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.

SkillSpector: 4 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00046 | $0.02288 |
| Opus 5 | $0.00023 | $0.01144 |
| Sonnet 5 | $0.00009 | $0.00458 |
| Haiku 4.5 | $0.00005 | $0.00229 |
Grade A, and why
record-playwright scanned grade A with 1 finding 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 6d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Record Web UI Demo (Playwright)
Drive a real browser with Playwright to capture visual proof of a web UI change: screenshots at one or more viewports (desktop, mobile, etc.) and, optionally, a short video clip. Returns the asset paths so they can be embedded inline in a GitHub PR or comment.
This is the recording primitive for web UI changes. For CLI changes, use /record-asciinema.
Prerequisites
- Playwright available one of:
npx playwright(Node project with@playwright/test, or installed globally)uv run playwright/python -m playwright(Python project withplaywright)
- Chromium browser installed for Playwright (
npx playwright install chromium, orplaywright install chromium). The skill installs it if missing. - A reachable target URL. Either the caller provides one that is already running, or provides a server command the skill starts and tears down.
Inputs
| Input | Meaning | Default |
|---|---|---|
$RECORD_SLUG ($1) |
Filename slug, e.g. login-page |
web-demo |
$RECORD_URL ($2) |
URL to capture, e.g. http://localhost:3000/login |
http://localhost:3000 |
$RECORD_DIR |
Output directory | /tmp/record-playwright |
$RECORD_VIEWPORTS |
Space-separated WxH specs |
1280x720 375x812 (desktop + mobile) |
$RECORD_VIDEO |
Set to any value to also record a video clip | (unset; screenshots only) |
$RECORD_SCENARIO |
Prose describing clicks/nav to perform before capture | (none; capture the URL as-is) |
$RECORD_SERVER_CMD |
Command to start the dev server (skill manages its lifecycle) | (none; assume URL is already up) |

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.
- 6d ago First seen · 256 lines · 46 tokens per session scan A f82083a05076
record-playwright is a skill published in the GitHub repository tomzx/agents (6 stars, last pushed yesterday), licensed MIT. It adds 46 tokens to every session and 2,288 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
