Claude Code: Everything You Need to Know is a practical guide to using Claude Code, an AI coding assistant that can be extended with commands, skills, hooks, subagents, workflows, and external tool servers. Developers use it to learn Claude Code from basic prompting through team and automation setups. The catalogue entries are examples of the guide's Claude Code extensions and workflows.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 5.1 | $0.00015 | $0.00374 |
| Opus 5 | $0.00008 | $0.00187 |
| Sonnet 5 | $0.00003 | $0.00075 |
| Haiku 4.5 | $0.00002 | $0.00037 |
Grade A, and why
five 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 8d 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
Five Whys Analysis
Apply the Five Whys root cause analysis technique to investigate issues.
Description
This command implements the Five Whys problem-solving methodology, iteratively asking "why" to drill down from symptoms to root causes. It helps identify the fundamental reason behind a problem rather than just addressing surface-level symptoms.
Usage
five [issue_description]
Variables
- ISSUE: The problem or symptom to analyze (default: prompt for input)
- DEPTH: Number of "why" iterations (default: 5, can be adjusted)
Steps
- Start with the problem statement
- Ask "Why did this happen?" and document the answer
- For each answer, ask "Why?" again
- Continue for at least 5 iterations or until root cause is found
- Validate the root cause by working backwards
- Propose solutions that address the root cause
Examples
Example 1: Application crash analysis
Problem: Application crashes on startup
Why 1: Database connection fails
Why 2: Connection string is invalid
Why 3: Environment variable not set
Why 4: Deployment script missing env setup
Why 5: Documentation didn't specify env requirements
Root Cause: Missing deployment documentation
Example 2: Performance issue investigation
Systematically trace why a feature is running slowly by examining each contributing factor.
Notes
- Don't stop at symptoms; keep digging for systemic issues
- Multiple root causes may exist - explore different branches
- Document each "why" for future reference
- Consider both technical and process-related causes
- The magic isn't in exactly 5 whys - stop when you reach the true root cause
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.

five is a command published in the GitHub repository wesammustafa/Claude-Code-Everything-You-Need-to-Know (2,969 stars, last pushed 1mo ago), licensed MIT. It adds 15 tokens to every session and 374 once invoked, about $0.0001 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 2026-08-30.
Other commands, from other repositories
fix-issue
A command that takes a GitHub Issue—a tracked bug, request, or question—and guides its fix from investigation through testing and submission. TDD means writing a failing test first, then changing the code until the test passes.
hotfix
An emergency software-fix workflow that moves directly from development to verification and Git commit, skipping the usual planning and design stages.
cleanup
A cleanup command that finds code, files, and dependencies that appear to be unused, then removes only items confirmed to be unnecessary.
fix
A command for fixing build, type-checking, and compilation errors with only the smallest necessary code changes. It covers common issues such as missing types, invalid imports, null values, configuration errors, and missing dependencies.
