transfer_status

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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, so 'Makes no remote requests' largely restates the annotation rather than adding new information. The one genuinely additive detail is that progress is persisted local state, which tells the agent results may be stale relative to remote reality; beyond that there is no disclosure of output shape or failure modes.

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 short sentences with zero filler; the primary purpose is front-loaded and the secondary behavioral note follows. Nothing needs trimming.

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 output schema, the description does the right thing by naming what comes back (progress plus the operation and destination for resuming). The only real hole is the undocumented projectId, which for a one-parameter read tool is a modest gap.

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% and the single required projectId parameter carries no description in either the schema or the tool description. The description should have clarified which project's transfer record is read (e.g. the source or destination project), but it says nothing, leaving the caller to guess.

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 (read) and resource (persisted transfer progress) plus what the payload contains: the operation and destination needed to resume. That is far more than a restatement of the name, but it never contrasts itself with the adjacent transfer_recover sibling, so an agent must infer the split.

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 phrase 'needed to resume after interruption' implies the situation that calls for this tool, but there is no explicit when-to-use versus transfer_recover/transfer_status-style alternative, no stated prerequisites, and no exclusion of cases where a fresh transfer should be started instead.

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