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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the safety profile is covered. The description adds useful behavioral context beyond that: the 24-hour window, Monday look-back to Friday, and exclusion of parked/cancelled work. It does not cover auth requirements or rate limits, but for a read-only reporting tool this is reasonably transparent.

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?

The description is front-loaded with the tool's purpose and immediately enumerates the standup sections. It packs useful constraints and scope semantics into a compact paragraph without wasting sentences. The API reference is appropriately placed at the end.

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?

Even without an output schema, the description enumerates the standup contents (done, plan, blockers, overdue/stalled), so an agent knows what to expect. It also covers scope behavior, timing, and exclusions. This is sufficient for correct invocation of a read-only reporting 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?

Schema description coverage is 100%, so the baseline would be 3. The description goes further by defining what 'me' and 'client' mean semantically — work assigned to or owned by you versus the whole client team — which is not fully captured by the enum labels alone.

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 exactly what the tool produces: a daily standup covering done-since-last-standup, today's plan, blockers/open questions, and overdue/stalled items. It is specific enough to distinguish from generic task-list siblings like list_my_tasks or get_task, because it describes a synthesized report rather than raw task retrieval.

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?

It gives clear timing guidance — 'Run it at the start of your day' — and explains scope selection: 'me' for personal work, 'client' for the whole client team. It also states exclusions (parked and cancelled work). It does not name alternative tools, but no close sibling appears to serve the same daily-summary purpose.

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