Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 | $0.00112 | $0.02742 |
| Opus 5 | $0.00056 | $0.01371 |
| Sonnet 5 | $0.00022 | $0.00548 |
| Haiku 4.5 | $0.00011 | $0.00274 |
Grade A, and why
senior-backend 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 9d 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 — 368 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Engenheiro Backend Sênior
Padrões de desenvolvimento backend, design de API, otimização de banco de dados e práticas de segurança.
Início Rápido
# Gerar rotas de API a partir da spec OpenAPI
python scripts/api_scaffolder.py openapi.yaml --framework express --output src/routes/
# Analisar schema de banco de dados e gerar migrações
python scripts/database_migration_tool.py --connection postgres://localhost/mydb --analyze
# Teste de carga em um endpoint de API
python scripts/api_load_tester.py https://api.example.com/users --concurrency 50 --duration 30
Visão Geral das Ferramentas
1. API Scaffolder
Gera handlers de rotas de API, middleware e especificações OpenAPI a partir de definições de schema.
Entrada: Spec OpenAPI (YAML/JSON) ou schema de banco de dados Saída: Handlers de rota, middleware de validação, tipos TypeScript
Uso:
# Gerar rotas Express a partir da spec OpenAPI
python scripts/api_scaffolder.py openapi.yaml --framework express --output src/routes/
# Saída: Generated 12 route handlers, validation middleware, and TypeScript types
# Gerar a partir do schema do banco de dados
python scripts/api_scaffolder.py --from-db postgres://localhost/mydb --output src/routes/
# Gerar spec OpenAPI a partir de rotas existentes
python scripts/api_scaffolder.py src/routes/ --generate-spec --output openapi.yaml
Frameworks Suportados:
- Express.js (
--framework express) - Fastify (
--framework fastify) - Koa (
--framework koa)
2. Ferramenta de Migração de Banco de Dados
Analisa schemas de banco de dados, detecta mudanças e gera arquivos de migração com suporte a rollback.
Entrada: String de conexão do banco de dados ou arquivos de schema Saída: Arquivos de migração, relatório de diff de schema, sugestões de otimização
Uso:
# Analisar schema atual e sugerir otimizações
python scripts/database_migration_tool.py --connection postgres://localhost/mydb --analyze
# Saída: Missing indexes, N+1 query risks, and suggested migration files
# Gerar migração a partir do diff de schema
python scripts/database_migration_tool.py --connection postgres://localhost/mydb \
--compare schema/v2.sql --output migrations/
# Executar migração em modo dry-run
python scripts/database_migration_tool.py --connection postgres://localhost/mydb \
--migrate migrations/20240115_add_user_indexes.sql --dry-run
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.

senior-backend is a skill published in the GitHub repository ricneves-ai/flowgrammers-skills (112 stars, last pushed 3mo ago), licensed MIT. It adds 112 tokens to every session and 2,742 once invoked, about $0.0006 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 2026-09-03.
