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 | $0.00000 | $0.00327 |
| Opus 5.5 | $0.00000 | $0.00131 |
| Sonnet 5.5 | $0.00000 | $0.00065 |
| Haiku 4.5 | $0.00000 | $0.00033 |
Grade A, and why
dce-by-tsr scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Dead Code Elimination with tsr
このコマンドはtsrを使用して、TypeScript プロジェクトの未使用コードを検出します。
実行方法
npx tsr 'src/mcp/(lsmcp|typescript-mcp|generic-lsp-mcp)\.ts$'
オプション
--write: 検出された未使用コードを自動的に削除します（注意：テストファイルも削除される可能性があります）--recursive: プロジェクトがクリーンになるまで再帰的にチェックします--project <file>: カスタム tsconfig.json のパスを指定します--include-d-ts: .d.ts ファイルの未使用コードもチェックします
注意事項
- tsr はエントリーポイントから到達可能なコードのみを保持します
- テストファイルは通常のエントリーポイントから参照されないため、未使用として検出される可能性があります
--writeオプションを使用する前に、必ず結果を確認してください
このプロジェクトでの使用例

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.

dce-by-tsr is a command published in the GitHub repository mizchi/lsmcp (454 stars, last pushed 12mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 327 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
