Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false, and openWorldHint=false, so the safety profile is fully covered. The description adds that the tool surfaces intermediate progress as well as final outputs, which is modest extra value, but it says nothing about polling behavior, whether tasks persist, or how in-progress results differ from completed ones.
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 primary verb ("Check") leading and the three sub-capabilities following in a compact list. No filler, no redundancy.
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 single-parameter read tool with full annotations and an output schema, the description covers enough that the agent knows when and how to call it without needing to explain return values. Minor gaps around polling/refresh expectations keep it from a 5.
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 a single parameter and 100% schema description coverage, the schema already documents task_id and its expected format ("task_..."). The description adds no semantics beyond what the schema provides, so the 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 verb+resource combination ("Check task execution status") and enumerates three concrete capabilities: status checking, progress inspection, and deliverable retrieval. It clearly does not overlap with the sibling tools (search_marketplace_agents, list_available_agents, publish_agent_task), though no sibling is named 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 gives clear usage context by listing the scenarios it serves (status, intermediate progress, completed outputs), so an agent knows what to reach for it for. It stops short of stating when NOT to use it or naming an alternative tool, but the sibling set is functionally distinct enough that no routing conflict arises.
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 readOnlyHint, idempotentHint, openWorldHint and destructiveHint=false, so the safety profile is fully covered. The description adds the 'active' scoping filter, which is useful behavioral context, but the field list (skills, price, reputation) is redundant with the output schema and no pagination or result-size behavior is disclosed.
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 no filler, stating scope, resource and contents in one pass.
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 enumeration tool with an output schema, the description covers scope ('active', 'on the marketplace') and contents adequately. The only real gap is the absence of any signal about result size, pagination, or how it relates to the search sibling.
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 takes zero parameters and the schema is trivially complete, so there are no parameter semantics to explain. The baseline of 4 applies since nothing is missing or ambiguous.
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 ('List all active provider agents registered on the marketplace') and names the returned fields, so an agent immediately knows what it retrieves. It does not explicitly differentiate itself from the sibling search_marketplace_agents, leaving the list-vs-search distinction to inference from the word 'all'.
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: 'List all active' suggests this is the unfiltered enumeration path, contrasting implicitly with search_marketplace_agents, but no when-to-use or when-not-to-use condition is stated. No prerequisites or alternatives are named.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

| deadline_seconds | No | Execution deadline in seconds |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations cover the safety profile (readOnlyHint=false, destructiveHint=false, idempotentHint=false), so the bar is lower, but the description adds substantive context the annotations do not: this operation locks escrow funds (a financial commitment) and branches between directed dispatch and open bidding. It does not explain escrow reversibility, refund behavior, or what happens on failure/timeout, so it stops at 4.
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 efficient sentence that front-loads the core action and appends the two dispatch modes. Nothing is padded, though the embedded tuple notation consumes space without adding usable meaning.
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?
An output schema exists, so return values need not be described, and with 100% schema coverage the parameter contract is fully specified. What the description supplies—the escrow lock and the directed-vs-bidding branch—is the key non-structured context. It omits preconditions (buyer agent validity, sufficient funds) and post-publish follow-up via check_task_status, leaving a minor gap.
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 documents all six parameters including the OPEN_FOR_BIDDING sentinel for target_agent_id. The description only gestures at the dispatch/bidding parameter indirectly and adds no format, default, or unit detail beyond the schema. Baseline 3 is appropriate when the schema does the heavy lifting.
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 ("Commission") and resource ("task") and states two concrete outcomes: escrow lock plus dispatch or competitive bidding. It clearly reads as a create/publish operation, distinguishing it from the sibling list/search/status tools. The "T = <O, D, C, Q>" notation adds opaque jargon rather than clarifying the operation, keeping it just short of a 5.
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 parenthetical "(or opens competitive bidding)" implies the two modes an agent can choose between, and the schema's target_agent_id description elaborates on OPEN_FOR_BIDDING. However, there is no explicit when-to-use guidance, no prerequisite (e.g. find an agent via search_marketplace_agents first), and no exclusion criteria. Usage is implied rather than stated.
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 readOnlyHint, idempotentHint, openWorldHint and destructiveHint=false, so the safety profile is covered. The description adds the filter dimensions but says nothing about ranking, semantic-matching behavior, or result-set characteristics beyond what annotations and schema provide, which is acceptable but thin.
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 no filler; the verb and resource lead and the filter list follows. Nothing needs to be cut.
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?
An output schema exists and annotations cover safety, so return values and side effects need not be explained. The remaining gap is the unaddressed relationship to sibling search/list tools and the dangling 'tags' reference, leaving the definition just adequate rather than complete.
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 all four parameters are already documented in the schema, making 3 the baseline. The description restates budget and reputation conceptually but adds no syntax or format detail, and it references a 'tags' filter that does not exist as a parameter, which slightly muddies rather than clarifies.
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?
State a specific verb (search) and resource (AI provider agents on the marketplace) plus the filter dimensions, so the agent knows exactly what the tool retrieves. It does not, however, name or contrast itself with the sibling list_available_agents, which is the obvious confusable, so it falls short of a 5.
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, no prerequisites, and no mention of alternatives such as list_available_agents or how this differs from browsing the marketplace. The agent must infer from the name alone that this is the query-based retrieval path.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Recent tool additions, removals, and schema changes observed during successful MCP inspections.
v0.1.0check_task_statuslist_available_agentspublish_agent_tasksearch_marketplace_agentsScored across 4 tools
search_marketplace_agents and list_available_agents both retrieve provider agents and could be confused, but the former is filtered and the latter is a full list. publish_agent_task and check_task_status are clearly distinct actions.
All tool names use consistent snake_case with a verb-first pattern (search_, list_, publish_, check_), making the actions predictable.
Four tools is within the typical well-scoped range for a focused marketplace/task server, and each tool corresponds to a distinct primary operation.
The set supports creating a task and checking its status, but lacks update, cancel, list tasks, escrow release, and bid management operations. These are notable gaps for a marketplace with escrow and competitive bidding.
