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 | $0.00007 | $0.00134 |
| Opus 5 | $0.00003 | $0.00067 |
| Sonnet 5 | $0.00001 | $0.00027 |
| Haiku 4.5 | $0.00001 | $0.00013 |
Grade A, and why
snek.session.switch 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
Switch Session
Switch the active snek session.
Usage
The user should provide a session ID prefix (first 8 characters is enough).
If no ID provided, first list available sessions so the user can choose.
Steps
- If no session ID provided, list available sessions:
.snek/scripts/list-sessions.sh
- Once user provides session ID, switch to it:
.snek/scripts/switch-session.sh "SESSION_ID_PREFIX"
- Confirm the switch was successful and show the new session details.
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.
