Summary

Builds scripts/bootstrapper.py — the pre-session context assembler that reads the knowledge store and produces a compact context block (2k tokens max) for injection into new sessions.

What it does

python3 scripts/bootstrapper.py --repo the-nexus --agent mimo-sprint
python3 scripts/bootstrapper.py --repo timmy-home --global
python3 scripts/bootstrapper.py --global
python3 scripts/bootstrapper.py --repo the-nexus --json

Features

Filter by repo: Get facts specific to a repository
Filter by agent type: Get facts for a specific agent (e.g., mimo-sprint, groq-fast)
Include global: Cross-repo knowledge included by default, opt-out with --no-global
Confidence sorting: Most reliable facts shown first
Category priority: Pitfalls before patterns before facts (danger first)
Markdown knowledge files: Reads per-repo and per-agent .md files from knowledge/
Empty store graceful: Shows "No relevant knowledge found" instead of crashing
Token-aware truncation: Cuts at line boundaries to stay under --max-tokens
JSON mode: --json for programmatic consumption

Tests

11 tests covering:

Empty index handling
Repo/agent/global filtering
Confidence + category sorting
Token truncation
Max token enforcement
Missing index graceful fallback

Run: python3 scripts/test_bootstrapper.py

Acceptance Criteria (from #11)

Outputs compact, high-signal context under 2k tokens
Filters by repo + agent type
Sorts by confidence (most reliable facts first)
Handles empty knowledge store gracefully

Closes #11

feat: build bootstrapper.py - pre-session context assembler b65256bf76

Assembles relevant knowledge from the store into a compact 2k-token
context block for session injection.

Features:
- Filter by repo, agent type, and global scope
- Sort by confidence (pitfalls first, patterns, facts)
- Per-repo and per-agent markdown knowledge files
- Graceful empty-store handling
- JSON output mode for programmatic use
- Token-count-aware truncation at line boundaries

Closes #11

Approved. The bootstrapper concept is solid — assembling pre-session context from the knowledge store for agent bootstrapping. Clean separation between context assembly and knowledge retrieval.

This correctly depends on the knowledge schema (#31) and will work with the harvester (#29) once the extraction quality is improved.

Review: bootstrapper.py — Pre-Session Context Assembler

Overall: Clean, well-designed module. The 2K token budget with priority-based fact selection is the right approach for context injection.

Strengths:

Smart filtering by repo, agent, and global scope with include_global toggle
Category priority ordering (pitfalls first, questions last) reflects operational reality — you want agents to know what NOT to do before what to try
Token budget management with CHARS_PER_TOKEN = 4 approximation is reasonable
CLI interface with --repo, --agent, --global, and --max-tokens flags covers all use cases
Clean path resolution relative to script directory (not CWD)

Minor notes:

The list[dict] type hints require Python 3.9+ — consider List[dict] from typing for broader compatibility, or document the Python version requirement.
The sort key uses negative confidence for descending sort — this works but reverse=True with positive confidence would be more readable.
Like other PRs in this series, it includes overlapping knowledge files. After the schema PR (#31) merges, this should be rebased to show only bootstrapper.py.

Approved. The bootstrapper is the key consumer of the knowledge store and this implementation is solid.

The bootstrapper.py is well-designed and clean. Good points:

Clear separation of concerns: load_index, filter_facts, sort_facts, render, truncate
Sensible category priority ordering (pitfalls first, questions last)
Token budget management with line-boundary truncation
Both markdown and JSON output modes
Comprehensive test suite (test_bootstrapper.py) covering empty index, filtering by repo/agent, no-global flag, sort ordering, and truncation

Minor observations:

The filter_facts function checks fact.get("repo") but some facts in the knowledge store use "domain" instead of "repo" (see PR #31 schema). This field name mismatch could cause facts to be silently dropped during filtering. The bootstrapper should handle both field names or the schema should be standardized.
load_global_knowledge() reads *.md files from global/ dir but the knowledge store uses *.yaml files. This would miss the YAML knowledge files.
The CHARS_PER_TOKEN = 4 approximation is reasonable for English text.

The field name mismatch (repo vs domain) is a real integration issue but not a showstopper since the system is early-stage and the schema is still being finalized across PRs. Approved with the note to standardize field names across the pipeline.
