orch-change-feature

What does orch-change-feature do?

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

When to Use

• An existing feature works, but the desired behavior is different ("change", "adjust", "make it also …", "instead of X do Y").
• Distinguish from siblings:
  • not broken → not orch-fix-defect (no bug to reproduce).
  • not new → not orch-add-feature (the capability already exists).

Operation settings

• Default size floor: small — most tweaks are a function or two.
• Phase mask: 0 → (1 only if the new behavior needs research) → light 2 → 4 → 5 → 6.
• First move (phase 4): update the existing tests to express the new desired behavior, then change the implementation until they pass. Changing the tests first is what separates a tweak from a fix.

How It Works

1. Run the orch-pipeline engine with the settings above.
2. Keep the plan light — only standard+ size warrants the full planner pass.
3. Stop at Gate 1 (plan / changed-test approval) and Gate 2 (pre-commit).
4. Add security-reviewer if the change touches a security trigger.

Example

orch-change-feature: make nws-poller alert at 2 warnings instead of 3
→ update threshold tests to new spec → change impl to green
→ code-review → commit  [GATE 2: confirm]
