| description | Orchestrate altering an existing, working feature to new desired behavior — update its tests to the new spec, change the implementation to match, review, and gated commit. Use when behavior is not broken but should be different. |

orch-change-feature
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
- Run the
orch-pipeline engine with the settings above.
- Keep the plan light — only
standard+ size warrants the full planner pass.
- Stop at Gate 1 (plan / changed-test approval) and Gate 2 (pre-commit).
- 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]
