What it does

Elysia API Routes is an agent skill from biersoeckli/QuickStack. Create and update QuickStack Elysia REST API routes using the project's established /api/v1 route conventions. Use when adding or editing files under src/server/api/v1, defining Elysia query/params/body/response schemas, or handling REST API authorization and errors.

Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Backend & APIs, covering REST APIs and Authorization and RBAC. The repository describes itself as: Open-source, self-hostable alternative to Vercel, Netlify, Railway and Heroku. Self-host any app on your own servers in minutes. The licence is GPL-3.0.

When your agent uses it

Example prompts

“/elysia-api-routes”

What it can do on your machine

Read from SKILL.md and the folder at commit 32bca57. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
- yarn
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use yarn, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Elysia API Routes loads about 1.1k tokens when it runs. Until then it costs about 71 tokens; SKILL.md has 307 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~71
When it runs · the whole SKILL.md, loaded when a task matches: ~1.1k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Elysia API Routes

Quick Start

For QuickStack REST routes under src/server/api/v1, follow the current examples in app/route.ts and project/route.ts:

export const resourceRoutes = new Elysia()
    .derive(ApiUtils.deriveFunc)
    .get('/resources/:id', async ({ params, identity }) => {
        if (!identity) throw new ApiUnauthorizedException()

        const resource = await resourceService.getByIdOrUndefined(params.id);
        if (!resource) throw new ApiNotFoundException();

        ensureReadResource(identity, resource.id);

        return resource;
    }, {
        params: z.object({
            id: z.string(),
        }),
        response: ApiUtils.mapResponseModel(ResourceModel),
        detail: { summary: 'Get resource by id', security: [{ bearerAuth: [] }] }
    });

Required Route Shape

Start each route module with new Elysia().derive(ApiUtils.deriveFunc) so handlers receive identity.
Import ApiUtils from src/server/utils/api-response.utils.
Import ApiUnauthorizedException, ApiNotFoundException, and ServiceException from src/shared/model/service.exception.model as needed.
Declare query, params, and body directly in route options with Zod schemas.
Declare response with ApiUtils.mapResponseModel(successSchema).
Keep OpenAPI metadata in detail, with a short summary and security: [{ bearerAuth: [] }] for protected routes.

Handler Rules

If identity is missing, throw new ApiUnauthorizedException().
If a requested resource does not exist, throw new ApiNotFoundException().
Use shared authorization helpers such as ensureReadApp, ensureWriteApp, ensureCreateAppInProject, ensureDeleteAppInProject, ensureReadProject, and ensureAdmin.
Let shared authorization helpers throw; do not duplicate permission checks inline except for simple admin/read filtering already established in list routes.
Throw ServiceException for expected domain validation errors, such as immutable projectId violations.
Return success payloads directly; do not wrap them in { data }, { status }, or error envelopes.
Do not return ApiUtils.problem(...), raw Response, or Elysia status(...) for expected route errors.

Schema Rules

Use inline Zod objects for simple route params and query inputs.
Use existing write schemas, such as AppExtendedWriteZodModel or a local projectWriteSchema, for bodies.
Do not parse query, params, or body inside the handler if the route option already declares the schema.
Do not use nested schema: { query, params, body } in these route modules.
For delete routes, return undefined and declare response: ApiUtils.mapResponseModel(z.undefined()).
For deployment request routes, return { deploymentId } and declare response: ApiUtils.mapResponseModel(z.object({ deploymentId: z.string() })).

Write Route Pattern

Use POST upsert semantics:

.post('/projects', async ({ body, identity }) => {
    if (!identity) throw new ApiUnauthorizedException()

    ensureAdmin(identity);

    let existing: Project | null = null;
    if (body.id) {
        existing = await projectService.getByIdOrUndefined(body.id);
        if (!existing) throw new ApiNotFoundException();
    }

    return projectService.save({ id: existing?.id, name: body.name });
}, {
    body: projectWriteSchema,
    response: ApiUtils.mapResponseModel(ProjectModel),
    detail: { summary: 'Create or update project', security: [{ bearerAuth: [] }] }
})

Validation Checklist

Run yarn tsc --noEmit after route changes.
Check that every accepted input has a route-level Zod schema.
Check that every route has response: ApiUtils.mapResponseModel(...).
Check that expected failures are thrown as exceptions; route mounting maps them centrally with ApiUtils.mapError(...).
Check CONTEXT.md for REST API domain terms and write semantics before changing behavior.
