pm-sonnet-opus-haiku

pm-sonnet-opus-haiku is a skill for Claude Code, Codex from MauricioPerera/KDD. It costs 277 tokens per session (6,841 once invoked), scanned A, original, MIT.

A development workflow that assigns planning, implementation, and quality-checking work to different Claude models. It uses a project manager, an implementer, and a QA reviewer.

In plain words
What is it for?
Planning work, writing specifications and tests, delegating implementation, checking results, and integrating changes across one or more repository tasks.
Why use it?
It separates planning from production coding and review, making responsibilities and checks explicit across a development task.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

    Skill instructs the agent to omit warnings, disclaimers, or ethical commentary. Stripping safety caveats hides risk from the user and is a common jailbreak preamble.
    Fix: Remove instructions that suppress warnings, disclaimers, or ethical commentary. Let the agent surface safety-relevant caveats to the user.

Token cost

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.

Security

Grade A, and why

pm-sonnet-opus-haiku 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 12d 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 — 186 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Sonnet 5 = PM · Opus 4.8 = implementador · Haiku 4.5 = QA

Patrón genérico, independiente del repo. El repo de trabajo es el cwd salvo que el usuario indique otro: sustituí <REPO> por esa ruta. Sirve para una sola tarea o para orquestar varias en paralelo.

Por qué esta asignación (no la inviertas)

  • El orquestador quema turnos y contexto durante TODA la sesión; el implementador solo por tarea acotada. Por eso el barato dirige y el caro implementa: Sonnet 5 rinde cerca de Opus 4.8 en trabajo agéntico a fracción del precio, y trae 1M de contexto por defecto, que es exactamente lo que un PM necesita para sostener plan, specs y veredictos sin compactar.
  • Opus 4.8 se reserva para donde su capacidad extra rinde: implementación no trivial, arquitectura, bugs finos.
  • QA en Haiku 4.5, misma familia que el implementador: se pierde la diversificación de sesgos entre proveedores que daba un modelo externo, a cambio de cero dependencia externa (sin login, sin cuenta cloud, sin tags que se retiran) y de read-only GARANTIZADO por ausencia de tools de escritura en la definición del subagent — no por una bandera de permisos que hay que confiar a ciegas. Si más adelante querés diversidad real de familia, se puede volver a un QA externo (Kimi, GPT, etc.) sin tocar el resto del patrón.

Prerrequisitos

  • Sesión principal en Sonnet 5: arrancá con claude --model claude-sonnet-5 o cambiá con /model claude-sonnet-5. Confirmalo antes de empezar; si la sesión corre en otro modelo, avisale al usuario.
  • Subagent implementador definido en .claude/agents/implementador-opus.md (plantilla abajo). Si no existe, crealo como primer paso.
  • Subagent QA definido en .claude/agents/qa-haiku.md (plantilla abajo). Si no existe, crealo como primer paso, junto con el implementador.
  • Subagent verificador adversarial definido en .claude/agents/verificador-adversarial-haiku.md (plantilla abajo). Solo hace falta si vas a usar el paso opcional de verificación adversarial (Capa 3); crealo la primera vez que lo necesites.

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.
