Server Quality Checklist
Latest release: v0.2.0
- Disambiguation5/5
Each tool targets a distinct operation: generating, reviewing, submitting, canceling, and querying patches. The get_patch_job and get_patch_result are clearly differentiated by status vs. result.
Naming Consistency5/5All tools follow a consistent verb_noun pattern in snake_case (e.g., cancel_patch_job, get_patch_result). No mixed conventions or vague verbs.
Tool Count5/57 tools is well-scoped for a patch generation and management server. Each tool serves a clear purpose without redundancy or excessive granularity.
Completeness4/5The set covers the full lifecycle of patch jobs (generate, review, submit, cancel, monitor, retrieve). Minor gaps exist, such as a tool to list all jobs or delete old results, but core workflows are complete.
Average 3/5 across 7 of 7 tools scored. Lowest: 2.4/5.

How to sync the server with GitHub?
Servers are automatically synced at least once per day, but you can also sync manually at any time to instantly update the server profile.
To manually sync the server, click the "Sync Server" button in the MCP server admin interface.
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?
No annotations provided. The term 'cooperative cancellation' hints at non-forceful termination but lacks details on side effects, idempotency, or what happens if already completed.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness3/5Is the description appropriately sized, front-loaded, and free of redundancy?
Extremely concise (one phrase) but at the cost of completeness; boundary of appropriate conciseness.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no output schema, one param, and related siblings, the description is insufficient. Lacks mention of expected behavior (e.g., job may not stop immediately), potential failures, or post-cancellation status checks.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters1/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema has one parameter 'job_id' with no description; description coverage is 0%. The description does not explain how to obtain job_id or its format.
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 states the verb 'cancel' and the resource 'background streamed job', which is clear and specific. However, it doesn't differentiate from sibling tools like 'get_patch_job' or 'submit_patch_job'.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5Does 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; missing context like 'use this to stop a running job when it is no longer needed'.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
- Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so description must cover behavior. Mentions that it returns either a persisted result or non-terminal status, but doesn't elaborate on what triggers each, side effects, or idempotency. Insufficient for a mutation-adjacent tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5Is the description appropriately sized, front-loaded, and free of redundancy?
Single sentence, no fluff. Front-loaded with action. However, it could add useful detail without becoming lengthy.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
With no output schema, description should cover return value details (e.g., format of status, possible values). It mentions 'non-terminal status' but doesn't define it. Lacks completeness for a tool with simple interface.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters2/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Single parameter job_id with 0% schema description coverage. Description does not explain what job_id is or its format. Agent must infer from name alone.
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?
Description clearly states it returns a 'persisted validated result' or 'current non-terminal status', which distinguishes it from siblings like get_patch_job (which may return the job itself) and submit_patch_job. The verb 'return' is specific.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5Does the description explain when to use this tool, when not to, or what alternatives exist?
No explicit guidance on when to use this versus alternatives like get_patch_job. Context suggests it's for checking result/status after submission, but not stated.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
- Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries full burden. It mentions the tool returns a corrected diff or empty patch, but lacks details on side effects, rejection handling, or system state changes. The term 'untrusted' hints at security but is insufficient.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, front-loaded sentence with no wasted words. It could benefit from structuring, but remains concise and clear.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness1/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given 7 parameters (4 required), no output schema, and no annotations, the description fails to provide essential context. Key terms like task, file_context, and allowed_paths are left undefined, and output format is vague.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters1/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, and the description adds no parameter-level information. It only mentions 'candidate patch' implicitly, but none of the other 6 parameters (e.g., task, file_context, allowed_paths) are explained.
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 verb 'review' and the resource 'untrusted candidate patch', with specific outcomes of returning a corrected replacement diff or an empty patch. This distinguishes it from siblings like generate_patch (create) and submit_patch_job (submit).
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5Does the description explain when to use this tool, when not to, or what alternatives exist?
No explicit when-to-use or when-not-to-use guidance is provided. The description implies use for security review of patches, but does not mention alternatives like generate_patch or submit_patch_job for different stages.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
- Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are present, so the description must bear the full burden. It mentions the job is 'long-running' and 'streamed' and returns an ID immediately, but does not disclose potential side effects, required permissions, rate limits, or what happens on failure. Critical behavioral traits are missing.
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, front-loaded sentence of 18 words that efficiently conveys the core purpose and key characteristics. Every word adds value, and there is no extraneous information.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Despite a complex 7-parameter schema and no output schema, the description only covers high-level functionality. It omits explanations of parameter roles, return structure beyond a job ID, and any behavioral caveats. The agent lacks sufficient context to use the tool effectively.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters1/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has 0% description coverage for its 7 parameters, and the tool description provides no explanation of what parameters like 'task', 'file_context', or 'allowed_paths' mean. The agent cannot determine parameter semantics from the description alone, severely hindering correct invocation.
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 specifies the action ('submit') and resource ('patch job'), adds behavioral details ('long-running', 'streamed', 'returns local job ID immediately'), and is easily distinguishable from sibling tools like get_patch_job or cancel_patch_job.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5Does the description explain when to use this tool, when not to, or what alternatives exist?
Description gives no explicit guidance on when to use this tool versus alternatives. Sibling tools are listed but no comparisons or exclusion criteria are provided. The agent is left to infer usage context from the tool name and description alone.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
- Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the burden. It discloses that no DeepSeek call is made, but says nothing about potential side effects, cost, or what 'capabilities' entails. The behavioral disclosure is minimal.
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 sentence of 7 words is highly concise and front-loaded. No wasted text; every word adds value.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Despite no parameters or output schema, the description lacks context about what 'capabilities' are and how this tool fits into the patch workflow suggested by siblings. It is incomplete for an agent to decide when to invoke it.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
There are no parameters, so the schema is trivially covered. The description adds context beyond the schema by specifying the resource and the fact that no external call is made, justifying a baseline of 4.
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 'local worker capabilities' and distinguishes it by noting it does so without calling DeepSeek. This is a clear verb-resource pair that implies a read operation, though sibling differentiation is implicit.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5Does 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 implies it is for getting capabilities locally, but does not mention when to prefer it or mention any alternatives among siblings.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
- Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must disclose behavioral traits. It only mentions 'persisted status and aggregate stream progress' without detailing side effects, permissions, or rate limits.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5Is the description appropriately sized, front-loaded, and free of redundancy?
Single sentence with no fluff, but would benefit from additional context. Efficient but not maximally informative.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
No output schema exists and the description omits details about return format, status values, or progress interpretation. Inadequate for practical use.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters2/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 0% and the description does not explain the job_id parameter beyond its existence. No format, source, or constraints are provided.
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 the verb 'return' and resources 'persisted status and aggregate stream progress for a background job'. It distinguishes from sibling tools like cancel_patch_job or get_patch_result.
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 checking job status, but provides no explicit guidance on when to use this versus alternatives like get_patch_result or submit_patch_job.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
- Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden. It explicitly states the tool never edits the repository, which is the key behavioral trait. Additional clarity about validation or side effects would improve this, but the main constraint is clearly disclosed.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is 5 sentences long, front-loading the core purpose and then adding usage guidelines. It is mostly concise, though some repetition could be trimmed. The structure is logical.
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?
Given the tool has 6 parameters and no output schema or annotations, the description provides a good overview but lacks detail on task and constraints parameters, output format, or error behavior. It is adequate but not exhaustive.
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 0%, so the description must add meaning. It explains file_context should include repository-relative paths, allowed_paths defines which files the patch can modify, and provides context for test_failures. However, task and constraints parameters are not described, leaving gaps.
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 generates a validated candidate unified diff and explicitly notes it never edits the repository. This specific verb-resource combination distinguishes it from siblings like submit_patch_job and review_patch.
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 advises using deepseek-v4-pro for complex work and deepseek-v4-flash for routine changes, and specifies that on a repair round the agent should include current file contents and test/build failures. While it provides context for when to use different models, it does not explicitly exclude alternatives.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
