When your agent uses it
- Auditing slow page loads
- Rendering delays related to Optimize Google Tag Manager implementation
Example prompts
- “/gtm-present”
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
Gtm Present loads about 409 tokens when it runs, and up to ~1.5k if it reads all its reference files. Until then it costs about 58 tokens; SKILL.md has 157 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.

Optimize Google Tag Manager implementation
An unoptimized GTM setup can lead to significant main-thread blocking and increased page weight, slowing down the overall user experience.
Quick Reference
- Place the GTM script in the
<head>but audit its impact - Minimize the number of tags and triggers to reduce execution
- Use Server-Side GTM to offload processing from the client
Check
Verify that GTM is implemented correctly and evaluate its impact on page performance using Lighthouse.
Fix
Clean up unused tags, use asynchronous loading, and consider moving to a server-side implementation.
Explain
Explain how GTM affects performance and how to balance tracking needs with speed.
Code Review
Review the routes, assets, and loading behavior that affect Optimize Google Tag Manager implementation. 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.
