Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00000 | $0.00554 |
| Opus 5 | $0.00000 | $0.00277 |
| Sonnet 5 | $0.00000 | $0.00111 |
| Haiku 4.5 | $0.00000 | $0.00055 |
Grade A, and why
session-end 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 yesterday.
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.
This is a copy
100% identical to session-end — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 119 lines — stays where its author put it; the contents beside it link to each section on GitHub.
hook session-end
Cleanup and persist session state before ending work.
Usage
npx claude-flow hook session-end [options]
Options
--session-id, -s <id>- Session identifier to end--save-state- Save current session state (default: true)--export-metrics- Export session metrics--generate-summary- Create session summary--cleanup-temp- Remove temporary files
Examples
Basic session end
npx claude-flow hook session-end --session-id "dev-session-2024"
With full export
npx claude-flow hook session-end -s "feature-auth" --export-metrics --generate-summary
Quick close
npx claude-flow hook session-end -s "quick-fix" --save-state false --cleanup-temp
Complete persistence
npx claude-flow hook session-end -s "major-refactor" --save-state --export-metrics --generate-summary

- Closing work session
- Before shutdown
- Switching contexts
Manual usage in agents:
# At session end
npx claude-flow hook session-end --session-id "your-session" --generate-summary

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.
