workspace-count-tokens

workspace-count-tokens is a skill for Claude Code, Codex from eaglesakura/agent-skills. It costs 106 tokens per session (950 once invoked), scanned A, original, MIT.

A workspace measurement skill that estimates how many tokens are used by project instructions, rules, skills, and related documentation.

In plain words
What is it for?
Use it to measure default instructions and dynamically loaded skills or documents, with results recorded in the required report format.
Why use it?
It helps identify how much context these materials occupy when comparing or managing workspace context size.

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.

Fable 5.1 $0.00106 $0.00950
Opus 5.5 $0.00042 $0.00380
Sonnet 5.5 $0.00021 $0.00190

Security

Grade A, and why

workspace-count-tokens 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.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/count_workspace_tokens.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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

Workspace / Count Tokens

ファイルベースでトークン量を概算する。課金トークンや Cursor UI 表示との一致は保証しない。 出力は必ず assets/report.md の見出し・表カラムに従う。

いつ使うか

  • デフォルト Context や SKILL / docs のトークン概算を測る・比較するとき
  • 「コンテキストサイズ」「SKILL が何トークンか」を知りたいとき

いつ使わないか

  • 会話全体・ツール結果込みの実リクエスト課金を監査するとき
  • 単一ファイルの厳密カウントだけで足りるとき

計測対象

区分 デフォルト（常時） 動的（最大）
AGENTS.md / alwaysApply rules / .cursorrules 本文 -
非 always の rule description のみ -
SKILL.md description のみ 全文（他 SKILL 経由の追加ロードは含めない）
docs/ doc/ references/ 含めない 全文
User Skills（--include-user-skills） description 全文

含めない: システムプロンプト、ツール/MCP スキーマ、User Rules（Settings）、オープン中ファイル、会話履歴。

手順

  1. scripts/count_workspace_tokens.py を 実行する（自前集計よりスクリプト優先）
  2. 標準出力のレポートを assets/report.md 構成のままユーザーへ示す（3セクションを混ぜない）
    • 各セクション先頭の統計（ファイル数合計 / トークン量合計）を残す
    • トークン量合計 は常にキロトークン（例: 0.7K Tokens、5.0K Tokens、小数点以下第1位）
  3. 概算である旨と未計測項目を一言添える
  4. tiktoken が無ければスクリプトの提案どおりインストールを案内する
  5. 結果を残すなら .ai-agent/tmp/ へ（workspace-agent-temporary）
# 推奨依存
python3 -m pip install tiktoken
# または: python3 -m venv /tmp/tokencount && /tmp/tokencount/bin/pip install tiktoken

# SKILL_DIR は本 SKILL.md があるディレクトリ
SCRIPT="$SKILL_DIR/scripts/count_workspace_tokens.py"
python3 "$SCRIPT" --root .
# multi-root は --root を繰り返し。ユーザー SKILL 込みは --include-user-skills。JSON は --json。

パス解決は workspace-resolve-file-path に従う。トークナイザは tiktoken の o200k_base、無ければ chars/4。

DO / DO NOT

  • DO: デフォルトと動的（SKILL / ドキュメント）を分けて報告する
  • DO NOT: UI のコンテキスト％や課金トークンと同一視する
  • DO NOT: eval / iteration / skill-snapshot 配下を本番 SKILL として数える
Files

What ships with it

2 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.
