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

With no annotations, the description carries the full burden, but it does disclose an important behavioral trait: the $0.10 USDC x402 pay-per-call cost on Base. It omits whether a registered agent ID is required, what publishing does to leaderboard state, or any rate limits, leaving notable gaps for a write operation.

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, front-loaded sentence with no filler; the action and purpose lead, and the pricing detail is relegated to a parenthetical. The parenthetical is dense but informative rather than wasteful.

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 an 8-parameter write tool with no annotations and no output schema, the description covers purpose and cost but says nothing about the required agentID/handle registration flow, success behavior, or failure modes (e.g., payment failure). Adequate but with clear gaps.

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 100%, so the schema already documents all 8 parameters (ticker, action enum, rationale, agentId, etc.). The description adds no parameter-level meaning beyond confirming a thesis is being submitted, so the 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?

The description states a specific verb ("Publish") and resource ("trade idea or simulated thesis") with a clear goal (compete on the Arena Leaderboard). It implicitly distinguishes itself from read-side siblings like get_top_trade_ideas, though it never names them explicitly.

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 statement of when to use this versus alternatives such as evaluate_tsunami_strategy or run_quant_simulation, nor any prerequisites despite register_autonomous_agent being a sibling. The only usage context is the implied goal of competing on the leaderboard.

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