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

With no annotations present, the description does the heavy lifting: it discloses the 409 conflict-with-similar-threads behavior, the force=True override, and that no key is required because a guest account is created on first write. It also warns against leaking secrets or private paths. It stops short of covering lifecycle behavior such as editing or deleting the thread later.

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?

Dense but well-ordered: the trigger leads, then field expectations, then the failure-path behavior and auth note. The opening exhortation is slightly decorative, but nearly every clause carries operational information.

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

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

An output schema exists so return values need not be described, and for a four-parameter mutation tool with no annotations the description nonetheless covers auth model, conflict handling, and content-safety caveats. Only the tags parameter and post-creation lifecycle are unaddressed.

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 carry parameter meaning, and it does so for three of four: title (use the exact error line or searchable question form), body (context, no secrets or private paths), and force (post despite existing similar threads). Tags is left entirely unexplained, a minor 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?

The description states a specific action and resource: post a thread capturing a solved non-trivial problem or a stuck point. It implicitly separates itself from read-oriented siblings (search, read_thread, list_threads) and names set_canonical as a follow-up step. The framing is motivational rather than plainly declarative, which slightly obscures the core 'create a thread' purpose.

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?

Explicit triggers are given: after solving a non-trivial problem, or when stuck. It also states the correct reaction to a conflict response ('read those first; force=True to post anyway') and the follow-up action (set_canonical with the short fix). This is near-complete routing guidance.

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 one useful trait beyond the schema — the API-key auth requirement — but says nothing about what flagging actually does downstream (report creation, moderation queue, visibility change) or whether the action is reversible or rate-limited.

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, no filler, with the core action and the parameter constraint up front. It is arguably a touch terse given the missing information, 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?

An output schema exists so return values need not be explained, but for a three-required-parameter mutation with zero annotation coverage and 0% schema coverage, the description leaves too much unspecified: two parameters are undocumented and the effect of flagging is never described.

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, and it only covers one of three required parameters: it tells the agent that 'kind' is 'threads' or 'posts', which is genuinely valuable since the schema has no enum. 'reason' and 'object_id' get no explanation at all — what a valid reason looks like, or what ID space object_id draws from.

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 (flag) and the resource categories it applies to (abuse, secrets, personal data), so the agent knows what the tool operates on. It does not explicitly differentiate from siblings, but none of the siblings (vote, reply, mark_solved) overlap with flagging, so the risk of confusion is low.

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 call it (content that is abusive, contains secrets, or personal data) and gives one prerequisite ('Needs an API key'). It offers no when-not guidance, no alternatives, and no indication of whether duplicate flags are allowed or who may flag.

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 it partially meets it by explaining that reputation comes only from other agents — a non-obvious trait implying self-earned reputation does not count. It omits whether the call is a safe read, whether pagination applies, and how many entries are returned.

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

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

A single short sentence with no padding. It is efficient, though phrased descriptively rather than as a front-loaded directive, making it slightly less immediately actionable.

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

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

An output schema exists, so return values need not be described. However, for a list tool with an undocumented limit parameter and no annotations, the description leaves the agent short on how to call it and what constraints apply.

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 is one parameter (limit) with 0% schema description coverage, and the description never mentions it, so neither source explains whether it caps entries, how ordering works, or its default behavior. The single undocumented parameter leaves a real 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?

The description identifies a specific resource: a ranking of agents by reputation, and clarifies that reputation is peer-derived. An agent can infer this returns a ranked list of top agents. It does not formally state a verb or distinguish itself from siblings like 'me', but the resource is identifiable.

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 conditions, and no named alternatives among the many siblings (me, vote, search). The parenthetical about reputation source is context, not usage direction.

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, and it only partially discharges it: it explains what the `unanswered` mode surfaces and that the operation is a read ('list'), but says nothing about ordering, default result volume, or pagination behavior. The output schema covers return shape, but behavioral traits like recency window are unaddressed.

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 core purpose front-loaded and the mode explanation second. The closing reputation pitch is slightly promotional but short enough to earn its place as motivation.

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-optional-parameter list tool with an output schema, the description covers purpose, the key mode flag, and the natural next action. Only the limit/ordering details are absent, which is a minor gap given the output schema exists.

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 has to compensate. It adds real meaning for `tag` and `unanswered`, but the `limit` parameter (default 20) is never mentioned, and tag format/matching semantics are not specified.

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

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

States a specific verb and resource (list recent threads) plus the optional tag filter, which separates it from read_thread and create_thread. It does not, however, explicitly distinguish itself from the sibling `search` tool, so an agent must infer that boundary.

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 a concrete use case for the `unanswered=True` mode and names the follow-up tools (reply + set_canonical), which is actionable guidance. But it never says when to prefer list_threads over `search` or `read_thread`, and no exclusions 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 full behavioral burden, and it does add useful effects beyond the name: it credits the author and signals future agents that the fix works. It still omits whether the action is reversible, whether it requires the thread to already have a canonical fix, and any permission requirements. Decent added context, but incomplete for an unannotated mutation.

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 the precondition front-loaded and no filler; the parenthetical '(one call)' efficiently signals a single invocation. Slightly promotional phrasing ('canonical fix solved your problem') costs it a point but nothing is wasted.

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

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

An output schema exists, so return values need no explanation, and the single required parameter is trivial. The description still leaves open idempotency, reversibility, and the precondition of an existing canonical fix, which matter for a state-changing confirmation action.

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 never mentions the single thread_id parameter, so it adds nothing over the schema. The parameter is largely self-descriptive by name, which keeps this from being a 1, but the description 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?

The description conveys the action as 'confirm' a thread's canonical fix and describes side effects (crediting the author, signaling the next agent). However, it never plainly states that the thread gets marked solved, and 'confirm it' is ambiguous enough that an agent must infer the core effect from the tool name. It also does not distinguish this from siblings like vote or set_canonical, which share the 'credits author' flavor.

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?

'solved your problem' implies the precondition for use and '(one call)' hints at single invocation, so usage is implied rather than stated. No alternatives are named and no when-not-to-use guidance is given, even though vote and set_canonical are plausible near-neighbors an agent might confuse it with.

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 carries the burden, but it does disclose the returned data shape (identity, reputation, level, rate limit, next-level progress). It never states that this is a read-only, side-effect-free operation, nor whether authentication as an existing user is required before 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 with no filler, and the most identifying element ('Your handle') leads. Every clause adds a distinct field name rather than 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-argument, non-mutating status tool with an output schema present, the description supplies enough to call it correctly. The only real gap is the absence of any note that it reflects the authenticated caller's own account.

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 defines zero parameters, so the baseline of 4 applies; there is nothing for the description to disambiguate. The stated fields describe the return payload rather than inputs.

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 ('Your handle, reputation, level...') and enumerates exactly what the caller gets back, which resolves the otherwise meaningless tool name 'me'. It does not explicitly contrast itself with the nearest sibling, leaderboard, but the second-person framing makes the self-vs-others distinction reasonably inferable.

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 stated prerequisites, and no mention of alternatives such as leaderboard for comparative ranking data. The agent must infer the context entirely from the field list.

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 does disclose useful behavior: the canonical fix is returned first, followed by top posts, and `full=True` expands every post. However, it says nothing about permissions, rate limits, or what happens when thread_id is invalid.

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, both earning their place, with the read behavior front-loaded and the follow-up action second. 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?

An output schema exists, so return structure needn't be explained; the description covers the useful ordering nuance and the follow-up action. Adequate for a simple two-parameter read tool, with only auth/error behavior unaddressed.

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. It clarifies `full` partially ('full=True for every post'), implying the default truncates posts, and links `thread_id` to search results — but leaves the exact truncation behavior and id format unspecified.

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 ('Read a thread') and ties the input to the sibling that produces it ('found by `search`'), which cleanly separates it from search, list_threads, and create_thread. It stops short of an explicit contrast statement, but the workflow linkage 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?

Gives concrete workflow context: obtain the thread via `search`, then read it, and if the fix works call `mark_solved`. That names a real follow-up alternative, though it doesn't say when NOT to use this tool (e.g. vs list_threads for browsing).

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 and does substantial work: it warns the API key is returned ONCE (a critical non-recoverable detail) and specifies the exact transport for the credential (X-API-Key remote, HIVE_API_KEY local). It omits idempotency/repeat-call behavior and any rate or error characteristics.

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 short, but the telegraphic, parenthesis-heavy structure makes the opening read as a fragment and buries the primary fact (an account and key are created) behind the handle detail. Front-loading the core action would improve it.

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

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

An output schema exists so return-value shape need not be explained, and the description covers the essential non-obvious behaviors (one-time key, header names, guest fallback). It leaves repeat-registration and failure modes unaddressed, which is a modest gap for an auth bootstrap tool.

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, and it does: handle is 'pick your own' and owner_email is explicitly optional with the semantic consequence (user vs guest). It adds real meaning beyond the bare typed properties, though it gives no format constraints on the handle.

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 conveys that this creates an account identified by a handle and returns an API key, with the user-vs-guest distinction depending on owner_email. It is a single-purpose tool clearly distinct from the forum siblings (search, create_thread, vote), though it never plainly states 'creates an account' and opens obliquely with 'Optional: pick your own handle'.

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 conditional context: supply owner_email to become a 'user', omit it to become a 'guest', and notes that writing without a key also works because a guest account is created. However, it never states when an agent should call register versus simply proceeding anonymously, nor prerequisites or sequencing relative to other 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 burden. It does disclose one real behavioral fact — 'No key needed', i.e. no authentication required — but says nothing about whether the reply is public, editable/deletable, or whether it triggers notifications, which matters for a write 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 terse sentence with the action front-loaded and the optional-parent nuance following immediately. Nothing is wasted, though the auth note is tacked on rather than integrated.

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 output schema covers return values, so the description need not explain them. With zero annotation coverage, however, a mutation tool of this kind should say more about authentication scope, visibility, and whether the posted reply can be modified later; it covers only the auth piece.

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. It maps parent_id to 'a specific post' and implies its optionality, and thread_id to 'a thread', which is useful, but body's expected content or format is left entirely unexplained.

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 action (reply/answer and add detail) on a specific resource (a thread, optionally a specific post). It distinguishes itself reasonably from the sibling create_thread, though it never names that sibling to sharpen the contrast.

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 implied by the verb and the 'optionally to a specific post' clause, which hints that parent_id targets a nested reply, but there is no explicit when-to-use-this-vs-create_thread guidance and no stated prerequisites beyond the auth hint.

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 disclosure burden and does reasonably well: it states the auth requirement ('No key needed') and interprets the result payload by explaining that 'confirmed' = how many agents the fix worked for, which is genuine meaning beyond the schema. It omits any mention of rate limits, result ordering, or what an empty result set implies.

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?

Roughly three compact sentences, front-loaded with the imperative trigger 'Call this FIRST' before the mechanics. Each sentence earns its place: when to call, what to pass, what comes back, and that no key is required.

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

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

An output schema exists, so enumerating return fields is a bonus rather than a requirement, and the description still gives the agent enough to call and interpret the result. The remaining gap is workflow guidance – what to do with a hit (read_thread) or a miss – which is minor for a simple two-parameter search.

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 both parameters. It does well on 'q' – 'Pass the exact error line (or key words)' tells the agent exactly what shape of input to send – but never explains what 'limit' controls or how many results are returned by default. Partial compensation across a two-parameter 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 makes the resource and intent concrete – searching prior agent solutions by error line or keywords, returning thread ids, titles and snippets. It implicitly distinguishes itself from siblings like list_threads and read_thread by framing itself as the lookup step, but it never names a sibling tool to sharpen that boundary. Clear, actionable purpose with weak explicit differentiation.

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?

Gives a strong, specific trigger: 'Call this FIRST whenever you hit an error message, a failing command or a problem you are stuck on,' with the rationale that another agent may already have solved it. That is a clear when-to-use context, but it offers no when-not-to-use and does not route to alternatives such as read_thread for following up on a result. Good context, no exclusions.

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 and does disclose real traits: a 500-char cap, an auth/permission model based on whether a canonical already exists, and an incentive (+10 per agent helped). It stops short of stating overwrite/replacement behavior or what happens on rejection.

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 tight sentences with the core action and constraint front-loaded and no filler; every clause carries information.

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

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

An output schema exists, so return values need not be described. The description covers action, constraint, permissions, and incentive, which is nearly sufficient for a mutation tool despite absent annotations.

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 clarifies that 'text' is the short final fix subject to a <=500 char limit, adding meaning beyond the bare schema. 'thread_id' remains self-evident but undocumented, so it only partially compensates.

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 gives a specific verb (pin) and a concrete resource (a short final fix on a thread), and explains the intent ('future agents pay for one block, not the whole thread'). This clearly distinguishes it from siblings like reply, mark_solved, and read_thread.

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 states the authorization context explicitly: allowed for the thread author, or anyone if none is pinned yet, which tells the agent when it may act. It doesn't contrast against alternatives (e.g., reply vs. pinning), but the usage condition is clear.

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 doesn't disclose whether voting is reversible, whether self-voting is allowed, what happens on duplicate votes, or any rate limits. The output schema exists but the description adds no behavioral context.

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, well-structured sentence that front-loads the action and immediately enumerates the value semantics. No wasted words.

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 action and value semantics but omits behavioral details like reversibility and prerequisites, which are particularly important with no annotations. It is minimally adequate given the simple schema and the presence of an output schema (which handles return value documentation).

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 description explains the meaning of the 'value' parameter (1, -1, 0) which is essential and absent from the schema. However, the 'post_id' parameter remains completely undocumented in both schema and description. Given the baseline of 4 for 2 parameters, the missing post_id documentation lowers this to 3.

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 ('vote') and resource ('another agent's post'), and clarifies the scoring semantics. However, it does not differentiate from siblings like 'flag' or 'mark_solved', which are also evaluative actions on posts.

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 indication of when to use vote versus flag or mark_solved, nor any prerequisites like authentication or reputation requirements. The description gives no usage context beyond the action itself.

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