Install with your agent
Agent handoff
Hand the extracted package to your coding agent with a concrete install brief instead of figuring it out manually.
- Download the package from Yavira.
- Extract it into a folder your agent can access.
- Paste one of the prompts below and point your agent at the extracted folder.
New install
I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Then review README.md for any prerequisites, environment setup, or post-install checks. Tell me what you changed and call out any manual steps you could not complete.
Upgrade existing
I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Then review README.md for any prerequisites, environment setup, or post-install checks. Summarize what changed and any follow-up checks I should run.

Service Layer Architecture
Clean, performant API layers with proper separation of concerns and parallel data fetching.
When to Use
Building REST APIs with complex data aggregation GraphQL resolvers needing data from multiple sources Any API where responses combine data from multiple queries Systems needing testable, maintainable code

Layer 1: Controllers (HTTP Only)
// controllers/Entity.ts import { getEntity, getEntities } from "../services/Entity"; const router = new Router(); router.get("/entity/:entityId", async (ctx) => { const { entityId } = ctx.params; if (!entityId) { ctx.status = 400; ctx.body = { error: "Invalid entity ID" }; return; } const entity = await getEntity(entityId); if (!entity) { ctx.status = 404; ctx.body = { error: "Entity not found" }; return; } ctx.status = 200; ctx.body = entity; });
Layer 2: Services (Business Logic)
// services/Entity.ts import { queries } from "@common"; export const getEntityData = async (entity: RawEntity): Promise<EnrichedEntity> => { // Parallel fetch all related data const [metadata, score, activity, location] = await Promise.all([ queries.getMetadata(), queries.getLatestScore(entity.id), queries.getActivity(entity.id), queries.getLocation(entity.slotId), ]); // Transform and combine return { ...entity, bonded: entity.bonded / Math.pow(10, metadata.decimals), total: score?.total ?? 0, location: location?.city, activity: { activeCount: activity?.active?.length ?? 0, inactiveCount: activity?.inactive?.length ?? 0, }, }; }; export const getEntity = async (entityId: string): Promise<EnrichedEntity | null> => { const entity = await queries.getEntityById(entityId); if (!entity) return null; return getEntityData(entity); }; export const getEntities = async (): Promise<EnrichedEntity[]> => { const all = await queries.allEntities(); const enriched = await Promise.all(all.map(getEntityData)); return enriched.sort((a, b) => b.total - a.total); };
Layer 3: Queries (Database Access)
// queries/Entities.ts import { EntityModel } from "../models"; export const allEntities = async () => { return EntityModel.find({}).lean(); // Always use .lean() }; export const getEntityById = async (id: string) => { return EntityModel.findOne({ id }).lean(); }; export const validEntities = async () => { return EntityModel.find({ valid: true }).lean(); };
Parallel Data Fetching
// BAD: Sequential (slow) const metadata = await queries.getMetadata(); const score = await queries.getScore(id); const location = await queries.getLocation(id); // Time: sum of all queries // GOOD: Parallel (fast) const [metadata, score, location] = await Promise.all([ queries.getMetadata(), queries.getScore(id), queries.getLocation(id), ]); // Time: max of all queries

NEVER Do
NEVER put database queries in controllers โ Violates separation NEVER put HTTP concerns in services โ Services must be reusable NEVER fetch related data sequentially โ Use Promise.all NEVER skip .lean() on read queries โ 5-10x faster NEVER expose raw database errors โ Transform to user-friendly messages
