VibeSharing MCP Server

Server Quality Checklist

Profile completionA complete profile improves this server's visibility in search results.

Latest release: v0.9.3
Disambiguation4/5
Most tools have clearly distinct purposes (e.g., list vs. create vs. deploy vs. share), but the deploy/share family (deploy_prototype, deploy_files, share_html, import_repo) could be misselected without careful description reading. The descriptions are detailed enough to disambiguate, but the overlapping actions of deploying and registering create minor ambiguity.
Naming Consistency5/5
All tool names follow a consistent verb_noun snake_case pattern (e.g., list_prototypes, create_collection, send_support_request). Even multi-word names like close_feedback_loop and generate_feedback_topics maintain the convention. No camelCase or mixed styles detected.
Tool Count3/5
With 21 tools, the server is at the 'heavy' end of the borderline range. While each tool appears to serve a distinct purpose, the count feels substantial for a typical MCP server, and an agent may need to scan many options before choosing.
Completeness3/5
The server covers a wide range of operations: authentication, deployment, sharing, feedback triage, context management, and diagnostics. However, there are notable gaps: no update or delete operations for prototypes or collections, and no get-by-ID function for prototypes. These limitations could force agents to work around them.
Average 4.1/5 across 21 of 21 tools scored. Lowest: 3.3/5.

How is the quality score calculated?

The overall quality score combines two components: Tool Definition Quality (70%) and Server Coherence (30%).

Tool Definition Quality measures how well each tool describes itself to AI agents. Every tool is scored 1–5 across six dimensions: Purpose Clarity (25%), Usage Guidelines (20%), Behavioral Transparency (20%), Parameter Semantics (15%), Conciseness & Structure (10%), and Contextual Completeness (10%). The server-level definition quality score is calculated as 60% mean TDQS + 40% minimum TDQS, so a single poorly described tool pulls the score down.

Server Coherence evaluates how well the tools work together as a set, scoring four dimensions equally: Disambiguation (can agents tell tools apart?), Naming Consistency, Tool Count Appropriateness, and Completeness (are there gaps in the tool surface?).

Tiers are derived from the overall score: A (≥3.5), B (≥3.0), C (≥2.0), D (≥1.0), F (<1.0). B and above is considered passing.

Tool Scores

Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description should clarify whether removal is permanent, reversible, or requires specific permissions. It does none of that. It also introduces ambiguity by saying 'reference link or note' without explaining if these are distinct entities or if both are affected.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single sentence that states the essential operation without any redundant or filler content. It is concise and front-loaded.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple single-parameter tool, the core purpose and parameter are clear. However, the lack of usage guidance and behavioral transparency (e.g., permanence, error cases) leaves the description only moderately complete for an agent to invoke correctly in all situations.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema is fully self-documenting with 100% coverage for the single parameter 'link_id'. The description adds minimal extra meaning beyond confirming the ID is used for removal, so it does not warrant a higher score.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the action ('Remove'), the target resource ('reference link or note'), and the method ('by its ID'). This distinguishes it from sibling tools like add_context_link or list_context_links, which perform different operations.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
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, nor are any prerequisites, exclusions, or typical scenarios mentioned. The description only states the operation, leaving the agent without context to decide when to invoke it.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations exist, so description is the sole source of behavioral info. 'Sync' implies mutation/overwrite but the description doesn't disclose whether it replaces, merges, or how it handles existing context. It also doesn't mention permissions, errors, or return values.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two concise sentences, front-loaded with the purpose. No fluff; the benefit statement is useful.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The tool has no annotations or output schema, so the description must explain behavior, effects, and return values. It only gives a high-level purpose, leaving ambiguity about sync semantics (overwrite vs merge), error handling, and relationship to sibling tools like add_context_link.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema covers both parameters completely with descriptions, so baseline is 3. The description does not add any parameter-specific semantics beyond what the schema provides.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool syncs project context (CLAUDE.md, AGENTS.md) to VibeSharing, using a specific verb and resource. However, it doesn't explicitly differentiate from sibling tools like add_context_link, so it's clear but lacks sibling distinction.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides context ('maintain context across AI sessions and team members') implying when to use it, but doesn't offer alternatives or exclusions. No guidance on when to use this over add_context_link or other tools.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden of behavioral disclosure, but it only states the action and a safety precondition. It does not disclose side effects like overwriting existing prototypes, irreversibility, permission requirements, or return behavior. The warning about user confirmation is a guideline, not a transparency disclosure.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is brief and front-loads the primary action, followed by a crucial usage warning. Every sentence adds value; there is no redundancy or filler.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The tool performs a significant action (deploy + register) with no output schema or annotations, yet the description doesn't explain what happens after successful deployment (e.g., returned URLs, IDs, or how to verify success). It also omits clarification on the update-vs-create behavior for prototype_id, though the schema covers that parameter. The prerequisite guidance is helpful, but the overall context is incomplete for an agent to know how to proceed after invocation.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, and the description adds no additional parameter semantics beyond referencing 'code' generically. The schema already documents each parameter well, so this meets the baseline but doesn't exceed it.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool's function with a specific verb ('Deploy') and resource ('code directly to VibeSharing' and 'to Vercel'), and explicitly mentions the combined action of deploying and registering as a prototype. This distinguishes it from sibling tools like register_prototype and deploy_files.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides explicit usage guidance by requiring resolve_target to be called first and mandating user confirmation before deployment. It gives clear context for when to use the tool, but does not mention alternatives or when-not-to-use scenarios, so it falls short of a 5.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
There are no annotations, so the description carries the full burden. It discloses the action ('Attach') but gives no information on side effects, permissions, or what happens when both folder_id and project_id are provided. The lack of any behavioral detail beyond the core action is a significant gap.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences, front-loaded with the primary action and target, then a succinct list of use cases. Every sentence contributes value and there is no fluff or repetition.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The description covers what the tool does and gives usage context, but for a mutation tool with no annotations or output schema, it omits critical details like expected behavior if both target IDs are provided, error handling, or return value. It's adequate but leaves noticeable gaps.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so the schema already documents all five parameters. The description adds examples of accepted URLs (Figma, Confluence, Google Docs) and clarifies the free-text note use case, but it doesn't elaborate on the folder_id/project_id relationship beyond the schema's 'Provide either' instruction. Baseline 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description uses the specific verb 'Attach' and identifies the resource as 'a reference link or note' targeted at 'a collection or project/prototype.' It also lists concrete examples (Figma designs, PRDs, Confluence docs) that distinguish it from sibling tools like remove_context_link and list_context_links.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides clear use-case guidance ('Use this to add links to Figma designs, PRDs, Confluence docs, or free-text notes') which tells the agent when to invoke it. It doesn't explicitly name alternatives or when not to use it, but the context is unambiguous compared to siblings like sync_context.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
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 only states 'get' which implies no mutation, but does not explicitly confirm read-only behavior, access restrictions, or if any state changes occur. There is no mention of what is returned (e.g., fields, ordering, pagination) or any side effects. This lack of detail is a significant gap for a tool with no structured annotation safety hints.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, well-structured sentence that front-loads the main purpose and then lists all filter options. Every clause carries useful information without redundancy. It is appropriately concise and easy to scan.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
While the tool is relatively simple, the lack of an output schema and annotations means the description should explain more about the response shape or any limitations. It covers the main filtering options but does not mention what the returned data looks like, whether comments are included, or how to interpret the results. For a basic get, this is adequate but leaves clear gaps in an agent's understanding.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema already provides 100% description coverage for all four parameters, so the baseline is 3. The description nicely lists the allowed enum values for status and priority, reinforcing what the schema states, but does not add deeper meaning (e.g., 'unassigned' semantics in assigned_to, or how filters combine). No new information beyond the schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states a specific verb ('Get') and resource ('feedback and comments for a specific prototype'), making the tool's purpose unambiguous. It also distinguishes itself from sibling tools like 'triage_feedback' and 'close_feedback_loop' by focusing on retrieval, not processing or mutation.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides clear context: it is for fetching feedback on a specific prototype with optional filters by status, priority, or assignee. It does not explicitly mention when not to use it or offer alternatives, but the sibling tools (e.g., 'triage_feedback') are obviously different in purpose, so 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.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden of behavioral disclosure, but it does not mention any side effects, permissions, or expected outcomes. It only states the action and conditions, leaving the user uninformed about what happens after sending (e.g., confirmation, asynchronous processing, rate limits).
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is two sentences, with the first sentence stating the primary purpose and the second providing usage context. Every word is necessary, and the structure is front-loaded and highly concise.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The description is adequate for a simple tool with a complete schema, but it does not explain what happens after sending a support request or what the user should expect as a response. Since there is no output schema, this missing information leaves a minor gap in completeness.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema covers 100% of parameters with descriptions, so the baseline is 3. The tool description does not add any additional parameter semantics, but it does not need to since the schema is complete.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the action ('Send a support request') and the target ('to the VibeSharing admin'), which distinguishes it from the sibling tools. The verb 'send' and resource are specific, making the tool's purpose unambiguous.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides explicit conditions for use: 'when the user has an issue you can't resolve, needs a configuration change, or wants to report a bug.' It does not mention when not to use it or alternative tools, but the 'Use this when...' phrasing gives clear context.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations are absent, so the description must disclose behavior. It only states the basic update operation and bulk capability; it does not mention permissions, reversibility, side effects like stakeholder notifications, or return values. This is a significant gap 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.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences, front-loaded with the action, no redundant text. The usage sentence adds context without bloat.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
With no output schema and no annotations, the description leaves out return behavior and side-effect expectations. However, the schema fully documents parameters, and the tool's purpose is clear. Adequate but with gaps for a mutation tool.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema covers all parameters with descriptions and enums. The tool description merely restates three field names without adding usage details. Baseline 3 applies.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
States 'Update status, priority, or assignee on one or more feedback items'—specific action, resource, and fields, distinguishing it from read or analysis tools like get_feedback and generate_feedback_topics.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
Explicitly says 'Use this to triage feedback from within your editor,' giving a clear use case. Does not mention alternatives or when not to use, but the 'Use this' instruction provides enough context for selection.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must carry the full burden. 'List' clearly indicates a read-only operation, but the description does not disclose return format, pagination, or behavior when both IDs are provided. It is minimally transparent but not misleading.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, clear sentence with no superfluous words. It front-loads the action ('List') and the object ('all reference links and notes'), making it immediately understandable.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple read-only list tool with two well-documented parameters, the description is mostly complete. However, it does not explicitly mention that exactly one of folder_id or project_id must be provided, though the schema covers this. No output schema exists, but the return value is adequately implied by 'list'.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, with each parameter already fully described ('Collection (folder) ID' and 'Project or prototype ID'). The description restates the target types but adds no new parameter-level semantics, warranting the baseline 3 for high schema coverage.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly identifies the action ('List') and the resource ('reference links and notes') with scope ('collection or project/prototype'). This distinguishes it from sibling tools like add_context_link and remove_context_link, which perform different operations.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies usage when you need to view context links for a collection or project, but it does not explicitly state when to use this tool over alternatives or mention exclusions. The schema provides the either/or requirement for IDs, but the description itself lacks explicit guidance.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the burden. It discloses the creation side effect and adds conceptual context (collections group related projects/prototypes). However, it omits details about permissions, duplicate name handling, or return values. This is minimal viable transparency for a simple create operation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Three concise sentences with front-loaded action: first sentence states what it does, second gives background, third gives usage. No filler or redundancy.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's simplicity (2 params, no output schema), the description provides purpose, background, and a usage scenario. It doesn't explicitly mention the return value after creation, but for a basic create tool this is not a major gap. It is reasonably complete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema provides descriptions for both parameters (100% coverage). The tool description adds no extra parameter semantics beyond what the schema already states, so the baseline of 3 applies.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the action ('Create a new collection') and the resource ('in your VibeSharing organization'), and distinguishes itself from siblings like list_collections by emphasizing creation and grouping of related projects/prototypes.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
It gives explicit usage context: 'Use this before deploying a prototype if you need a new collection to put it in.' This tells the agent when to invoke it, though it doesn't mention alternatives or exclusions like checking existence via list_collections.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden. It discloses the read-only action ('List'), the returned fields, and the fuzzy-match behavior of the filter. However, it lacks explicit statements about side effects, permissions, or edge cases like empty results.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences, front-loaded with the main action, no redundant information. Every word contributes to understanding the tool's purpose and capabilities.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The tool is simple with one optional parameter and no output schema. The description explains the primary function, the displayed fields, and the filter behavior, making it fully complete for its complexity.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The sole parameter 'search' is fully described in the schema with an example, so the schema already provides high coverage. The description adds 'fuzzy matched' which is also in the schema, offering no additional semantics beyond the structured definition.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly identifies the action (list), the resource (prototypes), and the organizational scope, distinguishing it from sibling tools like list_collections and list_context_links. It also specifies the displayed fields, enhancing clarity.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description states the primary use case (listing all prototypes in the organization) and an optional filter, giving clear context. It does not explicitly mention alternatives, but the resource-specific naming makes the intended usage obvious.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden of behavioral disclosure. It discloses that the tool mutates state by 'Pulling the code into a VibeSharing-hosted repo and deploys it to Vercel,' and it highlights a critical safety requirement (user confirmation). It does not mention permissions or failure modes, but the provided context—especially the importance warning—is substantial for an import/deploy tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two well-structured sentences plus a bolded IMPORTANT admonition. Every sentence contributes: the first defines the action, the second elaborates on the process, and the third provides critical usage safety. There is no fluff, and the most important instruction is visually emphasized. This is an exemplary concise description.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given 7 parameters, 100% schema coverage, and no output schema, the description adequately covers the tool's flow and key precondition. It tells the agent to use resolve_target first and warns against unconfirmed imports. It doesn't detail what happens after execution (e.g., response format), but with no output schema the description is not required to. The main gap is lack of mention of potential side effects on existing prototypes, but schema covers parameter semantics.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so each parameter already has descriptive meaning in the schema. The tool description adds minimal new parameter-level information beyond restating default behaviors (e.g., 'Defaults to the repo name' is already in the schema). Thus it meets the baseline but does not slightly exceed it by clarifying relationships between parameters like 'deploy_name' and 'name'.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool imports an existing GitHub repo into VibeSharing, pulls code, and deploys to Vercel. The verb 'import' and specific resource 'GitHub repo' make the primary purpose obvious. It doesn't explicitly differentiate from siblings like upload_source or deploy_prototype, but the combined import+deploy behavior is distinct enough for an agent to recognize its role.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines5/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides explicit when-to-use guidance: 'Before calling this, use resolve_target to confirm the collection, project name, and deploy name with the user.' It also states a clear precondition: 'Do not import without user confirmation on where it should go and what it should be called.' This tells the agent exactly when and under what conditions to invoke the tool, going beyond vague hints.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the transparency burden. It implies a safe read-only operation ('List all collections') and adds the fuzzy matching behavior for the optional search parameter. It does not mention pagination or rate limits, but that is acceptable for a simple listing tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two concise sentences front-load the primary purpose and then provide usage context and filtering behavior. Every phrase earns its place with no irrelevant information.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple tool with one optional parameter and no output schema, the description adequately covers what it does, when to use it, and how filtering works. It implies the return includes collection IDs, which is sufficient for the stated use case.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, and the schema already describes the 'search' parameter with examples. The tool description adds little beyond a restatement of the fuzzy matching detail, so it meets the baseline but does not exceed it.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool lists all collections (folders) in the organization, using the specific verb 'List' and a concrete resource. It also distinguishes itself from siblings like create_collection and list_prototypes by noting its role in finding collection_id for prototype registration.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
It provides explicit context for when to use the tool: 'Use this to find the collection_id when registering prototypes.' It lacks explicit exclusions or mention of alternatives, but this clear use case is enough to guide an agent.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
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 clearly explains that the tool fuzzy-matches names, suggests placement, checks deploy_name availability, and returns structured options for user confirmation. This implies a read-only, pre-flight role and helps the agent avoid using it as a deploy/register action.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Three sentences, all front-loaded with the most critical instruction ('CALL THIS BEFORE...'). Every sentence adds value: when to use, what it does, and what it returns. No fluff or repetition.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The tool has three optional parameters, no output schema, and no annotations. The description covers purpose, usage, key behaviors, and the nature of the return value ('structured options'). It lacks explicit detail about return fields or edge cases, but the description is sufficient for the tool's straightforward pre-deployment resolution role.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema descriptions already cover all three parameters at 100% coverage, including notes that project_name and collection_name are fuzzy matched and that deploy_name is checked for availability. The description adds little parameter-level meaning beyond what the schema provides, so the baseline of 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description opens with an explicit directive: 'CALL THIS BEFORE deploying or registering a prototype when the user hasn't provided exact IDs.' It clearly identifies the tool's role as a pre-deployment resolver that fuzzy-matches names, checks availability, and returns options. This distinguishes it from siblings like deploy_prototype and register_prototype.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description explicitly states when to use the tool ('when the user hasn't provided exact IDs' and 'BEFORE deploying or registering'), giving clear context. It does not explicitly name alternatives or state when not to use the tool, but the 'before' phrasing implies the downstream deployment/registration tools are the alternatives.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must carry the transparency burden. It discloses that uploaded source becomes downloadable by colleagues and that the tool does not deploy. However, it does not mention whether the upload replaces existing source, required permissions, or other side effects like storage limits. This is a moderate disclosure gap.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is two concise sentences, front-loading the core action and then providing context. No word is wasted, and it reads clearly for an AI agent.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple upload tool with no output schema and no annotations, the description supplies the key outcome (downloadable source) and the use case (sharing without deployment). It lacks details on failure handling or overwrite behavior but remains largely complete for a tool of this complexity.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema covers 100% of parameters with descriptions, so the baseline is 3. The description's mention of 'source code' and 'without deploying it' adds minimal parameter-level meaning beyond what the schema already provides. It does not explain storage option nuances or default behavior beyond schema descriptions.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the verb ('Upload') and the resource ('source code for an existing prototype on VibeSharing'). It also distinguishes this tool from deployment-focused siblings by explicitly saying 'without deploying it', making its purpose unambiguous.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines5/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description gives explicit usage guidance: 'Use this when you want to share code without deploying it.' This directly instructs when to invoke the tool and implies that deployment tools should be used for deploying. It provides a clear context for selection.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
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 states the tool checks connectivity and authentication, but does not disclose what happens on invalid token (e.g., error, return value) or whether it makes network calls. This is adequate but not rich.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is two sentences, front-loaded with the action and resource, and every word adds value. No filler or repetition.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple, zero-parameter tool with no output schema, the description is complete: it explains what it does, when to use it, and implies it is a pre-flight check. It could mention the result format, but that is not critical for an agent to invoke it.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema is empty (0 parameters), and schema description coverage is 100%. The baseline for 0 params is 4, and the description adds no parameter-specific details because none exist. It appropriately keeps the description focused on the tool's behavior.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states a specific verb ('Verify') and resource ('VibeSharing deploy token'), making the tool's purpose unambiguous. It is distinct from all sibling tools, which focus on deployment, listing, or context operations.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description explicitly says 'Use this to check connectivity and authentication before other operations,' providing clear when-to-use guidance. It does not explicitly list alternatives or exclusions, but for a token verification tool with no parameters, this is sufficient.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the burden of disclosing side effects. It explicitly mentions the auto-clearing of stuck deploy locks, a non-obvious mutating behavior, which is important for an ostensibly diagnostic tool. It does not mention other potential side effects, but the main behavioral trait is covered.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is two sentences, front-loaded with the core purpose, followed by specific checks and a clear usage directive. Every sentence adds value with no fluff or repetition.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool has no parameters, no annotations, and no output schema, the description covers its actions and side effects well. It lacks an explicit mention of the return format (e.g., a health report), but for a 0-parameter diagnostic tool, it is sufficiently complete for an agent to select and invoke it.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The tool has zero parameters and the schema is empty, so there is no parameter information to add. The baseline for 0 params is 4, and the description provides no parameter-related details because none are needed.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states a specific verb ('Run a comprehensive health check') on a specific resource ('VibeSharing setup') and enumerates the exact checks performed. This distinguishes it from sibling tools like verify_token or resolve_target that handle individual concerns.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides a clear use case ('Use this to troubleshoot issues') and implies it is a broad diagnostic tool while siblings are more focused. It lacks explicit exclusions or alternative guidance, but the context is clear.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
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 discloses the core behavior: uploads HTML and returns a shareable link with a feedback widget. It also mentions the parameter size limitation. However, it does not discuss reversibility, side effects, or any access requirements, leaving some behavioral aspects unspecified.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is three sentences, front-loaded with purpose. Each sentence contributes meaningfully: what it does, when to use it, and how to handle large files. No filler or redundancy.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Despite having no output schema and no annotations, the description covers the tool's purpose, usage context, and parameter choice guidance. It mentions the shareable link as the output. It could mention more about update/create behavior with prototype_id, but the schema covers that, and the tool is relatively simple.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, so the baseline is 3. The description adds value by explaining the rationale for choosing file_path over html due to size limits, which is not present in the schema. This extra context helps the agent select the correct parameter.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the verb and resource: 'Share a static HTML page on VibeSharing.' It distinguishes the tool from heavier alternatives like Vercel, GitHub, and React wrappers, and from sibling tools by emphasizing the simplest, no-build-step sharing method.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines5/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
It explicitly states when to use: 'for standalone HTML files, one-page prototypes, or any static content that doesn't need a build step.' It also provides an explicit alternative for large files: 'use file_path instead of html to avoid MCP parameter size limits.'
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the behavioral disclosure burden. It discloses side effects (pushes to GitHub, deploys to Vercel), a precondition (requires existing prototype ID), and a resource constraint (parameter size limits). It does not mention what happens on redeploy or failure, but the disclosed traits are significant and not otherwise visible.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is concise yet information-dense. The core statement is front-loaded, followed by a practical file-size tip and a critical safety check. The IMPORTANT section is warranted and clearly delimits a do-not-proceed condition. No filler words or redundant restatements of the schema.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's complexity (5 parameters, no annotations, no output schema), the description covers purpose, prerequisites, parameter selection tips, and user-confirmation requirements. It does not differentiate from the closely named sibling deploy_prototype, nor describe return values, but the coverage is strong for an agent to invoke the tool correctly.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema covers 100% of parameters, so baseline is 3. The description adds semantic value by explaining why file_paths should be chosen over files for large payloads, connecting to the ~100KB MCP limit. This goes beyond the schema's static descriptions and helps the agent make correct parameter choices.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description opens with a specific verb and resource: 'Deploy a multi-file Next.js project to VibeSharing.' It further clarifies the workflow ('Pushes files to GitHub, deploys to Vercel'), making it distinct from sibling tools like deploy_prototype or upload_source. The scope is clear and unambiguous.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines5/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
Provides explicit usage guidance: 'For large files, use file_paths instead of files to read from disk and avoid MCP parameter size limits (~100KB).' It also gives a strong prerequisite and in/out condition: 'Before calling this, use resolve_target to confirm the target prototype with the user. If the user hasn't specified where to deploy, do NOT proceed — ask first.' This is actionable and prevents misuse.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior5/5
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 thoroughly explains the tool's behavior: it pulls open feedback, matches changes, resolves items with explanations, and notifies stakeholders via email with an exact summary. It also reveals the stakeholder-facing outcome ('The stakeholder sees exactly what happened to their feedback'). This goes well beyond a simple action verb and covers side effects, making it highly transparent.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is appropriately sized for the tool's complexity. It uses a bold imperative for when to call, a concise flow list, and a stakeholder impact statement. Every sentence earns its place—no fluff or redundancy. The numbered flow improves scannability without wasting words.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool has 3 parameters, no output schema, and no annotations, the description is remarkably complete. It covers the full workflow, the input expectations (open feedback, resolutions), the side effect (stakeholder notification), and even provides format examples. There is no obvious missing context that would prevent an agent from selecting and invoking this tool correctly.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema already covers all parameters (100% coverage), but the description adds meaningful context: it explains that deploy_url is included in the notification, and it gives specific guidance on writing the note for resolutions ('Be specific: 'Nav restructured to separate admin and user flows' not 'Fixed the navigation''). This enriches the meaning of the resolutions parameter beyond the schema description, justifying a score above the baseline.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description opens with a specific verb+resource: 'CALL THIS AFTER DEPLOYING when there is open feedback. Matches what you just built to open feedback items, resolves them with explanations, and notifies the original stakeholders.' This clearly distinguishes it from siblings like get_feedback (pulling feedback) and triage_feedback (likely categorizing items), establishing a unique purpose.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description gives explicit context: 'CALL THIS AFTER DEPLOYING when there is open feedback' and outlines a step-by-step flow starting with pulling feedback via get_feedback. It does not explicitly state when-not-to-use or name alternative tools, but the condition 'when there is open feedback' and the flow provide clear usage guidance. A score of 4 reflects the clear context without full exclusion guidance.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior5/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries full responsibility for behavioral disclosure. It explicitly states the interactive prerequisite (ask user for focus), the conditional behavior (skip generation for 'awareness'), and the generation rule (3-5 questions weighted toward focus). This goes beyond a simple mutation statement.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is well-structured: a one-sentence summary, an 'IMPORTANT' call-out, a numbered list of focus options, and a concise conditional rule. Every sentence earns its place; the list is necessary because it provides the exact wording to present to the user.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The description covers the interaction flow, focus handling, and generation guidance. However, it is slightly ambiguous whether the tool itself generates the topics or expects the agent to populate the 'topics' parameter, which is part of the input schema. This missing explicit clarification prevents a perfect score.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters5/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Even though schema coverage is 100%, the description adds essential semantics: it maps the user's answer to the 'focus' enum values, explains the 'awareness' special case (skip topics, set brief), and clarifies that topics should be weighted toward the focus theme. This is meaningfully beyond the schema descriptions.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description opens with a specific verb and resource: 'Auto-generate feedback questions for a prototype based on what was built.' This clearly distinguishes it from sibling tools like get_feedback (retrieval) and triage_feedback (categorization).
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides clear context and a step-by-step process: ask the user for focus, present options, use the answer as the 'focus' parameter, and generate 3-5 questions. It does not explicitly compare against alternatives, but the workflow implies when this tool should be used.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden. It discloses default behavior (standalone), the versioning option, the user-confirmation requirement, and the return URL. While it doesn't mention every possible side effect, it covers the key behavioral constraints and output clearly.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Three concise sentences, front-loaded with the main action, then conditional behavior, an important note, and the return value. Every sentence earns its place with zero fluff.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a complex 7-param tool with no annotations or output schema, the description provides essential context: default behavior, versioning option, user-confirmation requirement, procedural prerequisite, and return URL. Since the schema fully documents parameters, the description completes the picture effectively.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, so the baseline is 3. The description adds contextual meaning by explaining the two creation modes (standalone vs. parent_project_id) and the resolve_target prerequisite for collection/project, enhancing understanding of parent_project_id and collection_id beyond the schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states 'Register a prototype on VibeSharing' with a specific verb and resource, and distinguishes between standalone creation and versioning under an existing project via parent_project_id. This differentiates it from siblings like deploy_prototype and upload_source.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines5/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
It explicitly instructs to use resolve_target before calling to confirm collection and project name, and warns against auto-generating names without user confirmation. This provides clear when-to-use guidance and an explicit prerequisite alternative.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
