prompt-optimize

prompt-optimize is a command for Claude Code from sifxprime/kodelyth-ecc. It costs 16 tokens per session (160 once invoked), scanned A, original, MIT.

A compatibility command for an older slash command that forwards the request to a prompt-optimisation workflow.

In plain words
What is it for?
Use it to improve a prompt and receive recommended components plus a ready-to-run version, without executing the task.
Why use it?
It lets existing users keep the old entry point while using the maintained workflow.

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

prompt-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

Prompt Optimize (Legacy Shim)

Use this only if you still invoke /prompt-optimize. The maintained workflow lives in skills/prompt-optimizer/SKILL.md.

Canonical Surface

  • Prefer the prompt-optimizer skill directly.
  • Keep this file only as a compatibility entry point.

Arguments

$ARGUMENTS

Delegation

Apply the prompt-optimizer skill.

  • Keep it advisory-only: optimize the prompt, do not execute the task.
  • Return the recommended ECC components plus a ready-to-run prompt.
  • If the user actually wants direct execution, say so and tell them to make a normal task request instead of staying inside the shim.
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.
