What it does

Orch Add Feature is an agent skill from affaan-m/ECC. 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.

Its SKILL.md is about 440 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Testing & QA, covering Test-driven development. The repository describes itself as: The agent harness performance optimization system. Skills, instincts, memory, security, and research-first development for Claude Code, Codex, Opencode, Cursor and beyond. The licence is MIT.

When your agent uses it

  • Adding a capability that does not exist yet
  • Tasks that involve Test-driven development

Example prompts

  • “/orch-add-feature”

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  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.

What it can do on your machine

Read from SKILL.md and the folder at commit 2d515e4. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Orch Add Feature loads about 440 tokens when it runs. Until then it costs about 60 tokens; SKILL.md has 174 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~60
When it runs · the whole SKILL.md, loaded when a task matches
~440

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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]
