Agent Brain v2.0.0

Agent Brain v2 keeps the original vault and 15 workflows while removing runtime drift.

What changed

• .agents/skills is the canonical workflow source
• bun run sync materializes portable Claude Code skill and slash command adapters
• bun run check rejects stale adapters, invalid frontmatter, missing workflows, and mirrored template drift
• the original slash commands and seven-folder vault remain compatible
• the v1 migration copies workflow surfaces without replacing personal notes or context
• setup and command documentation now match the files that actually ship

Upgrade from v1

Follow the non-destructive migration guide. The original release remains available as v1.0.0.

Verification

The release passed the template checker, review surface gates, a temporary migration from v1, and a forced stale-adapter failure. Read the v2 review evidence.
