n8n:create-instance-ai-eval

n8n-io/n8n/.agents/skills/create-instance-ai-eval/SKILL.md

Authors a new Instance AI workflow or Agent eval case — written locally as JSON, calibrated against a real build, then pushed to the LangTracer suite CI runs — build cases, behaviour/process cases, credential cases, and seeded (mid-conversation) cases — with intent-driven expectations. Use when adding or changing an Instance AI eval, or debugging why one is flaky.

MicrosoftSkill

experiments

microsoft/vscode/.github/skills/experiments/SKILL.md

Use when adding, changing, or reviewing a VS Code A/B experiment, either an experiment-controlled setting or a treatment read with the assignment service, and when deciding whether and where to log an `experimentTrigger` event for a triggered ExP scorecard.

MicrosoftSkill

integrated-browser

microsoft/vscode/.github/skills/integrated-browser/SKILL.md

Use this when working on the VS Code integrated browser ("browserView") to understand its architecture and mental model. Covers the embedded Chromium browser, its editor tab, navigation, overlay/layout, sessions, and agent browser tools under `src/vs/platform/browserView` and `src/vs/workbench/contrib/browserView`.

MicrosoftSkill

policy-and-managed-settings

microsoft/vscode/.github/skills/policy-and-managed-settings/SKILL.md

Use whenever adding, modifying, or reviewing any Copilot, agent, LLM, AI, tool, permission, sandbox, MCP, model, telemetry, feature-gate, setting, configuration, or enterprise control—especially anything an organization or administrator may need to manage. Start here to decide whether it belongs in runtime managed settings, a typed SDK contract, VS Code configuration policy, extension policy, or a split implementation. Run on every new Copilot/agent/LLM control and ANY change that adds a `policy:` field.

MicrosoftSkill

sweeper-implement

microsoft/vscode/.github/skills/sweeper-implement/SKILL.md

Implement a VS Code Sweeper agent-ready issue — fetch the sweeper's review record from its state repo, implement the change in the current vscode checkout from the review's brief (an implement-ready record) or from an approved sweeper-plan file, validate the diff against it, and — after the maintainer has reviewed the changes in their editor — open a draft PR. Use ONLY when the request explicitly asks for the sweeper — "sweeper-implement", "sweeper", "vscodesweeper", a sweeper record, an agent-ready issue, or a sweeper brief — or asks to implement a sweeper plan ("implement plan <n>", a `.sweeper/plans/issue-<n>.md` file). Do NOT use for a plain "fix this issue" request that doesn't mention the sweeper; fix those directly with your normal tools instead.

MicrosoftSkill

sweeper-plan

microsoft/vscode/.github/skills/sweeper-plan/SKILL.md

Plan a VS Code Sweeper agent-ready issue with the maintainer — fetch the sweeper's review record from its state repo, put the review's open decisions to the maintainer, and write a plan file (.sweeper/plans/issue-<n>.md) for them to edit in their editor; it writes no code and ends there — the sweeper-implement skill implements the approved plan. Use ONLY when the request explicitly asks for the sweeper plan — "sweeper-plan", "plan … with the sweeper", a sweeper record or agent-ready issue to plan first. Do NOT use for a plain planning request that doesn't mention the sweeper.

MicrosoftSkill

sweeper-query

microsoft/vscode/.github/skills/sweeper-query/SKILL.md

Answer natural-language questions about the VS Code Sweeper's published issue index (index-<name>.json for microsoft/vscode and the enrolled family repos) — which issues are agent-ready to implement or plan, what the sweeper proposed for an assignee or area, whether the sweeper knows a report as a duplicate, the highest-value open bugs in a lane — and, for one issue, the review's full record (evidence with file citations, fix brief, proposed comment). Use ONLY when the request explicitly names the sweeper — "sweeper", "vscodesweeper", "sweeper-query", a sweeper verdict, record, brief or index, an agent-ready issue — or asks what "the sweeper" found, proposed or knows. Do NOT use for general questions about issues, duplicates, priorities or ranking that do not mention the sweeper. Read-only; discovery only.

claude-api

anthropics/skills/skills/claude-api/SKILL.md

Reference for the Claude API / Anthropic SDK — model ids, pricing, params, streaming, tool use, MCP, agents, caching, token counting, model migration. TRIGGER — read BEFORE opening the target file; don't skip because it "looks like a one-liner" — whenever: the prompt names Claude/Anthropic in any form (Claude, Anthropic, Fable, Opus, Sonnet, Haiku, `anthropic`, `@anthropic-ai`, `claude-*`, `us.anthropic.*`, `[1m]`); the user asks about an LLM (pricing/model choice/limits/caching) — never answer from memory; OR the task is LLM-shaped with provider unstated (agent/MCP/tool-definition/multi-agent/RAG/LLM-judge/computer-use; generate/summarize/extract/classify/rewrite/converse over NL; debugging refusals/cutoffs/streaming/tool-calls/tokens). SKIP only when another provider is being worked on (overrides all triggers): OpenAI/GPT/Gemini/Llama/Mistral/Cohere/Ollama named in the query; OR `grep -rE 'openai|langchain_openai|google.generativeai|genai|mistralai|cohere|ollama'` over the project hits (run this grep FIRST if no provider named — don't Read the file).

discernment-nudge

anthropics/skills/skills/discernment-nudge/SKILL.md

After you give a substantive answer or draft that the user may act on — advice or recommendations, drafted artifacts such as goals, plans, pitches, proposals, or emails, estimates or projections, analysis or interpretation of data, factual claims they may rely on, or a multi-step argument — invoke this skill BEFORE finalizing your reply and then, if it applies, append 2-3 short follow-up questions, each tied to something specific in what you just produced, that help the user check key facts, probe the reasoning or assumptions, and notice missing context. Do this at most once per conversation. Skip it when the user asked a trivial how-to or simple lookup, wants a purely educational explanation, asked you only to format, convert, or assemble a file from content they provided, is writing code they will run, is doing creative writing or casual chat, or already asked you to double-check, cite, or review — the skill file explains these boundaries and the exact output format.

mcp-builder

anthropics/skills/skills/mcp-builder/SKILL.md

Guide for creating high-quality MCP (Model Context Protocol) servers that enable LLMs to interact with external services through well-designed tools. Use when building MCP servers to integrate external APIs or services, whether in Python (FastMCP) or Node/TypeScript (MCP SDK).

skill-creator

anthropics/skills/skills/skill-creator/SKILL.md

Create new skills, modify and improve existing skills, and measure skill performance. Use when users want to create a skill from scratch, edit, or optimize an existing skill, run evals to test a skill, benchmark skill performance with variance analysis, or optimize a skill's description for better triggering accuracy.
