research-engineer

Provide the paper or link and state your constraints. The skill analyzes the method, writes a paper analysis and research plan, builds a minimal faithful implementation, runs smoke tests and experiments, and delivers an experiment report with reproducibility details.

It produces a research brief, continuous research notes, a source index, literature review, paper analysis, research and experiment plans, an implementation handoff, a loop log, an experiment report, and a decision log, plus an optional HTML explainer.

Yes. When the plan requires empirical validation, it handles environment setup, data preparation, training or fine-tuning runs, checkpoint tracking, metric evaluation, and debugging, recording commands, seeds, and raw output paths.

Yes. It respects user constraints on source gathering and can operate in supplied-source-only mode, recording access limits in the source index and justifying any gaps in source discovery.

Failed runs, unstable training, and mismatched reproduction results are preserved as research evidence in the loop log and experiment report, with interpretation, confounders, and a concrete next-loop decision rather than being discarded.

Use it when the task goes beyond reading and Q&A into implementation, reproduction, training, benchmarking, or empirical validation. For pure paper discovery and evidence-aware question answering, a narrower paper research assistant fits better.
