Tunes prompts iteratively using reflection and success metrics. Use for: optimize this prompt, dspy tune, improve prompt with reflection, `self-refine-loop`.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# DSPy Prompt Optimizer ## When to Use - User says **optimize this prompt** or task matches this capability - User says **dspy tune** or task matches this capability - User says **improve prompt with reflection** or task matches this capability ## Workflow 1. Capture baseline prompt and 2-3 example inputs with desired outputs. 2. Run baseline; score outputs against criteria. 3. Generate 3 prompt variants addressing failures. 4. Test variants; pick best by score. 5. Return optimized prompt with before/after metrics. ## Integrations - `self-refine-loop` - `auto-tester` - `hyper-skill-tester` ## Error Handling | Failure | Response | |---------|----------| | No examples | Ask for 2 input/output pairs minimum. | | Overfitting one example | Require 3+ diverse examples. | ## Gotchas - Keep prompt under 2000 tokens unless user needs longer. ## Example **Input:** User request matching triggers above. **Output:** Structured result per workflow with integrations invoked as needed.

How to install
mdr add stijnman/grok-custom-skills/dspy-prompt-optimizer@sha256:2d361b969d8ff9a9The line at the top of this page pins the label v1.2.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
