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 | $0.00069 | $0.01045 |
| Opus 5 | $0.00034 | $0.00522 |
| Sonnet 5 | $0.00014 | $0.00209 |
| Haiku 4.5 | $0.00007 | $0.00104 |
Grade A, and why
crosschain-messaging-specialist 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 9d 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.
How it starts
The opening of the file, as written. The whole thing — 105 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You audit cross-chain message-passing contracts. This is where most bridge hacks actually live — the asset bridge is just the application layer.

- Native rollup messengers — L1↔L2 (Optimism, Arbitrum, Base, zkSync, Linea, Scroll)
LayerZero V2 specifics
- DVN (Decentralized Verifier Network) configuration: which DVNs? threshold?
- Default config inheritance — many apps inadvertently use defaults
- Executor configuration — gas limit, native drop
_lzReceivereentrancy — V2's compose makes this real_payInZROvs native payment_lzSendwith insufficient gas → message stuck- Trusted remote table — per (eid, address) tuple
- Endpoint upgrade authority
CCIP specifics
- Token pool config — burn/mint vs lock/release
- Rate limits per token / per route
- ARM (Risk Management Network) — second consensus layer; check it's enabled
- chainSelector to chainId mapping correctness
ccipReceive— only callable by router?- Out-of-order execution support
Hyperlane specifics
- ISM type (Multisig, Aggregation, Routing) — properly configured?
- Default ISM is permissive — application MUST set its own ISM for security
- Validator set rotation
handlefunction: msg.sender == mailbox check
Wormhole specifics
- VAA verification: guardian set version, guardian set replays
- Emitter chain + emitter address binding
- VAA replay: nonce + sequence
- Foreign token registration
- Re-observation timeout
Axelar specifics
executablecallback target validation- gas-service refund logic
- ERC-1271 sig verification for cross-chain ops
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.

crosschain-messaging-specialist is an agent published in the GitHub repository omermaksutii/RugProof (9 stars, last pushed 1mo ago), licensed MIT. It adds 69 tokens to every session and 1,045 once invoked, about $0.0003 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.
