claude-code-orchestra: Skill for Claude Code

.claude/skills/feature/SKILL.md

feature is a skill for Claude Code, Codex from DeL-TaiseiOzaki/claude-code-orchestra. It costs 147 tokens per session (9,051 once invoked), scanned A, original, MIT.

A workflow for planning and building software features in either an existing codebase or a new project. It covers understanding the work, research and design where needed, approval, implementation, and review.

In plain words
What is it for?
Use it to scope a feature, design its implementation, create a plan, obtain approval, and route simple or complex work to the appropriate coding and review process.
Why use it?
It gives feature work a defined path from unclear request to reviewed code, while adjusting the process to the size and complexity of the change.

Skill for Claude CodeCodex

Written for Claude Code and Codex: installed under .claude/, but also runs codex exec. Also seen: reads .claude/ paths; mentions CLAUDE.md; mentions subagents.

This is DeL-TaiseiOzaki/claude-code-orchestra's own configuration. It tells Claude Code and Codex how to work on claude-code-orchestra itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything claude-code-orchestra configures →

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is python3 .claude/skills/_shared/workspace.py \.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

feature scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 892 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Feature

One entry point for feature work, two modes:

  • MODE=existing (old /add-feature path): the feature goes into an established codebase whose conventions are already known. No external research needed → Codex-direct scope → design → plan.
  • MODE=greenfield (old /start-feature path): a large or new feature that needs external research and parallel design → Agent Teams (Researcher + Architect) with bidirectional communication.

Both modes converge on a shared Phase 3: user approval + complexity-routed implementation.

Preflight: ensure codex CLI is current (see codex-system skill).

/feature <feature description>
    | MODE determination (AskUserQuestion when ambiguous)
    ├─ MODE=existing   : Phase 1E SCOPE  -> Phase 2E DESIGN (Codex direct)
    └─ MODE=greenfield : Phase 1G UNDERSTAND -> Phase 2G RESEARCH & DESIGN (Agent Teams)
    | Phase 3 (shared): PLAN, APPROVE & IMPLEMENT
    SIMPLE   (1-3 files, <50 LOC) -> Codex danger-full-access direct
    MODERATE (3-5 files)          -> Codex danger-full-access + /team-execute --review-only
    COMPLEX  (5+ files)           -> /team-execute (implement + review)

Mode Determination (always first)

Decide the MODE before anything else. Signals:

Signal MODE=existing MODE=greenfield
Codebase state Established, conventions known New area, or conventions absent
External research needed No — Codex reasons about existing patterns directly Yes — libraries/tools/reference architectures must be researched
Feature size Localized addition Large, multi-module, or project kickoff
Design source Codex (read-only consults) Agent Teams (Researcher + Architect)

If the signals are mixed or unclear, ask via AskUserQuestion — do NOT guess:

question: "Which feature mode applies?"
multiSelect: false
options:
  - label: "existing"
    description: "Add to an established codebase; conventions known; no external research (old /add-feature)."
  - label: "greenfield"
    description: "Large/new feature; needs external research and parallel design via Agent Teams (old /start-feature)."

What ships with it

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
