A skill for finding and installing coding-agent skills from several public registries. It searches for matching skills, compares their quality and suitability, and presents the results before installation.

Use it to search for a skill by topic, inspect available matches, choose one, and install it for a coding agent.

It saves you from manually searching multiple skill directories when the current agent lacks the expertise needed for a task.

skill-fetch — Skill for Claude Code by girofu

Install

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.

Any agent

npx skills add girofu/skill-fetch --skill skill-fetch

Clone the repo

git clone --depth 1 https://github.com/girofu/skill-fetch

Made for: Claude Code.

Or install skill-fetch, the plugin that ships this one along with the rest of its 1 skill, 2 commands.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00092	$0.03378
Opus 5	$0.00046	$0.01689
Sonnet 5	$0.00018	$0.00676
Haiku 4.5	$0.00009	$0.00338

Security

Grade A, and why

skill-fetch 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 7d ago.

The scan reads SKILL.md. This mod also ships 3 executable files (scripts/fetch-skill-bundle.sh, scripts/fetch-skillhub.sh, scripts/fetch-skills-directory.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Makes network callslowCapability

Not a fault in itself. Listed so you know the mod talks to something, and to what.

How it starts

The opening of the file, as written. The whole thing — 184 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Skill Fetch

Search, score, and install agent skills from multiple registries in parallel.

When to Use

A skill-eval hook outputs "MISSING EXTERNAL SKILL"
The current task requires domain expertise not available locally
The user asks to "fetch skill", "search for a skill", or "install a skill"

Critical Rules

Never use skillsmp_get_skill_content to preview before deciding — search descriptions are sufficient. Only use as a fallback if installation fails.
Stop on first results, continue only on zero (max 5 rounds) — any round with ≥1 result proceeds to analysis.
Only the user can decide to skip — the LLM must never skip installation on its own.
Always use plain-text interaction — do not use AskUserQuestion. Output analysis and wait for the user to reply with a number or command.
Show up to 5 results per page — with full analysis (content, pros, cons, repo URL) so the user can make an informed decision.

Platform Compatibility

This skill works across 6+ AI coding agents (Claude Code, Cursor, Codex, Gemini CLI, Windsurf, Amp). Tool names adapt automatically. See references/platform-adapters.md for the full mapping table.

Procedure

Step 0: SkillsMP MCP Self-Check (Claude Code only)

Before searching, verify that the SkillsMP MCP server is available:

First, try loading deferred tools: Run ToolSearch("skillsmp") to load any deferred SkillsMP MCP tools. In Claude Code, MCP tools are often deferred (not loaded until requested) and have namespaced names like mcp__skillsmp__skillsmp_search. The ToolSearch call resolves these.
After ToolSearch, check if any skillsmp_* or mcp__skillsmp__* tool is now available
If available → proceed to Step 1
If still not available → run: claude mcp add --scope user skillsmp -- npx -y skillsmp-mcp-server
Inform the user: "SkillsMP MCP server has been registered. It will be available after restarting the session. Continuing search with the remaining 7 sources for now."
Proceed to Step 1 (SkillsMP sources will be skipped this session, but available in future sessions)

Files

What ships with it

9 files 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.

Changes

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.

skill-fetch is a skill published in the GitHub repository girofu/skill-fetch (30 stars, last pushed 3mo ago), licensed MIT. It adds 92 tokens to every session and 3,378 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
