optimize

optimize is a command for Claude Code from rileyhilliard/agentrc. It costs 7 tokens per session (216 once invoked), scanned A, original, MIT.

A command that looks for performance problems in code and suggests ways to fix them. Performance problems are code choices that make an application slower or use more resources than necessary.

In plain words
What is it for?
Reviewing unstaged changes or a specified file or area, with issue locations, explanations, optimization examples, and prioritization by likely impact.
Why use it?
It gives a defined review process for finding costly code, explaining its impact, and weighing the likely benefit against the effort to change it.

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 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.

What it actually says

Use the Skill tool to invoke the optimizing-performance skill to analyze code for performance issues and suggest optimizations.

Arguments:

  • $ARGUMENTS: Optional file path or area to focus on (defaults to unstaged changes)

If $ARGUMENTS is empty:

  1. Run git diff to get unstaged changes
  2. Focus on optimizing the unstaged changes

If $ARGUMENTS is provided:

  • Use it as the focus area for optimization

When invoking the ce:optimizing-performance skill:

"Analyze code for performance issues and suggest optimizations.

Focus area: [unstaged changes from git diff OR $ARGUMENTS]

Provide:

  • Specific file:line references for each issue
  • Explanation of the performance impact
  • Code examples showing the optimization
  • Estimated improvement (if measurable)
  • Cost-benefit analysis for each proposed optimization

Prioritize high-impact optimizations over micro-optimizations."

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.
