Token cost

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.

Security

Grade A, and why

happy-claude-skills AGENTS.md 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 11d 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

AGENTS.md

This repository provides a collection of practical skills for AI coding agents. Skills are packaged as SKILL.md files with accompanying scripts, compatible with any agent that supports the skills ecosystem.

Available Skills

1password Manage passwords and API credentials with 1Password CLI (op)
browser Browser automation via Chrome DevTools Protocol
docx-format-replicator Extract and replicate Word document formatting
trends-bulletin Multi-platform trending topics bulletin (6 platforms → Telegram)
video-processor Download, convert, and transcribe videos
wechat-article-writer Automated WeChat article writing workflow

Skill Format

Each skill lives in skills/<name>/ and contains:

  • SKILL.md — Frontmatter (name, description) + instructions
  • scripts/ — Executable scripts (bash, python, node, bun)

Installation

# Install via skills CLI (works with Claude Code, Codex, Droid, OpenClaw, Cursor, and 40+ agents)
npx skills add iamzhihuix/happy-claude-skills

# Install specific skills
npx skills add iamzhihuix/happy-claude-skills --skill browser --skill 1password

# Install to a specific agent
npx skills add iamzhihuix/happy-claude-skills --agent codex
npx skills add iamzhihuix/happy-claude-skills --agent droid
npx skills add iamzhihuix/happy-claude-skills --agent openclaw

Contributing

When creating or modifying skills:

  1. Each skill must have a SKILL.md with YAML frontmatter containing name and description
  2. Scripts should be executable and self-contained
  3. Document all dependencies in the SKILL.md
  4. Use relative paths from the skill directory for scripts
Changes

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.
