ui

ui is a cursor rule for Cursor from Pranav-Karra-3301/tuck. It costs 0 tokens per session (455 once invoked), scanned A, original, MIT.

A set of interface rules for choosing colors and structuring command-line feedback, including progress messages, spinners, confirmations, and errors.

In plain words
What is it for?
Use it when designing command-line commands, status updates, progress indicators, error messages, or confirmation prompts.
Why use it?
It keeps command-line tools consistent and makes long-running or destructive actions clearer and safer.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 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 4d 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.

What it actually says

UI Rules

Color Palette

Color Usage
Cyan Primary brand, headings, emphasis
Green Success states, confirmations
Yellow Warnings, modifications
Red Errors, deletions
Dim/Gray Secondary info, paths, hints

Command Structure

Every command should follow this pattern:

prompts.intro('tuck commandname');

// ... work with spinners/progress ...

prompts.note("Run 'tuck next' to continue", 'Next step');
prompts.outro('Done!');

Spinners

Use for operations >100ms:

const spinner = prompts.spinner();
spinner.start('Processing files...');

try {
  await doWork();
  spinner.stop('Processed 5 files');
} catch (error) {
  spinner.stop('Failed to process');
  throw error;
}

Progress Feedback

For multi-step operations:

  1. Show what's being done
  2. Show progress (X of Y)
  3. Show completion status
prompts.log.step(`Syncing file ${i}/${total}: ${filename}`);

Confirmations

ALWAYS confirm destructive actions:

const confirmed = await prompts.confirm(
  'Delete all backups?',
  false  // Default to NO (safe option)
);

if (!confirmed) {
  prompts.cancel('Operation cancelled');
  return;
}

Error Messages

Provide helpful, actionable errors:

// Good
throw new FileNotFoundError(path, {
  suggestion: "Run 'tuck add' first to track this file"
});

// Bad
throw new Error('File not found');

Interactive Mode

Every command should support:

  • Interactive mode (default) - prompts for input
  • Non-interactive mode (--yes, --force) - for scripts

Next Steps

Always end successful operations with guidance:

prompts.note("Run 'tuck push' to upload changes", 'Next step');

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.
