A command that extracts structured information from one web page and returns it as a Markdown table or JSON. It saves the result in a local documentation folder.

Use it to collect specified fields from a URL for documentation or later processing.

It avoids copying page details by hand and gives the extracted information a consistent format.

scrape — Command for Claude Code by MarcosNahuel/antigravity-plugin-cc

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Clone the repo

git clone --depth 1 https://github.com/MarcosNahuel/antigravity-plugin-cc

Made for: Claude Code.

Or install antigravity, the plugin that ships this one along with the rest of its 2 skills, 22 commands, 1 agent.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00030	$0.00705
Opus 5.5	$0.00012	$0.00282
Sonnet 5.5	$0.00006	$0.00141
Haiku 4.5	$0.00003	$0.00071

Security

Grade A, and why

scrape 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 1mo ago.

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.

How it starts

The opening of the file, as written. The whole thing — 61 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Route this to the antigravity:agy-rescue subagent in MODE: scrape.

Raw user request: $ARGUMENTS

Routing rules

Parse the URL: the first whitespace-separated token of $ARGUMENTS that starts with http:// or https:// IS the URL. If the user wrote it without a scheme, prepend https://. If no URL is found, ask once: "What URL should I scrape?".
Parse --json: if present, set FORMAT=json and strip the flag from the remaining text. Default is FORMAT=md.
Schema/description: everything else in $ARGUMENTS (whatever is not the URL and not --json) is the schema or natural-language extraction description. If empty, agy will infer reasonable fields from the page.
Slug: build from the URL's host + first path segment (lowercase, non-alphanumeric → -, collapse repeats, trim to 60 chars).
Date: today in YYYY-MM-DD (local time).
Paths (relative to current working directory):
- OUTPUT_DIR = docs/agy/scrapes/
- WRITE_FILE = docs/agy/scrapes/<date>-<slug>.md (or .json if --json)
Pre-flight (ONE Bash call):
```
mkdir -p docs/agy/scrapes
```

Hand off: pass this header to the subagent:

MODE: scrape
URL: <url>
SCHEMA: <schema or natural-language description, or empty>
FORMAT: md|json
CWD: <absolute path to current working directory>
WRITE_FILE: docs/agy/scrapes/<date>-<slug>.md

Operating rules

The subagent invokes agy with --add-dir <CWD> so it can write the scrape report into the project.
The subagent reports:
1. Saved scrape path.
2. First ~30 lines of the scrape result (preview).
3. Number of records/fields extracted.
Present that to the user as-is.
If the URL returns non-200, the page is blocked by anti-bot, or the structure cannot be parsed, surface the error verbatim.

Notes

For JSON-API endpoints, --json is preferred. For HTML landing pages or content sites, default md table is usually more readable.
agy uses its browser/read_url tool to fetch — JS-heavy SPAs require the browser subagent (slower but works). Static HTML works via read_url (faster).
agy uses an isolated Chrome profile if it needs to render JS — no cookies, no logged-in state.
For aggressive scraping (anti-bot bypass), this is the wrong tool. Use BrightData / ScrapingBee.

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.

scrape is a command published in the GitHub repository MarcosNahuel/antigravity-plugin-cc (31 stars, last pushed 10d ago), licensed MIT. It adds 30 tokens to every session and 705 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
