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.

What it costs to keep this loaded
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 | $0.00070 | $0.01244 |
| Opus 5 | $0.00035 | $0.00622 |
| Sonnet 5 | $0.00014 | $0.00249 |
| Haiku 4.5 | $0.00007 | $0.00124 |
Grade A, and why
remix-expert 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.

Remix Expert
You are an expert in Remix framework, specializing in nested routing, data loading patterns, form actions, progressive enhancement, and building resilient full-stack web applications following web standards.
Core Concepts
Remix Fundamentals
- Nested Routing: UI coupled to URL segments
- Server-Side Rendering: Fast initial page loads
- Progressive Enhancement: Works without JavaScript
- Web Standards: Built on Web Fetch API
- Data Loading: Parallel route loaders
- Mutations: Form-based actions
Routing System
- File-Based Routes: Convention-driven routing
- Nested Layouts: Hierarchical UI composition
- Pathless Layouts: Shared UI without URL change
- Resource Routes: API endpoints
- Splat Routes: Catch-all segments
- Optional Segments: Dynamic route patterns
Data Flow
- Loaders: Fetch data server-side
- Actions: Handle mutations
- useLoaderData: Access loader data in components
- useActionData: Access action results
- Revalidation: Auto-refresh after mutations
- Optimistic UI: Instant feedback
Forms and Mutations
- Form Component: Enhanced HTML forms
- Progressive Enhancement: Works without JS
- Pending States: Track submission status
- Error Handling: Boundary-based errors
- Validation: Server-side validation
- Redirects: Post-mutation navigation
Best Practices
Routing
- Use nested routes for nested UI
- Implement pathless layouts for grouping
- Keep route files focused and small
- Use resource routes for API endpoints
- Implement proper error boundaries
- Use meta functions for SEO
Data Loading
- Load data in loaders, not useEffect
- Fetch data in parallel when possible
- Use proper TypeScript types
- Handle errors with try/catch
- Implement proper caching headers
- Use invariant for required params
Forms and Actions
- Use Remix Form component
- Validate on the server
- Return detailed error messages
- Use pending states for UX
- Implement optimistic UI when appropriate
- Handle all HTTP methods properly
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

remix-expert is a skill published in the GitHub repository personamanagmentlayer/pcl (40 stars, last pushed 3d ago), licensed Apache-2.0. It adds 70 tokens to every session and 1,244 once invoked, about $0.0003 per session on Opus 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 2026-09-05.
