get_spec

Fetch authoritative Tank Fight game parameters and rules as JSON. Retrieve exact specs for screen size, tank stats, bullet behavior, walls, controls, and AI before implementing features.

Instructions

Return one section of the Tank Fight specification as JSON.

Use this to get the authoritative numbers and rules before implementing a feature — screen size, tank and bullet stats, wall layout, controls, AI parameters, and so on. Do not infer these values from an existing implementation and do not invent them; this file is what the implementations are supposed to agree with.

Args: section: A section name from list_sections, or a dotted path to go straight to a value, e.g. "entities.bullet" or "ai.enemy.turn_chance_per_tick".

Tool call template

Replace each placeholder with a value matching the input schema. Only required parameters are included; add optional parameters as needed.

A4.6/5.0
Behavior4/5

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

With no annotations, the description carries the full burden of behavioral disclosure. It adds crucial context: the spec is authoritative, and it explicitly warns against inferring values from existing implementations. However, it does not mention error handling or behavior for invalid section names, so it's not fully transparent on edge cases.

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?

The description is compact and front-loaded, with a clear one-sentence summary followed by usage guidance and a well-formatted Args section. Every sentence adds value, and the formatting makes it easy to scan.

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?

For a simple single-parameter tool with an output schema, the description is complete: it explains the purpose, parameter format, and authoritative nature of the data. It appropriately references list_sections for valid section names and provides examples of dotted paths. No additional return-value details are needed given the output schema.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters5/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema only declares 'section' as a string with no description, so the description provides all parameter semantics. It explains that the value can be a section name from list_sections or a dotted path, with concrete examples like 'entities.bullet'. This is essential information not available from the schema alone.

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?

The description opens with 'Return one section of the Tank Fight specification as JSON,' which is a specific verb+resource statement. It also explains the use case ('before implementing a feature') and distinguishes itself from sibling tools by focusing on retrieving a named section of the specification.

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

Usage Guidelines4/5

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

It clearly states when to use the tool ('before implementing a feature') and warns against inferring or inventing values, which provides strong context. However, it does not explicitly name alternative tools or exclusions beyond referencing list_sections for section names, so it stops short of the explicit alternative guidance found in a 5.

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