pi-memory-honcho

Honcho-backed persistent memory extension for the PI coding agent. Persistent user context, cross-workspace memory sharing, and dialectic reasoning across sessions.

Forked from acsezen/pi-memory-honcho. Maintained as part of that-yolanda/pi-extensions.

Install

pi install npm:@that-yolanda/pi-memory-honcho

Setup

1. Get a Honcho API key from honcho.dev or self-host.
2. Run /honcho:setup inside PI to configure your key, workspace, and peer names.
3. Verify with /honcho:doctor.

Or create ~/.honcho/config.json manually:

{
  "apiKey": "hch-v3-...",
  "peerName": "yourname",
  "hosts": {
    "pi": {
      "workspace": "pi",
      "aiPeer": "pi",
      "recallMode": "hybrid"
    }
  }
}

Features

Memory tools

| Tool | Description | |------|-------------| | honcho_profile | Retrieve user profile from this and linked workspaces | | honcho_search | Search durable memory across all linked workspaces | | honcho_context | Synthesize memory context via dialectic reasoning across all linked workspaces | | honcho_conclude | Store a durable preference, fact, or decision (primary workspace only) | | honcho_seed_identity | Seed the AI peer's identity representation (primary workspace only) |

Commands

| Command | Description | |---------|-------------| | /honcho:setup | Interactive first-time configuration | | /honcho:status | Show connection, cache, and config status | | /honcho:config | Show effective config (redacted API key) | | /honcho:doctor | Preflight check for config, connectivity, session | | /honcho:interview | Save a preference or working style insight | | /honcho:mode | Switch recall mode (hybrid / context / tools) | | /honcho:sync | Force context refresh and flush pending uploads | | /honcho:map | Map current directory to a custom session name |

Lifecycle

• Session start: Bootstraps Honcho connection, fetches context, migrates legacy memory files (MEMORY.md, USER.md, SOUL.md)
• Before agent start: Injects persistent memory into the system prompt (user profile, peer cards, AI profile, project summary)
• Agent end: Uploads conversation messages to Honcho
• Session shutdown/switch/fork/compact: Flushes pending uploads

Configuration

All fields can be set via ~/.honcho/config.json (under hosts.pi) or environment variables.

Manual session mappings

Add sessions to your ~/.honcho/config.json to map directories to specific session names:

{
  "sessions": {
    "/home/user/project-a": "my-project-a",
    "/home/user/project-b": "my-project-b"
  }
}

Linked hosts

Share memory across AI tools by linking their workspaces. Read tools (honcho_profile, honcho_search, honcho_context) fan out to all linked workspaces and merge results. Write tools (honcho_conclude, honcho_seed_identity) stay in the primary workspace, following Honcho's workspace isolation design.

Linked host SDK clients are created once at startup and cached, not per tool call. Profile reads from linked workspaces use peer.representation() (no reasoning tokens) instead of dialectic calls.

{
  "hosts": {
    "pi": {
      "workspace": "pi",
      "aiPeer": "pi",
      "linkedHosts": ["claude_code", "codex", "cursor"]
    },
    "claude_code": {
      "workspace": "claude_code",
      "aiPeer": "claude"
    },
    "codex": {
      "workspace": "codex",
      "aiPeer": "codex"
    },
    "cursor": {
      "workspace": "cursor",
      "aiPeer": "cursor"
    }
  }
}

Each linked host must have workspace and aiPeer defined. Results are labeled by source workspace (e.g., === [cursor] ===).
