What it does
Breadcrumb is an agent skill from thedaviddias/Front-End-Checklist. Use when auditing metadata, crawlability, structured data, or indexability related to Implement valid BreadcrumbList schema. Verify the rendered HTML and HTTP response rather than relying only on source files.
Its SKILL.md is about 420 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 Marketing & SEO, covering Technical SEO and Schema markup. 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 metadata
- Structured data
- Indexability related to Implement valid BreadcrumbList schema
Example prompts
- “/breadcrumb”
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
Breadcrumb loads about 423 tokens when it runs, and up to ~1.1k if it reads all its reference files. Until then it costs about 55 tokens; SKILL.md has 162 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.

Implement valid BreadcrumbList schema
Breadcrumbs help search engines understand your site's structure and often appear in search results, improving navigation and click-through rates.
Quick Reference
- Add
BreadcrumbListstructured data only when the page has a visible, meaningful breadcrumb trail - Ensure the breadcrumb path matches the visible trail and the site's logical hierarchy
- Use JSON-LD to mark up each item in the breadcrumb trail correctly
Check
Verify that the page contains valid BreadcrumbList structured data matching the visible breadcrumbs.
Fix
Implement a JSON-LD script that defines each level of the page's hierarchy using ListItem properties.
Explain
Explain how breadcrumb schema replaces URLs in search results with a more readable navigation path.
Code Review
Review metadata generation, rendered HTML, structured data, and response headers related to Implement valid BreadcrumbList schema. Flag exact routes or templates where search-facing output violates the rule, and describe how to verify the final page output.
For full implementation details, code examples, and framework-specific guidance,
