What it does
PDF Size is an agent skill from thedaviddias/Front-End-Checklist. Use when auditing a site that publishes downloadable PDFs (reports, white papers, legal documents, manuals). Applies to any site where PDFs are linked as indexable content resources.
Its SKILL.md is about 600 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 Documents & Office, covering PDF, Report writing and Policy and terms drafting. 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 a site that publishes downloadable PDFs (reports
- Legal documents
Example prompts
- “/pdf-size”
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
PDF Size loads about 597 tokens when it runs, and up to ~1.6k if it reads all its reference files. Until then it costs about 48 tokens; SKILL.md has 292 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.

Keep linked PDFs under 60 MB
PDFs larger than Googlebot's download threshold are partially crawled or skipped, meaning their content may not appear in search results even when linked from well-indexed pages.
Quick Reference
- Googlebot truncates files larger than 15 MB for crawling; 60 MB is a documented upper limit
- Large PDFs may be partially indexed or skipped entirely
- Compress PDFs before publishing: use PDF optimisation tools to reduce file size
- Add HTML landing pages alongside PDFs to ensure content is indexable
Check
Find all <a href='*.pdf'> links on the site. For each linked PDF, perform a HEAD request and check the Content-Length header. Flag any PDF exceeding 10 MB (recommend compression) or 15 MB (likely to be truncated by Googlebot).
Fix
Compress large PDFs using a PDF optimisation tool (Adobe Acrobat, Ghostscript, or Smallpdf). Remove embedded high-resolution images, fonts, and metadata not required for reading. If compression is insufficient, create an HTML page with the same content as the primary indexable version, and offer the PDF as a download.
Explain
Googlebot downloads and indexes the content of PDFs linked from your site. However, it has a file size limit for downloads — files beyond this limit are partially indexed or skipped. Large PDFs also slow down crawling and consume crawl budget. Keeping PDFs small ensures their full content appears in search results.
Code Review
Find all <a href> links with .pdf extension. For each PDF URL, perform a HEAD request and check Content-Length header value. Flag PDFs exceeding 10,485,760 bytes (10 MB) for compression review. Flag PDFs exceeding 15,728,640 bytes (15 MB) as at-risk for partial indexing. Verify PDF URLs return 200 status and appropriate Content-Type: application/pdf header.
