skill-lookup

skill-lookup is a skill for Claude Code, Codex from LuizEduPP/Rememb. It costs 50 tokens per session (681 once invoked), scanned A, original, MIT.

A guide for searching, inspecting, and installing Agent Skills from a registry. It covers the skill files, metadata, target installation folder, and verification of the saved result.

In plain words
What is it for?
Use it to find skills by topic, inspect a candidate's contents, retrieve the full package, install it into a skill directory, and check its SKILL.md file.
Why use it?
It gives a repeatable process for extending an AI assistant with reusable capabilities. This helps confirm that the selected skill is appropriate and installed correctly.

Token cost

What it costs to keep this loaded

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.

Security

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 4d 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.

Skill Lookup

Overview

Use this skill to search a skill registry, inspect candidate skills, and install selected skills into a concrete <skill-root> without assuming a specific assistant or editor.

When to Use

Use this skill when the user wants to:

  • find an existing skill before building one
  • browse a registry by topic, category, or tag
  • inspect the files included in a skill
  • install a skill into a local or project skill directory

Core Workflow

  1. Search the registry with search_skills using the user's task, domain, and likely triggers.
  2. Present concise results with title, description, author, and file summary.
  3. If the user selects a candidate, fetch the full package with get_skill.
  4. Ask for or infer the target <skill-root> for installation.
  5. Save SKILL.md and any companion files under <skill-root>/{slug}/.
  6. Verify that the saved SKILL.md is present and that the frontmatter is intact.
  7. Explain what the installed skill does and when it should activate.

Available Tools

  • search_skills: Search for skills by keyword, category, or tag
  • get_skill: Retrieve one skill with all files and metadata

Inputs / Assumptions

  • query should reflect the user's actual problem, not just a generic domain label
  • limit should stay small enough to review meaningfully
  • category and tag filters are optional refinements, not mandatory inputs
  • Installation should use a real <skill-root> chosen for the current environment

Examples

Example search

search_skills({"query": "code review", "limit": 5, "category": "coding"})

Example retrieval

get_skill({"id": "abc123"})

Example installation layout

<skill-root>/skill-slug/
├── SKILL.md
├── reference.md
└── scripts/

Optional Host Notes

  • Some environments expose separate user-level and workspace-level skill roots. Treat that as a deployment choice rather than a requirement of the skill itself.
  • Some environments refresh skills automatically, while others need reload, reindex, or restart before a new installation becomes visible.
  • If the user explicitly asks for host-specific installation steps, provide them after the generic workflow is clear.

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.
