# Orch Add Feature

> 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.

## Install

```sh
agentstack add skill-affaan-m-ecc-orch-add-feature
```

Requires the [AgentStack CLI](https://agentstack.voostack.com/docs/cli). Works with Claude Code, Cursor, and any MCP-compatible agent.

## About

# orch-add-feature

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

## 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]
```
