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 | $0.00027 | $0.00604 |
| Opus 5.5 | $0.00011 | $0.00242 |
| Sonnet 5.5 | $0.00005 | $0.00121 |
| Haiku 4.5 | $0.00003 | $0.00060 |
Grade A, and why
claude-plugin-guide 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 15d 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.
What it actually says
Claude plugin authoring reference
Resolve the RU/EN question into the relevant manifest, component, marketplace, hook, or installation topic. Return a concise answer with source paths and supported examples. This is read-only product guidance: do not install, enable, update, launch, or repair plugins, execute Claude commands, or self-update this guide.
Read only references relevant to the question:
- Native Claude product-authoring rules: distributed Claude skill frontmatter, prompt-first invocation, setup lifecycle, and validation; excludes native Codex skills.
- Product skill-authoring reference, frontmatter catalog, and prompt contract: canonical tracked skill contracts. Agent-return-setup demonstrates structural frontmatter/PLAN/lifecycle, not default routing: its default descriptions conflict. Validate affected product skill directories with
bash brewcode/skills/skills/scripts/validate-skill.sh <affected-skill-directory>. - Setup defaults are per skill: compare documented behavior with executable resolution and report disagreements. Teams' parser and docsync use installed status/absent install; semble routing defaults to read-only status, never a bare machine-level install.
- Product agent-authoring reference: tracked Claude agent contracts, distinct from native
.codex/agents/*.toml. - Product hook reference: tracked Claude product hook contracts; embedded commands and Claude tools are reference text, never executable Codex instructions.
- Relevant tracked manifests under each product's
.claude-plugin/and itsskills/,agents/, andhooks/: actual implementation. Locate withrg --files; inspect focused ranges. - Official plugin reference, marketplace reference, and plugin guide: verify current or uncertain behavior before presenting it as current.
Distinguish tracked implementation, dated reference claims, and verified official behavior. Report source disagreements with evidence. Claude manifests and substitution tokens describe the shipped Claude product; native Codex uses project instructions, skills, agents, and tools with plugins disabled.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

claude-plugin-guide is a skill published in the GitHub repository kochetkov-ma/claude-brewcode (32 stars, last pushed today), licensed MIT. It adds 27 tokens to every session and 604 once invoked, about $0.0001 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 2026-10-01.
