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 5.1 | $0.00079 | $0.01327 |
| Opus 5.5 | $0.00032 | $0.00531 |
| Sonnet 5.5 | $0.00016 | $0.00265 |
| Haiku 4.5 | $0.00008 | $0.00133 |
Grade A, and why
cookie-consent scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 90 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Cookie Consent
Design a cookie consent implementation for "$ARGUMENTS". Conduct a cookie audit, categorize cookies, design consent mechanisms by jurisdiction, and create an implementation checklist.
Note: AI-generated legal content does not constitute legal advice. Consult a qualified attorney.
Arguments. $ARGUMENTS may contain the project name and optional flags. Take the first token as <project> and treat --skip-checks as a flag; never include flags in file paths. All paths below use <project>. If --skip-checks is present, skip the prerequisite check and, before writing any artifact, append one line to .metapowers/legal/<project>/skip-log.md: - <ISO timestamp> — <skill name> skipped prerequisite check for <artifact file> — reason: <reason or "none given">.
Prerequisites
Check that .metapowers/legal/<project>/00-assess.md exists. If it does not exist, stop and tell the user:
"Run an Assess skill first (e.g.
/legal:risk-assessment <project>) to generate the prerequisite assessment artifact."
Process
-
Read inputs:
- Read
.metapowers/legal/<project>/00-assess.mdfor risk, jurisdiction, and data practice context - Read any existing cookie policy or draft artifacts in
.metapowers/legal/<project>/for additional context
- Read
-
Conduct cookie audit:
- Scan site for all cookies and similar tracking technologies (local storage, session storage, pixels, fingerprinting)
- Document each cookie/tracker: name, provider, purpose, type (first-party vs. third-party), duration (session vs. persistent with expiry)
- Identify all third-party services that set cookies (analytics, advertising, social media, CDN, etc.)
-
Categorize cookies:
- Strictly necessary — essential for site functionality, no consent required (session management, authentication, security, load balancing, cookie consent preferences)
- Functional/Preferences — enable enhanced functionality and personalization (language preference, region selection, user interface customization)
- Analytics/Performance — collect information about site usage (page views, bounce rates, traffic sources, performance monitoring)
- Advertising/Marketing — track visitors across websites for advertising purposes (ad targeting, retargeting, campaign measurement, social media sharing)
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.

cookie-consent is a skill published in the GitHub repository bromso/metapowers (2 stars, last pushed 2d ago), licensed MIT. It adds 79 tokens to every session and 1,327 once invoked, about $0.0003 per session on Opus 5.5. 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 2026-10-21.
