optimize

A command for examining code and suggesting performance improvements. Performance means how quickly and efficiently software uses computing resources.

In plain words
What is it for?
Use it to review backend or frontend code, compare changes with benchmarks when possible, and prioritize improvements by likely impact and effort.
Why use it?
It helps find slow algorithms, inefficient database queries, excess memory use, unnecessary work, and avoidable network requests.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

optimize 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 2d 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

Optimize performance for: $ARGUMENTS

Analyze:

  1. Time complexity of algorithms
  2. Database query efficiency (N+1 problems, missing indexes)
  3. Memory usage patterns
  4. Bundle size impact (if frontend)
  5. Render performance and re-renders
  6. Caching opportunities
  7. Unnecessary computations
  8. Network request optimization

Provide before/after comparisons with benchmarks where possible. Prioritize optimizations by impact vs effort.

Changes

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.

optimize is a command published in the GitHub repository AgriciDaniel/claude-code-essentials-vs-code (57 stars, last pushed 4mo ago), licensed MIT. It adds 3 tokens to every session and 101 once invoked, about $0.0000 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 2026-08-30.
