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.
In this repository6 other files it gives its agents.

The file
We split this AGENTS.md into the rules it gives an agent
10 rules. About 0 are common, 8 are distinctive, and 2 are very specific to this project.

≈ “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.

ChatCut agent instructions
These instructions apply to all work under chatcut-production-mirror/.
Shift Testing Left
Keep the fast local and CI gates early:
npm testnpm run buildnpm run verify:distnpm run ci:checkfor PR/local verificationnpm run ci:predeploybefore Vercel publishes the output
These checks are necessary but are not sufficient to call a product/UI change ready.
Real Preview acceptance
After a Vercel Preview URL exists, use deterministic browser automation as the required post-preview acceptance gate.
Preferred runners:
- Playwright against the exact Vercel Preview URL.
- Vercel
agent-browserwhen an agent is performing the verification interactively.
Do not substitute a static fetch, build success, or verify:dist result for this browser check.
If Deployment Protection is enabled, use Vercel's automation bypass support such as VERCEL_AUTOMATION_BYPASS_SECRET instead of relying on manually generated share links.
Verify at minimum:
/renders as the expected ChatCut production mirror without an obvious 404 or broken critical assets./intent.htmlis reachable and visibly renders.- Representative
/features/...routes used by the change are reachable. - At least one affected homepage/demo interaction is exercised through the visible UI and reaches its expected visible result/state.
- No framework error overlay or relevant browser console error appears during the checked flow.
- Capture a screenshot and an interactive/DOM snapshot when the runner supports them.
- When a stable visual baseline exists, run a screenshot diff and treat a material unexpected difference as an acceptance failure.
Any route, asset, interaction, console-visible failure, or access blocker discovered by the browser run is a real acceptance failure until resolved.
TinyFish policy
TinyFish is optional exploratory acceptance, not the default or mandatory PR gate.
Use TinyFish only when human-like autonomous exploration adds value beyond the deterministic Playwright/agent-browser checks, or when the user explicitly requests it. Do not make a PR depend on metered TinyFish availability when the same acceptance criteria can be expressed deterministically.
If TinyFish is unavailable, out of credits, or blocked by account capabilities, that does not block the PR when the required Playwright/agent-browser Preview acceptance passes.
PR evidence
After the real Preview browser run, leave or update PR evidence containing:
- the exact Preview URL tested;
- the browser runner used and run/artifact URL when available;
- PASS / FAIL / BLOCKED;
- routes and interaction(s) exercised;
- screenshot/snapshot or visual-diff artifact references when available;
- concrete failures or blockers;
- queue, execution, and end-to-end timing separately when available.
Do not mark a product/UI PR ready for final human review only because local tests, GitHub Actions, or Vercel build checks are green. The real Preview browser acceptance must also pass.

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.
