Read-onlyIdempotent

Per-solution search against the ps (Planetary Systems) table -- one row per published parameter SOLUTION, with several solutions per confirmed planet. Good for comparing how a planet's measured parameters changed across papers; NOT a planet count or a clean per-planet list (its row count is parameter solutions, not planets). For planet counts or one-row-per-planet listings use composite or confirmed_planet_count instead.

A4.3/5.0

Behavior4/5

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

Annotations already declare readOnlyHint, idempotentHint and destructiveHint=false, so the safety profile is covered. The description contributes genuinely non-obvious behavioral context: the row cardinality is parameter solutions, not planets, which would otherwise cause miscounts. It omits return shape/pagination behavior, but the output schema exists, so this is a minor gap.

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

Conciseness4/5

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

Front-loaded with the core verb and table, then the caveat and alternatives. It is a single dense sentence with parenthetical asides; every clause earns its place, though the double-em-dash structure is slightly harder to scan than a couple of short sentences.

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

Completeness4/5

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

With read-only annotations and a present output schema, the description only needed to convey grain and routing, which it does well. The one remaining ambiguity an agent might face — which column names are valid in `query` — is only partially mitigated by the schema examples.

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?

Schema description coverage is 100%, so `limit` (1-10000, default 25) and `query` (optional WHERE clause) are already documented, and the schema examples show syntax like `pl_massj > 5.0`. The description adds no further parameter detail beyond implying solution-level querying, so the baseline 3 applies.

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

Purpose5/5

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

States a specific verb and resource ("per-solution search against the `ps` (Planetary Systems) table") and defines the grain of the results ("one row per published parameter SOLUTION"). It explicitly distinguishes itself from `composite` and `confirmed_planet_count`, so an agent can pick correctly without opening schemas.

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

Usage Guidelines5/5

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

Gives an explicit positive use case ("Good for comparing how a planet's measured parameters changed across papers") and explicit exclusions ("NOT a planet count or a clean per-planet list"), then names the two sibling tools to use instead. Both when-to-use and when-not-to-use are covered.

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