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.

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 | $0.00098 | $0.03203 |
| Opus 5 | $0.00049 | $0.01602 |
| Sonnet 5 | $0.00020 | $0.00641 |
| Haiku 4.5 | $0.00010 | $0.00320 |
Grade A, and why
perplexity-search 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 11d 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.
This is a copy
100% identical to perplexity-search — 1 line differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 447 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Perplexity Search
Overview
Perform AI-powered web searches using Perplexity models through LiteLLM and OpenRouter. Perplexity provides real-time, web-grounded answers with source citations, making it ideal for finding current information, recent scientific literature, and facts beyond the model's training data cutoff.
This skill provides access to all Perplexity models through OpenRouter, requiring only a single API key (no separate Perplexity account needed).
When to Use This Skill
Use this skill when:
- Searching for current information or recent developments (2024 and beyond)
- Finding latest scientific publications and research
- Getting real-time answers grounded in web sources
- Verifying facts with source citations
- Conducting literature searches across multiple domains
- Accessing information beyond the model's knowledge cutoff
- Performing domain-specific research (biomedical, technical, clinical)
- Comparing current approaches or technologies
Do not use for:
- Simple calculations or logic problems (use directly)
- Tasks requiring code execution (use standard tools)
- Questions well within the model's training data (unless verification needed)
Quick Start
Setup (One-time)
-
Get OpenRouter API key:
- Visit https://openrouter.ai/keys
- Create account and generate API key
- Add credits to account (minimum $5 recommended)
-
Configure environment:
# Set API key export OPENROUTER_API_KEY='sk-or-v1-your-key-here' # Or use setup script python scripts/setup_env.py --api-key sk-or-v1-your-key-here -
Install dependencies:
uv pip install litellm -
Verify setup:
python scripts/perplexity_search.py --check-setup
See references/openrouter_setup.md for detailed setup instructions, troubleshooting, and security best practices.
Basic Usage
Simple search:
python scripts/perplexity_search.py "What are the latest developments in CRISPR gene editing?"
What ships with it
6 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

perplexity-search is a skill published in the GitHub repository LeonChaoX/qinyan-academic-skills (880 stars, last pushed 1mo ago), licensed MIT. It adds 98 tokens to every session and 3,203 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to perplexity-search, differing in 1 line, and is treated as a copy.
