performance-optimization

performance-optimization is a command for GitHub Copilot from saajunaid/caddis-plugin. It costs 17 tokens per session (961 once invoked), scanned A, original, MIT.

A command that improves code, database queries, or systems through profiling and structured analysis. Profiling measures where time or other resources are being used.

In plain words
What is it for?
It is for investigating and optimizing slow code, queries, or larger systems.
Why use it?
It provides a defined way to find performance problems before changing the implementation.

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-optimization 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 1mo 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.

Performance Optimization Prompt

Use this prompt when you need to optimize code for better performance.

Context Template

I need to optimize [FUNCTION/MODULE/QUERY] for better performance.

## Current Situation
- Current performance: [e.g., 5 seconds response time]
- Target performance: [e.g., < 500ms response time]
- Volume: [e.g., 10,000 records, 100 concurrent users]

## Constraints
- Cannot change: [e.g., database schema, external API]
- Must maintain: [e.g., existing API contract]
- Budget: [e.g., no additional infrastructure]

## What I've Tried
- [List previous optimization attempts]

## Code/Query to Optimize
[Paste the code or query]

Example: SQL Query Optimization

I need to optimize this SQL query for better performance.

## Current Situation
- Current performance: 12 seconds
- Target performance: < 1 second
- Volume: 500,000 records, queried 50 times/hour

## Constraints
- Cannot add new indexes (DBA approval required for production)
- Must return same result set

## What I've Tried
- Added WHERE clause filters
- Reduced SELECT columns

## Query to Optimize
SELECT c.customer_id, c.name, 
       COUNT(o.order_id) as order_count,
       SUM(o.total) as total_spent
FROM customers c
LEFT JOIN orders o ON c.customer_id = o.customer_id
WHERE o.created_at > '2024-01-01'
GROUP BY c.customer_id, c.name
ORDER BY total_spent DESC

Analysis Framework

When optimizing, ask for:

1. Profiling

  • Where is time being spent?
  • What are the bottlenecks?
  • Memory usage patterns?

2. Algorithm Analysis

  • Time complexity (O notation)?
  • Can we reduce iterations?
  • Are there more efficient algorithms?

3. Database Optimization

  • Query execution plan analysis
  • Index recommendations
  • Query restructuring

4. Caching Opportunities

  • What data is static or slowly changing?
  • What queries are repeated?
  • Where can we add memoization?

5. Parallelization

  • Can work be distributed?
  • Are there independent operations?
  • Would async help?

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-optimization is a command published in the GitHub repository saajunaid/caddis-plugin (0 stars, last pushed today), licensed MIT. It adds 17 tokens to every session and 961 once invoked, about $0.0001 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 2026-09-09.
