Sap Modify Cell

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

Annotations already declare readOnlyHint=false and destructiveHint=false, so the safety profile is supplied. The description adds the editable-cell constraint, which is real behavioral value, but says nothing about what happens on a non-editable cell, whether the change is committed to the backend, or whether a save/confirmation step follows.

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?

Three short sentences, front-loaded with the action and followed by the precondition and the verification tool. No filler and nothing repeated from the schema or annotations.

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?

An output schema exists, so return values need not be explained, and safety is covered by annotations. However, with 0% parameter documentation and no statement about post-write behavior (commit, save prompt, error on read-only cell), the definition leaves gaps an agent would likely hit on a first call.

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%, so the description carries the full burden for four required parameters and provides none of it. It does not say what grid_id refers to, whether row is zero- or one-based, whether column is a name or identifier, or what `value` must contain to be accepted.

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: modify a cell value in an ALV grid or table control. The mention of the two container types distinguishes it from field-level siblings like sap_set_field and sap_set_textedit, though those siblings are never named explicitly.

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?

Gives a clear precondition ('Only works on editable cells') and routes the agent to sap_get_cell_info as a verification step before calling. It stops short of contrasting with sap_set_field or sap_set_batch_fields for bulk edits, so the routing is partial rather than exhaustive.

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