What's changed

whats_changed
Read-onlyIdempotent

Recent dated price-change capsules, newest first — the freshness a base model cannot have. Each capsule is a cleared, two-source-corroborated movement of a vendor's published price (vendor, plan, before→after, date, sources). Optionally filter to changes on/after a date or within one section. Returns an empty list with a clear note when nothing qualifying has been recorded yet.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
sinceNoOnly changes detected on or after this ISO date (YYYY-MM-DD).
sectionNoTheme slug to query (default "ai-receptionists"). A theme is any of the 271 pricing topics this index covers: the deep hub sections (e.g. ai-receptionists) plus the many catalog topics (e.g. vpn-services, web-hosting, password-managers). Call list_sections or list_coverage for the full slug list — do not assume the old four-section set.

A4.4/5.0
Behavior4/5

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

Annotations already declare readOnlyHint=true and idempotentHint=true. The description adds that capsules are 'cleared, two-source-corroborated' and that an empty list with a note is returned when no qualifying data exists, providing useful behavioral context beyond annotations.

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?

The description is three concise sentences. The first states the core purpose, the second details the output content, and the third covers filters and edge cases. No wasted words.

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?

For a read-only listing tool with two optional parameters and no output schema, the description provides sufficient context: purpose, output structure, filter options, and empty result behavior. A bit more detail on the capsule fields could help, but it's adequate.

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 100%, so baseline is 3. The description adds significant value for the 'section' parameter by explaining themes, mentioning 271 topics, and advising to call list_sections for the full list, which goes well beyond the schema's description.

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 'Recent dated price-change capsules, newest first', explaining exactly what each capsule contains. It distinguishes from siblings by focusing on recent changes, not full history or comparisons.

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?

The description mentions optional date and section filters, providing context for when to use them. While it doesn't explicitly list alternatives, the context of 'recent changes' versus historical or comparative tools is clear.

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

A4.3/5.0
Disambiguation4/5

Tools have distinct purposes, but some overlap exists between 'compare' and 'compare_products' (both do side-by-side comparisons, one for vendors, one for products). However, descriptions clarify the domain difference, and most tools have clear boundaries.

Naming Consistency5/5

All tool names follow a consistent verb_noun snake_case pattern (e.g., list_sections, search_vendors, get_benchmark). No mixed conventions or vague verbs.

Tool Count4/5

19 tools is slightly on the higher side but appropriate for a comprehensive pricing index covering 271 themes. Each tool has a clear role, and the count does not feel bloated.

Completeness5/5

The tool surface covers listing, searching, comparing, finding, detailed info retrieval, and price change tracking. No obvious gaps for the domain of pricing and comparison.
