Overview / Motivation

Auto-filed by /daily 2026-07-19 (route 2) from a transcript-mined problem (session efbcc710 / #1482 @ 11:48-11:51 UTC).

Goal

Prescribe committed-script (never inline python -c quoting) workload commands for ad-hoc probe dispatches in the /issue backend-dispatch section.

Workflow gap

  • Bug observed: a G1-probe dispatch fired with a placeholder-broken inline staging one-liner that would SyntaxError after phase b0 and trigger a spurious RunPod failover; the just-created GCE instance was cancelled ~2 min after create (reason=orchestrator-quoting-error), burning a create + cancel round.
  • Why it is a workflow gap: inline -c one-liners in --workload-cmd are un-lintable and quoting-fragile; the session's own recovery (rewrite as committed branch scripts, re-dispatch) is the recipe worth prescribing.
  • Confidence (emitter): low (one incident, self-corrected; filed per the standing any-confidence directive)
  • verified-at-filing: grep -n "workload-cmd" .claude/skills/issue/SKILL.md | head → backend-dispatch section present; no existing "committed-script only / no inline -c" prescription found near the dispatch recipe (absence claim — grep python -c guidance in the dispatch section returns no prescriptive rule) (2026-07-19).

Proposed change (candidate diff sketch — refine in planning)

(none — add one paragraph to the backend-dispatch section: ad-hoc probe workloads are committed branch scripts invoked by path; inline -c one-liners in workload commands are the named anti-pattern, incident #1482 2026-07-19)
