name	figmirror
description	FigMirror mirrors the visual style of a top-conference paper figure (NeurIPS / ICML / ICLR / Nature family) onto the user's own data. Takes dirty data plus a reference figure screenshot (cropped or uncropped), preprocesses the reference crop, runs a Drawer/Reviewer loop, and outputs a camera-ready PDF plus a self-contained matplotlib script with an inline DATA SECTOR.

FigMirror (figmirror)

Use this skill when the user wants to:

• Transfer the visual style of a top-conference paper figure to their own data.
• Produce a camera-ready matplotlib figure matching a reference screenshot in style, not in data.
• Mirror 3D paper-figure references such as surfaces, scatter, trajectories, bars, layered waterfalls, or plane projections when the reference or data is actually 3D.
• Receive a self-contained .py script with editable inline data plus PNG/PDF outputs.

Required Inputs

• A reference figure screenshot (PNG/JPG). It may include margins, captions, neighboring panels, or page text; Stage 0 preprocesses it.
• The user's data in any parseable form: pasted table, CSV, TSV, markdown table, or dirty terminal text.
• A working directory for iteration artifacts.

3D Insert Gate

Enable references/three-d-prompting.md only when the user asks for a 3D figure, the reference is visibly 3D, or the parsed data requires a 3D encoding such as x/y/z, surfaces, trajectories, layered profiles, closed objects, 3D small multiples, 3D bars, or plane projections. Do not use this insert to turn an ordinary 2D task into 3D.

Architecture

• Python runner owns UI lifecycle, cancellation, Stage-0 bootstrap, optional data-gen, and launching the main Codex process.
• The top-level Codex process is Orchestrator only. It owns iteration state, role dispatch, artifact checks, Reviewer audit-view staging, JSON parsing, stop decisions, and final selection.
• Drawer runs as the named figmirror-drawer custom subagent through spawn_agent with fork_context=false. It writes each iteration's matplotlib script, render, notes, and floor self-check in the staged workdir.
• Reviewer runs as the named figmirror-reviewer custom subagent through spawn_agent with fork_context=false. It sees only the staged audit view: the far-view composite, full-resolution reference/draft near views, the Reviewer prompt, the aesthetic library, and bounded history. It returns strict JSON including boxes; the Orchestrator writes that JSON to audit_iter<N>.json and deterministically renders annotated.png plus notes.md for the next Drawer.
• 3D flow uses the standard Orchestrator plus named Drawer/Reviewer subagents, and optional candidate-scoring path for strict reproduction.

Workflow

1. Read these bundled references from this skill directory:
   • references/preprocessor.md for Stage-0 reference crop cleanup.
   • references/orchestrator-codex.md for loop wiring and stop conditions.
   • references/drawer.md for the Drawer instructions.
   • references/reviewer.md for the Reviewer instructions.
   • references/aesthetic-library.md for the L2 convention library.
   • references/three-d-prompting.md only when the 3D insert gate is enabled.
2. Preserve the uploaded reference as inputs/reference_raw.png, then run the reference preprocessor to write inputs/reference_clean.png, inputs/reference_crop_check.png, and inputs/reference_crop_report.md.
3. Echo the parsed data structure before drawing. If the user explicitly asked you to make up data or proceed without confirmation, record that in data_echo.md and continue; otherwise ask for confirmation.
4. When the 3D insert gate is enabled, stage references/three-d-prompting.md plus references/three-d/ beside the normal prompts. The router selects exactly one mode file: three-d/style-transfer.md for ordinary user-data figures, or three-d/strict-reproduction.md for reproduction, comparison, or candidate/control replacement. For strict 3D reproduction runs that need quantitative candidate diagnosis, also stage scripts/score_3d_candidates.py; do not use that scorer for ordinary style transfer. The top-level Orchestrator owns final selection and must run the selected mode's rendered-image gates before copying any candidate to the final figure. Always stage scripts/figannot.py; it is the deterministic operator for building audit composites and drawing Reviewer boxes.
5. In Codex, the top-level agent follows references/orchestrator-codex.md and spawns figmirror-drawer for each iter. The Drawer writes figure_iter<N>.py, img_iter<N>.png, notes_iter<N>.md, and floor_selfcheck_iter<N>.txt; the Orchestrator verifies those files before any Reviewer handoff.
6. Stage audit_view_<N>, run scripts/figannot.py compose to create composite.png and review_prompt.txt, and spawn figmirror-reviewer as described in . The Reviewer sees the composite far view, full-resolution reference/draft near views, aesthetic library, optional 3D insert, bounded anchors/changed lists, and prior audit JSON, then returns strict JSON for the Orchestrator to persist.

Non-Negotiables

• The reference is a style anchor, not a layout-number anchor — but the chart type and signature motifs ARE style, not layout numbers. Reproduce them.
• Preserve the source's signature visual motifs — chart type, colorbars, shaded/error bands, error bars, streamline fields, stacked/offset construction, insets. Dropping or flattening one is a fidelity failure, not a simplification. Only the data values and labels change to match data.txt.
• inputs/reference_raw.png is the preserved upload; inputs/reference_clean.png is the Stage-0 crop used for L1 measurement.
• Every visual choice must be grounded in L1 (reference image) or L2 (references/aesthetic-library.md); L3 opinion is disallowed.
• Do not modify a property on the Reviewer preserve list outside its L1/L2 class.
• Do not expose data.txt or source code to the Reviewer audit view.
• Keep the final script self-contained and set plt.rcParams["pdf.fonttype"] = 42.
