A4.1/5.0

Scored 2026-10-16 19:10 across 2 tools

Disambiguation5/5

The two tools are cleanly separated by cardinality: get_sun_times for a single date and get_sun_times_range for an inclusive span of up to 366 days. The range description even states explicitly when to prefer it over repeated single-day calls, eliminating any risk of misselection.

Naming Consistency5/5

Both names follow a consistent snake_case verb_noun pattern (get_sun_times, get_sun_times_range) with the range variant clearly derived from the base name. No deviation in style, casing, or verb choice.

Tool Count4/5

Two tools is thin by generic standards, but for a narrowly scoped read-only ephemeris service the single-vs-range split is the only meaningful axis, and the count is arguably exactly right. Nothing redundant is included, though a third tool (e.g. location/timezone lookup) would have added utility.

Completeness4/5

The surface covers the domain thoroughly for a lookup service: solar events, all twilight phases, golden/blue hour, azimuths, moonrise/moonset, and moon phase, plus range batching and documented edge cases (polar day/night, skipped calendar days). The only real gap is input assistance such as timezone or coordinate resolution, which agents must supply themselves.

A3.7/5.0

Behavior5/5

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

Beyond the annotations (readOnlyHint=true, openWorldHint=false), the description discloses key behavioral traits: output format (ISO 8601 in local timezone), handling of polar day/night via sun_status, and that non-occurring events are null. This is valuable context for interpreting results.

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 description is front-loaded with the core output list, then adds essential behavioral notes. The first sentence is a long enumeration, but every item is relevant. It is concise and well-structured overall.

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

Completeness5/5

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

Given the tool's complexity, the presence of a full output schema, and annotations that declare safety, the description covers the critical edge cases (polar day/night, null events) and output format. An agent has enough to invoke it correctly.

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 the schema already documents each parameter thoroughly. The description adds no parameter-specific meaning beyond what is in the schema; it only mentions 'any coordinates' and 'any date' generically.

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 what the tool does: it returns a comprehensive set of solar and lunar times for given coordinates and date. It uses specific verbs and resources, but it does not explicitly distinguish itself from the sibling tool get_sun_times_range, which likely handles date ranges.

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

Usage Guidelines2/5

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

The description provides no guidance on when to use this tool versus alternatives. It does not mention the sibling tool or any conditions that would select this tool over another. It only implies usage by stating what it returns.

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

get_sun_times_rangeSunrise & sunset times for a date rangeA

Read-only

Inspect

Same per-day data as get_sun_times but for an inclusive date range (up to 366 days) in a single call. Use this instead of repeated get_sun_times calls when you need several consecutive days. The days array may contain fewer entries than the number of dates requested: calendar days that never existed in that timezone (Samoa skipped 30 December 2011 when it crossed the date line) are left out, so read each entry's date field instead of assuming one per requested date.

Name	Required	Description
`tz`	No	IANA timezone like 'Europe/Madrid'. Omit to use the local timezone of the coordinates, resolved automatically (recommended).
`lat`	Yes	Latitude in decimal degrees.
`lng`	Yes	Longitude in decimal degrees.
`date_end`	Yes	Last day (inclusive), YYYY-MM-DD. The range covers at most 366 days counting both ends, so date_end can be at most 365 days after date_start.
`date_start`	Yes	First day, YYYY-MM-DD.

Output Schema

Name	Required	Description
`lat`	Yes
`lng`	Yes
`days`	Yes	One entry per local day that exists in that timezone, in order; match entries by their date field.
`tzid`	Yes	IANA timezone used.
`attribution`	No

A4.7/5.0

Behavior5/5

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

Annotations already declare readOnlyHint and openWorldHint=false, but the description adds genuinely non-obvious behavior: the days array may be shorter than the requested range because non-existent calendar days (Samoa, 30 Dec 2011) are omitted, and callers must read each entry's date field rather than assuming a 1:1 mapping.

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?

Three sentences, each earning its place: the first establishes scope and the sibling comparison, the second gives the usage rule, the third delivers the critical edge case. The routing rule is front-loaded before the caveat.

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

Completeness5/5

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 no explanation. Combined with full schema coverage and annotations, the description supplies everything an agent needs — including the non-obvious short-array behavior — to call and interpret this tool correctly.

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 all five parameters (tz, lat, lng, date_start, date_end) are already documented, including the 366-day cap. The description restates the inclusive-range and 366-day constraint but adds no syntax or format detail beyond the schema, 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+resource ('Same per-day data as get_sun_times but for an inclusive date range') and immediately scopes it against its only sibling. An agent can distinguish it from get_sun_times without opening either schema.

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 when-to-use rule: 'Use this instead of repeated get_sun_times calls when you need several consecutive days.' The alternative and the selecting condition are both named, leaving nothing to inference.

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