GitHubSkilldependency-scanning
github/copilot-advanced-security-plugin/skills/dependency-scanning/SKILL.md

GitHubSkillspeckit-artifact
github/spec-kit-copilot/skills/speckit-artifact/SKILL.md
Inspect the effective Spec Kit artifact inventory and composition stacks via `specify artifact`. USE FOR: listing commands/templates/scripts/hooks, explaining which preset or extension layer supplies an artifact, inspecting resolution precedence and hidden layers, checking hook registration, or resolving a stack lookupId to its validated contribution. DO NOT USE FOR: installing or changing presets/extensions (use speckit-preset or speckit-extension), resolving only a preset-managed filename (use speckit-preset), or running an artifact.
GitHubSkillspeckit-bundle
github/spec-kit-copilot/skills/speckit-bundle/SKILL.md
Discover, install, and author Spec Kit bundles via `specify bundle`. USE FOR: searching/showing/listing bundles, installing/updating/removing a bundle (a curated set of extensions/presets/integrations/workflows), validating a bundle manifest, building a distributable bundle artifact, initializing a project and installing a bundle, managing bundle catalog sources. DO NOT USE FOR: individual extensions/presets/integrations/workflows (use their respective skills).
GitHubSkillspeckit-check
github/spec-kit-copilot/skills/speckit-check/SKILL.md
Check the local environment for Spec Kit by running `specify check` (and `specify version`). USE FOR: verifying required tools are installed, diagnosing a broken spec-kit setup, reporting CLI version/feature capabilities. DO NOT USE FOR: installing or upgrading the CLI itself (use the speckit-self skill).
GitHubSkillspeckit-cli-setup
github/spec-kit-copilot/skills/speckit-cli-setup/SKILL.md
Detect and install the Spec Kit `specify` CLI that every other speckit skill depends on. USE FOR: checking whether `specify` is installed/on PATH, installing it when missing, fixing "command not found: specify", confirming the CLI is new enough (>= 0.11). DO NOT USE FOR: upgrading an already-installed CLI to a newer release (use speckit-self) or verifying project tools (use speckit-check).
GitHubSkillspeckit-extension
github/spec-kit-copilot/skills/speckit-extension/SKILL.md
Manage Spec Kit extensions via `specify extension`. USE FOR: listing installed extensions as text or JSON, installing/removing/updating extensions, searching the extension catalog, showing extension info, enabling/disabling extensions, setting resolution priority, or managing extension catalogs. DO NOT USE FOR: artifact composition stacks (use speckit-artifact), presets (use speckit-preset), bundles (use speckit-bundle), or workflows (use speckit-workflow).
GitHubSkillspeckit-init
github/spec-kit-copilot/skills/speckit-init/SKILL.md
Scaffold a Spec Kit (spec-driven development) project for GitHub Copilot by running `specify init --integration copilot --integration-options="--skills"`. USE FOR: starting a new spec-kit project, bootstrapping spec-driven development in an existing repo, installing spec-kit templates/scripts/commands for Copilot. DO NOT USE FOR: managing extensions/presets/bundles of an already-initialized project (use the speckit-extension / speckit-preset / speckit-bundle skills instead).
GitHubSkillspeckit-preset
github/spec-kit-copilot/skills/speckit-preset/SKILL.md
Manage Spec Kit presets via `specify preset`. USE FOR: listing installed presets as text or JSON, installing/removing presets, searching the preset catalog, showing preset info, resolving which template a preset name maps to, enabling/disabling presets, setting resolution priority, or managing preset catalogs. DO NOT USE FOR: full artifact composition stacks (use speckit-artifact), extensions (use speckit-extension), bundles (use speckit-bundle), or workflows (use speckit-workflow).
GitHubSkillspeckit-self
github/spec-kit-copilot/skills/speckit-self/SKILL.md
Check for and apply Spec Kit CLI updates via `specify self`. USE FOR: checking whether a newer specify-cli release is available, previewing an upgrade with --dry-run, upgrading the CLI in place (optionally to a pinned tag). DO NOT USE FOR: checking project tools/integrations (use speckit-check) or managing extensions/presets/integrations/workflows.
GitHubSkillspeckit-workflow
github/spec-kit-copilot/skills/speckit-workflow/SKILL.md
Manage and run Spec Kit automation workflows via `specify workflow`. USE FOR: running a workflow by ID or local YAML, resuming a paused/failed run, checking run status, listing/installing/removing workflows, searching the workflow catalog, showing a workflow step graph. DO NOT USE FOR: extensions (use speckit-extension), presets (use speckit-preset), or bundles (use speckit-bundle).

About skills
What is a Claude skill?
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.
How do I use one I find here?
Copy the folder into your project's .claude/skills/ directory, or into your own skills folder to use it everywhere.
What do the warnings mean?
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.
Which skills worked for people?
Open a skill to see its discussion. Reports from people and their agents are coming.
