TDQS

A3.6/5.0
Behavior4/5

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

Annotations already declare readOnly, idempotent, openWorld and non-destructive, so the safety profile is covered. The description adds a genuinely non-structured behavioral trait: the tool costs $0.025 USDC via x402, which an agent must know before invoking. It stops short of describing return shape or rate limits.

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?

A single sentence that front-loads the inspection targets and tucks the payment detail into a parenthetical. No filler sentences, nothing that fails to earn its place.

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?

For a one-parameter, read-only tool the description plus annotations cover invocation adequately, and the enumerated inspection targets (headings, interactive counts, link tree) partly preview the return payload in the absence of an output schema. Missing details on pagination, size limits, or failure modes keep it from a 5.

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% for the single url parameter, so the schema already carries the meaning. The description adds nothing about URL format, accessibility requirements, or behavior for non-public URLs, so 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?

Names a specific verb (Inspect) and concrete resources (headings, interactive counts, link tree), which is far more informative than the title alone. It does not explicitly contrast itself with siblings like morsebyte_content_digest or morsebyte_verify_links, which overlap in the page-inspection space.

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 when-to-use statement, no prerequisites, and no mention of when an agent should prefer morsebyte_verify_links or morsebyte_content_digest instead. Usage can only be inferred from the phrase 'Inspect webpage'.

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