breezing

breezing is a skill for Claude Code, Codex from Chachamaru127/claude-code-harness. It costs 43 tokens per session (7,224 once invoked), scanned A, original, MIT.

A team execution mode for running coding work through a plan, implementation, review, and report workflow. It can select different worker backends, including Cursor when explicitly enabled.

In plain words
What is it for?
Use it to plan tasks, delegate implementation, review the combined code changes, and produce a completion report.
Why use it?
It organizes multi-step agent work and adds a review checkpoint before the work is marked complete.

About the project

Claude Code Harness is a development workflow for coding agents that organizes work into planning, implementation, review, synchronization, and release stages. It helps developers keep specifications, tests, independent reviews, and release evidence connected while using tools such as Claude Code, Codex CLI, Cursor, or Grok.

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

breezing 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 5d 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.

Breezing — Team Execution Mode (Codex Host)

この SKILL.md は Codex host 版です。 Claude Code 版は skills/breezing/SKILL.md を参照してください。 backend は resolver で選びます。配布 plugin のフラグなし既定は claude 互換のままです。 --cursor / --backend cursor、または HARNESS_IMPL_BACKEND=cursor を設定した環境では Cursor worker backend を使います。 frontmatter の allowed-tools も、この4つの Codex native tool 名に合わせます。

後方互換エイリアス: harness-work --breezing をチーム実行モードで動かします。

Default Pipeline(plan → work → review → report を 1 コマンドで完走)

Claude Code 版と同一の契約(operator 裁定 2026-07-24。正本: skills/breezing/SKILL.md の同名節):

  1. Plan gate: 依頼スコープの task が Plans.md に無い/不足なら、先に harness-plan を実行してから続行(スコープ既定は「今進められる全作業」)
  2. Work: 既存のチーム実行フロー(per-task review 含む)
  3. Integrated Review Gate(既定 ON): 実装完了後・最終化(完了報告・run 完了宣言)の前に、run 全体 diff に harness-review を実行。review target は通常 {base_ref}..HEAD--no-commit run は working tree(未 commit 変更 + untracked)。fresh-context 独立 reviewer + cross-CLI second opinion を併走させ、APPROVE まで修正 → 再レビューを反復(最大 3 回。未収束は影響 task を cc:WIP に戻して human escalation)
  4. Finalize + Report: gate APPROVE 後に Plans.md 更新・完了報告を確定。最終報告は easy 作法(host に easy skill があればその作法、なければ Completion Report テンプレート)

低リスクの高速 run で 3 を省きたい時は --no-review-gate(per-task review は維持、統合レビューのみスキップ)。

Work Mode Lifecycle (bin/harness work-mode)

Claude Code 版と同一の契約(正本: skills/breezing/SKILL.md の同名節)。 Lead は run 開始時(Plan gate に入る前)に bin/harness work-mode on を実行し、 run 終了時は成功・失敗・中断の全経路bin/harness work-mode off を実行する。 session ID が解決できない場合、work-mode は非ゼロ終了し理由を stderr に出す。

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.
