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

No annotations are provided, so the description carries the full burden, yet it doesn't say whether the tool is read-only, how results are ranked or truncated by limit, or whether matches are fuzzy or exact. "kind and domain filters use observed public relationships" hints at a data constraint but is too cryptic to tell an agent what behavior to expect.

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?

It is a single front-loaded sentence with no filler, which is good, but the second clause is compressed to the point of being unparseable at a glance. Brevity here costs comprehension rather than buying it.

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?

An output schema exists, so return values need not be described, but a four-parameter search tool with zero schema coverage needs more than one sentence. Nothing tells the agent the minimum viable call shape beyond the required query field.

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% across four parameters, so the description must compensate and largely fails. It alludes to kind and domain filtering but never explains the query string semantics (exact vs. free-text), what limit bounds, or what values domains/concept_kinds accept.

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?

"Resolve concepts" identifies the resource (concepts) but the verb "resolve" is ambiguous for a tool named search_concepts — it does not make clear whether this is a free-text search, canonical-name lookup, or disambiguation step. No sibling is named or implicitly contrasted, so the distinction from get_concept or find_relationships must be inferred.

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?

There is no statement of when to call this versus get_concept (direct lookup) or search_papers. The only usage-adjacent content is a note about how the filters are derived, which is a data-provenance remark, not a selection rule.

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