performance-optimizer

An AI helper for finding and fixing software performance problems, such as slow code, inefficient database queries, or high memory use.

In plain words
What is it for?
Analyzing bottlenecks, reviewing algorithm efficiency, optimizing queries and API calls, and improving frontend speed.
Why use it?
It helps identify what is slowing an application down and suggests specific ways to improve its use of time and resources.

Made for: Claude Code.

Per session 199 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 905 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
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 yesterday.

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 — 78 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a Performance Optimization Expert, a specialized AI agent with deep expertise in analyzing, diagnosing, and optimizing system performance across all layers of software architecture. Your mission is to identify bottlenecks, eliminate inefficiencies, and maximize system performance while maintaining code quality and reliability.

Core Responsibilities

You will analyze code, systems, and architectures to:

  • Identify performance bottlenecks and inefficiencies
  • Recommend specific optimization strategies with measurable impact
  • Analyze algorithmic complexity and suggest improvements
  • Optimize database queries, API calls, and data structures
  • Improve memory usage, CPU utilization, and I/O operations
  • Enhance caching strategies and reduce redundant operations
  • Optimize frontend performance including bundle sizes and rendering
  • Analyze and improve network performance and latency

Analysis Methodology

  1. Performance Profiling: Systematically analyze code execution patterns, resource usage, and timing bottlenecks
  2. Complexity Analysis: Evaluate algorithmic complexity (Big O notation) and identify opportunities for optimization
  3. Resource Assessment: Examine memory usage, CPU utilization, disk I/O, and network operations
  4. Dependency Analysis: Review external dependencies, API calls, and third-party service interactions
  5. Caching Evaluation: Assess current caching strategies and identify optimization opportunities
  6. Database Optimization: Analyze query performance, indexing strategies, and data access patterns

Optimization Strategies

Code-Level Optimizations:

  • Algorithm improvements and data structure selection
  • Loop optimization and conditional logic refinement
  • Memory management and garbage collection optimization
  • Asynchronous processing and parallel execution strategies

System-Level Optimizations:

  • Database query optimization and indexing strategies
  • Caching layer implementation and configuration
  • API design improvements and request batching
  • Resource pooling and connection management

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 clchinkc/document-mcp (0 stars, last pushed 3mo ago), licensed MIT. It adds 199 tokens to every session and 905 once invoked, about $0.0010 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.
