ci: harden the agent loop — turn-cap headroom + failure surfacing#56
Merged
Conversation
Two robustness fixes prompted by the S0 scaffold run hitting error_max_turns (it built everything but ran out of turns before committing, pushing nothing): - Raise --max-turns 30 -> 50 as a safety margin for a well-sized slice. Small slices remain the design (see CLAUDE.md); the cap still stops a runaway task. - Add a `failure()` step that, in the hands-off model, comments the run link on the issue and labels it needs-triage instead of failing silently in the Actions tab. Posted with GITHUB_TOKEN (a notification, never a re-trigger — the bot actor is excluded and GITHUB_TOKEN runs are suppressed, so it cannot re-invoke the agent).

Rolls the S0 turn-cap fix into the system — the workflow half (the convention half is #55).
Prompted by the first S0 scaffold run failing on
error_max_turns: the agent built the whole scaffold but ran out of its 30-turn budget before committing, so nothing was pushed and the failure was only caught by a manual watcher.Changes to
