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 | $0.04273 | $0.04273 |
| Opus 5 | $0.02136 | $0.02136 |
| Sonnet 5 | $0.00855 | $0.00855 |
| Haiku 4.5 | $0.00427 | $0.00427 |
Grade D, and why
Purchasely-AI-Plugin CLAUDE.md scanned grade D with 3 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 5d 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.
Hidden instructionshighPrompt injection
Directives inside HTML comments, invisible characters or bidirectional overrides are read by the model and not by the person reviewing the file.
<!-- rtk-instructions v2 --> Sends data to an external URLmediumData exfiltration
A POST to an outside endpoint may be telemetry or may be exfiltration; either way the mod talks to somewhere, and you should know where.
const r = await fetch("https://agentskill.sh/api/skills/submit", { method: "POST", Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.
### curl / wget — BLOCKED How it starts

CHANGELOG must be kept up to date
Every PR that adds, changes, removes, or deprecates anything user-visible must update CHANGELOG.md:
- Add the entry under the top-level
## [Unreleased]section, in the appropriate sub-section:Added,Changed,Removed,Deprecated,Fixed,Security. - Keep entries short, factual, and user-facing. Example:
Added references/concepts/promotional-offers.md — covers Apple promo offers, Google developer-determined offers, offer codes— notReworked the references directory. - When cutting a release, rename
[Unreleased]to[X.Y.Z] — YYYY-MM-DDand add a fresh empty[Unreleased]section at the top — see Release process below for the full, authoritative list of manifests to bump. - Format follows Keep a Changelog. Versioning follows SemVer.
Rule of thumb: if you wouldn't write the change in the release notes a client reads, you probably don't need a CHANGELOG entry. Otherwise, write one.
Release process
Releases are cut directly on main — there is no release PR.

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.
