explain

Get clear explanations of concepts, code, or technical topics with web-grounded accuracy from Perplexity.

Instructions

Clear explanations of concepts, code, or technical topics using Perplexity with web-grounded accuracy. Trigger: 'perplexity explain'.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
conceptYesWhat to explain (code, concept, or technical topic)
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries the full burden. It mentions using Perplexity with web-grounded accuracy, which adds context, but does not disclose behavioral details like auth needs, rate limits, or side effects.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is concise: two sentences, front-loaded with purpose and method, zero fluff. Every sentence earns its place.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a single-parameter tool with no output schema or annotations, the description is adequate but lacking detail on return format, depth of explanations, or examples. It covers the core but misses some completeness.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

With 100% schema coverage, the schema already describes the 'concept' parameter. The description's mention of 'concepts, code, or technical topics' aligns with the schema but adds no new meaning beyond it, so baseline 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool's purpose: providing clear explanations of concepts, code, or technical topics using Perplexity with web-grounded accuracy. The verb 'explain' and resource types are specified, distinguishing it from siblings like 'ask' or 'deep_research', though not explicitly.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description includes a trigger phrase ('perplexity explain') which implies when to use it, but lacks explicit guidance on when not to use it or specific alternatives among siblings like 'search' or 'ask'.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
