prompt-optimization skillA
prompt-optimization is agent-read markdown (skill) from fusengine/agents: Use when auditing an existing prompt for clarity, structure, or completeness issues, fixing vague instructions, or producing a before/after optimization report..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
<objective> Prompt Optimization analyzes and improves an existing prompt through a 5-step workflow: analyze the current prompt, identify issues, apply corrections, validate the improvement, and document the changes. Its checklist covers four dimensions -- clarity (unambiguous instructions, precise vocabulary), structure (well-delimited sections, logical order), completeness (output format, error cases, examples), and guardrails (explicit limits, forbidden behaviors, security). It never changes the prompt's original meaning, adds unrequested features, removes existing guardrails, or lengthens the prompt without justification. See `common-problems.md` for before/after fix patterns and `improvement-techniques.md` for strengthening via CoT, few-shot, or guardrails. </objective> # Prompt Optimization Skill for analyzing and improving existing prompts. ## References - [common-problems.md](references/common-problems.md) - Load when: diagnosing a vague or ambiguous prompt — 5 before/after examples (vague instructions, missing context, undefined format, no error handling, weak emphasis) …
