bitrix_get_timesheet_summary

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

With no annotations, the description carries the full burden and does well: it declares read-only behavior, required access scopes, and notes that the timeman part only applies when userIds are specified. This meaningfully discloses auth needs and conditional behavior beyond the schema.

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 dense but efficient: it front-loads the read-only nature, states the aggregation structure, lists optional filters, and closes with the authorization nuance. Every clause earns its place without redundancy.

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 read-only summary tool with no output schema, the description conveys the output shape (hours by user and by task), the period semantics, optional filters, and permission needs. It is slightly incomplete only in not clarifying behavior when no data matches or how it relates to the overlapping worktime-report sibling.

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 the parameters are already well documented and the description adds little beyond restating the filtering intent. The baseline of 3 applies because the schema does the heavy lifting.

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 identifies a read-only summary of work-time tracking, with hours aggregated by users and tasks over a date range. It names the resource and scope, but does not explicitly distinguish it from the sibling bitrix_get_worktime_report, so it falls short of full sibling differentiation.

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 provides practical usage context: date range, optional user/project filtering, and the access-scope requirement. However, it does not state when to prefer this tool over bitrix_get_worktime_report or mention any exclusion criteria, leaving the choice between similar tools implicit.

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