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.

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 | $0.00295 | $0.00295 |
| Opus 5.5 | $0.00118 | $0.00118 |
| Sonnet 5.5 | $0.00059 | $0.00059 |
| Haiku 4.5 | $0.00030 | $0.00030 |
Grade A, and why
Claude-Code-Everything-You-Need-to-Know CLAUDE.md 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 5d 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

Claude Code notes
- When you edit this guide, load the bundled
/claude-apiskill before you state a model fact, then confirm the fact on its Tier 1 source from the table inAGENTS.md. The guide states no prices or plan limits. - This repo's root
.claude/holds no hooks and no allow rules: only a deny rule for reading.envfiles, a skill and a workflow (SECURITY.md).examples/is inert until copied; review every file before copying it. Never add a.claude/,CLAUDE.md,AGENTS.md,.mcp.jsonor.claude-plugin/marketplace.jsonunderexamples/: a marketplace manifest goes indot-claude-plugin/, so neither the example's folder nor this repo can be added as a plugin marketplace by its folder path or asowner/repo.

Issue tracker
For ticket and spec work, use private local Markdown under .scratch/. Read Issue tracker.
Triage labels
Use the default triage roles. Read Triage labels when triaging tickets.
Domain docs
Use a single-context layout. Read Domain docs before exploring the repo.
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.
