tracker_update

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

With no annotations supplied, the description carries the full burden and does not say whether this is a partial patch or a full overwrite. This matters concretely because notes/status/contact default to empty strings, so an agent cannot tell from the description whether omitting a field clears it. Error behavior for an unknown id and the response shape are also unstated.

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 the resource and identifier up front and zero filler. It is efficient, though the brevity comes at the cost of the semantics noted elsewhere rather than being genuinely complete.

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 small 4-parameter mutation tool, an agent can probably form a call, but with no annotations, no output schema, and zero schema coverage, the definition should explain overwrite semantics and status value expectations. The most consequential behavioral question for this tool is left unanswered.

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 0% and the schema only provides bare titles, so the description must compensate — but it merely restates the parameter names already visible in the schema. It adds no valid status values, no contact format, no notes length/format, and no id provenance (where to obtain it, e.g. from tracker_list).

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 ('Update a tracker entry') plus the fields affected ('status/notes/contact by id'). It is implicitly distinguishable from tracker_add and tracker_list, though it never names those siblings to confirm the boundary.

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 use this instead of tracker_add or tracker_list, no preconditions, and no note that the entry must already exist. The only cue is the verb 'update', leaving the agent to infer everything.

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