Read-onlyIdempotent

Analyze the blast radius of a proposed schema change: FK dependencies, affected views, row count, risk score. [ARCHITECT tier]

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
intentYesDescribe the change: 'rename vehicle_id to vehicle_uuid on trips', 'drop column X'
connectionNoTarget connection name from this tenant's inventory. Call `list_connections` to see every name + dialect, then match semantically to the user's intent (e.g. 'analytics' → a connection named `*-analytics-*`; 'prod' → a connection with `prod-` prefix). If the user didn't specify, use the tenant's default (first added). Do not invent names — resolve from `list_connections` output.

  7. First observed

TDQS

A3.6/5.0
Behavior3/5

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

Annotations already declare readOnlyHint=true, idempotentHint=true, and openWorldHint=true, so the safety profile is covered. The description adds what dimensions are inspected (FK deps, views, row count, risk score) but does not disclose cost, latency, or depth limits for a potentially expensive dependency-graph walk on a live connection.

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?

A single front-loaded sentence that names the action, the scope, and the concrete outputs, followed by a compact tier tag. Zero filler.

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?

An output schema exists, so return values need not be explained, and the two parameters are fully documented in the schema. The description covers purpose and outputs; only the tier semantics and any cost/limit expectations are left implicit.

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 description coverage is 100%, and the schemas for both 'intent' and 'connection' are unusually rich, including examples and a resolve-via-list_connections protocol. The description adds nothing beyond the schema, so the baseline of 3 is appropriate.

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 ('Analyze'), a precise resource ('blast radius of a proposed schema change'), and enumerates the concrete artifacts it produces (FK dependencies, affected views, row count, risk score). It does not name or differentiate itself from adjacent siblings like generate_migration or analyze_table, so it lands at 4 rather than 5.

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?

The phrase 'proposed schema change' implies the trigger condition (pre-change assessment), and the '[ARCHITECT tier]' tag hints at availability gating. However, there is no explicit when-to-use, no when-not, and no routing to alternatives such as generate_migration, which an agent would need to choose correctly.

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