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 5.1 | $0.00212 | $0.00212 |
| Opus 5 | $0.00106 | $0.00106 |
| Sonnet 5 | $0.00042 | $0.00042 |
| Haiku 4.5 | $0.00021 | $0.00021 |
Grade A, and why
leave-the-corpse 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
Leave the Corpse
When the user says "show me the corpse" or "leave the corpse", this means:
- DO: Leave the failing code in place exactly as written
- DO: Let verification errors remain visible in the output
- DO NOT: Comment out the module in
lib.rs - DO NOT: Comment out the failing assertions or functions
- DO NOT: Add
#[verifier::external_body]to skip verification - DO NOT: Add
assume(...)oradmit()to force it through - DO NOT: Revert or delete the failing code
The point is to preserve the failure as evidence. The user wants to see exactly what fails and why.
This is related to the failed-experiments rule — failed code is valuable documentation.
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.
