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

Explicitly states 'Read-only', which is the key behavioral trait. Annotations are absent, so the description carries full burden. No mention of auth or rate limits, but for a simple read operation the disclosure is adequate.

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 sentences, no waste. The first sentence conveys purpose and scope; the second adds behavioral and usage context. Efficiently front-loaded.

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?

Given the tool's simplicity (2 optional params, no output schema), the description covers purpose, behavior, and usage. No gaps remain; it is fully complete for its complexity.

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 both parameters (hours, projectId) described. The description adds 'recent time window' which aligns with hours, but does not significantly enhance understanding beyond the schema. Baseline 3 is appropriate.

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?

Clearly states the tool returns a summary of recent activity (tasks created, closed, updated) over a time window. The verb 'Return a summary' and the specific resource 'recent activity' are explicit. It distinguishes well from sibling tools which focus on individual CRUD operations.

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?

Describes the tool as handy for standups and reviews, giving clear usage context. Does not explicitly state when not to use or provide alternatives, but the purpose is sufficiently distinct among siblings.

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