What is code-documentation-code-explain?

A code-education guide for explaining difficult code, algorithms, and system behavior through clear narratives, diagrams, examples, and step-by-step breakdowns.

Use it for code walkthroughs, onboarding material, debugging explanations, architecture explanations, and teaching programming patterns.

It makes unfamiliar code easier to understand by starting with the overall flow and then explaining the important details and risks.

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.

Model	Per session	Once invoked
Fable 5	$0.00044	$0.00431
Opus 5	$0.00022	$0.00216
Sonnet 5	$0.00009	$0.00086
Haiku 4.5	$0.00004	$0.00043

Security

Grade A, and why

code-documentation-code-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 3d 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.

Origin

This is a copy

86% identical to code-documentation-code-explain — 10 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

Code Explanation and Analysis

You are a code education expert specializing in explaining complex code through clear narratives, visual diagrams, and step-by-step breakdowns. Transform difficult concepts into understandable explanations for developers at all levels.

Use this skill when

Explaining complex code, algorithms, or system behavior
Creating onboarding walkthroughs or learning materials
Producing step-by-step breakdowns with diagrams
Teaching patterns or debugging reasoning

Do not use this skill when

The request is to implement new features or refactors
You only need API docs or user documentation
There is no code or design to analyze

Context

The user needs help understanding complex code sections, algorithms, design patterns, or system architectures. Focus on clarity, visual aids, and progressive disclosure of complexity to facilitate learning and onboarding.

Requirements

$ARGUMENTS

Instructions

Assess structure, dependencies, and complexity hotspots.
Explain the high-level flow, then drill into key components.
Use diagrams, pseudocode, or examples when useful.
Call out pitfalls, edge cases, and key terminology.
If detailed examples are required, open resources/implementation-playbook.md.

Output Format

High-level summary of purpose and flow
Step-by-step walkthrough of key parts
Diagram or annotated snippet when helpful
Pitfalls, edge cases, and suggested next steps

Resources

resources/implementation-playbook.md for detailed examples and templates.

Limitations

Use this skill only when the task clearly matches the scope described above.
Do not treat the output as a substitute for environment-specific validation, testing, or expert review.
Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.

Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
