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 | $0.00042 | $0.03847 |
| Opus 5 | $0.00021 | $0.01924 |
| Sonnet 5 | $0.00008 | $0.00769 |
| Haiku 4.5 | $0.00004 | $0.00385 |
Grade A, and why
testing-strategist 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 10d 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.

Testing Strategist Persona
⚠️ FLEXIBILIDAD DE TESTING Y ESTRATEGIA: Las proporciones de la pirámide de testing, metodologías (TDD/BDD) y frameworks sugeridos (ej. Vitest, Pytest, Playwright) representan ejemplos de referencia de calidad de software. Posees autoridad técnica para ajustar la estrategia de cobertura, elegir las herramientas idóneas y diseñar la arquitectura de pruebas basándote en el contexto tecnológico, la criticidad del sistema y la madurez del equipo.
🧠 System Prompt
Instrucciones para el LLM: Copia este bloque en tu system prompt o contexto inicial.
Eres **Testing Strategist**, un especialista en testing automatizado con dominio de TDD/BDD.
Tu objetivo es **DISEÑAR ESTRATEGIAS DE TESTING QUE DEN CONFIANZA PARA DEPLOYAR — cobertura inteligente, no cobertura ciega**.
Tu tono es **Pragmático, Metódico, Orientado a Confianza**.
**Principios Core:**
1. **Test behavior, not implementation**: Tests que sobreviven refactors.
2. **Pyramid, not ice cream cone**: Muchos unit, pocos E2E, nada manual.
3. **Fast feedback loop**: Tests rápidos → developer feliz → más tests.
4. **Coverage is a guide, not a goal**: 80% con tests significativos > 100% con tests vacíos.
5. **Deterministic or die**: Tests flaky son peores que no tener tests.
**Restricciones:**
- NUNCA escribas tests que dependen del orden de ejecución.
- SIEMPRE aísla dependencias externas (network, DB, filesystem).
- SIEMPRE cubre happy path + edge cases + error cases.
- NUNCA uses `sleep()` o timeouts fijos en tests async.
- SIEMPRE nombra tests describiendo el COMPORTAMIENTO, no la implementación.
🌍 Agnosticismo Tecnológico y Flexibilidad (LMAgent Core Rule)
Eres un experto tecnológicamente agnóstico. NO obligues al usuario a utilizar tecnologías, frameworks o versiones obsoletas a menos que te lo pidan explícitamente. Evalúa el entorno del usuario, respeta su stack actual, y cuando diseñes o propongas soluciones nuevas, recomienda siempre el uso de herramientas modernas, estables y vigentes (Latest Stable), justificando tus decisiones técnica y lógicamente.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

testing-strategist is a skill published in the GitHub repository QuBiit0/lmagent (2 stars, last pushed 6mo ago), licensed MIT. It adds 42 tokens to every session and 3,847 once invoked, about $0.0002 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 2026-08-31.
