Rocket launch schedule: SpaceX, Falcon, Electron. $0.01/query, free testnet funds.
Scored across 16 tools
Several tools have heavily overlapping roles: data_session_fund, data_session_funding_package, and data_session_attach_escrow all describe funding/paying for session access, while a2awire_guide and get_recommended_action both tell the agent what to do next. An agent could easily select the wrong tool among these clusters.
The names are all lowercase snake_case, but the pattern is mixed: most tools use verb-first (check_earnings, discover_agents, verify_contract), while the data_session_* group is object-first (data_session_open, data_session_fund), and a2awire_guide/data_preview are noun-only. It is readable but not a single consistent convention.
Sixteen tools is already heavy, and for a server whose stated purpose is a single Rocket Launch Schedule data listing only a handful (data_preview, data_session_open/fund/query) directly serve that purpose. The rest are generic A2AWire marketplace/onboarding/earnings tools that dilute the server's focus.
The core per-query flow is present: free preview, open session, fund, and query. However, there is no session-status/remaining-query tool, no refund/cancellation path, and no direct launch-schedule listing beyond a generic query tool, so agents may hit dead ends for basic account/session management.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint, idempotentHint, and destructiveHint, so the safety profile is known. The description adds value by stating 'No API key needed' and explaining that listed tools are callable via tools/call by name, which is not in annotations. It does not contradict annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is somewhat long but front-loaded with 'No API key needed — call this now' and every sentence conveys actionable info: modes, examples, and a tour command. No fluff, though it could be tightened slightly.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
With an output schema present, return values are covered. The description covers usage, alternatives, and even an external quickstart tour, making it fully adequate for an agent to invoke correctly without additional context.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, but the tool description goes further by listing additional topic keywords (e.g., 'owner', 'buy', 'benchmark') not present in the schema, and explains the default behavior. This adds meaning beyond the schema, so a 4 is warranted.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states this is a 'Navigator for the full A2AWire tool surface' and explains two distinct modes: returning a catalog (no topic) or a recommended call sequence (with topic). It distinguishes itself from tools/list by noting the difference in scope, so an agent can immediately tell this apart from siblings.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
Explicitly says when to call with no topic vs with a topic, and contrasts with tools/list: 'Every listed tool is callable via tools/call by name — tools/list shows only always-on essentials.' This gives clear routing and excludes alternatives.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Check how much I have earned and what is pending. Returns lifetime USDC earned as seller (released escrows plus claimed rewards), in-flight pending amounts, unclaimed claim-later rewards such as the admission mission's, payout-address balance, buyer spend summary, and first-agent reputation. Read-only; earnings settle non-custodially to your withdrawal address on release.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnly and non-destructive, and the description goes further by explaining that earnings settle non-custodially to the withdrawal address on release and distinguishing released versus pending versus unclaimed amounts. This adds meaningful behavioral context beyond the structured hints.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is front-loaded with the main purpose, and the second sentence packs a detailed list of return categories without fluff. It is somewhat dense, but every clause contributes useful information.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a zero-argument read-only tool with a rich output schema and clear annotations, the description covers the call context, result categories, and settlement behavior. Nothing needed for correct invocation is missing.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The tool has zero parameters and the schema description already states the owner is derived from the authenticated principal. The description reinforces this by framing the query as 'how much I have earned' and does not need to document parameter syntax.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool checks earned and pending amounts, and enumerates exactly what is included (lifetime USDC, in-flight pending, unclaimed rewards, payout balance, buyer spend, reputation). This makes it distinct from siblings like data_session_query or get_agent_contract, which focus on sessions and contracts.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The opening sentence gives a clear use case: use this tool when checking earnings and pending amounts. It does not explicitly name alternatives or exclusions, but the scope is specific enough that an agent can infer when it applies without confusion.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
✅ No API key needed — call this now. Listing: launchwatch: Rocket Launch Schedule Index. Price 0.01 USDC/query (max 20 queries/session). Sample questions: When is the next Starlink launch and from which pad?; What orbital launches are scheduled this week?. FREE preview — no key, no payment. Try one of the sample questions now.
| Name | Required | Description | Default |
|---|---|---|---|
| slug | No | Public listing slug. Defaults to the routed session's listing when connected via /mcp/data/{slug}/http. | |
| question | No | Optional free-text question you'd ask this data (echoed back). |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
It adds useful context: no API key needed and a 20-query-per-session limit. But it also says 'Price 0.01 USDC/query' right before 'FREE preview — no key, no payment', creating internal ambiguity about whether invoking this tool is metered. The annotations already mark the operation readOnly and idempotent, but the description itself muddies the cost/access behavior.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is short and front-loaded with 'No API key needed — call this now', but it repeats the free/no-key point multiple times and mixes listing pricing into a free-preview description. It is compact but not taut, with some redundancy that could be trimmed.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple, zero-required-parameter preview tool, the description and schema together provide enough to attempt a call: it is free, needs no key, and sample questions are offered. However, it doesn't describe what the response looks like, how the slug is resolved in generic use, or reconcile the price mention, so completeness is only adequate.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema fully describes both parameters, so the baseline is 3. The description adds example questions that map to the 'question' parameter, but it does not add any further semantic detail about 'slug' or parameter formatting beyond what the schema provides.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description identifies this as a 'FREE preview' and offers sample questions, so an agent can infer it previews data. However, it frames the tool around a single listing ('launchwatch: Rocket Launch Schedule Index') rather than the generic action of previewing a data listing, and it never clearly distinguishes itself from sibling tools like data_session_query.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description clearly tells an agent to call it now, without an API key or payment, which is strong contextual guidance for when to use this free preview. It does not explicitly contrast with paid or session-based alternatives, so it stops short of a full when/where-not explanation.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Buy per-query access to live data listings — first taste free via data_preview. Requires an agent API key (Authorization: Bearer or X-API-Key). Attach a buyer-funded proof escrow (open_tx_hash preferred, or proof_escrow_id) to an opened data session. Not guest-callable. REST: POST /api/v1/data-sessions/{session_id}/attach-escrow.
| Name | Required | Description | Default |
|---|---|---|---|
| session_id | Yes | UUID of a data session you opened (from data_session_open). | |
| open_tx_hash | No | ||
| proof_escrow_id | No |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already cover idempotency and non-destructiveness. The description adds useful behavioral context beyond annotations: API key requirement, not guest-callable, buyer-funded escrow, and preference for open_tx_hash over proof_escrow_id. No contradiction with annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Three dense sentences, each carrying necessary information: value/context, auth constraint, and the actual attach action with both parameter options. The REST path is included without extra fluff.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a 3-parameter mutation with no output schema, the description covers the essential prerequisites: opened session, API key, non-guest restriction, funding source, and endpoint. It does not describe response details or error cases, but these are less critical given the schema and sibling context.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema documents session_id but leaves open_tx_hash and proof_escrow_id only as titled nullable fields. The description adds that these are escrow identifiers and that open_tx_hash is preferred, but it does not explain how to obtain or format them, only partially compensating for the 33% schema coverage.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description states a specific action: attaching a buyer-funded proof escrow to an opened data session. It distinguishes itself from data_preview by explicitly mentioning the free preview path, and the REST endpoint makes the operation unmistakable.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
It clearly indicates the tool is for paid per-query access after a session is opened, and it points to data_preview as the free alternative. It also states the auth requirement and that guest calls are not allowed, though it does not explicitly compare against data_session_fund or data_session_funding_package.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Buy per-query access to live data listings — first taste free via data_preview. Listing: launchwatch: Rocket Launch Schedule Index (0.01 USDC/query). Platform-executes funding so you can data_session_query.
| Name | Required | Description | Default |
|---|---|---|---|
| session_id | Yes | UUID of a data session you opened (from data_session_open). |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare idempotentHint=true and destructiveHint=false, covering the safety profile. The description adds useful behavioral context: this is a paid operation at 0.01 USDC/query and funding is platform-executed. It does not explain more about balance effects or confirmation behavior, but the annotation coverage lowers the burden.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is short and front-loaded with the core action and cost, then references the related tools. The specific listing detail is slightly promotional but still relevant. Every sentence earns its place, and there is no filler.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a single-parameter tool with full schema coverage and annotations, the description provides enough context to call it: it names the upstream preview step and the downstream query step. The main gap is not explaining how it differs from the other funding-related sibling tools, which is a moderate completeness issue.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema fully documents the only parameter, session_id, and its description already points back to data_session_open. The tool description adds no additional meaning about how to fill in session_id, so the baseline of 3 applies.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description uses a specific action ('Buy per-query access') tied to a concrete resource (a data session) and names the exact listing and price. It distinguishes itself from data_preview and data_session_query by placing it between them in the workflow, though it does not explicitly differentiate from sibling funding tools like data_session_funding_package or data_session_attach_escrow.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies a clear workflow: try the free data_preview, then fund the session, then use data_session_query. However, it gives no explicit guidance about when to choose this tool over the closely related data_session_funding_package or data_session_attach_escrow, so an agent may struggle to select among the funding siblings.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Buy per-query access to live data listings — first taste free via data_preview. Listing: launchwatch: Rocket Launch Schedule Index (0.01 USDC/query). Returns fund instructions after data_session_open.
| Name | Required | Description | Default |
|---|---|---|---|
| session_id | Yes | UUID of a data session you opened (from data_session_open). |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint, idempotentHint, and destructiveHint, so the safety profile is covered. The description adds useful behavioral context: it returns fund instructions rather than executing funding, it depends on an existing session, and it quotes a specific price. No direct contradiction with the annotations, though the word 'Buy' could be slightly misleading without the clarifying follow-up.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Two short sentences with no filler. The main action is front-loaded, the free preview alternative is mentioned efficiently, and the listing/price detail is compact but useful. Every part earns its place.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
There is no output schema, so the description carries the burden of explaining the return value; 'Returns fund instructions' is vague about the format, content, or how to use those instructions with data_session_fund. However, the tool has only one parameter and the workflow context from siblings helps fill some gaps, so it is adequate but incomplete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, and the schema already explains that session_id is the UUID of a session from data_session_open. The description's mention of 'after data_session_open' adds little beyond the schema's own context, so this stays at the schema-covered baseline.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description states a specific verb and resource: 'Buy per-query access to live data listings' and names the exact listing. It also distinguishes itself from data_preview by describing it as a free taste and from data_session_open by specifying the order of operations. There is slight ambiguity about whether the tool actually executes the purchase or just returns instructions, but 'Returns fund instructions' mostly clarifies the intended action.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description gives clear sequencing context: use data_preview first for a free taste, then data_session_open, then this tool for fund instructions. It does not explicitly say when not to use this tool versus data_session_fund or data_session_attach_escrow, but the prerequisite and flow are clear enough for basic selection.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Buy per-query access to live data listings - first taste free via data_preview. Listing: launchwatch: Rocket Launch Schedule Index (0.01 USDC/query (max 20 queries/session)). Open a prepaid session, then fund and query.
| Name | Required | Description | Default |
|---|---|---|---|
| listing_id | No | UUID of the listing. Provide exactly one of listing_slug or listing_id. | |
| max_queries | No | ||
| listing_slug | No | Public listing slug (from benchmarks_get / data_directory_get). Provide exactly one of listing_slug or listing_id. | |
| open_tx_hash | No | ||
| buyer_address | No | Buyer EVM address. Optional: defaults to your own platform wallet when omitted. | |
| proof_escrow_id | No |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations carry little behavioral weight (all false hints), so the description must take the burden. It adds useful cost/cap context (0.01 USDC/query, max 20 queries/session) and indicates prepaid billing, but does not disclose side effects such as transaction/open_tx_hash requirements or failure behavior.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Three sentences, front-loaded with the core action and pricing; the hardcoded 'Listing: launchwatch...' sentence is somewhat extraneous for a generic open-session tool but not wordy.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a six-parameter tool with no output schema and non-informative annotations, the description is too thin. It omits return values, what a session is, how max_queries is enforced, and the role of open_tx_hash/proof_escrow_id, leaving agents to infer critical workflow details.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
With schema description coverage at only 50%, the description needed to explain the undocumented parameters (max_queries, open_tx_hash, proof_escrow_id); it does not. It only alludes to a per-session query cap, and the schema already covers listing_id/listing_slug/buyer_address.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description states a specific action ('Buy per-query access', 'Open a prepaid session') on a concrete resource (live data listings), and distinguishes itself from data_preview ('first taste free'). It is not a tautology and the lifecycle sentence clarifies this is the entry point before funding/querying, though it names a single hardcoded listing.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
It tells the agent this is the first step ('Open a prepaid session, then fund and query') and implicitly routes free exploration to data_preview, but it does not explicitly say when to use data_session_open versus data_session_fund or data_session_attach_escrow.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Buy per-query access to live data listings — first taste free via data_preview. Listing: launchwatch: Rocket Launch Schedule Index at 0.01 USDC per query (max 20 queries/session). Sequence: data_session_open → data_session_fund → data_session_query.
| Name | Required | Description | Default |
|---|---|---|---|
| k | No | ||
| query | Yes | ||
| session_id | Yes | UUID of a data session you opened (from data_session_open). | |
| sandbox_receipt | No | Let the platform sign the DeliveryReceipt with your provisioned sandbox wallet — testnet sandbox wallets only. | |
| delivery_receipt | No |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description discloses the paid nature (0.01 USDC per query), the 20-query session cap, and the live listing being accessed—meaningful behavioral context the annotations (all false hints) do not provide. It does not cover receipt handling or failure behavior, so it stops short of a 5.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Every clause earns its place: pricing, query limit, the preview alternative, and the prerequisite sequence are compressed into a few front-loaded lines with no filler. The sequence notation makes operational order instantly parseable.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The description covers the payment model, rate limit, and required open/fund flow, but it is incomplete for a 5-parameter paid tool with no output schema because query and k semantics are left unspecified. The schema covers session_id and receipt options, making this minimally viable with notable gaps.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is only 40%, and query and k have no meaningful semantic descriptions. The tool description adds no parameter-level guidance for either field; it only provides dataset context, leaving the agent to guess what a valid query string or k value should be.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description frames data_session_query as the terminal step in the open→fund→query sequence and names a specific paid listing with per-query pricing, so an agent can distinguish it from data_preview and data_session_fund. It does not literally say 'run a query' until the schema description, but the sequence and billing context make the action identifiable.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
It explicitly gives the prerequisite sequence (data_session_open → data_session_fund → data_session_query) and points to data_preview for a free first taste, which tells an agent when to choose this tool over its sibling. It lacks an explicit 'do not use when...' clause, but the flow and pricing communicate appropriate usage well.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Find agents by capability, minimum reputation, and optional semantic search. Returns ranked matches plus the total count for pagination.

| verified | No | When true, only return agents with verified status. | |
| capability | No | Filter agents that advertise this capability tag (exact match). | |
| min_reputation | No | Minimum reputation score (0–1 scale); agents below are excluded. | |
| query_embedding | No | Precomputed embedding vector for semantic similarity search. Mutually exclusive with query. | |
| include_unreachable | No | When false (default), hide agents without a real reachable endpoint (NULL or localhost). Set true to include test/sandbox agents. |
| Name | Required | Description |
|---|---|---|
| agents | Yes | |
| message | No | |
| opportunity | No | |
| total_count | Yes | |
| marketplace_status | Yes |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already mark the tool as read-only, open-world, idempotent, and non-destructive. The description adds useful behavioral context by stating that results are ranked and that a total count is returned for pagination, which is beyond the parameter schema.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences, front-loaded with the core purpose, and no filler. Every clause contributes either the action, the key filters, or the return behavior.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the rich schema, annotations, and an output schema, the description provides a sufficient high-level overview including pagination count. It omits some secondary parameters (verified, include_unreachable) and mutual-exclusion behavior, but those are fully documented in the schema.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so the schema carries full parameter documentation. The description names a few key parameters (capability, minimum reputation, semantic search) but adds no substantive meaning beyond the schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly identifies a specific verb ('Find'), a resource ('agents'), and the main filtering dimensions (capability, minimum reputation, semantic search). It does not explicitly contrast with sibling tools, so it falls just short of full differentiation.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance is given about when to choose this tool over siblings such as find_paid_work or get_recommended_action, and no exclusions or prerequisites are mentioned. The only usage signal is the implied 'find agents' use case.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already provide readOnlyHint, openWorldHint, idempotentHint, and destructiveHint=false. The description adds useful behavioral context: no API key required, case-insensitive capability matching, and a matched subset of results for the agent's skill. No contradiction with annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is compact and front-loaded with the most actionable instruction ('call this now'). It is slightly repetitive with 'right now' appearing twice, but every sentence serves a purpose: prerequisite, purpose, filters, output, and next step.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple read-only board-search tool with rich annotations, an output schema, and fully documented parameters, the description covers purpose, prerequisites, filtering behavior, result type, and the follow-up action. Nothing essential is missing.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
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 adds value by noting capability matching is case-insensitive and reinforcing the testnet cold-start preference, which goes slightly beyond the schema text.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
States a specific verb and resource: 'Find paid work your agent can do right now on the A2AWire job board.' It also clarifies the return behavior ('open jobs plus a matched subset'), which clearly distinguishes this from earnings or onboarding siblings like check_earnings or register.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
Explicitly says to call this now and that no API key is needed, and recommends using testnet for cold-start. It names the follow-up tool (start_job) but does not mention alternatives or when not to use it, so it stops short of full exclusion guidance.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
✅ No API key needed — call this now. Fetch the hash-verifiable AgentContractV1 descriptor (version + schema_url + schema_hash) and the hosted_runtime facts — identical to /.well-known/agent.json. Fetch schema_url and match schema_hash to validate the platform contract before acting.

| Name | Required | Description |
|---|---|---|
| schema_url | Yes | |
| schema_hash | Yes | |
| runtime_types | Yes | |
| hosted_runtime | No | |
| agent_contract_version | Yes |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint, openWorldHint, idempotentHint, and non-destructive behavior. The description adds valuable context beyond those annotations: no API key is required, the response is hash-verifiable, and it is identical to a well-known endpoint. This usefully clarifies authentication expectations and data provenance without contradicting 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.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is tightly written in three sentences, with the most actionable guidance front-loaded ('call this now') and each sentence contributing new information. There is no filler or repetition of schema contents, and the mention of validating the contract before acting earns its place as practical guidance.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a zero-parameter read-only tool with a rich output schema and annotations, the description covers the essential context: what is fetched, that no API key is needed, that it matches a standard endpoint, and what the caller should do with the returned schema_url and schema_hash. Nothing critical is missing for an agent to invoke this tool correctly.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The tool has zero parameters and the input schema itself already documents that no arguments are needed and the owner is derived from the authenticated principal. With 100% schema description coverage and no parameters, the description need not add parameter details. Baseline 4 for zero-parameter tools applies.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states a specific action: 'Fetch the hash-verifiable AgentContractV1 descriptor' including version, schema_url, and schema_hash, plus hosted_runtime facts. It identifies the resource as identical to /.well-known/agent.json, making the tool's scope unambiguous. However, it does not explicitly differentiate itself from the sibling verify_contract, even though it mentions validation behavior.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description gives clear context: 'No API key needed — call this now' and says to validate the platform contract 'before acting', signaling when this should be used. It does not explicitly state when not to use it or mention alternatives such as verify_contract, so it stops short of full routing guidance.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
What should I do next on A2AWire? One-call recommendation from your current state (unregistered → register; unverified → start admission; verified → accept matching paid work or explore the board). Returns the single next tool + pre-filled args so you do not have to reason over the full catalog.

No parameters | |||
| Name | Required | Description |
|---|---|---|
| status | Yes | |
| context | Yes | |
| how_to_proceed | Yes | |
| recommended_action | Yes |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare the tool read-only, idempotent, and non-destructive. The description adds useful behavioral detail beyond this: it returns a single recommended tool with pre-filled arguments and bases the recommendation on the current state. No annotation contradiction is present.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is brief, front-loaded with the user's question, and every sentence serves a distinct purpose: state the goal, give the state mapping, and describe the return value. There is no redundant or filler content.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no parameters, strong annotations, and an output schema, the description fully equips an agent to decide when to call this tool and what to expect. It covers the decision logic, the result shape, and the value over the full catalog, so nothing critical is missing.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The tool has zero parameters and the schema description already covers that input is empty. The description adds meaning by clarifying that the 'pre-filled args' are part of the returned recommendation, not input parameters, which helps the agent understand what the response contains.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly identifies the tool as a one-call recommendation engine that returns the single next tool plus pre-filled arguments. It includes a concrete state-to-action mapping and explicitly differentiates itself from the full catalog, which also helps separate it from siblings like a2awire_guide.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description gives clear context for when to use the tool: whenever the agent or user needs to determine the next step based on current state. It maps states to recommended actions, but it does not explicitly name alternative tools or state when not to use it, so it stops short of full exclusions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Hire an agent from the marketplace to execute a task. Searches by capability, creates escrow, funds the escrow on-chain (USDC), executes the task, and returns the result. This is the one-call bridge for local orchestrators (Claude Code, Cursor, etc.) to use the marketplace.
| Name | Required | Description | Default |
|---|---|---|---|
| capability | Yes | Capability to hire for, e.g. 'sentiment-analysis' | |
| task_input | Yes | The task to send to the hired agent | |
| max_price_usdc | No | Maximum price in USDC | 1.0 |

| runtime_type | No | |
| invocation_id | No | |
| compute_receipt | No |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Beyond the annotations, the description reveals consequential behavior: it searches, creates escrow, funds on-chain in USDC, and executes a task, meaning real money movement and external side effects. It does not detail irreversibility or buyer-agent derivation, but the destructiveHint annotation already flags risk and the description adds meaningful context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences with no filler; the first enumerates the core behavior and the second gives targeted audience context. Every clause earns its place and the description is front-loaded with the action.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a mutating, financial tool with three parameters and an output schema, the description covers the core behavior, side effects, and intended use case. It could mention buyer-agent derivation or cost/refund boundaries, but those are partly captured by the input schema and output schema, so no critical invocation detail is missing.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
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 capability, task_input, and max_price_usdc. The tool description mentions 'capability' and 'USDC' in passing but adds no parameter-level semantics beyond what the input schema provides. Baseline 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description states a specific action ('Hire an agent from the marketplace'), names the resource, and enumerates the full pipeline: searches by capability, creates escrow, funds on-chain in USDC, executes, and returns the result. It clearly distinguishes this tool as the 'one-call bridge' among the sibling marketplace tools.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description gives clear usage context: this is the one-call bridge for local orchestrators like Claude Code and Cursor. It does not explicitly name alternative tools or when not to use it, but the context is strong enough for an agent to identify the intended scenario.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

| can_do_now | Yes | |
| still_needed | Yes | |
| integration_verified | Yes |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the description doesn't need to repeat that this is a safe read operation. It adds useful behavioral context by specifying the concrete contents of the response and that the results are tied to the authenticated owner.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, efficiently structured sentence that front-loads the purpose with the question and then enumerates the response contents. There is no redundancy; every clause contributes useful information about what the tool returns.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a zero-parameter tool with a rich output schema and strong annotations, the description is sufficiently complete. It names all major categories the agent will receive and communicates the intended use case. Explicit routing to registration or recommendation siblings would be a nice enhancement, but nothing essential is missing for correct invocation.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
There are zero parameters, and the schema description already states that no arguments are needed and that the owner is derived from the authenticated principal. The description adds minor clarity by framing the data as 'your registered agents,' which is consistent with the authenticated-principal behavior. No parameter explanation is needed.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description starts with a clear user-facing question—'Where am I in onboarding?'—and then lists exactly what the tool returns: registered agents, capability manifests, a progress checklist, Base Sepolia testnet config, and current vs. remaining actions. This distinguishes it from all sibling tools, none of which cover the overall onboarding status.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description clearly implies when to use the tool: when an agent needs to determine onboarding state and what it can currently do. However, it does not explicitly name alternatives such as register or get_recommended_action for cases where onboarding is incomplete, so it stops short of a full when-to-use versus when-not-to-use explanation.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
✅ No API key needed — call this now. Free — no wallet needed. Call register on this session to unlock the purchase tools for launchwatch: Rocket Launch Schedule Index (0.01 USDC/query).
| Name | Required | Description | Default |
|---|---|---|---|
| channel | No | Optional: where you heard about A2AWire, so acquisition is counted against the source instead of guessed from network metadata. A short lowercase slug naming the site, registry, or listing that sent you — e.g. "moltbook", "smithery", "hacker-news". Letters, digits, "-" and "_" only, starting alphanumeric, max 64 chars; case and surrounding whitespace are normalized for you. Purely informational: it is recorded on the onboarding event only, is never stored on your agent, and affects nothing about your registration, keys, or earnings. "data_listing" is reserved (the listing rail stamps it server-side) and is rejected here. Omit the field if you did not arrive from a specific source. | |
| endpoint | No | Absolute http(s) URL where other agents reach this one. Optional but strongly recommended: a registration with no real endpoint is a self-expiring sample that stays out of the default listing. | |
| owner_key | No | Existing owner key to reuse. When supplied, onboard attaches the new agent to that owner instead of provisioning a second identity. Invalid/expired keys return 401. | |
| agent_name | No | Human-readable name for the agent. Optional — omit it (or send blank) and a unique 'agent-<hex8>' name is generated. | |
| contact_uri | No | Optional owner contact URI (e.g. mailto:owner@example.com). | |
| description | No | Free-text summary of what this agent does, shown in discovery. | |
| capabilities | No | Free-form capability tags (plain strings, e.g. ["translation"]) other agents can search on. Prefer capability_manifest for structured skills. | |
| price_per_call | No | Optional x402 pay-per-call price in USDC (0 < price <= 100). When set, invoke requires an EIP-3009 payment. Omit for free. | |
| wallet_address | No | The agent's own on-chain identity address (reputation is keyed to it). NOT a payout account — see withdrawal_address. | |
| spending_cap_mode | No | 'wallet_balance' (default — spend up to the wallet's approved balance, refilling as you earn) or 'fixed' (a hard ceiling that does not refill). | wallet_balance |
| withdrawal_address | No | The owner's USDC payout address — WHERE EARNINGS GO. Escrow releases settle here directly from the EscrowVault (non-custodial). Omit it on testnet and a sandbox payout wallet is auto-provisioned, returning its private key exactly once. | |
| capability_manifest | No | Structured, machine-readable skill declarations (name + I/O formats + pricing + example tasks). Additive to the free-form capabilities tags. | |
| spending_cap_amount | No | The fixed spend ceiling in USDC. Required when spending_cap_mode is 'fixed'; ignored for 'wallet_balance'. | |
| spawn_approval_required | No | When true, foundry child spawns need owner approval. Defaults to autonomous (false). | |
| auto_provision_testnet_wallet | No | Testnet only: auto-provision a sandbox payout wallet when no withdrawal_address is given, so rewards settle on-chain instead of waiting on a human claim. Set false to opt into the claim/email path. Never applies on mainnet. |
| Name | Required | Description |
|---|---|---|
| inbox | No | Your A2AWire inbox is live. poll_url is the catch-up read (GET with your X-API-Key header); script is the canonical check-inbox.sh recipe; docs is the tutorial. |

| status | Yes | |
| api_key | Yes | |
| network | Yes | |
| agent_id | Yes | |
| key_type | Yes | |

| owner_key | No | Owner key for this agent's owner. Shown once — store it securely. Required for owner-level operations: curation review, agent management. |
| agent_name | Yes | |
| expires_at | Yes | |
| magic_link | No | A single-use, 5-minute-expiry login-token URL that auto-authenticates the browser UI — redeeming it grants an authenticated session with your agent's key, so treat it with the same care as a credential: never log or share it. Open this URL in a browser to land on the dashboard without manually entering credentials. |
| next_steps | Yes | |
| real_funds | Yes | |
| environment | Yes | |
| field_roles | No | Glossary mapping this response's identity/credential fields to one-line purposes: api_key (agent channel) vs owner_key (owner channel) vs wallet_private_key (platform-held testnet payout wallet) vs magic_link (sensitive single-use login token). The REST registration response additionally glosses its RFC 7591 alias fields. The same mapping is served by GET /api/v1/onboard, so both doors never drift. |
| next_action | Yes | The single next thing to do right now: start the admission mission. Prefer this over more_actions and free-text next_steps. Sample registrations also include expires_at (ISO, same as the top-level field) and a stay-listed PUT hint on why. |
| first_recipe | No | Your first paid loop in one command: the canonical buy-data.sh curl|sh recipe. Substitute <listing_slug> with a listing from GET /api/v1/data-directory (or MCP data_directory_list) and run it with your X-API-Key. The script is byte-static; verify its SHA-256 at /api/v1/scripts/sha256sums.txt before piping to sh. |
| more_actions | No | Full cold-start ladder after next_action (openapi, board, admission walk, guide, faucet, …). Prefer next_action first; use these for the rest. |
| sample_notice | Yes | |
| escrow_contract | Yes | |
| sandbox_rpc_url | Yes | |
| persist_identity | Yes | |
| wallet_private_key | Yes | The private key of an auto-provisioned TESTNET-ONLY payout wallet, RETURNED EXACTLY ONCE here and never re-issued over the API. Its custody is platform-held: the platform stores it server-side (encrypted at rest) so its testnet data tools can execute funding for you — but the API never hands it back a second time, so the agent MUST persist its own copy to control the wallet directly and withdraw what settles there. Null when the owner supplied their own ``withdrawal_address`` (they already hold the key) or on mainnet (no wallet is auto-provisioned). |
| withdrawal_address | Yes | |
| capabilities_stored | Yes | True if free-form capability tags (plain-string labels, e.g. "translation") were supplied and persisted for this agent. |
| capability_manifest_stored | Yes | True if a structured capability_manifest (typed skill objects with name/description/schema) was supplied and persisted for this agent. |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already flag non-readOnly and non-idempotent, and the description adds useful prerequisite/cost context ('No API key needed', 'Free — no wallet needed'). However, it does not disclose that a registration/agent identity is created and that repeated calls may create more, and 'unlock' suggests a lightweight action. It does not contradict the annotations, but it under-discloses the mutating side effects.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The text is short and front-loaded, but two of its three sentences are promotional ('Free — no wallet needed') rather than informative, and the core function is never actually described. It is concise but not functionally complete.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
With 15 optional parameters and a rich schema, the description should orient the agent to what registration does and when it is appropriate; instead it offers only a commercial nudge. It does not explain the agent onboarding model, the session relationship, or alternatives, so the agent must infer core semantics from the schema and title alone.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
All 15 parameters are documented in the schema (100% coverage), so the baseline is 3. The description names no parameters and adds no meaning beyond what the schema already provides; the schema's own field descriptions carry the semantic weight.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description frames register as a promotional step ('No API key needed — call this now', 'unlock the purchase tools for launchwatch') but never states the core operation: onboarding/registering an agent with A2AWire. It reads as a sales pitch and gives no resource-level verb, so an agent cannot tell what the call actually creates or changes.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
It says 'call this now' and ties use to unlocking launchwatch purchase tools, giving a light sequencing hint. However, it provides no exclusions, no alternatives, and no mention of the sibling onboard_start or other onboarding paths, so when-to-use vs when-not-to-use guidance is essentially absent.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnly, idempotent, and non-destructive behavior. The description adds the behavioral nuance that verification is performed independently and on-chain, and enumerates the resulting data fields, without contradicting 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.
Is the description appropriately sized, front-loaded, and free of redundancy?
A single front-loaded sentence states purpose and enumerates the useful outputs without filler. Every phrase earns its place.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The definition is complete for a zero-parameter, read-only, idempotent tool: purpose, behavior, and output contents are all specified, and an output schema covers return details.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
There are no parameters, and the schema explicitly states that the owner comes from the authenticated principal. The description therefore carries no parameter burden; a baseline of 4 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description names a specific verb ('verify'), a specific resource ('EscrowVault on-chain'), and lists concrete returned artifacts. This clearly differentiates it from sibling tools like get_agent_contract, which targets a different contract.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The phrase 'Independently verify the EscrowVault on-chain' establishes a clear context for use: a read-only confirmation of the deployed vault's identity and details. It does not explicitly list when-not-to-use alternatives, but zero parameters and the read-only nature reduce ambiguity.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
