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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description adds a genuine nuance — that coverage and check counts are frozen values stored at save time rather than live computations. It omits ordering, volume, and empty-result behavior for a list operation.

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?

One compact sentence, front-loaded with the resource and followed by the returned-content qualifier. No filler, though it is a noun phrase without a leading verb, which slightly weakens the action framing.

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 carries the burden of explaining return values and does so only partially — coverage and check counts are named, but draft identity fields (name, id, timestamp) that an agent would need to chain into compare_metadata_draft are not mentioned. Adequate for a simple read, but leaves the agent guessing at the record shape.

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 coverage is 100% with a single required application_id, so baseline is 3. The phrase 'tracked application' adds a mild semantic constraint (the id must belong to a tracked app), but nothing about format or failure behavior for unknown ids.

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 the resource precisely (saved metadata drafts for a tracked application) and even names the payload content (coverage and check counts at save time). It is distinguishable from save_metadata_draft and compare_metadata_draft by the 'saved drafts' framing, though it never explicitly contrasts itself with those siblings or uses an explicit verb like 'lists'.

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?

No guidance on when to call this versus compare_metadata_draft, get_metadata, or save_metadata_draft. The need to have an application_id scopes it implicitly to a tracked app, but usage conditions and exclusions are entirely absent.

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