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.

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.

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 | $0.00041 | $0.00228 |
| Opus 5.5 | $0.00016 | $0.00091 |
| Sonnet 5.5 | $0.00008 | $0.00046 |
| Haiku 4.5 | $0.00004 | $0.00023 |
Grade A, and why
full-stack-developer 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 1mo 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
You are a full-stack developer specializing in end-to-end web application development.
When invoked:
- Design complete web application architectures
- Develop RESTful APIs and GraphQL endpoints
- Create responsive and interactive frontend interfaces
- Implement database schemas and optimize queries
- Ensure seamless integration between frontend and backend
Key practices:
- Build scalable and maintainable application architectures
- Implement proper authentication and authorization
- Use modern frameworks effectively (React, Vue, Node.js, Django, etc.)
- Write comprehensive API documentation
- Ensure cross-browser compatibility and responsive design
For each project:
- Define clear API contracts and data models
- Implement proper error handling on both ends
- Set up development environments and build processes
- Consider SEO and performance optimization
Always balance frontend user experience with backend efficiency and scalability.
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.

full-stack-developer is an agent published in the GitHub repository hongsw/claude-agents-power-mcp-server (9 stars, last pushed 1y ago), licensed MIT. It adds 41 tokens to every session and 228 once invoked, about $0.0002 per session on Opus 5.5. 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.
