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

Adds substantive context beyond annotations: exactly which fields are copied vs excluded, that the caller becomes owner, that the board lands in the caller's personal namespace with a fresh code, and that authorization is enforced imperatively in execute. Annotations already flag it as non-read-only/non-destructive, and the description enriches rather than contradicts them.

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?

Dense, front-loaded sentences with zero filler: what is copied, what is excluded, ownership, namespace placement, and authorization all stated compactly. Every sentence carries distinct information.

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 non-idempotent clone with no output schema, the description covers the full behavioral picture an agent needs: copy semantics, exclusions, ownership/namespace outcome, and authorization requirements. Nothing material is missing.

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 code, title, and source_board_id are all documented in the schema including the auto-generate and default-title behavior. The description's mention of 'fresh unique code' and namespace is consistent but not additive beyond the schema, so 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 (clone) and resource (board), and immediately distinguishes itself from create_board by specifying what is copied (statuses, board files/prompt, title) versus excluded (tasks, comments, members). The agent can tell exactly what this does differently from a plain board creation.

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?

Clear about the scope of the operation and its eligibility conditions (read access, public boards forkable by anyone), which implicitly answers 'when can I use this'. However, it never explicitly names the alternative create_board for building a fresh board or states when cloning would be inappropriate, so it stops short of full when/when-not guidance.

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