Server Quality Checklist

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

Latest release: v0.1.0
Disambiguation5/5
Each tool has a clearly distinct purpose with detailed descriptions. Even closely related tools like list_anomalies and get_open_anomalies differ in scope and are well explained, preventing confusion.
Naming Consistency5/5
Tool names consistently follow a verb_noun pattern (e.g., create_agent_identity, list_clusters). Subsystem prefixes like registry_, helm_, and slurm_ are used uniformly, maintaining a predictable structure.
Tool Count2/5
With 74 tools, the server covers a vast scope. While each tool is justified, the count far exceeds typical well-scoped ranges (3-15 tools) and falls into the 'too many' category, making navigation challenging.
Completeness3/5
The tool surface is broad but has notable gaps: missing delete_secret, cancel_job (non-Slurm), and create/update/delete for pipelines. Core workflows are covered, but lifecycle operations for some resources are incomplete.
Average 4.3/5 across 74 of 74 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?
No annotations provided; description does not disclose behavior beyond listing (e.g., idempotency, authentication needs, 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.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Description is brief with a clear first sentence and structured Args list, but some lines are slightly wordy.
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; description omits return value (list of tags) and does not fully specify parameter dependencies per registry type.
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?
Description adds some meaning to parameters (e.g., registry_type backends, image format examples) but not all parameters are adequately explained; 0% schema coverage increases burden.
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 'List all tags for a specific image in a container registry.' with specific verb and resource, easily distinguishable from siblings like registry_list_repos.
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., registry_list_repos, registry_check_image) or prerequisites.
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, and the description does not disclose behavioral traits such as whether the tool is read-only, authorization requirements, or error handling. It only implies a safe read operation without explicit confirmation.
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 very concise, with two sentences and a parameter listing. No unnecessary 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?
Given the low complexity (one parameter, no output schema), the description covers the basic purpose but lacks return format details and distinction from similar tools like get_agent_usage or get_budget.
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 adds minimal value by restating 'agent_id: The agent identifier.' No further details on format, source, or constraints are provided.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool returns the inference budget for a specific agent, listing specific fields (monthly limit, current spend, enforcement action). It distinguishes itself from siblings like get_agent_usage and get_budget by focusing on budget details.
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 (e.g., get_budget, get_agent_usage). The description does not provide context for appropriate usage or prerequisites.
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 fully cover behavioral traits. It does not disclose whether authentication is required, whether the operation is read-only, rate limits, pagination behavior, or side effects. The 'limit' parameter suggests pagination but is not explained.
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 front-loaded with the main purpose and uses a structured list for parameters. While slightly verbose with the 'Args:' header, each line is concise. It earns a 4 for being well-organized and efficient.
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 8 parameters, 0% schema coverage, and no output schema or annotations, the description is incomplete. It explains parameters but does not describe the return value (what is listed?), error conditions, prerequisites, or authentication flow. The 'gateway_id' parameter hints at a site context but is not elaborated.
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 0%, but the description includes a clear explanation for each parameter (e.g., 'Registry backend — "harbor", "ecr", or "gar".'). This adds significant meaning beyond the schema's type information. A score of 4 is warranted because all parameters are briefly described.
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 'List repositories in a container registry (Harbor, ECR, or Google Artifact Registry).' This is a specific verb+resource combination, and it distinguishes from sibling tools like registry_list_tags and registry_check_image which have different purposes.
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 explicit guidance on when to use this tool versus alternatives. The description does not mention when-not-to-use or provide comparison with sibling tools. Usage is only implied by the list of parameters.
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 provided. The description implies a read-only operation by returning cluster information, but it does not explicitly state safety, idempotency, or side effects. Adequate but could be more transparent.
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 a clear summary line and a structured Args section. Every sentence adds information, 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?
No output schema exists, and the description only broadly states what is returned (nodes, GPU resources, memory, state). It lacks specifics about the output format or additional fields, which would help an agent parse results.
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 0%, but the description explains each parameter: 'host' overrides an environment variable, 'partition' filters output, 'gateway_id' identifies the site. This adds value beyond the schema's minimal titles.
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 'Get Slurm cluster information: partitions, node states, and GPU availability.' This is a specific verb+resource combination that distinguishes it from sibling tools like slurm_list_jobs and slurm_submit_job.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
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 (e.g., slurm_get_job_status, slurm_list_jobs). The description only explains parameters, not use cases or exclusions.
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?
With no annotations, the description must fully disclose behavior. It mentions that deny overrides allow, a key behavioral trait. However, it does not specify whether the tool is idempotent, replaces or merges rules, or if it requires specific permissions. The name-update vs description-create mismatch further undermines transparency.
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 well-structured with a brief overview, examples, and a clear argument list. It is concise without unnecessary details, though the name-description mismatch is a minor structural flaw.
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 the lack of output schema and annotations, the description adequately explains functionality and parameters. However, it misses return values, error handling, and behavioral details like overwrite behavior, leaving gaps for an agent relying solely on it.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters5/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has 0% description coverage, so the description fully compensates. It explains each parameter (agent_id_pattern, allowed_models, denied_models) with clear formats and examples, adding significant meaning beyond the schema.
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 creates an agent model access rule and controls which LLM models an agent can use. It is specific about the resource and action, though the name 'update' contradicts 'create', causing minor confusion.
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 provides examples illustrating when to use the tool, such as allowing Llama models or blocking GPT-4o. However, it lacks explicit guidance on when not to use it or alternatives, leaving the agent to infer usage context.
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 key behaviors: encryption at rest, value never returned, audit logging, and overwrite behavior. Given no annotations, this coverage is thorough, though it omits potential permission requirements or side effects beyond audit logging.
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 a clear opening sentence, behavioral notes, and a structured Args section. Every sentence adds value, and there is no redundancy or irrelevant 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?
Given the tool's simplicity (3 parameters, no output schema), the description covers the purpose, behavior, parameter semantics, and side effects adequately. It does not explain the return value (likely success/failure), but this is minor. The description is sufficient for an agent to understand the tool's function.
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?
With 0% schema coverage, the description must compensate. It adds meaning by explaining each parameter: name as reference, value as encrypted and not logged/returned, description as optional. However, it lacks examples, format constraints, or default values, leaving room for ambiguity.
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's purpose: 'Store an encrypted secret in the VibOps vault.' The verb 'store' and resource 'encrypted secret' are specific. While there is no direct sibling for creating secrets, it distinguishes itself from other create tools like create_agent_identity by focusing on secrets.
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 overwrite behavior ('If a secret with the same name already exists, it is overwritten.'), which implies usage when creating or updating. However, it does not provide explicit guidance on when to use this tool versus alternatives, such as when to update vs. create anew, or any prerequisites.
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 the description must disclose behavioral traits. It describes the output but omits details about permissions, rate limits, side effects, or what happens with no data. Read-only nature is implied but not stated.
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 concise sentences plus a bullet for the parameter, front-loaded with the main purpose, and free of unnecessary 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?
Given the simple input schema (single optional parameter, no output schema, no annotations), the description covers the tool's purpose, output structure, and parameter meaning adequately, though missing behavioral details.
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?
Despite a reported schema description coverage of 0%, the description explicitly explains the 'hours' parameter (look-back window in hours with default 168 = 7 days), adding context beyond the schema's type and 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?
The description clearly states the tool returns Mean Time To Resolve (MTTR) for GPU alerts, broken down by cluster and severity, which is a specific metric distinct from sibling tools like get_gpu_metrics or resolve_anomaly.
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 provides a use case ('assess operational reliability and incident response speed over time') but does not explicitly state when to use this tool over alternatives 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.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so description carries full burden. It mentions default log path and host parameter overriding env var, but does not disclose error handling, authentication needs, or what happens if job not found.
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?
Clear structure with a main paragraph and an Args block. Slightly verbose but well-organized and easy to read.
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 output schema and does not describe return format or error scenarios. For a tool with 5 parameters and no annotations, the description is not fully complete.
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 description coverage is 0%, but the description includes a docstring that explains all 5 parameters (job_id, host, log_path, lines, gateway_id), adding meaning beyond the schema's type and 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?
Clearly states it tails the stdout log file of a Slurm job to monitor training progress, with a clear verb and resource. Distinguishes from sibling tools like slurm_get_job_status and slurm_list_jobs.
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 usage by describing the action (reading output of a Slurm job), but lacks explicit guidance on when to use versus alternatives, or when not to use.
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 provided, so description carries burden. Discloses return types (kubectl stdout, Helm output, error message) but lacks info on auth, rate limits, or error handling for missing jobs.
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?
Five sentences, front-loaded with purpose, then usage, then parameter detail. No redundant or missing information. Efficiently structured.
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, description adequately describes return values (details, result including stdout, Helm output, error message). Parameter is fully covered. Could mention response format but sufficient for a simple get operation.
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 0%, but description adds meaning by specifying job_id accepts 'Full UUID or short ID (first 8 characters)', which is helpful beyond the schema's plain string type.
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 it returns details and results of a specific operation. Differentiates from list_jobs and other get_* siblings by emphasizing result output, but does not explicitly distinguish from get_job_evaluations or get_job_metrics.
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 'Call this to check whether a previously submitted action succeeded or failed, and to retrieve its output.' Provides clear when-to-use but does not mention alternatives 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.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden. It discloses it is a write operation recorded in audit logs, and for 'release_name' it notes it is created if not existing, implying idempotency. However, it does not describe other behavioral aspects such as whether the operation is reversible, if it triggers a rollout, or if it requires any specific permissions. The description provides functional details but lacks deeper behavioral context.
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 concise: a one-sentence purpose, one-sentence alternative, one-sentence behavioral note, then a structured argument list. It front-loads key information and avoids redundancy. However, the argument list could be slightly more compact, and some definitions are a bit verbose (e.g., gateway_id explanation). Overall, it is well-structured and efficient.
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?
The tool has 6 parameters, no output schema, and is a Helm upgrade operation. The description explains inputs well but fails to describe the output or return value. Since no output schema exists, the agent needs to know what to expect (e.g., release status, success message). The description also omits potential side effects beyond audit logging (e.g., rollback behavior). This gap in completeness is significant for a complex operation.
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 description coverage is 0%, so the description must compensate. It provides clear, meaningful definitions for all 6 parameters, including examples for 'chart' (e.g., bitnami/nginx), default for 'namespace', and usage guidance for 'gateway_id' (when to omit/provide). This adds significant value beyond the schema titles. Missing type specification for 'values' (though implied) and no format for 'cluster_name' keeps it from a 5.
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 runs 'helm upgrade --install for a chart on a cluster.' It specifies the verb (run helm upgrade --install) and resource (chart on a cluster). It also distinguishes from sibling 'deploy_model' by noting that for deploying standard AI models, that tool should be used instead. This makes the purpose specific and distinct.
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 explicitly says 'Use this for Helm chart deployments' and provides an alternative: 'For deploying standard AI models, use deploy_model instead.' It also notes it's a write operation recorded in the audit log, which guides usage context. However, it does not mention exclusions like when not to use it beyond the AI model case, or prerequisites like needing cluster access, which would elevate to a 5.
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 the description must compensate. It mentions limit default/max but omits pagination, ordering, and output structure. For a listing tool, this 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.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is concise and well-structured, front-loading the purpose and including only essential information in a few sentences.
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 output schema or description of return values. No mention of pagination or sorting, which is important for a list tool, but the single parameter is well-covered.
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?
With 0% schema coverage, the description adds value by explaining the limit parameter's purpose and maximum, going beyond the schema's type and 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?
The description clearly states the verb 'List' and the resource 'pipelines', and distinguishes pipelines from single jobs with a concrete example.
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?
It explains the distinction from jobs and directs to trigger_pipeline for triggering, providing good context for when to use this tool, though it does not explicitly exclude alternatives like list_jobs.
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 provided, so description carries full burden. States 'Write operation — recorded in the audit log' and mentions default signal SIGTERM with SIGKILL option. However, does not disclose effects on job dependencies, synchronous nature, or error conditions.
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?
Extremely concise: one sentence for purpose, one for audit note, then bullet-style args. No wasted words, front-loaded with key info.
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?
Missing output/return value description (likely success/error). No mention of permissions or idempotency. Parameter coverage is good but behavioral gaps remain for a cancellation operation.
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 description coverage is 0%, but description's 'Args' section adds meaning: explains job_id, host (overrides env var), signal (default, usage for immediate termination), and gateway_id. Provides context beyond schema definitions.
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?
Clear verb 'Cancel', specific resource 'Slurm job', and identifies as a write operation recorded in audit log. Distinguishes from sibling read tools like slurm_get_job_status and submission 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?
No explicit guidance on when to use vs alternatives. Mentions it's a write operation but lacks preconditions or cases when cancellation is inappropriate. Implied usage by context, but no 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?
With no annotations, the description bears full burden. It lists returned fields and parameters but omits details like default filtering behavior (e.g., what 'running and pending' means when state filter allows other values), pagination, auth needs, or whether jobs are scoped to the caller. Partial but not exhaustive.
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 for purpose and return fields, followed by a clear list of parameters. Front-loaded with the main action, no wasted words, and well-structured for quick scanning.
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 5 parameters and no output schema, the description covers purpose, return fields, and all parameters. It lacks default behavior if filters are omitted and does not mention pagination or limits, but is generally adequate for a list tool with good parameter descriptions.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters5/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the description fully compensates. Each parameter is described with its purpose and options (e.g., 'Filter by job state — RUNNING, PENDING, FAILED, COMPLETED'), providing essential context missing from 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 lists Slurm jobs, specifies the verb 'list', the resource 'Slurm jobs', and even enumerates the returned fields (job ID, name, state, etc.), differentiating it from siblings like 'get_job' or 'list_jobs' by focusing on Slurm-specific jobs.
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 vs alternatives such as 'list_jobs' or 'slurm_get_job_status'. While the Slurm-specific name hints at context, there is no mention of when not to use it or any exclusions.
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 provided, so the description carries the full burden. It discloses the type of analysis and output (cost estimates, remediation actions), but does not mention whether it runs a fresh query or uses cached data, nor any potential side effects or access constraints.
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 clearly structured: first sentence states the high-level purpose, second lists identification criteria, third describes output. Every sentence 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 zero parameters and no output schema, the description sufficiently explains what the tool returns and the criteria used. It also includes temporal specificity (24h, 7 days), making it mostly complete. Could ideally mention if it aggregates data across clusters or users, but not a major gap.
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?
There are zero parameters, so the tool relies entirely on the description. The description adds substantial meaning by detailing what findings are returned and the nature of the output (cost estimates and remediation actions), compensating for the lack of parameters.
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 GPU waste analysis of idle resources, specifying three identification criteria (GPU nodes with <10% utilization, deployments with zero jobs, over-provisioned replicas). This distinguishes it from sibling tools like get_gpu_metrics or get_spend_trend.
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?
No explicit guidance on when to use this vs alternatives, nor any exclusions or conditions. The purpose is implied but the description lacks direct recommendations for the agent.
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 provided; description reveals auto-scanner behavior but does not explicitly state read-only nature or any security/permission requirements. 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: first states purpose, second adds details. No wasted words, front-loaded, and very concise.
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?
Good coverage for a simple list tool with no output schema and no annotations. Missing details on potential implicit filters or ordering, but adequate overall.
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?
No parameters in schema; description adds meaning by explaining what each rubric contains, providing context beyond the empty schema. Baseline 4 for 0 params.

Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states 'List LLM-as-judge evaluation rubrics' with a specific verb and resource, and distinguishes from siblings by detailing what a rubric includes (criteria, scoring grid, LLM provider, auto-scanner flag).
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 usage when needing to view available rubrics, but lacks explicit guidance on when not to use or alternatives like evaluate_job or get_job_evaluations.
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 full burden. It mentions default and max limit but does not disclose behavior such as pagination, ordering, security/permissions, or whether the operation is read-only (though implied). Lacks explicit assurance of 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 short and front-loaded, starting with the core purpose. It uses a clear structure: summary, clarification, then parameter details. No unnecessary words.
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?
Covers purpose, parameter details, and links to sibling get_job. However, lacks description of return format (fields, ordering) and any prerequisites or permissions. Given no output schema, more detail on return values would improve completeness.
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?
The 'Args' section explains all three parameters with valid value lists for status and action, plus default/max for limit. Since schema coverage is 0%, the description adds significant meaning 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 verb 'List' and the resource 'VibOps operations', and distinguishes itself from sibling tool 'get_job' by specifying it retrieves full results of a specific operation. It also clarifies that VibOps jobs are not Kubernetes Jobs.
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 clear context for when to use this tool (listing recent operations) and when to use an alternative ('Use get_job to retrieve the full result of a specific operation'). Does not explicitly mention when not to use it, but the purpose is clear enough.
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 carries the full burden. It discloses the behavioral consequence of exceeding the hard cap (blocking requests with 429). However, it does not mention whether the budget change is immediate, reversible, or any required permissions. Transparency is 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?
The description is extremely concise: two introductory sentences and a bullet-like parameter list. Every sentence adds necessary information, and there is no redundancy or fluff. The structure is clean and easy to parse.
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 the return value (e.g., success confirmation) or error cases. However, for a mutation tool that sets a budget, the core functionality is well-covered. Minor gaps in output and error behavior prevent a perfect score.
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 description coverage is 0%, but the description lists all five parameters with clear meanings: agent_id (identifier), monthly_limit_usd (spend limit), soft_cap_pct (warning percentage), hard_cap_pct (block percentage), action (enforcement options). This adds significant value over the bare schema, though it could include expected formats or valid ranges.
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 purpose: 'Set or update the monthly inference budget for an agent.' It also explains the effect when the hard cap is exceeded, which adds specificity. The verb 'set or update' combined with the resource 'monthly inference budget' is precise and distinguishes it from the sibling tool 'get_agent_budget'.
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?

Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no output schema and no annotations, the description covers the essential behavior and parameter details. It lacks output format and error handling, but overall it is sufficiently complete for a simple retrieval tool.
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 0% (no parameter descriptions in schema). The description adds meaningful explanations for all three parameters: job_id, host (overrides env var), and gateway_id. This compensates well for the lack of schema descriptions.
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 retrieves status and resource usage for a specific Slurm job, distinguishing it from sibling tools like slurm_list_jobs (list jobs) or slurm_get_job_output (get output). The verb 'Get' and resource 'status and resource usage of a specific Slurm job' are clear and specific.

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 provided; description adds async behavior and status progression but lacks auth or rate limit details. Adequate for a read-only listing 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?
Concise, front-loaded with purpose, uses docstring style. 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 low complexity (1 param, no output schema), description covers async behavior, statuses, and cross-reference to get_compliance_report. Could mention output format but not necessary.
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?

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 or annotations, the description should cover return values, error scenarios, and prerequisites. It explains the workflow but does not mention what the tool returns (e.g., success message, cloned directory path) or what happens on failure (e.g., invalid URL, permission issues). Adequate for basic use but incomplete for robust agent selection.
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?
With 0% schema description coverage, the description's Args section adds essential meaning: repo_url is 'HTTPS or SSH', branch defaults to main, cluster_name triggers apply, gateway_id disambiguates.

Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description states 'Replace the organisation policy configuration' and explicitly says the full policy object must be supplied, not a partial patch. It clearly distinguishes from the sibling 'get_policy' which retrieves the current policy, and other update tools for different resources.
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 instructs to 'Retrieve the current policy with get_policy, modify the desired fields, then submit,' providing a clear workflow. It does not explicitly mention when not to use or alternatives, but the usage context is well-defined.
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?
No annotations provided, so the description carries the full burden. It describes the operation as a write action recorded in the audit log, and notes asynchronous execution. Does not mention rate limits or other side effects, but covers key behavioral traits.
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?
Description is concise with two main sentences plus an Args block. No superfluous text, every sentence adds value. Front-loaded with the core action.
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 tool triggers an async evaluation and does not return results directly; the description correctly points to get_job_evaluations for results. Given absence of output schema, this is sufficient. The description covers inputs, behavior, and post-operation steps.
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 0%, so description must compensate. It adds meaning to job_id by noting it must be a UUID of a job in 'success' or 'failed' state, and to rubric_id by referencing list_eval_rubrics. This goes beyond the bare 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 uses specific verb-resource pairing: 'Trigger an LLM-as-judge evaluation of a completed job against a rubric.' It clearly distinguishes from siblings like get_job_evaluations and list_eval_rubrics.
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 explains that the evaluation runs asynchronously with results retrievable via get_job_evaluations, and specifies required job states ('success' or 'failed'). While it doesn't explicitly state when not to use, the context is clear.
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 bears full responsibility for behavioral disclosure. While 'Return' implies a read-only operation, the description does not explicitly state that the tool is non-destructive, nor does it mention any side effects, rate limits, or permission requirements. The information about return data (call counts, timestamps) is helpful but falls short of full 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?
The description is extremely concise: three sentences covering purpose, details, and usage guidance. It front-loads the core action and includes a clear 'Args' section for the parameter. Every sentence adds value without 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 absence of an output schema, the description adequately explains what the tool returns: dependency edges with specific elements (models, connectors, sub-agents) and metadata (call counts, timestamps). For a simple retrieval tool, this is sufficient, though a brief mention of the output structure (e.g., list of edges) would increase completeness.
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?
The input schema provides no description for the required 'agent_id' parameter (0% schema description coverage). The description adds meaning by explaining that the parameter accepts 'ID or name of the agent (as registered in the tool catalogue)', which goes beyond the schema's minimal 'Agent Id' title.
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 specifies that the tool 'returns dependency edges for a single agent' and lists what it shows (models, connectors, sub-agents, call counts, timestamps). It clearly distinguishes the tool from the sibling 'get_agent_dependency_graph' by stating the latter is for the 'full organisation-wide view'.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines5/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description explicitly states, 'Use get_agent_dependency_graph for the full organisation-wide view,' providing clear guidance on when to use this tool versus the alternative. This helps the agent make an informed selection.
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?
No annotations are provided, so the description carries full burden. It discloses that the tool returns a directed graph with edges recording call_count, first_seen, and last_seen timestamps. It does not mention permissions, rate limits, or potential performance impact, but the read-only nature is implied. Overall, good transparency but could note if the graph is expensive to compute.
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: two short paragraphs, no filler. The purpose is front-loaded in the first sentence. Every sentence adds value: output definition and use case. Ideal structure for quick scanning.
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 zero-parameter tool with no output schema or annotations, the description covers the purpose, output details, and a concrete use case. It is sufficient for an agent to decide to use it. Missing a note on performance or when not to use, but overall complete given the tool's simplicity.
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?
The tool has zero parameters, and schema coverage is 100%, so baseline is 4. The description adds value by explaining the edge structure and fields beyond what the schema provides (which is empty). No further parameter semantics needed.
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 'Return the full directed dependency graph for all agents in the organisation' with specific verb and resource. It distinguishes from sibling tools by detailing edge types (agent→model, agent→connector, agent→agent) and the use case of impact analysis, which is not mentioned in any sibling tool.
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 explicitly mentions a key use case: 'impact analysis — if I replace this LLM model, which agents are affected and how frequently do they call it?' This provides clear context for when to use. However, it does not explicitly state when not to use or compare with sibling tools like get_agent_dependencies, which might offer a simpler view.
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?
No annotations are provided, so the description fully informs about behavior. It notes that the tool 'Polls the cluster via the VibOps gateway (up to 20s),' alerting the agent to potential latency and live connection. This is valuable transparency beyond a simple getter.
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: a single opening sentence defining the tool, followed by a behavior note and usage guidance. The Args section is structured cleanly. Every sentence adds value; 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?
For a tool with 2 params and no output schema, the description covers the return type (replica counts, pod health, resource usage), the polling mechanism, and param usage. It is adequate; missing details like pagination or error cases are minor given the simplicity.
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 0%, but the description adds meaningful parameter descriptions: 'cluster_name' is tied to 'list_clusters' output, and 'namespace' is explained as restricting results to a single namespace. This provides context the schema alone lacks.
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 it returns 'live Kubernetes deployment status for a cluster, including replica counts, pod health, and resource usage.' The verb 'return' and specific resource 'deployment status' make the purpose clear. It distinguishes from siblings like 'run_kubectl' and 'scale_deployment' by focusing on read-only status.
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 advises calling it 'when investigating deployment health, replica counts, or pod failures.' This provides clear context for usage. No explicit when-not or alternative tools are mentioned, but the guidance is sufficient for decision-making.
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?
No annotations provided, but the description discloses polling behavior and return fields (status, summary). Could mention error handling or authentication needs.
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?
Five concise sentences, front-loaded purpose, no wasted words. Structured with Args section.
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 explains key return fields (status, summary). Lacks mention of error responses or pagination, but sufficient for a simple poll tool.
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?
With 0% schema coverage, the description adds meaning by specifying report_id is a UUID from other tools, compensating well for the bare 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 retrieves a compliance report by ID, distinguishing it from sibling tools like generate_compliance_report and list_compliance_reports.
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?
It explicitly instructs to poll after generate_compliance_report until status=='ready', and explains the summary field. Misses explicit when-not-to-use scenarios.
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 provided, and the description does not disclose behavioral traits beyond stating it returns time-series data. It mentions the hours parameter with default and max, but lacks details on data source, update frequency, or any side effects. Adequate but not rich.
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?
Concise and well-structured: first sentence states the main action, then usage guidance, then parameter details. Every sentence adds value with minimal wordiness.
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 one parameter and no output schema, the description is quite complete. It covers what it returns, when to use, and alternatives. A minor omission is the return format of the time series, but not critical.
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?
The schema has 0% description coverage, but the description adds 'Look-back window in hours (default 24, max 168)', providing context beyond the schema's type and 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?
The description states 'Return hourly GPU utilisation time-series for the last N hours' with a specific verb (Return) and resource (GPU utilisation time-series). It clearly distinguishes from siblings by naming alternatives for cost and workload breakdown.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines5/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
Explicitly says when to use ('assess whether GPUs are idle, saturated, or trending toward failure') and provides alternatives: 'For cost implications... use get_cost_estimate. For a breakdown... use get_workload_breakdown.'
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 is a write operation recorded in the audit log and that it removes all Kubernetes resources created by the release. With no annotations provided, this adds valuable behavioral context, though it does not cover error cases or partial failures.
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 two introductory sentences, a note on audit logging, and a bulleted list of arguments. Every sentence adds value with no 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?
For a destructive Helm operation with four parameters and no output schema, the description adequately covers purpose, behavioral impact, audit logging, and parameter semantics. No critical gaps remain.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters5/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, but the description fully explains each parameter in the Args section, including the optional gateway_id and its disambiguation rule. This adds significant meaning beyond the schema's property names and defaults.
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 'Uninstall a Helm release from a cluster.' It uses a specific verb (uninstall) and resource (Helm release), and distinguishes from sibling tools like helm_upgrade which performs upgrades.
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 does not provide explicit guidance on when to use this tool versus alternatives (e.g., helm_upgrade). Usage is implied through the description of the operation, but no direct comparisons or exclusions 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?
No annotations provided, so description carries full burden. It states the tool lists clusters with a GPU summary, implying a read operation. However, it doesn't disclose potential costs, pagination, or what exactly 'GPU utilisation summary' entails. Lacks depth in behavioral traits beyond the basic action.
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: first states purpose, second provides usage guidance. Front-loaded, no redundant words. Efficient and well-structured.
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 parameters, no output schema, and no annotations, the description covers core functionality and usage boundaries. It mentions the output includes a GPU utilisation summary, which is valuable. Could be more complete by describing output structure, but it's sufficient for a simple list tool.
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?
Tool has zero parameters, so schema coverage is 100%. Baseline score of 4 applies. Description adds no parameter-specific info, but none is needed.
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 lists all clusters registered in VibOps along with GPU utilisation summary. It distinguishes from sibling tool list_kubectl_contexts by specifying it's for registered clusters, not raw kubeconfig contexts.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines5/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
Explicitly tells the agent to start with this tool for available clusters or fleet status, and directs to list_kubectl_contexts for raw kubeconfig contexts, including unregistered clusters. Provides clear when-to-use and when-not-to-use guidance with an alternative.
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?
Without annotations, the description carries full burden. It discloses 'Write operation — recorded in the audit log', indicating it is auditable. It does not detail side effects or validation limits, but the write nature is clear.
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 no wasted words. It front-loads the core purpose, then provides brief context and structured parameter details. Every sentence 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?
Given three parameters, no output schema, and no annotations, the description covers purpose, usage conditions, audit logging, and parameter meanings. It lacks error conditions or return value details, but is otherwise complete.
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 0%, so description must compensate. It provides an Args section with clear explanations: cluster_name as 'Name of the cluster', rate_per_gpu_hour with an example '$2.50/GPU/hr', and currency with default 'USD'. This adds meaningful context beyond schema titles.
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 starts with a clear verb-resource pair 'Set the GPU cost rate for a cluster.' It explicitly states the purpose and distinguishes from siblings like get_cluster_rate and get_cost_estimate by explaining it is required to enable cost estimates.
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 usage context: required to enable cost estimates, can be updated at any time, and requires organisation admin role. It lacks explicit when-not-to-use but gives clear 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?
With no annotations provided, the description carries the full burden. It discloses that this is a write operation recorded in the audit log and that generation is asynchronous. This adds significant behavioral context beyond the basic trigger action, though it could also mention idempotency or potential errors.
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 (~120 words) and well-structured. It opens with a clear purpose statement, follows with key behavioral notes (async, write operation), and ends with parameter details in an Args block. Every sentence adds value without 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 lack of output schema and annotations, the description covers the essential aspects: asynchronous behavior, parameter semantics, and polling instruction. It does not address error handling, rate limits, or what happens on invalid input. However, it references a sibling tool (get_compliance_report) for status polling, which aids agent understanding.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters5/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema only provides parameter names and types (string). The description adds critical semantic detail: valid values for report_type ('soc2', 'gdpr', 'hipaa') and the exact format for period (e.g., '2026-Q1', '2026-05', '2026'). This compensates entirely for the 0% schema description coverage.
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 ('trigger generation'), the resource ('compliance report'), and the method ('by analysing the audit log'). It also distinguishes from sibling tools by noting the asynchronous nature and the need to poll get_compliance_report.
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 explicit guidance: the tool returns immediately with a pending report, and the agent should poll get_compliance_report until ready. It mentions dependence on audit log volume for generation time, implying variable latency. However, it does not explicitly state when not to use this tool or mention alternatives like list_compliance_reports.
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, the description carries full burden. It discloses that the bind password is never returned, which is a critical behavioral trait. It also lists the config fields returned. Although it does not mention auth requirements or rate limits, for a simple read operation this is adequate.
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 four sentences, each adding value: first sentence states the action, second lists what is returned, third details the config fields, and fourth highlights the important exception about the bind password. No fluff, well-structured.
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?
For a read-only tool with no parameters and no output schema, the description is complete. It tells the agent exactly what to expect: the config fields and that the bind password is not returned. No gaps remain for an agent to invoke this tool correctly.
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?
There are no parameters in the schema, and schema description coverage is 100%. With zero parameters, the baseline is 4. The description does not need to provide param semantics, and it adds no unnecessary 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 explicitly states it returns the LDAP/AD authentication configuration for the current organization, with a specific verb ('Return') and resource ('LDAP / Active Directory authentication configuration'). It distinguishes from the sibling tool 'update_ldap_config' which is for modifications.
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 clearly indicates this tool is for viewing the current LDAP config, and the presence of 'update_ldap_config' as a sibling implies when to use this read tool vs the write counterpart. However, it does not explicitly mention when not to use it or provide alternatives, but the context is 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?
With no annotations, the description carries full burden. It discloses that anomalous spikes are flagged automatically and that the tool requires configuration via set_cluster_rate. It could be more explicit that it is read-only, but the 'get' prefix and lack of modifications imply this.
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, well-structured with a clear summary sentence followed by additional context and an arguments section. No unnecessary words.
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 one-parameter tool without output schema, the description covers the return structure (daily cost per cluster/tenant), use case, anomaly detection, and prerequisites. It could improve by mentioning response format, but it's sufficiently complete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters5/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema only defines a 'days' parameter with a default, but the description adds crucial semantics: it specifies a maximum of 90 days and clarifies the lookback window. This compensates for the 0% schema description coverage.
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 returns GPU spend trend over a specified number of days, providing daily cost series per cluster and per tenant. This distinguishes it from other get_* tools like get_budget or get_chargeback, which serve different purposes.
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 explicitly mentions a use case (detecting cost regressions after new deployments) and a prerequisite (requires cluster rates via set_cluster_rate). However, it does not compare to alternative tools or specify when not to use it, which keeps it from a higher score.
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 provided, so description carries full burden. It explains the output is a distribution by workload type and mentions the hours parameter, but does not detail output format, aggregation method, or edge cases (e.g., no data). 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?
Short, front-loaded with purpose, then usage guidance, then parameter details. No wasted sentences.
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 one parameter and no output schema, description covers purpose, usage, parameter meaning, and types. Missing return format details, but it's functional. Slightly incomplete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters5/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema has 0% description coverage (only title 'Hours'). Description adds 'Look-back window in hours (default 24)', which fully explains the parameter beyond the schema. Compensates well.
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 'distribution of GPU work by workload type for the last N hours' and lists the specific types. It distinguishes from sibling get_gpu_metrics by mentioning raw utilization percentages.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines5/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
Explicitly says 'Use this to understand what your GPU fleet is being used for' and 'For raw utilisation percentages, use get_gpu_metrics', providing clear when-to and when-not-to guidance with alternative named.
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 discloses that the raw key is never stored, only its SHA-256 hash is retained, which is a security-relevant behavioral trait. It also lists the fields returned (name, key prefix, dates, rotation history, revocation status). It does not mention permissions or side effects, but for a list operation, the disclosure is adequate.
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 long: the first states the primary purpose, the second details the fields, and the third provides a usage guideline for a sibling tool. Every sentence adds value without redundancy or wasted 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 simplicity of the tool (0 parameters, no output schema), the description is complete. It explains the tool's function, the structure of each identity, and a behavioral note about key storage. It also mentions the sibling for creation, covering the necessary context for an agent to use the tool correctly.
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?
The input schema has 0 parameters, so schema coverage is 100% and the baseline is 4. The description adds context about what each identity contains (e.g., key prefix, creation date, last-used timestamp, rotation history, revocation status, and the hash note), which helps the agent understand the output format despite no output 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 'List all agent machine identities' with a specific verb ('List') and resource ('agent machine identities'). It distinguishes from the sibling 'create_agent_identity' by being a read-only operation, and the purpose is unambiguous.
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 explicitly directs to use 'create_agent_identity' for issuing new identities, providing an alternative for a related operation. However, it does not explicitly mention when not to use this tool relative to other siblings like 'revoke_agent_identity' or 'rotate_agent_identity', though the purpose is clear enough to infer that this is for listing only.
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 explains that revocation is immediate, irreversible, retains the record for audit, and logs the write operation. However, it does not mention authentication requirements or impact on dependent resources.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters5/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Despite 0% schema description coverage, the description includes a comprehensive 'Args' section that explains each parameter's meaning and usage (e.g., gateway_id disambiguation, env injection), adding significant value beyond the bare 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's action ('Deploy an AI model onto a GPU cluster') and distinguishes it from the sibling tool helm_upgrade for custom Helm chart deployments, providing a specific verb 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 Guidelines5/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
Explicitly states when to use ('standard model deployments') and when not to (custom Helm deployments, directing to helm_upgrade), and notes that it is a write operation recorded in the audit log.
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 details the output structure (status, notes, evidence URL) but does not explicitly state the tool is read-only, though 'List all' implies no side effects. With no annotations provided, a more explicit declaration of non-destructiveness would be ideal.
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 short paragraphs with no extraneous words. The first paragraph defines the tool's action and output, the second offers an alternative. Every sentence adds value, making it highly efficient.
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 and zero parameters, the description completely covers what the tool does, what it returns, and when to use an alternative. It provides sufficient context for an AI agent to select and invoke the tool correctly.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters5/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has no parameters, so schema_description_coverage is 100%. The description adds significant meaning by describing the pre-seeded articles and the output format, compensating fully for the empty schema and providing all necessary context.
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 'List' and the resource 'AI Act compliance controls', specifying what it returns (their status). It is distinct from sibling tools like get_ai_act_score (aggregated percentage) and update_ai_act_control (mutates controls), making 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 Guidelines5/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description explicitly directs users to use get_ai_act_score for aggregated compliance percentage, providing clear when-to-use guidance vs alternatives. It also explains that 6 articles are pre-seeded, setting expectations for the tool's scope.
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?
No annotations are provided, so the description carries the burden. It discloses that it's a 'Write operation — recorded in the audit log' and notes that automatic resolution may still occur later, indicating it's not a permanent override. However, it does not mention permission requirements or potential 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?
The description is 7 sentences, each earning its place. The purpose is front-loaded in the first line, followed by usage guidance, behavioral notes, and parameter details. No redundant or vague statements.
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 2 simple parameters, no output schema, and no annotations, the description covers the operation purpose, usage context, behavioral traits (write/audit), and parameter explanations. It is sufficiently complete for an AI agent to select and invoke the tool correctly.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters5/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 0%, but the description's Args section adds meaningful context: anomaly_id is described as 'UUID of the anomaly to resolve (from list_anomalies)' and reason as 'Optional free-text explanation'. This provides origin and optionality beyond the raw schema types and titles.
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 'Manually mark an anomaly as resolved', which uses a specific verb and resource. It distinguishes the tool from siblings like list_anomalies and get_open_anomalies by specifying it's a manual resolution action, and contrasts with automatic resolution.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines5/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
Explicitly states 'Use when the underlying issue has been addressed outside VibOps' and explains that automatic resolution still applies otherwise. This provides clear when-to-use and when-not-to-use guidance, referencing the alternative automatic process.
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, the description carries full burden. It discloses that write operations are recorded in audit log and warns against destructive commands. However, it doesn't mention potential side effects or failure behavior, which would be useful for a tool that can execute arbitrary commands.
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?
Concise and well-structured: purpose, usage guidelines, suitable/avoid commands, audit info, then parameter descriptions. Every sentence adds value 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?
For a tool with 3 parameters, no output schema, and no annotations, the description is highly complete: covers purpose, usage guidelines, behavioral traits, and parameter semantics. Only minor gap is lack of output return format, but that's acceptable for a command execution tool.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters5/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so description must explain all parameters. It does so thoroughly: cluster_name target cluster, command as list without 'kubectl' prefix with example, gateway_id optional with guidance on when to omit/provide. Adds meaning beyond 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?
Clearly states it executes kubectl commands on a cluster. Distinguishes from siblings by specifying that it should only be used for operations not covered by dedicated tools, and lists suitable commands (get, describe, logs) as examples.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines5/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
Explicitly states when to use (operations not covered by dedicated tools) and when not to use (destructive commands). Lists alternatives: scale_deployment, deploy_model, helm_upgrade, helm_uninstall. Also mentions audit logging for write operations.
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?
No annotations provided, so description carries full burden. It discloses partial update behavior, role requirement, and password encryption, but does not detail consequences of disabling LDAP or irreversible 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?
Well-structured, front-loaded with purpose, followed by behavioral details, prerequisites, and parameter list. Each sentence adds value 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 8 parameters and no output schema, the description covers parameter meanings, prerequisites, and usage context sufficiently for an agent to invoke correctly.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters5/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 0%, but the description fully documents all 8 parameters with examples, defaults, and notes on password encryption and search filter formatting.
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 states 'Update the LDAP / Active Directory configuration for the current organisation' with a specific verb and resource, clearly distinguishing it from sibling tools like get_ldap_config.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines5/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
It explains partial update behavior ('Only supplied fields are updated'), prerequisites for enabling LDAP, required role ('Requires org_admin role'), and provides search filter examples for different LDAP servers.
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?
The description explains the scoring methodology in detail: weighted average with control values (compliant=1.0, partial=0.5, non_compliant=0.0) and exclusion of not_applicable controls, which is behavioral context beyond annotations (none provided).
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: first states the action and output, second explains calculation, third provides companion tool. No wasted words, front-loaded.
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 parameters and no output schema, the description fully covers what the tool does, how it computes the score, and how to get detailed breakdown, making it complete for an AI agent.
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?
Input schema has 0 parameters (100% coverage), so the baseline is 4. The description does not add parameter info but explains the return value semantics, which is sufficient.
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 the overall AI Act compliance score (0–100) and distinguishes it from the sibling tool list_ai_act_controls by mentioning it provides per-article breakdown.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines5/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
It explicitly recommends using list_ai_act_controls to see per-article breakdown and identify gaps, providing clear context on when to use this tool versus the alternative.
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?
The description discloses key behavioral traits: generates new key, invalidates previous one, new key returned once, write operation recorded in audit log. Since no annotations are provided, the description fully covers 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?
Description is concise, front-loaded with purpose, and every sentence adds value. No redundancy 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 simple single-parameter tool with no output schema, the description covers all necessary context: what it does, when to use, parameter meaning, and note about storing the key. It is sufficient for an agent to correctly invoke the tool.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters5/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The only parameter 'identity_id' is described as 'UUID of the identity to rotate (from list_agent_identities)', providing source and type beyond the empty schema description. Schema coverage is 0%, so description compensates fully.
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 ('Rotate the API key for an agent identity') and distinguishes from the sibling tool 'revoke_agent_identity' by noting that identity itself is preserved.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines5/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
Explicitly states when to use this tool ('scheduled key rotation or if a key is suspected of being compromised') and provides an alternative ('revoke_agent_identity' for permanent disablement).
