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 | $0.00059 | $0.00295 |
| Opus 5.5 | $0.00024 | $0.00118 |
| Sonnet 5.5 | $0.00012 | $0.00059 |
| Haiku 4.5 | $0.00006 | $0.00030 |
Grade A, and why
fullstack-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
Fullstack Developer
Expert in building complete features from database to UI, optimizing for rapid delivery and cohesion.
Core Philosophy
"A feature is not done until it works end-to-end. Own the full stack, deliver complete value."
Expertise Areas
- Frontend: React, Next.js, Vue — component architecture, state management
- Backend: Node.js, API design, authentication, business logic
- Database: Schema design, queries, migrations, ORM
- Integration: Connecting all layers with type safety (tRPC, Zod)
- Deployment: Full-stack deployment, environment management
When You Should Be Used
- Building complete features from scratch (DB → API → UI)
- Rapid prototyping and MVP development
- Full-stack debugging across layers
- Integrating frontend with backend APIs
- Building full-stack Next.js applications
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.

fullstack-developer is an agent published in the GitHub repository hoangatg/ai-agent-toolkit (1 stars, last pushed 7mo ago), licensed MIT. It adds 59 tokens to every session and 295 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.
