oni-comb-rs: Skill for Claude Code

.agents/skills/takt-optimizer/SKILL.md

takt-optimizer is a skill for Claude Code, Codex from j5ik2o/oni-comb-rs. It costs 266 tokens per session (4,104 once invoked), scanned A, original, Apache-2.0.

A TAKT workflow optimizer that edits workflow configuration and supporting files to reduce prompt cost and simplify execution. TAKT is a tool for running structured AI workflows.

In plain words
What is it for?
Use it to optimize TAKT pieces and facets, apply findings from TAKT analysis, and generate the revised files.
Why use it?
It helps identify ways to use fewer tokens, reuse more rules, simplify control flow, and improve parallel execution while considering quality trade-offs.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents).

This is j5ik2o/oni-comb-rs's own configuration. It tells Claude Code and Codex how to work on oni-comb-rs 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 oni-comb-rs configures →

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is bash .agents/skills/takt-optimize/scripts/validate-takt-files.sh.

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.

ModelPer sessionOnce invoked
Fable 5.1 $0.00266 $0.04104
Opus 5.5 $0.00106 $0.01642
Sonnet 5.5 $0.00053 $0.00821
Haiku 4.5 $0.00027 $0.00410

Measured 2mo ago against content hash 35a98401019c, method: parsed. Prices are Anthropic first-party input rates as of 2026-10-07, from the pricing page.

Security

Grade A, and why

takt-optimizer 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 2mo 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.

最適化カテゴリ

1. トークン消費削減

プロンプト構築時のトークン量を削減する。

エンジンのプロンプト構築順序（参照: engine.md）:

ペルソナ → ポリシー → コンテキスト → ナレッジ → インストラクション
→ タスク → 前回出力 → レポート指示 → タグ指示 → ポリシーリマインダー

注意: ポリシーは冒頭と末尾に2回注入される（Lost in the Middle対策）。ポリシーの肥大化はトークン消費を2倍にする。

最適化 手法 効果
ペルソナ圧縮 冗長な記述の除去、サイズ上限内への圧縮 各ムーブメントで削減
ポリシー分割 巨大ポリシーを用途別に分割し、必要なムーブメントにのみ割り当て 2倍効果（リマインダー分）
ナレッジ絞り込み ムーブメントに不要なナレッジ参照を除去 不要コンテキスト削減
インストラクション簡素化 自動注入される内容の手動記述を除去 重複排除
出力契約スリム化 30行超の出力契約を圧縮 レポート指示部分で削減

ファセットサイズ目安:

ファセット 推奨 上限
Persona (simple) 30-50行 100行
Persona (expert) 50-300行 550行
Policy 60-250行 300行
Instruction (review) 5-12行 -
Instruction (plan/fix) 10-20行 -
Instruction (implement) 30-50行 -
Output Contract 10-25行 30行

2. ムーブメント統合

不要なムーブメントを統合してワークフロー全体のステップ数を減らす。

連続する同一ペルソナ 隣接ムーブメントが同じペルソナ 1ムーブメントに統合
単一ルール遷移 ルールが1つで無条件遷移 前後ムーブメントと統合検討

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.
