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

No annotations are provided, so the description carries the full burden. It usefully discloses server-side type coercion and the accepted boolean string forms (on/off, true/false, 1/0, yes/no), which is real behavioral detail. However, it omits permissions/auth requirements, error behavior for unknown keys, and whether changes are reversible.

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?

Four short sentences, front-loaded with the purpose, followed by coercion rules, a discovery pointer, and a concrete example. Efficient with minimal waste, though the example sentence is somewhat verbose.

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?

For a 3-parameter mutation tool with no annotations and no output schema, the description covers purpose, coercion semantics, and how to discover valid keys. It leaves out permissions and failure modes, but the discovery pointer and coercion details make it largely complete for correct invocation.

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 schema already documents all three parameters. The description adds some value by elaborating on coercion and adding 'yes/no' to the boolean formats, but the schema already covers most of this. Baseline 3 applies.

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 ('change') and resource ('a board setting'), clearly distinguishable from siblings like update_board, get_board_settings, and get_board_settings_schema. An agent can tell exactly what this tool does without opening the schema.

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 names get_board_settings_schema as the way to discover available keys and types, which is explicit routing guidance. It does not state when NOT to use it or contrast with update_board, but the usage context is clear.

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