get_worktray_member_stats

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

With no annotations, the description fully carries the burden. It discloses that the tool analyzes completed tasks within a lookback window, returns a compact summary with top 20 members, and writes full results to a cache file available via a resource. This provides good transparency about what the tool does and its limitations.

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 concise and well-structured. The first sentence states the purpose, followed by additional details in two short paragraphs. No redundant or unnecessary information, earning top marks.

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 complexity (2 params, no output schema, no annotations), the description covers the tool's behavior adequately. It explains the summary output, member limit, and cache file. However, it could better describe the exact metrics (e.g., what 'queue health' entails), but overall it is sufficiently complete.

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 0%, so the description must add parameter meaning. It hints at the 'days_back' parameter via 'lookback window', but does not explain 'worktray_id' or provide full parameter semantics. The added value is marginal, justifying a score of 3.

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 retrieves per-member workload, performance, and queue health metrics for a worktray. The verb 'Get' and specific resource 'per-member metrics' provide precise purpose, distinguishing it from sibling tools like get_worktray (overall info) or get_employee_stats.

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?

The description implies use for member-level metrics but does not explicitly guide when to use this tool versus alternatives like get_worktray or get_employee_stats. No 'when to use' or 'when not to use' guidance is given, though the context of 'per-member' and 'worktray' is clear.

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