# Agent Skill to Orch Change Feature

**Summary:** Agent Skill to Orch Change Feature is a verified SKILL blueprint on Promptally in Fullstack & Backend Engineering optimized for leading AI models. 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. Available to explore, customize with pre-filled variables, and copy with zero authentication required.

# orch-change-feature

Actor · action · target: **orch · change · feature**. Thin wrapper over the
shared engine in [`orch-pipeline`](../orch-pipeline/SKILL.md).

## 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]
```
