explain_concept

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 does disclose genuinely useful traits — no cost and no network requirement — plus that output is short and explanatory, but it says nothing about return format, determinism, or any limits.

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

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

Two compact sentences with the key traits (free, offline) front-loaded. The trailing concept list duplicates the schema enum, so it is mildly redundant rather than wasteful.

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

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

For a trivial one-enum-param lookup with no output schema and no annotations, the description covers purpose, cost profile, and valid inputs; only the shape of the returned explanation is left implicit.

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

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

Schema description coverage is 0%, but the single parameter is a closed enum whose values are self-documenting; the description merely restates that same list without adding syntax, defaults, or fallback behavior. Baseline 3 for a fully enumerated one-param tool.

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

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

States a specific verb (explain) and resource (a TRON resource concept) and enumerates the concept domain, so an agent can distinguish it from every sibling, all of which fetch numeric/market data rather than definitions.

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

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

"Free, offline" implies when this is preferable to the network-bound sibling tools, but there is no explicit when-to-use statement, no exclusions, and no named alternative for adjacent questions.

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