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

With no annotations, the description carries the full burden and delivers: it explains the differing effects on pending vs AI-linked/accepted suggestions (dismissed vs unlinked), that the AI will not re-suggest, and that ownership of the tracker is required. It lacks detail on reversibility of the unlink or any permission/rate-limit notes, but covers the essential side effects.

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?

Four tight sentences, front-loaded with the core action and effect, then the id source and return value. No filler or redundancy.

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 2-param mutation tool with no annotations and no output schema, the description supplies the behavioral effects, the input provenance, and the single return value (resolvedCount). Only minor gaps remain around error/permission behavior and edge cases, so it is nearly complete.

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%, so baseline is a 3; the description goes beyond the schema by narrowing which suggestions to pass ('pending or aiMatched') and reaffirming the trackerId ownership constraint, adding genuine semantic value even though the source tool is already in the schema description.

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 ('Reject') and resource ('smart-tracking suggestions of a tracker the user owns'), which immediately distinguishes it from the sibling accept_tracker_suggestions. An agent can tell what the tool does without opening the schema.

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?

Tells the agent where the required input comes from ('Suggestion ids come from list_tracker_suggestions (pending or aiMatched)'), giving clear context for invocation. It does not explicitly name accept_tracker_suggestions as the contrasting alternative or state when-not to use it, so it stops short of full when/when-not guidance.

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