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.

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 | $0.00014 | $0.02544 |
| Opus 5 | $0.00007 | $0.01272 |
| Sonnet 5 | $0.00003 | $0.00509 |
| Haiku 4.5 | $0.00001 | $0.00254 |
Grade A, and why
sonarqube scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.
**Important:** Direct curl with `-u "$SONARQUBE_TOKEN:"` fails in zsh due to authentication parsing. Use bash script wrapper: The source is not reproduced here

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.

sonarqube is a skill published in the GitHub repository FlorianBruniaux/claude-code-ultimate-guide (5,903 stars, last pushed yesterday), licensed CC-BY-SA-4.0. It adds 14 tokens to every session and 2,544 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.

Review Go code with a defect-first approach using repository policy (constitution.md first, then AGENTS.md fallback). Use for code review, PR review, quality checks, risk analysis, and regression detection.
go-review-lead
Orchestrate a comprehensive Go code review by triaging code changes, dispatching vertical review skills (security, concurrency, error, logic, performance, quality, test, observability) as parallel agents, then consolidating results into a unified report.

Trigger when code contains go func, channels, sync primitives, WaitGroup, errgroup, or goroutine lifecycle management. Use for concurrency-focused review of…
go-error-review
Review Go code for error handling correctness, nil safety, and failure-path integrity including ignored errors, missing wrapping, panic misuse, SQL/HTTP resource lifecycle, and transaction patterns. Trigger when code contains error returns, panic calls, sql.Rows, transactions, HTTP client/server code, or nil-sensitive…
go-observability-review
Review Go code for observability gaps: missing structured logging, broken trace context propagation, Prometheus cardinality explosions, span lifecycle errors, and sensitive fields in logs. Dispatched by go-review-lead as a vertical reviewer. Also trigger directly when the user says "review my logging", "check my…
