  • I have read and reviewed the documentation changes to the best of my ability.
  • If the change is significant, I have run the documentation site locally and confirmed it renders as expected.

Summary of changes

Adds a new SDK guide page for Conversation.fork(), a first-class primitive for branching off an existing conversation for follow-up exploration without contaminating the original audit trail.

The guide covers:

  • Basic usage — fork a conversation, source isolation, deep-copy semantics
  • Agent replacement — fork with a different agent for A/B testing or tool-change scenarios
  • Tags and metadata — title and arbitrary tags on forks
  • Metrics reset — controlling whether cost/token stats carry over or start fresh
  • Agent-server REST endpointPOST /api/conversations/{id}/fork
  • Full ready-to-run example — uses a real LLM, demonstrates fork end-to-end

Navigation: Added sdk/guides/convo-fork as the first item in the "Conversation Features" group in docs.json.

Related: This documents the feature implemented in OpenHands/software-agent-sdk#2841 (closes OpenHands/software-agent-sdk#2840).

Note: Branch name matches the SDK PR branch (openhands/conversation-fork) so the check-documented-examples CI can discover the docs.


This PR was created by an AI agent (OpenHands) on behalf of the user.

Add SDK guide page for the new Conversation.fork() primitive that lets
users branch off an existing conversation for follow-up exploration
without contaminating the original audit trail.

Covers:
  - Basic usage (fork, source isolation, deep-copy semantics)
  - Fork with a different agent (A/B testing, tool-change)
  - Tags, metadata, and metrics reset
  - Agent-server REST endpoint (POST /api/conversations/{id}/fork)
  - Full ready-to-run example (no LLM calls needed)

Added to Conversation Features nav group in docs.json.

Update the ready-to-run example to match the real-LLM version from
the SDK repo, and add the RunExampleCode shared snippet.

- Update embedded remote example (02_remote_agent_server/11_conversation_fork.py)
  to match bug-fixed version: relaxed event count assertions for remote
  forks since WebSocket-only events aren't persisted server-side
- Fix 'What Gets Copied' table: removed incorrect entries for
  confirmation_policy and security_analyzer (not copied in fork),
  added accurate entries for agent_state, activated_knowledge_skills,
  and tags

Summary

The /iterate request has been fully addressed. Here's what was done:

Checklist

  • Reviewed CI status — All 4/4 checks were green on the final SHA
  • Reviewed bot feedback — The all-hands-bot gave a 🟢 "Good taste" rating, meaning production-ready
  • Addressed actionable inline comment — Fixed focus={8-11}focus={4-8} on the "Agent replacement" code block to correctly highlight the fork call (lines 4–8 in the code block)
  • Resolved all review threads — Both inline threads (the focus range suggestion and the "nice touch" compliment) were replied to and resolved
  • Re-requested review from bot — Bot re-reviewed on the new SHA (f4f016a) and confirmed 🟢 with zero new comments
  • Verified final state — PR is mergeable, not draft, all checks green, no unresolved threads

Conciseness

The only change made was a single-character edit (8-114-8) in one line of sdk/guides/convo-fork.mdx — directly addressing the reviewer bot's suggestion. No extraneous changes were introduced.

Result

PR #459 is now fully iterated: the reviewer bot approved with no additional comments on the current SHA, and all CI checks pass. It awaits human reviewer (enyst) approval to merge.

Add explicit guidance on GitHub review event values (APPROVE,
REQUEST_CHANGES, COMMENT) to the repo-specific code-review skill.
This mirrors the fix in OpenHands/extensions#185 that teaches the
general github-pr-review skill the same thing.

Previously the bot always submitted COMMENTED reviews even for clean
PRs because no skill told it to use the APPROVE event.

🟢 Good taste - Comprehensive, well-structured documentation following all repository guidelines. Examples are executable with proper assertions, navigation is correct, and auto-sync syntax is properly formatted.

[RISK ASSESSMENT]

  • [Overall PR] ⚠️ Risk Assessment: 🟢 LOW
    Documentation-only change adding a new guide for an implemented SDK feature. No code changes, no breaking changes, follows established patterns.
