diploid-plugins

Built-in state plugins for diploid-agent.

These plugins implement the diploid-agent plugin contract (StatePlugin lifecycle hooks) and are loaded by the harness through the harness.plugins config.

Included plugins

• body — physical/emotional body state that persists across sessions and transport restarts. Includes a felt layer: felt_warmth (an ember that fades per wake/turn, not per wall-clock minute — a restart is not an experience) and felt_summary (one agent-authored line of texture via the body_felt MCP tool; never synthesized from telemetry). Reads are pure — state_for_prompt never mutates.
• continuity — wake state, time asleep, last stop reason, pending dispatches, and active/interrupted-turn breadcrumbs (current_intent/last_side_effect).
• working_memory — a chat-scoped scratchpad for the current turn.
• persistent_memory — auto-recall and auto-promote of ```memory blocks, including mid-stream promotion while the reply is still being written.
• planner — turn a user request into an executable plan.
• auto_continue — resume a turn automatically after a configured stop reason.
• self_state — a first-person self-state note across sessions, with a first-person guard that keeps the previous note if a new block is not written in I am/We are/My form.
• self_management — in-chat plugin enable/disable and approval tools.
• curriculum — language-learning target, unit, and vocabulary tracking.
• identity — self-narrative / identity prompt block.

Install

pip install diploid-agent[plugins]
# or explicitly
pip install diploid-agent diploid-plugins

Usage

In config/harness.yaml:

harness:
  plugins:
    - name: continuity
      module: diploid_plugins.continuity
      prompt_slot: wake
      first_prompt_only: true
      prompt_order: 0
      state_file: chat_wake_state.json
      max_prompt_chars: 1024
    - name: working_memory
      module: diploid_plugins.working_memory
      prompt_slot: working_memory
      first_prompt_only: false
      prompt_order: 40
      state_file: chat_working_memory.json
      max_prompt_chars: 1024
    # ... add the rest as needed

Development

python -m venv .venv
source .venv/bin/activate
pip install -e ".[dev]"
pytest

Hot reload

With an editable install, plugin changes go live in a running harness without a service restart: POST /plugin/reload (or Telegram /plugin reload <name>) deep-reloads the plugin's whole package subtree — every already-imported submodule, then the package itself — and recycles its instances.

Keep module-level code side-effect free: reload re-executes it. Do real work in start(), release resources in stop(). A module that fails to import makes the reload raise and leaves the running instances untouched. Changes in code outside the plugin's own subtree (e.g. a shared helper package) are not picked up — reload each dependent plugin or restart the service.
