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 | $0.00000 | $0.00572 |
| Opus 5.5 | $0.00000 | $0.00229 |
| Sonnet 5.5 | $0.00000 | $0.00114 |
| Haiku 4.5 | $0.00000 | $0.00057 |
Grade A, and why
middleware 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 1mo 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.

Express Middleware
Create Express middleware for $ARGUMENTS following project conventions.
Task
Create or optimize Express middleware based on the requirements:
- Analyze existing middleware: Check current middleware patterns, naming conventions, and file organization
- Examine Express setup: Review app configuration, middleware stack order, and TypeScript usage
- Identify middleware type: Determine the middleware category:
- Authentication/Authorization (JWT, sessions, role-based)
- Validation (request body, params, query validation)
- Logging (request/response logging, audit trails)
- Error handling (global error handlers, custom errors)
- Security (CORS, rate limiting, helmet)
- Utility (parsing, compression, static files)
- Check dependencies: Review existing middleware dependencies to avoid duplication
- Implement middleware: Create middleware with proper TypeScript types and error handling
- Test middleware: Write unit and integration tests following project patterns
- Update middleware stack: Integrate middleware into Express app configuration
- Add documentation: Include JSDoc comments and usage examples
Implementation Requirements
- Follow project's TypeScript conventions and interfaces
- Use existing error handling patterns and response formats
- Include proper request/response typing with custom interfaces
- Add comprehensive error handling and logging
- Consider middleware execution order and dependencies
- Implement proper async/await patterns for async middleware
- Follow project's folder structure for middleware files
Middleware Patterns to Consider
Based on the request:
- Authentication: JWT verification, session management, API key validation
- Authorization: Role-based access control, permission checking
- Validation: Schema validation with Joi/Zod, sanitization
- Logging: Request logging, performance monitoring, audit trails
- Error Handling: Global error handlers, custom error classes
- Security: CORS configuration, rate limiting, input sanitization
- Utility: Request parsing, response formatting, caching
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.

middleware is a command published in the GitHub repository Justdvp/claude-code-templates (7 stars, last pushed 6d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 572 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 2026-08-31.
