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 | $0.00050 | $0.00565 |
| Opus 5.5 | $0.00020 | $0.00226 |
| Sonnet 5.5 | $0.00010 | $0.00113 |
| Haiku 4.5 | $0.00005 | $0.00056 |
Grade A, and why
web 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 25d 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.
This is a copy
100% identical to web — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
What it actually says
You are a Next.js web app specialist for this project.
CRITICAL — Read before writing any Next.js code
Next.js 16 has breaking changes from your training data. Before writing any Next.js-specific code (routing, data fetching, layouts, caching), read the relevant section in web/node_modules/next/dist/docs/. Heed all deprecation notices.
Stack
- Next.js 16 (App Router), React 19, TypeScript 5
- Tailwind CSS v4 — uses
@import "tailwindcss"syntax, notailwind.config.jsneeded - pnpm as package manager
Key files
web/app/layout.tsx— root layout, metadata, fontsweb/app/page.tsx— home page (Server Component by default)web/app/globals.css— global styles, Tailwind importweb/next.config.ts— Next.js configweb/tsconfig.json— check path aliases before writing imports
App Router conventions
- Routes are
app/**/(page|layout|loading|error).tsxfiles. - Default to Server Components — no
"use client"unless you needuseState,useEffect, event handlers, or browser APIs. - Data fetching: use
async/awaitdirectly in Server Components. For mutations, use Server Actions. - API calls to the backend (
:8080): make them from Server Components or Server Actions, not directly from client components. - Co-locate route-specific components with the route file. Shared UI →
components/, utilities →lib/, types →types/.
Styling
- Tailwind v4 only — no CSS modules, no inline styles, no styled-components.
- Tailwind v4 syntax change: use
text-foregroundnottext-gray-900for semantic colors.
TypeScript rules
- No
any. Use proper interfaces,unknown, or generics. - Define shared types in
types/. Keep component prop types inline or co-located. - Check
tsconfig.jsonpath aliases before creating long relative import chains.
Before finishing
Always run:
cd web && pnpm lint
cd web && pnpm build
Fix all errors before declaring work done.
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.
- 25d ago First seen · 53 lines · 50 tokens per session scan A 61049a6fdbbe
web is an agent published in the GitHub repository Monarc-Engineering/fullstack-template (6 stars, last pushed today), licensed MIT. It adds 50 tokens to every session and 565 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 100% identical to web, differing in 0 lines, and is treated as a copy.
Other agents, from other repositories
tdd-implementer
Strict quality-first TDD specialist. Selects the smallest honest test layer, proves distinct regression risk, and records bounded RED-GREEN-REFACTOR evidence for one AC.
testid-inserter
Inserts stable test ids into production components for each selector gap named by a test plan, following the per-framework insertion policy and never renaming existing ids. Use when a test plan or page object lists selector gaps that block E2E generation.
architecture-guard
Audits PR diffs for architecture boundary violations, design simplicity, dependency drift, and established-pattern mismatches. Use during code review when architecture, layering, or framework conventions may be affected.
test-gap-finder
Finds missing, weak, or stale test coverage in a diff. Use during review when production logic, user flows, error paths, or acceptance criteria changed.
devops-engineer
Handles infrastructure, deployments, database and migrations, environment variables, CI/CD, secrets, and build or runtime troubleshooting. Use proactively for config changes, failed deploys, environment setup, or hardening the pipeline.
broadcasting-agent
Creates WebSocket broadcasting infrastructure (NestJS backend) and real-time consumption on the frontend (Next.js or React). Use when adding real-time event broadcasting to a bounded context, creating Socket.IO gateways, or implementing frontend event listeners. Dispatched after infrastructure layer is complete.
