explain-code

explain-code is a command for Claude Code from solanabr/solana-ai-kit. It costs 13 tokens per session (295 once invoked), scanned A, original, MIT.

A code-explanation guide for Solana, a blockchain platform, and its Anchor programs. It turns complex code into plain-language steps, diagrams, and explanations of unfamiliar concepts.

In plain words
What is it for?
Use it to explain Solana instructions, client code, account structures, and tests, including concepts such as PDAs and CPIs.
Why use it?
It helps readers understand what blockchain code does and why it is written that way without having to decode every unfamiliar concept alone.

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

explain-code 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 25d 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 actually says

Explain the code in $ARGUMENTS (a path, symbol, or pasted snippet). Match depth to the code and the asker: a helper gets a paragraph; an instruction handler or a whole program gets the structure below.

For concept background, open the matching entry in SKILL.md. For tutorials or learning paths, hand off to the solana-guide agent.

Output

  1. Overview: what it does and why it exists, in two or three sentences.
  2. Diagram: Mermaid. A sequence diagram or flowchart for instruction and CPI flow, a graph for account and PDA relationships.
  3. Walkthrough: the significant sections in order, with the reasons behind non-obvious choices (seed layout, account order, bump handling, remaining_accounts).
  4. Solana concepts used: PDAs, CPIs and signer seeds, rent, account ownership, Token vs Token-2022; a sentence or two each on how this code uses them.
  5. Security notes: the checks the code performs and any it appears to miss (signer, owner, PDA, CPI target, arithmetic). For a real review, suggest /audit-solana.
  6. Check questions (for learners only): two or three "what happens if..." questions.

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.
