Where files are headingNew AGENTS.md files have more rules about keeping secrets out of the code, and fewer about code style.
Of the AGENTS.md files we read, the 31,774 first seen in the last six months, against the older ones: the kind of rule that gained most share, and the kind that lost most. About files like this in general, not this one, and an estimate, since a kind is a pattern in the words.

The file
We split this AGENTS.md into the rules it gives an agent
1 rule. About 0 are common, 1 is distinctive, and 0 are very specific to this project.
≈0
Common · estimate
Many files like this have a rule of this kind.
≈1
Distinctive · estimate
This author's own choices. Worth a look.
0
Very specific
Tied to their project's names, files or tools. Probably skip.

When any of the following change, update every location below that covers it before marking the task done:
≈ “Common” is an estimate: at least 1 in 5 of the 40,246 AGENTS.md files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Updating docs after API changes
When any of the following change, update every location below that covers it before marking the task done:
- A
caliper runCLI flag is added, removed, or renamed - The
.eval.yamlspec format changes (new fields, removed fields, renamed keys) - The judge behavior changes (how
expect:orassert:are evaluated) - The results JSON schema changes (
RunMeta,AttemptRecord, etc.)
Locations to update:
README.md— CLI reference table, exit codes, and any relevant prose sectionsdocs/spec-reference.md— the full.eval.yamlformat and judging rulesdocs/backends.md— backend setup,--modelsyntax, MCP support by backenddocs/results.md— scoring,caliper compare, and the results JSON schemaskills/evaluate-skill/REFERENCE.md— the source skill referenceskills/grill-skill/REFERENCE.md— the grill-skill reference
tests/test_doc_sync.py fails when a caliper run flag is missing from (or
stale in) the README table or missing from the evaluate-skill reference, and
when a spec key is missing from docs/spec-reference.md. The rest of this list
is still on you.
Formatting
ruff is the single formatting and linting authority for this repo, pinned to
ruff==0.15.20. Run ruff format . and ruff check . before finishing. Never
hand-reformat lines outside the scope of your change — the formatter is the
only style authority, and manual reflow inflates diffs. CI enforces
ruff format --check . and ruff check . on every PR. See
.github/CONTRIBUTING.md for details.
Decision docs
This repo keeps its domain model and design decisions in version control:
docs/CONTEXT.md— the glossary / ubiquitous language. A glossary only: no implementation details, no specs, no scratch notes. This is where the grill-with-docs and domain-modeling skills read and write terms. In this repo it lives atdocs/CONTEXT.md, not the repo root — look there.docs/adr/— Architecture Decision Records (0001-*.md, …), one short entry per hard-to-reverse, non-obvious, real-trade-off decision.
Both are committed and ship with the repo. Reference them freely from code
comments, docstrings, and docs — e.g. see docs/CONTEXT.md → Regression or
docs/adr/0001-attempt-outcome-taxonomy.md. Because the files clone with the
repo, these links resolve for everyone. Prefer a short comment that links the
record over re-explaining the decision inline.

Your trail
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
Now do this for your own.
Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
