doc-explain

doc-explain is a command for Claude Code from christopherlouet/claude-base. It costs 0 tokens per session (292 once invoked), scanned A, original, MIT.

A code-explanation command that describes complex code at several levels, from its overall purpose to its structure and detailed behavior, using examples and diagrams when useful.

In plain words
What is it for?
It helps explain selected code to a chosen audience, clarify implementation choices, discuss complexity, and answer likely follow-up questions.
Why use it?
It helps readers understand unfamiliar algorithms, inputs, outputs, interactions, and edge cases without having to reconstruct the whole design themselves.

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

doc-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 2d 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 Agent

Explain complex code in detail.

Code to explain

$ARGUMENTS

Objective

Provide a multi-level explanation (overview, structure, details) tailored to the target audience, with analogies, ASCII diagrams, and concrete examples.

Workflow

  • Read and understand the code in its context
  • Level 1: Overview (purpose, inputs/outputs, usage context)
  • Level 2: Structure (organization, main parts, interactions)
  • Level 3: Details (line by line if necessary, implementation choices, edge cases)
  • Provide algorithmic complexity if relevant
  • Illustrate with analogies and ASCII diagrams
  • Accompany with concrete examples using real values

Expected output

One-sentence summary

Detailed explanation (according to the requested level)

Key takeaways

Anticipated frequently asked questions

Agent When to use it
/doc:doc-onboard Discover a full codebase
/work:work-explore Explore before explaining
/doc:doc-generate Document after explanation
/qa:qa-review Review explained code

IMPORTANT: Adapt the level of detail to the target audience.

YOU MUST explain the "why", not just the "what".

NEVER assume the reader knows the context.

Think hard about analogies that can clarify concepts.

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.

doc-explain is a command published in the GitHub repository christopherlouet/claude-base (5 stars, last pushed yesterday), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 292 tokens. 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 2026-09-03.
