name: orch-fix-defect description: Orchestrate fixing a bug — reproduce it as a failing regression test, fix to green, review, and gated commit — by delegating each phase to the matching ECC agent. Use when existing behavior is broken or wrong. metadata: origin: ECC

orch-fix-defect

Actor · action · target: orch · fix · defect. Thin wrapper over the shared engine in orch-pipeline.

When to Use

• Something is broken: wrong output, an error, a crash, a regression.
• Distinguish from siblings:
  • behavior is correct but you want it different → orch-change-feature.
  • the capability does not exist yet → orch-add-feature.

Operation settings

• Default size floor: small (often trivial).
• Phase mask: 0 → (light 2 only if root cause is non-obvious or standard+) → 4 → 5 → 6. Research (1) is usually skipped.
• First move (phase 4): reproduce the bug as a new failing test (regression test), then fix until it goes green. Proving the bug exists first is what separates a fix from a tweak.

How It Works

1. Run the orch-pipeline engine with the settings above.
2. If the root cause is unclear, scope it with code-explorer before the red test; escalate build breaks to build-error-resolver / /build-fix.
3. Stop at Gate 1 (only if a plan was produced) and Gate 2 (pre-commit).
4. Add security-reviewer if the defect sits in a security-sensitive path.

Example

orch-fix-defect: poller crashes on empty NWS response
→ write failing test reproducing the crash → fix to green
→ code-review → commit  [GATE 2: confirm]   (commit: fix:)
