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

Annotations only declare non-read-only, non-destructive, non-open-world; the description adds substantive behavior beyond that — validation against the step's acceptance criteria, the CHASE→FEAST transition and IVP award on acceptance, and that human-action steps are never auto-completed. It stops short of describing the rejection path or whether a failed submission consumes the attempt.

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 sentences, all front-loaded with the action first and the consequences after; nothing is redundant. Dense domain jargon (CHASE→FEAST, IVP, Kill Confirmed) is used without expansion, which slightly raises interpretation cost for a newcomer.

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?

With no output schema, the description correctly explains the key return states (accepted vs. 'awaiting_human_confirmation'). The main remaining gap is the failure/rejection outcome and any error signaling, which an agent needs in order to react to an unsuccessful submission.

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 50%: deliverable_text is documented, but 'step' only carries a 1–40 integer bound. The description implies 'step' identifies the mission step whose acceptance criteria will be checked, which adds some meaning, but it never says how to obtain the correct step number, so the gap is only partially closed.

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 ("Submit a deliverable for a CHASE mission") plus the resulting state transition, which distinguishes it from siblings like get_mission and start_mission that only read or initiate. An agent can tell this is the completion/submission action 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?

Usage is implied rather than stated: it is the tool you call once a mission's work is done, and it explains that real-world-action steps return 'awaiting_human_confirmation'. There is no explicit when-not guidance, no mention of what to do on rejection, and no named alternative for retrieving or restarting a mission.

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