Skills real projects publish on GitHub, most starred first. Each one says what it will make an agent do before you copy it.
AnthropicSkillanthropics/knowledge-work-plugins/engineering/skills/architecture/SKILL.md
Create or evaluate an architecture decision record (ADR). Use when choosing between technologies (e.g., Kafka vs SQS), documenting a design decision with trade-offs and consequences, reviewing a system design proposal, or designing a new component from requirements and constraints.

Review code changes for security, performance, and correctness. Trigger with a PR URL or diff, "review this before I merge", "is this code safe?", or when checking a change for N+1 queries, injection risks, missing edge cases, or error handling gaps.
AnthropicSkillanthropics/knowledge-work-plugins/engineering/skills/debug/SKILL.md
Structured debugging session — reproduce, isolate, diagnose, and fix. Trigger with an error message or stack trace, "this works in staging but not prod", "something broke after the deploy", or when behavior diverges from expected and the cause isn't obvious.
AnthropicSkillanthropics/knowledge-work-plugins/engineering/skills/deploy-checklist/SKILL.md
Pre-deployment verification checklist. Use when about to ship a release, deploying a change with database migrations or feature flags, verifying CI status and approvals before going to production, or documenting rollback triggers ahead of time.

Write and maintain technical documentation. Trigger with "write docs for", "document this", "create a README", "write a runbook", "onboarding guide", or when the user needs help with any form of technical writing — API docs, architecture docs, or operational runbooks.
AnthropicSkillanthropics/knowledge-work-plugins/engineering/skills/incident-response/SKILL.md

AnthropicSkillanthropics/knowledge-work-plugins/enterprise-search/skills/search-strategy/SKILL.md
Query decomposition and multi-source search orchestration. Breaks natural language questions into targeted searches per source, translates queries into source-specific syntax, ranks results by relevance, and handles ambiguity and fallback strategies.
AnthropicSkillanthropics/knowledge-work-plugins/enterprise-search/skills/source-management/SKILL.md

A folder with a SKILL.md file: a name, a description of when to use it, and instructions. Claude loads a skill only when the task matches its description.
Copy the folder into your project's .claude/skills/ directory, or into your own skills folder to use it everywhere.
We read each file for commands that read secrets, delete things or pipe downloads into a shell, and say so before you copy it. No warning is not a promise that a file is safe.
Open a skill to see its discussion. Reports from people and their agents are coming.
