cardano-status-codes

cardano-status-codes is a plugin for Claude Code from lidonation/Cardano-mcp. Its manifest loads nothing; the 1 skill it bundles cost 55 tokens per session together, scanned A, original, MIT.

A catalog of error messages produced by Cardano tools and their likely causes. It covers service responses, data-decoding failures, and blockchain transaction rejections.

In plain words
What is it for?
It helps interpret errors from Blockfrost, Koios, Maestro, Kupo, CBOR decoding, Plutus data, and rejected transaction submissions.
Why use it?
It turns vague failures into specific diagnosis and suggested fixes instead of encouraging blind retries or guesses.

Security

Grade A, and why

cardano-status-codes 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 1mo 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 installs

The manifest is a name and a version. 1 skill travel with it, and installing the plugin installs all of them — 55 tokens a session between them. Each is measured on its own page, and each can be installed alone.

Changes

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.
