correct_person_claim

Idempotent

Save an explicit user correction, rejection or retraction of a cited person claim, preserving its ID and revision history. Read its current revision first.

Input Schema

NameRequiredDescriptionDefault
valueNo
actionYes
reasonYesThe user's correction or explanation; never invent a correction on their behalf.
team_idNoOwning Team for Team knowledge; omit for personal knowledge.
claim_idYesCanonical claim ID returned by a knowledge section or memory_get.
validityNoOptional correction to the claim validity dates; retain the precision the user supplied.
rejection_scopeNoFor reject only. Default claim rejects that proposition. Use source_identity only when the user explicitly rejects ownership of the cited source or account: all its facts are excluded. Use record_identity only when the user explicitly rejects the cited record while preserving other records on that page. Never infer this narrower scope from table layout.
expected_revisionYesCurrent revision read from the claim; prevents overwriting a concurrent correction.

Output Schema

NameRequiredDescriptionDefault
okYesWhether noticed completed the operation.
dataNoThe operation result when ok is true.
errorNoA human-readable error when ok is false.

A4.4/5.0
Behavior4/5

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

Annotations already declare non-read-only, idempotent, non-destructive, closed-world, so the safety profile is covered. The description adds value beyond them by disclosing the append/preserve semantics ('preserving its ID and revision history') and the concurrency-protection requirement of reading the current revision first, though it says nothing about permissions or error behavior.

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, no filler. The core purpose is front-loaded and the prerequisite instruction follows immediately.

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

Completeness4/5

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

With an output schema present, annotations covering the safety profile, and 75% schema coverage across 8 parameters (including nested validity and enum scopes), the description supplies the essentials. It could still note the personal-vs-team scope distinction (team_id) or what the corrected revision returns, but nothing critical is missing.

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

Parameters4/5

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

Schema description coverage is 75%, so the baseline is 3, but the description meaningfully reinforces two parameters: it enumerates the action modes (correct/reject/retract) and ties expected_revision to a concrete retrieval step. It does not clarify value/validity/team_id semantics, which remain schema-only.

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 names a concrete verb-phrase and resource: saving an explicit user correction, rejection or retraction of a cited person claim. Combined with the title and the mention of claim ID and revision history, an agent can distinguish this mutation pathway from generic siblings like update_person or add_memory.

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?

It gives a clear usage context (only for an *explicit* user correction/rejection/retraction, reinforced by the schema's 'never invent a correction on their behalf') and a prerequisite workflow step: 'Read its current revision first.' It does not name alternative tools (e.g., memory_save for new facts), so it stops short of full when/when-not guidance.

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