Plugin marketplace catalog for stackhawk/agent-skills.

This is an open-source, publicly installable catalog. It holds only the catalogs that control which version of agent-skills marketplace consumers install — each plugin pinned to a tested GA release (ref + sha). Bumping the pin here rolls out updates on StackHawk's release cadence, independently of the plugin development cadence.

The catalog publishes two plugins: hawkscan (DAST scanning) and stackhawk-api (StackHawk platform API).

Install

The marketplace serves the agents whose plugin systems can pin a remote source. Pick yours:

Claude Code

/plugin marketplace add stackhawk/agent-skills-marketplace
/plugin install hawkscan@stackhawk
/plugin install stackhawk-api@stackhawk

Codex

codex plugin marketplace add stackhawk/agent-skills-marketplace
codex plugin add hawkscan@stackhawk
codex plugin add stackhawk-api@stackhawk

GitHub Copilot CLI

copilot plugin marketplace add stackhawk/agent-skills-marketplace
copilot plugin install hawkscan@stackhawk
copilot plugin install stackhawk-api@stackhawk

> Cursor and Antigravity (agy) don't consume this marketplace — they install directly from stackhawk/agent-skills (Cursor copies the generated .mdc rules; agy plugin install <agent-skills repo URL>). See the agent-skills README for their steps.

Structure

.claude-plugin/marketplace.json   # Claude Code + GitHub Copilot CLI — github source + path
.agents/plugins/marketplace.json  # Codex — git-subdir source
.codex-plugin/marketplace.json    # legacy Codex path (back-compat)

Every plugin entry points at stackhawk/agent-skills at a subdirectory (plugins/<name>), pinned to a release ref + sha. The per-tool source schema differs (Claude/Copilot use a github source; Codex uses git-subdir), which is why there is more than one catalog.

Updating the pinned version

These catalogs are generated, not hand-edited. When agent-skills cuts a release, its release.yml runs scripts/generate-marketplace-catalogs.py and pushes the regenerated catalogs here automatically — pinning every plugin to the new tag + SHA in each tool's schema. To roll a new version out to consumers, release agent-skills; don't edit marketplace.json by hand (a release will overwrite it).

Why a separate repo

• agent-skills iterates continuously; this repo only changes when we deliberately roll a GA version to consumers
• SHA pinning alongside ref guarantees reproducibility even if a tag is moved
• Public and open source so any supported agent can install StackHawk skills directly

Contributing

The catalogs are generated from stackhawk/agent-skills — to add or change skills, contribute there. The generator and publisher live in that repo (scripts/generate-marketplace-catalogs.py and .github/workflows/release.yml).
