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

Annotations already declare the safety profile (not read-only, not idempotent), so the bar is lower, yet the description adds little: it does not say whether resubmission is possible, what happens after a deliverable is submitted, or note that a private operator credential is required. The scoping phrase 'one public mission' is the only added context.

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?

A single efficient sentence with the core action front-loaded and no filler. It is well-sized, though its brevity is partly under-specification rather than disciplined concision.

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 six-parameter mutation tool with no output schema and almost no field documentation, the description is too thin. It omits result behavior, error conditions, and the meaning of most inputs, leaving the agent to guess when invoking it.

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 only 17% (just apiKey), leaving id, txs, demo, repo, and notes undocumented anywhere. The description says 'deliverable' but never maps the deliverable's components (transaction hash, demo URL, repo, notes) to those parameters, so it fails to compensate for the coverage gap.

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 a specific verb and resource ('Submit a deliverable') and scopes it to 'one public Birdfury mission', which is clearer than a bare restatement of the name. It does not, however, contrast itself with siblings like claim_mission or review_submission, so the agent gets no routing help.

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?

There is no guidance on when to use this tool versus alternatives such as claim_mission, review_submission, or get_submission_status. Prerequisites (e.g., that the mission must already be claimed, or that a submission is final) are entirely absent.

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