Rebuilds or restyles diagrams as editable native Visio shapes from a reference image or .vsdx file, then exports .vsdx, PNG, SVG, PDF or PPTX.

  • Works in 6 steps: Inspect inputs. → Decode the reference image. → Prefer Visio automation for native edits. → …
  • Recreating a diagram from a PNG, JPG or screenshot as an editable Visio file
  • SKILL.md covers Core Rule, Workflow, Implementation Pattern and Safety Checklist, plus 2 more sections
  • Runs PowerShell scripts from its folder

What it does

The core rule is that a rebuild must produce real Visio content, never a page with the reference picture pasted in. A reference image may serve only as a temporary tracing layer, and it has to be removed or hidden before delivery so the .vsdx keeps native shapes, text, connectors and groups. The .vsdx file is treated as the source of truth, and PNG, SVG, PDF or PPTX exports come only after the page has been rebuilt and checked.

The workflow starts by confirming paths, exporting the current page to PNG, inspecting the package and backing up the target before any write. The reference is then decoded into an inventory of containers, titles, boxes, icons, charts, connectors and captions, with the canvas and each major panel calibrated by explicit bounds before small details are drawn. Edits go through Visio COM automation on Windows, with package XML edits kept for narrow, deterministic changes. PowerShell scripts cover page tools, a rebuild scaffold and format export, and a reference file holds rebuild guidelines.

When your agent uses it

  • Recreating a diagram from a PNG, JPG or screenshot as an editable Visio file
  • Changing colors, typography or layout in an existing .vsdx
  • Fixing shifted or overlapping submodules in a multi-panel scientific figure
  • Exporting a finished Visio page as PDF, SVG or PPTX for a paper or slides

Example prompts

  • “Rebuild the model figure in ./figs/overview.png as an editable Visio diagram.”
  • “Restyle ./figs/pipeline.vsdx to match the colors of this reference image and export a PDF.”
  • “The panels in my architecture figure overlap. Recalibrate the layout and export SVG and PNG versions.”

Requirements

  • Windows with Microsoft Visio installed
  • PowerShell

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

  1. Inspect inputs.
  2. Decode the reference image.
  3. Prefer Visio automation for native edits.
  4. Use package XML edits only for narrow, deterministic changes.
  5. Export requested formats from the verified Visio source.
  6. Verify without overtrusting a single signal.

What it can do on your machine

Read from SKILL.md and the folder at commit 816960d. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 3 files in scripts/ (PowerShell), which the agent can run.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Visio Image Rebuilder loads about 2k tokens when it runs, and up to ~4.6k if it reads all its reference files. Until then it costs about 146 tokens; SKILL.md has 966 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~146
When it runs · the whole SKILL.md, loaded when a task matches
~2k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~4.6k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

description
Rebuild or restyle editable Microsoft Visio diagrams from reference images and existing .vsdx files, then export deliverables as .vsdx, PNG, SVG, PDF, or PPTX. Use when the user asks Codex to open Visio, recreate a diagram from a PNG/JPG/screenshot/reference image, match a scientific model figure, update colors/typography/layout in a .vsdx, calibrate panel coordinates to avoid shifted or overlapping submodules, or make publication/presentation outputs while preserving Visio native editable shapes rather than embedding the reference image as a flat picture.

Visio Image Rebuilder

Core Rule

Recreate the reference as editable Visio content. Do not satisfy a rebuild request by inserting the whole reference image into the page. Embedding the reference image is only allowed as a temporary locked tracing layer if it is removed or hidden before delivery and the final .vsdx remains native shapes, text, connectors, and groups.

Treat .vsdx as the source of truth. Export PNG, SVG, PDF, or PPTX only after the Visio page has been rebuilt or restyled and checked for native editability.

Workflow

  1. Inspect inputs.

    • Confirm paths for the target .vsdx, reference image, requested output formats, and output directory.
    • Export the current Visio page to PNG before editing when a target file already exists.
    • Inspect the .vsdx package for pages, media entries, and shape counts.
    • Back up the target file before any write.
    • If Visio is already open, close only the target document or ask before terminating a stuck process.

  2. Decode the reference image.

    • Identify page orientation, panel boundaries, module colors, captions, text hierarchy, arrows, dashed lines, and repeated motifs.
    • Build an object inventory: containers, titles, process boxes, icons, charts, graphs, equations, connectors, captions.
    • Calibrate the canvas first, then calibrate each major panel or subpanel with explicit top-left bounds or four corner points.
    • Draw panel internals in panel-local normalized coordinates whenever the figure has dense multi-panel content.
    • Decide whether the task is a full rebuild, color/style transfer, local edit, or export-only job.
    • For dense scientific figures, first create a coarse panel map, then draw panel internals. Do not start with small decorative details.

  3. Prefer Visio automation for native edits.

    • Use COM automation on Windows when Visio is installed.
    • Use DrawRectangle, DrawOval, DrawLine, Page.Import only for small source assets, and shape cells such as FillForegnd, LineColor, LineWeight, Char.Size, Char.Color, Rounding.
    • Use explicit coordinates and IDs for fragile edits.
    • Keep grouped structure meaningful: major panels, submodules, repeated blocks, legends.
    • For nested modules, use helpers such as RectRel, TextRel, LineRel, and OvalRel so child shapes are constrained by their calibrated parent panel.

  4. Use package XML edits only for narrow, deterministic changes.

    • XML patching is appropriate for recoloring existing shapes, replacing font tables, or changing known cell values.
    • Preserve Visio XML ordering: shape-level Cell nodes should be before Section, Text, or child Shapes.
    • Avoid rebuilding complex geometry by raw XML unless COM automation is unavailable.

  5. Export requested formats from the verified Visio source.

    • Use scripts/visio_page_tools.ps1 for export-only jobs.
    • Use scripts/visio_rebuild_scaffold.ps1 with -ExportFormats for rebuilds that should immediately create deliverables.
    • Prefer SVG for vector web/manuscript handoff, PDF for review/print, and PPTX for presentation decks.
    • For PPTX, use PowerPoint COM when available; the generated slide contains the Visio page render, usually inserted from SVG.

  6. Verify without overtrusting a single signal.

    • Export at least one preview after editing when possible.
    • Inspect the .vsdx package to confirm that no full-size reference PNG/JPG was left in visio/media.
    • Check shape count and representative text labels.
    • Check that major panels do not overlap and that child shapes stay within their intended panel bounds.
    • Check every requested output file exists and is non-empty.
    • If Visio automation hangs, stop safely, close the document if possible, and report whether the file was actually modified.

Implementation Pattern

For full rebuilds, generate a script that:

  • Opens the target .vsdx with Visio COM.
  • Saves a timestamped or descriptive backup.
  • Clears or duplicates the page depending on user preference.
  • Sets page size to match the reference aspect ratio.
  • Draws native shapes in top-left reference coordinates converted to Visio coordinates.
  • Defines calibrated panel bounds for complex regions and uses panel-local coordinates for their internals.
  • Adds reusable helpers for rectangles, text boxes, ovals, lines, arrows, mini charts, graph nodes, and image-like stacks.
  • Saves the document and exports requested formats.

Start from scripts/visio_rebuild_scaffold.ps1 when building a full reconstruction script. Copy it into the workspace and customize the Draw-ReferenceFigure function rather than editing the skill copy.

For style transfer, generate a script that:

  • Reads existing shape IDs, text, approximate geometry, fill, and line colors.
  • Maps known modules to target palettes by text and group context.
  • Applies fills, borders, text colors, line patterns, and font changes to existing shapes.
  • Avoids repositioning unless the user asks for layout changes.
  • Exports only after the .vsdx has been saved and inspected.

For export-only requests, run:

powershell
powershell -ExecutionPolicy Bypass -File scripts\visio_page_tools.ps1 `
  -VsdxPath "C:\path\figure.vsdx" `
  -ExportFormats svg,pdf,pptx `
  -OutputDir "C:\path\exports" `
  -InspectPackage

For rebuild plus multi-format export, run:

powershell
powershell -ExecutionPolicy Bypass -File scripts\visio_rebuild_scaffold.ps1 `
  -VsdxPath "C:\path\figure.vsdx" `
  -PageW 16 `
  -PageH 9 `
  -RefW 1600 `
  -RefH 900 `
  -PreviewPath "C:\path\exports\figure.png" `
  -ExportFormats svg,pdf,pptx `
  -OutputDir "C:\path\exports"

Safety Checklist

  • Back up before writing outside the workspace.
  • Close any open Visio document that locks the target file before direct package edits.
  • Never delete or revert unrelated user files.
  • If a previous attempt embedded the reference image, restore from backup or remove the image shape before continuing.
  • Tell the user clearly whether the final file is native editable shapes or a flat embedded image.
  • Tell the user when PPTX export is a rendered slide rather than native PowerPoint shapes.

Acceptance Criteria

A Visio rebuild is acceptable only when:

  • Main panel positions, flow direction, captions, and module hierarchy match the reference at first glance.
  • Major panels are aligned to calibrated bounds, with no obvious submodule drift, collision, or cross-panel overlap.
  • Text remains editable and uses a consistent academic font, usually Times New Roman.
  • Repeated motifs are represented with reusable native shapes rather than pasted raster crops.
  • The final .vsdx package has no full-page raster reference image in visio/media.
  • Requested PNG/SVG/PDF/PPTX deliverables were exported from the saved .vsdx and are non-empty.
  • A preview export or package inspection was performed, or the final response explicitly states why verification was skipped.

Useful Resource

Use scripts/visio_page_tools.ps1 for common inspection, backup, preview export, multi-format export, and package checks. Use scripts/visio_export_formats.ps1 when a custom task script needs reusable export helpers. Use scripts/visio_rebuild_scaffold.ps1 as the starting point for native-shape drawing scripts; it includes both global top-left helpers and panel-local calibrated helpers. Read references/rebuild-guidelines.md when a task requires a full figure reconstruction or careful one-to-one scientific diagram matching.
