ground-in-docs

ground-in-docs is a skill for Claude Code from lidonation/Cardano-mcp. It costs 74 tokens per session (669 once invoked), scanned A, original, MIT.

A reference-guidance skill for explaining Cardano, a blockchain platform, using the repository's curated documents about its transaction model, Aiken contracts, and governance.

In plain words
What is it for?
It helps explain eUTxO transactions, datums and redeemers, Aiken validator code, and Cardano voting roles such as DReps and the constitutional committee.
Why use it?
It reduces the risk of explanations drifting into outdated or generic blockchain advice. Answers are based on the project's own terminology and sources.

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

ground-in-docs 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 today.

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.

Ground concept answers in the repo's own docs

This repo ships three curated reference docs specifically so an agent's explanations of Cardano concepts stay accurate and consistent with how the cardano-mcp server itself models these ideas, rather than drifting toward generic, possibly-outdated blockchain explanations from general training data:

  • src/resources/eutxo-context.md — the eUTxO model: UTxOs, validators, datums vs redeemers, how balances work without accounts.
  • src/resources/governance-context.md — CIP-1694 / Conway-era governance: DReps, the constitutional committee, SPOs, the seven governance action types, treasury withdrawals, voting.
  • src/resources/aiken-stdlib.md — Aiken standard library reference used by the contracts module's tools (get_aiken_stdlib_docs, scaffold_validator, explain_eutxo_model).

Workflow

  1. Before answering a question about eUTxO mechanics, Aiken/validator concepts, or CIP-1694 governance, read the relevant file(s) above with the Read tool.
  2. Base the answer on what those docs actually say. If the docs and your general knowledge would suggest different framing or terminology, prefer the docs — they're what this project's own tools (explain_eutxo_model, the governance module, get_aiken_stdlib_docs) are aligned with, so answers should stay consistent with what the server itself would tell a caller.
  3. If the question goes beyond what these docs cover (e.g. a very specific protocol parameter, a recent CIP not yet reflected here, an Aiken language feature outside the stdlib doc), say so explicitly rather than quietly filling the gap from general knowledge — the point is to be honest about the boundary between "grounded in this project's docs" and "my general understanding."
  4. When these docs would benefit from an update (they're missing something a user needed), say so — don't silently patch the answer without flagging that the source doc could be extended.

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.

ground-in-docs is a skill published in the GitHub repository lidonation/Cardano-mcp (2 stars, last pushed yesterday), licensed MIT. It adds 74 tokens to every session and 669 once invoked, about $0.0004 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 2026-09-21.
