Input Schema

Name	Required	Description
`body`	Yes	Wrapper { natal: ChartInput } used by endpoints that take a base natal plus extra parameters in flat fields.
`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.

Output Schema

Name	Required	Description	Default
`meta`	No
`mcShift`	No
`mundaneAspects`	No

B3.2/5.0

Behavior3/5

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

Annotations already declare readOnly, idempotent, non-destructive, and closed-world, so the description is only responsible for extra context. It contributes the 100-credit Tier 4 cost and the POST endpoint, which is genuinely useful for budget-aware planning, but says nothing about how expensive the call is in latency or what happens when targetDate is omitted or malformed.

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?

A single functional sentence followed by three bracketed metadata lines; nothing is padded and the purpose is front-loaded. The metadata lines are terse and useful rather than noise, though 'Astro-Geography' as a group label adds little.

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

Completeness3/5

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

With an output schema present and full schema description coverage, the definition doesn't need to explain return values, and the annotations cover safety. What remains missing is orientation within a large geo/ACG family of siblings and any note on how progressed CCG output differs from the natal ACG tools, which matters for a 100-credit call.

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 the nested natal object is heavily annotated (timezone, houseSystem, ayanamsa, precision, fields), so the schema does the heavy lifting. The description adds no meaning about orb, point, latitude, targetTime, targetTzOffset, or fastPlanetsOnly, leaving those to the schema as well; 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 gives a specific verb (Analyse) and a specific resource (Cyclo-Carto-Graphy lines), then names the concrete artifacts produced: progressed A*C*G lines at a target date, mundane/local aspects, and latitude crossings. It implicitly distinguishes itself from the natal ACG siblings via 'progressed', but never names astroway_geo_acg or astroway_geo_solar_acg explicitly, so the boundary is left to inference.

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?

There is no statement of when to choose this tool over astroway_geo_acg, astroway_geo_acg_line_report, or astroway_geo_solar_acg, and no prerequisites or exclusions. The only usage signal is the endpoint and price metadata, which tells an agent nothing about selection.

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