What is fullstack-template AGENTS.md?

Project instructions for a full-stack application with a Go backend, Next.js web app, PostgreSQL database, and Android app. They describe setup commands, layer-specific guidance, and development workflows.

They help set up the database and development servers, run the web and mobile projects, and follow the project’s test-driven development process.

They give contributors the repository’s expected tools, startup sequence, file-specific instructions, and testing rules before they change code.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00987	$0.00987
Opus 5.5	$0.00395	$0.00395
Sonnet 5.5	$0.00197	$0.00197
Haiku 4.5	$0.00099	$0.00099

Security

Grade A, and why

fullstack-template AGENTS.md 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.

How it starts

The opening of the file, as written. The whole thing — 106 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AGENTS.md

Fullstack project — Go + Gin backend, Next.js 16 + React 19 web app, PostgreSQL, Android mobile (Kotlin + Compose).

Each layer has its own AGENTS.md and docs/ folder. Read the file closest to what you are editing:

backend/AGENTS.md + backend/docs/ — Go API
web/AGENTS.md + web/docs/ — Next.js UI
mobile/AGENTS.md + mobile/docs/ — Android app

Claude Code users: see CLAUDE.md for the feature development workflow and subagent definitions.

Setup

Prerequisites: Go 1.21+, Node.js 20+, pnpm, Docker + Docker Compose, Android Studio Meerkat (2024.3+), JDK 17+, Android SDK API 36.

# 1. Database
cd backend && make docker-run

# 2. Backend API (hot reload, separate terminal)
cd backend && make watch        # → http://localhost:8080

# 3. Web app (separate terminal)
cd web && pnpm install && pnpm dev   # → http://localhost:3000

# 4. Mobile — open mobile/ in Android Studio and run on emulator/device
cd mobile && ./gradlew assembleDebug      # build only
cd mobile && ./gradlew installDebug       # build and install on connected device

Testing

TDD is required. Write failing tests first, then implement.

# Backend (Docker must be running)
cd backend && make test         # unit + integration
cd backend && make itest        # integration only

# Web
cd web && pnpm test             # Vitest unit + component tests
cd web && pnpm test:watch       # watch mode during development
cd web && pnpm lint
cd web && pnpm build

# Mobile
cd mobile && ./gradlew lint
cd mobile && ./gradlew test                  # unit tests (no device needed)
cd mobile && ./gradlew connectedAndroidTest  # instrumented tests (emulator/device required)

Backend DB and cache tests use Testcontainers (real PostgreSQL, real Redis). Never mock the database.
Web unit/component tests use Vitest + @testing-library/react. Server Component flows use Playwright (future).
Mobile Composable tests use Compose test rules in instrumented tests.

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.
