Aggregate AI sentiment

get_sentiment_distribution

Read-onlyIdempotent

Aggregate AI labels over a shared selection. model:"all" compares independent annotators and their coverage; model:"consensus" reads the stored panel majority. Choose compare_models and agreement_field for pairwise Cohen's kappa and quadratic weighted kappa, with explicit denominators. Labels are interpretations, not ground truth; subjectivity is weak evidence and its caveat must accompany findings.

A4/5.0

Behavior4/5

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

Annotations already establish readOnly/idempotent/non-destructive, so the bar is lower, and the description still adds substantive context beyond them: it discloses that kappa results come with explicit denominators and, importantly, that labels are model interpretations rather than ground truth and that subjectivity is weak evidence requiring a caveat. That interpretive framing is real behavioral value the annotations cannot convey.

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

Conciseness4/5

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

Four dense sentences with no filler; the mode semantics are front-loaded after a short opening clause. The closing caveat sentence is slightly editorial but carries a genuine usage warning, so it earns its place.

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, return values need no explanation, and the description covers the distinctive behavior (aggregation modes, pairwise agreement metrics, interpretive caveat) adequately. Coverage of the many filter parameters is thin, but those are largely self-documenting in the schema.

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 coverage is only 50% across 14 parameters, so the description must compensate, and it does so for the most consequential ones: it explains the semantics of model:"all" vs "consensus" and the role of compare_models plus agreement_field in producing Cohen's and quadratic weighted kappa. The remaining filter parameters (hijri_*, keyword_mode, keyword_aliases) are left to the schema.

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

Purpose4/5

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

The description gives a clear verb ('Aggregate') and resource ('AI labels over a shared selection') and explains the two headline modes, model:"all" and model:"consensus". However, it never says the tool produces a sentiment *distribution* of counts, and it does not distinguish itself from the similar-sounding siblings get_field_distribution or get_topic_distribution, so the agent must infer the distinction.

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 explicit conditional guidance for the mode parameters: use model:"all" to compare independent annotators and coverage, model:"consensus" for the stored panel majority, and add compare_models/agreement_field for pairwise kappa. What is missing is any guidance on when to choose this tool over siblings such as search_by_sentiment or get_field_distribution.

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