Recent activity timeline

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

With no annotations, the description carries the full burden of disclosing behavioral traits. It implies the tool is read-only (a timeline), but does not explicitly state it is non-destructive. It also omits details like ordering (presumably chronological), pagination, or whether the timeline is real-time. The phrase 'Recent timeline' suggests a limit, but the limit parameter is not mentioned in the description.

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 a single sentence of 14 words, efficiently conveying the core purpose. It is front-loaded with the key idea ('Recent timeline of what both agents have done'). Every word adds value, though the list of activity types could be slightly trimmed or omitted if the schema already structured them. Overall, it is concise without sacrificing clarity.

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 is simple (one optional parameter, no output schema, no annotations), the description is minimally adequate. It tells what the tool returns (a timeline of specific activities) but does not specify the return format, ordering, or how to use the 'limit' parameter. For a tool with no output schema, more detail on the structure of the returned timeline would improve completeness.

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?

The input schema has one parameter 'limit' (integer) with no description (0% schema coverage). The description does not mention 'limit' or explain its purpose (e.g., 'maximum number of events to return'). While the parameter name is intuitive, the description adds no value beyond what the schema provides, failing to compensate for the missing schema documentation.

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 clearly states the tool returns a 'Recent timeline of what both agents have done' and lists specific activity types (delegations, claims, releases, notes, status changes). It distinguishes from siblings like 'board_list' (board posts) and 'notes_read' (notes only) by implying a combined view. However, it lacks an explicit verb like 'List' or 'View', which slightly reduces precision.

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 use this tool versus alternatives. For example, it does not mention that for agent-specific task status you should use 'ag_task_status', or for board posts use 'board_list'. The description lists included activities but provides no exclusion criteria or context for choice.

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