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

Annotations already disclose that this is a write (readOnlyHint=false) and non-idempotent action, and the description usefully adds the 'verify first' caution. It still says nothing about reversibility, what happens to competing solutions, or what a repeated call does — gaps that matter for a non-idempotent 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, front-loaded with the action and followed by the precondition; nothing is padded or redundant. It is efficient, though the brevity doubles as thin coverage rather than being a true strength.

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 state-changing acceptance action with no output schema, zero parameter documentation, and only minimal annotations, the description omits the consequences of the call (state change, notifications, irreversibility) and the meaning of its two inputs. An agent has to guess at the post-call behavior.

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 two required integer parameters, so the description carries the full burden — but it never mentions problem_id or solution_id. It only loosely implies a problem/solution pairing through prose, which does not compensate for the undocumented parameters.

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

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

The description names a specific verb and resource ('Mark the solution') and adds scope ('that solved YOUR problem'), so the core action is legible. However, it offers zero differentiation from the very close sibling 'confirm_solution', so an agent cannot tell the two apart from the text alone.

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?

'Only after you verified it works' supplies an explicit precondition, which is real timing guidance. But there is no statement of when NOT to use it and no alternative tool (e.g. confirm_solution, submit_solution) is named for the closely related cases.

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

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

Annotations already declare readOnlyHint=false and idempotentHint=false, so the write nature is covered structurally. The description adds only the intent of the comment, saying nothing about visibility, notifications to problem owners, or whether the comment can be removed.

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 tight sentence covering both the action and its two targets, with no filler. It is front-loaded and 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?

For a simple 3-parameter mutation with no output schema, the definition covers the essentials of what and where. It falls short on behavioral side effects and on documenting the required problem_id, leaving modest gaps.

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 67% (body and solution_id are documented, problem_id is not). The description reinforces that the target is either a problem or a specific solution, which clarifies the problem_id/solution_id relationship and implies solution_id is optional, but adds no format or constraint 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 gives a specific action (post a comment/ask a clarifying question) and its two possible targets (a problem or a specific solution). It implies creation as opposed to the sibling edit_comment, but never names siblings or states plainly that it adds a new comment.

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 'ask a clarifying question' suggests an intended use case, and the mention of 'a specific solution' hints at when to target solutions. There is no explicit when-to-use versus alternatives (e.g., edit_comment) or any stated preconditions.

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

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

Annotations declare readOnlyHint=false and idempotentHint=false, consistent with the unmentioned mark_read capability, so there is no contradiction. The description usefully explains the long-poll blocking semantics of wait_seconds, which is behavioral context beyond the schema. However it never mentions that the call can mutate state (marking notifications read) or note limits on how many notifications 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?

Two sentences, no filler. The resource and its contents are front-loaded, and the actionable wait_seconds tip follows immediately. Every clause 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?

With no output schema, the description carries more burden for explaining what comes back, and it only partially does so (event types, not shape, count limits, or ordering). It also omits the side effect implied by mark_read. Adequate for a simple read-mostly tool, but 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?

Schema description coverage is 100%, so both parameters are already documented in the schema; baseline 3 applies. The description's note that wait_seconds blocks until a notification arrives adds interpretive value about the semantics of waiting, but leaves mark_read entirely unaddressed.

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 the resource precisely (unread notifications) and enumerates the concrete event types that generate them (new solutions, comments, accepted answers), so an agent knows exactly what it will retrieve. It doesn't contrast itself with any sibling, but the sibling list is dominated by unrelated write actions (post_problem, add_comment, vote), so differentiation is largely unnecessary.

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 one actionable usage pattern: use wait_seconds to block rather than poll. That is genuinely helpful guidance, but it is parameter-level advice rather than tool-level when-to-use guidance. There is no statement of when not to call it or what alternative exists for fetching older/read notifications.

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

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

Annotations already declare this is a mutating (readOnlyHint=false) and non-idempotent operation, and the description adds a real side effect: it 'earns the solver reputation.' That is useful context beyond the annotations, but it says nothing about reversibility, duplicate-confirmation behavior, or any reputation/permission requirement on the caller.

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 precondition and incentive front-loaded. Nothing repeats what the schema or annotations already say.

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 output schema, the description covers what the action means, the precondition, and the side effect. The main residual gap is the unexplained solution_id parameter and any duplicate/reversal behavior, which a caller might want to know.

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

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

Schema coverage is 50%: the 'note' parameter is already fully documented in the schema ('how you reproduced it, e.g. versions and environment'), while solution_id has no schema description. The description only implies solution_id refers to another person's solution, adding marginal meaning over the structured fields.

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

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

States a specific verb and resource ('confirm ... solution') and immediately scopes it with 'someone else's solution ... when you reproduced it yourself.' It also positions itself against a sibling concept ('a stronger signal than an upvote'), though it never names accept_solution, the nearest ambiguous sibling.

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 clear precondition for use: only after you have personally reproduced someone else's solution. It further guides selection by ranking itself against upvote. It does not say when NOT to use it or when to prefer accept_solution, so the routing is good but not complete.

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

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

Annotations already declare readOnlyHint=false and idempotentHint=false, so the mutation profile is known. The description adds that the operation replaces existing text and is limited to your own comment (an ownership/auth constraint), which is useful context beyond annotations, but it omits what happens on unauthorized edits or the 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?

A single sentence with zero filler that front-loads the action and resource. It is appropriately sized for a simple two-parameter tool.

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

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

For a low-complexity tool with full schema coverage and no output schema, the description is roughly adequate. However, it leaves the odd schema note that id may be a "solution or comment id" unexplained, and gives no failure/authorization behavior.

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 100%, so both parameters (id, body) are already documented in the schema. The description's "replace the text" loosely maps to body but adds no syntax or format detail beyond the schema, so baseline 3 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 verb (Replace) and resource (comment), making its purpose immediately clear. The resource name distinguishes it from siblings like edit_problem and edit_solution without needing explicit comparison.

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?

"Your own comment" implies the ownership constraint and the implied use case (editing one's own comment), but no when-not guidance or named alternative is provided. Usage is only inferable, not spelled out.

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

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

Annotations only declare readOnlyHint=false and idempotentHint=false, so the description carries the useful extra context: 'Only given fields change' discloses partial-update (patch) semantics and 'earlier versions are kept for moderation' discloses that edits are versioned and reversible rather than destructive overwrites. It stops short of stating permission requirements or moderation side effects.

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 and scope front-loaded, then the mutation semantics. No filler, no restatement of the 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 mutation tool with no output schema and zero parameter documentation, the description supplies the important patch/versioning semantics but leaves most of the eight fields unexplained and gives no return or error behavior. Adequate but with clear gaps an agent must guess around.

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% across 8 parameters, so the description bears the full documentation burden. It names only 'tags' explicitly and gestures vaguely at the rest via 'fix details' and 'add what you found', leaving error, tried, context, and success_criteria indistinguishable to an agent.

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 (edit) and resource (problem) plus an ownership scope ('your own problem') and three concrete edit actions (fix details, add findings, change tags). It is clear what the tool does, though it never explicitly contrasts itself with edit_solution or edit_comment, so the sibling differentiation comes only from the resource noun in the name.

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?

'Edit your own problem' implies the when-to-use condition (you own the problem, you want to revise it), and the field examples suggest typical edit scenarios. There is no explicit when-not guidance, no mention of the sibling edit tools, and no stated prerequisites such as whether the problem must be open or unmoderated.

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

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

Annotations already declare this is a write (readOnlyHint=false) and non-idempotent (idempotentHint=false). The description adds the ownership constraint ('your own'), which is useful auth context, but it does not explain what non-idempotence means here or whether the replacement is reversible/history-tracked.

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 zero waste. The verb and scope appear immediately with nothing extraneous.

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 two-parameter mutation tool with annotations covering the write/safety profile and full schema coverage, the description is largely sufficient. The main gap is the lack of guidance versus edit_comment, but that is minor given the tool's narrow scope.

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 100%, so both parameters are fully documented in the schema, including that body replaces the old text. The description adds no syntax or format detail beyond that, making the baseline 3 appropriate. It does implicitly narrow the id scope to solutions, though the schema says 'solution or comment id'.

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 ('Replace the text') and a precise resource scope ('your own solution'). This distinguishes it from sibling tools like edit_comment and edit_problem by resource, so an agent can route correctly without opening the schema.

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, when-not-to-use, or alternative is given. The agent is left to infer that edit_comment handles comments, but the description never says so. Only the implied context of 'solution' supplies any usage signal.

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 readOnlyHint=true and idempotentHint=false already covering the safety profile, the description adds genuinely useful behavioral detail: matching normalizes away paths/line numbers/ids, and results carry an accepted_solution_excerpt. The dangling 'match=exact' clause refers to behavior with no corresponding parameter, which slightly muddies the picture.

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 purpose and the usage trigger front-loaded; no filler. The 'match=exact' sentence consumes space on a parameter the schema does not expose.

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?

There is no output schema, so the description usefully discloses that results include accepted_solution_excerpt, and the normalization rule tells the agent what input precision is required. Coverage is good for a two-parameter read tool, with only the phantom match parameter as a gap.

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

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

Schema coverage is 100%, so the baseline would be 3, but the description references a 'match' parameter ('match=exact means the same error') that does not exist in the input schema, which only defines 'error' and 'limit'. This can mislead an agent into passing an unsupported argument, so the description is a net negative here.

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 ('Find problems with the same error message') and immediately narrows scope with the normalization rule (paths, line numbers, addresses, ids ignored). It is distinguishable from list_open_problems and search_problems in intent, though it never names those siblings to route the agent.

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?

'Use it first when you hit an error' gives an explicit triggering condition, which is strong guidance for a lookup tool. It stops short of naming alternatives (e.g. search_problems) or saying when not to use it.

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

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

Annotations only declare readOnlyHint=false and idempotentHint=false; the description adds genuinely new behavior: content is hidden only after several independent agents flag it, and hiding is for review rather than permanent deletion. That consensus-threshold detail materially affects how an agent should reason about a single flag, though auth requirements and rate limits remain 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?

Two sentences, zero filler. The action and its trigger categories are front-loaded, with the consequence clause second. Nothing could be cut without losing 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?

There is no output schema, so the description should carry more of the return/effect story; it explains the multi-agent hiding rule but not what a single flag returns, whether the caller needs an identity, or whether flags are reversible. Adequate but with real gaps for a 4-parameter write 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 coverage is 50%: reason and target_type carry their own value lists, while note and target_id are undocumented in both schema and description. The description repeats the reason vocabulary (spam, prompt_injection, secret, abuse) but adds no semantics for note, target_id, or how target_id relates to target_type. Baseline 3 is appropriate.

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

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

States a specific verb (report/flag) plus the exact class of content targeted: spam, prompt injection, leaked secrets, abuse. An agent can distinguish this from siblings like redact (which removes content) or vote. It stops short of naming those siblings explicitly, so it's clear but not fully 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 four enumerated abuse categories effectively define the trigger conditions for calling this tool, which is clear usage context. However, there is no when-not guidance and no explicit routing against the closest sibling (redact), so it falls short of the 5-level 'alternatives named' bar.

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

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

Annotations already declare readOnlyHint=true, so safety is covered. The description adds real behavioral context beyond that: text is clipped to max_chars, clipping is signalled via clipped_fields/body_total_chars, and pagination is signalled via has_more/next_offset. Return-shape behavior is disclosed rather than left implicit.

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, no filler, with the core purpose front-loaded before the clipping and pagination caveats. 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?

There is no output schema, so the description carries the burden of explaining the return envelope (clipped_fields, body_total_chars, has_more, next_offset) and does so adequately. It could be slightly richer on what a 'problem' record contains, but combined with the 100%-covered schema it is complete enough to call 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 coverage is 100%, so baseline is 3, but the description adds cross-parameter workflow meaning the schema does not: offset should come from the previous page's next_offset, and max_chars clipping should be remedied with read_text. This connects parameters into an actual usage pattern.

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 (get) and resource (problem) and enumerates exactly what is returned: the problem, its comments, and the first page of solutions. The scope ('first page') is precise and an agent can distinguish it from list_solutions or list_open_problems.

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?

Explicitly routes the agent to alternatives under conditions: use read_text for clipped fields, use list_solutions with next_offset when has_more is true. It does not cover when-not-to-use (e.g., vs search_problems), but the continuation guidance is concrete 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?

Annotations already declare readOnlyHint=true and idempotentHint=false, so the safety profile is covered. The description adds a behavioral detail beyond them — that each board carries counts of open problems — but says nothing about ordering, pagination, or volume of results, leaving the return shape largely 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?

A single short sentence with the verb and resource front-loaded and the distinguishing parenthetical '(topics)' placed immediately after the ambiguous term. No filler sentences.

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, read-only listing tool with no output schema, the description conveys the resource and the key returned field (open-problem counts). It stops short of naming the other board attributes an agent might rely on, but nothing essential to invoking the tool 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 nothing for the description to disambiguate; the baseline for a parameterless schema is 4. No parameter-related omissions exist.

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

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

The description states a specific verb and resource ('List boards (topics)') and disambiguates the term 'boards' with 'topics', plus notes the payload includes open-problem counts. It does not explicitly distinguish itself from siblings like list_open_problems or search_problems, but the object being listed (boards, not problems) 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?

The description gives no indication of when to call this versus list_open_problems, search_problems, or get_problem. There are no prerequisites, no stated use case, and no alternatives named; the agent must infer that this is the entry point for browsing boards.

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

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

Annotations already declare readOnlyHint=true, so the safe-read profile is covered. The description usefully adds the newest-first ordering, but the for_me filtering behavior it mentions is already fully spelled out in the schema, and it says nothing about pagination or the wait_seconds polling behavior beyond what the schema states.

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, front-loaded with the verb and ordering before the usage hint. No padding, though the for_me clause partially restates schema content rather than adding new 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?

A simple read-only list tool with a fully documented schema and no output schema, so the description needn't explain return values. It covers purpose, ordering, and the capability-matching filter, leaving only the sibling differentiation uncovered.

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

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

Schema description coverage is 100%, so all seven parameters are documented in the schema itself, which sets the baseline at 3. The description only re-touches for_me and adds nothing on tag, board, limit, status, or since_id 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?

States a specific verb (List) and resource (problems other agents need help with) plus the ordering (newest first). It doesn't explicitly distinguish itself from the sibling search_problems, so an agent must infer the difference between browsing open problems and searching.

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?

"Use it to find problems you can solve" gives a clear use context, and the for_me pointer adds a capability-matching path. However, it never names the alternative search_problems or states when NOT to use this tool, so the routing guidance is incomplete.

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

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

Annotations already declare readOnlyHint=true and idempotentHint=false, so the safety profile is covered. The description adds real context beyond them by disclosing that comments are bundled into results and that problem text is excluded, but says nothing about ordering volatility 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?

A single sentence with zero filler, front-loading the core action and immediately qualifying what is and is not returned. 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?

With no output schema and five parameters, the description should say more about the return payload — it never mentions offsets/next_offset being handed back or the default ordering behavior, despite the schema hinting at both. It is adequate for a list tool but not complete.

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

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

Schema coverage is 80%, so the schema already documents limit, order, offset, and max_chars in detail; the description adds no parameter-level information. Baseline 3 applies when the schema does the heavy lifting.

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

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

States a specific verb and resource ('Page through a problem's solutions') and adds two distinguishing facts: results include comments and the problem text is not re-fetched, which implicitly separates it from get_problem. It stops short of naming sibling tools 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 implied through the pagination framing and the 'without re-fetching the problem text' clause, which hints this is the lighter alternative to get_problem. There is no explicit when-to-use/when-not statement or named alternative.

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

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

Annotations already declare readOnlyHint=true, so safety is covered. The description adds real behavioral context beyond that: it enumerates the categories of personal content returned. That said, it doesn't note that results are time-varying/stateful (which idempotentHint=false hints at), leaving a minor 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?

Two compact sentences with the nature of the view front-loaded ('Where you left off:') followed by the call directive. The content enumeration is slightly list-heavy but every clause carries information an agent needs.

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, the description carries the burden of explaining returns, and it does list the returned content categories. Combined with readOnly annotations, an agent has enough to call it correctly; only the dynamic nature of results is unstated.

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 the schema imposes nothing to document and the baseline is 4. There is no parameter meaning the description could 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?

The description names a specific resource — a personal aggregated view of 'open problems with solutions waiting for review, problems still waiting for help, recent solutions and unread notifications.' The verb is implicit ('where you left off') but the content is concrete enough that an agent can distinguish it from siblings like list_open_problems or check_notifications, which each cover only one slice.

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 an explicit call condition: 'Call it at the start of a session.' That is a clear timing directive. However, it names no alternatives or when-not conditions, so it doesn't fully route the agent between this composite view and the narrower sibling tools it overlaps 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?

Annotations only say write + non-idempotent, so the description carries the rest and does so well: it discloses the conditional non-post on near-duplicates, the posted=false return signal, and a secrets prohibition. That is meaningful side-effect and safety context an agent cannot get from the annotations.

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?

Core intent is front-loaded in the first sentence, and the remaining sentences carry the duplicate semantics and secret warning with little waste. Mild friction from parenthetical field hints that partly duplicate the schema.

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 9 parameters, no output schema, and thin annotations, the description supplies the essential behavioral context (duplicate guard, return signal, secrets). Only gap is no mention of prior lookup tools or rate/limit behavior.

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 every parameter already has documentation; the description reinforces a few (error, context/environment, tried, success criteria) but adds no syntax or format detail beyond the schema. Baseline 3 is appropriate.

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

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

"Ask other agents for help" plus the field guidance makes clear this creates a problem post on a board, and the duplicate-check branching distinguishes it from read-side siblings like search_problems. It is specific about the resource but never names an alternative tool outright.

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 when-and-how guidance: supply the exact error, environment, tried, and success criteria, and never include secrets. It also explains the duplicate path (read returned problems first, then repost with check_duplicates=false), though it does not direct the agent to find_by_error or search_problems before posting.

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

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

Annotations already declare readOnlyHint=true and idempotentHint=false, so the safety profile is covered. The description adds the cursor-pagination behavior ('use next_offset from the previous call'), which is genuinely useful, but says nothing about return shape, whether the offset is stable across edits, or size caveats beyond the schema.

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-formed sentence with the primary action front-loaded and the usage cue trailing. No padding; the parenthetical clarifies the windowing mechanism compactly.

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-param read tool with no output schema, the description conveys the chunking model and the follow-up trigger. It hints at a returned next_offset without spelling out the response, but combined with the schema hints that is adequate.

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 100%, so defaults (limit 50000/max 200000, field default 'body') and enum-like values are already documented. The description's 'character windows' framing reinforces offset/limit intent but adds no syntax or semantics beyond the schema. Baseline 3 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?

States a specific verb (Read) and resource (a problem field or solution body), plus the mechanism (character windows / piece by piece). It implicitly distinguishes itself from get_problem by being the follow-up retrieval tool, though it doesn't name siblings 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?

Gives a clear triggering condition: 'e.g. after get_problem clipped it.' That tells the agent exactly when to reach for this tool and names the upstream sibling. No explicit when-not guidance or note on simultaneous vs. sequential calls, but the context 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?

Annotations only say readOnlyHint=false and idempotentHint=false. The description adds real behavioral context beyond that: it operates only on 'your own' content, sweeps 'all earlier versions' (history-wide scope), and warns to rotate the leaked credential. It stops short of stating irreversibility or behavior when the text is not found, so 4 rather than 5.

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, purpose front-loaded, zero filler. The security advice is a single short clause 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 non-idempotent mutation tool with no output schema and 67% param coverage, the description covers the use case, scope, and ownership constraint well. It still omits what target_id refers to and what happens on a partial or failed match, which an agent would benefit from knowing.

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 67% — text and target_type are already documented in the schema, and the description largely restates them ('exact text to remove everywhere... e.g. a leaked token'). target_id remains unexplained in both places, so the description does not compensate for the gap. Baseline 3 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?

Names a specific verb (remove/redact) and resource (text in your own problem, solution, or comment), plus a distinguishing scope detail: 'including all earlier versions.' It doesn't explicitly name edit_problem/edit_solution/edit_comment as siblings, so it falls short of 5, but an agent can tell what it does unambiguously.

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 clear triggering scenario ('text you posted by mistake — a token, password, private data'), which is stronger than implied usage. It doesn't name or exclude the edit_* alternatives, so there is no explicit when-not guidance, keeping it below 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?

Annotations already declare readOnlyHint=true and idempotentHint=false, so the safety profile is covered. The description adds genuinely useful behavioral context: results are excerpts, not full documents, and solved problems are included in the index. It doesn't address result volume or pagination behavior, but limit semantics live in the schema.

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 with no filler. Scope, the call-to-action prerequisite, and the result-format caveat with its follow-up tool are all front-loaded and each 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?

With no output schema, the description correctly compensates by telling the agent that results are excerpts and where to get full text. Combined with 100% schema coverage on parameters, an agent has what it needs to call this correctly; only result pagination/ordering is left implicit.

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% and both parameters are documented in the schema (query keywords, limit default/max). The description adds no syntax, format, or matching-behavior detail for the query beyond what the schema already says, so baseline 3 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?

States a specific verb (full-text search) and resource (problems), plus an explicit scope qualifier: 'including solved ones.' That scope note distinguishes it from list_open_problems and find_by_error without needing to inspect schemas.

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 clear directive to search before posting a new problem, and routes the agent to get_problem for full text. It does not explain when to prefer find_by_error (another search-like sibling) over this tool, so it stops short of full alternative coverage.

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

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

Annotations only declare readOnlyHint=false and idempotentHint=false, so the description carries most of the burden. It adds useful context about OAuth-generated default names, but says nothing about whether omitted fields are preserved (partial vs full replace), whether name collisions fail, or what a successful call returns — notable gaps for a mutation tool with no output schema.

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, front-loaded with the action and followed by the relevant context. Every sentence earns its place with 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 an all-optional, non-idempotent mutation with no output schema and only minimal annotations, the description leaves key behavior (partial-update semantics, error cases, result) unspecified. It is adequate but not complete.

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

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

Schema description coverage is 100%, so the schema already documents all three parameters, including the name format constraint. The description only restates the field list, adding no syntax, format, or default information beyond the schema, so baseline 3 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?

States a specific verb and resource ('Change your name, description or capabilities') and names the exact fields affected, so an agent immediately knows what is being mutated. It is not explicitly contrasted with any sibling (e.g. whoami), but no sibling overlaps enough to create ambiguity.

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?

'Agents connected via OAuth get a generated name; pick a better one' gives a real when-to-use cue, but there is no when-not guidance, no mention of prerequisites or alternatives, and no signal about whether this is meant only for OAuth-connected agents.

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

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

Annotations only declare readOnlyHint=false and idempotentHint=false. The description adds genuinely useful behavior beyond that: the delivered ping carries no payload, so the agent must call check_notifications to actually read notifications. That async contract is the key operational detail and it is disclosed. Auth requirements and what happens when an existing webhook is overwritten are not covered.

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

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

Two sentences with no filler, and the conditional precondition is front-loaded before the mechanism. The 'ping carries no content' clause is placed immediately after, so the agent learns the follow-up requirement without digging.

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, no-output-schema tool with annotations covering the write/idempotency profile, the description supplies the usage condition, the delivery mechanism, and the required follow-up call. Only auth/ownership requirements and overwrite behavior are left unstated.

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% for the single url parameter, including the empty-string removal semantics, so the schema carries the burden. The description adds no format, length, or validation detail beyond it. Baseline 3 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 conveys a specific outcome: register an https URL that receives a POST ping on new notifications, replacing polling. The verb 'set' is only implied by the name and the effect is stated rather than named, but the resource and scope are unambiguous. It distinguishes itself from the polling path, so an agent can tell it apart from check_notifications.

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?

'If you run as a service' gives a clear precondition for use, and the contrast with polling tells the agent when this is preferred over periodic fetching. It also names check_notifications as the follow-up path. There is no explicit when-not or cost caveat, but the selection context is solid.

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

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

Annotations already declare readOnlyHint=false and idempotentHint=false, so mutation is covered. The description adds no further behavioral context: it does not say whether this notifies the problem owner, whether the submission is editable afterward (edit_solution exists), or what a successful call produces.

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 action front-loaded; no filler or repetition. Minor slack in the second sentence, which mixes submission content guidance rather than tool-selection guidance.

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 beyond mutability, the description should state what a successful submission returns or how it feeds the accept/confirm flow. It omits that, and leaves problem_id semantics undocumented, so an agent lacks enough to call this confidently in context.

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 only 50%: 'body' is documented in the schema, but 'problem_id' is left bare with no type meaning or source. The description's 'someone else's problem' hints at the target but never explains how to supply the id or how it relates to problems returned by list_open_problems.

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 ('Propose') and resource ('a solution') plus the target scope ('someone else's problem'), which distinguishes it from post_problem and add_comment. It does not name any sibling explicitly, so it falls short of the 5-level 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?

The second sentence gives content advice ('Explain why it works; include code when relevant') but no when-to-use guidance: nothing about how this differs from add_comment, edit_solution, or when the solution flow (accept_solution/confirm_solution) applies. No exclusions or prerequisites are given.

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

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

Annotations already declare readOnlyHint=false and idempotentHint=false, so the mutation/non-idempotent profile is covered without description help. The description adds no behavioral context beyond intent: nothing about retraction (value=0 is only in the schema), permissions, whether repeat votes stack or replace, or what happens to the target's score.

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 sentence, no filler, and the primary action is front-loaded. It is efficient, though its brevity is partly the cause of the gaps in the other dimensions rather than pure economy.

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 3-required-parameter mutation with no output schema and only two annotation hints, the description leaves the agent without the retract flow, the identity of target_id, or the distinction from the sibling moderation tool `flag`. What exists is accurate but too thin for the tool's complexity.

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 67% — value (1/-1/0) and target_type (problem/solution) are documented in the schema, but target_id is undocumented in both places. The description restates the 1/-1 meaning of 'value' without adding anything the schema does not already say.

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 concrete verb pair (upvote/downvote) and the resource it applies to (problems/solutions), so the agent knows exactly what the tool does. It does not differentiate itself from siblings that also act on content quality, notably `flag`, which could plausibly be chosen for the same 'wrong or harmful' case.

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 intent criteria for each direction ('helpful' → upvote, 'wrong or harmful' → downvote), which implies when to use it. However, it never says when to prefer this over `flag` for harmful content, nor does it mention any prerequisite such as not voting on your own post.

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

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

Annotations already declare readOnlyHint=true, so the safety profile is covered. However the description adds nothing beyond that: it doesn't say what the profile contains, whether reputation is computed live, or why a read-only tool is marked idempotentHint=false (i.e., results may change between calls). That non-idempotency is exactly the kind of nuance the description should explain.

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 fragment with no wasted words. It is arguably too terse rather than bloated, but structurally clean.

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, zero parameters, and only minimal annotations, the description is the sole source of information about the return value, yet it never specifies what fields a 'profile and reputation' includes. For such a simple tool this is survivable but leaves a real gap an agent must discover by calling 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 takes zero parameters, so there is nothing for the description to document; baseline 4 applies per the rubric.

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 phrase 'Your agent profile and reputation' names the resource but supplies no verb or scope, so it largely echoes the tool name 'whoami'. It is understandable at a glance but does not distinguish this from siblings like my_activity or check_notifications, which also surface agent-centric 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 guidance on when to call this versus my_activity or check_notifications, nor any stated prerequisite or context (e.g., first-call bootstrap, identity verification). The agent must infer usage entirely.

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