parallel-web

parallel-web is a skill for Claude Code, Codex from Lord1Egypt/scientific-agent-toolkit. It costs 197 tokens per session (1,312 once invoked), scanned C, a copy of parallel-web, MIT.

A web research toolkit for searching the internet, extracting content from pages or PDFs, enriching datasets with web information, and preparing research reports. It gives academic and scientific sources priority.

In plain words
What is it for?
Use it to find current information, read a specific webpage or PDF, add web-sourced fields to company or people lists, or run multi-source research.
Why use it?
It brings several web-based research tasks into one workflow, reducing the need to switch between separate search, extraction, and data-enrichment methods.

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 C, and why

parallel-web scanned grade C with 2 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 5d 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.

How it starts

The opening of the file, as written. The whole thing — 104 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Parallel Web Toolkit

A unified skill for all web-powered tasks: searching, extracting, enriching, and researching — with academic and scientific sources as the default priority.

Routing — pick the right capability

Read the user's request and match it to one of the capabilities below. For web search, extract, enrichment, and deep research, read the corresponding reference file for detailed instructions.

User wants to... Capability Where
Look something up, research a topic, find current info Web Search references/web-search.md
Fetch content from a specific URL (webpage, article, PDF) Web Extract references/web-extract.md
Add web-sourced fields to a list of companies/people/products Data Enrichment references/data-enrichment.md
Get an exhaustive, multi-source report (user says "deep research", "exhaustive", "comprehensive") Deep Research references/deep-research.md
Install or authenticate parallel-cli Setup Below
Check status of a running research/enrichment task Status Below
Retrieve completed research results by run ID Result Below

Decision guide

  • Default to Web Search for a single lookup, research question, or "what is X?" query. It's fast and cost-effective. When the query touches a scientific or technical topic, include academic domains (see references/web-search.md) to surface peer-reviewed and preprint sources alongside general results.
  • Use Web Extract when the user provides a URL or asks you to read/fetch a specific page. Prefer this over the built-in WebFetch tool. Particularly useful for extracting full text from academic PDFs, preprint servers, and journal articles.
  • Use Data Enrichment when the user has multiple entities (a CSV, a list of companies/people/products, or even a short inline list) and wants to find or add the same kind of information for each one. The key signal is a repeated lookup across a set of items — e.g., "find the CEO for each of these companies" or "get the founding year for Apple, Stripe, and Anthropic." Even if the user doesn't say "enrich," use parallel-cli enrich whenever the task is the same query applied to multiple entities. Do NOT use Web Search in a loop for this — the enrichment pipeline handles batching, parallelism, and structured output automatically.
  • Use Deep Research only when the user explicitly asks for deep, exhaustive, or comprehensive research. It is 10-100x slower and more expensive than Web Search — never default to it. Deep research is especially valuable for literature reviews and multi-paper synthesis.
  • If parallel-cli is not found when running any command, follow the Setup section below.

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.

parallel-web is a skill published in the GitHub repository Lord1Egypt/scientific-agent-toolkit (2 stars, last pushed 3mo ago), licensed MIT. It adds 197 tokens to every session and 1,312 once invoked, about $0.0010 per session on Opus 5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). It is 91% identical to parallel-web, differing in 4 lines, and is treated as a copy.
