reevo SKILL.md skillA
reevo from optima-cityu/llm4ad_next is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add optima-cityu/llm4ad_next/reevo@git:20260825.2005c66Pins git:20260825.2005c66 in mdr.lock. Pin the fingerprint instead.

Reflective Evolution (ReEvo) method skill. USE WHEN the user explicitly requests ReEvo / Reflective Evolution, or wants evolution with reflection mechanisms that summarize failure lessons and inject them into the next generation.
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
# Reflective Evolution (ReEvo) Skill > **Paper**: Ye et al., "ReEvo: Large Language Models as Hyper-Heuristics with Reflective Evolution", NeurIPS 2024. ## 1. Method Essence ReEvo adds a **reflection layer** to the evolution loop (sample → evaluate → select): before each generation, it summarizes success/failure patterns from historical samples and injects the reflection into the prompt, so the next mutation "stands on experience" rather than trying blindly. Reflection has two levels: - **Long-term reflection**: Overall summary of all historical individuals — "what structures work/fail, what patterns repeatedly fail" - **Short-term reflection**: Local review of the most recent N individuals (N=5) — "what changed last round, how did it perform" ## 2. Recommended Parameters See `params.yaml` in this directory for the recommended parameter configuration. **Parameter Guidance**: - `population_size`: 8-12 gives more material for reflection; start with 8. - `mutation_rate`: 0.5 is balanced; increase for more diversity, decrease for stability. - `max_sample_nums`: ReEvo is more sample-efficient than EoH; 100 is often sufficient. ### What Happens During Evolution …

How to install
mdr add optima-cityu/llm4ad_next/reevo@sha256:fc1438a6100547acThe line at the top of this page pins the label git:20260825.2005c66, 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.
