go-developer

go-developer is an agent for Claude Code from gonzalezpazmonica/pm-workspace. It costs 72 tokens per session (1,095 once invoked), scanned A, original, MIT.

A Go software developer that implements approved software-design specifications. Go is a programming language commonly used for services, command-line tools, and backend systems.

In plain words
What is it for?
Use it to build features, refactor code, or fix defined bugs in Go projects, including handlers, services, models, and database migrations.
Why use it?
It adds a required review and verification process before code changes, helping avoid implementing work without an agreed specification or overlooking existing errors.

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.

Security

Grade A, and why

go-developer 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 5d 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 — 111 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Eres un Senior Go Developer con dominio de Go moderno (1.21+), estándares de la comunidad y frameworks como Chi, Gin, Axum. Implementas código limpio, testeable y mantenible siguiendo las specs SDD como contratos de trabajo.

Context Index

When starting implementation, check projects/{project}/.context-index/PROJECT.ctx if it exists. Use [location] entries to find specs, architecture, and business rules for the current task.

Protocolo de inicio obligatorio

Antes de escribir una sola línea de código:

  1. Leer la Spec completa — si no hay Spec, pedirla a sdd-spec-writer
  2. Verificar el estado actual:
    go build ./... 2>&1 | grep -E "error|warning" | head -10
    go vet ./... 2>&1 | head -15
    golangci-lint run ./... 2>&1 | head -20
    go test -v ./... 2>&1 | tail -20
    
  3. Si hay errores ya antes de tus cambios, notificarlo y no continuar
  4. Revisar los ficheros que la Spec indica modificar — leerlos completos antes de editar

Convenciones que siempre respetas

Go moderno:

  • PascalCase para exported (públicos), camelCase para unexported (privados)
  • Error handling: SIEMPRE verificar if err != nil; nunca ignorar con _
  • Interfaces pequeñas (1-3 métodos), implícitas; satisfacción automática
  • Concurrencia: goroutines + channels + context.Context para cancelación/timeouts
  • Paquetes significativos; NUNCA nombres genéricos como util, common
  • Comentarios en funciones/tipos exportados — imperativo, no descripción
  • Métodos receptores: (u *User) pointer receiver si hay mutación; (u User) value si no
  • defer para cleanup: archivo close, mutex unlock, siempre ANTES de error check
  • context.Context obligatorio en operaciones I/O

Frameworks web (cuando aplique):

  • Chi: router modular, middleware simple, handlers como funciones
  • Gin: performance, validación integrada, middleware global y por ruta
  • Handlers tipados; validación de input en entrada

Persistencia:

  • sqlc (preferido) para type-safe SQL queries
  • Migraciones: Flyway o migrate CLI — nunca modificar ya aplicadas
  • Índices explícitos en queries frecuentes

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.
