Retrieve activities authored by a specific person, filtered by keyword and date range.

Instructions

Activities authored by a specific person, optionally narrowed by a keyword query and date range. Pass identity_id if you have one (from list_identities/resolve_person); otherwise pass name_or_email and the tool resolves it.

Behavior3/5

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

No annotations exist, so the description carries full burden. It reveals the resolution behavior for name_or_email but does not discuss performance, pagination, error handling, or the nature of the response. Adequate but lacks depth.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two sentences with no wasted words. The core purpose is front-loaded, followed by parameter resolution guidance. Perfectly concise.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a 7-param tool with no output schema and many siblings, the description covers the main idea but misses details on date range format, source usage, and result structure. Leaves some uncertainty for complex queries.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 57% (4 of 7 params described). The description adds meaning for identity_id and name_or_email (resolution advice) but does not explain start, end, or source parameters. Falls short of full compensation.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool returns 'Activities authored by a specific person', using a specific verb and resource. It distinguishes from siblings like search_activities and resolve_person by focusing on person-scoped activity retrieval.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Provides clear guidance on when to use identity_id vs name_or_email, and references list_identities/resolve_person. Does not explicitly exclude alternative tools or scenarios, but the context is sufficient for basic usage.

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