Best fit
- An existing feature works, but the desired behavior is different ("change",
- Distinguish from siblings:
- not broken → not orch-fix-defect (no bug to reproduce).

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.

Key source sections
Sections are extracted automatically from the pinned SKILL.md and link back to the source.

Default size floor: small — most tweaks are a function or two.
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.
Review the “Example” section in the pinned source before continuing.
SkillSignal prompt templates
These prompts were written by SkillSignal from the source structure; they are not upstream text.
Task-start prompt
Confirm source fit, inputs, and outputs before acting.
Use orch-change-feature to help me with: [specific task]. Context: [files, data, or background]. Constraints: [environment, scope, and prohibited actions]. Before acting, check the pinned SKILL.md and explain which sections apply, what inputs are still missing, and what you will deliver.
Source-guided execution
Make the Agent explicitly follow the key extracted sections.
Apply the pinned orch-change-feature source to [task]. Pay particular attention to these source sections: “When to Use”, “Operation settings”, “How It Works”, “Example”. Preserve the important decision at each step. Mark facts not covered by the source as “needs confirmation” instead of inventing them. Then verify the result against my acceptance criteria: [criteria].
Result-review prompt
Check omissions, permissions, and source drift before delivery.
Review the current orch-change-feature result: (1) does it satisfy the original task; (2) were any applicable steps or limits in the pinned SKILL.md missed; (3) did it perform any unauthorized file, command, network, or data action; and (4) which conclusions remain unverified? List issues first, then fix only what the source or user authorization supports.
Output checklist
The task matches the purpose documented in the SKILL.md.
The source section “When to Use” has been checked.
The source section “Operation settings” has been checked.
The source section “How It Works” has been checked.
The source section “Example” has been checked.
Inputs, constraints, and acceptance criteria are explicit.
Unverified facts, compatibility, and outcome claims are clearly marked.
Any file, command, network, or data action has been reviewed.
