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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00000 | $0.01321 |
| Opus 5.5 | $0.00000 | $0.00528 |
| Sonnet 5.5 | $0.00000 | $0.00264 |
| Haiku 4.5 | $0.00000 | $0.00132 |
Grade A, and why
documentation-testing 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 1mo 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.
Asks for rootlowPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.
| **Permissions** | File/directory permissions, sudo requirements | Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.
How it starts
The opening of the file, as written. The whole thing — 175 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Documentation Testing Skill
Purpose
Provides systematic heuristics for identifying incomplete, outdated, or broken documentation. This skill helps catch the gaps that make onboarding painful for new developers.
Common Documentation Failures
Missing Prerequisites
Projects often assume these are installed without documenting them:
| Category | Examples |
|---|---|
| JavaScript | Node.js, npm, yarn, pnpm (and which version) |
| Python | Python, pip, poetry, conda (and which version) |
| Containers | Docker, docker-compose, podman |
| Databases | PostgreSQL, MySQL, Redis, MongoDB, SQLite |
| Cloud CLIs | aws, gcloud, az, terraform |
| Build tools | make, cmake, gcc, clang |
| Version managers | nvm, pyenv, rbenv, asdf |
Missing Environment Configuration
Look for these patterns that indicate undocumented environment variables:
| Language | Pattern to detect |
|---|---|
| JavaScript/TypeScript | process.env.XXX |
| Python | os.environ["XXX"] or os.getenv("XXX") |
| Ruby | ENV["XXX"] |
| Go | os.Getenv("XXX") |
| Rust | std::env::var("XXX") |
Red flags:
- References to
.envfiles without.env.example config.yamlwith placeholder values but no instructions- Environment variables mentioned in code but not in README
Incomplete Setup Steps
Common missing steps that break new developer onboarding:
| Step | What's often missing |
|---|---|
| Database setup | createdb, migrations, seed data |
| Service dependencies | Starting Redis, Postgres, etc. before the app |
| SSL/TLS | Local HTTPS setup, certificate generation |
| Host files | /etc/hosts modifications for local domains |
| Ports | Required ports and how to check if they're in use |
| Permissions | File/directory permissions, sudo requirements |
| Git hooks | Pre-commit hooks that need manual setup |
| IDE setup | Extensions, settings, debug configurations |
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.

documentation-testing is a skill published in the GitHub repository jimmc414/claude-code-plugin-marketplace (4 stars, last pushed today), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,321 tokens. A static security scan graded it A with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.

audit-encapsulation
Audit skill-encapsulation violations; remediation runs only behind an explicit fix FILE:LINE. External citations reaching into private surfaces inside .claude/skills/X/ or plugins//skills/X/ (marketplace monorepos) beyond the slash invocation. Use when: 'audit encapsulation', 'find skill leaks', 'skill boundary…
extract-ssot
Deduplicate repeated markdown (rule files, skill bodies, ADRs, docs) into one named source of truth and migrate every call site to cite it by exact heading. Use when the same prose, literal, or concept recurs across files: 'DRY this prose', 'extract a shared rule', 'single source of truth for X', a value-bump diff…
audit-progressive-disclosure
Read-only progressive-disclosure audit of agent-facing instruction markdown: grades each file against always-loaded, invocation-loaded, and on-demand tiers and flags split and disclosure defects. Use when: 'progressive disclosure', 'split this file', 'this file is too long', 'too much context', 'mixed concerns', 'hub…
generate
Build a source-backed AI industry briefing from official vendor publications, configured RSS feeds, GitHub releases, reputable secondary reporting, and user-supplied URLs. Use when: 'ai briefing', 'ai news', 'what's new in AI', 'catch me up on AI', 'prep for AI meeting', 'AI roundup', or 'generate AI slides'.
quiz-me
Post-work comprehension check: a self-contained HTML report of a completed change (context, intuition, decisions) with a quiz at the bottom that tests the human, not the artifact; also recalls prior quizzed work. Non-gating by default; the quizpolicy userConfig tunes offer cadence. Use when the user says 'quiz me'…
firecrawl
Scrape, search, crawl, map, parse, or interact with web pages via the firecrawl-cli binary, writing results to disk instead of streaming them into context. Actions: scrape, search, crawl, map, parse, interact, agent, monitor, developer, research, doctor, search-feedback, credit-usage. Use when: 'scrape this page'…
