From mechanist
Turn a refined research proposal or method idea into a detailed, claim-driven experiment roadmap. Use after `research-refine`, or when the user asks for a detailed experiment plan, ablation matrix, evaluation protocol, run order, compute budget, or paper-ready validation that supports the core problem, novelty, simplicity, and any LLM / VLM / Diffusion / RL-based contribution.

Use this skill after the method is stable enough that the next question becomes: what exact experiments should we run, in what order, to defend the paper? If the user wants the full chain in one request, prefer /research-refine-pipeline.
The goal is not to generate a giant benchmark wishlist. The goal is to turn a proposal into a claim -> evidence -> run order roadmap that supports four things:
refine-logs/ — Default destination for experiment planning artifacts.Read the most relevant existing files first if they exist:
refine-logs/FINAL_PROPOSAL.mdrefine-logs/REVIEW_SUMMARY.mdrefine-logs/REFINEMENT_REPORT.mdExtract:
If these files do not exist, derive the same information from the user's prompt.
Before proposing experiments, write down the claims that must be defended.
Use this structure:
Do not exceed MAX_PRIMARY_CLAIMS unless the paper truly has multiple inseparable claims.
Design the paper around a compact set of experiment blocks. Default to the following blocks and delete any that are not needed:
For each block, decide whether it belongs in:
Prefer one strong baseline family over many weak baselines. If a stronger modern baseline exists, use it instead of padding the list.
For every kept block, fully specify:
existing = an existing dataset used as-is, adapted = an existing dataset transformed/relabeled/filtered, constructed = built from scratch / synthetic), the source (dataset name, or construction method when constructed), the total available size of that source (available_n), and the planned amount this project will actually use (used_n). When used_n < available_n, state how/why it is subsetted. Budget-gate the subset: subset only when a scientific reason applies (a ladder-of-evidence screen, or the full set genuinely exceeds the declared GPU / compute budget) — do not subset merely to save cost when task.md declares a budget that covers the full available_n; in that case plan used_n = available_n at the user's named model size. A declared, generous budget is a mandate to run at fuller scale, not just an upper bound (see /auto-experiment GPU-budget rule).Special rules:
Build a realistic run order so the user knows what to do first.
Use this milestone structure:
For each milestone, estimate:
Separate must-run from nice-to-have experiments.

Keep the tracker compact and execution-oriented.

Follow these shared protocols for all output files:
- Output Versioning Protocol — write timestamped file first, then copy to fixed name
- Output Manifest Protocol — log every output to MANIFEST.md
- Output Language Protocol — respect the project's language setting
Large file handling: If the Write tool fails due to file size, immediately retry using Bash (cat << 'EOF' > file) to write in chunks. Do NOT ask the user for permission — just do it silently.
Every experiment must defend a claim. If it does not change a reviewer belief, cut it.
Prefer a compact paper story. Design the main table first, then add only the ablations that defend it.
Defend simplicity explicitly. If complexity is a concern, include a deletion study or a stronger-but-bloated variant comparison.
Defend frontier choices explicitly. If a modern primitive is central, prove why it is better than the strongest simpler alternative.
Prefer strong baselines over long baseline lists. A short, credible comparison set is better than a padded one.
Separate must-run from nice-to-have. Do not let appendix ideas delay the core paper evidence.
Reuse proposal constraints. Do not invent unrealistic budgets or data assumptions.
Do not fabricate results. Plan evidence; do not claim evidence.
/research-refine-pipeline -> one-shot method + experiment planning
/research-refine -> method and claim refinement
/experiment-plan -> detailed experiment roadmap
/run-experiment -> execute the runs
/auto-iteration-loop -> react to results and iterate on the paper
npx claudepluginhub zjunlp/mechanist --plugin mechanistRun an end-to-end workflow that chains `research-refine` and `experiment-plan`. Use when the user wants a one-shot pipeline from vague research direction to focused final proposal plus detailed experiment roadmap, or asks to build a pipeline, do it end-to-end, or generate both the method and experiment plan together.
Creates a detailed, reproducible research and experiment plan from a validated idea. Steps break goals, data, methods, ablation/sensitivity/robustness tests, significance checks, scheduling, risk, and cost estimates into actionable entries.
Designs experiment protocols, result tables, and evaluation plans before final metrics exist. Creates mock data for layout planning with clear boundaries against real results.
