Server Quality Checklist

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

Latest release: v2.3.1
Disambiguation5/5
Each tool targets a distinct operation: file read/write/edit/delete, command execution, directory listing, backup restore, and server info. No two tools have overlapping purposes.
Naming Consistency5/5
All tool names follow a consistent snake_case verb_noun pattern (e.g., delete_file, execute_command, server_info). No mixing of conventions.
Tool Count5/5
8 tools is well-scoped for a runtime guard. Each tool earns its place by covering essential file, command, backup, and info operations without bloat.
Completeness4/5
Covers core CRUD-like operations for files, plus command execution and backup. Minor gaps like missing move/copy or directory creation tools, but agents can work around with existing tools.
Average 3.1/5 across 8 of 8 tools scored. Lowest: 2.4/5.

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?
Without annotations, the description must disclose behavioral traits. It mentions policy checks, logging, and backup but fails to explain what these entail (e.g., permissions, automatic backups, overwrite behavior). Critical side effects are omitted.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness3/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single sentence, which is concise, but it packs multiple concepts (policy checks, logging, backup) without structuring them clearly. The core action is front-loaded, but secondary features add noise.
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 presence of an output schema (unseen) and no annotations, the description should provide more context about return value, error handling, file size limits, or how backup works. It is insufficient for a write operation with multiple parameters.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters1/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
With 0% schema description coverage, the description should explain parameters. It does not mention path, content, or ctx at all, leaving the agent uninformed about their 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 the core action 'Write full file content' and adds secondary features like policy checks, logging, and backup. It is distinct from siblings like edit_file, which does partial edits, 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 is provided on when to use this tool versus alternatives such as edit_file or delete_file. The description does not mention prerequisites, limitations, or suitable contexts.
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 fully bears the burden of behavioral disclosure. It mentions reading a text file but omits details on file type, size limits, encoding, behavior on missing files, or error handling, leaving significant gaps.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness2/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is extremely short (one sentence) but suffers from under-specification rather than efficiency. It fails to include essential details that could be added without significant length, such as parameter hints or behavior notes.
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 two parameters (one required), no schema descriptions, and no annotations, the description is insufficient for an agent to correctly select and invoke the tool. It lacks parameter semantics and behavioral context.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters1/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has 0% description coverage, and the description does not explain either parameter. 'path' is only loosely implied, and 'ctx' is completely ignored. The description adds no value 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 action (read), resource (text file from workspace), and a condition (after path-policy enforcement). It distinguishes from sibling tools like write_file, delete_file, and list_directory, 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 implies a prerequisite (path-policy enforcement) but does not explicitly state when to use this tool over alternatives like list_directory or write_file. No when-not-to-use guidance is provided.
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 exist, so description must carry full behavioral burden. It mentions backups but omits details on regex, case-sensitivity, error handling, or storage location of backups.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness3/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Single sentence is concise but lacks structure for a tool with 6 parameters. Would benefit from bullet points or brief parameter descriptions.
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 6 parameters and output schema, description is insufficient. Does not clarify the use of 'edits' vs simple old/new text, or the 'ctx' parameter.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters1/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema has 0% description coverage and description adds no parameter meaning. Parameters like path, old_text, new_text, replace_all, edits, ctx are not explained.
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 it applies targeted text replacements in an existing file, with backups. This distinguishes it from siblings like write_file (creates/overwrites) and delete_file (deletes) etc.
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?
Implies use for targeted replacements but does not explicitly compare to alternatives like write_file or restore_backup. No when-not guidance 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?
The description mentions 'honoring path and depth policy,' hinting at behavioral constraints, but does not elaborate on what happens with invalid paths, policy violations, or the readonly nature. Since no annotations are provided, the description carries the full burden but only offers partial insight.
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 of 10 words, front-loaded with the core purpose. No wasted words, though it could benefit from expansion.
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?
Despite having an output schema, the description does not clarify return values, error behavior, or the depth policy. For a tool with 2 parameters and no annotations, it lacks sufficient detail for an agent to use correctly.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters1/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
With 0% schema description coverage, the description must explain parameters but fails to do so. The 'path' parameter is implicit, but 'ctx' is entirely unexplained. No additional meaning is added beyond the raw 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 action ('List directory entries') and the resource ('directory entries with metadata'). The verb 'list' distinguishes it from sibling tools like read_file or write_file, which operate on file content rather than directory structure.
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 indicate when not to use it. Siblings include other file operations, but the description does not mention contexts where list_directory is appropriate or inappropriate.
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?
No annotations are provided, so the description must carry the full burden. It indicates the tool returns identity details but does not disclose whether it requires permissions, error behavior (e.g., if server is unavailable), or performance characteristics. Adequate but could be more explicit about safety.
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: one stating the overall purpose and one listing the included items. Every word serves a purpose with no 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?
An output schema exists, so return values are documented elsewhere, but the description does not mention edge cases, error conditions, or the purpose of the undocumented parameter. For a simple informational tool, it is mostly adequate but incomplete regarding the parameter.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters1/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has one parameter 'ctx' which is optional and nullable, but the description does not mention it at all. With 0% schema description coverage, the description fails to add any meaning to this parameter, leaving an agent without guidance on what 'ctx' represents.
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 returns runtime identity details for the AIRG server, listing specific items like build id, active workspace root, and resolved base directory. This is a specific verb+resource combination that is distinct from sibling tools like file operations or restore_backup.
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 is provided on when to use this tool versus alternatives. As a diagnostic tool, it could be used for configuration validation, but the description does not mention context, 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?
With no annotations provided, the description effectively discloses key behavioral traits: safety checks like AIRG policy, network containment, command-tier policy, Script Sentinel continuity checks, and confirmation gates. However, it does not mention the mutability (destructive potential) or the output format (though output schema exists).
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, with the purpose stated first. Every sentence adds value (purpose + safety context), and there is no redundant or filler content.
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 3 parameters, no parameter descriptions in schema or description, and an output schema that is not mentioned, the description fails to provide a complete picture. It covers safety checks but omits critical param semantics and output expectations.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters1/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, and the description adds no information about any of the three parameters (command, retry_count, ctx). An agent cannot understand what 'retry_count' or 'ctx' mean or how to use them, which is a severe gap.
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 'Execute a shell command', which is a specific verb and resource. It distinguishes from sibling tools (file operations and server_info) by being the only command execution tool.
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 mentions 'after full AIRG policy and approval checks' but provides no explicit guidance on when to use this tool versus alternatives (e.g., when not to use it or what prerequisites are needed). No sibling tools compete directly, but the description could clarify scenarios where command execution is inappropriate.
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?
Description adds context about policy checks and optional backup beyond the name, but lacks details on permissions, irreversibility, or error handling. Without annotations, more behavioral disclosure would be helpful.
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?
Single sentence, front-loaded with key information. Not verbose, but could incorporate more details without being wordy.
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?
Description covers primary purpose and a safety feature (backup), but lacks return value, error cases, and interaction with siblings. Given the complexity of deletion, more completeness would aid agent selection.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters2/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
With 0% schema description coverage, the description should explain parameters. It implies 'path' is the file to delete but does not describe 'ctx' or any format constraints. The description adds minimal value over 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 verb 'delete', resource 'a single file', and additional context 'after policy checks and optional pre-delete backup'. This distinguishes it from siblings like read_file or restore_backup.
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?
Description implies tool is for deletion with safety features but does not explicitly state when to use versus alternatives like write_file or restore_backup. No exclusions or when-not guidance.
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 full burden. It discloses support for dry-run planning and token-gated apply mode, but does not mention other behaviors such as file overwrite policy, permission requirements, or error handling. This is insufficient for a restore operation.
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 core purpose and adding key behavioral notes. Every word 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?
The tool has 4 parameters and an output schema. The description covers dry-run and token modes, which are critical, but lacks details on backup_location format, context object usage, and outcome (e.g., overwrite behavior). For a restore tool, more context is needed to avoid user error.
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 0%, so the description must compensate. It adds meaning for 'dry_run' (planning mode) and 'restore_token' (gated apply), but 'backup_location' is only vaguely described as 'recorded AIRG backup manifest' and 'ctx' is not mentioned. Coverage is partial.
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 'Restore files from a recorded AIRG backup manifest,' specifying a precise verb and resource. Sibling tools are file operations unrelated to backup, so this tool is well-distinguished.
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 dry-run and token-gated modes, implying when to use them, but does not explicitly state when not to use the tool, prerequisites (e.g., existence of manifest), or alternatives. Since no sibling backup tools exist, the lack of alternatives is acceptable, but the guidance is still minimal.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
