Changelog

All notable changes to the Contentstack agent skills bundle. Versions match the version field in every plugin manifest that declares one.

0.2.0

Install anywhere, from one source

• Every skill now lives once in skills/<slug>/SKILL.md (Agent Skills format), and every supported tool reads that folder directly.
• New and updated plugin manifests: Claude Code, claude.ai and Cowork (.claude-plugin/), Codex (plugin.json, .agents/plugins/marketplace.json), Cursor (.cursor-plugin/), GitHub Copilot (reads .claude-plugin/ and plugin.json) and Gemini CLI (gemini-extension.json).
• The marketplace plugin source is now "./", so the repo syncs on claude.ai and Cowork.
• The README has real install commands for every tool, and a new docs/ site covers install, architecture, contributing and every skill.

New skills

• dx-kickstart-next: building, reviewing and debugging Contentstack's Next.js kickstart.
• studio: Contentstack Studio end to end, routed to bundled specialist guides. studio ships as a preview; some guides are still being reconciled with the Studio team.

Changed skills

• Live Preview support is rebuilt as a seven-step diagnostic protocol covering Live Preview, Visual Editor and Timeline, with twelve reference files.
• migration-companion is leaner. Its SKILL.md went from 959 to about 340 lines; per-step detail now lives in references/step-*.md and loads only when that step runs.
• Security review: token handling, TLS, frame headers and confirmation steps tightened across skills. migration-companion resolves its Contentful token without printing it, logs to the session directory by default, and discloses that its prerequisite check may install or upgrade global CLIs.
• Better automatic triggering. Every skill's description now says when to use it, so agents can pick the right skill without a separate router file.

Breaking changes

• Removed cursor/rules/ and codex/. If you copied those folders by hand, remove them and install with the Cursor or Codex instructions in the README.
• Renamed cms-live-preview-visual-builder-support-assistant → cms-live-preview-visual-editor-support-assistant.
• Skill names now match their folders: contentstack-migration-companion → migration-companion.
• Removed skills/CLAUDE.md (the router) and manifest.json.

Contributors

• Validation in CI: node scripts/validate.mjs checks that each skill's name matches its folder and follows the naming rules; that its description exists, is at most 1024 characters and includes "Use when"; that SKILL.md has a ## Security section with ### Defaults, ### Destructive Actions, ### Secrets and ### Environment Variables; that relative links in every Markdown file under skills/ resolve and stay inside the skill folder; that frontmatter values containing : in skills/ and docs/ are quoted; and that the manifests parse and every versioned manifest carries the same version. It replaces the build-and-commit workflow and runs on pull requests to any branch, pushes to main and next, and manual dispatch.
• Releases: bump version in every manifest and add an entry here.

0.1.0

Initial bundle of 21 skills.
