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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint, so the safety profile is fully covered. The description adds only the words 'currently' and 'watches' — it says nothing about result volume, ordering, recency window, or whether 'near' includes fuzzy/phonetic matches, which is exactly the kind of context an annotation cannot supply.

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 padding or repetition of the title, which is appropriate for a no-argument query tool. It is efficient, though the brevity shades into under-specification rather than genuine conciseness.

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 zero-param, no-output-schema tool the description is the only source of semantics, and the one ambiguous term ('near') is left unexplained. The agent cannot predict what constitutes a match or how results are scoped, which is the central unknown for this tool.

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, and the schema has 100% description coverage, so there is nothing for the description to compensate for. Baseline of 4 applies; the description cannot add parameter meaning that does not exist.

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 phrase 'Everything currently near the names this user watches' gestures at retrieving conflicts for watched marks, but the operative word 'near' is never defined (similarity? phonetic? class overlap?) and there is no verb telling the agent what operation this is. It does scope the result to the user's watches, which separates it somewhat from sibling tools like filing_landscape, but it does not distinguish itself from my_watches or dismiss_conflict.

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 when-to-use guidance, no stated prerequisite (e.g., that watches must exist), and no reference to adjacent siblings such as my_watches (manage watches) or dismiss_conflict (act on a conflict returned here). The agent must infer that this is the read-side counterpart to dismiss_conflict entirely on its own.

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