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.

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 | $0.00040 | $0.00823 |
| Opus 5 | $0.00020 | $0.00411 |
| Sonnet 5 | $0.00008 | $0.00165 |
| Haiku 4.5 | $0.00004 | $0.00082 |
Grade A, and why
playwright 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 today.
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.
How it starts
The opening of the file, as written. The whole thing — 44 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Playwright
Use Playwright for browser automation and end-to-end tests. Test strategy belongs to quality-assurance and interface critique to product-design-review; this skill owns the tool: browsers, commands, and the official skills.
Workflow
- Pin the browser:
playwright install chromium; the mise binary is the global CLI, and a project pins@playwright/testwith pnpm per typescript-stack. If Linux system libraries are missing, report the administrator-owned prerequisite instead of invoking the privilegedinstall-depscommand. - Explore and record:
playwright codegen <url>records actions into a test;playwright screenshot <url> <file>andplaywright pdf <url> <file>produce review evidence. - Run tests:
playwright testin a project withplaywright.config.ts; add--trace onwhen a failure needs context, thenplaywright show-trace <trace.zip>orplaywright show-report. - Expose the browser to agents:
playwright mcpserves the browser over MCP per agent-mcp;playwright init-agents --loop <claude|codex|copilot|opencode>seeds planner, generator, and healer agents. - Verify: a green
playwright testrun plus the artifact (screenshot, trace, or report) the task asked for.
Gotchas
- Authority: a test request does not authorize reusing a logged-in browser, synchronizing cookies, entering passwords or MFA, creating accounts, bypassing CAPTCHA, accepting legal terms, making purchases, or paying for cloud browsers or tunnels; stop and ask.
- Browser cache: binaries live in
~/.cache/ms-playwright;playwright uninstallfrees them (see reclaim-disk). - Version skew: browsers match the Playwright version that installed them; rerun
playwright installafter an upgrade. - Headless by default: pass
--headedto watch a run; keep CI headless.
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.

playwright is a skill published in the GitHub repository fmind/dot (4 stars, last pushed today), licensed MIT. It adds 40 tokens to every session and 823 once invoked, about $0.0002 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 2026-09-03.
