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

Annotations already declare readOnly, idempotent, non-destructive, so the safety profile is covered. The description adds real content-level disclosure: no secrets are included, and library files are referenced by name rather than copied, plus the README documents what was omitted and why. It stops short of stating cost, size, or whether the archive is delivered synchronously.

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?

Two dense sentences, front-loaded with what the tool produces, followed by the security and access constraints. Every clause carries a distinct fact; nothing is padding.

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?

With no parameters and no output schema, the description carries the load by describing the return artifact in detail (zip, per-table JSON, README of exclusions) and the ownership restriction. An agent has enough to call it correctly and set expectations.

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?

Zero parameters, so the baseline of 4 applies; there is nothing for the description to disambiguate at the argument level.

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 (export) and resource (the whole workspace), then details the artifact: one zip with one JSON file per table plus a README. No sibling offers exporting, so there is no confusion with any other tool 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.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The only guidance is the eligibility gate 'For the owner only.' There is no alternative export/snapshot tool to route against, so no when-not-to-use statement is needed, but the description never says when exporting is appropriate versus reading the workspace state through read_the_workspace_state.

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