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.

A3.7/5.0

Behavior4/5

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

Annotations already cover the read-only, idempotent, non-destructive profile, so the description's job is to add analytical context — and it does: labels are model interpretations not ground truth, subjectivity is weak evidence, and its caveat must accompany findings, plus kappa denominators are reported explicitly. This is substantive epistemic context an agent cannot get from the annotations.

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, front-loaded with the core action and then the mode selection, with no filler. Some phrasing is heavily compressed jargon ("explicit denominators"), but nothing is wasted.

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-shape explanation is unnecessary, and the description covers the non-obvious parts: mode switching, pairwise agreement statistics, and the interpretive caveat. It stops short of explaining how the filter set combines (AND semantics in `exact`) or default model behavior, which matters for a 14-parameter tool.

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?

At 57% schema coverage across 14 parameters, some compensation is required: the description meaningfully explains model:"all"/"consensus" semantics and the purpose of compare_models and agreement_field (pairwise Cohen's and quadratic weighted kappa). But it says nothing about the many filter parameters (exact, keyword_mode, hijri_year, date bounds) or the dependency that agreement_field presumably requires compare_models.

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?

States a specific verb and resource — aggregating AI labels (polarity/centrality/subjectivity) over a shared selection — and names the two special modes ("all", "consensus") that make this tool distinctive. However, it never explicitly distinguishes itself from close siblings such as get_field_distribution or search_by_sentiment, so an agent must infer the boundary.

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

Usage Guidelines3/5

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

It gives real internal-mode guidance: model:"all" for independent annotators vs "consensus" for the stored panel majority, and when to reach for compare_models plus agreement_field. What it lacks is tool-level guidance — no statement of when to call this instead of get_field_distribution, get_topic_distribution, or search_by_sentiment.

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