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

Description states the core behavior (removes whitespace) and is consistent with expected non-destructive transformation. No annotations provided, but description covers main behavioral aspect. Lacks details on error handling for invalid JSON.

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?

Two sentences, zero wasted words. Front-loaded with purpose, immediately followed by usage guideline.

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?

For a simple one-parameter tool with no output schema, the description covers purpose, usage, and parameter semantics adequately. Minor gap: no mention of input validation or error behavior, but acceptable given simplicity.

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?

With 0% schema coverage, the description adds meaning by specifying that 'text' is a JSON string and that the tool removes whitespace, clarifying the parameter's role beyond the bare schema.

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?

Clearly states the verb 'Minify' and resource 'JSON', with parenthetical explanation 'remove whitespace'. Distinguishes from sibling tools like json_format which beautify JSON.

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?

Provides explicit usage context: 'Minify JSON for compact payloads or size checks'. Implies when not to use (e.g., when readability is needed), though alternatives not named explicitly.

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