Agent Skills

Agent Skills

An index and topic collection covering Agent Skills, the packaged, file-based capability units that AI coding agents load to extend their behavior. Agent Skills bundle instructions, scripts, schemas, and reference material into directories that agents discover, plan against, and execute at runtime, giving organizations a portable way to govern how AI assistants interact with their products and APIs. This collection tracks vendor-published skill repositories (Claude Code skills, Claude Agent SDK skills, Cursor rules, OpenAI Apps SDK skills, and capability packages) shipped by API providers across developer tools, data platforms, SaaS, and infrastructure.

extensionCommon Features

extensionFile-Based Capability Packaging

Agent Skills bundle markdown instructions, executable scripts, schemas, and reference material into versioned directories that agents can load deterministically at runtime.

extensionVendor-Published Skill Repositories

API providers ship official GitHub repositories such as resend-skills, ngrok/agent-skills, postman-skills, and jfrog-skills to deliver first-party automation behavior for their products.

extensionProgressive Disclosure of Context

Skills surface a short SKILL.md frontmatter for discovery, then load deeper instructions, scripts, and assets only when an agent activates them, keeping token usage low.

extensionAgent-Executable Tooling

Skills package shell, Python, or Node scripts alongside instructions so agents can perform multi-step work (auth, file generation, API calls) instead of relying on prose-only prompting.

extensionMulti-Runtime Compatibility

Skill formats are emerging across Claude Code, Claude Agent SDK, Cursor, OpenAI Apps SDK, and Gemini, with vendors publishing parallel skill sets for each runtime.

extensionSkill Discovery and Governance

Organizations curate skill catalogs, sign skill manifests, and gate skill activation through allow lists so AI agents only run vetted capability packages.

extensionAPI-First Skill Generation

Skills are increasingly generated from OpenAPI, AsyncAPI, and APIs.json descriptions so each API operation becomes a callable, governed capability inside an agent.

extensionOpen Skill Ecosystem

A growing ecosystem of community-maintained skill registries and indexes complements vendor repos, mirroring how the npm and PyPI ecosystems formed around packages.

task_altUse Cases

task_altFirst-Party Product Skills

SaaS vendors ship official skill repos so AI agents in Claude Code or Cursor can create resources, run reports, and operate their products without bespoke prompt engineering.

task_altInternal Developer Platform Skills

Platform teams package their CI/CD, deployment, and observability workflows as governed skills so every engineering agent uses the same approved automations.

task_altAPI Onboarding and Education

API providers use skills to walk agents through authentication, sandbox setup, and "hello world" requests, accelerating time-to-first-call for developer-led agents.

task_altGoverned Capability Distribution

Compliance-sensitive organizations distribute skills with allow-lists, signing, and audit trails to ensure only approved AI behaviors run against production systems.

task_altAPI Specification to Skill Pipelines

Teams convert OpenAPI specs into skill bundles (one operation per tool) so agents get typed, governed access to every endpoint without writing custom wrappers.

task_altCross-Runtime Skill Portability

Vendors maintain mirror skill sets for Claude, Cursor, and OpenAI Apps SDK, giving customers a consistent experience across whichever coding agent they choose.

task_altSkill-Driven Customer Support

Support and DevRel teams publish skills that diagnose common issues, pull logs, and open tickets, letting customer-side agents resolve problems autonomously.

task_altSandbox and Test Environment Skills

Skill bundles provision throwaway environments, seed test data, and tear down resources so agents can exercise APIs safely during development and CI.

integration_instructionsIntegrations

integration_instructionsClaude Code

Anthropic's official coding agent loads skills from the .claude/skills directory and surfaces them as plan-then-execute capabilities.

integration_instructionsClaude Agent SDK

The Claude Agent SDK lets developers embed skill loading and execution into their own agent harnesses with the same SKILL.md contract as Claude Code.

integration_instructionsCursor

Cursor consumes vendor rules and skill-style instruction bundles to extend its in-editor coding agent with provider-specific behavior.

integration_instructionsOpenAI Apps SDK

The OpenAI Apps SDK provides a skill-equivalent surface so apps and agents on the OpenAI platform can ship packaged capabilities to ChatGPT and developer tools.

integration_instructionsGoogle Gemini

Gemini's GEMINI.md and skill-style instruction files let vendors target Google's coding agent surface alongside Claude and Cursor.

integration_instructionsGitHub

GitHub hosts the canonical distribution channel for skill repositories, including vendor-published agent-skills, claude-skills, and *-skills repos.

integration_instructionsPostman

Postman's skill repository ships first-party capabilities for working with Postman collections, workspaces, and the Postman API from coding agents.

integration_instructionsAnthropic

Anthropic publishes the SKILL.md format, reference skill repositories, and the Skills feature in Claude Code that anchors the broader ecosystem.
