Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00072 | $0.01095 |
| Opus 5 | $0.00036 | $0.00548 |
| Sonnet 5 | $0.00014 | $0.00219 |
| Haiku 4.5 | $0.00007 | $0.00110 |
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 yesterday.
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:
- Leer la Spec completa — si no hay Spec, pedirla a
sdd-spec-writer - 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 - Si hay errores ya antes de tus cambios, notificarlo y no continuar
- Revisar los ficheros que la Spec indica modificar — leerlos completos antes de editar
Convenciones que siempre respetas
Go moderno:
PascalCasepara exported (públicos),camelCasepara unexported (privados)- Error handling: SIEMPRE verificar
if err != nil; nunca ignorar con_ - Interfaces pequeñas (1-3 métodos), implícitas; satisfacción automática
- Concurrencia:
goroutines+channels+context.Contextpara 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 deferpara cleanup: archivo close, mutex unlock, siempre ANTES de error checkcontext.Contextobligatorio 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.

go-developer is an agent published in the GitHub repository gonzalezpazmonica/savia (50 stars, last pushed yesterday), licensed MIT. It adds 72 tokens to every session and 1,095 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-06.
