Get SAP Protocol Invariants

sap_protocol_invariants

Retrieve current SAP protocol invariants including treasury, registration fee, routing rules, and forbidden actions. Use before registry writes or when fee behavior is unclear.

Instructions

Free read-only protocol invariant card for agents. Returns the current SAP program id, protocol treasury, source-level expected 0.1 SOL registration fee invariant, hosted write routing rules, local sap_payments routes, identity pipeline, and forbidden actions. Use this before SAP registry writes and whenever fee/treasury behavior is unclear. SAP MCP context: Direct synapse-sap-sdk wrapper served by this MCP. Read tools return on-chain state; write tools require signer policy, configured RPC, and the active SAP profile.

Tool Definition Quality

B3.4/5.0
Behavior1/5

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

Description claims 'Free read-only', but annotation has readOnlyHint=false, contradicting the description. The description does not explain this discrepancy.

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

Conciseness4/5

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

Description is front-loaded with key info but includes some redundant context (SAP MCP context). Generally concise.

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 no parameters and an output schema (implied), the description lists return fields and usage context sufficiently.

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

Parameters4/5

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

No parameters; schema coverage is complete. Baseline for 0-param tool is 4.

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

Purpose4/5

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

The description clearly states it returns protocol invariants (specific resources) and lists what is included. It does not explicitly differentiate from siblings but provides usage context.

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?

Explicitly recommends using this tool before SAP registry writes and when fee/treasury behavior is unclear. Provides context about read vs write tools.

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