audit

A periodic audit of the project's learning records and rule collection. It looks for useful lessons to promote and outdated or unused guidance to remove.

In plain words
What is it for?
Use it to review learning candidates, inspect recent commits, check for stale rules and dead idioms, find unfinished placeholders, and record charter maintenance debt.
Why use it?
It keeps the project's rules relevant by turning recurring discoveries into guidance and identifying rules, sensors, or folders that no longer reflect the codebase.

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

audit 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 2d 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.

How it starts

The opening of the file, as written. The whole thing — 47 lines — stays where its author put it; the contents beside it link to each section on GitHub.

audit

Full dual-flywheel audit. Learning (capture from review) and Pruning (remove dead rules). Periodic. Read .charter/README.md (flywheels section) and .charter/learning/README.md.

Learning flywheel

  1. Walk .charter/learning/inbox/ and flag candidates that should be promoted.
  2. Run review sensors on recent commits — surface patterns that should become guides.
  3. Capture findings as new inbox entries (see learn.md).

Pruning flywheel

The Pruning flywheel reads the charter-debt sensor and proposes the diff to .charter/corpus/state/charter-debt.md. Categories the sensor surfaces:

  1. Stale rules — guides in .charter/guides/ that no diff has touched in N months.
  2. Dead idioms — idiom dirs whose stack is no longer in CODEBASE_STATE.md.
  3. Placeholders — bootstrap <...> markers left unfilled.
  4. Failing sensors — sensors recorded as available that error on invocation.
  5. Empty shells — scaffolded dirs with no real content.
  6. Uncited policies — installed policies whose guides were never referenced.
  7. Unresolved gaps.charter/adapters/<agent>/<topic>.md TODO placeholders.
  8. Drifted statestack-drift findings + CODEBASE_STATE.md stale-last_reconciled.
  9. Strict-cascade violations — run keystone policy verify; any strict-violation output is a hard debt entry. A project file at .charter/<kind>/<name>.md is overriding a strict item from a team or org policy. Remove the shadowing file or escalate to the policy owner.
  10. Required-item gaps — same keystone policy verify run. Required items with no definition anywhere in the cascade are advisory debt: the project is expected to define them at .charter/<kind>/<name>.md. Pruning surfaces them; the project decides which to fill in.

Then update the empirical state files:

  1. Risk fingerprint — read .charter/sensors/risk-fingerprint.md and update .charter/corpus/state/risk-fingerprints.md.
  2. Traffic topology — read .charter/sensors/traffic-topology.md and update .charter/corpus/state/traffic-topology.md.

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.

audit is a command published in the GitHub repository tacoda/keystone (44 stars, last pushed 2mo ago), licensed MIT. It adds 7 tokens to every session and 786 once invoked, about $0.0000 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
