MicrosoftSkill

playwright-triage

microsoft/playwright/.claude/skills/playwright-triage/SKILL.md

Triage and fix one microsoft/playwright issue, or do a maintainer's task, unattended inside the Issue triage GitHub Actions workflow (.github/workflows/triage.yml), which a needs-triage, needs-triage-mac or needs-triage-win label starts, or a maintainer starts by hand with an issue, a task or both. Reproduces the issue on the runner, then leaves a verified fix proposal for the workflow to open as a draft PR, a test that covers a scenario that did not reproduce, an investigation note for it to post on the issue, or a browser bug report for it to file in microsoft/playwright-browsers or for a maintainer to file at crbug.com. Only for that workflow.

playwright-cli

microsoft/playwright/packages/playwright-core/src/tools/skills/playwright-cli/SKILL.md

playwright-component-testing

microsoft/playwright/packages/playwright-core/src/tools/skills/playwright-component-testing/SKILL.md

Set up component testing with Playwright using a story gallery — scaffold stories and a gallery dev page driven by the built-in mount fixture, no dedicated component-testing runtime. Use when asked to test React or Vue components in isolation with Playwright, or to migrate off @playwright/experimental-ct-react / -vue.

MicrosoftSkill

playwright-trace

microsoft/playwright/packages/playwright-core/src/tools/skills/playwright-trace/SKILL.md

Inspect Playwright trace files from the command line — list actions, view requests, console, errors, snapshots and screenshots.

Model Context ProtocolSkill

board-ops

modelcontextprotocol/servers/.claude/skills/board-ops/SKILL.md

gh recipes for the Servers V2 project board (#43): add an issue's card, move its Status, set or change its Priority, delete a card, and recover from a deleted single-select option. Use when moving a card between columns; when setting Status or Priority; when an option ID is rejected; before editing a board field's options; or when cards lost their Status or Priority.

Model Context ProtocolSkill

client-smoke

modelcontextprotocol/servers/.claude/skills/client-smoke/SKILL.md

Drive a locally built server with a real client: the Inspector CLI (scripted), the Inspector web UI (through Playwright) and an LLM client. Use when smoke-testing a server change; when calling a tool, reading a resource or getting a prompt from the command line; when choosing a protocol era; or when the Inspector CLI will not connect to, or misreads, a server command.

Model Context ProtocolSkill

issue-create

modelcontextprotocol/servers/.claude/skills/issue-create/SKILL.md

Create a tracked issue in this repo end to end — duplicate check, v2 label, type label, server-scope label, milestone, board card, Status and Priority. Use when asked to file, create, open or raise an issue; when picking its labels or its milestone; when checking whether one already exists; or when work discovered mid-task needs an issue of its own.

Model Context ProtocolSkill

issue-triage

modelcontextprotocol/servers/.claude/skills/issue-triage/SKILL.md

Triage this repo's inflow — sweep unboarded issues onto the Servers V2 board (#43) as Incoming, score Priority with the rubric and post the score, classify outside PRs and spam (server listings, new servers, duplicates, no-ops) and close them with their canned comments, and run the board audit. Use for \"triage new issues\" or \"triage the PRs\"; when scoring an issue's Priority; when answering or closing an outside PR; or when auditing the board for drift.

Model Context ProtocolSkill

local-dev

modelcontextprotocol/servers/.claude/skills/local-dev/SKILL.md

Install, build and run a server from this checkout. Use when starting a server locally over stdio, SSE or Streamable HTTP; when pointing npx, uvx or an MCP client config at the local build; when a running server still shows old code, or dist is missing; when setting up a git worktree; or when adding an overrides pin.

pre-push-gate

modelcontextprotocol/servers/.claude/skills/pre-push-gate/SKILL.md

Run this repo's pre-push gate and fix it when it goes red. Use when npm run local:gate fails or a stage of it does (verify:install-fresh, a root guard, lint, typecheck, ruff, pyright, pytest, verify:skills:cli, the boot smoke); when the gate says it is waiting on the gate lease; or when checking whether a gate run really passed.

pr-flow

modelcontextprotocol/servers/.claude/skills/pr-flow/SKILL.md

Take an issue through to a PR in this repo and close it out after merge. Use when asked to open, create or submit a PR; when naming a branch; when signing off commits or repairing a missing Signed-off-by; when recording client evidence for a PR; when requesting a Copilot review, answering its comments or deciding whether to run another round; or when closing out after a merge.

Model Context ProtocolSkill

project-structure

modelcontextprotocol/servers/.claude/skills/project-structure/SKILL.md

Find where code lives in this repo's seven servers and decide where a new file goes. Use when choosing the file or directory for a new tool, resource, prompt, transport, helper module, command-line flag or root script; when a server's layout is unclear; or when asking whether code belongs in a server's entry file or a module of its own.

release

modelcontextprotocol/servers/.claude/skills/release/SKILL.md

Cut a milestone release: the release issue, the preparation PRs on v2/main (audit, changesets Version Packages, Python CalVer), the pure v2/main to main merge PR with its release ledger, then the GitHub Release a maintainer publishes.

security-advisory

modelcontextprotocol/servers/.claude/skills/security-advisory/SKILL.md

Take a privately reported vulnerability through this repo's security advisory flow: board it as a draft card, check whether the code is this repo's server or the SDK underneath, accept or reject, fix it in the private fork, release, publish, then turn the card into public tracking. Use when a vulnerability is reported privately; when deciding whether an advisory is ours to fix or belongs to an SDK; when looking up or creating its private fork; when answering a reporter; or when a GHSA-titled board card needs handling.

Model Context ProtocolSkill

testing

modelcontextprotocol/servers/.claude/skills/testing/SKILL.md

Write, place and run tests for a server in this repo. Use when choosing between driving the server through an MCP client and calling its functions directly; when writing a protocol-level test for a TypeScript or Python server; when choosing the command that runs one suite or a coverage report; or when a test is skipped or passes against a stale build.

AstralSkill

load-github-action-thread

astral-sh/uv/.codex/skills/load-github-action-thread/SKILL.md

When given an issue instead of a run, find the related issue-triage run first. Resolve the issue title and number, then match the run display title: Use the newest matching run. An issue-triage run can contain both the triage and bug-reproduction threads. Also check for directly dispatched bug-reproduction runs; their display title does not include the issue title. If the issue title changed or a run was manually dispatched, list recent candidates and confirm them from their logs: When given…
