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

With no annotations, the description carries the burden of behavioral disclosure. It usefully states the workflow: compose, edit by line or JSON path, attach files, and send to any target. However, it does not disclose side effects, irreversibility of sends, lifecycle/destruction of scratchpads, auth requirements, or error behavior, so important behavioral context is left to the schema.

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?

Three tightly packed sentences: purpose, workflow, and a functional exclusion. Every sentence earns its place, the main payload is front-loaded, and there is no fluff or repetition that wastes an agent's context window.

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?

For a 19-parameter tool with 17 operations and no output schema, the description supplies a clear mental model that the schema cannot provide, and the schema supplies the per-operation and per-parameter detail. The main gap is that the generic 'service tool' alternative is not mapped to a concrete sibling, and import/copy/list/discard aspects are only discoverable from the schema.

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 100%, so the schema already documents all 19 parameters. The description adds a useful high-level grouping (line editing, JSON path, attachment, delivery) but does not add syntactic or semantic detail beyond what the parameter descriptions already provide; baseline 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 as composing, editing, and delivering multi-line text content, and ties it to a distinct scratchpad workflow (edit by line/JSON path, attach, send). It does not explicitly differentiate among the named sibling tools beyond pointing to a generic 'service tool', so it misses the strongest sibling-differentiation credit.

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?

It gives an explicit when-to-use signal ('any multi-line content: emails, documents, descriptions') and an explicit when-not-to-use signal ('short one-liners... use the service tool directly'). The alternative is named only generically, not tied to a specific sibling, which is a partial gap.

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