playwright-fieldkit AGENTS.md

Repository instructions for Playwright FieldKit, a project for building Playwright-based tools and guides for coding agents. They define where the main skill lives and how its generated copies must be kept in sync.

In plain words
What is it for?
Use them when changing the FieldKit skill, its workflow guidance, generated copies, or supporting scripts, including running the required tests.
Why use it?
They reduce differences between the source skill and the versions distributed to other tools. They also provide checks for changes to scripts or workflow rules.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

playwright-fieldkit AGENTS.md 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

Playwright FieldKit repository instructions

Follow the Portable Agent Authoring guides for every skill or harness change.

  • Edit the portable skill only under .agents/skills/pw-playwright-fieldkit/.
  • Regenerate .claude/skills/pw-playwright-fieldkit/ byte-identically, excluding only machine-local scripts/node_modules/.
  • Keep .clinerules/workflows/pw-playwright-fieldkit.md as a thin skill invocation shim; detailed procedures belong in references/workflows/.
  • Keep the distributable intent rule in rules/shared/pw-playwright-fieldkit.md and preserve the authorized-target boundary.
  • Run npm test from the authoritative skill's scripts/ directory after changing scripts or workflow contracts.
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.
