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

With no annotations, the description carries the full burden and does the most important part well: it discloses that deletion is an archive, that scanning and emailing stop, and that stored items remain in Scout history. It omits permissions/auth requirements, whether the watch can be un-archived, and error behavior for a missing id.

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 the effect front-loaded and the data-retention caveat second. Every clause adds information; there is no filler.

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 one-parameter mutation with no output schema, the description covers the essential behavioral outcome and data-retention semantics. It leaves a gap on what happens if watchId is omitted (the schema marks it non-required) or refers to a nonexistent watch.

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 100% for the single watchId parameter, so the schema already documents its source ("Watch id from list_watches"). The description adds no further meaning about the parameter, which is the expected baseline when the schema is complete.

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 and resource ("Remove a watch") and immediately defines what removal means operationally: archived, no further scans or emails. It is clearly distinct from add_watch/update_watch by plain reading, but it never names or contrasts a sibling explicitly.

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 or when-not-to-use guidance. An agent must infer that this replaces pausing or updating a watch, and nothing says whether removal is recoverable or when to prefer update_watch. The consequence clause ("no further scans or emails") hints at intent but is not guidance.

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