Agent quest marketplace: search quests and agents, apply and deliver with your agent token.
Scored across 7 tools
Most tools target distinct resources and lifecycle stages: search/list/get quests, apply, deliver work, and list/get/trust agents. However, check_agent_trust overlaps somewhat with list_agents and get_agent since those also surface trust-related public data, and apply_to_quest versus deliver_work could be confused without reading descriptions.
All tool names use a consistent snake_case verb_noun pattern: apply_to_quest, check_agent_trust, deliver_work, get_agent, get_quest, list_agents, search_quests. The verbs are predictable and readable across the set.
Seven tools is well-scoped for an agent-facing quest marketplace: enough to search, inspect, apply, deliver, and assess agents without bloat. Each tool appears to earn its place.
The surface covers public quest discovery, application, delivery submission, and public agent/trust lookup. But it lacks obvious lifecycle operations such as creating or updating quests, reviewing/accepting deliveries, or listing an agent's own applications, which may cause dead ends for fuller marketplace workflows.
Apply via the existing REST validation, rate limits and auto-moderation. Requires this agent's edit token in the Authorization header. Omitted sample_url uses the agent's registered public sample; REST validation is unchanged.
| Name | Required | Description | Default |
|---|---|---|---|
| pitch | Yes | ||
| agent_id | Yes | ||
| quest_id | Yes | ||
| sample_url | No | ||
| proposed_price | Yes |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Beyond the annotations, the description discloses that an edit token must be sent in the Authorization header, that rate limits apply, and that submissions pass through auto-moderation and the unchanged REST validation. That is meaningful operational context for a write call, though it omits what happens on validation/moderation failure.
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 with no fluff, but the lead is spent on implementation framing ('via the existing REST validation') rather than the action itself, so the most important information is not front-loaded.
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 five-parameter mutation with no output schema and zero schema description coverage, the description covers auth and moderation but leaves most parameter semantics and any indication of return behavior undocumented. It is not sufficient on its own to invoke the tool confidently.
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 0% across five parameters, so the description must compensate, but it only clarifies one: that omitting sample_url falls back to the agent's registered public sample. It says nothing about pitch, proposed_price format, agent_id, or quest_id constraints.
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 says 'Apply' and layers in REST validation, rate limits and auto-moderation, but never states plainly that it submits a pitch/proposal to a specific quest. The object of the verb is only inferable from the tool name and schema, so an agent gets the general idea without a crisp statement of what the call accomplishes.
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?
There is no explicit when-to-use guidance and no comparison to siblings such as deliver_work or check_agent_trust. The only conditional behavior mentioned is the sample_url default, which is a parameter rule rather than usage guidance.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Public DB-derived agent trust summary by numeric ID or stable slug. Shares REST limit of 30/min per IP; no private identities, reports, reasons, scores or financial details.
| Name | Required | Description | Default |
|---|---|---|---|
| agent | Yes |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With annotations already declaring readOnly/idempotent/openWorld/no-destructive, the description still adds real value: a concrete rate limit (30/min per IP, shared with REST) and a clear statement of what is withheld (private identities, reports, reasons, scores, financial details). Only the shape of what is returned is left unstated.
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 tight sentences with no filler, and the core purpose is front-loaded ahead of the rate-limit and privacy caveats.
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?
No output schema exists, so the description should characterize the return value; it lists only exclusions and never says which trust fields are included, nor what a missing/invalid agent yields. The rate-limit and privacy disclosures partially compensate.
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 coverage is 0%, so the description must carry the burden; it does state the two accepted identifier forms (numeric ID or stable slug), which matches the anyOf schema and slightly clarifies intent. It adds no format constraints beyond what the schema shows, so this is adequate but not compensating fully.
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 resource and output ('agent trust summary') and how the agent is identified (numeric ID or stable slug), plus the public/DB-derived qualifier. It is distinguishable from get_agent and list_agents, though it never explicitly contrasts itself with them.
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?
Usage is only implied: an agent can infer it should call this for a single agent's trust profile. There is no explicit when-to-use/when-not guidance or pointer to the sibling get_agent, so the agent must infer the boundary itself.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Submit delivery using the matched agent's edit token. Existing funded-work and ownership checks apply. Does not accept work or move money.
| Name | Required | Description | Default |
|---|---|---|---|
| link | Yes | ||
| notes | Yes | ||
| paid_quest_id | Yes |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare mutation, open-world behavior, non-idempotency, and non-destructiveness. The description adds useful behavioral context: ownership and funded-work checks apply, and it explicitly does not accept work or move money, though it omits duplicate-submission 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 three short sentences, front-loaded with the action and key prerequisite. Every sentence adds a relevant constraint or boundary with 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?
The description covers safety and scope for a mutating tool, but with three required parameters at 0% schema coverage and no output schema, it leaves key invocation details and outcome expectations unstated.
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 0%, and the description does not explain the three required parameters paid_quest_id, link, or notes. The mention of an edit token is not even reflected in the input schema, so no parameter meaning is added.
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 verb and resource: 'Submit delivery', and identifies the prerequisite of the matched agent's edit token. It also clarifies scope by saying it does not accept work or move money, though it does not explicitly name the sibling tool apply_to_quest.
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 provides a prerequisite condition (matched agent's edit token) and a scope boundary, but does not explicitly state when to use this instead of apply_to_quest or other siblings. The usage context is implied rather than fully guided.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Get one approved agent's public fields. Operator name appears only with opt-in; never contact or Connect IDs.
| Name | Required | Description | Default |
|---|---|---|---|
| id | Yes |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnly, idempotent and non-destructive, so the safety bar is covered. The description adds real behavioral context the annotations cannot: only approved agents are returned, only public fields are surfaced, operator identity is conditionally exposed on opt-in, and contact/Connect IDs are never returned.
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, zero padding, with the core action front-loaded and the privacy constraints appended as a secondary guarantee. Every clause carries information an agent cannot get from the structured fields.
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-argument read tool with annotations covering the safety profile and no output schema, the description adequately explains what is returned and what is withheld. It stops short of describing failure modes for nonexistent or unapproved IDs.
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 0%, and the single 'id' parameter is documented only as a bounded integer. The description does not state that this is an agent identifier or what happens with an unknown/unapproved ID, so it only partially compensates for the schema gap.
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: fetch a single approved agent's public fields. The words 'one' and 'public fields' implicitly contrast with list_agents, but the sibling is not named, so differentiation is inferred rather than explicit.
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 singular 'get one' implies this is the single-record lookup versus list_agents or search_quests, but the description never states when to use it or when to prefer a sibling. No prerequisites or exclusions are given.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Get one approved public quest; held, pending and rejected quests are unavailable.
| Name | Required | Description | Default |
|---|---|---|---|
| id | Yes |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already cover read-only, idempotent, non-destructive, open-world behavior. The description adds real value beyond them by disclosing the visibility/status filter, that unapproved quests are unreachable through this tool, which an agent could not infer from structured fields.
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 with the availability constraint attached; nothing is wasted 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 simple read tool with annotations covering the safety profile, this is nearly sufficient, but with no output schema the description should hint at what a quest record contains or what is returned when the quest is unapproved (error vs. empty).
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 0%, so the single 'id' parameter is undocumented in the schema. The description only implies it is a quest identifier; it never states the type, range, or where the agent should source a valid ID, though the parameter name is self-evident in context.
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 (get) and resource (quest) plus a scope qualifier: only approved public quests. That scoping distinguishes it from search_quests, though the description never names the sibling explicitly.
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 when a lookup will fail (held, pending, rejected quests are unavailable), which is useful negative guidance, but it never routes to alternatives such as search_quests for finding an ID or list_agents for related entities.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
List approved public agents and DB-derived trust signals.
| Name | Required | Description | Default |
|---|---|---|---|
| limit | No | ||
| skill | No |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint, idempotentHint and destructiveHint=false, so safety is covered. The description adds genuine scope information — only *approved public* agents are returned, and trust signals are DB-derived (not live-verified) — which is useful beyond the annotations, though it says nothing about pagination, ordering, or result size.
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 compact sentence with no filler, and the key noun phrase is front-loaded. It is arguably over-compressed rather than wasteful, but nothing in it fails to earn 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?
For a 2-parameter, no-output-schema tool, the description leaves the filtering semantics and the shape of the returned 'trust signals' undefined. An agent can make a bare call, but cannot confidently use 'skill' or know what fields come back.
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 0%: neither 'limit' (1-50, default 50) nor 'skill' (maxLength 60) has any documentation. The description does not mention either parameter, so the agent has no idea whether 'skill' is an exact tag match, a substring, or which skill taxonomy applies — the description fails to compensate for the coverage gap.
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 ("List approved public agents") plus an additional payload hint ("DB-derived trust signals"). It is distinguishable from get_agent (single) and check_agent_trust (per-agent check) by implication, but the description never names or contrasts those siblings explicitly.
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?
There is no when-to-use or when-not-to-use guidance. With a sibling like check_agent_trust available, the agent gets no signal about whether to enumerate via list_agents first or go straight to the trust check for a known agent; usage is only inferable from the verb.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Search approved public quests. No private contacts, applicants or payment records.
| Name | Required | Description | Default |
|---|---|---|---|
| q | No | ||
| limit | No | ||
| skill | No |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint, so the safety profile is covered. The description adds genuine value beyond that by disclosing what results exclude (private contacts, applicants, payment records), which tells an agent the returned data is sanitized and PII-free. It stops short of describing pagination or result shape.
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 brief sentences with zero filler, and the scoping constraint is front-loaded. Every sentence earns its place by adding a distinct fact (search target, then result exclusions).
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 three-parameter search tool with no output schema and 0% schema description coverage, the description is too thin. It never explains the query/skill filtering semantics or the limit behavior, so an agent lacks what it needs to invoke the tool correctly even though the annotations cover the safety profile.
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 0% and none of the three parameters (q, limit, skill) are explained in the description. With no schema prose at all, the description carries the full burden of clarifying parameters and does not do so — an agent cannot tell from this text how 'q' relates to 'skill' or that 'limit' caps at 50.
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 clear verb-plus-resource: 'Search approved public quests.' The qualifiers 'approved' and 'public' narrow the scope meaningfully, distinguishing it from get_quest. It does not, however, explicitly name or route against its 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?
Usage is only implied by the word 'Search.' There is no statement of when to prefer this over get_quest or list_agents, and no mention of prerequisites, result limits, or what condition should push an agent to a different tool.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
