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 | $0.00000 | $0.00517 |
| Opus 5 | $0.00000 | $0.00259 |
| Sonnet 5 | $0.00000 | $0.00103 |
| Haiku 4.5 | $0.00000 | $0.00052 |
Grade A, and why
trpc 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 4d 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 — 60 lines — stays where its author put it; the contents beside it link to each section on GitHub.
tRPC Skill
End-to-end typesafe APIs made easy.

trpc -- "works well with" --> react
Quick Start
tRPC allows you to easily build & consume fully typesafe APIs without schemas or code generation. It relies on TypeScript inference to share types between your server and client.
npm install @trpc/server @trpc/client @trpc/react-query @tanstack/react-query zod
Production Patterns
Input Validation
tRPC strongly integrates with Zod. Always define an .input(z.object({...})) schema for your mutations. tRPC will automatically reject invalid payloads before your resolver function ever executes.
Architecture & Scaling
Routers and Procedures
Group your endpoints into sub-routers (e.g., userRouter, postRouter) and merge them into an appRouter. This prevents your primary router file from becoming unmaintainable.
Error Recovery
Throw TRPCError with specific codes (e.g., UNAUTHORIZED, NOT_FOUND). On the client, React Query will automatically catch these and expose them via the error object.
Security Notes
Implement a protectedProcedure middleware. Extract the session from the context (ctx), verify it, and throw a TRPCError if invalid. Use this procedure for all secure endpoints instead of the standard publicProcedure.
Relationships
Works Well With: nextjs, react

Why use this skill
Use this when your agent works with trpc — structured patterns beat pasted docs and prevent common hallucinations.
AI pitfalls
- Referencing CLI flags or config keys that do not exist
- Using outdated major versions of tools
- Skipping lockfile or version pinning in examples
Production checklist
- Secrets in environment variables, not source code
- Error handling and logging in place
- Rate limits and timeouts configured
What ships with it
3 files 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.

trpc is a skill published in the GitHub repository ashish7802/awesome-api-skills (13 stars, last pushed 7d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 517 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 2026-09-03.

client-setup
Create a vanilla tRPC client with createTRPCClient (), configure link chain with httpBatchLink/httpLink, dynamic headers for auth, transformer on links (not client constructor). Infer types with inferRouterInputs and inferRouterOutputs. AbortController signal support. TRPCClientError typing.
adapter-express
Mount tRPC as Express middleware with createExpressMiddleware() from @trpc/server/adapters/express. Access Express req/res in createContext via CreateExpressContextOptions. Mount at a path prefix like app.use('/trpc', ...). Avoid global express.json() conflicting with tRPC body parsing for FormData.
