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

Without annotations, the description carries the burden of behavioral disclosure. It explains what the tool analyzes (gaps, inter-frame data) but does not specify if the tool modifies files, requires permissions, or has side effects. It also omits behavior for invalid files or 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.

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

The description is concise, consisting of two clear sentences. The first sentence front-loads the primary purpose, and the second adds specifics. No extraneous information, though it could be better structured with bullet points for clarity.

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?

The description covers the analysis scope but lacks output details (e.g., whether results are boolean, metrics, or raw data). Given no output schema and one parameter, more context on expected output would improve completeness.

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?

The schema specifies 'file_path' with a description. The tool description adds no additional parameter-level details beyond what the schema provides. With 100% schema description coverage, the baseline of 3 is appropriate.

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?

The description clearly identifies the tool's purpose as detecting bit reservoir and padding manipulation in MP3 files. It specifies the exact analysis performed (gaps before first frame, inter-frame gaps, data inserted between/around frames), distinguishing it from sibling tools like mp3_detect (general detection) and mp3_frame_analysis (frame-level details).

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?

The description provides no guidance on when to use this tool versus alternatives. It does not mention prerequisites, file types, or scenarios where this tool is preferred over other MP3 analysis tools in the sibling list.

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