Problem

The Honcho memory plugin exposes a honcho_conclude(delete_id=...) tool to delete conclusions for PII removal, but no tool exposes conclusion IDs. Users (and the agent itself) cannot determine the delete_id to pass.

In practice, agents accumulate test/debug conclusions during interactive debugging that they cannot clean up. The agent reports "Impossible to recover ID for delete_id" because all read-side tools (honcho_search, honcho_profile, honcho_reasoning, honcho_context) return aggregated/synthesized text without underlying document IDs.

Solution

Adds a new honcho_list_conclusions tool that returns conclusions with their metadata (id, content, observer, observed, session_id, created_at) using the Honcho SDK's existing peer.conclusions.list() and peer.conclusions.query() APIs.

Changes

plugins/memory/honcho/__init__.py (+27 lines)

• New LIST_CONCLUSIONS_SCHEMA tool definition with query, limit, peer params
• Added to ALL_TOOL_SCHEMAS
• New handler in handle_tool_call calling self._manager.list_conclusions(...)

plugins/memory/honcho/session.py (+56 lines)

• New list_conclusions(session_key, query, limit, peer) method on HonchoSessionManager
• Reuses the same peer/scope resolution logic as delete_conclusion for consistency
• Returns list[dict] with id, content, observer, observed, session_id, created_at

Behavior

• query=None → peer.conclusions.list() (most recent)
• query="..." → peer.conclusions.query(query=...) (semantic search)
• limit clamped to [1, 100]
• Same peer alias resolution as other Honcho tools (user, ai, or explicit ID)
• Same _ai_observe_others flag handling as delete_conclusion

Use case

1. Agent runs honcho_list_conclusions(query="test") → gets [{id: "abc123", content: "..."}]
2. Agent runs honcho_conclude(delete_id="abc123") → conclusion deleted

Testing

Verified end-to-end on Honcho self-hosted v3.0.6 + honcho-ai SDK 2.1.1:

• list() returns conclusions with IDs
• query() returns ranked subset with IDs
• delete_id flow works after listing
• Tool count goes from 5 to 6
• Existing tools unchanged
