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

While annotations indicate openWorldHint=true and readOnlyHint=false (suggesting external interactions and state modification), the description adds valuable context about the internal decision-making mechanism (three specific analytical personas) not found in structured fields. However, it fails to clarify what external systems are contacted (via webhook_url) or what state is persisted (implied by session_context and readOnly=false).

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

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

The description consists of two highly efficient sentences. The first establishes the conceptual model ('Tradeoff assessment council'), and the second details the methodology, evaluation dimensions, and output format. Every phrase carries semantic weight with no redundancy or filler.

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

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

Given the presence of complex infrastructure parameters (webhook_url, session_context) and annotations indicating non-idempotent external interactions, the description adequately covers the core analytical behavior but leaves significant gaps regarding side effects, persistence mechanisms, and the asynchronous webhook behavior implied by the parameter schema.

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

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

With 100% schema description coverage, the parameters are well-documented in the schema itself. The description implicitly references the 'options' parameter and illustrates the types of tradeoffs considered (which loosely map to 'priorities'), but does not explicitly explain parameter relationships, validation rules, or provide usage examples beyond what the schema already contains.

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

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

The description clearly establishes the tool's function using the 'Pragmatist, Skeptic, and Futurist' personas to evaluate options across specific dimensions (short-term vs long-term, risk vs reward, simplicity vs flexibility), and specifies the output format as 'pros-cons'. However, it relies on metaphorical framing ('council') without explicitly contrasting with the similar 'consult-council' sibling tool.

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

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

The description provides no guidance on when to select this tool versus alternatives like 'consult-council', 'design-architecture', or 'plan-implementation'. It lacks explicit prerequisites, exclusion criteria, or scenario-based recommendations for usage.

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

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

Annotations declare read-only, idempotent, safe operations. Description adds value by specifying returned data types (credits, limits, plan info) but omits cache behavior, rate limit costs, or authentication scope beyond what annotations provide.

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

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

Extremely efficient at 9 words. Front-loaded with action and resources. No filler or redundancy; every word earns its place.

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

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

Appropriate for a simple metadata tool. Output schema exists (reducing need to describe return values), annotations cover safety profile, and description identifies the domain. Could improve by noting if this reflects real-time or cached data.

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

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

Schema coverage is 100% with the 'verbose' parameter fully documented. Description mentions no parameters, but baseline 3 is appropriate since the schema carries the full semantic burden adequately.

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

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

Clear verb 'Check' with specific resources (credits, usage limits, plan info). Distinct from sibling tools which focus on code, architecture, and debugging. However, lacks explicit differentiation text comparing to alternatives like get-session.

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

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

No guidance on when to use versus alternatives, prerequisites, or frequency recommendations. Description states what it does but not when an agent should invoke it.

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

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

Adds valuable process context beyond annotations (sequential discussion flow, moderator synthesis, auto-routing logic). However, fails to disclose operational traits implied by parameters: that it creates a session/thread (see siblings get-session/get-thread-link), async webhook behavior, or cost/latency implications of multi-model calls.

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

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

Four sentences, front-loaded with core mechanism. Every sentence earns its place: (1) what it does, (2) default behavior, (3) override path, (4) configurability scope. No redundancy.

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

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

Adequate for input configuration given rich schema, but incomplete regarding output behavior: no output schema exists, yet description doesn't clarify return structure (synthesis format) or session lifecycle implications critical for an agent invoking an async/multi-step tool.

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

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

With 100% schema coverage (baseline 3), the description adds conceptual framework linking auto_route and models parameters into 'auto-mode' vs 'manual mode' paradigm, helping agents understand the relationship between these settings.

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

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

Specific verb ('consult') + resource ('AI coding council') + mechanism ('multiple models discuss sequentially... moderator synthesizes'). Clearly distinguishes from siblings like 'review-code' or 'design-architecture' by emphasizing the multi-model debate/discussion pattern.

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

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

Provides operational guidance distinguishing auto-mode (default) from manual mode ('Provide explicit models to override'), but lacks explicit guidance on when to select this tool vs siblings like 'assess-tradeoffs' or 'design-architecture' for engineering problems.

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

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

Annotations indicate readOnlyHint=false and openWorldHint=true, but the description doesn't clarify what side effects occur (e.g., whether debugging sessions are persisted, what the webhook receives, or that external URLs in the knowledge parameter will be fetched). It adds context about the collaborative 'council' process but omits critical behavioral details an agent needs to use the tool safely.

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

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

The description is brief (two sentences) but inefficiently structured. The first sentence 'Debugging council.' is a content-free fragment that restates the title. The second sentence is information-dense but front-loading the personas before the action creates slight cognitive overhead for the agent parsing intent.

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

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

For a complex tool with 8 parameters including webhooks, session context references, and external knowledge injection, the description is underspecified. It fails to explain the interaction pattern (async via webhook vs sync), the role of session_context, or what output to expect (no output schema exists). While the schema documents individual parameters, the description doesn't tie them together into a complete operational picture.

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

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

With 100% schema description coverage, the schema fully documents all 8 parameters including complex nested objects (knowledge) and enums (thinking_level). The description text adds no parameter-specific guidance, syntax details, or examples, earning the baseline score of 3.

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

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

The second sentence provides specific verbs (diagnose, analyze, propose) and resources (bugs, errors, fixes), while the persona list (Root Cause Analyst, Systems Engineer, Edge Case Investigator) suggests a specialized multi-agent approach. However, the first sentence 'Debugging council.' merely restates the concept without adding value, and the description doesn't explicitly differentiate this from the sibling 'consult-council' or 'review-code' tools.

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

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

The description provides no guidance on when to select this tool versus siblings like 'consult-council' (general advice) or 'review-code' (code review). It doesn't mention prerequisites (e.g., having error messages or code snippets ready) or when the webhook parameter should be utilized.

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

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

Annotations indicate openWorldHint=true and readOnlyHint=false. The description adds valuable behavioral context not in annotations: the computational cost ('high thinking'), the collaborative multi-agent nature of the evaluation, and the specific output format (ADR). It does not contradict the annotations.

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

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

The description is three sentences with zero waste. It front-loads the core concept (architecture council), follows with specific roles and action, then adds operational characteristics (high thinking) and output format. Every clause earns its place.

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

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

For a complex multi-agent tool with webhook support (implying potential async operation), the description is minimally adequate. It notes the ADR output but does not explain the webhook's role in async delivery versus synchronous return, nor does it define ADR for users unfamiliar with the acronym.

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

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

With 100% schema description coverage, the schema adequately documents all parameters (description, scale, tech_stack, focus_areas, webhook_url). The description does not add parameter-specific semantics, but this is acceptable given the comprehensive schema documentation, meeting the baseline for this dimension.

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

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

The description clearly identifies the specific multi-persona 'council' structure (Systems Architect, Infrastructure Engineer, DX Advocate), the action (evaluate system design), and deliverable format (ADR). This effectively distinguishes it from the generic 'consult-council' sibling and tradeoff analysis tools.

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

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

The description provides one explicit usage signal ('Always uses high thinking for maximum depth'), suggesting when to use it for deep analysis. However, it lacks explicit guidance on when NOT to use it (e.g., for quick/simple questions) and does not mention alternatives like 'assess-tradeoffs' for narrower scope decisions.

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

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

Annotations already declare read-only, idempotent, non-destructive behavior. Description adds valuable context about data source (MCP tool executions) and available filter dimensions, but omits behavioral details like pagination behavior, log retention, or result ordering.

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

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

Three well-structured sentences: purpose/scope, capabilities, and use cases. No redundancy or waste. Information is front-loaded with the core action.

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

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

Appropriate for complexity: covers data source, filtering capabilities, and use cases. With output schema present and rich annotations, description doesn't need to detail return values. Minor gap: could note that all filters are optional (0 required params).

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

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

With 100% schema description coverage, baseline is 3. Description adds semantic grouping by mapping parameters to filter categories (session, severity level, event type, time range), but does not add syntax details, examples, or constraints beyond the schema.

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

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

Description uses specific verb 'Query' with clear resource 'structured logs from your MCP tool executions', distinguishing it from sibling tools like get-session (metadata) or debug-issue (procedural debugging).

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

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

Provides implied usage contexts ('Useful for debugging and monitoring tool usage') but lacks explicit when-to-use guidance versus similar siblings like debug-issue or check-usage, and does not specify prerequisites or exclusions.

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

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

While annotations cover safety (readOnlyHint, idempotentHint), the description adds valuable context about the return content ('participant responses and moderator synthesis') that helps the agent understand what data to expect beyond the schema structure.

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

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

Three sentences with zero waste: purpose declaration, return value details, and prerequisite workflow. Information is front-loaded with the action verb.

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

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

Given the presence of an output schema, the description appropriately focuses on purpose and workflow. It mentions the key components of the result (participant responses, moderator synthesis) without redundantly detailing the full schema structure.

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

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

With 100% schema description coverage for the single 'session_id' parameter, the schema carries the semantic load. The description implies the ID refers to a 'previous MCP session' but doesn't elaborate beyond the schema definition.

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

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

The description states the specific action ('Get full details'), resource ('MCP session'), and scope ('by ID'), clearly distinguishing it from sibling 'list-sessions' which finds IDs rather than retrieving full details.

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

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

Explicitly states the workflow dependency: 'Use list-sessions first to find session IDs,' providing clear guidance on when to use this tool versus its sibling.

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

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

Annotations cover safety (readOnly, idempotent), but the description adds valuable behavioral context: it discloses the conditional return of 'public URL if the thread is public,' which is critical information not found in annotations.

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

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

Two efficient sentences: the first establishes the core action (get dashboard URL), the second clarifies return behavior (conditional public URL). No redundancy or waste.

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

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

Given the simple single-parameter input, existing annotations, and presence of an output schema, the description provides adequate completeness by covering the conditional return logic. Minor gap: no mention of error behavior for invalid session IDs.

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

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

With 100% schema coverage, the baseline is 3. The description adds context that the session_id refers to a 'previous debate session,' qualifying the parameter beyond the schema's basic description.

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

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

The description clearly states the tool retrieves a 'dashboard URL for a previous debate session' and distinguishes itself from sibling get-session by focusing specifically on link/URL retrieval rather than session content.

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

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

While the description implies usage (when you need the thread link vs. session data), it lacks explicit guidance on when to prefer this over get-session or prerequisites like session existence checks.

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

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

Annotations already declare readOnly/idempotent/destructive hints, so safety is covered. The description adds valuable business logic context: it discloses that results include 'credit costs' (billing implications), 'default models', and 'capabilities for each tier'—information beyond what annotations provide.

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

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