generate_watch_digest

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

With no annotations, the description carries the full behavioral burden. It adds one useful nuance — entries are included if 'checked or dated' since the date — but does not disclose whether the call has side effects (read-only vs generating/storing output), the output shape, or how the summary is computed.

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 word contributes. It is appropriately sized for a two-parameter tool, though slightly under-specified rather than merely concise.

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 annotations and no output schema, the description omits critical context: whether this is a safe read operation, what the returned digest looks like, and how it relates to list_watch_items. For a tool with two optional params and five siblings, these gaps are material.

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%, so the description must explain both parameters. It clarifies 'since' as a YYYY-MM-DD date filter, but 'limit' is never mentioned and remains semantically undefined.

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 states a specific verb ('Summarize') and resource ('tracker entries') with a clear date-scoped filter ('since a YYYY-MM-DD date'). It is distinguishable from siblings whose verbs differ (list, find, suggest, propose, apply), though 'summarize' leaves unspecified what the digest actually contains.

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 is given on when to choose this tool over list_watch_items or other siblings. The date filter weakly implies a use case (recent summaries), but no alternatives, exclusions, or contextual triggers are mentioned.

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