optimize-prompt

optimize-prompt is a command for Claude Code from vladolaru/claude-code-plugins. It costs 21 tokens per session (161 once invoked), scanned A, original, MIT.

A command for improving a prompt or instruction file with the prompt-engineer skill. It accepts a prompt, skill, agent definition, or related system instruction as its input.

In plain words
What is it for?
Use it to optimize skills, CLAUDE.md files, agent definitions, memory files, and other prompts.
Why use it?
It provides a repeatable way to make instructions clearer, resolve contradictions, and explain the purpose of each change. This can make agent behavior more predictable.

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-prompt 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 prompt-engineer skill to optimize the following:

$ARGUMENTS

If a file path is provided, read the file first and optimize its contents. Common targets:

  • Skills (SKILL.md files)
  • Agent definitions (agents/*.md)
  • CLAUDE.md or memory files
  • Any system prompt or instruction file

Apply ALL prompt engineering patterns from the skill's reference files. For EACH change, specify EXACTLY which technique(s) you used:

  • Pattern name (e.g., "Progressive Disclosure", "Emphasis Hierarchy")
  • Why this pattern applies here
  • Expected behavioral impact

CRITICAL: Changes without pattern attribution = task incomplete.

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.
