v0.12.0

• Pinned project skills. skills-atlas.json takes optional revisions, a full commit SHA per skill. skills-atlas lock writes them, and lock --dry-run shows the old and new commits with compare links. sync then installs and audits that exact revision and checks every installed copy byte for byte against it. sync --check also reports drifted content.
• sync checks every target agent. A skill installed for Cursor alone no longer satisfies a request for Claude Code. Only the missing skill/agent combinations are installed. -a overrides the file's agents, and -a '*' means every supported agent.
• skills-atlas doctor diagnoses installed skills without changing anything: dangling links, unreadable folders or SKILL.md, a malformed lock file, and lock entries whose skill is gone. Use -p or -g for one scope, and --json for scripts. It exits with 1 when it finds issues.
• Better search. Search ignores case and accents and checks names, descriptions and labels. Every word must match. Name matches rank first, and installs break ties. This applies to the CLI, the tree, the web page, the demo and MCP.
• Web page: details and audit. Details (or p) shows a skill's SKILL.md, its warning signs and any replacements. The changes panel runs the security audit. A skill that fails it is blocked until you tick install anyway for that skill, and Apply audits again before running.
• Web page: retry what failed. After a partial failure or a lost connection, the page keeps only what is still outstanding. Retry remaining changes installs only for the agents that still lack the skill.
• Web page: save as pack. The checked catalog skills become a personal pack in packs.json. It is available right away, and existing packs are never overwritten.
• Catalog health. A snapshot records each source's status. The tree and the web page warn when a source was unavailable during the crawl. Packs show how many of their members are in the catalog and which are missing, in skills-atlas packs too.
