name	orch-add-feature
description	Orchestrate building a brand-new feature end to end — research, plan, TDD implementation, review, and gated commit — by delegating each phase to the matching ECC agent. Use when adding a capability that does not exist yet.

orch-add-feature

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

When to Use

• The user wants a capability that does not exist yet ("add", "build", "implement", "support …").
• It is net-new behavior — not a correction (orch-fix-defect) and not an alteration of existing behavior (orch-change-feature).

Operation settings

• Default size floor: standard — run Research + Plan unless clearly small.
• Phase mask: 0 → 1 → 2 → 4 → 5 → 6 (skip 3 Scaffold; that is MVP-only).
• First move (phase 4): write new failing tests for the new behavior, then implement to green.

How It Works

1. Run the orch-pipeline engine with the settings above.
2. Classify size first; small / trivial features collapse toward 4 → 5 → 6.
3. Stop at Gate 1 (plan approval) and Gate 2 (pre-commit).
4. Add security-reviewer if the feature touches a security trigger.

Related: /feature-dev is a standalone version of this flow. orch-add-feature differs by sharing the orch-pipeline engine — the size classifier and the two gates — with the rest of the family, so it right-sizes trivial features to 4 → 5 → 6.

Example

orch-add-feature: add OAuth2 login to nws-poller
→ research existing auth libs → plan task_list  [GATE 1: approve]
→ TDD each task → code-review (+ security-reviewer: auth path)
→ commit  [GATE 2: confirm]
