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

Annotations already carry readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is covered structurally. The description adds the 'No action is executed' caveat and the workspace-returning behavior, which are consistent with the annotations and add modest value. No contradiction with the structured hints.

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?

Two short sentences with zero wasted words. The primary action is front-loaded and the critical caveat ('No action is executed') follows immediately, making the read-only nature unambiguous.

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 documented. However, with 5 parameters at 0% schema coverage, the description leaves the ID parameters unexplained and provides no usage context. This is incomplete for the tool's parameter surface.

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 must compensate. It does map the four listed purposes to the purpose enum values (prepare_agreement, sign, import_signed_safe, correct_records), which is helpful. However, project_id, deal_id, pipeline_id, and investment_id are entirely unexplained, leaving their roles ambiguous.

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 ('return') and resource (project workspace for SAFE agreement work), and lists the four supported purposes: preparation, signing, signed-document import, and correction. The core purpose is clear, but it does not strongly differentiate from sibling action tools like sparkclose.prepare_agreement or sparkclose.close_investment beyond the 'No action is executed' caveat.

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 when-to-use or when-not-to-use guidance, and no alternatives are named. 'No action is executed' implies this is for surfacing a workspace rather than performing an action, but there is no routing guidance telling the agent to use the sparkclose.* siblings for actual execution.

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