launch_transaction

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. It does add one useful trait ("preserves unrelated SAP sessions"), but says nothing about what happens to an already-open transaction in the same session, permission/auth requirements, or execution side effects.

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 front-loaded clause with no filler or repetition; it is well-structured. Its brevity is closer to under-specification than to wasteful padding, but as sizing/structure goes it is efficient.

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 annotations, no output schema, and 0% parameter documentation, the description is too thin for a 3-parameter action tool. The one session-preservation note is a good start but leaves the agent missing parameter format, side effects, and return behavior.

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 0% across 3 parameters. The description hints at the transaction argument but never states the expected format (e.g., SAP transaction code), and completely ignores return_screenshot and as_file_target_folder, so it does not compensate for the schema gap.

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 ("Start a transaction") plus a scoping clause ("in the configured session"), which cleanly pairs with the sibling end_transaction. It does not explicitly name alternatives, but the action is unambiguous.

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 gives no when-to-use/when-not guidance and no prerequisites, such as whether a session must already be configured or whether this can be called mid-transaction. The only routing signal is implicit from the sibling name end_transaction.

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