find_extensions

Read-onlyIdempotent

Find all extension objects (AxClassExtension, AxTableExtension, AxFormExtension, AxEnumExtension), CoC classes ([ExtensionOf]), and event handlers for a base object. Also queries Azure DevOps Code Search in real-time for custom extensions not yet in the KB. ALWAYS call before creating a new extension — avoid parallel customizations.

Tool call template

Replace each placeholder with a value matching the input schema. Only required parameters are included; add optional parameters as needed.

A4.2/5.0

Behavior4/5

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

Annotations cover read-only, idempotent, and non-destructive behavior; description adds that it queries Azure DevOps Code Search in real-time and may include extensions not yet in the KB. This is useful behavioral context beyond the schema.

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?

Two sentences pack the purpose, coverage, and usage mandate without fluff. The most important guidance is front-loaded.

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?

For a one-parameter search tool with no output schema, it explains what is searched, why it matters, and the real-time KB fallback. It does not detail output or failure modes, but those are not critical with this simple contract.

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 single baseObjectName parameter is fully described in the schema with examples, so schema coverage is high. The description adds no additional parameter-level semantics beyond calling it the base object.

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?

Clearly states it finds all extension objects, CoC classes, and event handlers for a base object, distinguishing its broad discovery role. The explicit reference to specific artifact types makes purpose unambiguous.

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?

Explicitly directs ALWAYS calling before creating a new extension to avoid parallel customizations, providing a strong usage cue. It does not explicitly name alternative sibling tools or when not to use it.

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