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
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.

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 5.1 | $0.00043 | $0.01730 |
| Opus 5.5 | $0.00017 | $0.00692 |
| Sonnet 5.5 | $0.00009 | $0.00346 |
| Haiku 4.5 | $0.00004 | $0.00173 |
Grade A, and why
plan-pipeline-execute 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 18d 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.

plan-pipeline-execute is a skill published in the GitHub repository FlorianBruniaux/claude-code-ultimate-guide (6,204 stars, last pushed today), licensed CC-BY-SA-4.0. It adds 43 tokens to every session and 1,730 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-09-03.

tdd
Build this test-first, one behavior at a time: $ARGUMENTS.
test-first
Use when implementing any feature, bugfix, or refactor that has a testable outcome. Activate for keywords like "TDD", "test-first", "red-green", "write the test first", "implement ", "fix ". Enforces the red-green-refactor discipline -- write a failing test, make it pass with the smallest change, refactor with tests…
aio-gherkin-refine
Comprehensive BDD field guide for writing and reviewing Gherkin scenarios with expert quality. Use proactively when a request is ambiguous, spans multiple conditions, or edge cases need clarification.
testing
Testing strategies and methodologies including TDD and E2E testing. Use when writing tests, implementing TDD workflow, or setting up E2E test infrastructure.
agent-test-generator
Specialist subagent: Generates comprehensive test suites using TDD patterns. Use only when the user explicitly asks for tests, improved coverage, or test-first development.
