Server Quality Checklist
Latest release: v1.0.0
- Disambiguation5/5
Each tool has a distinct and well-defined purpose with no overlap. For example, godot_analyze_scene and godot_analyze_script target different file types and antipatterns, while godot_run_project and godot_run_tests handle project execution versus testing separately. The descriptions clearly differentiate the tools, making misselection unlikely.
Naming Consistency5/5All tools follow a consistent 'godot_verb_noun' naming pattern, using snake_case throughout. This predictable structure (e.g., godot_analyze_scene, godot_run_tests) enhances readability and makes it easy for agents to infer tool functions from their names.
Tool Count5/5With 8 tools, the server is well-scoped for Godot project development and analysis. Each tool serves a specific, non-trivial function (e.g., analysis, diagnostics, execution, testing), and none feel redundant or missing, fitting the domain appropriately without being overwhelming.
Completeness4/5The toolset covers core workflows for Godot development, including analysis, diagnostics, project management, execution, testing, and documentation. Minor gaps exist, such as no direct tools for editing or creating scenes/scripts, but agents can work around this by using analysis tools to inform manual changes, and the surface is otherwise comprehensive.
Average 4.1/5 across 8 of 8 tools scored.

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
- Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description adds behavioral context beyond annotations by explaining progressive disclosure (summary by default, full on request) and listing the data fields returned. Annotations already indicate read-only and idempotent, so the description enriches but does not contradict.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5Is the description appropriately sized, front-loaded, and free of redundancy?
Two concise sentences: first specifies the tool's output, second explains the progressive disclosure. No fluff, and the key information is front-loaded.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool has only one optional parameter and no output schema, the description covers purpose, behavior, and data scope adequately. It could mention the return format (e.g., JSON), but the listed items and progressive disclosure provide sufficient context.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage for the single parameter 'detail' is 100%, with a clear description and enum. The description reinforces that 'summary' is default and 'full' provides more detail, but adds no new semantics beyond the schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool returns a project structure overview listing specific components (name, version, scenes, scripts, etc.). While it is specific and uses a verb, it does not explicitly differentiate from sibling tools like godot_analyze_scene or godot_get_diagnostics, though the purpose is distinct.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies usage for obtaining project info, but it does not provide explicit guidance on when to use this tool versus alternatives, nor does it mention any prerequisites or exclusions.
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?
Describes capturing stdout/stderr with timestamps, adding value beyond annotations. However, it doesn't address side effects like starting multiple instances or security implications.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5Is the description appropriately sized, front-loaded, and free of redundancy?
A single, front-loaded sentence covering the core actions and output capture without unnecessary words.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The description covers the basic functionality but omits details about tool behavior under edge cases (e.g., stopping a non-running project, output format) and no output schema.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, so the description adds no significant meaning beyond the schema. The parameters are self-explanatory from the schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool launches, stops, or gets debug output from a running Godot project, which distinguishes it from sibling tools like analysis or diagnostics.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies usage for project lifecycle management but does not explicitly state when to use this tool versus alternatives or any prerequisites.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
- Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already indicate readOnly and idempotent behavior. The description adds value by enumerating the exact checks performed, going beyond what annotations provide. No contradictions are present.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single concise sentence that front-loads the purpose and lists all pitfalls. Every part is informative with no wasted words.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The description covers what the tool does but does not mention the output format or return value. Given no output schema, this is a gap that could affect an agent's understanding of the result.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The single parameter 'path' is well-described in the input schema (coverage 100%). The description does not add additional semantics beyond the schema, so a baseline score of 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool analyzes GDScript files for exactly 10 specified pitfalls, using a specific verb ('Analyse') and resource (GDScript files). It distinguishes itself from sibling tools like godot_analyze_scene by focusing on script-level issues.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5Does the description explain when to use this tool, when not to, or what alternatives exist?
The description lists all 10 pitfalls, giving clear context on when to use the tool (e.g., when suspecting Godot 3→4 API misuse or other listed issues). It does not explicitly mention when not to use it or compare with alternatives, but the specific scope provides strong guidance.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
- Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already indicate read-only and idempotent behavior. The description adds value by specifying what analysis it performs (antipatterns, format errors). It does not mention authentication or side effects, but these are covered by annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences with zero wasted words. The purpose is front-loaded ('Parse .tscn... and return structured analysis') followed by specific detections.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no output schema, the description could mention return structure (e.g., 'returns JSON with issues found'). However, it adequately covers behavior for a simple read-only analysis tool.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% and the schema description for 'path' is clear ('Path to .tscn or .tres file...'). The tool description adds no further parameter semantics beyond restating file types, so baseline 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool parses .tscn/.tres files and returns structured analysis, detecting specific antipatterns and errors. It distinctly differs from sibling tools like godot_analyze_script (which targets scripts) and godot_get_diagnostics (likely broader diagnostics).
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies usage for analyzing scene/resource files, but does not explicitly state when not to use it or compare to alternatives. However, the sibling names provide clear differentiation, so the context is directionally sufficient.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
- Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations indicate read-only and idempotent. Description adds the runtime requirement of having the editor open and project loaded, which is beyond annotation scope. 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.
Conciseness5/5Is the description appropriately sized, front-loaded, and free of redundancy?
Two concise sentences, no unnecessary words. Front-loaded with the core action and critical requirement.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Describes what the tool does and a key prerequisite. Lacks explanation of return value format (e.g., list of diagnostics), but given the name and context, it is reasonably complete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Input schema has 100% coverage with good descriptions. Description does not add extra meaning beyond schema; it mentions 'errors, warnings' but not parameter-specific. Baseline 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
Description clearly states verb 'get', resource 'LSP diagnostics', and context 'from Godot's built-in language server'. It distinguishes from siblings like godot_analyze_scene by specifying diagnostics retrieval.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5Does the description explain when to use this tool, when not to, or what alternatives exist?
Provides a critical prerequisite ('Requires Godot editor to be running with the project open'), giving clear when-to-use guidance. Does not explicitly compare to alternatives, but the prerequisite is essential and well-stated.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
- Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already indicate read-only and idempotent behavior. The description adds valuable behavioral context (display server requirement and return format) beyond annotations. 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.
Conciseness5/5Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences with no redundant information. Front-loaded with the core action and return type, followed by a critical usage note. Every sentence serves a purpose.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given a simple tool with one optional parameter, the description covers the essential behavior, return format, and key constraint. No output schema exists, but the description explains the output format. Minor gap: doesn't mention potential errors or performance impacts.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so the schema sufficiently explains the optional 'scene' parameter. The description doesn't add extra meaning beyond 'If omitted, captures main scene', so baseline 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool's verb (Capture), resource (viewport screenshot), and return format (base64-encoded PNG). It distinguishes from sibling analysis tools by specifying 'screenshot' functionality.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5Does the description explain when to use this tool, when not to, or what alternatives exist?
The description includes an important precondition: 'Requires a display server (not headless mode)', which guides when not to use. However, it doesn't explicitly compare to alternatives or state when to choose this tool over siblings.
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 headless execution, auto-detection of framework, and return of structured pass/fail counts with failure details. These go beyond the annotations (idempotentHint=true). No contradictions with annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5Is the description appropriately sized, front-loaded, and free of redundancy?
Two concise sentences front-load the action 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.
Completeness5/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the lack of an output schema, the description sufficiently explains the return format (counts and failure details). All parameters are documented in schema. The tool fits well among siblings without missing context.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100% with clear parameter descriptions. The tool description adds the auto-detection behavior but does not enhance parameter 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.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool runs GUT or GdUnit4 tests headlessly and returns structured results. It auto-detects the framework, which is a specific differentiator from siblings like godot_run_project. The verb 'Run' and resource 'tests' 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 Guidelines4/5Does the description explain when to use this tool, when not to, or what alternatives exist?
The description makes it clear this tool is for running tests, not for other operations like running the project or analyzing scenes. However, it does not explicitly mention when not to use it or point to alternatives, which would earn a 5.
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 read-only and idempotent. The description adds valuable behavioral context: automatic detection of Godot 3 queries and suggestion of Godot 4 equivalents, plus a warning about AI-generated bugs.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences, no fluff. First sentence immediately states purpose and capabilities. Second sentence adds crucial warning. Perfectly concise.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no output schema, the description mentions return types (overviews, method details, fuzzy results) but does not specify structure (e.g., Markdown, JSON). Sufficient for most agents.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema covers 100% of the single parameter. Description does not add parameter details beyond what schema provides, though it implies outputs related to query.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states it searches Godot 4.x API documentation and distinguishes itself from sibling tools (analysis, run, etc.) by focusing on documentation search.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5Does the description explain when to use this tool, when not to, or what alternatives exist?
It explains what to search for (classes, methods, terms) and warns about Godot 3 queries, but does not explicitly state when not to use it or name alternatives among siblings.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
