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.

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 | $0.00144 | $0.00529 |
| Opus 5 | $0.00072 | $0.00264 |
| Sonnet 5 | $0.00029 | $0.00106 |
| Haiku 4.5 | $0.00014 | $0.00053 |
Grade A, and why
claude-code-guide 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 2d 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 Advanced Guide
A comprehensive guide to maximizing Claude Code productivity, combining community-proven patterns from The Longform Guide to Everything Claude Code by @affaanmustafa with official Anthropic documentation.
How to Use This Skill
This skill is organized into topic-specific reference files. Read only the file relevant to the user's question:
| Topic | Reference File | When to Read |
|---|---|---|
| Token optimization & model selection | references/token-optimization.md |
Questions about reducing costs, choosing models for subagents, replacing MCPs with CLI |
| Context & memory management | references/context-memory.md |
Questions about CLAUDE.md, auto memory, session persistence, context clearing, compaction |
| Subagent best practices | references/subagents.md |
Questions about orchestrating subagents, context isolation, iterative retrieval, sequential phases |
| Parallelization strategies | references/parallelization.md |
Questions about running multiple Claude instances, git worktrees, cascade method, fan-out |
| Verification & evals | references/verification-evals.md |
Questions about testing, verification loops, pass@k vs pass^k, benchmarking skills |
| Environment setup | references/environment-setup.md |
Questions about configuring permissions, hooks, skills, MCP, CLI tools, plugins |
| Workflow patterns & tips | references/workflow-patterns.md |
Questions about planning workflows, continuous learning, project kickoff, practical tips |
| Agentic security | references/agentic-security.md |
Questions about agent security, prompt injection, sandboxing, attack vectors, CVEs, kill switches, sanitization |
Read the relevant reference file(s) before answering. Do NOT load all files at once — only load what the user's question requires.
What ships with it
8 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

claude-code-guide is a skill published in the GitHub repository ByeongminLee/nextjs-claude-code (3 stars, last pushed 5mo ago), licensed MIT. It adds 144 tokens to every session and 529 once invoked, about $0.0007 per session on Opus 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 2026-08-31.
