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 | $0.00014 | $0.00461 |
| Opus 5 | $0.00007 | $0.00230 |
| Sonnet 5 | $0.00003 | $0.00092 |
| Haiku 4.5 | $0.00001 | $0.00046 |
Grade A, and why
spool scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Search your thinking with spool — a local search engine over your Claude Code and Codex CLI sessions.
Steps
- Check if spool is installed
which spool
If the command is not found, tell the user:
spoolCLI is not installed. Run:npm install -g @spool/clithenspool syncto index your sessions. Stop here.
- Run the search
spool search "$ARGS" --json --limit 5
where $ARGS is everything the user passed to /spool.
- Present the results
For each result in the JSON array, show:
- Session title and date (
startedAt) - Source (claude or codex) and project path
- The snippet with highlighted terms (strip
<mark>/</mark>tags for plain display) - A note of the session UUID
Example format:
1. [claude] /code/myproject — 2026-03-20
"…evaluated the database sharding tradeoffs and reached a decision…"
UUID: abc123
2. [codex] /code/api — 2026-03-18
"…the race condition was caused by a shared map write without a mutex…"
UUID: def456
- Offer to load a full session
Ask: "Want to see the full conversation for any of these? I can load it with spool show <uuid>."
If the user says yes (or specifies a number/UUID), run:
spool show <uuid>
Include the output as context in your next reply.
Tips
- Add
--source claudeor--source codexto filter by source - Add
--since 7dto limit to the last 7 days - Use quotes for exact phrases:
/spool "read replicas" - Run
spool syncfirst if results seem stale
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.

spool is a skill published in the GitHub repository anneheartrecord/charles-skill (3 stars, last pushed 27d ago), licensed MIT. It adds 14 tokens to every session and 461 once invoked, about $0.0001 per session on Opus 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 2026-08-31.
