What is takt-facet-builder?

A workflow for creating and editing TAKT facets, which are separate files for an agent’s persona, policies, instructions, knowledge, or output format. It uses Japanese style guides and templates to keep those files consistent.

Use it to create or edit a persona, policy, instruction, knowledge file, or output contract for a TAKT agent.

It helps turn broad agent behavior into organized, reusable parts with the correct format and type.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00170	$0.03072
Opus 5	$0.00085	$0.01536
Sonnet 5	$0.00034	$0.00614
Haiku 4.5	$0.00017	$0.00307

Measured 10d ago against content hash 7e66c5a8544c, method: parsed. Prices are Anthropic first-party input rates as of 2026-09-11, from the pricing page.

Security

Grade A, and why

takt-facet-builder 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 10d 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.

ワークフロー

Step 1: ファセット種別の判定

ユーザーの要件から、作成すべきファセット種別を判定する。

この内容は…
├── 特定エージェントのidentity・専門知識 → Persona
├── 複数エージェントが共有する行動規範 → Policy
├── ムーブメント固有の実行手順 → Instruction
├── 判断の前提となる参照情報 → Knowledge
└── エージェント出力の構造定義 → Output Contract

ファセット	配置先	対象	キー判断
Persona	system prompt	1エージェント	「この知識はこのエージェント固有か？」
Policy	user message内	複数エージェント	「複数エージェントが同じルールに従うか？」
Instruction	Phase 1 message	1ムーブメント	「この手順はこのムーブメント固有か？」
Knowledge	user message内	1+エージェント	「判断の前提となる参照情報か？」
Output Contract	Phase 2 message	1レポート	「後続が`{report:filename}`で参照するか？」

Step 2: ビルトイン確認

同種のビルトインファセットを確認し、再利用できるか判断する。

ファセット	ビルトイン例
Persona	coder, planner, architecture-reviewer, qa-reviewer, supervisor, security-reviewer, frontend-reviewer, cqrs-es-reviewer, requirements-reviewer, testing-reviewer, terraform-reviewer, dual-supervisor
Policy	coding, review, testing, qa, ai-antipattern
Instruction	plan, implement, implement-after-tests, write-tests-first, team-leader-implement, dual-team-leader-implement, review-arch, review-qa, review-security, review-frontend, review-cqrs-es, review-requirements, review-test, review-terraform, supervise, fix, ai-review, ai-fix, loop-monitor-ai-fix, loop-monitor-reviewers-fix
Knowledge	architecture, backend, cqrs-es, frontend, security, task-decomposition, takt, terraform-aws
Output Contract	plan, architecture-review, ai-review, qa-review, security-review, frontend-review, cqrs-es-review, requirements-review, testing-review, terraform-review, summary, validation

What ships with it

60 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
