quality

A command that runs Fettle's complete quality scan on the current project.

In plain words
What is it for?
Checking the project, grouping findings by severity, suggesting fixes, applying automatic fixes, updating a baseline, or running a cross-review.
Why use it?
It collects quality findings in one place and points out new or serious problems that may otherwise be missed.

Per session 12 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 156 The whole file, excluding the scripts and references it only reads on demand.

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

quality 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.

What it actually says

Run fettle check --all (pass any additional arguments from $ARGUMENTS).

Present the results to the user, grouped by severity. If there are errors, suggest specific fixes based on the rule messages. If a baseline is available, highlight only new findings.

After presenting results, offer to:

  1. Fix the errors automatically (if any) with fettle check --fix
  2. Update the baseline with fettle baseline update
  3. Run a cross-review with python3 -m fettle.cross_review
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.
