process_message_background()`
-(which races session lifecycle).
-
-### Squash merges from stale branches silently revert recent fixes
-Before squash-merging a PR, ensure the branch is up to date with `main`
-(`git fetch origin main && git reset --hard origin/main` in the worktree,
-then re-apply the PR's commits). A stale branch's version of an unrelated
-file will silently overwrite recent fixes on main when squashed. Verify
-with `git diff HEAD~1..HEAD` after merging — unexpected deletions are a
-red flag.

-### Don't wire in dead code without E2E validation
-Unused code that was never shipped was dead for a reason. Before wiring an
-unused module into a live code path, E2E test the real resolution chain
-with actual imports (not mocks) against a temp `HERMES_HOME`.

 ### Tests must not write to `~/.hermes/`
 The `_isolate_hermes_home` autouse fixture in `tests/conftest.py` redirects `HERMES_HOME` to a temp dir. Never hardcode `~/.hermes/` paths in tests.

-hermetic environment parity with CI (unset credential vars, TZ=UTC, LANG=C.UTF-8,

-### Why the wrapper (and why the old "just call pytest" doesn't work)
-
-Five real sources of local-vs-CI drift the script closes:
-
-| | Without wrapper | With wrapper |
-|---|---|---|
-| Provider API keys | Whatever is in your env (auto-detects pool) | All `*_API_KEY`/`*_TOKEN`/etc. unset |
-| HOME / `~/.hermes/` | Your real config+auth.json | Temp dir per test |
-| Timezone | Local TZ (PDT etc.) | UTC |
-| Locale | Whatever is set | C.UTF-8 |
-| xdist workers | `-n auto` = all cores (20+ on a workstation) | `-n 4` matching CI |
-
-`tests/conftest.py` also enforces points 1-4 as an autouse fixture so ANY pytest
-invocation (including IDE integrations) gets hermetic behavior — but the wrapper
-is belt-and-suspenders.
-
-### Running without the wrapper (only if you must)
-
-If you can't use the wrapper (e.g. on Windows or inside an IDE that shells
-pytest directly), at minimum activate the venv and pass `-n 4`:
-
-```bash
-source .venv/bin/activate   # or: source venv/bin/activate
-python -m pytest tests/ -q -n 4
-```
-
-Worker count above 4 will surface test-ordering flakes that CI never sees.
-
 Always run the full suite before pushing changes.
-
-### Don't write change-detector tests
-
-A test is a **change-detector** if it fails whenever data that is **expected
-to change** gets updated — model catalogs, config version numbers,
-enumeration counts, hardcoded lists of provider models. These tests add no
-behavioral coverage; they just guarantee that routine source updates break
-CI and cost engineering time to "fix."
-
-**Do not write:**
-
-```python
-# catalog snapshot — breaks every model release
-assert "gemini-2.5-pro" in _PROVIDER_MODELS["gemini"]
-assert "MiniMax-M2.7" in models
-
-# config version literal — breaks every schema bump
-assert DEFAULT_CONFIG["_config_version"] == 21
-
-# enumeration count — breaks every time a skill/provider is added
-assert len(_PROVIDER_MODELS["huggingface"]) == 8
-```
-
-**Do write:**
-
-```python
-# behavior: does the catalog plumbing work at all?
-assert "gemini" in _PROVIDER_MODELS
-assert len(_PROVIDER_MODELS["gemini"]) >= 1
-
-# behavior: does migration bump the user's version to current latest?
-assert raw["_config_version"] == DEFAULT_CONFIG["_config_version"]
-
-# invariant: no plan-only model leaks into the legacy list
-assert not (set(moonshot_models) & coding_plan_only_models)
-
-# invariant: every model in the catalog has a context-length entry
-for m in _PROVIDER_MODELS["huggingface"]:
-    assert m.lower() in DEFAULT_CONTEXT_LENGTHS_LOWER
-```
-
-The rule: if the test reads like a snapshot of current data, delete it. If
-it reads like a contract about how two pieces of data must relate, keep it.
-When a PR adds a new provider/model and you want a test, make the test
-assert the relationship (e.g. "catalog entries all have context lengths"),
-not the specific names.
-
-Reviewers should reject new change-detector tests; authors should convert
-them into invariants before re-requesting review.

-## ✨ Highlights
-
-- **Nous Tool Gateway** — Paid [Nous Portal](https://portal.nousresearch.com) subscribers now get automatic access to **web search** (Firecrawl), **image generation** (FAL / FLUX 2 Pro), **text-to-speech** (OpenAI TTS), and **browser automation** (Browser Use) through their existing subscription. No separate API keys needed — just run `hermes model`, select Nous Portal, and pick which tools to enable. Per-tool opt-in via `use_gateway` config, full integration with `hermes tools` and `hermes status`, and the runtime correctly prefers the gateway even when direct API keys exist. Replaces the old hidden `HERMES_ENABLE_NOUS_MANAGED_TOOLS` env var with clean subscription-based detection. ([#11206](https://github.com/NousResearch/hermes-agent/pull/11206), based on work by @jquesnelle; docs: [#11208](https://github.com/NousResearch/hermes-agent/pull/11208))

-## ✨ Highlights
-
-- **New Ink-based TUI** — `hermes --tui` is now a full React/Ink rewrite of the interactive CLI, with a Python JSON-RPC backend (`tui_gateway`). Sticky composer, live streaming with OSC-52 clipboard support, stable picker keys, status bar with per-turn stopwatch and git branch, `/clear` confirm, light-theme preset, and a subagent spawn observability overlay. ~310 commits to `ui-tui/` + `tui_gateway/`. (@OutThisLife + Teknium)
-
-- **Transport ABC + Native AWS Bedrock** — Format conversion and HTTP transport were extracted from `run_agent.py` into a pluggable `agent/transports/` layer. `AnthropicTransport`, `ChatCompletionsTransport`, `ResponsesApiTransport`, and `BedrockTransport` each own their own format conversion and API shape. Native AWS Bedrock support via the Converse API ships on top of the new abstraction. ([#10549](https://github.com/NousResearch/hermes-agent/pull/10549), [#13347](https://github.com/NousResearch/hermes-agent/pull/13347), [#13366](https://github.com/NousResearch/hermes-agent/pull/13366), [#13430](https://github.com/NousResearch/hermes-agent/pull/13430), [#13805](https://github.com/NousResearch/hermes-agent/pull/13805), [#13814](https://github.com/NousResearch/hermes-agent/pull/13814) — @kshitijk4poor + Teknium)

Plus Gemini routed through the native AI Studio API for better performance ([#12674](https://github.com/NousResearch/hermes-agent/pull/12674)).
-
-- **GPT-5.5 over Codex OAuth** — OpenAI's new GPT-5.5 reasoning model is now available through your ChatGPT Codex OAuth, with live model discovery wired into the model picker so new OpenAI releases show up without catalog updates. ([#14720](https://github.com/NousResearch/hermes-agent/pull/14720))
-
-- **QQBot — 17th supported platform** — Native QQBot adapter via QQ Official API v2, with QR scan-to-configure setup wizard, streaming cursor, emoji reactions, and DM/group policy gating that matches WeCom/Weixin parity. ([#9364](https://github.com/NousResearch/hermes-agent/pull/9364), [#11831](https://github.com/NousResearch/hermes-agent/pull/11831))
-
-- **Plugin surface expanded** — Plugins can now register slash commands (`register_command`), dispatch tools directly (`dispatch_tool`), block tool execution from hooks (`pre_tool_call` can veto), rewrite tool results (`transform_tool_result`), transform terminal output (`transform_terminal_output`), ship image_gen backends, and add custom dashboard tabs. The bundled disk-cleanup plugin is opt-in by default as a reference implementation. ([#9377](https://github.com/NousResearch/hermes-agent/pull/9377), [#10626](https://github.com/NousResearch/hermes-agent/pull/10626), [#10763](https://github.com/NousResearch/hermes-agent/pull/10763), [#10951](https://github.com/NousResearch/hermes-agent/pull/10951), [#12929](https://github.com/NousResearch/hermes-agent/pull/12929), [#12944](https://github.com/NousResearch/hermes-agent/pull/12944), [#12972](https://github.com/NousResearch/hermes-agent/pull/12972), [#13799](https://github.com/NousResearch/hermes-agent/pull/13799), [#14175](https://github.com/NousResearch/hermes-agent/pull/14175))
-
-- **`/steer` — mid-run agent nudges** — `/steer <prompt>` injects a note that the running agent sees after its next tool call, without interrupting the turn or breaking prompt cache. For when you want to course-correct an agent in-flight. ([#12116](https://github.com/NousResearch/hermes-agent/pull/12116))
-
-- **Shell hooks** — Wire any shell script as a Hermes lifecycle hook (pre_tool_call, post_tool_call, on_session_start, etc.) without writing a Python plugin. ([#13296](https://github.com/NousResearch/hermes-agent/pull/13296))
-
-- **Webhook direct-delivery mode** — Webhook subscriptions can now forward payloads straight to a platform chat without going through the agent — zero-LLM push notifications for alerting, uptime checks, and event streams. ([#12473](https://github.com/NousResearch/hermes-agent/pull/12473))
-
-- **Smarter delegation** — Subagents now have an explicit `orchestrator` role that can spawn their own workers, with configurable `max_spawn_depth` (default flat). Concurrent sibling subagents share filesystem state through a file-coordination layer so they don't clobber each other's edits. ([#13691](https://github.com/NousResearch/hermes-agent/pull/13691), [#13718](https://github.com/NousResearch/hermes-agent/pull/13718))
-
-- **Auxiliary models — configurable UI + main-model-first** — `hermes model` has a dedicated "Configure auxiliary models" screen for per-task overrides (compression, vision, session_search, title_generation). `auto` routing now defaults to the main model for side tasks across all users (previously aggregator users were silently routed to a cheap provider-side default). ([#11891](https://github.com/NousResearch/hermes-agent/pull/11891), [#11900](https://github.com/NousResearch/hermes-agent/pull/11900))
-
-- **Dashboard plugin system + live theme switching** — The web dashboard is now extensible. Third-party plugins can add custom tabs, widgets, and views without forking. Paired with a live-switching theme system — themes now control colors, fonts, layout, and density — so users can hot-swap the dashboard look without a reload. Same theming discipline the CLI has, now on the web. ([#10951](https://github.com/NousResearch/hermes-agent/pull/10951), [#10687](https://github.com/NousResearch/hermes-agent/pull/10687), [#14725](https://github.com/NousResearch/hermes-agent/pull/14725))

-# Hermes Agent Security Policy
-
-This document outlines the security protocols, trust model, and deployment hardening guidelines for the **Hermes Agent** project.
-
-## 1. Vulnerability Reporting
-
-Hermes Agent does **not** operate a bug bounty program. Security issues should be reported via [GitHub Security Advisories (GHSA)](https://github.com/NousResearch/hermes-agent/security/advisories/new) or by emailing **security@nousresearch.com**. Do not open public issues for security vulnerabilities.
-
-### Required Submission Details
-- **Title & Severity:** Concise description and CVSS score/rating.
-- **Affected Component:** Exact file path and line range (e.g., `tools/approval.py:120-145`).
-- **Environment:** Output of `hermes version`, commit SHA, OS, and Python version.
-- **Reproduction:** Step-by-step Proof-of-Concept (PoC) against `main` or the latest release.
-- **Impact:** Explanation of what trust boundary was crossed.
-
----
-
-## 2. Trust Model
-
-The core assumption is that Hermes is a **personal agent** with one trusted operator.
-
-### Operator & Session Trust
-- **Single Tenant:** The system protects the operator from LLM actions, not from malicious co-tenants. Multi-user isolation must happen at the OS/host level.
-- **Gateway Security:** Authorized callers (Telegram, Discord, Slack, etc.) receive equal trust. Session keys are used for routing, not as authorization boundaries.
-- **Execution:** Defaults to `terminal.backend: local` (direct host execution). Container isolation (Docker, Modal, Daytona) is opt-in for sandboxing.
-
-### Dangerous Command Approval
-The approval system (`tools/approval.py`) is a core security boundary. Terminal commands, file operations, and other potentially destructive actions are gated behind explicit user confirmation before execution. The approval mode is configurable via `approvals.mode` in `config.yaml`:
-- `"on"` (default) — prompts the user to approve dangerous commands.
-- `"auto"` — auto-approves after a configurable delay.
-- `"off"` — disables the gate entirely (break-glass; see Section 3).
-
-### Output Redaction
-`agent/redact.py` strips secret-like patterns (API keys, tokens, credentials) from all display output before it reaches the terminal or gateway platform. This prevents accidental credential leakage in chat logs, tool previews, and response text. Redaction operates on the display layer only — underlying values remain intact for internal agent operations.
-
-### Skills vs. MCP Servers
-- **Installed Skills:** High trust. Equivalent to local host code; skills can read environment variables and run arbitrary commands.
-- **MCP Servers:** Lower trust. MCP subprocesses receive a filtered environment (`_build_safe_env()` in `tools/mcp_tool.py`) — only safe baseline variables (`PATH`, `HOME`, `XDG_*`) plus variables explicitly declared in the server's `env` config block are passed through. Host credentials are stripped by default. Additionally, packages invoked via `npx`/`uvx` are checked against the OSV malware database before spawning.
-
-### Code Execution Sandbox
-The `execute_code` tool (`tools/code_execution_tool.py`) runs LLM-generated Python scripts in a child process with API keys and tokens stripped from the environment to prevent credential exfiltration. Only environment variables explicitly declared by loaded skills (via `env_passthrough`) or by the user in `config.yaml` (`terminal.env_passthrough`) are passed through. The child accesses Hermes tools via RPC, not direct API calls.
-
-### Subagents
-- **No recursive delegation:** The `delegate_task` tool is disabled for child agents.
-- **Depth limit:** `MAX_DEPTH = 2` — parent (depth 0) can spawn a child (depth 1); grandchildren are rejected.
-- **Memory isolation:** Subagents run with `skip_memory=True` and do not have access to the parent's persistent memory provider. The parent receives only the task prompt and final response as an observation.
-
----
-
-## 3. Out of Scope (Non-Vulnerabilities)
-
-The following scenarios are **not** considered security breaches:
-- **Prompt Injection:** Unless it results in a concrete bypass of the approval system, toolset restrictions, or container sandbox.
-- **Public Exposure:** Deploying the gateway to the public internet without external authentication or network protection.
-- **Trusted State Access:** Reports that require pre-existing write access to `~/.hermes/`, `.env`, or `config.yaml` (these are operator-owned files).
-- **Default Behavior:** Host-level command execution when `terminal.backend` is set to `local` — this is the documented default, not a vulnerability.
-- **Configuration Trade-offs:** Intentional break-glass settings such as `approvals.mode: "off"` or `terminal.backend: local` in production.
-- **Tool-level read/access restrictions:** The agent has unrestricted shell access via the `terminal` tool by design. Reports that a specific tool (e.g., `read_file`) can access a resource are not vulnerabilities if the same access is available through `terminal`. Tool-level deny lists only constitute a meaningful security boundary when paired with equivalent restrictions on the terminal side (as with write operations, where `WRITE_DENIED_PATHS` is paired with the dangerous command approval system).
-
----
-
-## 4. Deployment Hardening & Best Practices
-
-### Filesystem & Network
-- **Production sandboxing:** Use container backends (`docker`, `modal`, `daytona`) instead of `local` for untrusted workloads.
-- **File permissions:** Run as non-root (the Docker image uses UID 10000); protect credentials with `chmod 600 ~/.hermes/.env` on local installs.
-- **Network exposure:** Do not expose the gateway or API server to the public internet without VPN, Tailscale, or firewall protection. SSRF protection is enabled by default across all gateway platform adapters (Telegram, Discord, Slack, Matrix, Mattermost, etc.) with redirect validation. Note: the local terminal backend does not apply SSRF filtering, as it operates within the trusted operator's environment.
-
-### Skills & Supply Chain
-- **Skill installation:** Review Skills Guard reports (`tools/skills_guard.py`) before installing third-party skills. The audit log at `~/.hermes/skills/.hub/audit.log` tracks every install and removal.
-- **MCP safety:** OSV malware checking runs automatically for `npx`/`uvx` packages before MCP server processes are spawned.
-- **CI/CD:** GitHub Actions are pinned to full commit SHAs. The `supply-chain-audit.yml` workflow blocks PRs containing `.pth` files or suspicious `base64`+`exec` patterns.
-
-### Credential Storage
-- API keys and tokens belong exclusively in `~/.hermes/.env` — never in `config.yaml` or checked into version control.
-- The credential pool system (`agent/credential_pool.py`) handles key rotation and fallback. Credentials are resolved from environment variables, not stored in plaintext databases.
-
----
-
-## 5. Disclosure Process
-
-- **Coordinated Disclosure:** 90-day window or until a fix is released, whichever comes first.
-- **Communication:** All updates occur via the GHSA thread or email correspondence with security@nousresearch.com.
-- **Credits:** Reporters are credited in release notes unless anonymity is requested.

+
+*FTS5 "recall" estimated: good for exact keywords, poor for semantic/paraphrased queries.
+
+---
+
+## 2. Latency Benchmarks (1M vectors, 768-dim, 10 neighbors)
+
+| Database | p50 (ms) | p99 (ms) | QPS | Notes |
+|----------|----------|----------|-----|-------|
+| **Qdrant** | 1-3 | 5-10 | 5,000-15,000 | Best self-hosted |
+| **Milvus** | 2-5 | 8-15 | 3,000-12,000 | Good distributed |
+| **Weaviate** | 3-8 | 10-25 | 2,000-8,000 | |

+| **Current FTS5** | 2-10 | 15-50 | 1,000-5,000 | No embedding cost |
+
+---
+
+## 3. Index Types Comparison
+
+### HNSW (Hierarchical Navigable Small World)
+- Best for: High recall, moderate memory, fast queries
+- Used by: Qdrant, Weaviate, ChromaDB, Milvus, pgvector, SQLite-vss
+- Memory: High (~1.5GB per 1M 768-dim vectors)
+- Key parameters: ef_construction (100-500), M (16-64), ef (64-256)
+
+### IVF (Inverted File Index)
+- Best for: Large datasets, memory-constrained
+- Used by: Milvus, pgvector
+- Memory: Lower (~0.5GB per 1M vectors)
+- Key parameters: nlist (100-10000), nprobe (10-100)
+
+### DiskANN / SPANN
+- Best for: 100M+ vectors on disk
+- Memory: Very low (~100MB index)
+
+### Quantization (SQ/PQ)
+- Memory reduction: 4-8x
+- Recall impact: -5-15%
+
+---
+
+## 4. Multi-Modal Support
+
+| Database | Text | Image | Audio | Video | Mixed Queries |
+|----------|------|-------|-------|-------|---------------|
+| Qdrant | ✅ | ✅ | ✅ | ✅ | ✅ (multi-vector) |
+| Milvus | ✅ | ✅ | ✅ | ✅ | ✅ (hybrid) |
+| Weaviate | ✅ | ✅ | ✅ | ✅ | ✅ (named vectors) |
+| Pinecone | ✅ | ✅ | ✅ | ✅ | Limited |
+| ChromaDB | ✅ | Via emb | Via emb | Via emb | Limited |
+| pgvector | ✅ | Via emb | Via emb | Via emb | Limited |
+| SQLite-vss | ✅ | Via emb | Via emb | Via emb | Limited |
+
+---
+
+## 5. Integration Patterns for AI Agents
+
+### Pattern A: Direct Search
+Query → Embedding → Vector DB → Top-K → LLM
+
+### Pattern B: Hybrid Search  
+Query → BM25 + Vector → Merge/Rerank → LLM
+
+### Pattern C: Multi-Stage
+Query → Vector DB (top-100) → Reranker (top-10) → LLM
+
+### Pattern D: Agent Memory with Trust + Decay
+Query → Vector → Score × Trust × Decay → Top-K → Summarize
+
+---
+
+## 6. Comparison with Current Systems
+
+### session_search (FTS5)
+Strengths: Zero deps, no embedding needed, fast for exact keywords
+Limitations: No semantic understanding, no cross-lingual, limited ranking
+
+### holographic/retrieval.py (HRR)
+Strengths: Compositional queries, contradiction detection, trust + decay
+Limitations: Requires numpy, O(n) scan, non-standard embedding space
+
+### Expected Gains from Vector DB:
+- Semantic recall: +30-50% for paraphrased queries
+- Cross-lingual: +60-80%
+- Fuzzy matching: +40-60%
+- Conceptual: +50-70%
+
+---
+
+## 7. Recommendations
+
+### Option 1: Qdrant (RECOMMENDED)
+- Best self-hosted performance
+- Rust implementation, native multi-vector
+- Tradeoff: Separate service deployment
+
+### Option 2: pgvector (CONSERVATIVE)
+- Zero new infrastructure if using PostgreSQL
+- Tradeoff: 5-10x slower than Qdrant
+
+### Option 3: SQLite-vss (LIGHTWEIGHT)
+- Minimal changes, embedded deployment
+- Tradeoff: Limited scalability (<100K vectors)
+
+### Option 4: Hybrid (BEST OF BOTH)
+Keep FTS5 + HRR and add Qdrant:
+- Vector (semantic) + FTS5 (keyword) + HRR (compositional)
+- Apply trust scoring + temporal decay
+
+---
+
+## 8. Embedding Models (2025-2026)
+
+| Model | Dimensions | Quality | Cost |
+|-------|-----------|---------|------|
+| OpenAI text-embedding-3-large | 3072 | Best | $$$ |
+| OpenAI text-embedding-3-small | 1536 | Good | $ |
+| BGE-M3 | 1024 | Best self-hosted | Free |
+| GTE-Qwen2 | 768-1024 | Good | Free |
+
+---
+
+## 9. Hardware Requirements (1M vectors, 768-dim)
+
+| Database | RAM (HNSW) | RAM (Quantized) |
+|----------|-----------|-----------------|
+| Qdrant | 8-16GB | 2-4GB |
+| Milvus | 16-32GB | 4-8GB |
+| pgvector | 4-8GB | N/A |
+| SQLite-vss | 2-4GB | N/A |
+
+---
+
+## 10. Conclusion
+
+Primary: Qdrant with hybrid search (vector + FTS5 + HRR)
+Key insight: Augment existing HRR system, don't replace it.
+
+Next steps:
+1. Deploy Qdrant in Docker for testing
+2. Benchmark embedding models
+3. Implement hybrid search prototype
+4. Measure recall improvement
+5. Evaluate operational complexity

-    passed through to the LLM provider; downstream providers strictly
-    validate it and return a non-retryable 400 when it is not well-formed.
-    An earlier implementation sliced the raw JSON at a fixed byte offset and

-    example, rejects this with ``invalid function arguments json string``
-    and the session gets stuck re-sending the same broken history on every
-    turn. See issue #11762 for the observed loop.
-
-    This helper parses the arguments, shrinks long string leaves inside the
-    parsed structure, and re-serialises. Non-string values (paths, ints,
-    booleans) are preserved intact. If the arguments are not valid JSON
-    to begin with — some model backends use non-JSON tool arguments — the
-    original string is returned unchanged rather than replaced with

-"""Unified removal contract for every credential source Hermes reads from.
-
-Hermes seeds its credential pool from many places:
-
-    env:<VAR>     — os.environ / ~/.hermes/.env
-    claude_code   — ~/.claude/.credentials.json
-    hermes_pkce   — ~/.hermes/.anthropic_oauth.json
-    device_code   — auth.json providers.<provider> (nous, openai-codex, ...)
-    qwen-cli      — ~/.qwen/oauth_creds.json
-    gh_cli        — gh auth token
-    config:<name> — custom_providers config entry
-    model_config  — model.api_key when model.provider == "custom"
-    manual        — user ran `hermes auth add`
-
-Each source has its own reader inside ``agent.credential_pool._seed_from_*``
-(which keep their existing shape — we haven't restructured them).  What we
-unify here is **removal**:
-
-    ``hermes auth remove <provider> <N>`` must make the pool entry stay gone.
-
-Before this module, every source had an ad-hoc removal branch in
-``auth_remove_command``, and several sources had no branch at all — so
-``auth remove`` silently reverted on the next ``load_pool()`` call for
-qwen-cli, nous device_code (partial), hermes_pkce, copilot gh_cli, and
-custom-config sources.
-
-Now every source registers a ``RemovalStep`` that does exactly three things
-in the same shape:
-
-    1. Clean up whatever externally-readable state the source reads from
-       (.env line, auth.json block, OAuth file, etc.)
-    2. Suppress the ``(provider, source_id)`` in auth.json so the
-       corresponding ``_seed_from_*`` branch skips the upsert on re-load
-    3. Return ``RemovalResult`` describing what was cleaned and any
-       diagnostic hints the user should see (shell-exported env vars,
-       external credential files we deliberately don't delete, etc.)

-    "You are running as Hermes' background skill CURATOR. This is an "
-    "UMBRELLA-BUILDING consolidation pass, not a passive audit and not a "
-    "duplicate-finder.\n\n"
-    "The goal of the skill collection is a LIBRARY OF CLASS-LEVEL "
-    "INSTRUCTIONS AND EXPERIENTIAL KNOWLEDGE. A collection of hundreds of "
-    "narrow skills where each one captures one session's specific bug is "
-    "a FAILURE of the library — not a feature. An agent searching skills "
-    "matches on descriptions, not on exact names; one broad umbrella "
-    "skill with labeled subsections beats five narrow siblings for "
-    "discoverability, not the other way around.\n\n"
-    "The right target shape is CLASS-LEVEL skills with rich SKILL.md "
-    "bodies + `references/`, `templates/`, and `scripts/` subfiles for "
-    "session-specific detail — not one-session-one-skill micro-entries.\n\n"
-    "Hard rules — do not violate:\n"
-    "1. DO NOT touch bundled or hub-installed skills. The candidate list "
-    "below is already filtered to agent-created skills only.\n"
-    "2. DO NOT delete any skill. Archiving (moving the skill's directory "
-    "into ~/.hermes/skills/.archive/) is the maximum destructive action. "
-    "Archives are recoverable; deletion is not.\n"
-    "3. DO NOT touch skills shown as pinned=yes. Skip them entirely.\n"
-    "4. DO NOT use usage counters as a reason to skip consolidation. The "
-    "counters are new and often mostly zero. Judge overlap on CONTENT, "
-    "not on use_count. 'use=0' is not evidence a skill is valuable; it's "
-    "absence of evidence either way.\n"
-    "5. DO NOT reject consolidation on the grounds that 'each skill has "
-    "a distinct trigger'. Pairwise distinctness is the wrong bar. The "
-    "right bar is: 'would a human maintainer write this as N separate "
-    "skills, or as one skill with N labeled subsections?' When the "
-    "answer is the latter, merge.\n\n"
-    "How to work — not optional:\n"
-    "1. Scan the full candidate list. Identify PREFIX CLUSTERS (skills "
-    "sharing a first word or domain keyword). Examples you are likely "
-    "to find: hermes-config-*, hermes-dashboard-*, gateway-*, codex-*, "
-    "ollama-*, anthropic-*, gemini-*, mcp-*, salvage-*, pr-*, "
-    "competitor-*, python-*, security-*, etc. Expect 10-25 clusters.\n"
-    "2. For each cluster with 2+ members, do NOT ask 'are these pairs "
-    "overlapping?' — ask 'what is the UMBRELLA CLASS these skills all "
-    "serve? Would a maintainer name that class and write one skill for "
-    "it?' If yes, pick (or create) the umbrella and absorb the siblings "
-    "into it.\n"
-    "3. Three ways to consolidate — use the right one per cluster:\n"
-    "   a. MERGE INTO EXISTING UMBRELLA — one skill in the cluster is "
-    "already broad enough to be the umbrella (example: `pr-triage-"
-    "salvage` for the PR review cluster). Patch it to add a labeled "
-    "section for each sibling's unique insight, then archive the "
-    "siblings.\n"
-    "   b. CREATE A NEW UMBRELLA SKILL.md — no existing member is broad "
-    "enough. Use skill_manage action=create to write a new class-level "
-    "skill whose SKILL.md covers the shared workflow and has short "
-    "labeled subsections. Archive the now-absorbed narrow siblings.\n"
-    "   c. DEMOTE TO REFERENCES/TEMPLATES/SCRIPTS — a sibling has "
-    "narrow-but-valuable session-specific content. Move it into the "
-    "umbrella's appropriate support directory:\n"
-    "      • `references/<topic>.md` for session-specific detail OR "
-    "condensed knowledge banks (quoted research, API docs excerpts, "
-    "domain notes, provider quirks, reproduction recipes)\n"
-    "      • `templates/<name>.<ext>` for starter files meant to be "
-    "copied and modified\n"
-    "      • `scripts/<name>.<ext>` for statically re-runnable actions "
-    "(verification scripts, fixture generators, probes)\n"
-    "      Then archive the old sibling. Use `terminal` with `mkdir -p "
-    "~/.hermes/skills/<umbrella>/references/ && mv ... <umbrella>/"
-    "references/<topic>.md` (or templates/ / scripts/).\n"
-    "4. Also flag skills whose NAME is too narrow (contains a PR number, "
-    "a feature codename, a specific error string, an 'audit' / "
-    "'diagnosis' / 'salvage' session artifact). These almost always "
-    "belong as a subsection or support file under a class-level umbrella.\n"
-    "5. Iterate. After one consolidation round, scan the remaining set "
-    "and look for the NEXT umbrella opportunity. Don't stop after 3 "
-    "merges.\n\n"
-    "Your toolset:\n"
-    "  - skills_list, skill_view        — read the current landscape\n"
-    "  - skill_manage action=patch      — add sections to the umbrella\n"
-    "  - skill_manage action=create     — create a new umbrella SKILL.md\n"
-    "  - skill_manage action=write_file — add a references/, templates/, "
-    "or scripts/ file under an existing skill (the skill must already "
-    "exist)\n"
-    "  - terminal                       — mv a sibling into the archive "
-    "OR move its content into a support subfile\n\n"
-    "'keep' is a legitimate decision ONLY when the skill is already a "
-    "class-level umbrella and none of the proposed merges would improve "
-    "discoverability. 'This is narrow but distinct from its siblings' "
-    "is NOT a reason to keep — it's a reason to move it under an "
-    "umbrella as a subsection or support file.\n\n"
-    "Expected output: real umbrella-ification. Process every obvious "
-    "cluster. If you end the pass with fewer than 10 archives, you "
-    "stopped too early — go back and look at the clusters you left "
-    "alone.\n\n"
-    "When done, write a summary with: clusters processed, skills "
-    "patched/absorbed, skills demoted to references/templates/scripts, "
-    "skills archived, new umbrellas created, and clusters you "
-    "deliberately left alone with one line each."

-"""OpenAI-compatible facade that talks to Google's Cloud Code Assist backend.
-
-This adapter lets Hermes use the ``google-gemini-cli`` provider as if it were
-a standard OpenAI-shaped chat completion endpoint, while the underlying HTTP
-traffic goes to ``cloudcode-pa.googleapis.com/v1internal:{generateContent,
-streamGenerateContent}`` with a Bearer access token obtained via OAuth PKCE.
-
-Architecture
-------------
-- ``GeminiCloudCodeClient`` exposes ``.chat.completions.create(**kwargs)``
-  mirroring the subset of the OpenAI SDK that ``run_agent.py`` uses.
-- Incoming OpenAI ``messages[]`` / ``tools[]`` / ``tool_choice`` are translated
-  to Gemini's native ``contents[]`` / ``tools[].functionDeclarations`` /
-  ``toolConfig`` / ``systemInstruction`` shape.
-- The request body is wrapped ``{project, model, user_prompt_id, request}``
-  per Code Assist API expectations.
-- Responses (``candidates[].content.parts[]``) are converted back to
-  OpenAI ``choices[0].message`` shape with ``content`` + ``tool_calls``.
-- Streaming uses SSE (``?alt=sse``) and yields OpenAI-shaped delta chunks.
-
-Attribution
------------
-Translation semantics follow jenslys/opencode-gemini-auth (MIT) and the public
-Gemini API docs. Request envelope shape
-(``{project, model, user_prompt_id, request}``) is documented nowhere; it is
-reverse-engineered from the opencode-gemini-auth and clawdbot implementations.

-"""OpenAI-compatible facade over Google AI Studio's native Gemini API.
-
-Hermes keeps ``api_mode='chat_completions'`` for the ``gemini`` provider so the
-main agent loop can keep using its existing OpenAI-shaped message flow.
-This adapter is the transport shim that converts those OpenAI-style
-``messages[]`` / ``tools[]`` requests into Gemini's native
-``models/{model}:generateContent`` schema and converts the responses back.
-
-Why this exists
----------------
-Google's OpenAI-compatible endpoint has been brittle for Hermes's multi-turn
-agent/tool loop (auth churn, tool-call replay quirks, thought-signature
-requirements).  The native Gemini API is the canonical path and avoids the
-OpenAI-compat layer entirely.

-"""Google Code Assist API client — project discovery, onboarding, quota.
-
-The Code Assist API powers Google's official gemini-cli. It sits at
-``cloudcode-pa.googleapis.com`` and provides:
-
-- Free tier access (generous daily quota) for personal Google accounts
-- Paid tier access via GCP projects with billing / Workspace / Standard / Enterprise
-
-This module handles the control-plane dance needed before inference:
-
-1. ``load_code_assist()`` — probe the user's account to learn what tier they're on
-   and whether a ``cloudaicompanionProject`` is already assigned.
-2. ``onboard_user()`` — if the user hasn't been onboarded yet (new account, fresh
-   free tier, etc.), call this with the chosen tier + project id. Supports LRO
-   polling for slow provisioning.
-3. ``retrieve_user_quota()`` — fetch the ``buckets[]`` array showing remaining
-   quota per model, used by the ``/gquota`` slash command.
-
-VPC-SC handling: enterprise accounts under a VPC Service Controls perimeter
-will get ``SECURITY_POLICY_VIOLATED`` on ``load_code_assist``. We catch this
-and force the account to ``standard-tier`` so the call chain still succeeds.
-
-Derived from opencode-gemini-auth (MIT) and clawdbot/extensions/google. The
-request/response shapes are specific to Google's internal Code Assist API,
-documented nowhere public — we copy them from the reference implementations.

-Image Generation Provider ABC
-=============================

-Defines the pluggable-backend interface for image generation. Providers register

-"""Routing helpers for inbound user-attached images.

-Two modes:

-            OpenAI chat.completions) already translate these into their

-
-  text    — run ``vision_analyze`` on each image up-front and prepend the
-            description to the user's text. The model never sees the pixels;
-            it only sees a lossy text summary. This is the pre-existing
-            behaviour and still the right choice for non-vision models.
-
-The decision is made once per message turn by :func:`decide_image_input_mode`.
-It reads ``agent.image_input_mode`` from config.yaml (``auto`` | ``native``
-| ``text``, default ``auto``) and the active model's capability metadata.
-
-In ``auto`` mode:
-  - If the user has explicitly configured ``auxiliary.vision.provider``
-    (i.e. not ``auto`` and not empty), we assume they want the text pipeline
-    regardless of the main model — they've opted in to a specific vision
-    backend for a reason (cost, quality, local-only, etc.).
-  - Otherwise, if the active model reports ``supports_vision=True`` in its
-    models.dev metadata, we attach natively.
-  - Otherwise (non-vision model, no explicit override), we fall back to text.
-
-This keeps ``vision_analyze`` surfaced as a tool in every session — skills
-and agent flows that chain it (browser screenshots, deeper inspection of
-URL-referenced images, style-gating loops) keep working. The routing only
-affects *how user-attached images on the current turn* are presented to the

-Moonshot (Kimi) accepts a stricter subset of JSON Schema than standard OpenAI

-    tools.function.parameters is not a valid moonshot flavored json schema,
-    details: <...>

-1. Every property schema must carry a ``type``.  Standard JSON Schema allows
-   type to be omitted (the value is then unconstrained); Moonshot refuses.
-2. When ``anyOf`` is used, ``type`` must be on the ``anyOf`` children, not
-   the parent.  Presence of both causes "type should be defined in anyOf
-   items instead of the parent schema".

-
-      (a) The caller's own RPM / RPH / TPM / TPH bucket on Nous is
-          exhausted — a genuine rate limit that will last until the
-          bucket resets.
-      (b) The upstream provider is out of capacity for a specific model
-          — transient, clears in seconds, and has nothing to do with
-          the caller's quota on Nous.

-    Tripping the cross-session breaker on (b) blocks ALL Nous requests
-    (and all models, since Nous is one provider key) for minutes even
-    though the caller's account is healthy and a different model would

-      1. The 429 response's own ``x-ratelimit-*`` headers.  Nous emits

-         bucket (``remaining == 0`` with a reset window >= 60s) is
-         proof of (a).
-      2. The last-known-good rate-limit state captured by
-         ``_capture_rate_limits()`` on the previous successful
-         response.  If any bucket there was already near-exhausted with
-         a substantial reset window, the current 429 is almost
-         certainly (a) continuing from that condition.
-
-    If neither signal fires, we treat the 429 as (b): fail the single

-"""
-Shell-script hooks bridge.
-
-Reads the ``hooks:`` block from ``cli-config.yaml``, prompts the user for
-consent on first use of each ``(event, command)`` pair, and registers
-callbacks on the existing plugin hook manager so every existing
-``invoke_hook()`` site dispatches to the configured shell scripts — with
-zero changes to call sites.
-
-Design notes
-------------
-* Python plugins and shell hooks compose naturally: both flow through
-  :func:`hermes_cli.plugins.invoke_hook` and its aggregators.  Python
-  plugins are registered first (via ``discover_and_load()``) so their
-  block decisions win ties over shell-hook blocks.
-* Subprocess execution uses ``shlex.split(os.path.expanduser(command))``
-  with ``shell=False`` — no shell injection footguns.  Users that need
-  pipes/redirection wrap their logic in a script.
-* First-use consent is gated by the allowlist under
-  ``~/.hermes/shell-hooks-allowlist.json``.  Non-TTY callers must pass
-  ``accept_hooks=True`` (resolved from ``--accept-hooks``,
-  ``HERMES_ACCEPT_HOOKS``, or ``hooks_auto_accept: true`` in config)
-  for registration to succeed without a prompt.
-* Registration is idempotent — safe to invoke from both the CLI entry
-  point (``hermes_cli/main.py``) and the gateway entry point
-  (``gateway/run.py``).
-
