get_call_template

Creates a ready-to-use call template for a stored procedure, outputting either an EXEC statement with typed placeholders or a pyodbc script that handles all result sets.

Instructions

Generate a ready-to-use call template for a stored procedure.

style='sql' — EXEC statement with typed placeholders for each parameter. style='python' — pyodbc script that executes the SP and collects every result set returned by the server using cursor.nextset().

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
nameYesStored procedure name.
styleNo'sql' or 'python' (default 'sql').sql
schemaYesSchema that owns the procedure.
sourceYesSource name from the metadata cache.

Output Schema

NameRequiredDescriptionDefault
resultYes
Behavior4/5

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

No annotations provided, so description carries burden. It discloses that python style uses cursor.nextset() to collect result sets. It implies the tool generates code without executing the procedure, which is clear.

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 concise, front-loaded with the main purpose, and efficiently presents style options. Every sentence adds value without redundancy.

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?

Given the output schema exists (not shown), the description need not detail return values. It covers the main purpose and style behaviors, but could mention that the procedure must exist in the metadata cache. Still 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% with basic parameter descriptions. The description adds value by explaining how the 'style' parameter affects output format, which is not evident from schema alone.

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 generates a call template for a stored procedure, distinguishing it from siblings like get_stored_procedure which retrieves definition. It specifies the resource and action with two style variants.

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 explains when to use each style (SQL vs Python) and what they produce. It lacks explicit when-not-to-use or alternatives, but the context is sufficient for an agent to choose correctly.

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