ui-snapshot.template is a command for Claude Code from evan043/claude-cli-advanced-starter-pack. It costs 0 tokens per session (557 once invoked), scanned A, original, MIT.

A command template for capturing UI snapshots, which are saved images or layout records used to compare an interface over time. It supports Playwright visual snapshots and Neovim window-layout snapshots.

In plain words
What is it for?
Update Playwright visual snapshots or capture Neovim windows and floating-window settings.
Why use it?
It helps detect unintended visual changes and records the arrangement of windows for debugging or regression checks. It also provides a shell-based alternative when browser integration is unavailable.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

ui-snapshot.template scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

The opening of the file, as written. The whole thing — 78 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Codex Runtime Compatibility

This prompt was authored for Claude-style slash workflows. In Codex runtime, adapt tool calls as follows:

  • AskUserQuestion => ask the user directly in chat.
  • WebSearch/WebFetch => use available web tools (search_query, open, find) and cite links.
  • Read/Write => use shell/filesystem tools in this workspace.
  • Claude-only MCP calls (for example Playwright MCP names) => use available equivalents or clearly state fallback.
  • Keep intent and output format identical; only adapt execution mechanics.

ui-snapshot — Codex Runtime

Capture UI snapshots for visual regression. Playwright MCP is unavailable in Codex.

Alternative: Update Playwright Snapshots via Shell

# Update all snapshots
npx playwright test --update-snapshots

# Update snapshots for specific test
npx playwright test tests/visual.spec.ts --update-snapshots

For live Playwright MCP snapshot capture, use Claude Code CLI: /ui-snapshot


description: Capture Neovim window layout snapshot for debugging

Neovim UI Layout Snapshot

Capture a complete snapshot of all Neovim windows (including floating window configs) for debugging and regression tracking.

Usage

/ui-snapshot
/ui-snapshot --json
/ui-snapshot --diff previous

Snapshot Contents

For every window:

  • Window ID and buffer number
  • Buffer name and filetype
  • Is floating (true/false)
  • Float config: row, col, width, height, zindex, border
  • Window highlight settings

Plus global state:

  • Editor dimensions (columns x lines)
  • Active window and cursor position
  • Appshell state (active section, flyout visible, rail visible)
  • Session list with running status

Running

# Capture to file
./scripts/nvim-snapshot.ps1

# Output is saved to:
# nvim-ccasp/tests/artifacts/last-snapshot.txt (human readable)
# nvim-ccasp/tests/artifacts/last-snapshot.json (machine readable)

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
