parallel-deep-research

A skill for unusually detailed, multi-step internet research. It is intended for requests that explicitly ask for deep or exhaustive research.

In plain words
What is it for?
It is for comprehensive reports and thorough investigations that need multiple research steps and can continue across turns.
Why use it?
It helps avoid using a slower research process for ordinary lookups and explains what to do if the required command-line tool is outdated.

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

parallel-deep-research 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 yesterday.

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 — 109 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Deep Research

Research topic: $ARGUMENTS

Requires parallel-cli ≥ 0.3.0. If any command below errors with no such option, no such command, or unrecognized arguments, the user is on an older CLI. Tell them to run parallel-cli update (or pipx upgrade parallel-web-tools if installed via pipx), then retry.

ONLY use this skill when the user explicitly requests deep/exhaustive research. Deep research is 10-100x slower and more expensive than parallel-web-search. For normal "research X" requests, quick lookups, or fact-checking, use parallel-web-search instead.

Step 1: Start the research

Choose a descriptive filename based on the topic (e.g., ai-chip-market-2026, react-vs-vue-comparison). Use lowercase with hyphens, no spaces. Reuse this base name in step 2 as -o "$FILENAME".

parallel-cli research run "$ARGUMENTS" --processor pro-fast --text --no-wait --json

The --text flag tells the API to return a markdown report (with inline citations) when the task completes, instead of the default structured JSON. Use it for narrative/report-style requests, which is what most users want from "deep research." Drop --text if the user explicitly wants structured JSON output.

Optional with --text: pass --text-description "Keep under 1500 words, focus on M&A activity" to steer length, format, or focus.

If this is a follow-up to a previous research or enrichment task where you know the interaction_id, add context chaining:

parallel-cli research run "$ARGUMENTS" --processor lite-fast --text --no-wait --json --previous-interaction-id "$INTERACTION_ID"

By chaining interaction_id values across requests, each follow-up question automatically has the full context of prior turns — so you can drill deeper without restating what was already researched. Use a lighter processor (lite-fast or base-fast) for follow-ups since the heavy lifting was done in the initial turn.

This returns instantly. Do NOT omit --no-wait — without it the command blocks for minutes and will time out.

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-deep-research is a skill published in the GitHub repository parallel-web/parallel-cursor-plugin (3 stars, last pushed 3mo ago), licensed MIT. It adds 76 tokens to every session and 1,528 once invoked, about $0.0004 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 2026-08-31.
