What it does
Trailing Slash is an agent skill from thedaviddias/Front-End-Checklist. Use when applies to all static and dynamic websites. Use when auditing a site for duplicate content, setting up a new site, or after migrating platforms that changed URL conventions.
Its SKILL.md is about 540 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`).
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
- Applies to all static and dynamic websites
- Auditing a site for duplicate content
- Setting up a new site
- After migrating platforms that changed URL conventions
Example prompts
- “/trailing-slash”
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
Trailing Slash loads about 537 tokens when it runs, and up to ~1.5k if it reads all its reference files. Until then it costs about 49 tokens; SKILL.md has 240 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.

Use trailing slashes consistently
Inconsistent trailing slashes create duplicate content — Google sees /page and /page/ as two separate URLs competing for the same ranking, splitting PageRank between them.
Quick Reference
- Pick one convention — trailing slash or no trailing slash — and enforce it site-wide with 301 redirects
- Both
/page/and/pagemust not return HTTP 200; one must redirect to the other - Set
rel="canonical"to the preferred version on all pages - Ensure all internal links, sitemaps, and canonical tags use the same convention
Check
For a sample of URLs, test both the trailing-slash and non-trailing-slash versions. Both should NOT return HTTP 200 — one must 301-redirect to the other. Check that internal links, sitemap <loc> values, and canonical tags all use the same convention consistently.
Fix
Choose a canonical URL convention. Add server or framework redirect rules so the non-preferred variant permanently redirects (301) to the preferred one. Update all internal links, canonical tags, and sitemap entries to use the preferred format.
Explain
Explain why /page and /page/ are treated as distinct URLs by default, how this creates duplicate content, and how 301 redirects and canonical tags resolve the ambiguity.
Code Review
Review metadata generation, rendered HTML, structured data, and response headers related to Use trailing slashes consistently. Flag exact routes or templates where search-facing output violates the rule, and describe how to verify the final page output.
