Hyperscaler Deal Tracker

hyperscaler_deals

Read-onlyIdempotent

Use this when the user asks about hyperscaler or AI data center deals: live feed of Stargate, OpenAI, Anthropic, Microsoft, Oracle, CoreWeave, AMD, NVIDIA, sovereign-AI deals. Pulls from dchub news pipeline, extracts $-figures + MW via regex, classifies by actor. 10-min refresh. Use for tracking AI capex events ($1B+/week typical), capacity announcements, and competitive intel. Do NOT use for the full historical M&A comp set (use list_transactions) or a single-deal teardown with grid context (use deal_autopsy); this is the live $1B+ AI-capex feed. limit 1-500. Hyperscaler leases and purchases only; for all M&A use list_transactions.

TDQS

A4.4/5.0

Behavior4/5

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

Annotations already cover readOnlyHint/idempotentHint/destructiveHint, but the description adds real behavioral context beyond them: the dchub news pipeline source, regex extraction of $-figures and MW, actor classification, a 10-minute refresh cadence, and the scope limit (hyperscaler leases and purchases only). It does not discuss auth or pagination beyond the limit bound, which keeps it short of a 5.

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?

Front-loaded with the use trigger and scope, and most sentences earn their place. Minor redundancy: the routing to list_transactions for M&A is stated twice ('full historical M&A comp set' and 'for all M&A use list_transactions'), which costs a little efficiency.

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?

With an output schema present, return values need no explanation. The description covers scope, data source, refresh cadence, and both sibling alternatives, leaving nothing an agent needs to select or invoke the tool correctly.

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?

Schema coverage is 100% with a single, fully documented limit parameter, so the schema carries the parameter semantics. The description's 'limit 1-500' merely restates the schema bounds and adds no new meaning, making the baseline 3 correct.

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?

States a specific verb and resource (live feed of hyperscaler/AI data center deals), enumerates the actors covered (Stargate, OpenAI, Microsoft, Oracle, CoreWeave, etc.), and explicitly distinguishes itself from list_transactions and deal_autopsy. An agent can route correctly without opening any schema.

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?

Gives an explicit when-to-use trigger (user asks about hyperscaler or AI data center deals) plus two named exclusions with the alternative tool for each: full historical M&A comp set -> list_transactions, single-deal teardown with grid context -> deal_autopsy. Nothing is left to inference.

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