Manifest Get Orderbook

manifest_getOrderbook

Read-onlyIdempotent

Get the current orderbook for a Manifest market. SAP MCP context: This Synapse AgentKit tool is served beside the sap_* SDK tools. Use sap_agent_identity_plan, sap_payments_register_agent, sap_payments_update_agent, and sap_publish_tool_by_name when the capability should become part of an on-chain SAP agent profile or tool registry entry.

SAP MCP execution guidance: Intent: read/discovery workflow. Pricing: paid read-premium; estimate first, then use sap_payments_call_paid_tool when the runtime cannot replay x402 natively. Routing: paid hosted call; call sap_estimate_tool_cost first, then use sap_payments_call_paid_tool if the runtime cannot handle x402 natively. Signer boundary: hosted reads/builders never receive keypair bytes; value-moving results must be finalized locally when signing is required.

A3.7/5.0

Behavior4/5

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

Annotations already indicate readOnlyHint, idempotentHint, and destructiveHint false. The description adds value by disclosing that the tool is 'paid read-premium', requires cost estimation, and that 'hosted reads/builders never receive keypair bytes', which are behavioral constraints beyond the annotations.

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

Conciseness2/5

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

The description is repetitive and includes lengthy boilerplate 'SAP MCP context' and 'execution guidance' that appears twice (once in description, once in input schema description). This reduces conciseness and front-loading of key information.

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 presence of an output schema (not shown), the description does not need to detail return values. It covers the core function and payment workflow. However, it lacks specific guidance on what the orderbook contains (e.g., bids/asks). Overall sufficient for the tool's complexity.

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?

Input schema coverage is 100% and the schema already describes parameters (marketId as Solana public key, depth as number). The description does not add additional meaning or examples beyond what the schema provides, so baseline score 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 'Get the current orderbook for a Manifest market', which is a specific verb+resource. It distinguishes from sibling tools like manifest_placeLimitOrder and manifest_cancelOrder which perform different actions.

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

Usage Guidelines3/5

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

The description mentions 'read/discovery workflow' but does not provide explicit when-to-use or when-not-to-use guidance compared to alternatives. The generic SAP MCP context is not specific to this tool and lacks actionable selection criteria.

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