summarize_time

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

No annotations provided, so the description must convey behavior. It states 'fetch all work logs,' indicating a read-only operation, but does not disclose potential side effects, rate limits, or pagination behavior. Minimal but accurate.

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 single-sentence description is concise and front-loaded with the core action, containing no redundant words. It efficiently communicates the tool's purpose.

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 simple tool (2 optional params, no nested objects, no output schema), the description suffices by specifying the grouping by Jira issue. A minor gap is the lack of detail on the output format (e.g., fields returned), but overall adequate.

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 coverage is 100% with clear descriptions for both parameters. The description restates 'optional assignee/issue filter' without adding new syntax or constraints beyond the schema, meeting the baseline for full coverage.

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 it fetches work logs and summarizes total time grouped by Jira issue, with optional filters. The verb 'summarize' and resource 'total time' distinguish it from sibling tools like list_worklogs or get_worklog.

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 usage for aggregated time reporting with optional filters, but provides no explicit guidance on when to use this over alternatives like list_worklogs or log_time. Missing 'when not to use' or comparison phrases.

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