UpdateLocalDefinitions

Updates local definitions (class-local types/constants) in an ABAP class. Manages lock, update, unlock, and optional parent activation.

Instructions

TDQS

A3.7/5.0
Behavior4/5

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

With no annotations, the description carries the full behavioral burden and does disclose meaningful context: it manages lock, update, unlock, and optional parent-class activation. That tells the agent the tool handles locking automatically and that activation is a separate optional step. It still omits permission/authorization needs and failure behavior, keeping 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?

Two tight sentences, front-loaded with the core action and resource, followed by the operational behavior. No wasted text; it could be marginally more informative without becoming bloated, but it is well-structured.

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 mutation tool with no annotations and no output schema, the description covers the action, the target, and the lock/activation lifecycle. Combined with full schema coverage of parameters, it is largely complete, though it could note transport or error-handling context.

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%, so the schema already documents all five parameters including the detail enum and transport_request note. The description adds no additional parameter meaning beyond what the schema provides, so the baseline of 3 applies.

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 (Update) and resource (local definitions) scoped to an ABAP class, with a parenthetical clarifying it means class-local types/constants. This distinguishes it from siblings like UpdateLocalTestClass and UpdateLocalMacros, though it does not explicitly name those alternatives.

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?

Usage is only implied — the agent can infer this is for modifying existing local definitions. There is no explicit when-to-use guidance versus UpdateLocalTypes/UpdateLocalMacros, and no prerequisites (e.g. transport_request requirements for transportable objects) are surfaced in the description.

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