What it does

Code Snippet Images is an agent skill from freekmurze/dotfiles. Generate beautiful code snippet images (PNG) for social media, tweets, LinkedIn, and documentation. Creates light-themed, macOS-style window chrome screenshots from code using HTML templates and Chrome headless. Use when asked to create code images, tweet images, snippet screenshots, code cards, or visual code examples for sharing. Supports single snippets, multi-image sets, and 2x2 grid composites.

Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including scripts and assets (for example `scripts/render.sh`).

It sits in Writing & Content, covering Social media posts. It works with macOS, LinkedIn and X (Twitter).

When your agent uses it

  • Asked to create code images
  • Snippet screenshots
  • Visual code examples for sharing

Example prompts

  • “/code-snippet-images”

Requirements

  • A Bash shell

Workflow steps

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

  1. Copy the template from assets/template.html to a temp file
  2. Replace <!-- FILENAME --> with the title bar text (e.g., filename or description)
  3. Replace <!-- CODE CONTENT --> with syntax-highlighted HTML (see Syntax Highlighting below)
  4. Render with scripts/render.sh

What it can do on your machine

Read from SKILL.md and the folder at commit 8874280. 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/ (Shell), 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

Code Snippet Images loads about 1.1k tokens when it runs. Until then it costs about 106 tokens; SKILL.md has 394 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~106
When it runs · the whole SKILL.md, loaded when a task matches
~1.1k

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.

Auto-check: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

  • NoteMentions a .env fileSKILL.md:48

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.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 394 words (~1,101 tokens).

“Generate high-resolution code snippet PNGs using HTML templates rendered with Chrome headless at 2x scale.”
