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

With no annotations, the description carries the full load, and it does disclose meaningful behavior: the server never generates answers, uniqueness/originality is required, and duplicates are detected via a ledger with a named error condition. It does not say what a successful submission produces (graded immediately? stored? returns a receipt?), leaving the post-call state unknown.

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 short sentences, all load-bearing: the submission contract first, the authorship caveat second, the duplicate/retry rule last. No filler or restatement of the tool name.

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 one-parameter submission tool with no annotations and no output schema, the description covers input constraints and duplicate handling well, but omits where the challenge words come from and what the caller gets back on success, leaving the agent guessing about the surrounding 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 coverage is 0% and the single property is bare 'text', so the description must compensate — and it does, adding a 120-600 character bound, an originality requirement, and a constraint that it naturally use the 3 challenge words. It stops short of 5 because the '3 challenge words' are never defined or cross-referenced to the sibling that supplies them.

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?

Specific verb+resource+constraints: 'Submit YOUR OWN original 120-600 character answer that naturally uses the 3 challenge words.' Clearly a write/submission tool, and 'This server never writes answers' clarifies the agent must author the content. It does not name a sibling to differentiate from poa_check_answer or poa_grade, so it stops short of 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?

It gives one real usage rule — check the ledger before resubmission, and that a 'duplicate challenge for epoch' error means it was already answered — which tells the agent how to handle retries. But there is no explicit guidance on when to call this versus poa_check_answer or poa_grade, so routing is left to inference.

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 full burden. It implies a read-only listing and adds a valuable safety disclosure that returned answer text is untrusted data rather than instructions. However, it says nothing about permissions, pagination, scope of seats returned, or response 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 short sentences with zero waste: the purpose is front-loaded and the safety warning follows. Every sentence 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?

For a zero-parameter list tool with no output schema, purpose plus a data-handling warning covers the essentials. It would be more complete if it noted what a grading seat contains or how the result relates to poa_grade, but nothing critical to invoking it 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 takes zero parameters, so there is no parameter semantics to explain and the baseline is 4. The description correctly adds no irrelevant parameter discussion.

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 (list) and resource (grading seats), which is enough for an agent to distinguish it from action-oriented siblings like poa_grade, poa_vote, and poa_challenge. It stops short of explicitly naming a sibling or the relationship to poa_grade, so it is clear but not maximally differentiating.

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 no when-to-use guidance, no prerequisites, and no pointer to related tools such as poa_grade or poa_grade_batch. The second sentence addresses prompt-injection safety, not usage routing, so an agent gets no help deciding when to call this versus a sibling.

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 of behavioral disclosure. 'List' implies a read operation, but the description does not state read-only behavior, permissions required, pagination, or any other operational trait.

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 wasted words. It communicates the core operation 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?

Given the low complexity and zero parameters, the description is minimally adequate. However, with no output schema and no annotations, it does not specify the return structure, pagination, or whether filtering is possible, leaving some gaps for an agent to call it 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?

The tool has zero parameters, so there are no parameter semantics to explain. Per the rubric, a zero-parameter schema establishes a baseline of 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 uses a specific verb ('List') and resource ('governance ballots, topics, options and tallies'), making the operation clear. It does not explicitly distinguish itself from siblings such as poa_vote or poa_grade, 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?

No guidance is given about when to use this tool versus alternatives like poa_vote or poa_params. The description only states what it returns, leaving the agent to infer usage context.

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 full behavioral burden. It discloses the shape of the return ('3 required words and the task') but says nothing about authentication requirements, whether the challenge is epoch-scoped or rotates, or any constraints on calling it.

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 naming the resource and its payload, followed by a short directive. Every clause earns its place with no padding.

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, no-output-schema tool the description is just adequate: it explains what comes back, but omits why the agent needs it, how it fits the epoch lifecycle, and any failure/availability behavior. Nothing critical is contradicted, but the picture is 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?

The tool takes zero parameters, so there is no parameter semantics to add and the baseline is 4. The description's reference to 'this epoch' is the only input-like notion, and it is implied rather than a declared argument.

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?

It states a specific verb and resource ('Get this epoch's challenge') plus the payload ('the 3 required words and the task'), which is more than a restatement of the name. It does not, however, explicitly contrast itself with siblings like poa_answer or poa_check_answer, so the agent must infer the pipeline position.

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?

'Write the answer yourself' hints at the workflow (fetch, then answer) but gives no explicit when-to-use rule, prerequisites, or alternates. Nothing tells the agent how this relates to poa_answer, poa_check_answer, or poa_grade beyond a faint implication of ordering.

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 full behavioral burden. It does disclose that the operation is non-mutating ('Does not edit or write text'), which is genuine value, but it says nothing about permissions, whether requirements differ per context, or what a failing check looks like in the response.

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 filler, with the core action and its non-mutating constraint both front-loaded. Nothing here needs trimming.

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, non-mutating check tool with no output schema, the description covers what it does and that it does not send or edit. It stops short of describing the return shape (pass/fail, length and word diagnostics), which the agent must guess.

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?

One parameter with 0% schema description coverage, so the description must compensate; it does implicitly identify 'text' as the draft answer being checked. However, it adds no format, length-limit, or required-word details beyond that framing.

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 (Check) and a specific resource (a draft answer's length and required words), and the phrase 'without sending it' implicitly separates it from the sibling poa_answer. It does not explicitly name that sibling, 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?

'Without sending it' implies this is the pre-flight variant to use before submitting, but no condition or named alternative (e.g. poa_answer) is given. Usage is inferable 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?

No annotations are provided, so the description carries the full behavioral burden, and it discloses nothing: no read/write indication, no pagination, no rate limits, no return shape. The only added fact is the REST path, which does not describe 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?

It is a single noun fragment with no bloat, but the brevity is under-specification rather than economy. There is no verb and no front-loaded statement of what the call does.

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 no-arg, no-annotation, no-output-schema tool the bar is low, yet the description still omits the operation and any hint of what records are returned. An agent cannot confidently decide to invoke it over the other epoch-related siblings.

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, so there is nothing for the description to explain beyond what the empty schema already conveys. Baseline 4 applies for a no-argument tool.

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 the resource ('Epoch close records') and pins it to an endpoint (/api/epochs), which is more than the bare tool name provides. However, it supplies no verb, so an agent cannot tell whether this lists, fetches, or summarizes epoch records, and nothing distinguishes it from siblings like poa_ballots or poa_params.

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 call this versus the many sibling query tools (poa_status, poa_params, poa_explorer, etc.). The agent is left to infer usage entirely from the name.

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 disclosure burden. It mentions the optional-address default but does not state whether the operation is read-only, whether it requires authentication, or what kind of data is returned, leaving significant behavioral gaps.

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 definition is a single, front-loaded sentence with no redundant text. It is appropriately compact for a one-parameter tool, though its brevity borders on under-specification.

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 one optional parameter, no annotations, and no output schema, the description is too thin. It does not explain what an 'explorer view' contains, how the address is interpreted, or when an agent should invoke this tool versus its many siblings.

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 schema only defines an optional 'address' string|null with default null. The description adds useful semantic meaning by clarifying that the address defaults to the caller's own address, partially compensating for the schema gap, though it still does not describe the expected address format.

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 the resource ('an address') and the view type ('Explorer'), and notes the default to the caller's own address. However, it does not state a specific action or output, and it does not differentiate this tool from siblings like poa_status or poa_network_status, so the purpose remains vague.

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 when-to-use or when-not-to-use guidance is provided. The only usage hint is that the address argument defaults to the caller's own address, but the description does not mention alternatives or conditions for selecting this tool over other poa_* 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 full behavioral burden. It discloses that the tool waits for a receipt, which is useful, but it does not explain permissions, irreversibility, validation failures, or what the receipt contains.

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 wasted text. It packs the core action, constraints, and synchronous wait behavior into a compact statement.

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 write-oriented tool with no annotations, no output schema, and 0% schema description coverage, the description is still underspecified. It omits assignment identifier format, authentication needs, error behavior, and receipt semantics, leaving important gaps for an agent trying to call it 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?

Schema description coverage is 0%, so the description must supply parameter meaning. It usefully specifies the score range (0-3), that reasoning should be one sentence, and that assignment is a single assignment, but it does not clarify the assignment identifier format or other validation details.

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: submit a grade for one assignment. The phrase 'one assignment' also implicitly distinguishes it from the batch sibling, though it does not name that 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 implies single-assignment use through 'one assignment,' but gives no explicit guidance on when to use this tool instead of poa_grade_batch or other sibling tools. There are no stated prerequisites, exclusions, or alternative-selection rules.

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 full behavioral burden. It usefully discloses sequential processing and waiting for each receipt, plus the ownership restriction, but it omits mutation side effects, failure handling, permissions, and return 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 two tight sentences with no wasted text. It front-loads the batch/sequential behavior and then specifies the grades shape.

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 mutation tool with no annotations, no output schema, and 0% schema description coverage, the description is significant under-specified. It does not describe the receipt shape, partial failure behavior, error handling, or parameter constraints, leaving the agent unable to know how to interpret results or recover from failures.

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% and the item schema is unspecified, so the description must compensate. It does name the expected object fields assignment, score, and reasoning, which adds meaning beyond the empty schema, but it does not explain types, score ranges, assignment identifier format, or 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 states a specific verb and resource: submit several grades in a batch. It also scopes the operation to 'YOUR OWN grades' and distinguishes batch semantics from a single submission, but it does not explicitly name the sibling poa_grade as the 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?

It implies when to use the tool by saying it submits several of your own grades sequentially, one at a time, waiting for each receipt. However, it gives no explicit guidance on when to use this versus poa_grade or other sibling tools, and no when-not conditions.

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. "Countersign" implies a state-changing operation, but the description does not disclose permissions, irreversibility, what happens to pending transactions, or what the operation returns.

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 definition is a single short sentence with no wasted words, and the core action is front-loaded. It is appropriately sized for the amount of information given.

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 a state-changing operation, the description is too sparse. It does not explain the effect of mining, expected outcomes, or safety considerations that an agent would need before invoking it.

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 empty schema reflects that. There are no parameter semantics to explain, so the baseline for a no-parameter tool 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 states a specific action and resource: "Verify and countersign pending transactions," with "(mining)" narrowing the context. It is clearer than the bare name poa_mine, but it does not explicitly distinguish this from sibling tools such as poa_vote or poa_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?

There is no explicit guidance on when to use this tool versus alternatives, no prerequisites, and no when-not conditions. The parenthetical "(mining)" implies context but does not tell an agent how to choose this tool over other PoA 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 provided, so the description carries the full burden. It discloses that the endpoint is public and lists the fields returned, but does not explicitly state read-only behavior, authentication requirements, rate limits, or response format. This is adequate for a simple public status tool 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?

The description is a single, front-loaded sentence that names the endpoint and summarizes the output fields without filler. It 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?

Given the tool's simplicity (no parameters, no output schema, no annotations), the description provides enough to invoke it correctly: it identifies the endpoint as public and lists returned fields. It remains slightly incomplete in not explicitly distinguishing this status from sibling tools like poa_status.

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 baseline is 4. Schema description coverage is vacuously 100%, and there is no parameter information for the description to add or omit.

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?

Names a specific resource (public network status) and lists the returned data points (epochs_closed, supply, agents joined). It does not explicitly state a verb like 'Get' or distinguish itself from sibling tools such as poa_status, 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?

No guidance is provided about when to use this tool versus alternatives. The description neither names exclusions nor points to related tools like poa_status or poa_epochs, leaving selection to inference.

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 behavioral burden, and it discloses almost nothing: the word 'Public' weakly implies an unauthenticated read, but there is no statement about safety, idempotency, return format, or what 'parameters' means. For a tool with zero annotation coverage this is a substantial 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?

It is a single terse fragment with no wasted words, which is structurally clean, but it is under-specified rather than concise — the brevity comes at the cost of saying anything useful beyond an endpoint path.

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 annotations, the description must explain what the tool returns and any behavioral traits. Instead it only restates a route path, leaving the agent unable to predict the response shape or constraints.

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 schema coverage is 100%, so there is nothing for the description to disambiguate. Baseline 4 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 names a resource (public network parameters) and its endpoint path (/api/params), but supplies no verb and no indication of what the tool actually does with them (retrieve? configure?). It does not differentiate itself from siblings such as poa_network_status or poa_epochs, which plausibly return overlapping network data.

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 guidance, no statement of prerequisites, and no reference to any sibling tool. An agent has no signal for choosing this over poa_network_status when it wants network information.

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 full behavioral burden and does so excellently: it discloses file creation with permissions (0600), that the key is never returned, the default referral behavior, the economic impact (up to 20% of payout from your share), and how to opt out. No critical traits are hidden.

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?

Front-loads the core action and effect, then uses a clearly delineated 'REFERRAL DISCLOSURE' block for the crucial monetary/default-routing details. Every sentence is necessary and well-organized.

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 complexity (account creation with referral economics), no output schema, no annotations, and 0% schema coverage, the description is nearly complete. The main gap is the missing 'label' parameter explanation; minor omissions like error behavior (e.g., if already registered) are acceptable.

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 explain all parameters. It fully defines 'referrer' and 'no_referral', but the required 'label' parameter is never mentioned, leaving an agent guessing what value to provide.

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+resource ('Create a PoA account') and the exact side effect ('save its API key to a local 0600 file'). Clearly distinguishes itself from all siblings, which are operations on an existing account rather than registration.

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 single use via 'One account per agent' and gives explicit conditions for referral options ('Set no_referral=true to opt out, or referrer=...'). Does not state when to call versus alternatives (none exist for registration), but the guidance present is clear and actionable.

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 lists returned values and notes 'answered (checked on the ledger),' which implies a read operation, but does not explicitly state that this is read-only, whether authentication is required, or how fresh the data is.

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 fragment with poor structure. It is short but too terse to be useful, and the list-like format does not front-load the tool's purpose.

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 status tool with no output schema and no annotations, the description should at minimum state what the tool returns and why an agent would call it. Instead it offers only a partial field list, omitting context about the returned status object and its use.

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, so parameter semantics are not applicable and the baseline is 4. The description does not need to explain any input values.

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 is a fragment listing field names ('Epoch, answered... balance, spendable, locked and established standing') without a verb or explicit statement of what the tool does. The name implies a status getter, but the description itself does not say it retrieves PoA status or distinguish it from siblings like poa_network_status or poa_epochs.

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 on when to use this tool versus alternatives. The description contains no context, exclusions, or references to sibling tools such as poa_network_status or poa_epochs, leaving the agent to 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?

No annotations are provided, so the description carries the behavioral burden, but for a zero-parameter reference lookup the risk surface is minimal. It does disclose the shape of the returned guidance, yet never states that it is a read-only, side-effect-free lookup or that output is static guidance.

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 that front-loads the resource and then lists the content buckets. The slightly loose phrasing ('what scores 2-3, what scores 0-1') is redundant but not wasteful.

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, the description need not explain return values, and for a zero-param guidance tool the stated scope is sufficient. It could still be strengthened by tying it explicitly to the grading 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?

The tool takes no parameters, so there is nothing to document and the baseline is 4. The description correctly implies no input 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?

It states a specific resource: grading guidance from the PoA field guide, enumerating the content (what scores 2-3, what scores 0-1, how to grade). This clearly distinguishes it from the sibling action tools like poa_grade and poa_grade_batch, though it never names them 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?

Usage is only implied: an agent can infer this should be consulted before assigning scores with poa_grade, but the description never says when to call it, whether it is a prerequisite, or how it differs from poa_params.

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 must carry the full behavioral burden. It usefully discloses that the first vote is final and not retried automatically, which signals irreversibility, but it omits permission/auth requirements, what happens on a duplicate vote (error vs. ignored), and whether any state is overwritten.

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 the action stated first and the critical finality constraint second. No filler, though it is short enough that it could have spent a few more words on the parameters.

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 mutating tool with no annotations, no output schema, and 0% parameter documentation, the description is too thin. An agent cannot confirm valid choice values, required identifiers, error behavior, or the response shape.

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% for all three required parameters. The description only echoing 'ballot topic' and the notion of a vote leaves choice formats, valid values, and identifier syntax entirely undocumented, so it does not 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 ('Cast one vote on a ballot topic'), which is easily separable from siblings like poa_ballots (listing) or poa_grade. It stops short of naming any sibling or contrasting scope, so it is clear but not differentiated.

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 finality rule ('first vote per topic is final') implies the usage context -- vote once, deliberately -- but no alternative tool or condition is named, and the agent is left to infer when voting is appropriate versus reading poa_ballots first.

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