  3. First observed

TDQS

A4.1/5.0
Behavior4/5

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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description adds value beyond that by disclosing provenance ('first-party sourced', 'dated') and the default-vs-full response behavior, which the agent cannot infer from annotations alone. It omits any caveats about freshness limits or rate limits, keeping it short of a 5.

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?

Two sentences, front-loaded with what the tool returns before the detail-level switch. Every clause carries content, though the middle run-on listing of fact categories is dense and slightly harder to parse than necessary.

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

Completeness4/5

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

With an output schema present, return values need not be explained, and both parameters plus their enums are documented. The description covers scope, provenance and the default behavior, leaving only cross-tool routing guidance as a gap for what appears to be a low-risk read-only tool.

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

Parameters4/5

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

Schema coverage is 100%, so the baseline is 3 and the schema already defines both enum parameters. The description goes beyond the schema by specifying what 'full' actually unlocks (methodology, migration notes, limitations, complete source registry) and by noting the compact default, which meaningfully clarifies the cost/benefit of the flag.

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 names a specific resource (Grabbit's pricing) and enumerates exactly what the response contains: dated, first-party sourced comparisons against Urlbox, ScreenshotOne and ApiFlash, plus named plan math and separate API/SDK/CLI/MCP/auth facts. An agent can immediately distinguish this from sibling tools get_grab, get_usage, grab and list_grabs, which deal with grab records and usage rather than pricing.

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

Usage Guidelines3/5

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

It gives real guidance on the detail parameter (compact by default, request full for methodology/migration/limitations/source registry), but never states when to reach for this tool versus alternatives or any exclusions. Usage is only implied by the topic.

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