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 | $0.00795 | $0.00795 |
| Opus 5 | $0.00398 | $0.00398 |
| Sonnet 5 | $0.00159 | $0.00159 |
| Haiku 4.5 | $0.00080 | $0.00080 |
Grade A, and why
red-team-agent-skills CLAUDE.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.
How it starts
The opening of the file, as written. The whole thing — 87 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Installation & Setup
1. Skill Installation
Option A: Project-Local Use (Recommended for Development)
You can use the skills directly from this repository without global installation.
- Open this directory in Claude Code:
claude(from the root of this repo). - The skills in
.claude/skills/(red-team, agent-proxy) will be automatically loaded.
Option B: Global Installation
To use these skills globally across any project:
- Create the global skills directory:
mkdir -p ~/.claude/skills - Copy the skills:
cp -r .claude/skills/red-team ~/.claude/skills/ cp -r .claude/skills/agent-proxy ~/.claude/skills/
Optional: Claude Reflect (Self-Learning)
You can install claude-reflect to capture learnings and update CLAUDE.md automatically.
# Clone and install claude-reflect
git clone https://github.com/BayramAnnakov/claude-reflect ~/.claude/skills/claude-reflect
# Note: No pip requirements for this skill (uses standard library)
2. Dependencies
Install Python dependencies (required for red-team and agent-proxy):
pip install -r .claude/skills/red-team/requirements.txt
pip install -r .claude/skills/agent-proxy/requirements.txt
3. Browser Automation Setup (Required for Web UIs)
For testing Web UI agents (like ChatGPT, Claude, custom UIs), you must install one of the browser automation skills.
Option A: dev-browser (Recommended)
This skill provides persistent sessions (cookies/storage), better stealth, and profile management.
Install via MCP (recommended):
Check if dev-browser is available in your MCP configuration.
Install manually:
If you have access to the dev-browser repository:
# Clone and install dev-browser skill
git clone https://github.com/SawyerHood/dev-browser.git ~/.claude/skills/dev-browser
cd ~/.claude/skills/dev-browser
# Follow installation instructions in its README (usually npm install & build)
Option B: playwright-skill (Alternative)
Standard Playwright automation. Use this if dev-browser is not available.
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.

red-team-agent-skills CLAUDE.md is an instructions file published in the GitHub repository yechao-zhang/red-team-agent-skills (5 stars, last pushed 7mo ago), licensed MIT. It adds 795 tokens to every session, about $0.0040 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.
