What it does
Loading Indicators is an agent skill from thedaviddias/Front-End-Checklist. Use when auditing slow page loads, heavy assets, or rendering delays related to Show loading indicators. Verify the actual bottleneck in DevTools, Lighthouse, or field data before recommending changes.
Its SKILL.md is about 430 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/rule.md`).
It sits in Frontend & Design, covering Web performance and Accessibility. The repository describes itself as: 🗂 The essential checklist for modern web development, for humans and AI agents. The licence is MIT.
When your agent uses it
- Auditing slow page loads
- Rendering delays related to Show loading indicators
Example prompts
- “/loading-indicators”
What it can do on your machine
Read from SKILL.md and the folder at commit e8d14d0. 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
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
frontendchecklist.io
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
Loading Indicators loads about 434 tokens when it runs, and up to ~1.8k if it reads all its reference files. Until then it costs about 55 tokens; SKILL.md has 158 words of instructions outside code blocks.
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); files beside SKILL.md are not scanned.

Show loading indicators
Loading indicators reassure users that something is happening—without feedback, users may think the page is broken or click repeatedly, degrading experience and causing duplicate actions.
Quick Reference
- Show immediate feedback for all async operations
- Use skeletons for content, spinners for actions
- Include ARIA attributes for screen reader accessibility
- Avoid content jumps when loading completes
Check
Verify that loading states are displayed during async operations with appropriate ARIA attributes for screen readers.
Fix
Implement loading spinners/progress bars with aria-busy, aria-live, and clear visual feedback for ongoing operations.
Explain
Explain how loading indicators improve perceived performance and accessibility by communicating system status to users.
Code Review
Review the routes, assets, and loading behavior that affect Show loading indicators. Flag exact files, requests, or rendering steps that add unnecessary network, CPU, or layout cost, and describe the measurement method used to confirm the issue.
For full implementation details, code examples, and framework-specific guidance,
