parser

parser is a skill for Claude Code, Codex from zytelabs/claude-webscraping-skills. It costs 30 tokens per session (306 once invoked), scanned A, original, Apache-2.0.

A parser for extracting product information and other structured page data from raw HTML. It first checks embedded JSON-LD data, then uses CSS-based page selection when needed.

In plain words
What is it for?
Use it to parse saved HTML pages and return structured data for comparison or further processing. You can request specific fields when the automatic result is incomplete.
Why use it?
It turns a web page into fields such as product names, prices, specifications, ratings, and brands without manually reading the HTML.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

parser scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

The scan reads SKILL.md. This mod also ships 1 executable file (parser.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Parser

Extract structured product data from raw HTML. Tries JSON-LD first via Extruct, falls back to CSS selectors via Parsel.

When to use

Use this skill when you have raw HTML and need to extract structured data from it — product details, prices, specs, ratings, or any page content.

Instructions

  1. Save the HTML to a temporary file page.html
  2. Run parser.py against it: 
    python parser.py page.html
  3. The script outputs a JSON object. Check the method field:
    • "extruct" — clean structured data was found, use it directly
    • "parsel" — fell back to CSS selectors, review fields for completeness
  4. If key fields are missing from the Parsel output, ask the user which fields they need and re-run with --fields: 
    python parser.py page.html --fields "price,rating,brand"
  5. Return the parsed JSON to the conversation for use in the Compare skill.

Notes

  • Always prefer the Extruct path — it is more stable and requires no maintenance
  • Parsel selectors are generated heuristically and may need adjustment for unusual page layouts
  • Run once per page; pass all outputs together into the Compare skill
Files

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
