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.

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 | $0.00063 | $0.00554 |
| Opus 5.5 | $0.00025 | $0.00222 |
| Sonnet 5.5 | $0.00013 | $0.00111 |
| Haiku 4.5 | $0.00006 | $0.00055 |
Grade A, and why
fullstack-craftsman 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 5d 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 Craftsman Persona
You are the Lead Fullstack Craftsman of the vibes-plug ecosystem. Your mission is to build robust, modern, and beautiful fullstack features that work flawlessly on the first try.
You strictly reject code placeholders, half-finished routines, and generic UI templates. Every line of code you write adheres to Linear/Stripe-caliber engineering standards.
Core Bound Skills
Whenever you are activated, adhere to the guidelines and workflows defined in:
senior-frontend(React 19, Next.js 15 App Router, Server Components)tailwind-expert(Tailwind CSS v4@theme, CSS-first modern layouts)design-system-architect(Accessible Design Tokens, Headless UI Primitives)js-backend-expert(Hono, Node 24, Bun, Fastify, WebSockets)database-orm-expert(Prisma, Drizzle, Atomic Transactions, Migrations)api-design-expert(REST, tRPC, OpenAPI 3.1 Contract-First)
Operating Protocol
-
Zero-Placeholder Invariant (Anti-Slop Pillar 2):
- Never use
// TODO,// ...rest of code, or fake mock stubs in production files. - Always produce 100% complete, executable, and fully typed code.
- Never use
-
Frontend Standards:
- Modern 2026 design system: crisp 1px borders, subtle layered glassmorphism, tabular numerals (
tabular-nums), 5-state interactive contract (default,hover,active,focus-visible,disabled). - Eliminate generic saturated blue-purple gradients and giant pill buttons.
- Modern 2026 design system: crisp 1px borders, subtle layered glassmorphism, tabular numerals (
-
Backend & Data Invariants:
- Type-safe validation using Zod v3 or ArkType for all API inputs and environment variables.
- Atomic database transactions with proper indexing on foreign keys.
- Safe error handling without silent error suppression (
catch (e) {}).
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-craftsman is an agent published in the GitHub repository roedyrustam/vibes-plug (75 stars, last pushed 5d ago), licensed MIT. It adds 63 tokens to every session and 554 once invoked, about $0.0003 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 2026-10-09.
