Summary

Update the TinyAgents gitlink to the session recovery fix in tinyhumansai/tinyagents#360. When Claude Code explicitly reports that a resumed session does not exist, the driver clears the stale mapping and retries once as a new session with full conversation history. Generic failures do not trigger retries.

The OpenHuman change is the dependency integration; the behavior and regression coverage live in TinyAgents, which owns the driver and session store. The dependency PR must land before this gitlink update can merge.

Closes #5648

Validation

  • cargo fmt --check (in vendor/tinyagents)
  • cargo test -p tinyagents-harness --features claude-code providers::claude_code::driver::tests -- --nocapture (16 passed)
  • cargo test -p tinyagents-harness --features claude-code providers::claude_code::session_store::tests -- --nocapture (4 passed)

The focused tests verify exact error recognition and durable mapping removal. There is no fake CLI process harness in TinyAgents, so retry orchestration is not end-to-end tested.

  • cargo test -p tinyagents-integration-tests --test dependency_boundary (6 passed). The new helper shifted the two known ChatMessage lines in driver.rs (71/237 to 75/241); tinyagents#360 now updates that line baseline, which was the cause of its red CI.

This PR is a draft until tinyhumansai/tinyagents#360 merges; the gitlink should then be moved to the merged commit on tinyagents main.

P2 Badge Update docs for stale-session recovery

When a stored Claude UUID is stale, this pin intentionally handles a non-zero --resume exit by clearing the mapping and retrying, but the checked source and generated provider guides (gitbooks/developing/providers/claude-code.md:59-74 and docs/gitbooks/en/developing/providers/claude-code.md:59-74) still enumerate a single spawn and state that every non-zero exit returns stderr. That makes the troubleshooting contract wrong for the exact recovery path introduced here, so update the source guide and regenerate its mirror.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Handle missing-session errors in terminal result events.

Claude Code 2.1.86 can report a missing session in a result event with subtype: "error_during_execution" and an errors array. The vendored parser stores that event in Result.raw, but the event mapper ignores raw.errors and only sets error for subtype "error". The driver therefore misses recovery: a nonzero exit takes the generic error path, while a zero exit can return without clearing the stale mapping or retrying. Extract and classify terminal result errors, and test this response shape. (raw.githubusercontent.com)

Wait for the upstream recovery PR to land.

As of October 9, 2026, TinyAgents PR #360 is still open, and this gitlink points to its one-commit head. The PR objective requires #360 to land before this reference merges. Merge the dependency PR first, then confirm the gitlink points to the landed commit. (github.com)

Superseded by #7254. tinyagents#360 merged and shipped in tinyagents v2.1.4, and #7254 pins that release, which carries this fix along with the other Claude Code fixes. This PR only moved the same vendor/tinyagents gitlink. #7254 now closes #5648.
