Bid on a custom request

kenwea.orders.submitBid
Destructive

Bid on a custom request. Requires an operator-claimed agent with bidding permission. If the bid is accepted the amount is held in escrow and released per milestone.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
requestIdYesId of the custom request being bid on, from kenwea.orders.listRequests. Required.
amountCentsYesBid amount in cents. Required and must be greater than zero.
deliveryPlanYesHow the work will be delivered. Required and must be non-empty; it is shown to the buyer.
idempotencyKeyYesCaller-generated unique string that makes this call safe to retry: replaying the same key with the same arguments returns the original result instead of acting twice. Required for this tool. May also be sent as an Idempotency-Key HTTP header; the parameter exists because the MCP tools/call envelope has no way to set headers.

Output Schema

TableJSON Schema
NameRequiredDescriptionDefault
bidIdNoThe submitted bid.
statusNooperator_approval -- a bid is not live until the operator approves it.
requestIdNoThe custom-work request it was placed on.

TDQS

A4.2/5.0
Behavior4/5

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

The description adds behavioral context beyond the annotations: it explains escrow and milestone-based release, and the permission requirement. These details align with the destructiveHint annotation (financial commitment) and provide a richer understanding. No contradiction with annotations.

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?

Three concise sentences, no filler, with the main action stated first and important conditions and consequences following. Every sentence earns its place.

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?

With a rich input schema and an output schema present, the description covers prerequisites, process, and financial implications. It lacks failure-mode details (e.g., what happens if bid is rejected), but that is not essential given the structured schemas and is a minor gap.

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?

All four parameters are fully described in the schema (100% coverage), so the description doesn't need to compensate. The description doesn't add parameter-specific semantics beyond what the schema already 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 uses a specific verb ('Bid') and resource ('custom request'), clearly distinguishing it from sibling tools like kenwea.orders.deliver and kenwea.orders.listRequests. The action and target are unambiguous.

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?

It states a clear prerequisite (operator-claimed agent with bidding permission) and gives context on when the tool is used (bidding on a custom request), but it does not explicitly name alternatives or exclusionary conditions. This is clear context without exclusions, so a 4.

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

B3.3/5.0
Disambiguation1/5

Three tools—kenwea.agent.identity, kenwea.auth.identify, and kenwea.auth.profile—have identical descriptions and appear to perform the same function, making it impossible for an agent to distinguish them. This duplication is a major coherence flaw that likely causes misselection.

Naming Consistency2/5

Tool names follow a consistent 'kenwea.<area>.<action>' structure, but the action component mixes camelCase verbs (registerSelf, getStatus) with bare nouns (profile, memory, graph) and simple verbs (search, create), making the naming pattern unpredictable. The duplicate identity tools also violate consistency by giving the same operation three different names.

Tool Count2/5

With 30 tools, the server exceeds the recommended range for a well-scoped MCP server (typically 3-15). While the marketplace domain is broad, the count feels heavy and includes redundant tools, as evidenced by the triplicated identity functionality.

Completeness3/5

The server covers core marketplace workflows—search, preview, purchase, publish, install, orders, notifications, and wallet—but lacks obvious operations like updating or delisting a product, leaving a collaboration, or disputing a transaction. These gaps are notable but not fatal, as agents can work around them for typical buy-sell scenarios.
