ctx-purge

Context Mode Purge

Permanently deletes ALL session data for this project: knowledge base, session events, analytics, and stats.

Instructions

1. Warn the user: This is irreversible. Everything will be deleted:
   • FTS5 knowledge base (all indexed content from ctx_index, ctx_fetch_and_index, ctx_batch_execute)
   • Session events DB (analytics, metadata, resume snapshots)
   • Session events markdown file
   • In-memory session stats
2. Call the mcp__context-mode__ctx_purge MCP tool with confirm: true.
3. Report the result to the user — the response lists exactly what was deleted.

When to Use

• When the KB contains stale or incorrect content polluting search results.
• When switching between unrelated projects in the same session.
• When you want a completely fresh start for this project.

Important

• ctx_purge is the only way to delete session data. No other mechanism exists.
• ctx_stats is read-only — shows statistics only.
• /clear and /compact do NOT affect any context-mode data.
• There is no undo. Re-index content if you need it again.
