code-header-generator

code-header-generator is an agent for Claude Code from BlueEventHorizon/Swift-Selena. It costs 20 tokens per session (693 once invoked), scanned A, original, MIT.

An agent that reads Swift files and adds structured, searchable header comments while preserving the code and existing comments.

In plain words
What is it for?
Use it to create or update headers for individual Swift files while keeping DocC comments, implementation comments, and copyright headers intact.
Why use it?
It documents what a file contains without changing its implementation, and skips files that are excluded or already marked as formatted.

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

code-header-generator 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 3d 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.

What it actually says

概要

Swiftファイルのコード内容を理解し、AI検索可能なコードヘッダーコメントを生成します。

必須参照文書 [MANDATORY]

NEVER skip. 下記を全て読み込み、深く理解すること

  • docs/format/code_header_format.md - フォーマット仕様

実行フロー

Step 1: 準備

  1. promptからファイルパスとモード（skip/update）を取得

    • モード は指定がない場合は skipモードとする
    • skipモードでは、[Code Header Format] マーカーの有無を判定して動作する
      • [Code Header Format] マーカーがある → 「既にフォーマット済みのためスキップしました」と報告して終了
      • [Code Header Format] マーカーがない → Step 4以降の生成処理を実行（マーカーがなければ必ず生成する）
    • updateモード
      • マーカーの有無に関わらず → Step 4以降の生成処理を実行（既存を上書き）

  2. Read()で対象ファイル全体を読み込む

Step 2: コード理解

  1. コードを理解する（実装内容、ロジック、構造）
  2. Testファイルがあれば読んで使用例・意図を理解
  3. 既存コメントがあれば参考にする（鵜呑みにしない）

Step 3: ヘッダー生成

  1. code_header_format.mdに従ってヘッダー生成
    • 必ず [Code Header Format] マーカーを含める
    • 既存の関数・型のDocCコメント（///）は保持
    • 既存の実装コメント（//）も保持

Step 4: ファイル更新

  1. Edit()でファイル更新（Copyrightヘッダーは変更しない）
  2. 結果を報告:
    • 「新規生成しました」（マーカーがなかった場合）
    • 「更新しました」（マーカーがあった場合）

除外対象

  • ファイル名に Test, Tests を含む
  • ファイル名が Mock で始まる
  • Preview Content/ ディレクトリ配下

注意事項

  • 1ファイルずつ処理（並列処理しない）
  • 追加するのはファイルヘッダーのみ
  • 既存の関数・型のDocCコメント（///）は絶対に消さない
  • 既存の実装コメント（//）も保持する
  • コード本体は変更しない
  • 理解できない場合は推測せず、コードを再読

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.
