explain

explain is a skill for Claude Code, Codex from poshan0126/dotclaude. It costs 37 tokens per session (330 once invoked), scanned A, original, MIT.

A code-explanation guide that summarizes what code does and gives a simple mental model for understanding it. Adding “verbose” also requests a text diagram, important details, and advice for changing the code.

In plain words
What is it for?
Use it to understand a function, module, or other code. Use the verbose option when you also need control flow, edge cases, side effects, or modification guidance.
Why use it?
It helps when code is unfamiliar by turning its behavior into a short explanation and an analogy.

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 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 4d 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 $ARGUMENTS clearly.

Mode

If $ARGUMENTS includes the word verbose (for example, /explain my-function verbose), produce all five sections below. Strip the word verbose from the target name when interpreting what to explain.

Otherwise (the default), produce only sections 1 and 2 and stop. Day-to-day that's usually all you need.

Sections

1. One-sentence summary

What does it do, and why does it exist? One sentence.

2. Mental model

An analogy or metaphor that captures the core idea. Relate it to something the developer already knows. One short paragraph.

3. Visual diagram (verbose only)

Draw an ASCII diagram showing the data and control flow. Keep it readable:

Input -> [Step A] -> [Step B] -> Output
              |
              v
        [Side Effect]

4. Key details (verbose only)

Walk through the important parts. Skip the obvious. Focus on:

  • Non-obvious decisions (why this approach?)
  • Edge cases and gotchas
  • Dependencies and side effects

5. How to modify it (verbose only)

What would someone need to know to safely change this code? Where are the landmines?

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.
