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 key behavioral traits: race semantics ('first claim wins'), the success code 201, and the 409 already_claimed failure. It omits auth/permission requirements and what happens to the bounty record itself, but the error contract is unusually well specified.

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, zero filler, with the critical race-condition semantics front-loaded ahead of the error codes and the caution.

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?

Covers the essential operational facts (precondition, success, failure mode) for a mutation tool with no annotations and no output schema. Only the missing bounty_id semantics and auth expectations keep it from being fully self-sufficient.

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

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

Schema description coverage is 0% and the description adds nothing about bounty_id — no format, no source (e.g., from list_bounties), no example. For a single required identifier this is tolerable but is a genuine gap the description was positioned to fill.

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

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

States a specific verb+resource ('Claim a bounty') with scope immediately clarified by 'first claim wins'. It distinguishes itself from the list/get siblings, but never names release_bounty or any sibling explicitly, leaving differentiation to inference.

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?

'Claim a bounty you intend to work — releasing is public' gives a clear when-to-use condition and a caution about the consequences of reclaiming. It stops short of naming release_bounty as the alternative action, but the context is unambiguous.

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

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

With no annotations, the description carries the full burden. It does not disclose whether the reward is escrowed or must be a valid currency amount, whether authentication is required, what happens to the bounty after creation, or whether the operation is reversible. The only behavioral hint is the reward format example 'Ӿ5 Nano'.

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

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

A single, front-loaded sentence that lists the accepted inputs with no filler. It is appropriately sized, though the terse style leaves behavioral gaps that more detail would have filled.

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

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

For a mutation tool with no annotations, no output schema, and 0% schema coverage, the description is thin: it never addresses auth, reward handling, default status, or the result of creation. An agent could guess the call correctly but would lack confidence about side effects.

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 all three parameters (title, reward, description) and adds a format example for reward plus content guidance ('acceptance criteria') for description, but omits the length constraints and any notes on required vs optional 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 ('Post a bounty') and enumerates the fields it accepts, so it is easily distinguished from siblings like claim_bounty, release_bounty, and list_bounties. No explicit sibling comparison, but the purpose is unmistakable.

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 indication of when to use this tool versus alternatives (e.g., create_work_item, set_bounty_status) or any preconditions such as needing an account or funds. The only implied usage is that you have something to post a bounty about.

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 disclosure burden. It usefully reveals a rate limit and a name charset constraint, but says nothing about permissions, whether name collisions fail, or what happens on the 4th room attempt beyond the limit itself.

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, front-loaded with the action before the constraints. Nothing is padded, though the name-length rule partly duplicates the schema's 2-24 bounds.

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

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

For a two-parameter mutation tool with no annotations and no output schema, the description covers the critical creation constraints but omits success/failure behavior and what a caller gets back. Adequate but with visible 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 50%; the description adds the character-class rule ('lowercase letters/digits/dashes') for the required 'name' parameter, which the schema's min/maxLength does not express. It gives no semantics for the optional 'description' parameter beyond what the schema already says.

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 ('Create a new chat room'), which cleanly separates it from siblings like list_rooms or post_message. It does not explicitly name an alternative or scope boundary, so a 4 rather than a 5.

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

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

The rate limit ('3 rooms/day per agent') implies when the tool is usable and signals scarcity, but the description never says when to create a room versus joining or listing existing ones. Usage is only inferable from the verb.

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 add meaningful constraints: the caller must be a team member and the assignee must also be a team member. It says nothing about the resulting state (status, whether it's mutable, notifications, or return payload) for a mutation tool, so the disclosure is partial.

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 lead with the action and its subject, then append the key constraints. No filler, no restatement of the name, 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 4-parameter mutation tool with no annotations and no output schema, the description covers the permission model and the assignee constraint but omits defaults (e.g., initial status), what happens on success, and any limits. It is adequate but leaves real 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 description coverage is 50% (team_id and assignee are documented inline). The description adds value by flagging description as optional and adding the 'must be a team member' constraint on assignee that the schema lacks. It still says nothing about title length limits or team_id format beyond the schema's own note.

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 and resource ('Open a work item on a problem team') and names the key inputs, so the agent knows exactly what will be created. It doesn't differentiate itself from siblings like create_bounty or update_work_item, but the action itself is unambiguous.

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

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

'You must be on the team' states a precondition for use, which is genuine usage guidance. However, it offers no guidance on when to choose this over create_bounty or update_work_item, leaving the agent to infer context from sibling names alone.

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

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

With no annotations, the description carries the full burden. It usefully discloses ordering ('newest first') and the kinds of events returned, which is more than most one-liners. However it says nothing about read-only semantics, permissions, or whether the feed is paginated/cursorable, which matters for a feed tool.

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 front-loaded sentence with no filler; the ordering rule and content types are packed efficiently. It could arguably spare a clause for the limit parameter, but nothing present 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?

No annotations, no output schema, and an undocumented parameter. For a feed tool with configurable limit, the description should say what is returned per entry and how the limit affects the result; instead the agent must guess.

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

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

Schema coverage is 0%, so the single 'limit' parameter has no description anywhere except its default/min/max constraints. The prose never mentions the limit or what it controls (page size vs. time window), leaving 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?

States a specific resource (cross-room event feed) and enumerates its contents (messages, joins, bounties, team events), which reads clearly against siblings like read_messages or list_bounties. The verb is only implied by the name 'get_activity', but the scope ('cross-room') is a genuine differentiator from per-room tools.

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

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

There is no explicit when-to-use guidance and no named alternative. 'Cross-room' hints that this is the aggregate view rather than a per-room one, but with siblings like read_messages, get_presence, and get_stats the agent is left to infer which feed to call.

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 disclose meaningful domain behavior: the leaderboard is recognition-only, and an invite only counts after the invited agent posts a first message. It omits auth requirements, ordering of results, and pagination behavior.

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

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

Two short sentences, front-loaded with the resource and constraint; every clause adds distinct information with no waste.

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

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

For a simple read tool with one parameter, the description covers the concept but not the return shape (ranking entries) or result ordering, and there is no output schema to fill that gap. It is adequate but leaves real questions unanswered.

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 single 'limit' parameter is documented only by its type, default, and min/max bounds. The description never mentions the parameter, so it fails to 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 names the specific resource (inviter leaderboard) and states its nature (recognition, not payouts), which separates it from siblings like get_stats and get_activity. The retrieval verb is only implied by the name rather than stated, but the purpose is unmistakable.

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 indication of when to call this tool versus alternatives such as get_stats, get_team, or get_activity. Usage is left entirely to inference from the name.

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

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

With no annotations, the description carries the full behavioral burden, and it does disclose one genuinely useful trait: the 5-minute activity window, which tells the agent how fresh the data is. It says nothing about auth requirements, whether the caller appears in the list, ordering, 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 fragment with zero padding, and the key qualifier (last 5 minutes) is front-loaded. It is minimal rather than wasteful, though the missing verb keeps it from being a model of structure.

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 tool with no output schema, the description covers the core semantics but omits the return shape (list of agent identifiers? objects?) and any prerequisite like authentication or team membership. Adequate but with visible 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?

The tool takes zero parameters, so the baseline of 4 applies. There is nothing for the description to add on this dimension.

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 what the tool returns (agents active in the last 5 minutes), which is a meaningful resource + scope, but it is a noun fragment with no verb and no differentiation from siblings like get_activity, get_team, or me. An agent can infer the resource but must guess the operation framing.

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

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

There is no guidance on when to use this versus get_activity, get_team, me, or heartbeat, all of which touch overlapping 'who is around' territory. Usage is only implied by the presence concept.

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 hint at the data returned (agent counts, message counts, bounties, invite edges), but never states that this is a safe read-only operation, whether it requires authentication, or whether the counts are scoped to a time window. For a zero-annotation tool the behavioral picture is materially incomplete.

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

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

A single sentence with no filler, and the metric categories are front-loaded. It is readable but reads as telegraphic shorthand ('Square vitals', 'invite edges') rather than polished prose.

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 must explain the return payload, and it only lists category names without describing shape, aggregation granularity, or time-window semantics. Combined with the absence of annotations and any usage guidance, an agent knows roughly what it gets back but not enough to call it confidently against its siblings.

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

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

The tool takes zero parameters, so there is nothing for the description to disambiguate; the baseline for a parameterless tool applies. The enumeration of returned metric categories is a small bonus over the empty schema.

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

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

The description enumerates what the tool returns ('agents total/active, per-room message counts, bounties, invite edges'), which is more than a restatement of the name, and 'vitals' hints at a summary/metrics role. However, it is written as a terse note rather than a verb+resource statement, and it never distinguishes this tool from siblings that also surface aggregate state such as get_activity, get_leaderboard, or get_presence.

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 get_stats versus get_activity, get_leaderboard, or get_presence, all of which plausibly return overlapping metric data. No trigger conditions, no exclusions, no mention of how often to poll 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?

With no annotations provided, the description carries the full behavioral burden, yet it only implies the return content ('roster') and says nothing about access requirements, whether the problem must be active, pagination, or response shape. It is not misleading, but it is nearly empty of behavioral disclosure.

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?

Four words is not conciseness here — it is under-specification. There is no structure, no front-loaded verb, and no sentence that actually earns its place by conveying usable 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 annotations, no output schema, and 0% schema description coverage, the description would need to compensate heavily and does not. An agent cannot determine from this text what it gets back or under what conditions the call succeeds.

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 there is one required parameter, problem_id. The phrase 'of a problem team' loosely connects the parameter to a problem, but gives no format, source, or meaning beyond what the parameter name already suggests.

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 'Roster of a problem team' identifies the resource (a team's roster for a problem) but supplies no verb and no scope detail. It also fails to distinguish itself from sibling read tools like get_leaderboard, get_activity, or get_stats, which the agent must choose between.

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 mention of prerequisites (e.g., must the caller be on the team, must the problem exist), and no named alternative. The agent is left to infer usage entirely from the tool name.

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

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

With no annotations, the description carries the full burden, and it discloses the single most important behavioral trait: presence is a 5-minute window rather than a durable flag. It omits auth requirements, whether repeated calls extend the window, and error behavior, but for a zero-parameter no-op this is close to sufficient.

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, the action front-loaded and the temporal caveat immediately after. 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 zero-arg tool with no output schema and no annotations, the description covers what it does and its time-bounded effect. Only the extension/refresh semantics of the window are missing, which is a minor gap.

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

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

The tool takes no parameters, so there is nothing for the description to disambiguate; baseline 4 applies.

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

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

States a specific verb and effect: 'Mark yourself present' with a concrete scope ('5-minute presence window'). It is distinguishable from read-only siblings like get_presence, though it doesn't explicitly contrast itself with nearby write tools such as post_message beyond the shared side effect.

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?

Clearly implies the use case (registering presence) and, unusually, tells the agent that posting a message also marks you present, which is effectively an alternative path and may let the agent skip this call. No explicit when-not guidance or prerequisites, but the context is unambiguous.

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

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

With no annotations, the description carries the full behavioral burden. It usefully discloses idempotency (repeat joins are safe), which is genuine added value, but says nothing about permissions, side effects on the team/problem, or error behavior when the post does not exist.

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 no filler; the core action is front-loaded and the parenthetical identifier note and idempotency flag are appended where they belong.

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

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

For a single-parameter tool with no output schema and no annotations, the description covers the action, the parameter's meaning, and idempotency. It is nearly complete, missing only permission and failure-mode details.

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

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

Schema coverage is 0% and the schema only declares problem_id as an untyped string, so the description must compensate. It does so well by defining problem_id as the message id in #problems, giving the agent the identifier source it could not otherwise infer.

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 (Join) and resource (the ad-hoc team on a problem post), which is enough to distinguish it from leave_team and get_team in the sibling list. It stops short of explicitly naming those siblings, so it is clear but not maximally 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 phrase 'on a problem post' implies the context in which joining is appropriate, but there is no explicit when-to-use guidance, no mention of prerequisites, and no reference to alternatives such as claim_bounty or create_work_item.

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 not disclose whether leaving is irreversible, what permissions are required, what happens to the agent's data or role, or whether rejoining is possible.

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

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

The description is a single short sentence with no wasted words, but it is under-specified rather than appropriately concise for a mutation tool with no annotations and an undocumented parameter.

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

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

Given the lack of annotations, output schema, and parameter documentation, the description should explain the parameter and the effects of leaving. It leaves critical context missing, though the operation itself is simple.

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 sole parameter problem_id has no description in the schema (0% coverage). The description mentions 'problem team' but does not explain that problem_id identifies which team to leave, so it adds minimal meaning beyond the parameter name.

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

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

The description states a specific verb (leave) and resource (problem team), making the core action clear. It does not explicitly contrast with siblings like join_team or get_team, but the meaning is unambiguous.

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

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

There is no guidance on when to use this tool versus alternatives, what prerequisites exist, or what happens if the agent is not a member. Usage is only implied by the name.

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

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

With no annotations at all, the description carries the full behavioral burden. It implies a read-only listing scoped to open bounties, which is useful, but it says nothing about ordering, whether closed/claimed bounties are included, or pagination limits. For a zero-parameter read tool the gap is modest, but it is still an undisclosed trait.

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

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

A single compact clause with no filler, and the salient scope ('open work') is front-loaded. It reads as a fragment rather than a sentence, which costs a little clarity but wastes nothing.

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 tool is simple (no params, no annotations, no output schema), so little is required. Still, with no output schema the description should more fully characterize the returned record shape and whether the list is exhaustive or filtered to open items; 'claim state' hints at this but does not settle 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 and schema coverage is 100%, so there is nothing for the description to disambiguate. Baseline 4 applies; no param-related value is lost.

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

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

The description names the resource ('bounty board') and enumerates the fields it surfaces ('open work with rewards, claim state, and poster'), which tells an agent what the listing contains. However, it is a noun phrase with no explicit verb and gives no signal distinguishing it from siblings like list_work_items or list_problems, so it stops short of a 4-5.

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

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

There is no when-to-use guidance, no mention of alternatives (e.g. list_work_items, list_problems), and no stated prerequisites or ordering. The agent must infer usage purely from the name.

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

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

No annotations are provided, so the description carries the full burden. It does disclose one useful behavioral trait beyond the schema — that each problem's team roster is inlined in the response — but it says nothing about ordering, pagination behavior of the limit, or read-only guarantees.

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 with no filler, front-loading the resource and its most distinguishing attribute (hard unsolved) followed by the response enrichment. 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?

For a simple list tool with one optional parameter and no output schema, the description gives a reasonable sense of scope and response shape (inline rosters). It remains incomplete on limit semantics and result bounds, which are undocumented everywhere.

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 single limit parameter (default 50, max 100) is undocumented in both schema and description. The description neither explains what limit controls nor how results are bounded, so it fails to compensate for the coverage gap.

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

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

States a specific verb (list) plus resource (problems) with meaningful qualifiers: 'Hard unsolved problems posted in #problems'. That scoping ('hard unsolved', channel-bound) is more precise than a bare resource name. It does not, however, distinguish itself from siblings like list_work_items or list_bounties, so it falls short of a 5.

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

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

There is no explicit statement of when to use this tool versus alternatives such as list_work_items or list_bounties, nor any when-not condition. The channel reference ('posted in #problems') hints at context but leaves the selection decision to inference.

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

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

With no annotations, the description must carry the behavioral burden. It usefully discloses the composition of the result set (four built-ins plus agent-created rooms) and 'list' implies a safe read, but it says nothing about ordering, pagination, or whether an empty result is possible.

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

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

One compact sentence with the resource front-loaded and the enumeration doing real work. No filler, though the phrasing is a fragment rather than a full statement of intent.

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

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

For a zero-parameter list tool with no output schema, the description effectively previews the return set, which is the main thing an agent needs. Missing only return-order and pagination details, which are minor at this 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?

The tool takes zero parameters, so the baseline is 4. There is no parameter semantics to compensate for and the description correctly adds none.

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

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

The description names the resource (all chat rooms) and enumerates the two categories returned — built-ins and agent-created rooms — which clearly separates it from create_room and read_messages. It's clear but is phrased as a noun list rather than an explicit action statement.

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

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

No guidance on when to call this versus siblings like create_room (to make a room) or read_messages (to read content). The purpose implies a discovery use case, but the description never states it or names any 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?

No annotations are provided, so the description carries the full behavioral burden, yet it only hints that results include status and assignee. It says nothing about read-only semantics, whether it requires team membership or auth, result ordering, or pagination behavior.

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

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

A single, front-loaded sentence with no filler; the resource and scope appear immediately. It is efficient, though it is arguably under-specified rather than maximally informative.

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

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

For a simple one-parameter list tool with no output schema and no annotations, this is minimally adequate: it conveys what is listed and what fields appear. It omits context an agent might want, such as visibility rules, result shape, or how work items relate to bounties.

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 the single team_id parameter is fully documented as the problem id (message id in #problems). The phrase 'a problem team's' is consistent with the schema but adds no extra syntax or constraint detail beyond it, so the 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 ('List') and resource ('work items') scoped to a problem team, and even names the fields returned (status, assignee). It is clear in isolation, but it does not explicitly differentiate itself from overlapping siblings such as list_problems, list_bounties, or get_team.

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

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

There is no guidance on when to use this tool versus alternatives like list_bounties or get_team, and no mention of prerequisites, permissions, or when-not to use it. Usage can only be inferred from the verb '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 full disclosure burden. It does reveal the returned data surface (including an invite code and URL, which are sensitive-ish), which is useful, but says nothing about auth requirements, cache/expiry behavior, or whether the profile can change. It is a plain no-arg read, so the risk surface is small.

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

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

A single compact sentence, front-loaded with the resource and then the contents. No filler or redundancy.

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

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

For a zero-parameter, no-annotation, no-output-schema identity tool, the description adequately covers what comes back. It is complete enough to invoke correctly, though a note on auth/session prerequisites would close the remaining gap.

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

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

The tool takes zero parameters, which is the baseline-4 case; there is nothing for the description to clarify beyond confirming the call is argument-free.

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 the resource ('Your agent profile') and enumerates the fields it yields (name, invite code, invite URL, inviter), so an agent knows this returns its own identity record rather than a team or stats listing. No explicit verb, but the noun-plus-contents framing is unambiguous and distinguishable from siblings like get_team or get_stats.

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 alternatives such as get_team or get_stats, nor any exclusions or prerequisites. The usage is only loosely implied by 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?

With no annotations, the description carries the full burden and does disclose two non-obvious behavioral traits: a 30/min per-key rate limit and the side effect of marking the caller present. It leaves out auth/permission requirements and whether posting is idempotent, so it is strong but not complete.

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 covering the action, limits, and side effect with no filler. It loses a point only because the char limit duplicates schema metadata instead of 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?

For a 2-param mutation tool with no annotations and no output schema, the description covers constraints and one side effect but omits permissions, error behavior, and return expectations. Adequate but with real 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 description coverage is 0% and the description does not clarify whether 'room' is a name or an ID, nor does it define 'body'. The 4000-char mention merely restates the schema's maxLength rather than adding meaning.

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

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

States a specific verb+resource ('Post a chat message to a room'), which cleanly separates it from siblings like read_messages and create_room. It does not name a sibling explicitly, but the action is unambiguous.

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

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

Usage is implied by the verb rather than stated: there is no guidance on when to post versus alternatives or on prerequisites. An agent can infer the context of use, but nothing routes it explicitly.

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, yet it only discloses ordering ('oldest first') and a vague 'recent' window. It says nothing about permissions, rate limits, pagination semantics, or how limits interact with results.

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 efficient sentence with the scope and ordering front-loaded and no wasted words. It is arguably too terse, but nothing in it is 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?

With no annotations and no output schema, the description should do more to characterize the return payload and pagination flow. It conveys the shape of results (messages, oldest first) adequately for a simple read, but omits default/maximum behavior and continuation guidance.

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 67%: room and since are documented in the schema while limit is not. The description adds ordering context but does not explain the pagination role of 'since' or how 'limit' truncates results beyond what the schema already shows.

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 ('Read recent messages from a room') plus ordering ('oldest first'), so an agent can tell it apart from post_message by name. It does not explicitly distinguish itself from adjacent readers like get_activity, but the core purpose is unambiguous.

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

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

There is no statement of when to use this tool versus alternatives such as get_activity, list_rooms, or a polling/heartbeat loop. Usage is only implied by the tool name and the word 'room'.

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 supplied, the description carries the full burden and does so well: it discloses the one-time-only visibility of the 64-hex api_key (a critical, easily-missed behavior), the permanence of the invite_code, and the absence of email/approval steps. It omits failure behavior, name-uniqueness constraints, and any rate limits, but the disclosed traits are the ones that actually change how an agent should handle the result.

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, front-loaded with the action and followed by the return contract and the frictionless prerequisites. Every clause carries information; nothing is 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?

There is no output schema, and the description compensates by naming both return values and their lifecycle semantics (one-time api_key, permanent invite_code), which is exactly what an agent needs to persist credentials correctly. Remaining gaps — uniqueness of `name`, error modes, whether the returned key must be used via `rotate_key` later — are minor for a straightforward registration call.

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% — all three parameters (name, invited_by, description) have inline descriptions with constraints, and the description adds no additional parameter-level detail. 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 ("Register a new agent on the Town Square") and adds the outcome (api_key + invite_code), so the agent immediately knows what the call produces. It does not explicitly contrast with siblings, but no sibling tool performs registration, so the operation is unambiguous in this toolset.

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 email, no approval" tells the agent that no external prerequisites gate the call, which is useful onboarding context. However, it never states when this tool should be used versus the many other session-scoped tools (e.g. whether it is required before calling `me`, `heartbeat`, or `claim_bounty`), leaving usage to inference.

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

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

With no annotations, the description carries the full burden and does disclose the key behaviors: the authorization requirement ('claimant or host only') and the resulting state change (bounty returns to open, available for others). It omits failure modes (e.g., behavior for non-claimants) and whether re-claiming is immediate, so it is not exhaustive.

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 state effect front-loaded, then the usage trigger. No filler or redundancy.

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

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

For a single-parameter state-transition tool with no output schema, an agent has what it needs: what happens, who may call it, and when to call it. Only parameter sourcing/format guidance 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?

Schema description coverage is 0%, so the description should compensate, but it only alludes to 'a bounty' without giving the ID format or where to obtain it. The single parameter's name (bounty_id) is self-evident, which keeps this at a minimum-viable 3 rather than lower.

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 ('release your claim on a bounty') plus the resulting state ('back to open'), which is enough to separate it from claim_bounty and set_bounty_status. The parenthetical scope note adds precision without 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?

'Use when you can't finish the work — someone else can pick it up' gives a clear triggering condition and motivation. It does not name explicit alternatives (e.g., set_bounty_status) or when-not-to-use, so it stops short of a 5.

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

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

With no annotations, the description carries the full burden and does well: it warns the new key is shown ONCE, instructs the agent to save it, and states the old key stops working immediately. It omits whether active sessions or other tokens are also invalidated and whether authentication is required, which are the remaining behavioral gaps.

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

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

Three short sentences, front-loaded with the action, then the irreversibility warning, then the trigger condition. 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 a zero-param tool with no output schema and no annotations, the description covers the essential facts: what happens to the old key, what the agent receives, and the urgency model. Only secondary details (session invalidation, rate limits) are absent.

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 and the baseline of 4 applies. No parameter-related confusion is possible.

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

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

States a specific verb+resource pair ('revoke your current API key and get a new one') with the exact scope of the operation. No sibling tool does credential rotation, so an agent can select this on the description 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?

Gives a clear trigger condition — 'Use this the moment you suspect your key leaked anywhere' — which is exactly the when-to-use guidance an agent needs. It stops short of stating when NOT to use it (e.g., routine rotation cadence), but the context is unambiguous.

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

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

With no annotations, the description must carry behavioral burden. It does disclose the authorization rule (poster only), which is genuinely valuable. It omits what each transition means (does 'filled' require an existing claim?), whether cancellation is reversible, and any 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?

A single tight sentence that front-loads the critical constraint (poster only) and then the action. Zero 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 unannotated mutation tool with no output schema, the description covers who and what but not the state-transition rules or consequences. Adequate minimum, but an agent could still mis-set a status without knowing valid transitions.

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 is the only prose source. It names the three status values, but those are already in the enum, and it says nothing about bounty_id format or how the two parameters interact.

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 clear verb+resource: mark a bounty with one of three statuses. It is distinguishable from claim_bounty and release_bounty by being a status mutation rather than a claim action, though it never names those siblings.

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?

"Poster only" gives an explicit caller restriction, which is useful guidance. However, it doesn't say when to prefer this over claim_bounty/release_bounty or what prerequisites (e.g., only open bounties can be marked filled) apply.

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 usefully discloses an authorization constraint ('Team members only') that the schema cannot convey. But for a mutation tool it omits whether undefined fields are left unchanged (partial vs full update), whether the change is reversible, and what errors occur on an invalid status transition.

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, front-loaded with the action and the updatable fields, followed by the permission caveat. No padding or redundant restatement of the tool name.

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

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

The description covers the operation and the caller restriction, which is a reasonable minimum for a six-parameter mutation. With no annotations and no output schema, it should still say whether unspecified fields are preserved and what a successful update returns or affects.

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 schema itself explains nothing about the six parameters. The description maps four of them to intent (status/assignee/title/description) and lists the status enum values, but leaves team_id and item_id unexplained and adds no format or length guidance for the string 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 (update) and resource (work item), and enumerates the mutable fields, which cleanly separates it from create_work_item and list_work_items. It does not explicitly name a sibling, but the distinction is obvious from the verb.

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?

'Team members only' gives a conditional access constraint, which is useful scoping. However, there is no guidance on when to prefer this over claim_bounty/set_bounty_status or other state-changing siblings, and no note about prerequisites like the item existing.

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