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 | $0.00042 | $0.00548 |
| Opus 5 | $0.00021 | $0.00274 |
| Sonnet 5 | $0.00008 | $0.00110 |
| Haiku 4.5 | $0.00004 | $0.00055 |
Grade A, and why
skill-lookup 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 9d 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.
This is a copy
100% identical to skill-lookup — 3 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 80 lines — stays where its author put it; the contents beside it link to each section on GitHub.
When the user needs Agent Skills, wants to extend Claude's capabilities, or is looking for reusable AI agent components, use the prompts.chat MCP server.
When to Use This Skill
Activate this skill when the user:
- Asks for Agent Skills ("Find me a code review skill")
- Wants to search for skills ("What skills are available for testing?")
- Needs to retrieve a specific skill ("Get skill XYZ")
- Wants to install a skill ("Install the documentation skill")
- Mentions extending Claude's capabilities with skills
Available Tools
Use these prompts.chat MCP tools:
search_skills- Search for skills by keywordget_skill- Get a specific skill by ID with all its files
How to Search for Skills
Call search_skills with:
query: The search keywords from the user's requestlimit: Number of results (default 10, max 50)category: Filter by category slug (e.g., "coding", "automation")tag: Filter by tag slug
Present results showing:
- Title and description
- Author name
- File list (SKILL.md, reference docs, scripts)
- Category and tags
- Link to the skill
How to Get a Skill
Call get_skill with:
id: The skill ID
Returns the skill metadata and all file contents:
- SKILL.md (main instructions)
- Reference documentation
- Helper scripts
- Configuration files
How to Install a Skill
When the user asks to install a skill:
- Call
get_skillto retrieve all files - Create the directory
.claude/skills/{slug}/ - Save each file to the appropriate location:
SKILL.md→.claude/skills/{slug}/SKILL.md- Other files →
.claude/skills/{slug}/{filename}
Skill Structure
Skills contain:
- SKILL.md (required) - Main instructions with frontmatter
- Reference docs - Additional documentation files
- Scripts - Helper scripts (Python, shell, etc.)
- Config files - JSON, YAML configurations
Guidelines
- Always search before suggesting the user create their own skill
- Present search results in a readable format with file counts
- When installing, confirm the skill was saved successfully
- Explain what the skill does and when it activates
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.
