get_colonists_report

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

No annotations are supplied, so the description carries the full burden. It does disclose the payload contents (totals, children, armed/unarmed split, wounded, job assignments), which is genuine behavioral information about what the agent will receive. However, it says nothing about whether the call is read-only, whether it reflects live game state or a cached snapshot, or how large the result may be.

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?

A single sentence, front-loaded with the 'Population overview' framing followed by the field list. Every clause names a distinct data category, so there is little waste. The trailing 'workers assigned to each job' slightly overlaps with 'job distribution', a minor redundancy.

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?

With no output schema and no annotations, the description is the only source of information about the return value, and it enumerates the returned fields thoroughly enough for an agent to decide relevance. What is missing is the shape/format of the response and whether values are current, but for a zero-parameter report tool this is close to sufficient.

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?

The tool takes zero parameters, so there is no parameter semantics to explain and the baseline of 4 applies. The description correctly avoids inventing filters or options that the empty schema does not support.

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?

The description names the resource (colonists) and enumerates the specific contents of the report: totals, children, job distribution, armed/unarmed adults, wounded count, and per-job worker assignments. That enumeration distinguishes it from siblings like get_animal_report or get_economy without needing to name them. It falls short of 5 only because it never explicitly frames the verb as a read-only retrieval or contrasts it with any alternative.

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 the many other report tools (get_daily_report, get_animal_report, get_economy), and no prerequisites or exclusions. Usage is only inferable from the word 'overview'. An agent must guess whether this is the right report for a given question.

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