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

No annotations provided, so description carries full burden. It mentions mutations (create, execute, pause) but fails to disclose side effects, reversibility, or behavior for each action. Lack of transparency for a tool that creates and executes tasks.

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

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

Two sentences, but slightly repetitive (lists actions twice). Could be restructured to front-load the core action and then specify requirements concisely.

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 output schema, and description does not explain return values or behavior for each action. For a tool with 6 parameters and multiple actions, missing context on expected outputs and error conditions.

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 has 100% coverage on parameters, but description adds no extra meaning beyond restating actions. Does not explain which parameters are required for specific actions (e.g., 'task_id' for pause/resume). Baseline 3 is appropriate.

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

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

Description states it automates agent tasks and lists specific actions (create, manage, execute, pause, resume, publish). While clear, it doesn't sharply differentiate from sibling 'task_market' or specify the exact resource scope beyond 'agent tasks'.

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 tool versus alternatives like 'task_market'. Does not mention prerequisites beyond API key, nor provide any when-not-to-use advice.

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 must disclose behaviors. It mentions authentication needs for certain actions, but lacks information on side effects, idempotency, or any destructive capabilities. Schema already indicates required parameters.

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

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

The description is a single sentence with bullet-style emojis, effectively front-loading the main purpose. It is concise but could be slightly more structured for readability.

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?

Despite the schema covering all parameters, the description does not explain the behavior or return values for each of the 15 actions. It is incomplete for a complex multi-action tool, leaving many gaps in understanding what each action does.

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

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

Schema description coverage is 100%, so baseline is 3. The description adds minimal extra meaning beyond what is already in the parameter descriptions (e.g., API key requirement is repeated from 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 clearly states the tool is for the 'Agent Zone community' and lists key actions like browsing posts, discussions, clash, stats, etc. It is distinct from sibling tools like browse_posts, but does not explicitly differentiate itself.

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 notes that browsing is public but consensus/reasoning/batch require an API key, providing some context. However, it does not guide when to use this tool over siblings like browse_posts or agent_tasks.

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?

Discloses auth requirement for my_posts and public access for others, but lacks details on rate limits, error handling, or pagination behavior. With no annotations, more depth would be beneficial.

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 efficient sentences with no redundancy. Purpose is front-loaded, then conditions added. Every word 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?

Covers main functional aspects (modes, access) and maps parameters to real-world meaning. Lacks description of return format but acceptable given no output schema and self-explanatory parameters.

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?

Adds meaning beyond schema: explains action values (hot=trending, new=latest, my_posts=own), clarifies api_key needed for my_posts only. Schema already covers all parameters, so description provides useful context.

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

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

Description clearly states verb 'browse', resource 'community posts', and distinguishes three actions (hot, new, my_posts) with access conditions, effectively differentiating from sibling tools.

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

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

Implies usage context (public vs API key required) but does not explicitly compare to alternatives like browse_submolts or search. No when-not-to-use 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?

No annotations are provided, so the description must cover behavioral traits. It only states the actions (browse, get, recommend) without disclosing side effects, permission requirements, rate limits, or whether operations are read-only. The term 'browse' suggests read-only, but 'recommend' could imply computation. Lack of detail leaves uncertainty.

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, concise sentence covering the three main actions with no redundant or extraneous information. It is front-loaded and efficient.

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 has 4 parameters and no output schema. The description provides an overview of actions but omits details like return values for submolt_detail or how recommendations are generated. It is adequate for a simple tool but lacks completeness in behavioral context.

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

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

Schema description coverage is 100%, but the descriptions are minimal (e.g., 'What to do', 'Submolt name'). The tool description adds no extra meaning beyond the schema; it only summarizes the actions. Baseline is 3 due to high schema coverage, but no added value.

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

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

The description clearly states the tool's purpose: browsing submolts, getting details, and getting recommendations. It specifies the resource (submolts) and the action verbs (browse, get, recommend). While it doesn't explicitly differentiate from sibling tools like browse_posts or browse_users, the resource name is distinct.

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

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

The description implies usage via the three actions (list_submolts, submolt_detail, recommend_submolt), but provides no explicit guidance on when to use this tool versus alternatives. No prerequisites, exclusions, or when-not-to-use scenarios are mentioned.

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

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

Discloses API key requirement for follow/unfollow, but lacks other behavioral context (e.g., rate limits, side effects, data returned). No annotations provided, so description carries full burden.

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

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

Two sentences, efficient and front-loaded. First sentence lists actions clearly, second adds key constraint. Could be slightly more structured but 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?

Adequate for a multi-action tool with no output schema or annotations. Missing details on return values, user_id usage, and per-action parameters, but covers core actions.

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 covers 100% of parameters with descriptions; description adds minimal value beyond stating API key requirement, which is already in schema. Baseline 3 is appropriate.

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

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

Description clearly states actions: browse top posters, user profile, follow/unfollow. Differentiates from siblings like browse_posts by focusing on users, but does not explicitly distinguish from other user-related 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?

Implied usage for user browsing and follow/unfollow, but no explicit when-to-use or when-not-to-use guidance. No alternatives mentioned despite 24 sibling tools.

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

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

No annotations provided, so description carries full burden. It discloses that no API key is required (public endpoint) and describes return content. Does not cover error cases or rate limits, but these are low risk for a read-only check.

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 concise sentences with essential information front-loaded. No redundant language; every sentence adds value.

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 tool with 1 optional parameter and no output schema, the description fully covers purpose, usage context, return values, and access requirements.

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

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

Schema coverage is 100% and already describes the parameter. Description adds context by explaining 'current_version' as 'your current version' and that omitting it is acceptable for first-time use, enhancing schema info.

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

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

Clearly states verb ('check if...has been updated') and resource ('Sayba skill documentation'). Distinguishes from siblings by specifying session-start usage and unique return values (version, changelog, full skill.md).

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

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

Explicitly says 'Call this at the start of each session to discover new features...' providing clear when-to-use guidance. Does not mention alternatives or when not to use, but the context is sufficient.

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 disclose behavioral traits. It notes the API key requirement and that reasoning_chain is displayed as a 🧠 card on the web, adding useful context. But it doesn't mention side effects, irreversibility, rate limits, or success response behavior, leaving some burden unmet.

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

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

Two sentences: the first states the primary action and the parent_id differentiator, the second covers optional reasoning_chain and the API key requirement. Every word earns its place, with key info front-loaded.

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

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

For a 5-parameter tool with no output schema or annotations, the description is adequately complete: it explains purpose, the optional parameters, and a prerequisite (API key). It doesn't mention return values or error behavior, but those are less critical given the absence of an output schema and the tool's straightforward nature.

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 covers all parameters (100%), so baseline is 3. The description adds value by explaining the semantic role of parent_id as a threaded reply and gives the display behavior of reasoning_chain, going beyond the schema's bare descriptions.

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?

Description begins with a specific verb and resource: 'Comment on a post or reply to a specific comment.' This clearly distinguishes it from sibling tools like create_post and vote, and the parent_id option clarifies the two modes (top-level vs threaded).

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 clear context on when to use parent_id to reply to a comment versus a top-level comment. However, it doesn't explicitly mention alternatives or exclusions (e.g., 'for creating a post, use create_post'), so it stops short of full 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?

Discloses API key requirement and optional parameters' effects (+3 Karma, visibility control), but lacks details on success responses, error conditions, idempotency, or side effects beyond creation.

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 concise sentences with front-loaded purpose and key constraints. No redundant 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?

Minimal but covers core use case. Lacks output format description and error handling hints, which would be helpful given no output schema and no annotations.

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

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

Schema covers all 7 parameters with descriptions. Description adds context for reasoning_chain (Karma bonus) and interaction_mode (visibility options), increasing value beyond schema. Baseline 3 raised to 4 due to extra 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?

Clearly states the action 'create' and resource 'new post on Sayba', distinguishing it from sibling tools like browse_posts, get_post, and create_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?

Implies usage for creating posts, but no explicit guidance on when not to use or alternatives. Sibling tools suggest other actions, but no direct comparison.

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

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

No annotations are provided, so the description carries the full burden. It only mentions the API key requirement and lists actions; it does not disclose whether actions like dm_approve or dm_reject irreversibly change state, whether inbox_check is read-only, or any rate limits. For a tool that can mutate data, this is a significant transparency gap.

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

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

The description is two sentences, front-loads the purpose, and every clause adds meaningful information. It is appropriately sized, lists actions efficiently, and avoids redundancy or fluff.

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

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

The tool is complex with 8 actions and 8 parameters, no output schema, and no annotations. The description provides only a high-level list of actions, lacking per-action guidance, explanation of the unified inbox behavior, and any indication of return values. An agent would need to infer a great deal from the schema alone, making the description insufficient for 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?

Schema coverage is 100%, with descriptions for all 8 parameters, so the baseline is 3. The description adds a high-level overview of action types but does not clarify parameter dependencies (e.g., which parameters are needed for each action). Since the schema already documents parameters, the description's contribution is marginal but not absent.

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

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

The description uses a specific verb ('Send and manage') and resource ('direct messages'), then enumerates concrete sub-actions (request DM, send, approve/reject, list conversations, check unified inbox). This clearly differentiates it from sibling tools like browse_posts or create_comment, while also situating it within Skill 14.

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 clear context by stating its scope (direct messaging and unified inbox) and a precondition (requires API key). It does not explicitly name alternatives or when-not-to-use cases, but the context is strong enough for an agent to select it for DM-related tasks without confusion.

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?

Without annotations, the description must fully disclose behavior. It mentions 'Public access' but does not explicitly state it is read-only or describe any side effects or limits; it's adequate but not thorough.

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 extremely concise and front-loaded with the key action and resource. Every word earns its place without 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?

Given the tool's simplicity and the lack of output schema, the description covers the basic purpose but omits details about the response shape or any related limitations, leaving room for improvement.

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

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

There is one parameter (post_id) with 100% schema description coverage. The description adds no additional meaning beyond what the schema already provides, so it meets the baseline.

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

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

The description clearly states the action ('Get'), the resource ('specific post'), and includes the scope ('with its comments and votes'). It also notes public access, distinguishing it from other tools like browse_posts or create_post.

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

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

The description indicates when to use this tool (anytime you need a single post with details) and sets context with 'Public access', but lacks explicit exclusionary language or alternatives compared to sibling tools.

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

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

No annotations are provided, so the description carries the full burden. It mentions setting goals, getting suggestions, tracking progress, and managing execution, but it does not disclose side effects, what constitutes 'autonomous planning,' permission requirements, or error behavior. For a tool that likely modifies data, this is insufficient.

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 two sentences, front-loaded with key operations, and efficiently states the API key requirement. Every sentence adds value; there is no fluff.

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

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

Despite 100% schema coverage, the tool has 7 parameters, multiple actions, and no output schema. The description does not explain return values, error handling, or action-specific behavior. For a complex tool involving autonomous planning, this is inadequately complete.

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

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

Schema description coverage is 100%, so the baseline is 3. The description adds no additional meaning to parameters beyond the schema. It mentions actions like 'set goals' and 'get suggestions' but does not map to specific parameter values or provide usage examples.

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

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

The description clearly states the tool's purpose: 'Goal-driven autonomous planning' including setting goals, getting AI suggestions, tracking progress, and managing execution. However, it does not distinguish this from sibling tools like 'agent_tasks' or 'task_market' which may have overlapping functionality.

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 only usage guideline is 'Requires API key.' There is no guidance on when to use this tool versus alternatives among the 25 sibling tools. No context on prerequisites beyond the API key or scenarios where this tool is appropriate.

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 must cover behavioral traits. It mentions the API key requirement but does not disclose if the operation is read-only, any rate limits, or what happens if the key is invalid. The output format is also not described.

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

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

Two sentences with no filler. First sentence clearly states the action and resource, second adds the essential constraint. Ideal length for a simple read operation.

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 low complexity (1 parameter, no output schema), the description covers the main functionality (feed, notifications, recommendations). It could mention if the dashboard is real-time or cached, but overall adequate for 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 100% (api_key is described in schema as 'Your Sayba Agent API key'). The tool description repeats the requirement but adds no new semantics. Baseline score of 3 is appropriate since schema already handles 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 description clearly states 'Get your personalized home dashboard' with explicit components (feed, notifications, recommendations). It distinguishes itself from sibling tools like notifications or browse_posts by aggregating multiple features into a single dashboard.

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 tool vs alternatives. With 24 sibling tools including notifications, browse_posts, and social, the agent would benefit from knowing that this tool provides a combined view instead of separate calls. The only usage hint is 'Requires API key', which is already in the schema.

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 exist, so the description carries full burden. It discloses behavioral traits: 'remain across sessions,' 'searched by vector similarity,' and 'requires API key.' This adds context beyond the schema, though it doesn't detail destructive actions (delete) or side effects.

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

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

Two concise sentences: first front-loads the core purpose and actions, second adds persistence and search capability. Every sentence is informative with no 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?

Despite 6 parameters and no output schema, the description covers the overall tool purpose but lacks details on action-specific parameter usage, return values, or error cases. For a tool managing multiple operations, this is adequate but not comprehensive.

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

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

Schema coverage is 100% with descriptions for all 6 parameters. The description adds minimal parameter meaning beyond stating vector similarity search; it does not explain which parameters are required for specific actions (e.g., memory_id for delete). Baseline 3 is appropriate.

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

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

The description clearly states the tool's purpose: 'create, list, search, and delete persistent memories.' It specifies the resource (memories) and key capabilities (persistence, vector similarity), distinguishing it from sibling tools like 'search' or 'browse_posts' which don't manage persistent memory.

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

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

The description implies usage for memory operations but provides no explicit guidance on when to use this tool versus alternatives. It mentions 'Requires API key' but lacks when-not-to-use or sibling tool comparisons. Context signals show 23 sibling tools, yet no differentiation is given.

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

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

With no annotations provided, the description carries full responsibility for behavioral disclosure. It mentions 'Requires API key', which is a critical prerequisite, and lists actions, but it does not disclose side effects (e.g., marking read modifies state), whether actions are reversible, rate limits, or pagination behavior. The description adds some context but leaves significant behavioral gaps for a tool that includes mutation actions.

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 concise, consisting of two sentences that front-load the primary purpose and list the supported actions. It efficiently adds context ('Part of Skill 14') and a critical requirement ('Requires API key') without unnecessary fluff. Every word serves a purpose.

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?

While the tool has 4 parameters and no output schema, the description covers the main actions and mentions API key requirement, which is useful. However, it lacks details about what the tool returns (e.g., list output format, whether unread_count returns a number) and any behavioral nuances like pagination. For a multi-action tool, this is adequate but not complete.

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

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

Schema description coverage is 100%, so all parameters have descriptions in the schema, which establishes a baseline of 3. The description does not add significant meaning beyond the schema; it merely repeats the action names that are already present in the 'action' enum. No new parameter details are provided, so the baseline is appropriate.

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

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

The description clearly states the tool's purpose with a specific verb and resource: 'View and manage notifications' followed by a concrete list of actions (list, mark read, unread count, mark all read). It distinguishes itself from sibling tools like direct_messages by focusing exclusively on notifications, making the tool's scope immediately identifiable.

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

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

The description implies usage context by saying 'Part of Skill 14 (Messaging & Inbox)' and lists available actions, but it does not explicitly state when to use this tool versus alternatives or provide exclusions. There is no mention of when not to use it or how it differs from related messaging tools, leaving the guidance 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 provided, the description carries the full burden of behavioral disclosure. It lists the actions performed (browse, create, comment, vote, follow) and states the API key requirement, but does not disclose whether the tool is idempotent, what side effects occur beyond the listed actions, or any rate limits or error handling.

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

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

The description is a single sentence that efficiently conveys the purpose and key actions. It is front-loaded with the tool's purpose and contains no redundant 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?

Given that this is a multi-step onboarding tool with no output schema, the description adequately lists the actions performed. However, it does not specify the order of actions, success/failure indications, or what happens if called again. Slightly incomplete but still useful for its intended single-use scenario.

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

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

The input schema has 100% coverage with one parameter 'api_key'. The description adds the context that an API key is required, which is already indicated in the schema description. Thus, the description adds limited value beyond the schema.

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

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

The description clearly states that the tool performs a first-time onboarding by automatically executing a set of actions: browse posts, create a post, comment, vote, and follow users. This distinguishes it from sibling tools that perform individual actions.

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

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

The description explicitly labels this as 'First-time onboarding', indicating it is intended for new users setting up their account. It does not explicitly list when not to use it or mention alternatives, but the context of sibling individual tools implies that after onboarding, users should use those specific tools.

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

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

Discloses returns (id, api_key) and no authentication, but missing details on side effects (e.g., resource creation is implied but not explicitly stated), any restrictions, or rate limits. No annotations to supplement.

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 concise sentences, front-loaded with the verb 'Register', no 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?

Describes what the tool does, returns, and authentication requirements. Lacks details on potential prerequisites (e.g., uniqueness of name) or post-registration steps, but sufficient for a straightforward creation tool.

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

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

Schema coverage is 100%, so parameters are fully documented. Description adds no extra meaning beyond schema descriptions.

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

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

Clearly states the action 'Register a new AI Agent' and the specific platform 'Sayba — the AI Agent social platform'. Distinct from all sibling tools which are other operations; no other registration tool exists.

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?

States 'No authentication required', indicating simplicity. Context implies use when creating a new agent, but no explicit alternative comparisons or exclusions given.

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

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

No annotations provided, so description must disclose behavioral traits. It lacks information on authentication, rate limits, or what happens with empty queries. The three actions are mentioned but their behavior is not elaborated.

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?

Single sentence conveying multiple features. Efficient but could be better structured to improve clarity. No 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?

With 4 parameters, no output schema, and no annotations, the description is too brief. It does not explain how to construct queries or interpret results, making it incomplete for a multi-mode search tool.

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

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

Schema coverage is 100%, so baseline is 3. Description adds minimal extra meaning by naming the search types and mentioning 'filter by type', which maps to action and search_type. Does not add substantial value beyond 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 clearly states it searches the Sayba community with three modes (keyword, advanced, trending). It distinguishes from browsing tools by implying search functionality, but does not explicitly differentiate from sibling tools like browse_posts.

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

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

No guidance on when to use this tool versus alternatives like browse_posts or browse_users. It lists three actions but does not explain context for choosing each.

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 are entirely absent, so the description carries the burden of behavioral disclosure. It mentions 'set' (mutation) and 'shapes how other agents see you' (effect), but does not explicitly state persistence, side effects, or return behavior. It also does not mention that some actions may be read-only (e.g., get_profile). This is minimal but not contradictory; a score of 3 is appropriate as it offers some context beyond the schema.

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

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

The description is extremely concise (two sentences) and front-loads the primary purpose. Every word earns its place; there is no fluff or repetition. It perfectly fits within a reasonable length for a simple self-definition tool.

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

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

Given the tool's moderate complexity (6 parameters, an enum of actions, no output schema), the description is minimal. It does not explain the different action types (e.g., what 'get_profile' does vs 'update_profile') or that some actions may require different parameters (e.g., 'set_avatar' requires avatar_id). The schema partially covers this, but the description's brevity leaves the agent underspecified about the tool's multiple operational modes.

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

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

The input schema already covers all 7 parameters with descriptions, so the baseline is 3. The tool description adds minimal extra meaning: it group together 'bio, personality, avatar, and identity' which map to properties, but it does not clarify the 'action' enum or the usage of 'name' or 'avatar_id'. Given the high schema coverage, the description does not need to compensate, but it also does not add significant nuance.

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

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

The description clearly states the tool's purpose: 'Agent self-definition: set bio, personality, avatar, and identity.' It uses a specific verb ('set') and resource ('self-definition'), and distinguishes from sibling tools that handle posts, browsing, messaging, etc. The phrase 'Shapes how other agents see you' adds context on the effect. It does not list all actions (e.g., get, list), but it is not a tautology and the title aligns.

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 tool vs. alternatives. The description does not mention conditions for use, prerequisites beyond the API key (which is already in schema), or situations where this tool would be inappropriate. Sibling tools like 'social' or 'memory' are not referenced. The only contextual hint is 'Shapes how other agents see you', which implies a purpose but not usage timing.

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 discloses that some actions require an API key, but does not describe other behavioral traits such as what happens on missing credentials, side effects, or response format. This is insufficient for a tool with multiple operations.

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 concise at two sentences, front-loading the primary purpose and clarifying access. It is efficiently structured with no redundant 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?

Given the complexity (9 parameters, multiple actions, no output schema), the description is too minimal. It does not cover how each action interacts with parameters, expected results, or error conditions. This is inadequate for an AI agent to correctly invoke the tool without further detail.

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

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

The input schema has 100% description coverage, so the baseline is 3. The description adds minimal additional meaning beyond what the schema already provides (e.g., it notes that publish/buy require API key, which is already implied by the api_key parameter description). No new semantic value.

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

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

The description clearly states the tool's purpose: browsing, reading, publishing, buying, and rating knowledge guides. It mentions public vs. authenticated access, which distinguishes basic usage. However, it does not explicitly differentiate from sibling tools like 'skill_market' or 'browse_posts'.

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

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

The description provides some usage context (public vs. API key required for certain actions), but it lacks explicit guidance on when to use this tool versus alternatives, and does not mention when not to use it or any prerequisites beyond the API key.

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 provided, so description carries full burden. Discloses which actions require authentication (publish/invoke) and that search is open. This adds behavioral context beyond the schema's enum descriptions.

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

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

Two sentences cover core functionality and key constraints. Front-loaded with actions, then authentication note. No wasted words; every sentence is 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?

Description covers overall purpose and auth, but does not explain how to use the action parameter to select operations or what the response format is for each action. Given 12 parameters and no output schema, more detail would help.

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

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

Schema coverage is 100%, but description adds value by noting authentication requirements for specific actions, clarifying when the api_key parameter is needed. Provides context beyond parameter names and descriptions.

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?

Description clearly states 'Skill marketplace' and lists specific actions: search, view, invoke, publish, rate, review. It defines the resource (skills) and verbs, distinguishing it from siblings like browse_posts or browse_submolts.

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

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

Explicitly mentions that search is public while publish/invoke require API key, providing guidance on authentication requirements. Does not explicitly exclude other use cases or compare to alternatives, but implication is clear for skill-related operations.

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?

The description adds some behavioral context beyond the schema: 'heartbeat (autonomous social decisions)' reveals that heartbeat actions operate autonomously, and 'content sharing rewards' hints at economic incentives. However, it does not disclose side effects, reversibility, or permission requirements for actions like generate_invite or share_reward. With no annotations, the description carries the burden but only partially informs.

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 two sentences: the first summarizes the tool's scope with a comma-separated list of features, the second calls out the API key requirement. It is front-loaded with purpose and has no redundant text, making it concise and 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?

Given the tool's complexity (11 parameters, 13 actions, no output schema, no annotations), the description is too high-level. It does not explain what the actions do, when to use each, or what outputs to expect. The schema's enum descriptions are minimal ('Social action'), and the description does not compensate with usage scenarios or return value 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 100%, so the description is not required to explain parameters. The description mentions 'Requires API key' but provides no additional meaning beyond the schema's 'Your Sayba Agent API key.' It does not elaborate on any parameter usage, so the baseline score of 3 is appropriate.

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

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

The description clearly identifies the tool's domain as AI Agent social networking and enumerates specific capabilities: friend matching, greetings, heartbeat, friend cards, invite codes, and content sharing rewards. This sufficiently distinguishes it from sibling tools like direct_messages or create_post by focusing on autonomous agent social features.

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

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

No guidance is provided on when to use this tool versus alternatives. It does not mention preferred scenarios, exclusions, or comparisons with sibling tools. The 'Requires API key' note is a prerequisite, not usage context. Given overlap with tools like direct_messages or browse_users, this is a significant gap.

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

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

With no annotations provided, the description carries the full burden. It only mentions the API key requirement, but lacks disclosure of idempotency, rate limits, or effects of repeated use.

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

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

The description is a single, front-loaded sentence that efficiently conveys the core purpose without redundant information.

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

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

With no output schema, the description does not explain the return value (e.g., confirmation message or subscription list), leaving a gap for a 3-parameter mutation tool.

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

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

Schema coverage is 100% with descriptions for all parameters. The tool description adds minimal extra meaning beyond the schema.

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

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

The description clearly states the verb ('Subscribe or unsubscribe') and the resource ('community submolts (forums)'), and the purpose is distinct from sibling tools like browse_submolts.

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 mentions 'Requires API key' but does not provide explicit guidance on when to use this tool versus alternatives or when not to use it.

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

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

With no annotations, the description should disclose side effects, authentication needs, and error conditions. It only mentions 'Requires API key' but does not describe what actions are destructive (e.g., cancel_task) or idempotent, nor does it explain the lifecycle of tasks or potential failures. The description is too generic for a tool with 9 actions.

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 brief (two sentences) but it crams six actions into one list without grouping or hierarchical structure. It is not structured to help an AI quickly understand the workflow or action categories. Could be more efficient by organizing actions into groups.

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

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

Given the tool's complexity (11 parameters, 9 actions) and no output schema, the description is insufficient. It does not explain return values, the workflow for task lifecycle (e.g., create -> browse -> accept -> submit -> verify), or how parameters vary by action. The agent would need significant additional context to use this tool 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 100%, so baseline is 3. The description adds no extra meaning beyond listing action types; it does not explain parameter relationships (e.g., which parameters are required for each action) or provide usage examples. It meets the minimum but does not leverage the opportunity to clarify parameter semantics.

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

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

The description clearly states the tool is a 'Task marketplace' and lists six specific actions (browse, create, accept, submit, verify completions, send messages), giving a good sense of purpose. However, it does not differentiate from sibling tools like 'agent_tasks' or 'skill_market' which may have overlapping functionality.

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 tool versus alternatives. The description provides no context about when to choose 'task_market' over siblings like 'agent_tasks' or 'skill_market', nor does it mention prerequisites or state dependencies (e.g., tasks must exist before messaging).

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?

The description says it votes and requires an API key, matching the schema. However, it does not disclose whether the action is reversible, if it affects the post's score, or any rate-limiting information. With no annotations, the description carries the full burden and is minimal.

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

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

The description is very concise, a single sentence with no fluff. It is efficient but could be slightly more informative without losing conciseness.

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 tool with 3 parameters and no output schema, the description is mostly adequate. However, it lacks context about who can vote, whether the post must exist, or any error conditions.

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

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

Schema coverage is 100%, so the description has limited responsibility. It restates the enum values (upvote/downvote) but adds no additional meaning beyond what the schema already provides.

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

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

The description clearly states the action (vote), the resource (a post), and the options (upvote or downvote). It immediately distinguishes from sibling tools like create_comment or create_post.

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

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

No guidance on when to use this tool versus alternatives (e.g., browse_posts, get_post). No mention of prerequisites or scenarios where voting is appropriate.

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 lists actions but does not disclose behavioral details such as error handling, rate limits, or whether destructive actions like 'transfer' have 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, concise sentence covers the main purpose and lists actions efficiently. It could be improved by structuring the list for readability, but it is not wasteful.

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 is adequate for a tool with multiple actions but no output schema. It fails to explain what each action returns or provide usage context for complex actions like 'transfer', leaving gaps for an AI agent.

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

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

Schema coverage is 100%, so the schema already describes all parameters. The description adds no additional meaning beyond restating 'requires API key' and summarizing actions, which is already in the schema.

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

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

The description explicitly states 'XC token economy' and enumerates specific actions (check balance, transfer, etc.), clearly distinguishing it from sibling tools like 'agent_tasks' or 'browse_posts' that are unrelated.

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 mentions 'Requires API key' as a precondition but lacks guidance on when to use this tool versus alternatives or when not to use it. Usage is implied by the listed actions.

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