chainlink-ccip-skill

chainlink-ccip-skill is a skill for Claude Code, Codex from smartcontractkit/chainlink-agent-skills. It costs 91 tokens per session (2,193 once invoked), scanned A, original, MIT.

A guide for Chainlink CCIP, a system for sending messages and tokens between blockchains. It covers read-only lookups, fee guidance, user-run transaction instructions, and development of sender and receiver contracts.

In plain words
What is it for?
Use it to look up routes, tokens, message status, lanes, fees, and configuration; prepare cross-chain transfer or messaging steps; and get guidance for CCIP contracts and setup.
Why use it?
It keeps blockchain actions within defined safety limits: it can inspect information and prepare artifacts, but it does not sign, broadcast, deploy, bridge, or execute on-chain writes. It routes each request to the simplest suitable procedure.

SkillSpector: 2 findings, up to high

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

  • high Privilege Escalation · line 57
    Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.
    Fix: Remove references to credential paths. Use environment variables or secrets managers. For docs, use placeholder paths (e.g., /path/to/config). Never load .env or token files in production code paths.
  • medium Excessive Agency · line 58
    Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.
    Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

chainlink-ccip-skill 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 8d 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.

Overview

Route CCIP requests to the simplest valid path while keeping side effects and credential exposure out of the agent runtime.

Perform live read-only lookups and generate user-run artifacts, but never sign, broadcast, deploy, bridge, transfer, or otherwise execute an onchain write. Refuse every mainnet write workflow, including user-run write artifacts.

Progressive Disclosure

  1. Keep this file as the default guide.
  2. Read references/examples.md only when you need a concrete reference for what a good response looks like (preflight summaries, monitoring explanations, contract-generation structure).
  3. Read references/official-sources.md only when the answer depends on live CCIP facts, current tool behavior, route or token availability, or message-status surfaces.
  4. Read references/ccip-api.md whenever the answer depends on live CCIP data: message status, lane inventory, lane latency, chain or contract configuration, verifiers, or intent status.
  5. Read references/ccip-tools.md only when the user wants a tool-first workflow through CCIP CLI, API, or SDK.
  6. Read references/ccip-contracts.md only when the user wants sender or receiver contracts, token-transfer contracts, programmable token-transfer contracts, or contract setup help.
  7. Read references/ccip-cct.md only when the user wants to create a token, register it as a CCT, configure pools, set rate limits, or add networks for CCT operation.
  8. Read references/chainlink-local.md only when the user wants local simulation, local tests, or forked-environment testing for CCIP contracts.
  9. Read references/ccip-monitoring.md only when the user wants message lookup, monitoring, status explanation, lane performance, or failed-message diagnosis.
  10. Read references/ccip-discovery.md only when the user wants route connectivity checks, network classification, or supported-token discovery.
  11. Read references/ccip-solidity-examples.md only when generating or reviewing CCIP Solidity contracts and you need concrete code patterns (sender, receiver, token transfer, defensive receiver).
  12. Read references/ccip-sdk-examples.md only when the user wants TypeScript SDK usage examples for fee estimation, token transfers, messaging, or status checks.
  13. Read references/ccip-non-evm.md only when the user wants to work with CCIP on Solana, Aptos, Sui, TON, Canton, or any non-EVM chain family.
  14. Do not load reference files speculatively.

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.
