What changed

• plugins/agent-commerce-gateway/.cursor-plugin/plugin.json: a Cursor plugin manifest for the existing plugin folder. Same name, display name, description, version and license as the Claude Code manifest; skills points at the same skills/ folder, and logo reuses .claude-plugin/icon.png.
• .cursor-plugin/marketplace.json: lists the plugin from ./plugins/agent-commerce-gateway, the same source as .claude-plugin/marketplace.json.
• tests/unit/cli/skill.test.ts: checks that the Cursor manifest has the package version and license, matches the Claude Code manifest, is listed from the plugin folder, and uses relative paths to files that exist.
• scripts/check-package-metadata.mjs: also checks repository and homepage in the Cursor manifest.
• plugins/agent-commerce-gateway/README.md: "helps Claude" and "tells Claude" become "helps a coding agent" and "tells the agent".

The skill files are unchanged.

Why

Cursor reads a plugin from .cursor-plugin/plugin.json and finds it in a repository through .cursor-plugin/marketplace.json at the root (plugins reference). With both files in place, the repository can be submitted to the Cursor Marketplace (cursor.com/marketplace/publish) and to cursor.directory.

Cursor's manifest schema rejects unknown fields, so the Claude-only fields (documentationUrl, supportUrl, privacyPolicyUrl, termsOfServiceUrl) are not copied.

Release note

Each release now bumps version in both plugin manifests. The new test fails if .cursor-plugin/plugin.json is left behind.

How it was tested

On Node 22.23.2 after npm ci:

• Both manifests validate against Cursor's published schemas (schemas/ in cursor/plugins @ bf0c7cd), with the same checks as their scripts/validate-plugins.mjs: names match, manifest versions match, paths are relative and exist. A copy with an unknown field, a different version and a .. logo path fails all three.
• npx vitest run tests/unit/cli/skill.test.ts: 13 passed. With the Cursor version set to 2.7.1, the version test fails.
• npm run check:contract, npm run lint, npm run typecheck, node scripts/check-package-metadata.mjs: OK.
• claude plugin validate ./plugins/agent-commerce-gateway and claude plugin validate .: pass. The only warnings are the four listing fields in .claude-plugin/plugin.json (documentationUrl, supportUrl, privacyPolicyUrl, termsOfServiceUrl), which this PR does not change.
• npm run test:coverage: 3880 passed, 5 failed, 6 skipped. Three failures were packaging.test.ts against a stale local dist; after npm run build that file passes (37). The other two are the macOS-only gateway-entrypoint failures (bash 3.2 has no mapfile), which fail the same way on master.

Not covered

• Not loaded in Cursor itself yet. Cursor's submission checklist asks for a local test before submitting, so that comes before the marketplace submission.
• Not run: npx skills add against this branch. The skill path is unchanged.
