A lasting record of a codebase's features, tests, and known defects. It uses the Ratchet command-line tool so quality information can be queried instead of remembered.

Use it to catalogue features with evidence, link tests to those features, and track defects with their severity and status.

It preserves what has been checked across sessions and makes missing tests, failed tests, and unresolved defects visible.

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.

Model	Per session	Once invoked
Fable 5	$0.00067	$0.00712
Opus 5	$0.00034	$0.00356
Sonnet 5	$0.00013	$0.00142
Haiku 4.5	$0.00007	$0.00071

Security

Grade A, and why

qa-ledger 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.

/ratchet:qa-ledger — the canonical quality ledger

Session state is "this session." The ledger is "everything we know about this codebase's quality surface." This command builds and maintains it. It is the memory that lets QA compound instead of restarting every session.

Step 0 — Ensure the ledger exists

ratchet ledger create
ratchet ledger get

Procedure

Features — from /ratchet:repo-audit evidence (or discover now). Each feature is a row with a stable ID, area, the routes/workflows it covers, and a status (discovered → specced → covered → verified).
```
ratchet ledger update features '{"name":"checkout","area":"commerce","routes":"/cart,/pay","status":"discovered"}'
```
Tests — every test that exists or must exist, tied to a feature, with a kind (unit / integration / e2e / manual) and status (pass / fail / missing).
```
ratchet ledger update tests '{"feature":"<feature id>","name":"pay-with-expired-card","kind":"e2e","status":"missing"}'
```
Defects — every known failure enters through the defect verbs, never through a generic ledger edit: the state defect family owns the mirror's status, severity, and summary end-to-end, so ratchet defect add is the only birth door (it lands in the ledger automatically).
```
ratchet defect add '{"feature":"<feature id>","severity":"high","summary":"..."}'
```
Reconcile. Update statuses for anything that changed since last session — through the verbs that own each record. A test that now passes or a feature now covered reconciles with ratchet ledger update tests|features ...; a defect reconciles only through its lifecycle:
```
ratchet defect resolve <id> --evidence "<proof it is actually fixed>"
ratchet defect reopen <id> --reason "<why it is not actually fixed>"
ratchet defect supersede <id> --by <newId>
```

Rules

Every feature must have evidence and at least one intended test. A feature with no test row is itself a defect — record the gap.
Never mark a feature verified without a passing test to point to.
Use stable IDs so updates upsert instead of duplicating.

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.

qa-ledger is a skill published in the GitHub repository Megaprompting/torque-loop (5 stars, last pushed 1mo ago), licensed MIT. It adds 67 tokens to every session and 712 once invoked, about $0.0003 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 2026-08-31.
