Triage is an agent skill from PrefectHQ/fastmcp. Find worthwhile FastMCP issues to work on in a backlog or release window, verify promising candidates, and present concrete picks with existing PR links.
Its SKILL.md is about 570 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Agent Workflows, covering MCP servers. It works with Model Context Protocol. The repository describes itself as: 🚀 The fast, Pythonic way to build MCP servers and clients. The licence is Apache-2.0.
Read from SKILL.md and the folder at commit e2fcc41. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Shell commands in SKILL.md call:
ghFrom the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md. Its commands use gh, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Triage loads about 573 tokens when it runs. Until then it costs about 40 tokens; SKILL.md has 257 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

.claude/skills/triage/SKILL.md (or your agent's skills folder).Read AGENTS.md and the contribution policy in the development guide. Honor the requested scope. For "since the last patch," identify the release timestamp, then look for open issues created or substantively updated afterward. Use a bounded inventory internally; report truncation if it affects coverage.
Start from an inventory, then link each candidate to the PRs that mention it:
gh release list --repo PrefectHQ/fastmcp --limit 1
gh issue list --repo PrefectHQ/fastmcp --state open --limit 30 \
--json number,title,author,createdAt,updatedAt,labels,comments
gh pr list --repo PrefectHQ/fastmcp --state all --search "<issue-number> in:body" \
--json number,title,state,authorPick work with concrete user impact, a supported contract being violated, and a tractable causal fix. Do not rank solely by recency, comment count, or how small a proposed patch looks. Automated dashboard churn is not itself useful work.
For promising candidates:
Lead with the strongest pick as soon as evidence supports it: link, what breaks, why it matters, where the cause is, and the next action. Include a few alternatives when useful. Do not turn selection into an exhaustive audit or a full review of every linked PR. Save continuation notes only when needed.
When the user chooses implementation, use fix-issue. For an assignment decision on an external contribution, use review-issue. Triage alone does not authorize public mutations or implementation.

anthropics/skills
Guides the design and implementation of Model Context Protocol servers in TypeScript or Python, from tool naming and error messages to evaluation.

Walks through building MCP servers in Python or TypeScript that expose tools, resources and prompts to Claude, with templates, registration and testing.
anthropics/claude-plugins-official
Explains how to bundle Model Context Protocol servers in a Claude Code plugin, covering config files, stdio, SSE, HTTP and WebSocket server types, and authentication.

Triage fits situations like: tasks that involve MCP servers.
Run `npx skills add PrefectHQ/fastmcp --skill triage -a claude-code`. Or copy the skill folder (.agents/skills/triage in PrefectHQ/fastmcp) into .claude/skills/triage in your project. Claude Code loads it when a task matches its description.
Run `npx skills add PrefectHQ/fastmcp --skill triage -a codex`. Or copy the skill folder (.agents/skills/triage in PrefectHQ/fastmcp) into .agents/skills/triage in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add PrefectHQ/fastmcp --skill triage -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/triage, .gemini/skills/triage, .github/skills/triage and .opencode/skills/triage in your project.
Going by SKILL.md and its folder, Triage needs the command-line tools its instructions call (gh).
SKILL.md contains no URLs. Its commands use gh, which can reach the network depending on how they are called. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Triage is published under the Apache-2.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 573 tokens (SKILL.md is roughly 2.3k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
Skills that share tags, products or a category with Triage: MCP Server Builder (anthropics/skills, 180k stars), MCP Server Builder (shareAI-lab/learn-claude-code, 78k stars), MCP Integration for Plugins (anthropics/claude-plugins-official, 38k stars) and Crush Configuration (charmbracelet/crush, 29k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
