Server Quality Checklist

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

Latest release: v1.0.22
Disambiguation5/5
Each tool targets a distinct aspect of the validation pipeline—row management, job control, configuration, results, and account info—with no overlapping purposes. Even similar tools like add_pending_row vs add_validated_rows are clearly differentiated by stage.
Naming Consistency5/5
All 25 tool names follow a consistent verb_noun pattern (e.g., add_pending_row, get_results, wait_for_job). The naming is uniform and predictable, making it easy to infer functionality.
Tool Count4/5
With 25 tools, the set is on the higher side but each tool is justified by the server's comprehensive workflow (upload, config, preview, editing, validation, results, updates, and account management). Some consolidation of polling tools might be possible, but overall the count is reasonable for the scope.
Completeness5/5
The tool surface covers the entire lifecycle: file upload, table configuration, preview, structural editing, approval, full validation, result retrieval, post-validation updates, and even reference checking. Account tools (get_balance, get_usage) are also included, leaving no obvious gaps for the stated domain.
Average 4.4/5 across 25 of 25 tools scored. Lowest: 3.5/5.

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?
Description says 'update in place' implying modification, consistent with readOnlyHint=false. However, no additional behavioral details beyond annotations; no mention of overwrite behavior 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.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two terse sentences, no fluff, critical info front-loaded. Every word contributes.
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?
Output schema exists, so return values are covered. However, the description omits what 'update in place' means for previous results (overwrite vs new version). Functional but leaves some questions for a validation 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 coverage is 100% with adequate parameter descriptions. Description adds context for source_version ('pin...latest'), but largely redundant with schema. 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?
Description clearly states 'Re-run validation on a previously processed table', specifying verb and resource. No ambiguity; distinguishes from siblings like add_validated_rows.
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?
Provides guidance on the source_version parameter but lacks explicit when-to-use vs alternatives. Implied for re-running validation, but could contrast with add_validated_rows or start_table_validation.
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?
Annotations already declare readOnlyHint=true, making the behavioral expectations clear. The description adds a date format hint but does not discuss other behaviors like pagination or rate limits, which are not covered by annotations.
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 communicate purpose and a key format detail with no wasted words.
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 presence of an output schema and annotations, the description covers the essential purpose and date format. It could detail what constitutes 'usage history' but remains adequate for a read-only list 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 description coverage is 100%, so the description does not need to compensate. The date format hint redundantly reinforces parameter descriptions, adding no new meaning.
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 'Return API usage history', which specifies a verb and a resource. The purpose is distinct from sibling tools like get_balance or get_conversation.
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?
The description provides no guidance on when to use this tool versus alternatives. It lacks any context about suitable scenarios or prerequisites.
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?
Annotations already indicate readOnlyHint=true, so the description adds the unit 'in USD' and 'current' but no further behavioral traits. With annotations present, the description provides adequate context beyond what is structured.
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?
A single, front-loaded sentence efficiently states the tool's purpose without 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 zero parameters and presence of an output schema, the description suffices. It conveys the essential information (balance retrieval in USD) for a read-only tool.
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?
No parameters exist, so the baseline is 4. The description clarifies the return value (balance in USD), which adds meaning beyond the empty input schema and complements the output 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 uses a specific verb ('Return') and resource ('account credit balance'), clearly indicating what value is retrieved. It stands out among sibling tools like get_usage which likely returns different information.
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 for checking balance but does not provide explicit when-to-use or when-not-to-use guidance. For a zero-parameter tool, this is minimally acceptable.
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?
Annotations already declare readOnlyHint true. Description adds minimal behavioral context (live, running job) but no extra safety or side-effect details beyond annotations.
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 with a clear front-loaded purpose and no wasted words.
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?
With an output schema present, the description adequately covers purpose and key parameter usage, though it could optionally clarify behavior when since_seq is omitted.
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?
Input schema has 100% coverage, so baseline 3. Description reiterates the since_seq behavior but does not add new meaning 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 the verb 'Fetch' and the resource 'live progress messages for a running job', distinguishing it from siblings like get_job_status which focus on overall status.
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?
Provides a clear usage hint for the since_seq parameter to fetch only new messages, but does not explicitly mention when not to use or compare to 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?
Discloses that the tool triggers a stateful action (openWorldHint=true) and requires polling for AI response, adding value beyond annotations. However, does not detail rate limits, authentication needs, or potential delays.
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: one for purpose, one for next step. No redundant or vague phrasing; efficient and clear.
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?
Tool is straightforward and the description, combined with annotations and output schema (not shown but present), covers key behavioral aspects. Explains the polling pattern, which is critical for correct usage.
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?
Input schema covers 100% of parameter descriptions, so the description adds no additional parameter semantics. 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?
Description clearly states the action (send a user reply) and context (ongoing conversation, interview or table-maker). Distinguishes from sibling tools like get_conversation and wait_for_conversation, which serve different purposes.
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?
Provides explicit instruction to poll get_conversation after sending, guiding the agent on the expected workflow. Lacks explicit when-not-to-use or alternatives, but for a focused tool 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?
Adds behavioral context beyond annotations: no confirmation required and valid only before approval. This informs the agent about side effects and constraints without contradicting annotations.
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, no extraneous words, front-loaded with the core action. Every sentence provides essential 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?
With an output schema present and a simple tool (2 params), the description covers action, constraints, and timing. Could mention error conditions, but overall adequately 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?
Schema descriptions cover both parameters (session_id and row_key) completely. The description does not add additional semantic value beyond what the schema provides, so baseline score 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 uses the specific verb 're-include' and resource 'row', clearly stating the action. It naturally distinguishes from sibling 'exclude_row' by implying the opposite operation.
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 states no confirmation needed and the timing constraint ('at any point before approving the full validation run'). While it doesn't list alternatives, the context is sufficient for typical use.
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?
Annotations provide basic traits (non-readonly, non-destructive). The description adds specific behavioral details: 'clears skip_auto_preview and queues the preview.' This goes beyond annotations and gives the agent a better understanding of 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.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is three sentences, each serving a distinct purpose: stating the action, clarifying context, and explaining behavior plus next step. 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 low complexity (single param, output schema exists), the description covers purpose, usage context, behavioral effect, and next step. It lacks mention of return values but is otherwise 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?
Schema description coverage is 100%, with the session_id parameter already described as 'Session ID to trigger preview for.' The description does not significantly elaborate beyond that, but it reinforces usage context by mentioning session_id in the follow-up step. 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 clearly states the verb 'Trigger a preview run' and specifies the resource ('preview run') and context ('after structural editing is complete'). It distinguishes itself from sibling tools by mentioning it is called after row/column edits, providing explicit examples.
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 instructs when to call this tool ('after finishing row/column edits') and provides follow-up steps ('call wait_for_job(session_id) to track progress'). While it does not mention alternatives or when not to use, the guidance is clear and actionable.
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?
Annotations (readOnlyHint=false, destructiveHint=false) indicate mutability but non-destructiveness. The description adds nuance: 'source Excel is NOT modified' and 'fully reversible before approving the full run', clarifying the session-level mutability. This extra context is valuable and consistent with annotations.
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 extremely concise (4 sentences) with front-loaded action statement. Each sentence adds essential context: purpose, in-memory behavior, reversibility, and cost update. No superfluous 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's complexity (4 parameters, output schema exists), the description fully covers behavioral context: non-modification, session storage, reversibility, and cost impact. The agent can understand the tool's role and side effects without needing additional explanation.
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?
Input schema covers all 4 parameters with descriptions (100% coverage). The description does not elaborate on parameters beyond the schema, but baseline is 3 due to schema coverage. No additional semantic value is provided by the description.
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 specifies the action ('Add a new entity as a pending row') and the context ('to be included in the full validation run'). This distinguishes it from siblings like 'add_validated_rows' (adds pre-validated rows) and 'include_row' (re-includes excluded rows), providing 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 explains the tool's behavior (no modification to source Excel, stored in session state, reversible before approval) which gives clear context for when to use it. It implicitly advises against using it for permanent modifications, though it lacks explicit 'do not use when' guidance or direct sibling comparison.
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?
Annotations indicate non-readonly, non-destructive, open-world. Description adds auto-preview behavior and the effect of defer_preview. Does not detail persistence or rollback, but adds useful behavioral context.
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 terse paragraphs: purpose with examples, then defer_preview guidance. No excess words. Highly efficient.
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?
Assumes existence of conversation/session (required params) but does not explain lifecycle context (e.g., must have started refinement via start_table_validation). Output schema exists so return values not needed, but prerequisites are implicit.
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% with clear descriptions. Description adds example instructions and clarifies defer_preview usage beyond schema (e.g., 'prevents premature auto-preview'). Baseline 3 improved to 4.
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?
Description clearly states the verb 'refine' and resource 'validation config', with natural language instructions. Examples provided distinguish from sibling tools like 'start_table_validation' or 'approve_validation'.
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?
Provides specific guidance on when to set defer_preview to avoid premature auto-preview. However, does not explicitly compare to sibling tools for granular edits (e.g., exclude_row, add_pending_row) that might be alternatives.
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?
Annotations already indicate the tool is not read-only and not destructive, but the description adds transparency by detailing the conversation initiation and the auto_start behavior, which skips confirmation steps. It does not contradict annotations.
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, front-loaded with the purpose, includes a clear example, and explains parameters efficiently. Every sentence serves a purpose without redundancy.
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's complexity, the description covers the main parameters and usage. With an output schema present (as per context signals), the description does not need to explain return values. It is complete for effective tool invocation.
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%, but the description adds value by providing examples for the message parameter and clarifying when to use auto_start. This goes beyond the schema descriptions, which are already adequate.
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 starts a Table Maker conversation for generating research tables, using a specific verb and resource. It provides an example and distinguishes itself from sibling tools like start_reference_check or start_table_validation by its 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 Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description explains how to use the tool, including the auto_start parameter behavior, but does not explicitly mention when to use it versus alternatives or when not to use it. It lacks guidance on prerequisites or exclusion criteria.
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?
Annotations indicate mutation (readOnlyHint=false) and non-idempotent (idempotentHint=false). The description adds behavioral context: it starts full validation processing and requires exact cost confirmation to prevent accidental billing. No contradictions with annotations.
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, using short sentences and a clear workflow structure (numbered steps). Every sentence adds value without unnecessary detail.
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 presence of an output schema (not shown) and good annotations, the description covers the tool's purpose, parameters, and workflow. It could briefly mention what happens after approval (e.g., the job transitions to a new state), but is otherwise complete for an agent.
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% with good descriptions. The description adds extra value by clarifying that 'job_id' is the same as 'session_id' and emphasizing that 'approved_cost_usd' must exactly match the estimated cost. This goes beyond the schema's basic 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 'Approve a preview and start full validation processing,' specifying a specific verb and resource. It distinguishes from sibling tools like 'trigger_preview' and 'wait_for_job' through the workflow mention.
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 workflow steps: call 'wait_for_job' first to reach preview_complete, then call 'approve_validation' with the exact cost. It explains the reason for requiring 'approved_cost_usd' to match the estimate, but does not explicitly mention when not to use the tool or alternatives.
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?
Annotations already declare readOnlyHint=true, indicating a safe read operation. The description adds behavioral context by explaining that the tool returns intermediate statuses and suggests polling intervals. However, it does not disclose auth requirements or rate limits, which would further enhance transparency.
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 very concise: one opening sentence plus a bullet list of three statuses. Every sentence adds value, and the structure front-loads the key action. There is no redundancy or fluff.
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 that an output schema exists (as per context signals), the description does not need to detail return values. It covers the main use case, statuses, and follow-up actions. It could mention polling timeout or when to stop, but it is sufficiently complete for a polling tool with sibling 'wait_for_conversation' for automatic polling.
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 input schema already documents both parameters. The description adds no additional parameter details beyond what is in the schema (e.g., 'Conversation ID returned by...'). Per the rubric, baseline is 3 when coverage is high, and the description does not add meaningful extra semantics.
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 purpose: 'Poll a conversation for new messages or a status change.' It specifies the verb 'poll' and the resource 'conversation', making the action unambiguous. The list of key statuses further distinguishes this tool from siblings like 'send_conversation_reply' and 'get_job_status'.
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 guidance on when to use the tool (polling for new messages or status change) and includes specific statuses with recommended actions: 'poll again in ~15s', 'send_conversation_reply', and 'switch to get_job_status'. This gives clear context for alternative tools, exceeding basic usage 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?
Annotations already indicate readOnlyHint=true. Description adds value by listing what is returned (preview table, excluded rows, pending rows, ignored columns, row order) and the purpose (review). No contradiction.
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, each serving a purpose: state action, list return items, state usage context. No extraneous information. Front-loaded with the verb and resource.
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?
Despite having an output schema, the description still explains the key components returned. For a simple read-only tool with one parameter, this is complete and sufficient guidance.
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 has 100% coverage with a single parameter 'session_id' described only as 'Session ID.' Description does not add additional semantics about the parameter beyond what the schema provides, so 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?
Clearly states 'Get the current structural editing state of a session,' specifying the action (get), resource (preview state), and scope (session). Distinguishes from sibling tools like 'trigger_preview' and 'add_pending_row' which modify state.
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 to use it 'before triggering the full validation run' to review current state. Does not mention alternatives or when not to use, but the context is clear enough for an AI 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?
Adds value beyond annotations by revealing that table_metadata.json is automatically embedded, avoiding separate HTTP fetches. Also outlines key response fields. Annotations already indicate readOnlyHint=true, so the description complements without contradiction.
