Server Quality Checklist

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

Latest release: v3.11.0
Disambiguation4/5
Most tools have distinct purposes, but there is some overlap among similar actions like generate_diagram vs generate_all_diagrams, and multiple 'check' tools. Detailed descriptions help resolve ambiguity.
Naming Consistency5/5
All tools follow a consistent 'sdd_<verb>_<noun>' pattern using snake_case. Verbs are uniform and predictable across the entire set.
Tool Count3/5
With 58 tools, the count is high for a typical MCP server but may be justified by the comprehensive SDD pipeline it supports. Still borders on being overwhelming.
Completeness5/5
The tool surface covers the full SDD lifecycle from initialization to testing and documentation generation. Only minor gaps exist (e.g., direct artifact deletion), but the core workflow is well-covered.
Average 3.9/5 across 58 of 58 tools scored. Lowest: 3.1/5.

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?
The description adds no behavioral detail beyond what annotations (all false) imply. It says 'writes' but does not clarify side effects (e.g., file creation, overwriting behavior, error handling). With destructiveHint false, the absence of explanation about controlled overwriting (via force parameter) is a gap.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, front-loaded sentence of 20 words that covers the main purpose. It is concise but could be more structured (no bullet points or sections). However, the brevity does not sacrifice clarity significantly.
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?
Given the tool has 5 parameters, no output schema, and no explicit success/error descriptions, the description leaves gaps. It does not explain what the tool returns (e.g., path of written file) or behavior when file exists. The description is incomplete for an agent to fully understand the tool's effects.
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 baseline is 3. The description mentions 'pre-implementation gates' and 'parallel markers' which map to schema parameters, but it does not add extra meaning beyond the schema definitions. The parameter semantics are adequately explained in 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 that the tool generates and writes TASKS.md with specific content (gates, parallel markers, effort estimates, traceability). It uses a specific verb+resource combination and distinguishes from sibling tools like sdd_verify_tasks or sdd_write_spec by focusing on writing the task breakdown file.
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 (e.g., sdd_verify_tasks, sdd_write_spec). It does not mention prerequisites or scenarios where this tool is appropriate. An AI agent would need to infer context from the tool name and siblings alone.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior1/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description states the tool writes COMPLIANCE.md, which contradicts the annotation readOnlyHint=true. This is a serious inconsistency, as a write operation cannot be read-only.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, concise sentence that front-loads the key action and scope. It is efficient but could be slightly more structured without adding length.
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 the main action but does not explain the return value, error handling, or prerequisites (e.g., existence of spec files). Given the absence of an output schema, more information would be beneficial.
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 does not add additional meaning beyond what the schema already provides for each parameter. 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 explicitly states the tool validates specification and design against specified compliance frameworks and writes a COMPLIANCE.md file. This clearly distinguishes it from other sibling tools like generic validation or generation tools.
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 compliance checking but does not specify when to use this tool versus alternatives, nor does it mention prerequisites or when not to use it.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations provide no safety info (readOnlyHint false, no destructiveHint). Description mentions writing a file, but does not disclose overwrite behavior (though force param exists), naming conventions, or side effects (e.g., file creation in .specs dir). For a write operation, more behavioral context is needed beyond 'generates and writes.' No contradiction 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?
Single sentence, no fluff. Lists key output contents. Appropriate length given complexity. Front-loaded with purpose.
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?
With 16 parameters (2 required), no output schema, and no additional context, the description is too brief. It lacks explanation of default directory (.specs), feature_number naming, and how optional parameters combine. Agents need more context to invoke correctly, especially for a design document generation 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 has 100% coverage, with each parameter described. Description adds no extra meaning beyond that. Baseline 3 is appropriate as schema does the work, and description does not enhance parameter understanding.
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 tool generates and writes DESIGN.md with specific content (architecture overview, Mermaid diagrams, ADRs, API contracts). Verb 'writes' is specific, and resource 'DESIGN.md' is explicit. This distinguishes it from siblings like sdd_write_spec (which likely writes spec docs) and sdd_generate_docs (which may generate multiple docs).
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 on when to use this tool vs alternatives (e.g., sdd_write_spec, sdd_implement). No prerequisites mentioned, no conditions for use. Agents must infer usage from context. Lack of when-not-to-use or alternative references limits effective selection.
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 lack behavioral hints (readOnlyHint=false, destructiveHint=false, etc.), so the description must carry the burden. It mentions writing a file but does not disclose overwrite behavior, failure conditions if input files are missing, or error handling. The agent cannot infer side-effect risks.
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 fluff. The first sentence states the purpose and inputs, the second the output location. Perfectly front-loaded and 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?
With 2 parameters and no output schema, the description covers inputs and output location adequately but lacks details on side effects (overwrite, error on missing files). It is minimally complete but leaves behavioral 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 both parameters. The description adds little beyond what the schema provides; 'feature_number' pattern and 'spec_dir' default are already clear. 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 'generates' and the resource 'comprehensive feature documentation', listing specific input files and output location. It distinguishes from sibling doc generation tools by specifying the exact inputs and output.
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?
There is no guidance on when to use this tool versus other doc generation siblings like sdd_generate_api_docs or sdd_generate_all_docs. The description implies a context but does not provide explicit when/when-not or alternative recommendations.
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 mutability (readOnlyHint=false) and idempotency; description adds context on auto-detection and output routing but does not specify if files are created or what side effects occur.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences, no fluff, but the first sentence is somewhat dense; still efficient overall.
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?
Lacks details about output payload structure and idempotency behavior; without an output schema, the description should more thoroughly explain return value.
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 parameter descriptions; description adds value by explaining auto-detection of services from DESIGN.md and format of feature_number.
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 detects tech stack and generates Docker-based environment, but does not differentiate from siblings like sdd_generate_devcontainer or sdd_generate_dockerfile.
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 explicit guidance on when to use this tool versus alternatives; the description only implies usage for setting up a local dev environment.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior1/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description states the tool writes VERIFICATION.md, which is a write operation, contradicting the annotation readOnlyHint=true. This is a clear annotation contradiction. The description does not disclose the side effect of file writing 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.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is three sentences with no fluff. Each sentence adds distinct information: reading TASKS.md, checking code paths, detecting phantom completions, and writing output.
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?
No output schema is provided. The description mentions writing VERIFICATION.md but does not explain its content or format. Given the tool's verification purpose, more detail on the output would be beneficial. Annotations partially fill gaps but not completely.
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 descriptions for all three parameters. The description adds context about TASKS.md but does not significantly enhance parameter understanding beyond the schema. 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 clearly states the tool reads TASKS.md, checks code paths for implementation evidence, detects phantom completions, and writes VERIFICATION.md. The verb-resource combination is specific and distinguishes it from siblings like sdd_verify_tests.
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 tasks need verification after implementation, but does not explicitly state when to use or not use it compared to alternatives. No exclusions or context are provided.
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 are minimal (no readOnly, destructive, idempotent hints). Description adds that the tool produces a file and is not gated by state machine. However, it does not disclose whether it overwrites existing files or other 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?
Single sentence that is front-loaded with the main action and output file name. No wasted words.
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?
Given 8 parameters, no output schema, and only 3 required, the description could explain the return format or file path behavior more explicitly. It covers the 'what' but not the 'how' of output.
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 summarizes the output sections, but does not add meaning beyond the parameter names and schema descriptions.
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 generates and writes a BUGFIX_SPEC.md file with specific sections. It is distinct from sibling write tools (e.g., sdd_write_design) through the bugfix context, but does not explicitly differentiate.
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 on when to use this tool versus alternatives like sdd_write_spec or sdd_write_design. The only added info is 'Not gated by the state machine,' which is a constraint but not usage direction.
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 convey read-only, non-destructive, idempotent behavior. The description does not contradict annotations but adds minimal behavioral context beyond what annotations provide. It does not disclose any side effects or additional constraints.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences, front-loaded with action, no unnecessary words. However, could be slightly more concise by integrating diagram types list into sentence.
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, the description could mention return value. It adequately covers purpose and diagram types but lacks guidance on usage and output. Adequate for a 4-parameter read-only 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 schema itself documents parameters well. The description lists diagram types but adds no new semantic meaning beyond the schema. 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 clearly states the tool generates a single Mermaid diagram from a specification artifact, and lists all 17 supported diagram types. It distinguishes from sibling tools like sdd_generate_all_diagrams which generates all diagrams.
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 on when to use this tool vs alternatives. There is no mention of when to use a single diagram vs generating all diagrams, or when to use different source artifacts. Missing context for appropriate usage.
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 all false, so description carries full burden. It mentions generating and writing a file but lacks details on idempotency (overwrite vs. append), side effects, or prerequisites. Minimal behavioral 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 a single sentence that efficiently conveys purpose and output. No unnecessary words or redundancy.
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?
No output schema exists, but the description does not clarify what the tool returns (e.g., confirmation, file path). It also omits behavior when the target file already exists. Incomplete for a file-generating 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% and both parameters are described in the schema. The description adds no extra semantic information beyond what is already in 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 it generates an operational runbook with specific sections (deployment, monitoring, troubleshooting, rollback) and specifies the output file pattern. This distinguishes it from sibling generation tools like sdd_generate_docs.
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 creating runbooks for features but provides no explicit guidance on when to use this tool versus alternatives like sdd_generate_docs or sdd_generate_api_docs. No when-not or alternative examples.
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 are not contradictory, but lack detail. Description mentions file generation and validation, but does not disclose side effects (e.g., overwriting via force parameter) or error handling.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences, 15 words, no fluff. Front-loaded with core purpose.
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?
Adequate for a tool with 6 parameters and no output schema. Covers main function but does not explain return values, validation details, or file behavior.
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%. Description adds value by specifying that requirements must be in EARS notation and that validation occurs, which is not fully captured in schema descriptions alone.
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?
Clearly states the tool generates and writes SPECIFICATION.md with EARS notation requirements and validates them. Distinguishes from siblings like sdd_validate_ears, but does not explicitly contrast with alternatives.
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 on when to use this tool vs alternatives like sdd_turnkey_spec or sdd_write_design. No context on prerequisites or constraints.
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 indicate potential state changes (readOnlyHint=false) and non-destructive nature (destructiveHint=false). The description adds that it runs an 'auto-pipeline' and creates 'feature spec packages' but does not detail side effects, resource usage, or error behavior. The description adds moderate value 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?
The description is two sentences, front-loaded with the core function followed by context. Every sentence earns its place with no redundancy or fluff.
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?
Given no output schema, the description hints at output ('each transcript becomes its own feature spec package') but does not explain return format, error handling, or limitations. For a batch tool, more details on concurrency or file size limits would improve completeness. The description is adequate but not thorough.
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 has 100% description coverage with clear parameter descriptions. The description adds no further parameter meaning beyond stating that each transcript becomes a spec package. Baseline 3 is appropriate as schema already provides sufficient semantics.
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 it scans a folder for transcript files and runs the full SDD auto-pipeline for each, with specific file types listed. It provides context about Power Automate and OneDrive workflows, making the purpose clear. However, it does not explicitly distinguish from sibling tools like sdd_auto_pipeline, though 'batch' implies multiple files.
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 mentions a typical use case (Power Automate + OneDrive workflows) but does not specify when to avoid using this tool or mention alternatives. It implies batch processing but lacks explicit guidance on prerequisites or when to choose batch over single-file tools.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior1/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description claims 'Writes CROSS_ANALYSIS.md', indicating a file creation side effect, which contradicts the readOnlyHint=true annotation. This is a serious inconsistency. Additionally, no further behavioral traits (e.g., permissions, rate limits) are disclosed, and annotations already cover safety but are contradicted.
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 direct, front-loaded content: purpose, artifacts checked, findings, and output file. No redundant or extraneous information.
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, the description should explain what the tool returns or how to interpret the analysis result. It only says 'Writes CROSS_ANALYSIS.md' but does not describe the tool's return value or behavior if files are missing. Adequate for core function but incomplete on response format.
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%, so the schema fully documents both parameters. The description does not add any extra meaning beyond the schema (e.g., no usage tips or format details), resulting in baseline value.
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 specific verb 'checks alignment' and identifies the specific resources (SPECIFICATION.md, DESIGN.md, TASKS.md) along with the outcomes (orphaned requirements, missing designs, untraced tasks) and output file (CROSS_ANALYSIS.md). This distinguishes it from sibling tools like sdd_verify_tasks or sdd_validate_ears.
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 implies usage when cross-artifact consistency is needed, but does not explicitly state when to use vs alternatives or when not to use. The context is clear enough for an agent to infer typical use cases, but lacks explicit exclusion criteria.
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, destructiveHint=false, idempotentHint=true, and openWorldHint=true. The description adds that it produces routing_instructions but does not elaborate on side effects or what the payload contains. With annotations present, the bar is lower, but the description could add context about file creation (given spec_dir and force parameters) which is absent.
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: the first states the purpose, the second provides usage instructions. It is appropriately sized, front-loaded, and every sentence adds value. No redundancy.
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?
Given 5 parameters with full schema coverage and annotations, the description is somewhat complete but lacks explanation of the tool's output format and the fact that it likely generates files (given spec_dir and force parameters). No output schema exists, so the description should provide more behavioral context. Adequate but has 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 coverage is 100% with each parameter having a description. The description does not add significant meaning beyond the schema; it mentions the concept of routing_instructions but doesn't tie into specific parameters. Baseline 3 is appropriate since the schema covers most details.
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 it prepares a structured payload for extracting design context from Figma, which is a specific verb+resource. It distinguishes itself from siblings by mentioning the production of routing_instructions for another tool, though it doesn't explicitly contrast with similar tools like sdd_figma_diagram.
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 the tool is a preparatory step before calling Figma MCP's get_design_context, but it does not provide explicit guidance on when to use this tool versus alternatives, nor does it mention when not to use it. Context is provided but lacks exclusions or conditional logic.
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 (readOnlyHint=false, destructiveHint=false) provide no safety info. The description mentions 'generates', implying file creation, but does not disclose potential side effects like overwriting existing files, or permissions needed. 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 efficient sentences: first defines action and source, second adds frameworks and traceability. No wasted words; ideal length.
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 core purpose and framework support, but lacks details on output format, when to use relative to siblings like sdd_generate_pbt, and expected behavior when spec files are missing. Given no output schema, more context would be valuable.
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%, so the baseline is 3. The description adds 'traces to a requirement ID', which is not in the schema, but this is marginal. The parameter descriptions in the schema already adequately convey 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 'Generate test stubs from acceptance criteria in SPECIFICATION.md and TASKS.md.', which provides a specific verb and resource. It distinguishes from siblings by focusing on test stubs and mentioning traceability, making it clear what the tool does.
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 test stubs are needed, but does not explicitly guide when to use this tool vs alternatives like sdd_generate_pbt or sdd_verify_tests. No exclusions or conditions are given.
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 indicate non-read-only and non-destructive behavior, and the description adds that the tool writes a file. However, it does not specify whether it overwrites existing RESEARCH.md or appends, nor does it disclose any side effects. This is adequate but leaves ambiguity about file creation behavior.
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 conveys the input, output, and action without redundancy. Every word is functional, and the most critical information is front-loaded. No wasted space.
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 explains the output structure (question, findings placeholder, etc.) but does not map 'feature directory' to the spec_dir parameter or mention prerequisites like existing directory. Given the tool's simplicity and no output schema, the description is minimally complete but lacks contextual details for error handling or path resolution.
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 three parameters (feature_number, spec_dir, questions) with descriptions, achieving 100% coverage. The description adds no new meaning beyond stating that questions are an array, which is already in the schema. While consistent, it does not enhance the agent's understanding 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 tool takes an array of research questions, generates a RESEARCH.md file with structured entries, and writes it to the feature directory. It specifies the verb ('takes', 'generates', 'writes'), the resource (RESEARCH.md with specific fields), and the action, making the 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 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, nor does it mention when not to use it. Without any usage context or exclusions, agents may misuse the tool for tasks better suited to siblings like sdd_write_spec or sdd_generate_docs.
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 not read-only and not destructive. The description adds that it writes to a specific file path, implying a side effect, but does not disclose overwrite behavior or permissions. Minimal additional context 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?
The description is concise (two sentences) and front-loaded with the tool's purpose and output. Every word adds value with no 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 (2 params, no output schema), the description covers the core functionality and output location. However, it lacks details on input sources (e.g., whether it requires an existing spec) and file handling behavior.
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 clear descriptions for both parameters. The tool description adds no extra semantic meaning beyond the schema, so baseline score 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 that the tool generates a developer onboarding guide with specific content (feature overview, architecture summary, etc.) and writes to a file. It distinguishes itself from sibling tools like sdd_generate_docs and sdd_generate_runbook by specifying its unique output.
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, nor any prerequisites or conditions. Siblings like sdd_generate_docs and sdd_generate_runbook exist but no differentiation is given.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, destructiveHint=false, and idempotentHint=true, establishing it as a safe, read-only operation. The description adds value by detailing the return content (phases, files, percentage, next action), but does not disclose any additional behavioral traits (e.g., whether it requires a running pipeline, rate limits, or side effects). No contradiction 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 a single, well-structured sentence that lists key return fields. No redundant or extraneous information. It is front-loaded with the core purpose ('Returns the current pipeline status') and efficiently details the content. Every word earns its place.
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 optional params, no output schema), the description adequately covers the return fields and intended use. It could be more complete by noting the return format (e.g., JSON) or potential error conditions, but for a basic status query, it provides sufficient context for an AI agent to use it correctly. Annotations cover safety fully.
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 has 100% description coverage for both parameters (spec_dir and feature_number), each with clear, self-explanatory descriptions. The tool description does not add any further semantic information beyond what the schema already provides. Baseline score of 3 is appropriate when schema does the heavy lifting.
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 explicitly states the tool returns 'current pipeline status' and lists specific fields (current phase, completed phases, etc.). It clearly distinguishes this from siblings like sdd_advance_phase (which advances the pipeline) and sdd_context_status (which might return context rather than pipeline status), making the purpose specific 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 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 (e.g., sdd_checkpoint, sdd_context_status). It only states what it does, without mentioning preconditions, exclusion criteria, or when not to use it. This lack of usage context limits its utility for an AI agent choosing between similar tools.
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 declare idempotentHint=true, and description confirms it only reads and returns questions. It adds 'up to 5' limit and targeting ambiguity, which is helpful but minimal 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.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
One sentence, 14 words, front-loaded with action and output. Very concise and clear, though could include brief usage hint without harming conciseness.
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 full schema descriptions and annotations, the description adequately covers purpose, input, and output. It could mention no side effects, but annotations already cover idempotency.
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 with descriptions (100% coverage). The description adds no additional meaning beyond what the schema already provides.

Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations indicate idempotentHint=true and destructiveHint=false, but readOnlyHint=false, which is ambiguous. The description does not clarify side effects (e.g., whether it modifies state or is purely read). No contradiction 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?
Two sentences, front-loaded with key purpose, no redundant information. Efficient and clear.
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?

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 are uninformative (all false). Description adds context: parallel generation and output to docs/ directory. However, it does not disclose idempotency, overwrite behavior, or resource usage beyond 'fastest'.
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, no fluff. First sentence states core purpose and lists types, second specifies output location, third gives value proposition. Front-loaded and efficient.
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?
Provides key expectations: parallel generation, output directory, coverage of all doc types. However, lacks details on error handling, prerequisites, or whether files are overwritten. Given simplicity, still adequate.
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 both parameters documented. The tool description adds no additional parameter information beyond the schema, so baseline score applies.

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 use for comprehensive doc generation ('fastest way to generate complete project documentation'), but does not explicitly state when to avoid or prefer alternatives. Sibling tools for individual doc types exist without exclusion 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?
Annotations already declare idempotentHint=true and destructiveHint=false. The description adds that the tool 'writes the file to disk', which is consistent with a non-destructive write. However, it does not mention overwrite behavior or potential side effects like modifying existing configs without confirmation. Given annotations cover safety profile, the description provides adequate but not exceptional 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?

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 explains the output file's contents (base image, features, extensions, port forwarding) and the detection mechanism. Without an output schema, this is sufficient for an agent to understand what the tool produces. However, it could mention that the tool creates the .devcontainer directory if missing.
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% as all four parameters have descriptions in the input schema. The description adds minimal extra meaning beyond the schema, only implying that features and base_image are configurable. Baseline 3 is appropriate since the description does not significantly enhance parameter understanding.
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 generates .devcontainer/devcontainer.json from the detected tech stack. It specifies the verb 'generates', the resource 'devcontainer config', and the source 'codebase manifests, falling back to DESIGN.md'. This is specific and distinct from sibling tools like sdd_generate_dockerfile.

Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool validates requirement statements against EARS notation patterns and lists the patterns. It distinguishes itself from sibling tools like sdd_validate_iac by focusing specifically on EARS requirements.
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 the two input modes (direct list vs. SPECIFICATION.md) but does not provide explicit guidance on when to use this tool versus alternatives or when not to use it. While the context signals show siblings for different validations, the description itself lacks this differentiation.
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, destructiveHint, idempotentHint, and openWorldHint, indicating a safe, non-destructive operation. The description adds that the tool generates a payload and does not execute validation, which is consistent but only marginally extends transparency 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?
The description is two sentences long, front-loads the core purpose, and contains no redundant information. Every sentence adds value.
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 generates a payload for external execution, the description covers the essential purpose and routing. However, it lacks hints about the output format (e.g., JSON structure) since no output schema is provided, leaving a minor gap.
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 all 5 parameters with descriptions and defaults, achieving 100% coverage. The description does not add any additional meaning beyond what the schema provides, so baseline of 3 is appropriate.

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 are all false, so the description carries full burden. It discloses that validation and transition occur, and the lgtm condition, but omits important behavioral details such as what happens on validation failure, reversibility, or permission requirements. Adequate but not comprehensive.
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 that front-load the core action and follow with a conditional nuance. Every word contributes meaning, no redundancy.
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 phase advancement tool, the description covers the key functionality and a notable conditional. However, it lacks explanation of what constitutes the 'current phase,' required files, or return behavior, leaving some gaps for new users. Still adequate for familiar users.
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 baseline is 3. The description adds value by explaining the conditional requirement for the 'lgtm' parameter, which is not fully captured in the schema description alone. Other parameters are sufficiently documented in 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 tool validates required files and transitions the state machine, with a specific condition about lgtm. It effectively distinguishes this phase-advancement tool from its many siblings (e.g., sdd_checkpoint, sdd_implement) by naming the exact action and resource.
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 want to advance a phase) but does not specify when not to use it or suggest alternatives. Given the large sibling list, explicit guidance on when to prefer this tool over others would improve clarity.
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?
The description clearly states that the tool modifies CONSTITUTION.md by appending a changelog entry and updating frontmatter. With annotations all set to false, the description adequately conveys the write behavior without destructive side effects.

Does the description explain when to use this tool, when not to, or what alternatives exist?
No explicit guidance on when to use this tool versus alternatives (e.g., sdd_write_spec). The description is purely functional, leaving the agent to infer context from the tool name and purpose.
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?
The description discloses that the tool reads SPECIFICATION.md and DESIGN.md and writes CHECKLIST.md. Annotations (readOnlyHint false) are consistent with writing behavior. The force parameter is covered in schema but not in description, but overall transparency is good.
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 core action, no redundant information. Every word serves a purpose.
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 main inputs (domain, files) and output (CHECKLIST.md). It lacks mention of prerequisites (e.g., existence of SPECIFICATION.md) or error conditions, but for a checklist generation tool with clear schema, it is largely 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?
Input schema coverage is 100% with descriptions for all 4 parameters. The description does not add additional parameter semantics beyond mentioning domains. Baseline 3 is appropriate as schema already documents parameters sufficiently.
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 tool generates a domain-specific quality checklist by analyzing SPECIFICATION.md and DESIGN.md and writes CHECKLIST.md. The verb 'generates' and resource 'quality checklist' are specific, and the tool differentiates from siblings by focusing on checklists.
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 the tool should be used to generate quality checklists, but it does not provide explicit guidance on when to use this tool versus alternatives like sdd_generate_all_docs or sdd_generate_docs. No exclusions or alternative recommendations are given.
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 are all false, and description states it creates a snapshot (mutation). It does not disclose whether overwriting occurs if a checkpoint with the same label exists, nor does it detail side effects like pipeline state changes. Adequate but not thorough.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences, front-loaded with purpose, then usage. Every word earns its place — no 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 no output schema, the description does not explain return values. It adequately covers what is captured and when to use it, but lacks details on rollback mechanism or pipeline state components. Sufficient for a simple snapshot 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 parameters are well-documented in the schema. The description only adds minimal context (e.g., label examples) beyond the schema. 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 clearly states it 'Creates a named snapshot of all spec artifacts... and the current pipeline state', using a specific verb and resource. It distinguishes from sibling tools like sdd_restore (rollback) and sdd_list_checkpoints (list).
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 before making major changes so you can rollback if needed', providing clear context for when to use. However, it does not mention when not to use or list 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, destructiveHint=false, idempotentHint=true. Description adds context that output is a drift report, consistent with annotations. No contradictions.
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?
Single sentence that is clear and to the point. No wasted words 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?
No output schema, but description mentions drift report. Additional detail about report format or contents would improve 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?
All three parameters have schema descriptions (100% coverage). Description does not add new semantic 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?
Description clearly states the tool compares specification requirements against implementation files and returns a drift report. This specific verb+resource combination distinguishes it from sibling check tools like sdd_check_access or sdd_check_ecosystem.
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?

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?
The description clearly states that the tool writes to a file (side effect) and specifies the input source (DESIGN.md). Annotations are all false, so the description adds behavioral context beyond annotations. However, it does not discuss error handling or prerequisites beyond the input file existence.
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 at two sentences, front-loading the core action and then specifying the output. Every sentence adds value with no redundancy.

Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a tool with 2 parameters (both documented in schema) and no output schema, the description adequately explains what the tool produces (structured API documentation with examples) and where it writes the output. It is sufficiently complete for an agent to use without confusion.
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 baseline is 3. The description provides no additional meaning for the parameters beyond what the schema already provides (feature_number pattern and spec_dir default).
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?

It specifies the output file pattern (docs/api-{feature}.md), which distinguishes it from sibling tools like sdd_generate_docs and sdd_generate_all_docs that generate more general documentation.
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 when to use this tool (when API documentation needs to be generated from DESIGN.md), but it does not explicitly provide guidance on when not to use it or suggest alternatives such as sdd_generate_docs for non-API documentation.
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 idempotent (idempotentHint=true), non-destructive (destructiveHint=false), and modifying (readOnlyHint=false). The description adds context that the tool uses multi-stage builds for smaller production images, which is beyond annotations. No contradictions.
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 wasted words. Front-loaded with action (Reads... generates...). Every sentence adds 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?
For a generation tool without output schema, the description covers inputs (DESIGN.md or scan results), output (Dockerfile, optionally compose), and key feature (multi-stage). Missing details like format of output or idempotency behavior, but overall adequate.
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% description coverage, explaining all four parameters. The description does not add significant meaning beyond the schema, so baseline score 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 tool reads DESIGN.md or uses sdd_scan_codebase results to detect tech stack and generates a Dockerfile (optionally docker-compose.yml). This distinguishes it from sibling generate tools like sdd_generate_devcontainer or sdd_generate_iac.
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

Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given 4 parameters, no output schema, and the complexity of PBT generation, the description covers the essential purpose, source (EARS), and output (test files with specific frameworks). It could mention where files are created or that output_dir is used, but the schema covers that; overall it is sufficiently 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?
100% schema coverage means the schema already describes each parameter. The description does not add further explanation or usage hints for parameters, so it meets the baseline without additional value.

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 describes the output (role, tool access, summary) and the role priority order, which implies it is a read-only diagnostic tool. However, it does not explicitly state that it is non-destructive or require authentication, leaving some behavioral aspects implicit.
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-loading the purpose and output, with no redundant or irrelevant information. Every word earns its place.
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 simplicity (2 optional parameters, no output schema), the description is complete: it explains what the tool returns, the role priority, and the use case. No critical information is missing.
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 both parameters thoroughly. The description adds context by explaining the overall behavior and the role priority order, but it does not provide significant additional meaning beyond the schema.

Explicitly states when not to use it: compressed files are not supported natively and provides an alternative (MarkItDown MCP integration) for full Office/PDF support. This gives clear when-to-use and when-not-to-use guidance.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior5/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnly, idempotent, and non-destructive. The description adds valuable behavioral context: it verifies hash-chain integrity, checks HMAC signatures if configured, and lists return values (chain validity, entry count, current hash, hmac info, errors). This goes beyond annotations and fully informs the agent.
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 focused sentences: core action, conditional behavior, and return values. It is front-loaded and every sentence adds necessary information 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 single parameter with full schema, rich annotations, and no output schema, the description covers the tool's action, conditions, and return details comprehensively. The agent has all needed context to call and interpret results.
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 a single well-described parameter ('spec_dir'). The description adds no additional meaning beyond the schema's description, so the 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 clearly states that the tool verifies hash-chain integrity of the Specky audit log, with additional HMAC verification when configured. This uniquely identifies its purpose among siblings, as no other sibling tool performs audit verification.
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 on when to use: to verify audit trail integrity. It explains conditional behavior (HMAC key). However, it does not explicitly exclude alternative tools or state prerequisites, leaving some implicit understanding.
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 provide readOnlyHint=true and idempotentHint=true, and the description adds that the tool reads files and reports outputs, confirming no destructive actions. It specifies the output structure (coverage percentage, uncovered requirements, traceability matrix), which goes 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?
The description is two sentences, each earning its place: the first states the input and operation, the second states the output. No fluff or repetition. It is front-loaded with the action.
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 no output schema, the description fully covers return values (coverage percentage, uncovered requirements, traceability matrix). Input parameters are well-documented in schema. The tool's moderate complexity is adequately addressed.
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 thoroughly documents all three parameters. The tool description does not add further parameter-level semantics but competently wraps the schema's information.
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 reads test results JSON and cross-references with requirement IDs, reporting coverage and traceability. It uses a specific verb ('reads' plus 'cross-references') and resource ('test results', 'SPECIFICATION.md'), which distinguishes it from sibling tools like sdd_verify_tasks or sdd_compliance_check.
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 implies usage when test results are available and requirement coverage needs checking. It does not explicitly state when not to use or mention alternatives, but the context of requiring test results JSON makes it clear. However, some guidance on prerequisites or assumptions would improve it.
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 mark it as readOnly and idempotent. Description adds key behavioral info: converts to Markdown, returns content/metadata/word count, and crucially notes that compressed Office/PDF files fail with an actionable error. No contradiction 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.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Description is well-structured with front-loaded main action and subsequent details. Every sentence adds value. Slightly long due to full format list and error advice, but efficient overall.
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 no output schema, description covers all needed context: what it does, return values (content, metadata, word count), format support nuances, and failure handling. Complete for a read-only import tool with multiple file types.
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 baseline is 3. Description adds significant meaning beyond schema: explains format support levels ('fully supported' vs. 'fail'), clarifies error behavior for compressed files, and connects raw_text and file_path usage. This justifies a 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 verb (import document), resource (document formats and raw text), and outcome (converts to Markdown for SDD processing). Distinguishes from siblings like sdd_batch_import and sdd_import_transcript by focusing on single document import and conversion.
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 context on when to use (for importing and converting documents) and notes limitations (compressed Office/PDF fail) with workarounds (install MarkItDown or convert). However, does not explicitly contrast with sibling import tools like sdd_batch_import.
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 declare readOnlyHint=true, idempotentHint=true, destructiveHint=false. The description adds valuable behavioral context: it honors include_subtasks, preserves traceability, and importantly returns routing_instructions rather than creating items directly. This goes beyond annotations without 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?
The description is concise with three sentences. The first sentence immediately states the primary functionality and output shapes, front-loading critical information. No redundant or unnecessary 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 complexity (three platforms with different structures), the description provides complete context: input source, output shapes for each platform, key parameter behavior, and return value. Since no output schema exists, the description adequately explains what the tool returns (routing_instructions).
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 explicitly noting that 'project_key' is required for Jira (even though not marked required in schema) and that 'include_subtasks' is honored. This provides necessary linkage between parameters and platform-specific 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 the tool's action (transforms TASKS.md), the specific outputs (platform-specific payloads for GitHub, Jira, Azure Boards), and distinguishes it from sibling tools (no other export tool). The verb 'transforms' and resource 'TASKS.md' are precise.
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 implicitly indicates when to use the tool (when needing to export work items to one of the listed platforms). It provides detailed output shapes, but does not explicitly exclude scenarios or mention alternatives. However, given no sibling tools perform a similar function, the guidance is clear.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
