kw-engine: Instructions file for Claude Code

CLAUDE.md

kw-engine CLAUDE.md is an instructions file for Claude Code from chenpg2/kw-engine. It costs 189 tokens per session, scanned A, a copy of kw-engine AGENTS.md, MIT.

Repository instructions for kw-engine, a tool that turns research notes into organized knowledge and searchable indexes. Markdown files are the source, while the SQLite database and index are generated from them.

In plain words
What is it for?
Use them when rebuilding or checking indexes, viewing project status, running tests, linting, type-checking, or changing the knowledge models and storage code.
Why use it?
They prevent the stored data and its indexes from drifting apart and define checks for invalid records, code boundaries, and pending work.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

kw-engine CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

95% identical to kw-engine AGENTS.md — 2 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Commands

uv run kw reindex --memory-dir path   # rebuild SQLite + index.json from markdown
uv run kw verify --memory-dir path    # run SCHEMA §6 invariants
uv run kw status --memory-dir path    # show counts + pending/stale state
uv run pytest                          # all tests
uv run ruff check .                    # lint
uv run mypy src/                       # type check

Conventions

  • Markdown is truth; SQLite + index.json are derived (kw reindex rebuilds both)
  • Paper id = PDF filename stem
  • Principle id = P-#### (zero-padded)
  • All models in models.py; store/ never imports from cli.py
  • No silent fallback: validation errors raise, never coerce.
Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
