SentEdge Idea Machine

Exclusive buyout ($1.00 USDC)

buy_exclusive

Buy an idea outright for $1.00 USDC via x402: full markdown delivered, idea delisted from sentedge.ai, no further sales. First come, first served — a losing racer is never charged. This tool returns the exact payment instructions.

A4.2/5.0

Behavior4/5

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

With no annotations, the description provides key behavioral traits: the exclusive buyout effect (delisting), the race condition ('first come, first served' and losing racer not charged), and the return type (payment instructions). It could be more explicit about failure modes or authorization needs, but it discloses the main behavioral implications.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is three sentences with no redundancy: first sentence states core action, second adds concurrency detail, third clarifies return type. Every sentence adds value, and the most critical information is front-loaded.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's simplicity (1 parameter, no output schema), the description covers all essential aspects: what it does, how to use it (slug), key behavioral notes (race, delisting, no charge on loss), and what to expect (payment instructions). Minor omissions like exact payment flow are reasonable for this scope.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The single parameter 'slug' is described in the schema as 'Idea slug', which is self-explanatory given the context. Schema coverage is 100%, so the description adds no additional meaning beyond what the schema provides. Baseline 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action ('Buy an idea outright'), the resource ('idea'), the price ($1.00 USDC), the method (via x402), and the effects (full markdown delivered, idea delisted). It distinguishes from siblings like get_full_idea (read-only) and how_to_pay (payment info).

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies when to use the tool (to purchase exclusivity) and notes the 'first come, first served' race condition. However, it lacks explicit guidance on when not to use it or direct comparison with alternatives like get_full_idea for non-exclusive access.

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