changelog

Compare the current Claude Code ecosystem against a previous baseline snapshot (from `/moltbloat:snapshot`). Shows what plugins, MCPs, skills, agents, and rules were added, removed, upgraded, or downgraded since the last snapshot. Fully dynamic — no curated opinion lists.

<Use_When>

• User says "changelog", "what changed", "diff", "what's new", "what's different"
• After a Claude Code version upgrade
• After installing or removing plugins
• To understand ecosystem drift over time </Use_When>

<Do_Not_Use_When>

• User wants a full audit with health scoring — use /moltbloat:audit
• User wants to see what a specific plugin does — use /moltbloat:why
• No baseline exists yet — direct user to run /moltbloat:snapshot first </Do_Not_Use_When>

1. Load the baseline snapshot

   cat ~/.moltbloat/baseline.json 2>/dev/null
   

   If no baseline exists, tell the user:

   No baseline snapshot found. Run /moltbloat:snapshot to save the current state, then run /moltbloat:changelog after your next change to see a diff.

   Stop here if no baseline.

2. Collect current state

   Run these scans in parallel:

   Plugins:

   cat ~/.claude/plugins/installed_plugins.json 2>/dev/null
   

   Claude Code version:

   claude --version 2>/dev/null || echo "unknown"
   

   MCP servers: Scan settings.json + plugin .mcp.json files.

   Skills: Count per plugin from cache directories.

   Agents: List from ~/.claude/agents/ and plugin cache.

   Rules: List from ~/.claude/rules/.

3. Diff current vs baseline

   Compare each category:

   Plugins:

   • Added: in current but not in baseline
   • Removed: in baseline but not in current
   • Upgraded: same plugin, higher version
   • Downgraded: same plugin, lower version

   MCP servers:

   • Added/removed MCP server names

   Skills:

   • Net change in skill count per plugin
   • New skill names not in baseline
   • Removed skill names from baseline

   Agents:

   • Added/removed agent files

   Rules:

   • Added/removed rule files or directories

   Claude Code version:

   • Version change (upgrade/downgrade/same)
