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.

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 | $0.00040 | $0.00430 |
| Opus 5.5 | $0.00016 | $0.00172 |
| Sonnet 5.5 | $0.00008 | $0.00086 |
| Haiku 4.5 | $0.00004 | $0.00043 |
Grade A, and why
ag-referencia-sdd 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.
What it actually says
Metodologia SDD (Spec Driven Development)
Principio 80/20: 80% planejamento, 20% execucao.
Fluxo Obrigatorio para Features/Refatoracoes
PRD.md → SPEC.md → Execucao → Review
- PRD: Problema, escopo, requisitos, metricas de sucesso
- SPEC: Plano tecnico (max 200 linhas, dividir se maior)
- Execucao: Implementar seguindo o SPEC exatamente
- Review: Validar contra criterios, documentar decisoes
Quando Usar SDD
| Cenario | SDD? |
|---|---|
| Nova feature | Sim |
| Bug fix complexo | Sim (simplificado) |
| Refatoracao | Sim |
| Hotfix urgente | Nao (documentar depois) |
| Quick task (< 30min) | Nao |

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.

ag-referencia-sdd is a skill published in the GitHub repository andregusman-raiz/a-gusman-claude (18 stars, last pushed 1mo ago), licensed MIT. It adds 40 tokens to every session and 430 once invoked, about $0.0002 per session on Opus 5.5. 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.
