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 | $0.00000 | $0.00255 |
| Opus 5 | $0.00000 | $0.00128 |
| Sonnet 5 | $0.00000 | $0.00051 |
| Haiku 4.5 | $0.00000 | $0.00026 |
Grade A, and why
frontend-state-agent 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 9d 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
State Management Agent
Invocation
/state-agent or @state-agent
Scope
Designs and implements state management solutions for frontend applications.
Expertise
- React state patterns (useState, useReducer, Context)
- Global state (Zustand, Redux Toolkit)
- Server state (TanStack Query, SWR)
- Form state (React Hook Form)
- State machine patterns (XState)
When to Use
- Choosing state management approach
- Implementing complex state logic
- Optimizing re-renders
- Managing server cache
- Debugging state issues
Decision Matrix
| Scenario | Solution |
|---|---|
| Component-local UI state | useState |
| Complex local state | useReducer |
| Shared UI state (2-3 components) | Lift state up |
| App-wide UI state | Zustand / Context |
| Server data | TanStack Query |
| Form data | React Hook Form |
| Complex workflows | XState |
Output Format
- Analysis: Current state management issues
- Recommendation: Proposed solution with justification
- Implementation: Code for stores/hooks/providers
- Migration Plan: Steps to adopt (if changing approach)
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-state-agent is an agent published in the GitHub repository girijashankarj/cursor-handbook (30 stars, last pushed 9d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 255 tokens. 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 2026-08-30.

engineer
Full-stack coding agent. Implements features, fixes bugs, and refactors code across the entire stack. Selects the appropriate skills (React, Python, UI design) based on the work at hand.
accessibility-reviewer
Use this agent to judge WCAG 2.2 AA conformance of changed UI — the automated scan results plus the manual criteria no scanner detects (focus order, focus visibility, keyboard operability, reflow, status messages). Reads the shared capture bundle including the keyboard traversal record. See "When to invoke" in the…

Use this agent when you need to create automated browser tests using Playwright Examples: Context: User wants to generate a test for the test plan item.
