"What's new with X" / "latest on Y" / "what happened to Z this week / month / quarter" / "updates on Acme" / "news on Tesla recently" / "what's happening with Apple" — change feed for a company in the last N days/weeks/months in ONE parallel call. Fans out to SEC EDGAR (filings since since), GDELT→GNews fallback (news mentions in window — GDELT preferred, GNews when rate-limited or 5xx), USPTO (patents granted; PatentsView API sunset May 2025 so this soft-fails until reactivated). since accepts ISO date ("2026-04-01") or relative shorthand ("7d", "30d", "3m", "1y"). Returns structured changes[] grouped by source + total_changes count + pipeworx:// citation URIs. Use entity_profile instead when you want the static profile (filings + fundamentals + LEI + patents) regardless of window.

Input Schema

NameRequiredDescriptionDefault
typeYesEntity type. Only "company" supported today.
sinceYesWindow start — ISO date ("2026-04-01") or relative ("7d", "30d", "3m", "1y"). Use "30d" or "1m" for typical monitoring.
valueYesTicker (e.g., "AAPL") or zero-padded CIK (e.g., "0000320193").

TDQS

A5/5.0
Behavior5/5

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

Annotations declare read-only, idempotent, non-destructive. The description adds extensive behavioral context: parallel fan-out to multiple sources, fallback mechanisms, soft-fail for USPTO, and return structure with citation URIs. No contradiction.

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 well-structured: starts with natural language examples, then core function, then source details, parameter explanation, return format, and alternative tool. Every sentence is informative without being verbose.

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?

Despite no output schema, the description covers return structure (changes[], total_changes, citation URIs), all parameters, edge cases (fallback, soft-fail), and distinguishes from related tools. Complete for a complex multi-source tool.

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

Parameters5/5

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

Schema coverage is 100%, and the description adds meaning: explains 'since' accepts ISO dates or relative shorthand (e.g., '7d', '3m'), shows examples, and clarifies that 'value' can be ticker or CIK. The 'type' parameter is limited to 'company'.

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 provides a change feed for a company in a specified time window, with explicit examples. It distinguishes itself from the sibling 'entity_profile' by directing users to that tool for static profiles.

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

Usage Guidelines5/5

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

Provides explicit when-to-use context via example queries and states when to use an alternative ('entity_profile'). Also explains fallback behavior (GDELT to GNews) and parameter syntax.

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

A4.2/5.0
Disambiguation4/5

Tools have distinct purposes with clear descriptions, but ask_pipeworx_beta currently duplicates ask_pipeworx, and the multiple prediction market tools could be confusing without careful reading.

Naming Consistency5/5

All tool names follow a consistent snake_case verb_noun or noun_verb pattern, with no mixing of conventions.

Tool Count3/5

34 tools is high for a single server, covering chain data, Pipeworx research, and prediction markets. While well-organized, the breadth pushes the boundary of manageable scope.

Completeness4/5

The tool set covers major query operations for chains, entities, and data sources, with subscription and memory features. Minor gaps like lack of chain creation are acceptable given the server's focus on data retrieval.
