"Skill Suggestions" in System Prompt + +When the agent starts a conversation, the system prompt already lists available skills. We could add a subtle hint: + +``` +If the user's request would benefit from a skill you don't have, +you can search for one using skill_hub_search and offer to install it. +``` + +This makes Hermes **self-extending** — it can grow its own capabilities during a conversation. + +### 2. Skill Composition + +Skills can declare `related_skills` in frontmatter. When installing a skill, offer to install its related skills too: + +``` +Installing 'k8s-skills'... +This skill works well with: docker-ctl, helm-charts, prometheus-monitoring +Install related skills? [y/N] +``` + +### 3. Skill Snapshots + +Export your entire skills configuration (builtin + hub-installed) as a shareable snapshot: + +```bash +hermes skills snapshot export my-setup.json +hermes skills snapshot import my-setup.json # On another machine +``` + +This enables teams to share curated skill sets. + +### 4. Skill Usage Analytics (Local Only) + +Track which skills get loaded most often (locally, never phoned home): + +```bash +hermes skills stats +# Top skills (last 30 days): +# 1. axolotl — loaded 47 times +# 2. vllm — loaded 31 times +# 3. k8s-skills — loaded 12 times (hub) +# 4. docker-ctl — loaded 8 times (hub) +``` + +### 5. Cross-Ecosystem Publishing + +Since our format is compatible, let Hermes users publish their skills TO ClawHub: + +```bash +hermes skills publish skills/my-custom-skill --to clawhub +``` + +This makes Hermes a first-class citizen in the broader agent skills ecosystem rather than just a consumer. + +### 6. npx skills Compatibility + +Register Hermes as a supported agent in the Vercel skills.sh ecosystem. This means anyone running `npx skills add owner/repo` will see Hermes as an install target alongside Claude Code, Codex, Cursor, etc. The table would look like: + +| Agent | CLI Flag | Project Path | Global Path | +|-------|----------|-------------|-------------| +| **Hermes** | `hermes` | `.hermes/skills/` | `~/.hermes/skills/` | + +This is probably a PR to vercel-labs/skills — they already support 35+ agents and seem welcoming. + +### 7. Marketplace.json for Hermes Skills + +Create a `.claude-plugin/marketplace.json` in the Hermes-Agent repo so Hermes's built-in skills (axolotl, vllm, etc.) are installable by Claude Code users too: + +```json +{ + "name": "hermes-mlops-skills", + "owner": { "name": "Nous Research" }, + "plugins": [ + {"name": "axolotl", "source": "./skills/mlops/axolotl", "description": "Fine-tuning with Axolotl"}, + {"name": "vllm", "source": "./skills/mlops/vllm", "description": "vLLM deployment & serving"} + ] +} +``` + +This is zero-effort marketing — anyone who runs `/plugin marketplace add NousResearch/Hermes-Agent` in Claude Code gets access to our curated ML skills. + +### 8. Trust-Aware Skill Loading + +When the agent loads an external skill, prepend a trust context note: + +``` +[This skill was installed from ClawHub (verified, scanned 2026-02-17). +Trust level: verified. It requires env vars: GITHUB_TOKEN.] +``` + +This lets the model make informed decisions about how much to trust the skill's instructions, especially important given the prompt injection attacks seen in the wild. + +--- + +## Open Questions + +1. **Node.js dependency?** ClawHub CLI is npm-based. Do we vendor it or rewrite the HTTP client in Python? + - Recommendation: Pure Python with httpx. Avoid forcing Node on users. + - Update: The `npx skills` CLI from Vercel is also npm-based but designed as `npx` (no global install needed). Could use it as optional enhancer. + +2. **Default taps?** Should we ship with ClawHub and awesome-openclaw-skills enabled by default, or require explicit opt-in? + - Recommendation: Ship with them as available but not auto-searched. First `hermes skills search` prompts to enable. + - Update: Consider shipping with `openai/skills` and `anthropics/skills` as defaults — these are the official repos with higher trust. + +3. **Auto-install?** Should the agent be able to install skills without user confirmation? + - Recommendation: Never for community sources. Verified/trusted sources could have an "auto-install" config flag, default off. + +4. **Skill conflicts?** What if a hub skill has the same name as a builtin? + - Recommendation: Builtins always win. Hub skills get namespaced: `hub/skill-name` if conflict detected. + - Note: Codex handles this with scope priority (REPO > USER > ADMIN > SYSTEM). We could adopt similar precedence. + +5. **Disk space?** 3,000+ skills on ClawHub, 14,500+ on LobeHub. Users won't install all of them, but should we cache search results or skill indices? + - Recommendation: Cache search results for 1 hour. Don't pre-download indices. Skills are small (mostly markdown), disk isn't a real concern. + +6. **agentskills.io compliance vs Hermes extensions?** Our `tags` and `related_skills` fields aren't in the standard. + - Recommendation: Keep them. The spec explicitly allows `metadata` for extensions. Move them under `metadata.hermes.tags` and `metadata.hermes.related_skills` for new skills, keep backward compat for existing ones. + +7. **Which registries to prioritize?** There are now 8+ potential sources. + - Recommendation for MVP: GitHub adapter only (covers openai/skills, anthropics/skills, awesome lists, any repo). This one adapter handles 80% of use cases. Add ClawHub API in Phase 2. + +8. **Security scanning dependency?** Should we integrate AgentVerus, build our own, or both? + - Recommendation: Start with our own lightweight `skills_guard.py` (regex patterns). Optionally invoke AgentVerus if installed. Don't make it a hard dependency. + + + + + + + + diff --git a/docs/tools.md b/docs/tools.md index a8682d9ce..1bc50a065 100644 --- a/docs/tools.md +++ b/docs/tools.md @@ -155,14 +155,33 @@ skills/ └── axolotl/ ├── SKILL.md # Main instructions (required) ├── references/ # Additional docs - └── templates/ # Output formats, configs + ├── templates/ # Output formats, configs + └── assets/ # Supplementary files (agentskills.io) ``` -SKILL.md uses YAML frontmatter: +SKILL.md uses YAML frontmatter (agentskills.io compatible): ```yaml --- name: axolotl description: Fine-tuning LLMs with Axolotl -tags: [Fine-Tuning, LoRA, DPO] +metadata: + hermes: + tags: [Fine-Tuning, LoRA, DPO] --- ``` + +## Skills Hub + +The Skills Hub enables searching, installing, and managing skills from online registries.
