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.

SkillSpector: 7 findings, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- high Tool Misuse · line 233 Tool parameters are crafted to achieve unintended or unsafe behavior. Parameter abuse can bypass intended safety checks (e.g. shell=True, --force, dangerous glob patterns).Fix: Validate all tool parameters against an allowlist. Reject dangerous parameter values (shell=True, --force, -rf /) and use safe defaults.

- high Excessive Agency · line 291 Skill selects an external model or provider that may use a different account or billing plan than the operator expects. Undisclosed model switches can cause unexpected cost or quota consumption.Fix: Remove the model/provider override or disclose it prominently and require explicit operator approval before invoking an external coding CLI or billed model.
- medium Rogue Agent · line 29 Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.
- medium Excessive Agency · line 301 Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.
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 | $0.00014 | $0.02544 |
| Opus 5.5 | $0.00006 | $0.01018 |
| Sonnet 5.5 | $0.00003 | $0.00509 |
| Haiku 4.5 | $0.00001 | $0.00254 |
Grade A, and why
sonarqube scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 20d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.
**Important:** Direct curl with `-u "$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 (6,218 stars, last pushed today), 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 5.5. 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.

second-opinion
Cross-validate code, architecture or design decisions using a second model. Use for critical decisions, complex refactoring, security reviews.
code-review
A code-review procedure for checking whether changes meet their requirements, behave correctly, stay within safe boundaries, and have effective tests.
code-review-loop
Use when opening a PR for review or when receiving review feedback. Activate for keywords like "code review", "PR review", "request review", "review feedback", "address comments", "reviewer said". Covers both ends of the loop: preparing a reviewable PR and acting on feedback rigorously. Always engage with every…
aio-review-deep
Deep multi-agent code review — dispatch a fleet of parallel specialized agents (security, architecture, quality, performance) with GitNexus domain analysis. Use before merging a PR or after a major feature lands when a single-pass review is too shallow. For a quick pre-commit sanity check use aio-review-quick.
aio-map
Trace dependencies, call graphs, and blast radius for a file/function/module via GitNexus + LSP. Step 2 of the codeflow discover → map → plan trio (after aio-discover, before aio-plan).
