summarize_log

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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description adds nothing behavioral beyond that: it does not say where the file is read from, what happens with malformed CSV, how units are applied, or any limits. It essentially restates the operation type the annotations already imply.

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?

A single front-loaded sentence with no filler, and the optional nature of units is stated up front. It is slightly awkward and jargon-heavy ('plain CSV channels') rather than maximally clear, which keeps it short of a 5.

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?

An output schema exists, so return values need not be explained, but with the required 'path' parameter undocumented and 'channels' undefined, the definition leaves real gaps for a two-parameter tool. It also omits any indication of what a 'summary' contains or how the result relates to the siblings.

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?

Schema description coverage is 0%, so the description must carry the parameter burden, but it only partially addresses 'units' ('explicit caller-supplied units') and says nothing about the required 'path' argument (file location, format, expected extension). The units hint that units override inference from the CSV is useful but far from complete.

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?

States a specific verb (summarize) and resource (exported plain CSV channels), so an agent knows it produces a summary of a CSV log. It is clear on its own but does nothing to distinguish it from siblings like capabilities, inspect_tune, or compare_tunes, and terms such as 'channels' are domain jargon left unexplained.

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 gives no when-to-use guidance, no prerequisites, and no mention of the sibling tools it could be confused with. An agent must guess whether this applies to any CSV or only 'exported' one, and what the relationship to inspect_tune/compare_tunes is.

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