# Review by Linus Torvalds (Round 2)

---

VERDICT: approve

FINDINGS:
- [src/colonyos/cli.py, REPL loop ~line 590]: REPL stores `last_direct_session_id` on success but does not clear it on failure (unlike the TUI path which does `last_direct_session_id = None` on failure). Minor asymmetry — not a blocker because `_run_direct_agent()` handles fallback internally, but the REPL will hold a stale session ID until `/new` or a mode switch.
- [src/colonyos/agent.py, line 97]: The `**({"resume": resume, "continue_conversation": True} if resume else {})` unpacking is correct but slightly clever for what amounts to two keyword arguments. A simple `if resume:` block setting them explicitly would be more readable. Style nit, not a functional issue.
- [src/colonyos/cli.py, _run_direct_agent]: The `import re` at the top of the function shadows the module-level `import re` already present — redundant but harmless.

SYNTHESIS:
This is a clean, minimal implementation that does exactly what the PRD asks for — nothing more, nothing less. The core change is threading one string through the SDK's existing resume mechanism, which is precisely the right approach. The data structures are simple and correct: a nullable string for session state, a tuple return for the enriched `_run_direct_agent`. The test coverage is solid with 16 dedicated tests covering the happy path, fallback, validation, and command handling. The one real finding — asymmetric failure handling between REPL and TUI — is low-risk because the retry logic inside `_run_direct_agent` compensates for it, but it should be cleaned up in a follow-up. Ship it.
