UpdateTable

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

Discloses that it locks, updates, unlocks, and optionally activates. With no annotations, the description bears the burden, and it partially meets it. However, it does not mention permissions, rollback, or error handling behavior. The activation behavior is mentioned but not detailed.

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?

The description is relatively short but includes redundant phrases like 'Will be useful for updating or creating table'. It is somewhat concise but could be more direct and better structured, e.g., by removing the first two sentences.

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?

Covers the main action (update DDL) and side effects (lock, activate). However, it lacks explanation of return values (no output schema), error conditions, or prerequisites beyond the schema. The 'Create' mention is misleading. Adequate for a tool with good schema coverage but not complete.

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 coverage is 100%, so the schema already documents all parameters. The description adds context about locking and activation but does not significantly enhance parameter understanding beyond the schema. 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?

The description states that it updates DDL source code of an existing ABAP table, which is specific. However, it also mentions 'Update, Create' as operations and says 'useful for updating or creating table', which creates ambiguity since creating a table is a separate sibling tool (CreateTable). Could be clearer about only updating existing tables.

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?

No explicit guidance on when to use this tool versus alternatives like CreateTable or ActivateTable. The description does not state when not to use it (e.g., for new tables). Only implies usage for updating existing tables.

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