## What it does

The skill kicks in once your main results pass the claim check and you still need ablations for submission. It first gathers context from project files: the method and its components, current experiment metrics, the claims you intend to make, and the compute you have available.

Codex leads the design through the `mcp__codex__codex` MCP server, acting as a strict reviewer. You get a table of ablations with `what_it_tests` and `expected_if_component_matters` for each, a coverage assessment of reviewer questions, a list of experiments that would add no insight, a run order, and a GPU-hour estimate. Claude then checks the budget, which ablations need code changes versus config-only edits, and what can run in parallel. Results go into `EXPERIMENT_LOG.md`.

Config-only ablations run before anything requiring code changes. If the total compute exceeds your budget, the skill proposes cuts and asks Codex to re-prioritize instead of dropping experiments silently. Component ablations outrank hyperparameter sweeps, and no ablation is generated for components identical to the baseline.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add wanshuiyin/Auto-claude-code-research-in-sleep --skill ablation-planner -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/ablation-planner/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/ablation-planner/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add wanshuiyin/Auto-claude-code-research-in-sleep --skill ablation-planner -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/ablation-planner/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add wanshuiyin/Auto-claude-code-research-in-sleep --skill ablation-planner -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/ablation-planner/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install wanshuiyin/Auto-claude-code-research-in-sleep ablation-planner
```

2. **Manually: put the files in place**
- File: `.github/skills/ablation-planner/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add wanshuiyin/Auto-claude-code-research-in-sleep --skill ablation-planner -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/wanshuiyin/Auto-claude-code-research-in-sleep --path skills/ablation-planner
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/ablation-planner/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add wanshuiyin/Auto-claude-code-research-in-sleep --skill ablation-planner -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/wanshuiyin/Auto-claude-code-research-in-sleep/tree/HEAD/skills/ablation-planner/SKILL.md

## When to use it
- plan ablations that answer reviewer questions
- isolate the contribution of each new component
- test sensitivity to key hyperparameters
- fit the ablation plan into an available GPU budget
- record negative results from experiments

## Example prompts
- plan ablations for my method, main results already pass result-to-claim
- /ablation-planner remove module X and replace Y with Z
- check whether this ablation plan fits our available GPUs

# Ablation Planner

Systematically design ablation studies that answer the questions reviewers will ask. Codex leads the design (reviewer perspective), CC reviews feasibility and implements.

## Context: $ARGUMENTS

## When to Use

- Main results pass `/result-to-claim` with claim_supported = yes or partial
- User explicitly requests ablation planning
- `/auto-review-loop` reviewer identifies missing ablations

## Workflow

### Step 1: Prepare Context

CC reads available project files to build the full picture:
- Method description and components (from `idea-stage/docs/research_contract.md`, legacy `docs/research_contract.md`, or project CLAUDE.md)
- Current experiment results (from EXPERIMENT_LOG.md, EXPERIMENT_TRACKER.md, or W&B)
- Confirmed and intended claims (from result-to-claim output or project notes)
- Available compute resources (from CLAUDE.md server config, if present)

### Step 2: Codex Designs Ablations

```
mcp__codex__codex:
  model: gpt-6-astra
  config: {"model_reasoning_effort": "xhigh"}
  prompt: |
    You are a rigorous ML reviewer planning ablation studies.
    Given this method and results, design ablations that:

    1. Isolate the contribution of each novel component
    2. Answer questions reviewers will definitely ask
    3. Test sensitivity to key hyperparameters
    4. Compare against natural alternative design choices

    Method: [description from project files]
    Components: [list of removable/replaceable components]
    Current results: [key metrics from experiments]
    Claims: [what we claim and current evidence]

    For each ablation, specify:
    - name: what to change (e.g., "remove module X", "replace Y with Z")
    - what_it_tests: the specific question this answers
    - expected_if_component_matters: what we predict if the component is important
    - priority: 1 (must-run) to 5 (nice-to-have)

    Also provide:
    - coverage_assessment: what reviewer questions these ablations answer
    - unnecessary_ablations: experiments that seem useful but won't add insight
    - suggested_order: run order optimized for maximum early information
