list_unsourced_facts

Read-only

Find events missing citations or tagged UNSOURCED so you can source every fact. Returns each unsourced event with person, type, date, and reason.

Instructions

Audit: list events that lack a citation or are tagged UNSOURCED.

This is the core quality query for a fully-cited tree -- run it to find facts that still need a source. Returns each offending event with its person, type, date, and the reason ('no-citation' or 'tagged-unsourced').

Tool call template

  }
}

personNoOptional: restrict to one person (handle/gramps_id).
include_privateNoShow living people and private records in full. Only when the user asks for them; they are withheld by default.

A4.3/5.0
Behavior4/5

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

Annotations already cover the safety profile (readOnlyHint=true, openWorldHint=false), and the description goes beyond them by specifying the return shape: each offending event with its person, type, date, and the reason value ('no-citation' or 'tagged-unsourced'). It does not discuss pagination or volume limits.

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?

Three short sentences, front-loaded with the identifying verb+resource, then when-to-use, then return contents. No sentence is redundant.

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

Completeness5/5

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

With no output schema, the description carries the burden of describing what comes back, and it does so concretely (person, type, date, reason). Combined with annotations and full schema coverage, an agent has everything needed to call it correctly.

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 description coverage is 100%, so both parameters (person, include_private) are already fully documented in the schema. The description adds nothing about parameter syntax, so the baseline of 3 applies.

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?

States a specific verb and resource ('list events that lack a citation or are tagged UNSOURCED') with the audit framing up front. An agent can distinguish it from adjacent read tools like get_facts or verify_tree without opening the schema.

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?

Explicitly frames when to run it ('the core quality query for a fully-cited tree -- run it to find facts that still need a source'). It gives clear context but never names a contrasting sibling tool or states when not to use it.

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