List project updates

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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is fully covered by structured data. The description adds the 'periodic/status report' semantic framing of the resource, which is modestly useful, but says nothing about pagination behavior, sorting, or result volume beyond what the schema states.

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 short sentences, front-loaded with the core action and followed by the filtering capability. No redundant or filler text; 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?

For a simple list tool with no output schema, the safety annotations and full schema coverage carry most of the burden. The description is minimally adequate but omits any sibling disambiguation (list_projects, get_project_update) and any note on result scope, which would help an agent pick correctly among the many list_* tools.

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 all six parameters are documented in the schema itself. The description's mention of 'project, timeframe, or year' loosely maps to project_id, timeframe, and period_year but adds no syntax or default detail beyond the schema, so the baseline 3 applies.

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 (List) and resource (project updates) and clarifies with '(status reports)', which disambiguates the resource's meaning. However, it does not distinguish this tool from siblings like get_project_update or list_projects, so the agent must infer from context that this is the batch read path.

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 usage (retrieval with optional filters) but gives no explicit when-to-use, when-not-to-use, or alternatives. It does not, for example, contrast itself with get_project_update for fetching a single record.

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