perplexity-web-research

perplexity-web-research is a skill for Claude Code, Codex from xpepper/perplexity-agent-skill. It costs 73 tokens per session (1,479 once invoked), scanned A, original, MIT.

A way to use the Perplexity command-line tool for web searches, detailed research, reasoning, and independent checks. It supports different models for quick lookups, thorough research, and reasoning tasks.

In plain words
What is it for?
Use it to research changing topics, compare information, check an answer independently, or analyze a complex question.
Why use it?
It provides current external information or a second analysis when the usual research method is not enough or when a decision needs validation.

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

perplexity-web-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 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.

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

Perplexity Web Research

Use the llm CLI with Perplexity plugin for web research, deep reasoning, and independent validation.

Quick Start

llm -m sonar 'your question here'

Model Selection

Model Use Case Context Web Search
sonar Quick lookups, general questions (default) 128k
sonar-pro Thorough answers, detailed research 200k
sonar-deep-research Complex multi-faceted research 128k
sonar-reasoning Step-by-step reasoning questions 128k
sonar-reasoning-pro Advanced reasoning with detail 128k
r1-1776 Reasoning without web search 128k

Start with sonar for most queries. Upgrade to other models when you need comprehensive coverage (sonar-pro), complex synthesis (sonar-deep-research), or logical reasoning (sonar-reasoning/sonar-reasoning-pro).

For detailed selection criteria, decision flowcharts, and examples, see references/model-selection-guide.md.

When to Use

Use this skill in three primary scenarios:

1. Current or External Knowledge

When you need up-to-date information and intentionally want to use Perplexity instead of standard web fetch tools:

  • Documentation lookups: Current API docs, library references, framework guides
  • Library versions: "What's the latest version of X?"
  • Recent changes: "What changed in Y version 2.0?"
  • Error research: Unfamiliar error messages or stack traces
  • Technology verification: "Does X support Y feature?"
  • Current events: Recent news, announcements, releases
  • Fact checking: Information that may have changed since training cutoff

2. Second Opinions

When you want an independent perspective before committing to a decision or approach:

  • Architecture decisions: "What are the trade-offs between approach A and B?"
  • Technology choices: "Should I use X or Y for this use case?"
  • Design validation: "Is this approach considered best practice?"
  • Problem verification: "Am I thinking about this problem correctly?"
  • Alternative perspectives: "What other ways could this be solved?"

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.
