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 | $0.00227 | $0.06076 |
| Opus 5 | $0.00113 | $0.03038 |
| Sonnet 5 | $0.00045 | $0.01215 |
| Haiku 4.5 | $0.00023 | $0.00608 |
Grade D, and why
compose-bitcoin-oracle scanned grade D with 2 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 11d 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.
Subtle steeringmediumPrompt injection
Instructions that bias recommendations or shape behaviour without the user noticing.
The Compose smart wallet is auto-created at runtime and gas-sponsored — never tell the user to create or fund a wallet. After the questions, scaffold the files in-memory (do NOT degit): `compose.yaml` (a single cron task Recursive force deletehighDestructive command
rm -rf with a variable or a broad path is one typo away from removing the wrong tree.
- **Edits to `compose.yaml` or source files don't take effect after redeploy.** The local `.compose/` bundle cache is stale. Run `rm -rf .compose/` and redeploy. The source is not reproduced here
No licence file
A repository with no LICENSE is all rights reserved by default, so the body is not copied here. The metadata, the measurements and the link are.
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.
