Agent Tool 0.3.0

Added

• The Dashboard now shows read-only environment diagnostics for broken links, missing SKILL.md files, independent same-name skill copies, and MCP launch commands that are absent from PATH. It never starts configured MCP commands or records diagnostic history.
• The Dashboard now also warns when Claude registers an MCP server with the same name at user and project scope, without guessing which registration takes precedence.
• The Environment section now separates each agent's supported formats, installed formats, and CLI detection state. Cursor is shown as configuration-detected because it has no CLI interface.
• Update previews now summarize added, removed, and changed files, flag manifest/configuration changes, and say when the displayed diff is incomplete.
• Managed, enabled Skills can now be copied between the user profile and the current project. The confirmation shows both paths, never overwrites an existing destination, and leaves the source unchanged.
• Environment and environment-diagnostics details now sit at the bottom of the Dashboard, are left-aligned and collapsed by default, and can be expanded without saving a UI preference.
• The Environment details now show the absolute path of each detected agent CLI.
• Rules are now listed in the Dashboard for both user scope (~/.claude/rules/*.md, ~/.cursor/rules/*.mdc) and project scope (<project>/.claude/rules/*.md, <project>/.cursor/rules/*.mdc), including rules kept in subdirectories. You can delete rules that you or your team placed there; the extension does not add rules from a URL, and enable/disable are not offered because rules load unconditionally or based on their own paths: frontmatter. Codex AGENTS.md and Gemini GEMINI.md are single-file formats and out of scope.

Changed

• Documented Remote (SSH / Dev Container / Codespaces) behavior as read-only listing with all write operations rejected, matching what the extension has always done. Previous wording implied even reading was blocked.
• Added an opt-in Playwright end-to-end script (npm run test:browser) that loads the packaged browser extension into Chromium and asserts the toolbar badge fills in for each supported catalog. Excluded from CI so real-site or catalog outages never break npm test.
• The browser extension now detects catalog skills that live under .agent-skills/<name>/SKILL.md, checked only when the canonical skills/<name>/SKILL.md returns 404. This lets repositories that keep 100+ skills in a hidden directory (measured: akillness/jeo-skills, 140 MB archive) install a single skill without hitting the archive size limit.
• The browser extension now shows a "!" toolbar badge (with a tooltip explaining the cause) when GitHub's unauthenticated rate limit stops it from listing skills at a directory URL. Previously the badge stayed empty, indistinguishable from a directory that has no skills.
