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 | $0.00038 | $0.00378 |
| Opus 5.5 | $0.00015 | $0.00151 |
| Sonnet 5.5 | $0.00008 | $0.00076 |
| Haiku 4.5 | $0.00004 | $0.00038 |
Grade A, and why
claude-session 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 5d 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
Claude Session Manager
Claude Code CLI のセッションIDを ~/.cache/ai-agent-sessions/claude-session-<name> に保存し、複数セッションを混同せずに継続できるようにする。
使い方
セッション作成（ID保存）
~/.claude/skills/claude-session/scripts/start.sh <name> "<初期プロンプト>"
例:
~/.claude/skills/claude-session/scripts/start.sh analyst "調査役として動いてください"
セッション継続（保存済みIDでresume）
~/.claude/skills/claude-session/scripts/send.sh <name> "<追加プロンプト>"
例:
~/.claude/skills/claude-session/scripts/send.sh analyst "この結果を要約して"

注意事項
- セッションIDは
~/.cache/ai-agent-sessionsに保存される - 実装は共通コアに統一され、ログ探索結果をメタ情報として再利用する
What ships with it
4 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.
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.

claude-session is a skill published in the GitHub repository akaghef/M3E (11 stars, last pushed 5d ago), licensed MIT. It adds 38 tokens to every session and 378 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-10-02.
