Describe stored procedure

describe_procedure

Retrieve stored procedure parameters and SQL definition (CREATE PROCEDURE body) without executing it.

Instructions

Get parameters and the SQL definition (CREATE PROCEDURE body) for a stored procedure. This tool only reads the procedure's metadata — it never executes it.

Input Schema

schemaYesSchema name, e.g. 'dbo'
procedureYesProcedure name
Behavior5/5

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

With no annotations provided, the description takes full responsibility and explicitly states 'This tool only reads the procedure's metadata — it never executes it.' This is a crucial safety guarantee for a database tool and goes beyond basic purpose.

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 two sentences with the main purpose front-loaded and a concise safety clarification. No unnecessary words or repetition.

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?

For a simple two-parameter tool with no output schema, the description fully covers purpose, scope, and safety. It is complete enough for an agent to select and 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?

The input schema already documents both required parameters with examples (e.g., 'dbo' for schema), achieving 100% coverage. The description adds no extra parameter meaning beyond what the schema provides.

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 'Get parameters and the SQL definition (CREATE PROCEDURE body) for a stored procedure', specifying the verb and resource. It also distinguishes from sibling describe tools by focusing on procedures specifically.

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 description implies usage by stating what it retrieves, but does not explicitly say when to use this over alternatives like describe_table or list_procedures. There is no mention of exclusions or alternative tools.

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