Honcho TypeScript SDK Migration (v1.6.0 → v2.0.0)

Overview

This skill migrates code from @honcho-ai/sdk v1.6.0 to v2.0.0 (required for Honcho 3.0.0+).

Key breaking changes:

• @honcho-ai/core dependency removed
• "Observation" → "Conclusion" terminology
• "Deriver" → "Queue" terminology
• getConfig/setConfig → getConfiguration/setConfiguration
• snake_case → camelCase throughout
• Streaming via chatStream() instead of chat({ stream: true })
• Representation class removed (returns string now)

Quick Migration

1. Update dependencies

Remove @honcho-ai/core from package.json. The SDK now has its own HTTP client.

2. Replace .core with .http

// Before
const workspace = await client.core.workspaces.getOrCreate({ id: 'my-workspace' })

// After
const response = await client.http.post('/v3/workspaces', { body: { id: 'my-workspace' } })

3. Rename configuration methods

// Before
await honcho.getConfig()
await honcho.setConfig({ key: 'value' })
await peer.getConfig()
await session.getConfig()

// After
await honcho.getConfiguration()
await honcho.setConfiguration({ reasoning: { enabled: true } })
await peer.getConfiguration()
await session.getConfiguration()

4. Rename listing methods

// Before
const peers = await honcho.getPeers()
const sessions = await honcho.getSessions()
const workspaces = await honcho.getWorkspaces()  // string[]

// After
const peers = await honcho.peers()
const sessions = await honcho.sessions()
const workspaces = await honcho.workspaces()  // Page<string>

5. Update streaming

// Before
const stream = await peer.chat('Hello', { stream: true })

// After
const stream = await peer.chatStream('Hello')

6. Update observations → conclusions

// Before
peer.observations
peer.observationsOf('bob')
maxObservations: 50
includeMostDerived: true

// After
peer.conclusions
peer.conclusionsOf('bob')
maxConclusions: 50
includeMostFrequent: true

7. Update queue status methods

// Before
await honcho.getDeriverStatus({ observer: peer })
await honcho.pollDeriverStatus({ timeoutMs: 60000 })  // REMOVE - see note below

// After
await honcho.queueStatus({ observer: peer })
// pollDeriverStatus() has no replacement - see note below

Important: pollDeriverStatus() and its polling pattern have been removed entirely. Do not rely on the queue ever being empty. The queue is a continuous processing system—new messages may arrive at any time, and waiting for "completion" is not a valid pattern. If your code previously polled for queue completion, redesign it to work without that assumption.

8. Convert snake_case to camelCase

// Before
message.peer_id
message.session_id
message.created_at
message.token_count
{ observe_me: true, observe_others: false }
{ created_at: '2024-01-01' }

// After
message.peerId
message.sessionId
message.createdAt
message.tokenCount
{ observeMe: true, observeOthers: false }
{ createdAt: '2024-01-01' }

9. Update representation calls

// Before
const rep = await peer.workingRep(session, target, options)
console.log(rep.explicit)  // ExplicitObservation[]
console.log(rep.deductive) // DeductiveObservation[]

// After
const rep = await peer.representation({ session, target, ...options })
console.log(rep)  // string

10. Move updateMessage to session

// Before
await honcho.updateMessage(message, metadata, session)

// After
await session.updateMessage(message, metadata)
