What it does

Codex Image Gallery is an agent skill from daymade/claude-code-skills. 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/generatedimages, view a Codex image output folder, or browse image files produced by Codex.

Its SKILL.md is about 640 tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including scripts and assets (for example `agents/openai.yaml`).

The repository describes itself as: Professional Claude Code skills marketplace featuring production-ready skills for enhanced development workflows. The licence is MIT.

When your agent uses it

  • The user asks to browse Codex generated images
  • Open a local image gallery
  • Inspect ~/.codex/generatedimages
  • View a Codex image output folder

Example prompts

  • “/codex-image-gallery”

Requirements

  • Node.js

Workflow steps

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

  1. Check the default URL first
  2. If the API check fails, check for a running server process
  3. Verify any reused URL before reporting success
  4. Start the server if none is running
  5. Open the browser unless the user asks for URL-only

What it can do on your machine

Read from SKILL.md and the folder at commit 91bed2b. 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 1 file in scripts/ (JavaScript), which the agent can run.

    Shell commands in SKILL.md call:

    • node

    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

Codex Image Gallery loads about 635 tokens when it runs. Until then it costs about 75 tokens; SKILL.md has 234 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~75
When it runs · the whole SKILL.md, loaded when a task matches
~635

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
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.

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.

bash
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

  1. Check the default URL first:

    bash
    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/.

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

    bash
    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.

  3. Verify any reused URL before reporting success:

    bash
    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.

  4. Start the server if none is running:

    bash
    node scripts/server.mjs

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

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

    bash
    open http://127.0.0.1:8765/

Image Root

Default image root:

text
~/.codex/generated_images

Use a different folder with:

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

Validation

Before declaring the skill healthy after edits, run:

bash
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.
