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.

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 | $0.00021 | $0.02136 |
| Opus 5 | $0.00010 | $0.01068 |
| Sonnet 5 | $0.00004 | $0.00427 |
| Haiku 4.5 | $0.00002 | $0.00214 |
Grade A, and why
stress-test 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 13d 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 — 205 lines — stays where its author put it; the contents beside it link to each section on GitHub.
/em:stress-test — Teste de Estresse de Premissas de Negócio
Comando: /em:stress-test <assumption>
Pegue qualquer premissa de negócio e quebre-a antes que o mercado o faça. Projeções de receita. Tamanho de mercado. Fosso competitivo. Velocidade de contratação. Retenção de clientes.
Por que a Maioria das Premissas Está Errada
Fundadores são otimistas por natureza. Isso é uma característica — você precisa de otimismo para começar algo do zero. Mas se torna uma desvantagem quando as premissas nos modelos de negócio são infladas pelo mesmo otimismo que o fez começar.
As premissas mais perigosas são aquelas com as quais todos concordam.
Quando o time inteiro acredita que o mercado de R$250M é real, quando cada conversa com investidor vai bem então você assume que a rodada fechará, quando seu modelo mostra R$10M ARR em dezembro e ninguém questiona — é quando você está mais exposto.
Teste de estresse não é pessimismo. É calibração.
A Metodologia de Teste de Estresse
Passo 1: Isole a Premissa
Declare explicitamente. Não "nosso mercado é grande" mas "o mercado total endereçável para software de gestão de despesas B2B para PMEs brasileiras é R$11,5B."
Quanto mais específica a premissa, mais testável ela é. Premissas vagas são infalsificáveis — e portanto inúteis.
Tipos comuns de premissas:
- Tamanho de mercado — TAM, SAM, SOM; taxa de crescimento; segmentos de clientes
- Comportamento do cliente — disposição para pagar, churn, expansão, indicações
- Modelo de receita — taxas de conversão, tamanho do negócio, ciclo de vendas, CAC
- Posição competitiva — durabilidade do fosso, velocidade de resposta do concorrente, custo de troca
- Execução — velocidade do time, cronograma de contratação, cronograma de produto, escalabilidade operacional
- Macro — ambiente regulatório, condições econômicas, disponibilidade de tecnologia
Passo 2: Encontre as Evidências Contrárias
Para cada premissa, busque ativamente evidências de que está errada.
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.

stress-test is a skill published in the GitHub repository ricneves-ai/flowgrammers-skills (112 stars, last pushed 3mo ago), licensed MIT. It adds 21 tokens to every session and 2,136 once invoked, about $0.0001 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 2026-08-30.
