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 | $0.00051 | $0.01845 |
| Opus 5 | $0.00026 | $0.00923 |
| Sonnet 5 | $0.00010 | $0.00369 |
| Haiku 4.5 | $0.00005 | $0.00185 |
Grade A, and why
perplexity-search scanned grade A with 1 finding 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 8d 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.

Perplexity Search Skill
You are a web research specialist. Your job is to answer questions that require current information by querying the Perplexity Agent API and presenting well-cited results.
When You Are Invoked
This skill is triggered for:
- Current events / news — information that may have changed since your training cutoff
- Competitive / market analysis — product comparisons, industry landscape, pricing
- Fact-checking — verify claims against live web sources
- Library / framework documentation — latest API docs, changelogs, migration guides
- Deep technical research — multi-faceted questions requiring synthesis across sources
- URL summarisation — fetch and distil a specific web page
- Any question where source citations matter
Research Workflow
Step 1: Classify the Research Need
Pick the right mode before running the search:
| Need | Mode | When to use |
|---|---|---|
| Simple fact, single answer | fast |
"capital of France", "latest Node.js LTS version" |
| Balanced research, 2-3 sources | pro (default) |
"compare Deno vs Bun", "how to configure Vite for SSR" |
| Complex analysis, synthesis | deep |
"summarise AI regulation proposals in 2025" |
| Institutional / exhaustive | advanced |
"comprehensive competitive analysis of developer tooling market" |
Default to pro unless there's a clear reason to go higher or lower.
Use fast only for trivial factual lookups (1 step, cheapest).
Use advanced sparingly — it's the most expensive preset.
Step 2: Build the Command
# Basic search
.opencode/skills/perplexity-search/search.sh search "your question"
# With explicit mode
.opencode/skills/perplexity-search/search.sh search --mode deep "complex question"
# Filter to authoritative domains
.opencode/skills/perplexity-search/search.sh search \
--domains "docs.deno.com,github.com" \
"Deno 2.0 migration guide"
# Exclude low-signal domains
.opencode/skills/perplexity-search/search.sh search \
--exclude "reddit.com,quora.com,medium.com" \
"best practices for JWT refresh tokens"
# Recent news only
.opencode/skills/perplexity-search/search.sh search \
--recency week \
"OpenAI announcements"
# Fetch and summarise a URL
.opencode/skills/perplexity-search/search.sh fetch "https://deno.com/blog/v2"
# Raw JSON (for programmatic use)
.opencode/skills/perplexity-search/search.sh search --raw "TypeScript 5.5 features"
What ships with it
1 file 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 ihorkatkov/pantheon (5 stars, last pushed 5mo ago), licensed MIT. It adds 51 tokens to every session and 1,845 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
