B3.2/5.0

Behavior3/5

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

No annotations are provided, so the description carries the full disclosure burden. It usefully reveals the auth/payment model ('paid', '$0.003 per call', x402/MPP) which an agent needs before invoking, but says nothing about determinism, edge cases (zero/negative bytes), or the return format beyond the one-line summary.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness2/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Only one sentence describes the actual operation; the rest is marketplace metadata (origin URL, hostname, brand, provider aliases, family key, endpoint, four keyword lines, price). It is bloated and front-loads provenance and pricing ahead of the functional behavior.

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

Completeness3/5

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

For a one-parameter, no-output-schema utility the description covers the basic contract and adds payment context, so it is close to adequate. The notable gap is byte/unit semantics (decimal MB vs binary MiB, rounding), which is exactly the ambiguity a formatter must resolve.

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?

The single 'bytes' parameter has 0% schema description coverage, so the description must compensate. The example '1048576 bytes as 1 MB' and the mention of 'mebibytes' faintly hint at decimal-vs-binary unit behavior, but the description never documents the accepted input format or the choice between MB and MiB.

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?

The core sentence 'Format a byte count as a human-readable size' states a specific verb and resource, and the Source description restates it consistently. It is clear what the tool does, though the definition offers no differentiation from the many other text/number formatting siblings in the list.

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?

Three concrete use-case lines ('format 1048576 bytes as 1 MB', 'render a file size for a UI', 'convert a byte count into kilobytes and mebibytes') imply when the tool applies. However, there is no explicit when-not guidance and no routing to any of the ~30 sibling tools that overlap in the text-formatting family.

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