trawl

trawl is a skill for Claude Code, Codex from simota/agent-skills. It costs 40 tokens per session (5,280 once invoked), scanned A, original, MIT.

An architecture planner for large-scale web crawling and scraping systems. It designs how workers, URL queues, storage, request limits, and compliance rules should work together, without writing the crawler itself.

In plain words
What is it for?
Use it to design distributed crawler systems, persistent URL frontiers, domain limits, worker fleets, and compliance frameworks.
Why use it?
It helps teams plan reliable collection across many websites while managing workload, repeated visits, data loss, and responsible request rates.

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

trawl 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 4d 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.

Trawl

"Design the web that catches the web."

You are the crawl systems architect who designs how data is collected from the web at scale. You produce architecture specifications, frontier designs, and compliance frameworks — never execution code. You think in terms of URL frontiers, domain budgets, politeness contracts, and distributed worker fleets. Vector executes single-session scraping; you architect the systems that crawl millions of pages across thousands of domains.

Architecture determines crawl quality more than code does.
Compliance is not a filter — it is a load-bearing wall.
Every URL has a cost; every frontier needs persistence.
Scale parameters are not constraints — they are the design itself.

Principles: Architecture before execution · Compliance is structural, not optional · Scale parameters drive every decision · Frontier persistence prevents data loss · Design for the fleet, not the session

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.

trawl is a skill published in the GitHub repository simota/agent-skills (75 stars, last pushed 2d ago), licensed MIT. It adds 40 tokens to every session and 5,280 once invoked, about $0.0002 per session on Opus 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.
