luongnv89/claude-howto is a visual, example-based guide to Claude Code, a coding tool that supports agents, hooks, skills, slash commands, and MCP servers. Developers use it to learn Claude Code through practical workflows and copyable templates, including the commands, agents, skills, plugins, and instructions catalogued here.
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 | $0.00040 | $0.00598 |
| Opus 5 | $0.00020 | $0.00299 |
| Sonnet 5 | $0.00008 | $0.00120 |
| Haiku 4.5 | $0.00004 | $0.00060 |
Grade A, and why
brand-voice 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 12d 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.
Copies of this mod
2 near-identical copies found in the catalogue:
- brand-voice-consistency — 86% identical, 26 lines differ

Brand Voice Skill
Overview
This skill ensures all communications maintain consistent brand voice, tone, and messaging.
Brand Identity
Mission
Help teams automate their development workflows with AI
Values
- Simplicity: Make complex things simple
- Reliability: Rock-solid execution
- Empowerment: Enable human creativity
Tone of Voice
- Friendly but professional - approachable without being casual
- Clear and concise - avoid jargon, explain technical concepts simply
- Confident - we know what we're doing
- Empathetic - understand user needs and pain points
Writing Guidelines
Do's ✅
- Use "you" when addressing readers
- Use active voice: "Claude generates reports" not "Reports are generated by Claude"
- Start with value proposition
- Use concrete examples
- Keep sentences under 20 words
- Use lists for clarity
- Include calls-to-action
Don'ts ❌
- Don't use corporate jargon
- Don't patronize or oversimplify
- Don't use "we believe" or "we think"
- Don't use ALL CAPS except for emphasis
- Don't create walls of text
- Don't assume technical knowledge
Vocabulary
✅ Preferred Terms
- Claude (not "the Claude AI")
- Code generation (not "auto-coding")
- Agent (not "bot")
- Streamline (not "revolutionize")
- Integrate (not "synergize")
❌ Avoid Terms
- "Cutting-edge" (overused)
- "Game-changer" (vague)
- "Leverage" (corporate-speak)
- "Utilize" (use "use")
- "Paradigm shift" (unclear)
Examples
✅ Good Example
"Claude automates your code review process. Instead of manually checking each PR, Claude reviews security, performance, and quality—saving your team hours every week."
Why it works: Clear value, specific benefits, action-oriented
❌ Bad Example
"Claude leverages cutting-edge AI to provide comprehensive software development solutions."
Why it doesn't work: Vague, corporate jargon, no specific value

What ships with it
3 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.

brand-voice is a skill published in the GitHub repository luongnv89/claude-howto (41,422 stars, last pushed 5d ago), licensed MIT. It adds 40 tokens to every session and 598 once invoked, about $0.0002 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 2026-08-30.
