Codex Image Gallery Agent Skill

Start or reuse a self-contained local web gallery for browsing Codex-generated images. Use when the user asks to browse Codex generated images, open a local image gallery, inspect ~/.codex/generated_images, view a Codex image output folder, or browse image files produced by Codex.

Codex Image Gallery

Start a local browser gallery for Codex image outputs. This skill is self-contained: the server lives in scripts/server.mjs, and the UI template lives in assets/index.html.

Quick Start

Run commands from this skill directory, the directory containing this SKILL.md.

node scripts/server.mjs

The server prints the actual URL. It starts at http://127.0.0.1:8765/ and tries later ports if the default is occupied.

Workflow

Check the default URL first:

   node -e 'fetch("http://127.0.0.1:8765/api/images").then(r => r.json()).then(j => console.log(j.rootPath, j.items.length)).catch(() => process.exit(1))'

If this succeeds, reuse the running server at http://127.0.0.1:8765/.

If the API check fails, check for a running server process:

   pgrep -fl 'node .*server\.mjs' || true

When a process exists but the default URL fails, inspect its stdout or try likely later ports because the server auto-increments when a port is occupied.

Verify any reused URL before reporting success:

   node -e 'fetch("http://127.0.0.1:8765/api/images").then(r => r.json()).then(j => console.log(j.rootPath, j.items.length))'

If the server chose another port, use that port.

Start the server if none is running:

   node scripts/server.mjs

Keep the process running for the user and read stdout for the URL.

Open the browser unless the user asks for URL-only:

   open http://127.0.0.1:8765/

Image Root

Default image root:

~/.codex/generated_images

Use a different folder with:

GALLERY_ROOT=/path/to/images node scripts/server.mjs

Validation

Before declaring the skill healthy after edits, run:

node --check scripts/server.mjs

Then start the server and verify:

GET /api/images returns JSON with rootPath and items
/images/<relative-path> returns image content for at least one listed item
The page loads from the bundled assets/index.html

Response

Report the URL, image root, whether the server was reused or newly started, and any verification failure. Keep the answer short.

Canvas Design

Create beautiful visual art in .png and .pdf documents using design philosophy. You should use this skill when the user asks to create a poster, piece of art, design, or other static piece. Create original visual designs, never copying existing artists' work to avoid copyright violations.

Creating algorithmic art using p5.js with seeded randomness and interactive parameter exploration. Use this when users request creating art using code, generative art, algorithmic art, flow fields, or particle systems. Create original algorithmic art rather than copying existing artists' work to avoid copyright violations.

Improves the quality of images, especially screenshots, by enhancing resolution, sharpness, and clarity. Perfect for preparing images for presentations, documentation, or social media posts.

Downloads videos from YouTube and other platforms for offline viewing, editing, or archival. Handles various formats and quality options.

Lightweight WSI tile extraction and preprocessing. Use for basic slide processing tissue detection, tile extraction, stain normalization for H&E images. Best for simple pipelines, dataset preparation, quick tile-based analysis. For advanced spatial proteomics, multiplexed imaging, or deep learning pipelines use pathml.

Microscopy data management platform. Access images via Python, retrieve datasets, analyze pixels, manage ROIs/annotations, batch processing, for high-content screening and microscopy workflows.

Python library for working with DICOM (Digital Imaging and Communications in Medicine) files. Use this skill when reading, writing, or modifying medical imaging data in DICOM format, extracting pixel data from medical images (CT, MRI, X-ray, ultrasound), anonymizing DICOM files, working with DICOM metadata and tags, converting DICOM images to other formats, handling compressed DICOM data, or processing medical imaging datasets. Applies to tasks involving medical image analysis, PACS systems, radiology workflows, and healthcare imaging applications.

This skill should be used when working with pre-trained transformer models for natural language processing, computer vision, audio, or multimodal tasks. Use for text generation, classification, question answering, translation, summarization, image classification, object detection, speech recognition, and fine-tuning models on custom datasets.

How to use it

Copy the folder

Take daymade/codex-image-gallery from the repository into ~/.claude/skills for personal use, or into .claude/skills inside a project.

Check the name does not clash

The agent identifies a skill by the name field in its header. Two skills with the same name cannot sit side by side — one of them will be ignored.
