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

Annotations already declare this is a readOnly, idempotent, non-destructive, closed-world list operation, so the safety profile is covered. The description adds the notion of periodicity/status-report semantics, but says nothing beyond schema about pagination behavior or result shape. Adequate but not rich.

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 tight sentences with zero waste; the core purpose is front-loaded and the filter dimensions follow immediately. Every clause earns its place.

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?

Annotations carry the safety profile and the schema fully documents all six parameters, so the description needn't repeat them. For a simple filtered-list tool with no output schema, only a hint on pagination or result contents would meaningfully improve it.

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%, with per-parameter descriptions including the 'resolve via list_projects' hint, so the baseline is 3. The description only restates the filter dimensions (project, timeframe, year) already documented in the schema, adding no syntax or format detail.

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 clear verb (List) and resource (project updates), and even disambiguates the domain term by clarifying these are 'periodic project updates (status reports)'. It does not explicitly differentiate itself from the close sibling get_project_update or list_projects, which keeps it just shy of a 5.

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?

'Filter by project, timeframe, or year' implies the retrieval scenarios but never states when to use this versus get_project_update (single fetch) or other project sub-resource listers. No exclusions or alternatives are offered, leaving usage to inference.

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