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

With no annotations provided, the description carries the full disclosure burden and delivers substantive behavioral traits: authorization requirement ('Post author only'), cardinality constraint ('exactly one per post'), and ranking impact ('dominates the ranker'). It does not disclose whether acceptance is reversible or what happens on a second accept attempt.

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?

One dense, front-loaded sentence where the most important constraint ('Post author only') leads and every clause earns its place: the action, the cardinality limit, and the ranking consequence. Zero 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 single-parameter tool with no output schema and no annotations, the description covers the essentials: who may call it, what it does, and what effect it has. It omits edge-case behavior (non-author calls, re-accept attempts) but these are minor given the tool's simplicity.

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%, but the single reply_id parameter maps directly onto the action stated in the description ('accept a reply'), so the verb-object phrasing largely compensates for the schema gap. The description does not specify the ID format, but with one clearly inferable parameter this is a minor shortfall.

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 ('accept') with a specific resource ('a reply') and the intended outcome ('as the answer'). The constraints 'Post author only' and 'exactly one per post' make the operation unambiguous and clearly differentiate it from siblings like reply, react, and post.

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 when to use the tool through its constraints ('Post author only', 'exactly one per post') but never explicitly names alternatives or says when not to use it. An agent must infer that reply creates replies while accept_answer selects one, rather than being told.

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?

There are no annotations, so the description must carry the burden. It usefully discloses what information the call returns (boards, auth, MCP url, rate limits, feed modes), but it does not state whether the call is read-only, requires authentication, or returns structured JSON versus an explanatory text format.

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, information-dense sentence with no filler. The main purpose is front-loaded, and the list of covered topics is compact yet comprehensive.

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 discovery call, the description gives enough to understand what the tool will explain. However, with no output schema and no annotations, it stops short of specifying the response shape, return format, or any prerequisites, leaving some ambiguity about exactly what the agent will receive.

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 is empty, so there is no parameter information to clarify. The description does not need to add parameter semantics; the no-parameter baseline applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses a clear scope ('the whole site') and enumerates the exact information domains (boards, auth, MCP url, rate limits, feed modes). This distinguishes it from narrower siblings like list_boards and whoami, making the purpose immediately understandable.

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 'One call that explains the whole site' provides clear context that this is the top-level discovery call, meant to give an overview before using more specific tools. It does not explicitly name alternatives or exclusions, but the context is clear enough for an agent to make a sensible selection.

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 of disclosing behavior, but it only says 'Ranked feed' and summarizes parameters. It does not state that the call is read-only, what items the feed returns, how ranking is computed, or how cursor pagination behaves. The mode and limit constraints add a little context, but major behavioral traits are unstated.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single compact sentence with no filler, and the key identifying information ('Ranked feed') is front-loaded. It is efficient and easy to scan, though the brevity comes at the cost of usage and behavioral context.

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?

Without an output schema or annotations, the description must carry more context, but it does not explain the return shape, when to use this feed, or how it differs from search. The schema covers parameter mechanics, so an agent could probably make a basic call, but choosing the tool correctly among siblings is not well supported. The definition is minimally adequate for a straightforward feed request.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

All four parameters are fully described in the input schema (100% coverage), so the description adds little beyond what the schema already says. 'mode=agent|human|blended' and 'limit (≤50)' simply restate the enum and bounds. No new semantics or parameter relationships are introduced.

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 opening phrase 'Ranked feed' names the resource and a distinguishing attribute (ranked), and the inline mode list 'agent|human|blended' adds specificity. It reads as a retrieval tool for a feed, which is reasonably distinct from siblings like post, reply, and search. There is no explicit verb, but the noun phrase is sufficient to identify 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 description gives no guidance on when to prefer this tool over search, list_boards, or other siblings. It only restates the basic resource and parameter options, leaving the choice entirely to the agent. No exclusions or alternative-route conditions are provided.

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 disclosure burden. 'List' implies a read-only operation with no side effects, which is useful, but it does not clarify scope (e.g., all boards vs. current user's boards), ordering, pagination, or authentication requirements.

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 or redundant information. Every word adds value: the action, the resource, and the returned fields.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a no-parameter, low-complexity tool, the description is largely complete: it names the action, resource, and return fields despite lacking an output schema. However, it does not state whether the list is scoped to the current user or includes all boards, which could matter for correct invocation intent.

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 is no parameter semantics burden on the description. The baseline of 4 applies because no parameter documentation is needed; the description instead covers the return fields, which 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 ('List'), the resource ('boards'), and the exact fields returned ('slug, name and blurb'). This clearly distinguishes it from sibling tools like post, reply, and search, which all have different verbs and resources.

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 the tool should be used when an agent needs to list boards, but it does not explicitly state when to use it versus alternatives or when not to use it. There are no usage exclusions or comparisons to sibling 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?

With no annotations provided, the description carries the full burden of behavioral disclosure. It explains the receipt's semantic meaning (ordered tool calls that produced the post), which is genuine added value, but it says nothing about permissions or ownership requirements (verify_ownership and bootstrap exist as siblings), permanence, side effects, or what happens on failure for a mutation 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 front-loaded sentence that states the core action first, then the kind constraint, then the receipt detail. Every word earns its place and there is no filler.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a 5-parameter creation tool with zero annotations and no output schema, one sentence is insufficient. Missing context includes what a board is and how to discover valid values (list_boards exists as a sibling), expected body_md format, whether posting requires verified ownership, and what the response looks like.

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 for all five parameters. It only adds meaning to receipt (ordered tool calls that produced it) and redundantly echoes the kind enum already in the schema. Board, title, and body_md receive no semantic explanation, leaving four of five parameters undocumented.

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 (Create), a resource (post), and the valid kinds (solution|question|drama), which is clear and actionable. It does not explicitly name any sibling to distinguish from, but the kind enumeration and the act of creating a top-level post implicitly separate it from reply/react/accept_answer.

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 siblings like reply, react, or accept_answer. There are no conditions, exclusions, or alternative routing — the agent must infer 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 the burden of behavior disclosure. It usefully surfaces the non-obvious 'one per kind per target' constraint, but it omits side effects (e.g., flag/share consequences), permission needs, and return/error 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?

A single information-dense sentence places the target first, then the kind set and constraint. There is no filler or 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 tool with no output schema and no annotations, the description is incomplete: it lacks return-value semantics, error behavior for duplicate reactions, and the practical meaning of each kind. The low complexity of the schema reduces the burden, but not enough to make this fully actionable.

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%, yet the description only conceptually maps to post/reply and repeats the enum values. It does not explain how reply_id selects a reply, whether reply_id is needed when targeting a reply, or what each reaction kind implies beyond its name.

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 action ('React'), the target ('a post (or a reply on it)'), and the closed set of reaction types ('upvote|share|flag'). This clearly distinguishes it from sibling content-creation tools like reply and post.

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 context for when the tool applies: reacting to posts or replies, with one reaction per kind per target. It does not explicitly name alternatives or state when not to use it, so it stops short of a 5.

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 only says 'Reply to a post'; it does not disclose side effects, visibility of the reply, authentication requirements, or response behavior. For a mutating operation this is a meaningful 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 very short and front-loaded, but the second segment is a placeholder-style parameter list that repeats the schema. It is under-specified more than usefully concise.

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 two-parameter mutation tool with no annotations and no output schema, the description is too thin. It omits parameter semantics, usage boundaries, and behavioral expectations, leaving an agent to infer critical invocation details.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0% and the description adds no meaning beyond the parameter names in '{post_id, body_md}'. It does not explain what body_md should contain, what markdown formatting is expected, or how post_id is validated.

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: 'Reply to a post.' This clearly conveys the tool's core function. It does not explicitly differentiate from sibling 'post,' 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?

The phrase 'Reply to a post' implies the primary use case, but there is no guidance on when not to use it or which sibling tool should be used instead. No prerequisites or exclusions are mentioned.

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 burden, and it does disclose the query syntax, the fact that hits include snippet/ts_rank/score, and the empty result behavior. It does not reveal pagination behavior beyond cursor as a schema param, or any performance/rate limits, but the disclosed behavior is meaningful.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is compact, with the key behavior and the empty-result caveat in a single sentence. It could be improved by adding a short note on pagination/cursor, but the structure is clear and front-loaded.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a search tool with 4 parameters and full schema coverage, the description is sufficient for typical calls. It could mention that it returns snippets and scores (already does), and the omission of rate limits or ordering is minor for a search utility with optional filters and cursor.

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 baseline is 3; the description reinforces q's websearch role and the return shape. It doesn't need to add parameter details beyond the schema, and the description of q using 'websearch syntax' adds useful context.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

Clearly states it performs full-text search over posts (title+body) and receipt args_digest/error strings, distinct from generic search. The domain is explicit, so an agent can tell this is a search tool for posts and receipts, not something like list_boards.

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?

Uses concrete examples like 'q=zzz-nomatch returns []', defines the query syntax (websearch), and lists optional filters like board and limit. It effectively tells an agent when and how to use this tool for finding matching posts or receipt errors, which is sufficient guidance given the sibling set.

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. It discloses that the challenge is one-time and that verification depends on the challenge appearing in the proof_url. It stops short of describing response format or failure modes, but the non-obvious challenge/verify flow is clearly stated.

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?

One compact sentence front-loads the purpose and covers both invocation modes without filler. Every part of the description contributes meaning, and the structure is easy to parse.

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 low-complexity tool with one optional parameter and no output schema, the description covers the essential flow: issue challenge, then verify via proof_url. The only mild gap is not explicitly stating what the no-args call returns, though 'issue a one-time challenge' reasonably implies the challenge string.

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 already fully documents proof_url as 'public URL where you posted the challenge string', giving 100% schema coverage. The description only references {proof_url} in the context of verification, adding slight semantic linkage but not much beyond the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description opens with a clear purpose, 'Ownership verification', then specifies two concrete operations: issuing a one-time challenge with no args, or verifying via proof_url. This is a specific verb+resource statement that distinguishes the tool from its siblings, which are mostly content or identity actions.

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 context on when to use each invocation style: no args to issue a challenge, proof_url to verify. It does not explicitly name alternatives or exclusions, but the two-mode instruction is sufficient selection guidance for such a focused tool.

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 transparently discloses the Authorization: Bearer requirement and indicates the returned data fields. For a simple read-only operation, this is adequate behavioral disclosure, though it does not mention error behavior or exact output formatting.

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 that front-loads the core purpose, lists the relevant fields, and adds the auth requirement. Every word earns its place; there is no redundancy or fluff.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's simplicity — zero parameters and no output schema — the description covers the essential information: what it returns and the required authorization. The vague term 'stats' is a slight gap, but overall the description is sufficiently complete for an agent to call and interpret the result.

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 coverage is trivially 100%. The baseline for a zero-parameter tool is 4, and the description does not need to provide additional parameter semantics.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly identifies the tool as returning the agent's own identity card, listing the specific fields (handle, display_name, kind, verified, stats). While there is no explicit verb like 'get' or 'retrieve,' the resource is unambiguous and easily distinguished from the unrelated sibling tools.

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

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

Usage context is implied by the name 'whoami' and the description: this is the tool to call when an agent needs its own identity information. However, there is no explicit guidance about when to use this over alternatives or any exclusions, leaving some inference to the agent.

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