sync_status

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

Annotations already declare readOnlyHint=true and openWorldHint=false, so the safety profile is covered. The description adds useful behavioral content by stating that it reports progress of background detail fetches (implying asynchronous state) and cache counts, but it says nothing about refresh behavior, polling cadence, or what an in-progress vs. idle state looks like.

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; every clause enumerates a distinct piece of returned information. It is efficiently sized for a no-argument status tool, though it stops just short of fully exploiting its brevity.

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 and no parameters, the description is the only source of information about what comes back, and it lists the reported categories but not their shape, units, or how to interpret progress values. Adequate for a simple status read, but an agent cannot tell from this alone what a returned record looks like.

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?

The tool takes zero parameters, so the schema imposes no semantic burden and the baseline of 4 applies. Nothing in the description is needed to disambiguate arguments.

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 names the specific resource it reports on — sync times, cache counts, and background detail-fetch progress — which is distinct from sibling action tools like sync_collection and sync_release_details. It lacks an explicit verb, but 'sync_status' plus the enumerated contents make the purpose unambiguous.

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?

There is no guidance on when to call this versus the sync_* tools that actually trigger syncing, nor any stated precondition (e.g., check before starting a sync to avoid redundant work). The agent must infer that this is the read-only status companion to sync_collection and sync_release_details.

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