Server Quality Checklist

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

Latest release: v0.2.0
Disambiguation4/5
The 45 tools cover distinct actions across agents, offers, needs, deals, payments, disputes, webhooks, and fulfillment. While some actions like close_deal and confirm_delivery could be confused conceptually, their descriptions clearly differentiate them. Overall, each tool has a unique purpose.
Naming Consistency5/5
All tools use the 'agentpact.' prefix and follow a consistent verb_noun pattern in snake_case (e.g., accept_deal, search_offers, register_webhook). This makes the tool set predictable and easy to navigate.
Tool Count3/5
With 45 tools, the set is large but covers a comprehensive marketplace workflow. While it exceeds the typical 'well-scoped' range, the number is justified by the breadth of functionality including payments, disputes, and webhooks.
Completeness5/5
The tool set covers the full lifecycle: registration, listing (offers/needs), discovery, negotiation, payment, fulfillment, dispute resolution, and reputation management. There are no obvious gaps for a marketplace platform.
Average 4.1/5 across 45 of 45 tools scored. Lowest: 3.4/5.

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

Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations indicate readOnlyHint=false and destructiveHint=false, but the description adds little beyond the obvious create action. No information is given about idempotency, uniqueness constraints, side effects, or required permissions, which are important for a mutation tool.
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 two sentences, front-loaded with the core action, and every sentence adds value. There is no redundant or wasted 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?
Despite the lack of an output schema, the description explicitly states that the tool returns the created offer object with its unique ID. The parameter list is fully covered by the schema. The description is sufficient for a create tool, though it could note the required apiKey.
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 description coverage is 100%, so the schema already explains each parameter. The description does not add new semantic meaning beyond the schema. Baseline 3 is appropriate as the definition adds marginal value.
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 verb 'create', the resource 'public offer listing', and the context of the AgentPact marketplace. It also explains the purpose of advertising a service and mentions discoverability and deal proposals, fully distinguishing it from sibling tools like create_need.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides no guidance on when to use this tool versus alternatives such as update_offer or create_need. It does not mention exclusion criteria, prerequisites, or specific scenarios, leaving the agent without context for tool selection.
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?
Annotations provide minimal information (readOnlyHint: false, destructiveHint: false). The description adds behavioral context by stating that accepted fulfillment becomes active and rejected returns to pending. It does not mention additional effects like the completeOnVerify parameter or potential idempotency.
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 (one sentence) and front-loaded with the role. It conveys essential information without excess, though it could be better structured with separate sentences for clarity.
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?
The description covers core action and outcomes but omits return values (no output schema), error conditions, prerequisites, and parameter details beyond what the schema provides. For a state-changing tool with 6 parameters, it is adequate but not fully comprehensive.
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%, so all parameters have descriptions in the input schema. The tool description adds little beyond that, only reinforcing the buyer role. With high schema coverage, the baseline is 3; the description does not provide significant extra meaning.
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 the tool's purpose ('verify whether provided fulfillment details are valid') and specifies the resource (fulfillment). It implicitly differentiates from siblings by indicating it is the buyer's action, but does not explicitly mention alternatives like verify_delivery or confirm_funding.
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 identifies the role ('As the buyer') and explains outcomes of accept/reject. However, it lacks explicit guidance on when to use this tool versus alternatives (e.g., verify_delivery, confirm_funding) and does not mention when not to use it.
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?
Description adds some behavioral context beyond annotations: mentions defaults (20% price flexibility, generic fulfillment) and that it returns an offer object with next-step instructions. Annotations already indicate write-only. Does not disclose rate limits, auth needs beyond API key, or side effects like irreversible changes.
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 a single sentence, front-loaded with the key action and resource, and contains no redundant words. Every part is valuable.
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?
For a shortcut tool, the description covers creation, defaults, and next-step instructions. However, it does not mention error conditions, customization options, or if the operation is reversible. Lacks some completeness for edge cases.
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%, so parameters are already well-documented. The description does not add additional meaning beyond summarizing the tool's overall behavior. 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?
The description clearly states the tool's purpose: 'One-call shortcut to list a service for sale' and specifies it 'creates an offer with paid defaults (20% price flexibility, generic fulfillment).' This distinguishes it from siblings like `create_offer` and `quick_buy`.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description does not provide explicit guidance on when to use this tool versus alternatives like `create_offer`. It only implies it's a 'shortcut' but lacks context on when to choose it or when not to use it.
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?
Annotations indicate non-read-only and non-destructive. Description mentions encryption at rest, adding security context. However, no side effects, return values, or post-submission behavior are disclosed. Annotations already cover basic mutability, so description adds moderate value.
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?
Two sentences, front-loaded with purpose and role, second sentence adds essential security note. No filler or redundancy.
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?
Lacks description of return value or effect on deal lifecycle. With 4 parameters, nested objects, and no output schema, a bit more context on what happens after submission would improve completeness. Acceptable for a data submission 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%, but description provides additional context: buyerData examples (service date, address, access notes, contact method) and apiKey origin (from agentpact.register). This adds meaning beyond schema descriptions, which are generic.
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 is for submitting private context as a buyer for deal fulfillment, with examples like address or access notes. Distinguishes from sibling tools which have different roles (e.g., provide_fulfillment likely for sellers).
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No explicit guidance on when to use this tool versus alternatives like provide_fulfillment or other context tools. The description implies usage only for buyers but does not set conditions or exclusions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already indicate non-read-only and non-destructive. Description adds 'buyer will verify and accept or reject' but no additional behavioral traits like state changes, retries, or side effects. Minimal value beyond 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?
Two concise sentences. First defines action and role, second explains post-submission process. No redundant words. Front-loaded and efficient.
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?
Covers basic flow but misses contextual details like required authentication via apiKey (mentioned only in schema), state ownership, or irreversibility. No output schema, but description partially compensates by describing buyer verification. Adequate for a submit action but has gaps.
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% with descriptions for all 5 parameters. Description adds value by clarifying artifact types ('URLs, files, API endpoints') beyond the schema's generic examples. Also hints that notes are optional. Baseline 3, plus extra context justifies 4.
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 the verb 'submit delivery artifacts' and the resource 'for a funded milestone as the seller'. Distinguishes from siblings like 'confirm_delivery' and 'verify_delivery' by specifying the seller's role and artifact types (URLs, files, API endpoints). No ambiguity.
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?
Mentions context 'after milestone is funded' and roles (seller submits, buyer verifies). However, lacks explicit when-not-to-use or alternative tools for similar actions (e.g., resubmission, cancellation). No direct comparison with siblings.
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?
Annotations already indicate non-read-only and non-destructive behavior. The description adds that acceptance transitions the status and restricts to parties, but lacks details on side effects like irrevocability or error states.
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 two sentences, front-loaded with the action, and every sentence adds value with no wasted words.
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?
The description covers purpose and a key usage constraint, but with no output schema, it omits return values or conditions for failure (e.g., deal not in correct state). Adequate but not fully comprehensive for a state-changing 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%, so the baseline is 3. The description does not add extra meaning to parameters beyond what the schema provides.
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 accepts a deal and transitions it to 'accepted' status, with a specific verb and resource. It distinguishes from sibling tools like propose_deal or counter_deal.
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 provides a clear usage constraint ('Only a party to the deal may accept it') but does not explicitly guide when to use this tool versus alternatives like countering or canceling.
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?
Annotations already indicate non-read-only and non-destructive. The description adds that the tool performs on-chain verification and transitions the milestone to 'funded' status, which is useful behavioral context 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.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences, no wasted words. First sentence states the action, second sentence explains the effect. Efficient and front-loaded.
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 is provided, and the description does not explain what the tool returns (e.g., success indication, updated intent). It mentions the milestone transition but omits response details. For an on-chain verification tool, this is a significant 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?
Schema coverage is 100% with descriptions for all 3 parameters. The description adds context about the workflow but does not provide additional semantic detail beyond what is in the schema (e.g., txHash format is already specified). 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 verb (confirm), resource (payment intent), and action (providing transaction hash for on-chain verification). It distinguishes from siblings like confirm_delivery or get_payment_status by specifying the exact step in the funding flow.
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 implies when to use (after sending USDC on-chain) but does not explicitly state when not to use it or provide alternatives among the many sibling tools. The context of sibling names suggests other confirmation tools exist, but no guidance is given.
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?
Annotations indicate readOnlyHint=false and destructiveHint=false, so the description adds the role context ('as the buyer') but does not elaborate on side effects like whether notifications are sent or if confirmation is needed. This is adequate but minimal 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.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single sentence that conveys the essential information without any wasted words. It is front-loaded and efficient.
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?
With 4 parameters, no output schema, and a simple action, the description covers the basic action and role. However, it omits details about post-request steps (e.g., notification to seller) and prerequisites beyond being a buyer, leaving the agent with some uncertainty.
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 4 parameters are described in the input schema with 100% coverage. The description does not add any parameter-level meaning, so it meets the baseline for schema-covered tools.
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 verb 'request' and the resource 'rotate fulfillment credentials', explicitly noting the buyer role. It distinguishes itself from the sibling tool 'agentpact.rotate_credential' which likely performs the actual rotation, making the purpose 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?
The description provides clear context that this tool is for buyers to request credential rotation from sellers. It does not explicitly exclude alternative tools or state when not to use, but the context is sufficient for an informed agent.
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?
Annotations already indicate destructiveness. Description adds context about encryption and deal fulfillment, but does not detail exact effects (e.g., old credential invalidation).
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

Single sentence, no filler. Efficiently conveys essential information.
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?
Missing output description and prerequisites (e.g., active deal, seller ownership). Adequate but could be more comprehensive.
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 covers 100% of parameters with descriptions; description adds no extra parameter details beyond what's in schema.
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 verb 'rotate', resource 'encrypted credential field', and role 'seller'. Distinguishes from sibling 'request_rotation' (request vs. perform).
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?

Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations indicate readOnlyHint=false and destructiveHint=false, so the description confirms modification and returns updated deal. It adds context about the price bound but does not disclose additional behavioral traits like rate limits or auth specifics.
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?
Two sentences, no wasted words. Front-loaded with the action and noun, followed by constraint and output. Efficient and structured.
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?
For a 5-parameter tool with no output schema, description covers purpose, constraint, return value, and parameter details. Could mention error cases or maxPriceDeltaPct definition, but overall sufficient without major gaps.
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 negotiatedTotal must be within maxPriceDeltaPct and milestones have revised amounts/titles/deadlines, going beyond the 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?
Description clearly states the tool submits a counter-offer on an existing deal, adjusting total/milestones. Verb 'submit' and resource 'counter-offer' are specific, distinguishing it from siblings like accept_deal or propose_deal.
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?

Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already indicate the tool is not read-only and not destructive. The description adds that the deal is created and returned, and mentions the initial status. However, it does not disclose other behavioral traits such as idempotency, authentication needs, or rate limits.
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 consists of three succinct sentences, each adding value. The first sentence states the purpose and participants, the second gives lifecycle context, and the third mentions the return value. No fluff.
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 8 parameters, no output schema, and no nested objects, the description adequately covers the tool's purpose, lifecycle, and return value. It lacks details on error conditions or prerequisites, but it is sufficiently complete for a creation 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 description coverage is 100%, so the baseline is 3. The description reinforces the role of key parameters (offerId, needId, negotiatedTotal, milestones) by stating the deal links an offer to a need with a negotiated price and milestone schedule, but does not add new meaning beyond the 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 the verb (Propose), resource (deal), and participants (buyer and seller agent). It distinguishes from sibling tools by specifying the initial creation of a deal linking an offer to a need with a negotiated price and milestones.
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 provides lifecycle context: the deal starts in 'proposed' status and the counterparty can accept, counter, or cancel. While not explicitly stating when to use this vs alternatives, it implies this is the initial proposal step, and sibling names (accept_deal, counter_deal) reinforce the distinction.
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?
The description discloses that the tool creates a need and proposes a deal, which is a creative/mutating operation. It also mentions the return value includes next-step instructions. No contradiction with annotations (readOnlyHint=false, destructiveHint=false).
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 a single sentence that is concise and front-loaded with the purpose. It could be slightly expanded with a brief note on required inputs, but it is not overly long.
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 the tool's complexity (combined creation and proposal) and no output schema, the description covers the basic purpose and return value but lacks details like prerequisites (e.g., valid offer and agent IDs) or state implications of the created need.
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%, so the schema already documents each parameter. The description does not add additional meaning beyond what is in the schema, meeting the baseline for high coverage.
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 it is a shortcut to buy an offer by creating a need and proposing a deal. It uses specific verbs and resources, and distinguishes itself from sibling tools like create_need, propose_deal, and quick_sell.
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 the tool is for quick purchase when you want to combine multiple steps. However, it does not explicitly state when to avoid it (e.g., if more customization is needed) or mention alternatives like creating a need and proposing a deal separately.
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?
Annotations already provide destructiveHint: true, and description confirms revocation. No additional behavioral context beyond what annotations convey.
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?
Single sentence with no waste, front-loads the action and example use case.
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?
Sufficient for a simple revocation tool with annotations; could mention post-revocation state but not necessary for basic usage.
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 covers 100% of parameters with clear descriptions. The description adds no extra meaning beyond the schema.
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 uses specific verb 'revoke' and resource 'fulfillment access for a deal', clearly distinguishing from sibling tools like provide_fulfillment or verify_fulfillment.
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?
Mentions 'As the seller' and example reasons 'after completion or expiry', but does not explicitly state when not to use or list alternative tools.
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?
Annotations already indicate readOnlyHint=true, so the description's addition of pagination and relevance sorting adds some behavioral context. However, it does not detail pagination mechanisms or authentication requirements beyond the schema. Given annotation coverage, this is adequate but not exceptional.
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 two sentences: first describing the function, second providing usage guidance. It is front-loaded, concise, and every sentence adds value without redundancy.
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?
For a search tool with no output schema, the description mentions pagination and relevance sorting, which are key behavioral aspects. It lacks detail on the structure of returned offers, but given the simple nature of the tool and presence of usage guidance, it is largely complete.
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 description coverage is 100%, with each parameter already documented. The description summarizes filter criteria but adds no new meaning beyond the schema. Baseline of 3 is appropriate as the description is not needed to clarify parameters.
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 searches for offers in the marketplace using query, tags, and price range. It distinguishes from sibling tools like search_needs by focusing on offers and mentioning discovering services for purchase or deals.
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 provides a clear usage context ('discover services your agent can purchase or propose deals against') but does not explicitly state when not to use it or mention alternatives like search_needs. The guidance is helpful but lacks exclusion criteria.
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?
Annotations only provide readOnlyHint and destructiveHint (false). Description adds that alerts are delivered via webhook, which is useful. However, it does not discuss subscription persistence, unsubscription, or requirement for an API key (though param describes it). Adequate but not detailed.
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?
Two sentences, concise, front-loaded with purpose. No redundant 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?
For a subscription tool with 5 parameters and no output schema, the description covers the core use case. Missing details on response format (e.g., subscription ID) but not critical for selection.
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 description coverage is 100%, so the baseline is 3. The description does not add new parameter information beyond what is in the schema.
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 subscribes to real-time alerts for new offers/needs, specifies webhook delivery, and contrasts with polling. This differentiates it from search tools among siblings.
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 says to use for proactive discovery without polling, implying when to use. Does not explicitly mention alternatives or when not to use, but context with sibling search tools is clear.
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?
Adds partial update behavior and non-archive condition beyond annotations. However, lacks details on idempotency, authorization (beyond apiKey param), or return value. Annotations already indicate non-read-only and non-destructive, so description provides some additional context.
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?
Two sentences, front-loaded with purpose and examples, then constraints. No unnecessary words. Every sentence adds value.
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?
Covers purpose, ownership, partial update, non-archive condition, and lists editable fields. Minor gap: no mention of return value (no output schema), but otherwise adequate for a simple mutation 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%, so description adds little beyond listing example fields (title, description, tags). The partial update clarification is useful but not per-parameter. Baseline 3 applies.
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 verb 'update' and resource 'need' with ownership constraint. Distinguishes from siblings like archive_need and update_offer by specifying scope and condition.
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?
Provides clear context: partial update of owned need, must not be archived. Implicitly distinguishes from create_need and archive_need, though no explicit alternatives or when-not-to-use are stated.
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?
Annotations (readOnlyHint=false, destructiveHint=false) indicate mutation but no destruction. The description adds behavioral context: accepting triggers payment release; rejecting allows resubmit or dispute. This goes beyond annotations, though it omits details like reversibility or authorization needs. For a tool with minimal annotations, this is solid.
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 two tight sentences that front-load the core action and consequences. No redundant or extraneous information; 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?
For a tool with 5 parameters, no output schema, and no nested objects, the description covers the essential purpose and outcomes. It does not mention error handling or return values, but the input schema is fully described. Overall, it is adequately complete for this complexity level.
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 clear descriptions for all parameters. The description does not add significant meaning beyond the schema (e.g., it restates that 'accepted' triggers payment). Baseline 3 is appropriate since the schema carries the burden.
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: 'As the buyer, verify a submitted delivery and either accept or reject it.' It specifies the verb (verify) and resource (delivery), and distinguishes from siblings like submit_delivery and confirm_delivery by focusing on the buyer's verification action. The consequences (payment release, resubmit, dispute) add clarity.
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 implies usage when a delivery is submitted and the buyer must accept or reject, but it does not explicitly contrast with related sibling tools like agentpact.confirm_delivery or agentpact.verify_fulfillment. It lacks 'when to use this vs. alternatives' guidance, leaving the agent to infer context.
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?
Annotations already declare readOnlyHint=true and destructiveHint=false, so the safe, read-only nature is clear. The description adds behavioral context by specifying that the output includes 'physical-service for two-sided on-site workflows', going beyond what annotations provide.
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 consists of two sentences with no wasted words. The main action is front-loaded, and every 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?
The description explains the tool's purpose and output content but lacks detail on the output structure (e.g., whether it returns an array of objects or a map). Since there is no output schema, the description should ideally provide more structural guidance. Still, it covers the core intent adequately.
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 description coverage is 100% (apiKey parameter is fully described in the schema). The description does not add any extra meaning about the parameter beyond what the schema already provides, so baseline score of 3 applies.
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 lists all supported fulfillment template types and their fields, using a specific verb ('List') and resource ('fulfillment template types'). It distinguishes from sibling tools like agentpact.get_fulfillment (which retrieves a single fulfillment) and agentpact.provide_fulfillment (which creates one).
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 explicitly tells when to use this tool: 'Use this before providing deal fulfillment details so payloads match the required schema.' It provides clear context but does not explicitly exclude alternative tools or mention when not to use it.
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?
Adds context beyond annotations: prevents milestones, eligible refunds, audit reason. Contradiction: false.

Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, so the description doesn't need to add much parameter detail. It provides context about valid deal statuses but no additional meaning beyond the schema. 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 the tool closes a deal in one call, marking it completed, releasing payment, and updating trust scores. It distinguishes itself from the multi-step confirm-delivery flow, making its purpose distinct from siblings like confirm_delivery and cancel_deal.
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 says to use this instead of the multi-step confirm-delivery flow, and specifies it works on deals in 'active', 'delivered', or 'proposed' status. Also mentions auto-completion fallback. Lacks explicit 'when-not-to-use' but the context is clear enough.
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?
Describes the side effects: completes deal, releases payment, updates trust scores. No contradiction with annotations (readOnlyHint=false, destructiveHint=false). The description adds meaningful behavioral context 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.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences: first states purpose and effects, second gives usage guidance. No wasted words, highly efficient and 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?
Covers purpose, side effects, and when to use. Given 5 parameters and no output schema, the description is sufficient. Could mention failure scenarios but not necessary for basic completeness.
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%, so baseline 3. The description implies the buyer's role but does not add significant meaning beyond what the schema already provides for parameters like dealId, agentId, notes, and rating.
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?

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?
Annotations already declare readOnlyHint=true and destructiveHint=false. The description adds useful behavioral context by listing the types of information returned (reputation, trust tier, deal history stats, wallet info). No contradictions.
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?
Two sentences with zero waste. First sentence states purpose and return fields. Second sentence gives usage guidance. Front-loaded with the most critical 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 tool's simplicity (2 parameters, no output schema), the description is complete. It explains what the tool returns (specific fields) and when to use it. Annotations cover safety. No gaps are evident.
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 adequate descriptions for both parameters (id, apiKey). The description reinforces the id parameter as 'by its ID' and mentions apiKey as 'your API key', but does not add significant new meaning beyond the schema. 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 tool retrieves an agent's full profile by ID, listing specific fields (reputation, trust tier, deal history, wallet). It distinguishes from 35+ sibling tools as the only 'get_agent' tool, and provides usage context (inspect before deal or check own profile).
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 explicitly advises when to use the tool ('inspect any agent before proposing a deal or to check your own profile'). It does not mention exclusions or alternatives, but the read-only nature is clear and no sibling duplicates the function.
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?
Annotations already declare readOnlyHint=true. Description adds access restriction (buyer/seller only), providing useful behavioral context beyond 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?
Two sentences, no wasted words. Front-loaded with purpose and access constraint.
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?
Adequate for a simple read tool with annotations. Missing details about return value, but tool name implies fulfillment object. No output schema, so some inference needed.
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 good parameter descriptions. Description does not add new semantic details beyond reinforcing the access condition, which is already in schema for agentId. 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?
Description clearly states 'Get fulfillment details and current fulfillment status for a deal', a specific read operation. It distinguishes from sibling tools like provide_fulfillment or revoke_fulfillment which are write operations.
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?
Includes access constraint: 'Only the buyer or seller party can access this data'. Provides clear context but no explicit when-not-to-use or alternatives.
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?
Annotations indicate readOnlyHint=true and destructiveHint=false, which are consistent with the description. The description adds behavioral context by stating the returned payment state, amounts, and on-chain transaction details, as well as the requirement that at least one identifier be provided.
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. It front-loads the purpose, lists key outputs, and ends with a critical constraint. Every sentence carries necessary 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?
For a read-only tool with 3 parameters and annotations covering safety, the description is fairly complete. It explains the return values and the parameter requirement. It does not cover error cases (e.g., when an ID is not found), but this is a minor omission given no output schema.
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%, so baseline is 3. The description reiterates the parameter descriptions from the schema (apiKey, milestoneId, paymentIntentId) and adds the constraint that at least one of milestoneId or paymentIntentId must be provided. This adds marginal value beyond the schema.
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 checks the status of a USDC payment using milestone ID or payment intent ID, listing the returned fields (state, amounts, transaction details). It distinguishes itself from sibling tools like release_payment or request_refund by being a read-only status check.
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 check payment status before performing mutations) and specifies that at least one parameter must be provided. However, it does not explicitly list when not to use it or name alternative tools, but the context from sibling names provides clear differentiation.
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?
Annotations already declare readOnlyHint=true and destructiveHint=false. Description adds what is returned (composite score, trust tier, total deals, rating averages), complementing annotations without contradiction.
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?
Two sentences, front-loaded with action and result. No unnecessary words, efficient and clear.
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?
For a simple read-only tool with two parameters and no output schema, the description covers purpose, use case, and returned data. Missing details like error cases, but adequate given annotations.
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 descriptions for both parameters. Description does not add new meaning beyond schema, so 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?
Description uses specific verb 'retrieve' and resource 'reputation snapshot', distinguishing it from siblings that deal with deals, needs, offers, etc. No other tool retrieves reputation.
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?
States use case 'assess an agent's reliability before proposing a deal', providing clear context. No explicit exclusion or alternative, but reputation tool is unique among siblings.
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?
The description adds value beyond annotations by mentioning that feedback updates the target agent's reputation score and trust tier, and that only one feedback per deal is allowed. Annotations only indicate it's not read-only and not destructive.
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 remarkably concise, consisting of two sentences that pack all essential information without any redundant or irrelevant content.
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 complexity (9 parameters, no output schema), the description covers key aspects: purpose, timing, constraint, and effect on reputation. It does not detail return values or error handling, which is acceptable without an output schema.
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 description coverage is 100%, so the baseline is 3. The description redundantly mentions the four rating dimensions and their 1-5 scale, which is already in the schema. It adds no significant new parameter semantics.
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: leaving feedback for another agent after a completed deal, rating four specific dimensions. This is distinct from sibling tools that handle deal creation, acceptance, etc.
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 specifies when to use the tool: 'after a completed deal.' It also notes the constraint of one feedback per deal. However, it does not explicitly state when not to use it or suggest alternatives.

Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already indicate it is a write (readOnlyHint=false) and non-destructive (destructiveHint=false) operation. The description adds useful behavioral details: a 7-day resolution timeout, expectation to provide evidence, and the return of a dispute object with ID and deadline. No contradiction.
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, front-loaded with the core purpose. Each sentence adds essential information (purpose, timeout, evidence, return). No redundant or missing parts.
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 output schema, the description mentions the return value (dispute object with ID and deadline). It covers key behavioral aspects. It lacks explicit prerequisites (e.g., being a party to the deal is in param description only) but overall is complete for a dispute opening 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 description coverage is 100%, so the schema already documents all parameters adequately. The description does not add any additional meaning or examples beyond what the schema provides. 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?
The description uses specific verbs and resources: 'Open a formal dispute on a deal milestone'. It clearly distinguishes from sibling tools like 'cancel_deal' or 'confirm_delivery' by focusing on the dispute scenario.
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 provides a clear trigger condition: 'when buyer and seller cannot agree on delivery or payment'. It implies usage but does not explicitly mention alternatives or when not to use it, which is a minor gap.
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?
Adds value beyond annotations by disclosing the 10% platform fee, seller receives 90%, and the prerequisite. Annotations indicate non-readOnly (mutation) and non-destructive, which the description confirms. Lacks details on idempotency or response format.
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?
Two sentences, front-loaded with action and fee, then condition. No unnecessary words. Efficient and clear.
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?
Covers purpose, precondition, and a key behavioral detail (fee split). Missing output schema description; an inference about return value (e.g., success/failure) would enhance completeness. Overall adequate 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?
Schema coverage is 100% with descriptions for both parameters. The description does not add additional parameter-level meaning beyond what is in the schema. Baseline 3 is appropriate.

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 states the precondition: 'should be called after the buyer has verified and accepted the delivery.' This guides when to use, though it does not explicitly mention when not to use or alternative tools.
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?
Annotations already set destructiveHint=true, so the description is not required to reiterate state changes. It adds value by explaining the specific conditions for refunds (delivery failure or dispute resolution), which aids appropriate invocation. It does not cover potential side effects on related entities (e.g., deal status) or discuss authentication needs beyond the schema.
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 extremely concise with two sentences: first stating the action and outcome, second providing usage context. No extraneous words or redundancy; every sentence serves a purpose.
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?
The description covers the tool's purpose and typical usage scenarios. It could be improved by mentioning prerequisites (e.g., the payment must be funded) or noting that it is a buyer-initiated action. However, given the lack of output schema and simple parameter set, it is largely sufficient.
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?
With 100% schema description coverage, all three parameters are already documented. The description does not add any additional semantic guidance (e.g., format or example values). It simply restates the overall action, so it meets the baseline without extra value.

Is the description appropriately sized, front-loaded, and free of redundancy?
The description is two sentences, front-loads the action and content, and contains no unnecessary words. Every sentence provides value.
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?
For a parameterless read-only tool with no output schema, the description sufficiently explains what data is returned (list of statistics). No additional context is needed.
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?
The input schema has zero parameters, so schema description coverage is 100%. The description adds no parameter details but is not needed. Per guidelines, 0 parameters yields a baseline of 4.
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 verb 'Get', the resource 'public overview of the AgentPact marketplace', and lists specific aggregate statistics (active offers, open needs, live deals, total registered agents). This provides a specific purpose that distinguishes it from sibling tools like create_agent or search_offers.
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 explicitly states 'No authentication required' and 'Useful for monitoring marketplace health', giving clear usage context. However, it does not explicitly mention when not to use or provide alternative tools for more detailed data, but the aggregate nature implicitly differentiates.
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?
Annotations indicate readOnlyHint=false and destructiveHint=false, which are consistent with registration. The description adds behavioral context: it returns an API key, requires a valid UUID, and that this key is needed for authenticated operations. This goes beyond annotations by clarifying the tool's role and prerequisites.
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 succinct sentences with no waste. The purpose is front-loaded, and every sentence adds essential information (purpose, importance, prerequisites).
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?
Given the simplicity of the tool (register and get API key) and the absence of an output schema, the description adequately covers the return value (API key) and its necessity. The context of being the first step is sufficient for an agent to understand how to proceed.
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% with descriptions for both parameters. The description adds meaning by stating 'agent ID must be a valid UUID' (reinforcing format) and explaining wallet address is 'used for USDC payments on Base', which provides context beyond the schema.
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 'Register a new agent on the AgentPact marketplace and receive an API key.' It uses a specific verb ('register') and resource ('agent on marketplace'), and distinguishes from sibling tools by being the initial registration step.
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 explicitly says 'This is the first step for any agent — the returned API key is required for all authenticated operations.' This provides clear context for when to use the tool, though it does not explicitly list when not to use it or alternatives. Given siblings are all subsequent operations, it's clear it's a prerequisite.
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?
Annotations indicate it's not read-only or destructive. The description adds that payloads are HMAC-signed and returns webhook ID/secret. No contradiction, but could mention resource creation 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?
Two sentences, every word adds value. Front-loaded with purpose and key details. No superfluous information.
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?
Covers all essential aspects: purpose, event types, signing, output (ID and secret). No output schema but description compensates. Complete for its complexity.
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 has 100% coverage. Description adds value by specifying HTTPS requirement, 'webhook.test' usage, and auto-generated secret. Adds meaning beyond schema.
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 the tool registers a webhook endpoint for real-time event notifications. Distinguishes from siblings like delete_webhook and list_webhooks.
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?
Describes when to use (subscribe to specific events) and mentions using 'webhook.test' for verification. Could be more explicit about prerequisites like having an API key, but overall clear.
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?
Describes permanent deletion and cessation of notifications, aligning with destructiveHint annotation. No contradictions.
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: action, prerequisite, consequence. No 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?
For a simple deletion tool with two parameters and clear annotations, the description provides all necessary context: purpose, usage, and irreversibility.
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 covers both parameters fully (100% coverage), and description only repeats schema info (e.g., ID from list_webhooks). No additional parameter meaning beyond schema.
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 deletes a webhook by ID and stops notifications, distinguishing it from webhook listing or registration tools.
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 instructs to use agentpact.list_webhooks to find the ID and emphasizes irreversibility, guiding appropriate use.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
