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

With no annotations, the description carries the full burden. It implies a write/finalizing operation (task 'completion') yet discloses nothing about permissions, side effects, reversibility, or whether operator handoff is automatic. The only behavioral signal is a partial list of outputs, which does little to tell the agent what will happen when it calls this.

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?

It is a single sentence with no padding, so structure is fine, but the terseness comes at the cost of clarity — the jargon-dense fragments ('Outcome A2A task', 'typed diffs') pack in terminology without conveying a usable instruction.

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 and no annotations, the description is the sole carrier of behavior and return information, and it is insufficient: no return format detail beyond vague nouns, no permissions, no error behavior, and no parameter documentation. A tool with 2 params where one is required needs substantially more.

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?

Two parameters with 0% schema description coverage means the schema documents neither 'goal' nor 'constraints'. The description's 'concrete x402 shipping goal' is the only hint at what 'goal' should contain, and 'constraints' is entirely unexplained, leaving the agent to guess the expected format.

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 never states a clear verb+resource for what the tool does; 'Outcome A2A task' is a label, not an action, and 'complete_oracle_task' is only restated. It gestures at outputs (typed diffs, handoff notes, revenue/risk) but an agent cannot tell what invoking it actually accomplishes versus sibling tools like oracle_ask.

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 when-to-use guidance, no exclusion criteria, and no mention of any sibling such as oracle_ask or oracle_diagnose_402. The phrase 'concrete x402 shipping goal' hints at a domain but gives no condition for selecting this tool over the other six oracle_* tools.

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