What is techagenda CLAUDE.md?

A set of instructions for Tech Agenda, an open-source technology-events aggregator. It explains the Go backend, server-rendered React interface, database migrations, code generation, testing, and checks.

Running the service, applying or creating database migrations, generating enums, testing Go packages, linting code, and building or checking documentation.

It gives coding agents the project's architecture and approved commands before they make changes. This helps avoid using the wrong development or verification process.

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	$0.01507	$0.01507
Opus 5	$0.00754	$0.00754
Sonnet 5	$0.00301	$0.00301
Haiku 4.5	$0.00151	$0.00151

Security

Grade A, and why

techagenda 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 8d 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.

Sobre o projeto

Tech Agenda é um agregador open source de eventos de tecnologia (DEV, DEVOPS, PRODUCT, DESIGN, MGMT). Backend em Go que serve uma UI React/TypeScript via SSR — não é uma SPA separada; o Go renderiza o React no servidor e devolve HTML.

Comandos

make run                      # sobe o serviço (go run main.go) — porta 8000 por padrão
make migrate-up               # roda migrations pendentes (goose)
make migrate-status           # status das migrations
make new-migration migration=nome_da_migration   # cria nova migration .go em ./migrations
make key-gen                  # gera par de chaves ED25519 para o JWT
make install-deps             # instala goose e go-enum (necessário para gerar enums)

go test ./...                 # roda todos os testes
go test ./pkg/event/...       # roda testes de um pacote
go test -run TestNome ./pkg/event/   # roda um único teste

golangci-lint run             # lint (CI usa golangci-lint v2)
go generate ./...             # regenera enums (go-enum) a partir das diretivas //go:generate

Postgres local: docker-compose up -d postgres (sobe na 5432, auth trust). Config vem de variáveis de ambiente — veja env.example. O Makefile carrega .env.local se existir, senão env.example.

Dependências de UI: cd ui && npm install (ou yarn). O go-react-ssr cuida do bundling em runtime; não há build separado de frontend em dev.

Arquitetura

Injeção de dependência com Uber fx. main.go → cmd.Execute() (cobra) → rootCmd monta o grafo fx em cmd/root.go, registrando cada módulo de pkg/. Cada feature em pkg/<feature>/ expõe um fx.go com Module() que faz fx.Provide(...) dos services/handlers e fx.Invoke(Router) para registrar rotas no Echo. Para adicionar uma feature nova: crie o módulo e registre-o na lista em cmd/root.go.

Camadas dentro de um pacote (padrão em pkg/event):

model.go — struct GORM + DTOs; embeda lib/model.Model
service.go — interface Service + implementação com *gorm.DB
router.go — registra rotas no *echo.Echo
fx.go — Module() que amarra tudo
*_enum.go / model_enum.go — gerado por go-enum

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.
