What is fullstack-template CLAUDE.md?

A repository guide for a full-stack application using Next.js and React in the web interface, Go in the backend, PostgreSQL for data, and Kotlin for Android. It records the commands and workflows for running, testing, and building each part.

It is for developing and testing web, backend, database, and Android features in one repository.

It gives a coding agent the project's technology choices and required commands before it changes 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	$0.02671	$0.02671
Opus 5.5	$0.01068	$0.01068
Sonnet 5.5	$0.00534	$0.00534
Haiku 4.5	$0.00267	$0.00267

Security

Grade A, and why

fullstack-template CLAUDE.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.

Project Guide

Stack

Layer	Tech
Frontend	Next.js 16, React 19, TypeScript 5, Tailwind CSS 4
Backend	Go 1.25, Gin, `database/sql` + pgx v5 stdlib
Database	PostgreSQL 16 via Docker Compose
Mobile	Android, Kotlin 2.2, Jetpack Compose BOM 2026.02, Material3
Dev tools	pnpm, Air (Go hot reload), Testcontainers, Gradle 9.4

Run commands

cd backend && make docker-run   # start Postgres
cd backend && make watch        # backend dev with hot reload (Air) → :8080
cd web && pnpm dev              # web dev → :3000

cd backend && make test         # all tests
cd backend && make itest        # integration tests only (requires Docker)
cd web && pnpm lint && pnpm build
cd web && pnpm test             # Vitest unit + component tests
cd web && pnpm test:watch       # watch mode during TDD

cd mobile && ./gradlew assembleDebug          # build Android APK
cd mobile && ./gradlew lint && ./gradlew test # mobile quality gate
cd mobile && ./gradlew connectedAndroidTest   # instrumented tests (emulator/device required)

Migration commands (run from backend/)

make migrate-create name=<slug>   # create a new timestamped SQL migration file
make migrate-status               # show applied vs. pending migrations
make migrate-up                   # apply all pending migrations
make migrate-up-one               # apply the next pending migration only
make migrate-down                 # roll back the last applied migration
make migrate-reset                # roll back everything to version 0
make migrate-version              # print current schema version

Feature development workflow — always follow this

Check docs first — delegate to docs agent: find relevant topic docs, verify they match the current code
Fix stale docs — if docs diverge from code, update docs before implementing
Migrate — if the feature needs new or changed tables: make migrate-create name=<slug>, write the SQL, make migrate-up
Write tests first (TDD) — write failing tests that describe the intended behaviour before writing any implementation code
Implement — delegate to backend or web agent, passing the relevant doc content as context; implementation is complete when all tests pass
Env vars — if any new env vars were added to loadConfig(), add them to backend/.env.example with a safe placeholder value and a comment explaining the format
Update docs — delegate to docs agent: update last_verified, add new topics if introduced
Quality gate — run /project:check before declaring done

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.
