AnthropicSkill

signature-request

anthropics/knowledge-work-plugins/legal/skills/signature-request/SKILL.md

Prepare and route a document for e-signature — run a pre-signature checklist, configure signing order, and send for execution. Use when a contract is finalized and ready to sign, when verifying entity names, exhibits, and signature blocks before sending, or when setting up an envelope with sequential or parallel signers.

dotnetSkill

update-agent-docs

dotnet/roslyn/.github/skills/update-agent-docs/SKILL.md

Assess whether task-relevant agent documentation needs changes in the Roslyn repo. Run at the end of every task that modifies code, adds files, changes public APIs or diagnostics, or establishes new patterns. Keeps .github/memory/ fresh and reliable.

ComposioHQSkill

typescript-providers

ComposioHQ/composio/.agents/skills/typescript-providers/SKILL.md

Implement, modify, test, or document TypeScript provider packages under ts/packages/providers, including framework adapters for OpenAI, Anthropic, Google, LangChain, Mastra, Vercel, LlamaIndex, Cloudflare, Claude Agent SDK, and TypeSafe. Use for provider-specific TS work; do not use for core-only changes.

meteorSkill

sync-modern-tool-versions

meteor/meteor/.github/skills/sync-modern-tool-versions/SKILL.md

Use when changing npm package or dependency versions used by Meteor's modern tooling, especially Rspack and SWC.

AnthropicSkill

runbook

anthropics/knowledge-work-plugins/operations/skills/runbook/SKILL.md

Create or update an operational runbook for a recurring task or procedure. Use when documenting a task that on-call or ops needs to run repeatably, turning tribal knowledge into exact step-by-step commands, adding troubleshooting and rollback steps to an existing procedure, or writing escalation paths for when things go wrong.

genspark-aiSkill

cmux package architecture, refactor layering, dependency inversion, file organization, DocC documentation, package design discipline, testability, and Swift 6 concurrency rules. Use before adding or meaningfully rewriting Swift files, Swift packages, coordinators, services, repositories, or public package APIs.

LangChainSkill

langgraph-docs

langchain-ai/deepagents/libs/code/examples/skills/langgraph-docs/SKILL.md

Fetches and references LangGraph Python documentation to build stateful agents, create multi-agent workflows, and implement human-in-the-loop patterns. Use when the user asks about LangGraph, graph agents, state machines, agent orchestration, LangGraph API, or needs LangGraph implementation guidance.

Fission-AISkill

verify-openspec-docs

Fission-AI/OpenSpec/.agents/skills/verify-openspec-docs/SKILL.md

Fact-checks OpenSpec user documentation with a fresh-context subagent that re-runs commands and checks claims against source. Manually triggered; not part of the drafting loop. Use when the user asks to verify, fact-check, or accuracy-check a docs page, section, or set of changed claims.

gavrielcSkill

add-anydoc

gavrielc/nanoclaw/.claude/skills/add-anydoc/SKILL.md

Add local office-document-to-Markdown conversion to NanoClaw agent containers with the pinned Firecrawl AnyDoc CLI. Use when agents need to read attached Word, PowerPoint, Excel, OpenDocument, RTF, EPUB, CSV, or text-based PDF files without uploading them to a hosted parser.

ace-stepSkill

acestep-docs

ace-step/ACE-Step-1.5/.claude/skills/acestep-docs/SKILL.md

mattpocockSkill

code-review

mattpocock/skills/skills/engineering/code-review/SKILL.md

Review the changes since a fixed point (commit, branch, tag, or merge-base) along two axes: Standards (does the code follow this repo's documented coding standards?) and Spec (does the code match what the originating issue/spec asked for?). Runs both reviews in parallel sub-agents and reports them side by side. Use when the user wants to review a branch, a PR, work-in-progress changes, or asks to \"review since X\".

GitHubSkill

mini-context-graph

github/awesome-copilot/skills/mini-context-graph/SKILL.md

A persistent, compounding knowledge base combining Karpathy's LLM Wiki pattern with a structured knowledge graph. Ingest documents once — the LLM writes wiki pages, extracts entities/relations into the graph, and stores raw content for evidence retrieval. Knowledge accumulates and cross-references; it is never re-derived from scratch.

EveryIncSkill

ce-work

EveryInc/compound-engineering-plugin/skills/ce-work/SKILL.md

Execute a plan or concrete work prompt end-to-end. Use when implementing from a plan document, a spec path, or a clear build request; use ce-debug for open-ended bugs. Use when an outer orchestrator needs implementation and local verification only, without the shipping tail.
