migrate-py skillB
migrate-py is agent-read markdown (skill) from plastic-labs/claude-honcho: Migrates Honcho Python SDK code from v1.6.0 to v2.0.0. Use when upgrading honcho package, fixing breaking changes after upgrade, or when errors mention AsyncHoncho, observations, Representation class, .core property, or get_config methods..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# Honcho Python SDK Migration (v1.6.0 → v2.0.0)
## Overview
This skill migrates code from `honcho` Python SDK v1.6.0 to v2.0.0 (required for Honcho 3.0.0+).
**Key breaking changes:**
- `AsyncHoncho`/`AsyncPeer`/`AsyncSession` removed → use `.aio` accessor
- "Observation" → "Conclusion" terminology
- `Representation` class removed (returns `str` now)
- `get_config`/`set_config` → `get_configuration`/`set_configuration`
- Streaming via `chat_stream()` instead of `chat(stream=True)`
- `poll_deriver_status()` removed
- `.core` property removed
## Quick Migration
### 1. Update async architecture
```python
# Before
from honcho import AsyncHoncho, AsyncPeer, AsyncSession
async_client = AsyncHoncho()
peer = await async_client.peer("user-123")
response = await peer.chat("query")
# After
from honcho import Honcho
client = Honcho()
peer = await client.aio.peer("user-123")
response = await peer.aio.chat("query")
# Async iteration
async for p in client.aio.peers():
print(p.id)
```
### 2. Replace observations with conclusions
```python
# Before
from honcho import Observation, ObservationScope, AsyncObservationScope
scope = peer.observations

How to install
mdr add plastic-labs/claude-honcho/migrate-py@git:20260220.80202bfmdr add plastic-labs/claude-honcho/migrate-py@sha256:4fe8c15395267cfePin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
