What it does
Parameters is an agent skill from thedaviddias/Front-End-Checklist. Use when auditing URL structure or configuring search engine handling of filtered, sorted, or tracked URLs. Applies to e-commerce sites, filtered content directories, and any site appending tracking or session parameters.
Its SKILL.md is about 640 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 Sales & Support, covering E-commerce operations. 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 URL structure
- Configuring search engine handling of filtered
Example prompts
- “/parameters”
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
Parameters loads about 638 tokens when it runs, and up to ~1.8k if it reads all its reference files. Until then it costs about 58 tokens; SKILL.md has 275 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.

Limit unnecessary URL parameters
Uncontrolled URL parameters generate duplicate content that wastes crawl budget and splits PageRank across URL variants, reducing the ranking potential of the canonical-url page.
Quick Reference
- URL parameters can create thousands of duplicate URLs from a single page
- Use canonical tags to consolidate parametric URL variants to a single URL
- Strip tracking parameters (utm_*, fbclid, gclid) before setting the canonical-url
- For critical parameters (page, sort), include them in the canonical URL
Check
Identify URL parameters in use across the site (filter, sort, color, size, utm_*, page, etc.). For each parameter type, check whether the page has a canonical tag. Verify that tracking-only parameters (utm_source, fbclid, gclid) are excluded from canonical URLs. Identify URLs with 3+ parameters and review for potential crawl budget waste.
Fix
Add canonical tags to parameter-based URLs pointing to the parameter-free or preferred URL. Remove tracking parameters from canonical tags. For sorting/filtering parameters that change content meaningfully (page=2, sort=price), either canonicalize to the base URL or self-canonicalize consistently.
Explain
URL parameters like ?color=red&size=large&sort=price&utm_source=google can generate thousands of unique URLs for the same underlying content. Without canonical tags, Googlebot crawls all variants, treating each as a separate page. This wastes crawl budget, creates duplicate content, and dilutes PageRank.
Code Review
Enumerate all URL parameter patterns used across the site. For each parameter type, check if pages with those parameters have canonical tags. Verify tracking parameters (utm_*, fbclid, gclid) are stripped from canonical URLs. Check that filter/sort parameter URLs either self-canonicalize or canonical-url to the base URL. Report the total number of unique parameter combinations crawlable.
