Server Quality Checklist

Profile completionA complete profile improves this server's visibility in search results.

Latest release: v0.4.0
Disambiguation4/5
Tools are generally distinct across settlement (HTLC) and RFQ/swap domains. However, create_rfq and swap_quote have overlapping functionality, with swap_quote acting as a higher-level wrapper, which could cause confusion about which to use. Otherwise, well-separated.
Naming Consistency3/5
Most tools follow verb_noun (create_htlc, list_my_trades) but swap tools use noun_verb (swap_cancel, swap_execute), creating inconsistency. The pattern is mostly predictable, but the mix reduces coherence.
Tool Count5/5
13 tools cover the full lifecycle of atomic swaps and OTC trading without being excessive. Each tool has a clear role, and the count is well-scoped for the server's purpose.
Completeness5/5
The tool surface covers the complete workflow: RFQ creation, quoting, execution, cancellation, HTLC locking, status polling, refund, and withdrawal. No obvious gaps for the core domain.
Average 4.6/5 across 13 of 13 tools scored. Lowest: 4/5.

How is the quality score calculated?

The overall quality score combines two components: Tool Definition Quality (70%) and Server Coherence (30%).

Tool Definition Quality measures how well each tool describes itself to AI agents. Every tool is scored 1–5 across six dimensions: Purpose Clarity (25%), Usage Guidelines (20%), Behavioral Transparency (20%), Parameter Semantics (15%), Conciseness & Structure (10%), and Contextual Completeness (10%). The server-level definition quality score is calculated as 60% mean TDQS + 40% minimum TDQS, so a single poorly described tool pulls the score down.

Server Coherence evaluates how well the tools work together as a set, scoring four dimensions equally: Disambiguation (can agents tell tools apart?), Naming Consistency, Tool Count Appropriateness, and Completeness (are there gaps in the tool surface?).

Tiers are derived from the overall score: A (≥3.5), B (≥3.0), C (≥2.0), D (≥1.0), F (<1.0). B and above is considered passing.

Tool Scores

Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations are absent, so the description must cover behavioral traits. It only states 'Read-only' and 'list the caller's trades.' No mention of output ordering, pagination behavior beyond schema, rate limits, or authorization needs. For a list operation, more detail on what to expect would be helpful.
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?
The description is concise and front-loaded with the core purpose in the first sentence. It then provides use-case guidance, exclusions, and a follow-up hint. Could be slightly more structured, but every sentence serves a clear purpose.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no output schema, the description could explain what fields the returned trades contain or default sorting. It mentions a follow-up tool (get_htlc) but lacks details on output format or behavior when no trades exist. Still, it covers usage context and alternatives well.
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 has full description coverage (100%), so baseline is 3. The description adds 'Optional status filter narrows the page,' which restates what the schema already says about the status parameter. No additional meaning is provided for page or pageSize beyond schema descriptions.
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 'List the caller's trades (active + historical). Read-only.' It identifies the specific resource (caller's trades) and scope (active+historical). It explicitly distinguishes from sibling tools like list_open_rfqs and get_htlc.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines5/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
Provides explicit when-to-use scenarios: 'when an agent restarted/lost context and must resync in-flight settlements, or showing the user their trade history.' Also gives clear when-not-to-use: 'DO NOT USE WHEN: you need open market demand (use list_open_rfqs) or per-leg HTLC detail for one trade (use get_htlc).' Includes follow-up guidance.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided. Description mentions idempotency via client_request_id but does not detail side effects, error states, or what happens on failure. The tool's impact on state machine is implied but not fully explained.
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?
Concise and well-structured: main purpose, usage guidance, then parameter notes. No redundant information, each sentence adds value.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
No output schema. Description explains purpose and param notes but lacks details on return value, error handling, or how this tool fits into the overall trade lifecycle. Could be more complete for a complex settlement tool.
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?
Schema coverage is 100%, baseline 3. Description adds value with notes on role requirements, txHash format, and chainType defaults, clarifying usage beyond schema definitions.
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?
Description clearly states the tool's purpose: recording the on-chain HTLC lock tx hash to advance settlement, with DVP guarantee. Differentiates from siblings like refund_htlc and withdraw_htlc by focusing on the lock step.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines5/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
Explicit USE WHEN and DO NOT USE WHEN conditions, specifying the prerequisite (trade accepted, lock tx broadcast). Provides clear context for correct invocation.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations exist, so description carries full burden. Declares 'Read-only', describes return fields, and mentions pagination. Does not detail rate limits or authentication, but is sufficient for typical use.
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?
Description is only 3 sentences, front-loaded with the core purpose. Every sentence provides value without redundancy.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Even without an output schema, the description names the return fields and links to the next logical action (respond_rfq). Pagination is explained, and the tool's role in the workflow is clear.
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?
Schema coverage is 100% with well-described parameters (page and pageSize). Description does not add additional meaning beyond the schema, so baseline score of 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?
Clearly states 'List currently open (ACTIVE) RFQs' with specific verb and resource. Distinguishes from siblings like list_my_trades and respond_rfq by mentioning when each should be used.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines5/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
Explicitly provides use cases: 'USE WHEN: acting as a market-maker agent deciding what to quote on... DO NOT USE WHEN: you want your own trade history (use list_my_trades).' Also directs to respond_rfq for quoting.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior5/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Discloses read-only nature and safety to call anytime. Explains empty array behavior for unknown tradeId (not an error), and details the structure and interpretation of the result array. Since no annotations exist, the description carries the full burden and excels.
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?
Well-structured into sections (purpose, returns, usage, interpretation). Some verbosity in the interpretation section, but every sentence adds value. Front-loaded key info effectively.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Highly complete: covers purpose, return format, edge cases, interpretation per leg, and usage guidance. Despite no output schema, the description compensates thoroughly for a one-parameter query tool.
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?
Schema coverage is 100% with a clear description for tradeId. The description repeats the empty-array behavior already in the schema, adding no new parameter-level meaning. Thus 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?
Clearly specifies 'Real-time trade observability — per-leg HTLC settlement state for a trade' with specific details on what is returned. Distinguishes from sibling tools like list_my_trades and list_open_rfqs by stating it covers settlement-leg state only.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines5/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
Provides explicit 'USE WHEN' scenarios (showing trade status, deciding next action, polling) and a 'DO NOT USE WHEN' section naming alternative tools, guiding appropriate invocation.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Discloses read-only nature and no auth side effects. Explains that same symbol on different chains are distinct markets, which is a behavioral trait beyond basic description. No rate limits or pagination mentioned, but acceptable for a simple list with no parameters.
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?
Three paragraphs with clear front-loaded first sentence. Each sentence adds value, though could be slightly more concise by merging some lines. Overall well-structured.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Complete context for a parameterless list tool: explains entry format (SYMBOL/chain), usage hints, and distinctions between chains. No output schema needed as purpose is clear.
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 in schema, so description does not need to add parameter info. Schema coverage is 100% (no params). Baseline 4 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?
Description clearly states the tool lists chain-qualified token pairs supported for RFQ/swap. The use of specific verb 'list' and resource 'token pairs' sets a precise scope, distinguishing it from siblings like create_rfq or swap_quote.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines5/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
Explicitly provides when to use ('before create_rfq if unsure a token/chain is supported', 'to show available markets') and when not to use ('if already know the pair is supported'), including the rationale that this is for discovery, not a precondition.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Without annotations, the description carries full behavioral burden. It explains the refund mechanism (non-custodial, trustless, no preimage needed) and conditions. However, it omits details on idempotency or success/failure behavior beyond the parameter note for client_request_id.
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?

Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no output schema and moderate parameter count, the description covers usage context, parameter semantics, and behavioral intent. It lacks error scenarios or return value details, but is sufficient for an agent to invoke correctly in the stated conditions.
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?
Schema coverage is 100% (baseline 3). Description adds value by clarifying that 'txHash' is on-chain 0x-prefixed and that 'chainType' should be 'bitcoin' or 'sui' for non-EVM legs, which is not obvious from the schema alone. Also explains 'client_request_id' as an idempotency key.
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 tool's purpose: 'Trustless unwind — recover locked funds after the HTLC timelock expires.' It distinguishes from sibling 'withdraw_htlc' by specifying when NOT to use it, providing a specific verb-resource pair and scope.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines5/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
Explicit 'USE WHEN' and 'DO NOT USE WHEN' sections with concrete conditions (timelock deadline passed, counterparty didn't lock) and an alternative tool named (withdraw_htlc). Also notes that only the original lock sender can call refund, and only after deadline.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Reveals that revealing the preimage makes the swap atomic and simultaneously unlocks the counterparty leg. Lacks mention of irrevocability or on-chain txHash requirement, but sufficient for the operation.
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?
Compact description with clear structure: one-line summary, use/don't-use section, and param notes. Every sentence provides necessary information.

Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Covers purpose, usage, and key parameters adequately. No output schema, but for a claim operation, missing return value info is acceptable given the straightforward nature.
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?
Schema coverage is 100%, so baseline is 3. Adds value by specifying preimage format (0x-prefixed 32-byte hex) and chainType for non-EVM legs beyond schema descriptions.
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?
Clearly describes the tool as an atomic claim that reveals the preimage to unlock both legs. Distinguishes from sibling 'refund_htlc' by mentioning timelock expiry.

Usage Guidelines5/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
Explicitly states when to use and when not to use, including a specific alternative tool (refund_htlc) for expired timelocks.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior5/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description fully discloses behavioral aspects: sealed-bid auction, non-custodial nature, cross-chain support, zero slippage, and pre-call steps. It also covers idempotency and the requirement to confirm before calling, ensuring the agent understands the tool's behavior comprehensively.
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 well-structured with clear headings, examples, and logical flow. It is detailed but every section adds essential information for proper tool usage. The front-loading of the core purpose and the use of tables and examples make it efficient for an AI agent to parse.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Despite the detailed description, it lacks an explanation of the tool's return value. There is no output schema, and the description does not mention what the response contains (e.g., RFQ ID, status). For a complex tool with no output schema, this omission creates a completeness gap, though the rest of the context is thorough.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters5/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Despite no output schema, the description covers return value (trade_id) and next step (create_htlc). It also addresses edge cases (missing parameters, size exceeding request) and constraints (non-custodial). Fully sufficient for an agent to use correctly.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters5/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema has 100% coverage with descriptions. The description adds significant meaning: limit_price is sealed reservation and must be re-supplied, quote_id is exact bid from swap_status, client_request_id is idempotency key. This goes beyond the schema's basic descriptions.
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?
Clearly states it accepts the winning sealed bid and creates a trade, differentiating from sibling tools like respond_rfq. The verb 'accept' and resource 'swap' are specific, and the description distinguishes from maker-side quoting.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines5/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
Explicitly provides USE WHEN (swap has acceptable bid and user confirmed) and DO NOT USE WHEN (price not surfaced or want maker-side quoting), with alternative tool named (respond_rfq). This gives clear decision criteria.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
