triad-endpoint

triad-endpoint is a skill for Claude Code from justhamade/triadjs. It costs 74 tokens per session (2,612 once invoked), scanned A, original, MIT.

A TriadJS feature for declaring HTTP endpoints, the server routes that receive requests and return responses, from one definition containing methods, paths, data rules, handlers, and status codes.

In plain words
What is it for?
Building routers and REST-style APIs, defining request bodies, parameters, queries, and responses, requiring authentication, and writing handlers that use typed state and services.
Why use it?
It keeps request validation, response shapes, authentication hooks, and generated API documentation aligned in one place.

Token cost

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.

Security

Grade A, and why

triad-endpoint 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 6d 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.

Endpoints and routers

endpoint() signature

import { endpoint, scenario, t } from '@triadjs/core';

export const createPet = endpoint({
  name: 'createPet',            // operationId in OpenAPI — must be unique
  method: 'POST',               // 'GET' | 'POST' | 'PUT' | 'PATCH' | 'DELETE'
  path: '/pets',                // Express-style (/pets/:id)
  summary: 'Create a new pet',  // one-line human summary
  description: 'Longer prose.', // optional, flows into OpenAPI
  tags: ['Pets'],               // used to group operations in OpenAPI
  request: {
    body: CreatePet,
    params: { id: t.string() },
    query: { limit: t.int32().default(20) },
    // headers: { xRequestId: t.string().optional() },
  },
  beforeHandler: requireAuth,   // optional — see §Auth below
  responses: {
    201: { schema: Pet,      description: 'Created' },
    401: { schema: ApiError, description: 'Missing or invalid token' },
    409: { schema: ApiError, description: 'Duplicate' },
  },
  handler: async (ctx) => {
    const pet = await ctx.services.petRepo.create({
      ownerId: ctx.state.user.id,  // typed state from beforeHandler
      ...ctx.body,
    });
    return ctx.respond[201](pet);
  },
  behaviors: [ /* scenarios — see triad-behaviors skill */ ],
});

Return value is a normalized Endpoint — pass it to router.add(...).

HandlerContext — what ctx contains

Everything on ctx is inferred from the request and responses declarations:

Field Type
ctx.params Inferred from request.params (or {})
ctx.query Inferred from request.query
ctx.body Inferred from request.body (or undefined)
ctx.headers Inferred from request.headers
ctx.services ServiceContainer (module-augment it — see triad-services skill)
ctx.state Readonly<TBeforeState> — state produced by the endpoint's beforeHandler. {} when no hook is declared
ctx.respond { [status]: (data) => HandlerResponse } — only declared statuses are present

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.
