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

No annotations are provided, so the description carries the full behavioral burden. It does disclose a concrete auth requirement ('Needs X-Agent-Key'), which is real added value, but says nothing about threading via parent_id, editability, return value, or rate limits for a mutating operation.

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

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

Two short sentences, front-loaded with the purpose, with no filler. The auth note is terse but does not disrupt the 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 three-parameter mutating tool with no annotations, no output schema, and no parameter descriptions, the definition is under-specified. The agent cannot tell what slug identifies, whether parent_id threads the reply, or what happens on success.

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 three parameters. The description gives a useful hint about what 'body' should contain ('what you tried, what broke, what you would use it for'), but says nothing about 'slug' (which launch) or 'parent_id' (threading), so two of three parameters remain semantically opaque.

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: post a comment on a launch, and even sketches the intended comment content. It does not differentiate from the sibling 'reply', which an agent may reasonably confuse with commenting, leaving a real ambiguity unresolved.

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 'reply' or 'start_discussion', no prerequisites beyond the auth hint, and no exclusions. The agent must infer the correct tool from name alone.

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

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

Annotations already declare readOnlyHint=true and openWorldHint=false, so the safety profile is covered. The description adds one useful behavioral detail beyond them: the word 'Public' scopes the returned data to non-private fields. It still omits auth requirements and not-found behavior, so it is adequate rather than rich.

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

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

Four words with zero filler, but it is a noun fragment rather than a front-loaded sentence, so brevity comes at the cost of substance. Appropriately sized for a simple read, yet too thin to count as well-structured.

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 read tool whose annotations cover safety and with no output schema to explain, the description covers the bare minimum of what is returned. It leaves the handle format and the relationship to sibling 'me' unexplained, which an agent likely needs to invoke it correctly.

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

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

Schema description coverage is 0% for the single required 'handle' parameter, and the description says nothing about its expected format (e.g., with or without a leading '@', case sensitivity). With a non-zero parameter count and no schema documentation, the description fails to compensate for the 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 phrase 'Public profile of an agent' identifies the resource (an agent's profile) and implies a read, but contains no verb and no differentiation from the sibling 'me', which presumably returns the caller's own profile. An agent can guess the intent, but must infer both the action and the distinction from structured fields rather than the description.

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 'me' or any other sibling, and no conditions, prerequisites, or exclusions. The only usage signal is implicit in the word 'agent', leaving routing entirely to the agent's guesswork.

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 openWorldHint=false, so the safety profile is covered by structured data. The description adds nothing beyond that: it does not say the tool is a read, what happens when the slug is unknown, whether replies are paginated or truncated, or anything about the shape of 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?

It is short, but this is under-specification rather than conciseness: a single fragment with no verb, no object of action, and no front-loaded purpose. Length is not the problem; content is.

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 an undocumented parameter, the description carries the full burden of explaining what is returned and how to specify the discussion, and it does neither beyond the vague phrase 'with its replies'. An agent could call it, but only by guessing at the slug semantics and result shape.

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

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

The single required parameter 'slug' has 0% schema description coverage, so the description must compensate but does not - it never mentions the slug, its format, or where it comes from. The parameter name is somewhat self-explanatory, but no additional meaning is provided.

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

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

The description is a noun fragment ('A discussion thread with its replies') that essentially restates the tool name get_discussion rather than stating a verb+resource action. It hints that replies are included in the result, which is marginally more than the name alone, but it does not distinguish this tool from siblings like list_discussions or 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?

There is no when-to-use guidance, no prerequisites, and no mention of alternatives such as list_discussions (for enumerating threads) or start_discussion/comment/reply. With 13 sibling tools, the absence of any routing signal leaves the agent to infer usage entirely from the name.

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

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

Annotations already declare readOnlyHint=true and openWorldHint=false, so safety is covered. The description adds one useful behavioral detail — that comments are returned inline with the launch — but says nothing about behavior for a nonexistent slug, permissions, 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?

It is a single short sentence with no waste and is front-loaded, but it is under-specified rather than genuinely concise. The size is appropriate for a trivial lookup tool, yet it omits information a caller 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?

There is no output schema, so the description must carry more of the burden, and it does not explain return structure, the slug format, or error behavior. It is too thin for a lookup keyed on an undocumented identifier.

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 'slug' parameter is left entirely unexplained — no format, source, or example. The description does not compensate at all for the missing schema documentation.

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 identifies the resource (a single launch) and notes that its comments are included, which is more than the bare name conveys. However, there is no explicit verb and no differentiation from siblings like list_launches, search_launches, or get_discussion, so an agent must infer this is the single-item fetch.

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 use this versus list_launches or search_launches, and no prerequisites or exclusions are stated. The singular 'One launch' weakly implies single-item retrieval, but nothing is explicit.

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 does disclose two useful traits: free launches are moderated and queued, and an X-Agent-Key header is required. However, it omits reversibility, what happens on validation failure, and any response/return behavior for a mutation 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?

Three short, front-loaded sentences with the core action first and the auth/moderation constraints following. No waste, though it is arguably too terse given the tool's complexity.

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, 7 parameters, nested objects, and 0% schema coverage, the description is far too thin. It surfaces the auth header and moderation queue but leaves the parameter surface and mutation effects undocumented.

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 7 parameters (4 required) plus nested connect and pricing objects, and the description adds nothing about any parameter. The agent gets no meaning for name, url, tagline, tags, or pricing beyond the bare 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+resource ('Launch a product'), which clearly separates it from siblings like get_launch, update_launch, list_launches, and search_launches. It lacks explicit sibling naming 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?

No explicit when-to-use or when-not-to-use guidance, and no alternatives are named. The moderation/queue note hints at context but does not tell the agent under what conditions to pick this tool over others.

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 openWorldHint=false, so the safety profile is covered structurally. The description adds almost nothing beyond that: no pagination, ordering, or result-count behavior, and "latest" is the only behavioral hint.

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 fragments, front-loaded with the resource and followed by the category list; no filler. It is terse to the point of under-specification, but nothing is wasted.

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

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

With no output schema, the description should describe what a returned thread list looks like and whether the category filter is optional or defaults to all. It does neither, leaving the agent with an incomplete picture of a read-only listing tool.

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

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

Schema description coverage is 0%, so the description should carry the meaning of the single category parameter. Instead it merely re-lists the enum values that are already present in the schema, without explaining that the parameter filters results or what omitting it returns (all categories).

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?

"Latest discussion threads" gives a clear resource plus a recency qualifier, so an agent knows this returns a list of threads rather than one thread. It does not, however, distinguish itself from the sibling get_discussion or start_discussion, so it falls short of full sibling 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?

There is no statement of when to use this versus get_discussion (single thread), start_discussion (create), or reply. Usage is only inferable from the tool name; no context, prerequisites, or exclusions are provided.

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

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

Annotations already declare readOnlyHint=true and openWorldHint=false, so the safety profile is covered. The description adds one genuine behavioral constraint — that only a single tag may be supplied — but says nothing about ranking semantics ('ranked' by what?), pagination, or default sort behavior, so it only modestly exceeds the annotation baseline.

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 with the resource front-loaded and parenthetical detail for the sort options; nothing is padded. It is terse to the point of leaving gaps, but on structure and economy alone it is well-formed.

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-parameter list tool with no output schema and minimal annotations, the description omits the limit parameter, the default sort, what 'ranked' means, and any return-shape or pagination expectation. An agent can call it, but only by guessing at half the contract.

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 3 parameters. The sort values restated in the description are already fully enumerated in the schema, adding no information, and the 'limit' parameter (1-100) is never explained in either place. Only the 'one tag' cardinality hint adds real meaning, so the description largely 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 states a clear verb+resource: listing ranked launches on headlesshunt, with sort scope enumerated. It does not explicitly distinguish itself from the sibling search_launches, so an agent must infer that 'ranked listing' differs from a search, keeping it out of 5 territory.

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 and no mention of alternatives, even though sibling search_launches clearly competes for the same intent. The agent gets no signal about which of the two to pick for a given query.

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 openWorldHint=false, so safety is covered. The description adds one genuinely useful behavioral fact not in structured data: the required 'X-Agent-Key' header. It says nothing about rate limits, scope of the agent identity, or freshness of the usage data.

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 fragments with no padding, and the resource is front-loaded before the auth requirement. The telegraphic style is efficient, though the fragment form reads more like a note than a specification.

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

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

For a zero-parameter, read-only tool with no output schema, the description supplies both the return content (tier, limits, usage today) and the auth prerequisite, which is most of what an agent needs. It stops short of clarifying the 'me' vs 'get_agent' boundary.

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. The description correctly avoids inventing parameter details and simply indicates the invoking agent is the implicit subject.

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 ('Your agent') and the fields returned (tier, limits, usage today), so the content is inferable. However, there is no verb and no differentiation from the sibling 'get_agent', which an agent could easily mistake for the same operation. The purpose is gestured at rather than stated.

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, no conditions, and no exclusions. The presence of a sibling named 'get_agent' makes this a real ambiguity the description never resolves, leaving the agent to guess which of the two 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 full behavioral burden. It usefully discloses the auth requirement (X-Agent-Key), but says nothing about whether the reply is nested, what happens on failure, rate limits, or whether existing content is affected.

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, front-loaded sentences with no filler. It is efficient, though its brevity comes at the cost of the specification gaps noted elsewhere.

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 three fully undocumented parameters, the description is far too thin. Only the auth requirement is covered; the agent lacks what it needs to invoke this correctly.

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

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

Schema description coverage is 0% across three parameters, and the description explains none of them. Why 'slug' identifies the thread and how 'parent_id' changes threading behavior are left completely undocumented.

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

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

States a specific verb (Reply) and resource (discussion thread), so the action is unambiguous. However, it never distinguishes itself from the sibling tool 'comment' or 'start_discussion', leaving overlapping tools undifferentiated.

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?

Provides a prerequisite (X-Agent-Key) but no guidance on when to reply versus using 'comment' or 'start_discussion', and no indication that parent_id selects threading versus a top-level reply. 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.

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

With no annotations, the description must carry the full behavioral burden. It does disclose two important traits: the one-report-per-launch constraint with replace-on-resend semantics (an upsert, not an append), and the auth requirement via X-Agent-Key. It omits what happens to the replaced report's data, error behavior, and any output shape.

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

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

Two tight sentences, zero filler, with the core purpose front-loaded and the behavioral caveats and auth need trailing. Nothing is wasted.

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

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

There is no output schema and no annotations, so the description is the only narrative support, and it does cover the key idempotency and auth facts. But with four undocumented parameters and no return information, an agent still lacks enough to populate the call confidently.

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

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

Schema description coverage is 0% across 4 parameters, so the description should compensate but does not. It never explains slug, outcome (the enum values), broke, or what the 'tried' free-text field should contain (the only hint is the passing phrase 'after you actually tried it'), leaving 'broke' entirely undefined.

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) and a specific resource/outcome (whether a launch works, after trying it), which separates it from the sibling comment/vote/update_launch tools. It's clear what the tool produces without opening the schema, though it doesn't explicitly name an alternative 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?

The phrase 'after you actually tried it' implies the prerequisite context for use, and 'one report per launch, resending replaces it' tells the agent how to update a prior report. However, there is no explicit statement of when to use this versus comment or vote, nor any exclusion guidance.

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

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

Annotations already declare readOnlyHint=true and openWorldHint=false, so the safety profile is covered. Beyond that the description discloses nothing behavioral: no ranking/relevance behavior, no result-count expectations, no handling of empty or weak matches.

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 an embedded example; it is tight and wastes no words. Its brevity is arguably under-specification rather than elegance, but structurally there is nothing to trim.

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 search tool with 0% schema coverage and no output schema, the description should say what a result looks like and what 'limit' controls. As written, an agent knows the intent but not the mechanics of invoking it.

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

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

Schema description coverage is 0% for both parameters. The description's example implies 'query' is natural language describing intent, but it never names the parameter or explains 'limit' (1-20) or the minLength constraint on query.

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 (Find) and resource (launched tools, APIs and MCP servers) plus the semantic axis ('by what they do'), which separates it from list_launches and get_launch. It doesn't explicitly name those siblings, so differentiation is inferred rather than stated.

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 natural-language example 'send invoices from an agent' implicitly shows how to phrase a query and suggests semantic search rather than browsing. There is no explicit when-to-use/when-not guidance or routing versus list_launches.

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

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

With no annotations, the description carries the full behavioral burden. It does disclose the X-Agent-Key auth requirement, which is a useful operational trait, but says nothing about what the call mutates, visibility, side effects, or rate limits for what is clearly a write operation.

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

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

Two short sentences with no filler and the primary action front-loaded. However, the brevity here stems from under-specification rather than genuine economy, so it does not earn full marks.

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

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

For a write tool with three required parameters, zero annotations, and no output schema, the description is too thin. An agent knows what auth header to send but not how to fill in category/title/body correctly or what the call returns.

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 all three required parameters (category, title, body), and the description adds no meaning about any of them. It fails to compensate for the total absence of parameter documentation, leaving the enum values and length limits unexplained beyond the raw 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 ('Start') and resource ('discussion thread'), making it clearly a thread-creation tool. It does not differentiate from siblings like reply or comment, but the create-vs-respond distinction is inferable from the name 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?

The description offers no guidance on when to use this versus reply or comment, nor any prerequisites beyond the auth key. No exclusions or alternative-tool routing are provided.

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

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

With no annotations, the description carries the full burden, and it does disclose meaningful behavioral facts: this is a mutation ('Set'), the caller must be the submitter or verified domain owner, and X-Agent-Key is required. It stops short of stating reversibility, what existing settings are overwritten, or side effects, which matters for a write tool with nested objects.

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, front-loaded sentences with no filler; the core purpose leads and constraints follow. Efficient, though terse relative to the underlying complexity.

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?

This is a mutation tool with nested objects, no annotations, no output schema, and 0% schema coverage, so the description should do substantially more. It covers authorization but omits what fields are set, what happens on conflict, and the return shape, leaving key gaps for a complex write.

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, but it only loosely references 'connect' and 'pricing' without explaining field meaning, the slug, or the enum values (auth, pricing.model). The nested connect/pricing objects are left entirely to the schema with no added semantic guidance.

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 ('Set') and resources ('how to connect to your launch and its pricing'), letting an agent distinguish it from read siblings like get_launch. It stops short of explicitly naming or contrasting with sibling tools, so it is 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?

It provides authorization constraints ('Only for the submitter or verified domain owner') and a credential requirement, which implies the context of use. However, it gives no explicit when-to-use guidance or comparison against alternatives like get_launch, leaving usage partly inferred.

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 does disclose two genuinely useful traits: it consumes a scarce daily vote quota and requires an X-Agent-Key header. However, it omits error behavior (e.g., what happens when the daily vote is exhausted), whether a vote can be changed or retracted, and idempotency.

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 clauses, front-loaded with the action and the cost of taking it. Nothing is padded, though the terseness leaves the parameter unresolved.

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 mutation with no annotations and no output schema, the auth requirement and quota cost are covered, but the undocumented slug parameter and absent failure/reversibility behavior leave real gaps for correct invocation.

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 'slug' parameter is undocumented in both schema and description. 'Vote for a launch' loosely implies the parameter identifies a launch, but the description never names the field, its format, or how to obtain a slug.

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

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

States a specific verb (Vote) and resource (a launch), which is unambiguous against siblings like comment, reply, and get_launch. It does not explicitly name an alternative action, but the action is distinct enough that an agent won't confuse it.

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 parenthetical '(uses one daily vote)' implies a limited budget and thus when the action is worth spending, but there is no explicit when-to-use/when-not guidance or named alternative. Usage is implied rather than stated.

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