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 | $0.02098 | $0.02098 |
| Opus 5.5 | $0.00839 | $0.00839 |
| Sonnet 5.5 | $0.00420 | $0.00420 |
| Haiku 4.5 | $0.00210 | $0.00210 |
Grade A, and why
frontend-production-engineer AGENTS.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 18d 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 — 168 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md
This repository is a frontend engineering skill. Its canonical instructions
live in SKILL.md, which routes to the domain files under references/. Any
agent working in this repo should load SKILL.md first and then read only the
references/*.md file(s) relevant to the task.
Primary integration: Claude (Anthropic Agent Skills). The files below let
other agents use the same content; they are pointers, not copies. If anything
here disagrees with SKILL.md, SKILL.md wins.
Self-improvement
If this skill's text or script caused a mistake, or you had to find a step
yourself, record it at once. Before you claim the task is done, end the report
with Skill defects:. Section 0 of SELF-IMPROVEMENT.md gives the rules. If
~/.skill-improvements/frontend-production-engineer/ exists, do section 3
first.
What this skill does
Plans, writes, and reviews production Next.js and TypeScript against a Django / Django REST Framework backend. Scope is the browser-facing application. That scope is routing and rendering, the React component tree, and the typed contract with the backend. It also holds the non-functional guarantees a shipped frontend owes its users. The Django backend itself is out of scope. Server-side security defers to the backend's own security review.
Twenty-four domains are integrated across four tiers. The tiers are foundations, backend contract and state, interface craft, and non-functional guarantees. A Tier 0 operating doctrine sits under them, and it is always in effect.
The integrated material in references/ is the App Router
foundation, the type system, and the React component tree. It also holds the
project structure, the DRF contract, and the client cache and state.
It holds the session with the gates over it, and the push transport with the
events on it. It holds the design system and accessibility — the tokens and the
layout, the element and its name, the keyboard, and the measurable criteria.
It holds forms, the dense data surface, media, and motion. That part is the schema and the bind, and the table with the server that drives it. It also holds the file that leaves for a user, and the animation over all of them.
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.

frontend-production-engineer AGENTS.md is an instructions file published in the GitHub repository n-shadloo/frontend-production-engineer (2 stars, last pushed 4d ago), licensed MIT. It adds 2,098 tokens to every session, about $0.0084 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.
