GetProgramVersions

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

No annotations are provided, so the description carries the full behavioral burden, and it does substantial work: it declares read-only status, enumerates the return shape (versionId, author, updatedAt, title, transportRequest/transportDescription, content_uri), and explains the non-obvious batch/recordable contract where the call returns empty content and must be read back by number. It omits any mention of result limits, pagination, or authorization requirements for a potentially long version history.

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?

Two sentences, front-loaded with the read-only tag and the core purpose, then the return fields, then the batch caveat. Dense but every clause carries information; the batch sentence is long but describes behavior an agent cannot infer elsewhere.

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?

With no output schema and no annotations, the description compensates by listing exactly what each version record contains and how the batch mode answer is retrieved. It is nearly complete for a simple one-parameter list tool; only pagination/size expectations are unaddressed.

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% and the single parameter is already documented as "ABAP program name." The description restates that the program is named by program_name without adding format, naming-convention, or case-sensitivity guidance, so baseline 3 is appropriate.

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?

States a specific verb and resource ("Lists the version history of the ABAP program named by program_name") and even enumerates the returned fields. It does not explicitly name the sibling it is not — e.g., GetProgramVersionSource or GetProgramVersionDiff — so the agent must infer the split from the field list (content_uri) rather than being routed.

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?

Usage is only implied: "Lists the version history" tells the agent the general occasion, and the mention of content_uri hints that source retrieval is a separate follow-up call. There is no explicit statement of when to prefer this over GetObjectVersions, GetProgramVersionSource, or GetProgramVersionDiff, and no prerequisites are given.

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