Claude Code Ultimate Guide is a structured documentation project for learning how to build, operate, and govern coding agents with Claude Code. It serves developers and teams through guidance on agentic workflows, hooks, skills, MCP servers, security, and adoption. The catalogue entries are reusable skills, commands, agents, hooks, instructions, settings, and a plugin drawn from the guide's workflow materials.
Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00000 | $0.00462 |
| Opus 5 | $0.00000 | $0.00231 |
| Sonnet 5 | $0.00000 | $0.00092 |
| Haiku 4.5 | $0.00000 | $0.00046 |
Grade A, and why
update-threat-db 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 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.

update-threat-db is a command published in the GitHub repository FlorianBruniaux/claude-code-ultimate-guide (5,909 stars, last pushed yesterday), licensed CC-BY-SA-4.0. It costs nothing until one of its globs matches a file; then it loads 462 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 2026-08-30.
Other commands, from other repositories
designer
A UI and user-experience review role that turns a technical plan into guidance for an attractive, distinctive interface. It defines visual direction and advises on colour, typography, layout, responsiveness, accessibility, and component systems.
evolve
A knowledge-review workflow that groups repeated lessons and turns them into reusable commands, automatic skills, or separate agents. A command is user-triggered, a skill is an automatic behaviour, and an agent handles a complex multi-step task.
stocktake
A command for auditing a collection of reusable agent components, such as skills, rules, and commands. It reviews their structure, freshness, usage, and overlap, then suggests whether to keep or maintain them.
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.
build
A project-building command that detects the programming language and runs the matching build or compile command, then reports problems.
