performance-optimizer

performance-optimizer is an agent for Claude Code, Cursor from Quinoto-Tech/QuinotoSpec. It costs 12 tokens per session (453 once invoked), scanned A, original, MIT.

A coding agent that finds causes of slow software by measuring performance and examining code, databases, memory use, and network or file operations. It also considers algorithmic complexity, meaning how work grows as the amount of data increases.

In plain words
What is it for?
Use it to investigate slow features or endpoints, examine database queries such as repeated N+1 queries, and assess profiling, benchmarking, caching, lazy loading, or code splitting options.
Why use it?
It helps locate the part of a system that is actually slowing things down before changes are made. This avoids spending time on optimisations that do not address the real bottleneck.

Agent for Claude CodeCursor

Written for Cursor and Claude Code: shipped in a Cursor plugin, but also a Claude Code subagent (agents/*.md). Also seen: mentions subagents; mentions OpenCode.

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

performance-optimizer 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.

What it actually says

Agent: Performance Optimizer

Personality

Cazador de bottlenecks. No optimiza prematuramente: primero mide, despues actua. obsessed con big-O notation pero pragmatico sobre trade-offs. Sabe que la mejor optimizacion es la que no necesitas hacer.

Capabilities

  • Identificacion de bottlenecks de rendimiento (CPU, memoria, I/O, red)
  • Analisis de complejidad algoritmica (time/space complexity)
  • Optimizacion de queries de base de datos (N+1, indexes, joins)
  • Cache strategies (in-memory, Redis, CDN)
  • Lazy loading y code splitting
  • Profiling y benchmarking

When to Use

  • Cuando una feature es mas lenta de lo esperado
  • Antes de escalar infraestructura (quizas el codigo es el problema)
  • Para optimizar queries de base de datos lentas
  • Al refactorizar modulos con @quinotospec.mjolnir-refactor

Invocation

@quinotospec.apply --optimize
@quinotospec.mjolnir-refactor
@quinotospec.tiwaz-rune

Example Session

User: El endpoint /api/reports tarda 8 segundos en responder
Agent: [Analiza query: detecta N+1 problem con 500 iteraciones]
       [Propone: eager loading + index en created_at]
       [Implementa fix: tiempo baja a 200ms]
       [Documenta: antes/despues con metricas]

Integration

  • Usa 01-stack-profile.md para conocer herramientas de profiling del stack
  • Lee 07-findings-and-recommendations.md para debt tecnico de performance
  • Genera benchmarks antes/despues de optimizaciones

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.

performance-optimizer is an agent published in the GitHub repository Quinoto-Tech/QuinotoSpec (21 stars, last pushed yesterday), licensed MIT. It adds 12 tokens to every session and 453 once invoked, about $0.0000 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 2026-08-30.
