Honcho Extension for oh-my-pi

Add AI-native memory to oh-my-pi

English | 中文

Give oh-my-pi long-term memory that survives context wipes, session restarts, and fresh chats. Honcho remembers what you're working on, durable preferences, and prior context across your projects.

Quick Start

Step 1: Get Your Honcho API Key

1. Go to app.honcho.dev
2. Sign up or log in
3. Copy your API key

Step 2: Install the Extension

Install the plugin directly from npm using the omp CLI:

omp install @citywalki/oh-my-pi-honcho-memory

To install it only for the current project:

omp install -l @citywalki/oh-my-pi-honcho-memory

oh-my-pi will discover the extension automatically on next startup.

Step 3: Configure

Create ~/.honcho/config.json:

{
  "apiKey": "hch-...",
  "peerName": "zhangsan",
  "hosts": {
    "omp": {
      "workspace": "fa-dev",
      "aiPeer": "oh-my-pi"
    }
  },
  "sessionStrategy": "per-directory"
}

Step 4: Verify

1. Start oh-my-pi
2. Run /honcho-status to verify the runtime

What You Get

• Persistent Memory - oh-my-pi can retain durable context across sessions
• Cloud or Local Deployments - Use Honcho Cloud or point at a self-hosted or local Honcho instance
• Workspace Mapping - A shared Honcho workspace holds your team or organization
• Developer Voice Isolation - Each developer's observations are captured under their own peer
• Git Awareness - Detect branch switches and external commits between sessions
• Session Mapping - Sessions can be scoped per directory, git branch, or chat instance
• Durable Writes - Save explicit developer observations and conclusions
• Memory Retrieval - Search memory, query Honcho knowledge, and inject relevant context into prompts

Configuration

Configuration is resolved from three sources, later sources overriding earlier ones:

1. Defaults (built-in)
2. Global: ~/.honcho/config.json
3. Environment variables (highest precedence)

Dedicated Config File

You can place a separate config file in any directory. The extension searches upward from the current working directory for the nearest match.

Supported file names (checked in order):

• .honcho-memory.json / .honcho-memory.yml / .honcho-memory.yaml
• honcho-memory.config.json / honcho-memory.config.yml / honcho-memory.config.yaml

To use a custom file name, set HONCHO_MEMORY_CONFIG=acp.json.

{
  "enabled": true,
  "apiKey": "hch-...",
  "workspace": "fa-dev",
  "aiPeer": "oh-my-pi",
  "peerName": "zhangsan",
  "sessionStrategy": "per-directory",
  "sessionPeerPrefix": true,
  "saveMessages": true,
  "reasoningLevel": "low",
  "endpoint": { "environment": "production" },
  "messageUpload": {
    "maxUserTokens": null,
    "maxAssistantTokens": null,
    "summarizeAssistant": false
  },
  "contextTokens": 1200
}

Keys are flat — no honcho: wrapper needed. (If present, a top-level honcho key is also recognized for compatibility.) YAML works the same way.

Dedicated Config File (Recommended)

Create ~/.honcho/config.json:

{
  "apiKey": "hch-...",
  "peerName": "zhangsan",
  "sessionStrategy": "per-directory",
  "sessionPeerPrefix": true,
  "saveMessages": true,
  "endpoint": { "environment": "production" },
  "hosts": {
    "omp": {
      "workspace": "fa-dev",
      "aiPeer": "oh-my-pi"
    }
  }
}

Keys are flat — no honcho: wrapper needed. This is the same format used by the official claude-honcho plugin, so you can share one config file across tools.

Per-Directory Overrides

Use the directories block to apply different settings per project (longest prefix match wins):

{
  "apiKey": "hch-...",
  "hosts": {
    "omp": {
      "workspace": "default-ws",
      "aiPeer": "oh-my-pi"
    }
  },
  "directories": {
    "/Users/me/work/project-a": {
      "apiKey": "hch-company-key...",
      "workspace": "company-ws"
    },
    "/Users/me/work/project-b": {
      "apiKey": "hch-personal-key...",
      "workspace": "personal-ws",
      "sessionStrategy": "git-branch"
    }
  }
}

Environment Variables

Variable	Purpose
HONCHO_API_KEY	Honcho API key
HONCHO_URL	Honcho endpoint (overrides endpoint.baseUrl)
HONCHO_WORKSPACE	Workspace ID
HONCHO_PEER_NAME	Developer peer name
HONCHO_AI_PEER	AI peer name
HONCHO_MEMORY_CONFIG	Override dedicated config file path

Endpoint

Use endpoint.environment for well-known endpoints, or endpoint.baseUrl for a custom URL:

{
  "endpoint": { "environment": "local" }
}

environment values: production (default, https://api.honcho.dev) or local (http://127.0.0.1:8000).

HONCHO_URL still works and takes precedence over endpoint.

Session Strategies

Strategy	Behavior	Best for
per-directory (default)	One session per working directory, named {peerName}-{repoName}	Default project memory
git-branch	Session name includes the current git branch, e.g. {peerName}-{repoName}-{branch}	Feature-branch workflows
chat-instance	Each oh-my-pi chat gets its own session, e.g. {peerName}-chat-{sessionId}	Short-lived isolated work

Session names are prefixed with your peerName by default. Set sessionPeerPrefix: false if you are the only user and want shorter names.

You can override the per-directory session name for specific directories with the sessions map:

{
  "sessions": {
    "/Users/me/work/project-a": "alice-custom-a"
  }
}

Identity Model

Everything in Honcho is a peer:

workspace: fa-dev
├── peer: user-zhangsan
├── peer: user-lisi
└── peer: ai-oh-my-pi

• user-{developer} - captures each developer's voice and observations
• ai-oh-my-pi - the assistant identity that observes and reasons

Conversational turns are automatically saved under the current user-{developer} peer.

Commands

Command	Description
/honcho-status	Show effective Honcho status for the current oh-my-pi project, including live workspace and session names

Tools

The extension exposes these tools inside oh-my-pi:

| Tool | Description | | honcho_search | Search Honcho session messages across developer peers | | honcho_get_context | Retrieve stable memory context for the developer or AI peer | | honcho_get_representation | Retrieve the developer or AI peer's representation string | | honcho_chat | Query Honcho for reasoning-backed context | | honcho_list_conclusions | List durable conclusions stored for the developer peer | | honcho_add_conclusion | Save a durable memory conclusion to the developer peer | | honcho_remember | Alias for honcho_add_conclusion | | honcho_delete_conclusion | Delete a durable conclusion by ID | | honcho_get_config | View current Honcho configuration and connection status | | honcho_set_config | Update a Honcho configuration field in ~/.honcho/config.json |

Development

For developing or debugging this extension locally:

git clone https://github.com/citywalki/oh-my-pi-honcho-memory.git
cd oh-my-pi-honcho-memory
bun install
bun run build
omp install ./

Then restart oh-my-pi.

To update the installed plugin after publishing a new version:

omp update @citywalki/oh-my-pi-honcho-memory

Publishing

Do not run npm publish locally. Releases are automated via GitHub Actions.

To publish a new version:

1. Make sure main is in a releasable state and all changes are pushed.
2. Run the release script locally to bump the version and push a tag:

bun run release patch   # or minor / major

This runs npm version, which bumps package.json, commits, tags vX.Y.Z, and pushes the tag to GitHub.

3. The Release workflow (.github/workflows/release.yml) will build the package and publish it to npm with provenance.

A CI workflow also runs on every push and pull request to verify the build and type checks.
