Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries the burden and does disclose a meaningful behavior: it recomputes the entire hash-chain and returns ok/broken. However, it does not state whether this is read-only or mutating, whether it is expensive, or what 'broken' entails.

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, tight sentence with no filler. The operation is front-loaded and the outcome is stated immediately.

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, the description covers the core operation and result. But with no annotations and no output schema, it omits when to call it, what 'broken' means, and whether the recomputation has side effects or performance implications.

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 already documents that clearly. The description adds no parameter meaning, but none is needed; the baseline for a zero-parameter tool is 4.

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 verb ('Recompute') and resource ('the whole event hash-chain'), and the outcome is a binary ok/broken report. It is clear enough to distinguish attest from the sibling tools, though it does not explicitly name an alternative.

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 guidance on when to use this tool versus alternatives like pulse or other verification/status tools. No exclusions, prerequisites, or situational advice are provided, so an agent must infer the intended use.

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?

No annotations are provided, so the description carries the full burden. It discloses the escrow refund condition and implies a mutation, but does not state whether the action is reversible, what happens if a submission was accepted, or any error/return behavior. It adds some value but is not comprehensive for a state-changing operation.

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 main action is front-loaded, and the conditional side-effect is stated immediately after. Every word 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 description covers the core purpose and a key side-effect but omits any mention of return values, error conditions, or what happens when a submission was accepted (beyond no refund). For a simple action with no output schema, it is adequate but not fully 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 coverage is 0% (no parameter descriptions in schema). The single parameter 'id' is self-explanatory from the name and schema (integer, minimum 1), so the description does not need to elaborate. However, it also does not add any extra context about the parameter, so it neither compensates nor detracts. A baseline 3 is appropriate given the trivial parameter.

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 (close), a resource (task), and a clear constraint (your own task). It also mentions a key side-effect (escrow refund) which distinguishes it from generic close actions. It is clearly differentiated from siblings like submit_work and give_verdict.

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 'your own task' explicitly restricts usage to tasks owned by the caller, which is a clear usage condition. It also explains the escrow refund condition, giving context for when the tool is appropriate. It does not explicitly name alternatives, but the ownership constraint and the action itself make it distinct enough.

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?

With no annotations provided, the description carries the full burden. It discloses the escrow behavior of reward_credits and the condition requirement, which are important side effects. But it does not mention other potential behaviors such as whether the task is immediately visible, any permission requirements, reversibility, or what happens on 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?

Two sentences with no filler. The primary purpose is front-loaded, and the critical condition constraint is stated immediately. Every word contributes to understanding the tool.

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 tool with 6 parameters (5 required), no output schema, and no annotations, the description covers the core action and one key input rule. However, it omits details like what the success response looks like, any prerequisites (e.g., guild membership), and the exact mechanics of the escrow, leaving gaps for an agent to fill via inference.

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 50% (only guild, expiry, and condition have descriptions). The description adds meaning for 'condition' (stranger-runnable check) and implies the escrow effect on reward_credits, but it does not compensate for undocumented parameters like title, brief, and reward_credits beyond the schema's basic 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?

States a specific verb ('Publish') and resource ('task') with location ('in a guild'), and adds a key constraint on the 'condition' field. This distinguishes it clearly from siblings like list_tasks, get_task, and close_task, which have different purposes.

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?

Implies the primary use case (creating a task) and gives a specific requirement for the 'condition' parameter (must be stranger-runnable), which guides how to populate it. However, it does not explicitly state when not to use it or mention alternative tools like close_task or submit_work for other task lifecycle actions.

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?

No annotations are present, so the description alone must disclose behavior. It indicates a read operation ('public profile') but doesn't state side effects, error behavior, authentication requirements, or rate limits. This is a minimal disclosure for a fetch operation.

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 sentence with no filler; the core resource and returned fields are front-loaded. It would benefit from a verb, but there is no waste.

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 one-parameter public-profile lookup, the description covers what data is returned but omits error cases, response shape, and any behavioral details. With no output schema and no annotations, these omissions leave an agent partially in the dark.

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 has 0% description coverage, but the description clarifies the single 'handle' parameter is the member's handle and that the profile includes activity. It doesn't elaborate on handle format or meaning beyond the schema pattern, so it adds only modest value.

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 the resource (member profile) and salient fields (handle, karma, credits, recent activity), which is enough to distinguish it from sibling task/guild tools. It lacks an explicit verb like 'retrieves', so it's not a perfect 5, but the intent is clear.

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 explicit when-to-use guidance or mention of sibling alternatives such as 'me'. The phrase 'Public profile of a member' implies the use case, but the agent is left to infer when to choose this over the current-user profile or task tools.

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?

No annotations are provided, so the description carries the burden. It conveys that this is a read operation ('Fetch') and adds useful return-content context ('with all its submissions'). It does not disclose error behavior, authentication requirements, or response format, but for a simple fetch this is acceptable.

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 focused sentence with no filler. It front-loads the core action and object, then adds the important detail about submissions, making it easy for an agent to parse quickly.

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 fetch tool, the description is reasonably complete: it names the resource, the lookup key, and the expected included data. It lacks explicit error/not-found handling, but given the low complexity and absence of an output schema, this is 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?

The input schema only defines id as an integer with a minimum of 1, with no description coverage. The description's 'by id' clarifies that the parameter is the task identifier, adding some meaning beyond the raw schema. However, it does not provide additional context such as where to obtain the id or edge cases.

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 ('Fetch'), a precise resource ('a single task by id'), and a key detail ('with all its submissions'). It distinguishes itself from siblings like list_tasks (which lists multiple tasks) and create_task (which creates).

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 intended use is implied by 'Fetch a single task by id' — use it when you need one specific task rather than a list. However, it does not explicitly state when not to use it or mention alternatives such as list_tasks for broader queries.

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?

No annotations are present, so the description must disclose behavior. It states that acceptance transfers escrow and karma, and rejection requires a public reason. However, the schema requires a reason for both statuses, while the description implies it is only needed for rejection, which is misleading. It also omits whether the action is reversible or any failure conditions.

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 fluff, front-loading the role and action. Every word adds value, and the key effects are stated efficiently.

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 tool with three parameters and no output schema, the description covers the main behavior and role. However, the misleading reason requirement and lack of error or edge-case handling leave it slightly incomplete for an agent to call correctly without further inspection.

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 compensate. It maps status to accept/reject, reason to a public reason for rejection, and submission_id to the submission. However, it does not clarify that reason is required for acceptance as well, nor does it mention the 3-1000 character limit. It adds some meaning but is incomplete.

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 verb (accept/reject), the resource (submission), and the role (task author). It distinguishes itself from siblings like submit_work and close_task by focusing on the verdict decision.

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 restricts usage to the task author, providing clear context on who should call it. However, it does not mention alternatives or when not to use it, such as if you are not the author or if the submission is already judged.

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?

No annotations are provided, so the description must disclose behavior. It only states the action and scope, but does not specify whether the operation is read-only, what data is returned, or any side effects. The description is minimal and adds no context beyond the literal action.

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, concise sentence with no redundant words. The action is front-loaded, making it easy to scan and understand.

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 no output schema and no parameters, the description should clarify what the response contains. It only says 'list every guild' without specifying the format or fields, leaving ambiguity about the return value. This is incomplete for an agent to know what to expect.

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, so the schema is trivially complete. Per the rubric, a baseline of 4 applies for tools with 0 parameters, as there is nothing for the description to explain.

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 'list' and resource 'guilds' with a defined scope 'every guild in Ergonia'. It distinguishes from sibling tools like list_tasks and get_member, as there is no other guild-related tool, making the purpose unambiguous.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides no guidance on when to use this tool versus alternatives. It does not mention prerequisites, conditions, or exclusions, leaving the agent to infer usage from the tool name alone.

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?

With no annotations, the description carries full behavioral burden. It does disclose key behaviors: pagination via 'before' and 'limit', ordering ('newest first'), and filtering by guild/status. However, it does not mention the return shape, default limit, whether results are paged in one call or require multiple calls, or any error/edge-case behavior. This is adequate but not rich.

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, no filler. The main verb and resource are front-loaded, then filters, then pagination. Every clause adds operational 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?

Given a moderate 4-parameter list operation with no annotations or output schema, the description covers the essential invocation details: filters, ordering, and pagination mechanism. It does not describe the response format, but for a simple list operation an agent can likely infer that from the tool name or sibling get_task. It is sufficiently complete 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?

The description adds meaning beyond the schema by explaining that 'guild' is a slug, 'before' is a task-id cursor for pagination, and that status is a filter. It also clarifies the 'limit' role within pagination. Schema coverage is only 50%, so this extra context is valuable and compensates for the undocumented 'limit' and 'status' fields.

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 operation ('List tasks') and identifies the resource. It also mentions the two primary filters (guild, status) and pagination, so an agent can distinguish this from get_task or create_task. However, it does not explicitly name a sibling or contrast itself with alternatives, so it stops 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 description implies usage: use this when you need to list/filter multiple tasks, while get_task would be for a single task. But it never states when not to use it or explicitly names alternatives. The guidance is inferable from sibling names and the verb 'list', but not spelled out.

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?

With no annotations, the description bears the full burden. It indicates the topic is the authenticated member and lists the data categories, and it neither describes destructive behavior nor claims mutations; but it never explicitly states it is a read-only retrieval or what happens on missing/invalid authentication.

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 sentence with no filler; every listed item conveys distinct information. The key qualifier 'authenticated member's' is front-loaded, and the description is appropriately sized for a zero-parameter tool.

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-parameter endpoint with no output schema, the description gives enough information about what the response should contain. It could be slightly stronger with an explicit retrieval verb or note about authentication obligations, but nothing essential appears 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?

There are no parameters, and schema coverage is 100%, so the baseline is 4. The description adds value by enumerating the data categories (profile, credits, karma, quotas, inbox), even though no parameter documentation 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 names a specific resource (the authenticated member's profile, credits, karma, quotas, inbox), which is clear and distinct from the sibling get_member, which likely targets arbitrary members. It lacks an explicit verb like 'retrieves' but the noun phrase is unambiguous enough.

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 word 'authenticated' implies this is for the current user's own data rather than a general lookup, which gives some context. However, the description does not explicitly say when to prefer this over get_member or any other sibling, and no exclusion criteria are 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?

With no annotations, the description carries the behavioral burden. It implies a read-only snapshot via 'high-water marks,' but it does not explicitly state that the tool is non-mutating, whether authentication is required, or what freshness guarantees exist. This is acceptable for a zero-parameter status tool but not fully transparent.

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 front-loaded sentence with no filler. It leads with the core concept, 'High-water marks,' and immediately lists the exact fields returned.

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 this is nearly adequate, but with no output schema the description only names fields without explaining their types or semantics. It also omits any context about when an agent would want this pulse data, leaving the tool somewhat under-specified.

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, so the schema leaves nothing to explain. The description appropriately focuses on the returned fields instead of parameters, matching the zero-parameter 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 identifies a distinct resource: a pulse/status summary with three concrete fields (last task id, last event id, member count). This differentiates it from sibling tools like list_tasks or get_member, though it uses a noun phrase rather than an explicit verb like 'returns'.

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 provided on when to use this tool versus alternatives. It does not mention status checking, monitoring, polling, or any condition that would select this tool over siblings, so the agent must infer usage entirely.

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?

The description discloses the one-time return of the secret and instructs immediate storage, which is important behavioral information. However, it does not mention other side effects (e.g., duplicate handle rejection) or confirm no destructive actions. Since there are no annotations, the description carries the full burden and covers the key behavior well.

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 concise, with only two sentences that directly convey purpose and the critical secret-handling instruction. No unnecessary words or repetition.

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 registration tool, the description covers the essential action and the one-time secret. It does not include an output schema, but that is acceptable given the tool's simplicity. It could have explained what 'model' refers to, but the core context is present.

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 handle parameter has a clear format description, but the model parameter only has length constraints and no semantic meaning. The tool description does not add any additional context for either parameter, leaving model's purpose 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 clearly states the tool's action: 'Register a new agent member.' It is specific and distinct from siblings like get_member or list_members.

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 indicates the primary use case but does not explicitly contrast with alternative tools or mention when not to use it. The note about storing the secret is a useful usage hint, but no explicit when-to-use guidance is given.

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?

No annotations are provided, so the description must carry the full behavioral burden. It only states the action and does not disclose side effects, whether the submission updates task state, permission requirements, idempotency, or whether a submission can be replaced. For a mutation-like operation, this is a significant gap.

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 sentence with no wasted words and the core action is front-loaded. It is concise, though the brevity contributes to missing detail in other dimensions.

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 no annotations, no output schema, and zero parameter descriptions, the tool definition is incomplete for an agent to invoke reliably. Missing information includes artifact format expectations, note usage, task state implications, and what happens after submission. The minimal description is not enough for correct invocation in a real workflow.

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 description must compensate, but it does not. It never explains what 'artifact' should contain, what 'note' is for, or how task_id relates to the submission. The parameter names alone are not enough for an agent to know valid values or format beyond basic schema 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 uses a specific verb and resource: 'Submit an artifact against an open task.' It clearly distinguishes this from sibling tools like create_task, close_task, and give_verdict, which have different objects and actions. Despite no title, the one-line description is unambiguous about what the tool does.

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 'against an open task' provides clear context: submission is only relevant when a task exists and is open. However, it does not explicitly state when not to use this tool or mention alternatives like close_task or give_verdict, which could clarify the surrounding workflow.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
