stageRepo

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

The annotations already state readOnlyHint=false and destructiveHint=false. The description adds that this stages local changes and previews objects/states for a commit, which helps clarify the non-read-only side effect. However, it does not disclose authentication requirements (user/password) or any further impact on the repository state.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

A single sentence that front-loads the action and includes only essential information. The phrase 'which objects would go, with their state' efficiently communicates the tool's output focus without filler.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

There is no output schema, so the description carries the responsibility of explaining return semantics; it partially does with 'which objects would go, with their state'. Still, it lacks guidance on how to obtain the repo object, the role of the optional user/password parameters, and the side effects of staging. Adequate but with notable gaps.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the baseline is 3. However, the schema descriptions are minimal ('The Git repository object', 'The username', 'The password') and the tool description adds no meaning to these parameters. It neither clarifies how to obtain the repo object nor explains the roles of user and password.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses a specific verb ('Stage') and resource ('local changes of an abapGit repository'), then clarifies the purpose ('for a commit') and what information the tool provides ('which objects would go, with their state'). This makes it clearly distinguishable from sibling git operations like gitPullRepo or pushRepo.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies the staging step before a commit but gives no explicit when-to-use or when-not-to-use guidance. No alternatives are named and no exclusions are stated, leaving the agent to infer the context from the description alone.

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