Input Schema

Name	Required	Description	Default
`fields`	No	Compact mode: comma-separated dotted paths to keep, relative to `data`, e.g. "planets.name,planets.longitude,houses.cusp". Omit for the whole response.
`precision`	No	Compact mode: round fractional numbers to this many decimals. Longitudes carry 14 by default; 2 is finer than any chart is drawn.

TDQS

A3.5/5.0

Behavior3/5

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

Annotations already establish readOnly=true, idempotent=true, destructive=false, so safety is covered. The description adds the endpoint path and a cost signal, but the cost signal is self-contradictory ('Free (0 credits)' followed by 'see your plan — endpoint not in the public credit manifest'), which muddies rather than clarifies the one behavior it tries to add.

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?

The core sentence is front-loaded and wastes no words; the bracketed metadata block is compact and scannable. The only inefficiency is the duplicated and conflicting cost statements.

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?

This is a simple, parameter-light, read-only listing tool with an output schema, so the description need not explain return values. Between the description and the schema an agent has enough to call it correctly; the unresolved cost ambiguity is the main residual gap.

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% and both optional parameters (fields, precision) carry detailed schema documentation including examples. The description adds no parameter meaning of its own, so the baseline 3 applies.

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 names a specific verb and resource — 'List the 21 supported language codes + names' — which tells an agent exactly what comes back and even the cardinality. It is distinguishable from siblings such as translate_glossary_lang or translate_astro, though it never explicitly contrasts with them.

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?

Usage is only implied: an agent can infer this is a discovery/preflight call to fetch valid language codes before invoking the translate_* endpoints, but nothing states that. There are no explicit when-to-use, when-not-to-use, or alternative-tool pointers.

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