Server Quality Checklist

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

Latest release: v1.2.2
Disambiguation4/5
Most tools have distinct purposes, but there is potential confusion between get_client and get_client_by_clientid (both retrieve a client) and between assign_client_role_to_user and assign_realm_role_to_user (both assign roles, just different scopes). Descriptions clarify, but the large number of tools may cause some ambiguity.
Naming Consistency5/5
All tools follow a consistent snake_case verb_noun pattern (e.g., create_user, list_clients, update_realm_settings). Longer names like add_user_to_group are also consistent with verb_object_preposition_target style. No mixing of conventions.
Tool Count4/5
47 tools is substantial but appropriate for a comprehensive Keycloak administration server covering realms, users, groups, clients, roles, and sessions. Each tool has a defined role, though a few could be merged without loss of clarity.
Completeness4/5
The tool surface is very broad, covering CRUD for all major entities plus password resets, session management, role assignments, and realm configuration. Notable gap: no tool to list a user's client roles (only realm roles). Otherwise, well-rounded.
Average 3.4/5 across 47 of 47 tools scored. Lowest: 2.7/5.

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?
With no annotations, the description carries the full burden of disclosing behavioral traits. It only states the action ('Add') but does not mention that this is a write operation, what side effects occur (e.g., affects realm configuration), required permissions, or idempotency. The agent is left guessing about consequences.
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, with 2-3 sentences covering purpose, parameters, and return. It is front-loaded with the action. However, it could be slightly restructured to be even more direct (e.g., 'Adds a group to the realm's default groups') without losing clarity.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the lack of annotations and output schema presence, the description is incomplete. It explains parameters and return but omits crucial context: whether the operation is idempotent, error conditions (e.g., invalid group ID), and what 'default group' means in the realm configuration. A more complete description would help the agent use the tool safely.
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?
Schema description coverage is 0%, so the description must add meaning. It explains 'group_id' as 'Group ID to add as default' and 'realm' as 'Target realm (uses default if not specified)', which adds some context beyond the schema titles. However, it does not clarify format, accepted values, or behavior when the group already exists.
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 action ('Add a default group') and the resource ('to the realm'), which distinguishes it from sibling tools like 'remove_realm_default_group' and 'get_realm_default_groups'. However, the phrasing could be slightly more precise: it could explicitly say 'Add a group to the realm's default groups list'.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance is provided on when to use this tool versus alternatives. There is no mention of prerequisites (e.g., group must exist) or when not to use it (e.g., if group is already default). The description lacks context to help an agent choose correctly among sibling tools.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden but only states the action. It does not disclose whether roles are added or overwritten, required permissions, idempotency, or side effects. The minimal description fails to inform the agent about critical 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.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is concise, using a structured docstring format with Args and Returns sections. Every sentence is necessary, though the Returns line could be more detailed.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool has 4 parameters (3 required), no enums, and an expected output schema (not shown), the description lacks important contextual details: error conditions, role existence requirements, behavior on duplicates, and authentication needs. It is not sufficiently complete for an agent to invoke correctly without additional knowledge.
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?
Schema description coverage is 0%, so the description must compensate. However, it merely restates parameter names and types from the schema without adding new meaning (e.g., format constraints, relationships between parameters, or how 'realm' defaults work). The return value 'Status message' is too vague.
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: 'Assign client roles to a user.' This verb+resource construction is specific and distinguishes it from sibling tools like 'assign_realm_role_to_user' and 'add_user_to_group'.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides no guidance on when to use this tool versus alternatives, no prerequisites, and no conditions where it should not be used. Given the presence of multiple assignment tools as siblings, this is a significant gap.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided; description only says 'Assign' and returns a status message. Does not disclose side effects (e.g., idempotency, permission requirements, what happens if role already exists). For a mutation 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.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Short and to the point, with a one-line summary followed by parameter descriptions. No unnecessary text, but could be slightly more structured (e.g., bullet points for args vs returns).
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?
Lacks details about prerequisites, error handling, or what the status message contains. For a mutation tool with 3 parameters and no annotations, more context (e.g., required permissions, behavior on failure) would be expected.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema has 0% description coverage, but the description adds meaning: 'user_id' (User ID), 'role_names' (list of role names), 'realm' (target realm with default). However, it does not explain constraints or accepted formats beyond the schema 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 'Assign realm roles to a user' with specific verb and resource. However, it does not differentiate from sibling tools like assign_client_role_to_user or remove_realm_role_from_user, which could cause confusion.
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. Only mentions a default realm behavior, but lacks when-to-use or when-not-to-use context.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries full burden but fails to disclose behavioral traits like whether read-only access is sufficient, what happens if the id is invalid, or if the secret is returned in plaintext. The function name implies read-only, but no explicit behavioral confirmation.
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, using only one sentence plus parameter descriptions. It is front-loaded with the core purpose. However, it could be structured slightly better with explicit sections for when to use.
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 simple parameters and existence of an output schema, the description is minimally complete. However, for a security-sensitive tool like retrieving a client secret, more context about security implications or behavior on missing secrets would be beneficial.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The description adds minimal semantics beyond the schema: it explains that 'id' is the client's database ID and 'realm' uses a default if omitted. With 0% schema description coverage, this is helpful but limited, as the parameter names are already fairly self-explanatory.
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 gets a client secret, with 'get' as the verb and 'client secret' as the resource. However, it does not differentiate from the sibling tool 'regenerate_client_secret' or specify if this retrieves the current or full secret, slightly reducing specificity.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance is provided on when to use this tool versus alternatives like 'regenerate_client_secret'. There is no mention of prerequisites, such as required permissions or whether the realm parameter is typically needed.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior1/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, and the description only says 'Delete a user.' It does not disclose behavioral traits like whether deletion is immediate, irreversible, cascading, or requires special permissions.
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: one sentence for purpose, then parameter and returns descriptions. It is front-loaded with the main action and uses minimal words.
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 that this is a deletion tool, the description lacks context on consequences, default behavior of realm, error handling, or output details. Although an output schema exists, the description provides no behavioral context beyond the basic action.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, requiring compensation. The description provides brief parameter descriptions ('user_id: The user's ID', 'realm: Target realm (uses default if not specified)'), adding some meaning beyond the schema titles, but it is minimal and does not fully compensate 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 states 'Delete a user,' which is a specific verb and resource. It clearly distinguishes from sibling delete tools like delete_client, delete_group, and delete_realm_role.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool versus alternatives, such as other deletion tools or deactivation methods. No context on prerequisites or scenarios to avoid.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided; description only defines parameters and says 'Update realm settings'. Does not disclose whether update is partial or full, side effects, authentication needs, or idempotency.
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?
Front-loaded with purpose, then clean parameter list. Appropriate length given parameter count; no wasted words. Could group similar parameters but not necessary.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Despite many parameters, description omits key context: update semantics (patch vs replace), return value details (vague 'Status message'), and relationships between parameters. Incomplete for a tool of this complexity with no annotations.
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?
Adds brief but useful meaning for each of the 25 parameters (e.g., 'Whether realm is enabled'), compensating for 0% schema description coverage. Could provide more detail on constraints or defaults, but sufficient for basic understanding.
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?
Starts with 'Update realm settings', clearly indicating verb and resource. Parameter list makes scope evident. Does not explicitly distinguish from sibling tools like update_realm_events_config, but name and parameters imply focus on general settings.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool versus alternatives (e.g., update_realm_events_config for events config). Lacks context on prerequisities 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.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full burden for behavioral context. It only states the operation and parameter list, omitting side effects, permission requirements, or behavior when inputs are invalid (e.g., user already in group).
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 brief and well-structured with an Args/Returns section. It contains no extraneous information, though it could be more informative without sacrificing conciseness.
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?
For a tool with 3 parameters and no output schema details beyond 'Status message', the description is incomplete. It lacks information on error handling, idempotency, or what the status message indicates, which is crucial for an agent to use it reliably.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The description adds limited meaning: it clarifies that 'realm' is optional and uses a default if not specified. However, it does not explain the format or origin of 'user_id' or 'group_id', and the schema itself lacks property descriptions (0% 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 'Add a user to a group', which is a specific verb-resource combination. It distinguishes itself from siblings like 'remove_user_from_group' and 'create_group' by the action and target.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides no guidance on when to use this tool versus alternatives, nor does it mention prerequisites (e.g., user or group must exist) or potential errors (e.g., duplicate membership).
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 disclose behavior. It only says 'Create a new group.' without mentioning side effects, overwrite behavior, permissions required, or error conditions. 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.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is concise with a one-line summary, parameter list, and return line. No redundant text, but could be more structured without being verbose.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the lack of annotations and low schema coverage, the description is minimal. It does not cover error handling, prerequisites, or return value details beyond 'Status message', leaving significant gaps for an AI agent.
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 description coverage, the description must compensate. It provides brief explanations for each parameter (e.g., 'Group name', 'Target realm (uses default if not specified)'), which adds some value but lacks details on formats or constraints (e.g., attributes structure).
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 'Create a new group.' which is a specific verb+resource, and distinguishes from siblings like update_group, delete_group, and list_groups.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides no guidance on when to use this tool versus alternatives. It lacks usage context, prerequisites, or when-not-to-use conditions.
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, and the description fails to disclose behavioral traits such as whether the deletion cascades to associated data (e.g., client roles), required permissions, or side effects. This is a significant gap for a mutating tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is short and to the point, covering the essential information without unnecessary verbosity. However, the 'Returns' section is vague (''Status message'') and could be slightly expanded without harming conciseness.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's mutating nature, lack of annotations, and presence of an output schema (content unknown), the description does not provide enough context about side effects, idempotency, or error conditions. It's incomplete for safe agent usage.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The description includes brief explanations for both parameters: 'The client's database ID' for id and 'Target realm (uses default if not specified)' for realm. This adds value beyond the schema, which has no descriptions, but the explanations are minimal.
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 'Delete a client,' using a specific verb and resource. This clearly distinguishes it from sibling tools like 'create_client', 'update_client', and others.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance is provided on when to use this tool versus alternatives. Sibling tools include related operations like 'create_client', 'update_client', 'get_client', etc., but the description does not specify any conditions or warnings.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so the description must disclose behavioral traits. It only states 'Delete a group' without mentioning permissions, reversibility, cascading effects, or any side effects, leaving significant behavioral gaps.
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 short and front-loaded with the main action. The args listing is somewhat redundant with the schema but does not harm conciseness. Could be slightly more compact.
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 a simple delete operation with two parameters and an output schema, the description is minimally adequate. However, it lacks information about permissions, error handling, or what the 'Status message' contains, leaving some completeness gaps.
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: 'group_id: Group ID' and 'realm: Target realm (uses default if not specified)'. This provides basic context but does not fully compensate 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 clearly states 'Delete a group,' which is a specific verb-resource pair. It easily distinguishes from sibling tools like 'delete_user' or 'delete_client' due to the explicit mention of 'group'.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool versus alternatives such as 'remove_user_from_group' or 'remove_realm_default_group'. The description lacks context for proper selection.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Without annotations, the description should disclose behavioral traits. It does not mention that the tool is read-only, idempotent, or error behavior (e.g., client not found). Minimal 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 (under 50 words) with a clear structure: purpose, args, returns. No redundant 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?
For a simple get tool, the description covers the basics. The existence of an output schema reduces the need to describe return values. However, it lacks safety cues (read-only) and error handling context.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 0%, so the description adds necessary context. It explains both parameters: client_id and realm (noting default behavior). However, it could improve by specifying the format or source of 'realm'.
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 action ('Get a specific client by client ID') and resource. However, it does not differentiate from the sibling tool 'get_client', which could be ambiguous.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool versus alternatives. The description only states the function without context on prerequisites or appropriate scenarios.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full burden. It mentions the optional realm parameter and that a default is used, but does not disclose potential errors, authorization needs, or whether the operation is read-only (implied but not stated). Minimal behavioral insight.
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 and front-loaded; the first sentence captures the main purpose. The Args/Returns sections add structure, though partially redundant with schema. It is efficient but not waste-free.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple read tool with one optional parameter and an output schema (presence indicated but content unknown), the description is adequate but not complete. It does not detail the return object's structure or parameter constraints, leaving some questions for the 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?
With 0% schema description coverage, the description compensates by explaining that the realm parameter is optional and uses a default if not specified. This adds meaning beyond the schema's type and default value, though further clarification on valid realm values would improve it.
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 first sentence clearly states the tool's purpose: 'Get information about the current realm.' It specifies the verb and resource, distinguishing it from siblings like get_accessible_realms (which lists realms) and other get_* tools. However, it does not enumerate what information is included, so a small gap for precise purpose.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool versus alternatives such as get_accessible_realms, get_realm_events_config, or get_realm_role. The description lacks explicit context or exclusions, leaving the agent to infer usage from the name alone.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Lacks annotations; description does not disclose side effects, behavior on invalid id, or whether partial updates are supported.
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?
Structured with Args/Returns sections, but somewhat lengthy due to listing all 11 parameters individually.
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?
Does not explain return value ('Status message') in detail, and omits behavioral context such as error handling or required permissions.
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 lists each parameter with a short label, but adds minimal meaning beyond schema titles; 0% schema coverage means description should compensate more.
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 the verb 'update' and specifies the resource 'existing client', clearly differentiating from sibling tools like create_client and delete_client.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool versus alternatives (e.g., create_client, delete_client) or prerequisites like client existence.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are present, and the description does not disclose behavioral traits such as whether the update is partial or full, if permissions are required, or any side effects (e.g., changing event listeners may affect running services). The description only lists parameters with minimal explanations.
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, using a standard docstring format with Args and Returns sections. It front-loads the main action and lists parameters succinctly, though it could be more compact by omitting trivial parameter descriptions that mirror the schema.
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?
For a tool with 6 optional parameters and no required fields, the description lacks detail on default behaviors, the impact of partial updates, and the format of the status message. The tool's complexity is not matched by the description, leading to potential ambiguity for an AI agent.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, but the description adds one-line meanings for each parameter (e.g., 'events_enabled: Enable events'). While this provides context beyond the property names, the descriptions are terse and do not clarify types, constraints, or dependencies between 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 'Update realm events configuration', which is a specific verb+resource action. The existence of a sibling 'get_realm_events_config' distinguishes this as the write counterpart, making the purpose unambiguous.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance is provided on when to use this tool versus alternatives (e.g., get_realm_events_config for reading, or other update tools). There are no prerequisites, context, or exclusions mentioned.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, and the description lacks details on behavioral traits such as idempotency, error handling (e.g., user not found), or required permissions. The 'Status message' return is vague.
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 with a clear parameter list and return statement. It could be improved by front-loading the purpose more prominently, but it's 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 9 parameters and many sibling tools, the description lacks context on side effects, required permissions, error conditions, and return value details (output schema exists but not elaborated). Incomplete for effective use.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the description's parameter explanations add value. However, they are minimal (e.g., 'Updated user attributes' is vague). Compensates partially but not 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 'Update an existing user', specifying the action and resource. It distinguishes itself from siblings like create_user, delete_user, and get_user by its verb and focus on modification.
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 over alternatives, prerequisites (e.g., user must exist), or situations where it should not be used. With many siblings, this omission is significant.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must disclose all behavioral traits. It states the action (logout all sessions) but does not mention side effects, required permissions, or whether the tool is destructive or reversible. The return is a vague 'Status message' without details.
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, using only two sentences plus structured sections for Args and Returns. Every word is necessary and adds value, making it efficient for an AI agent to parse.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The description covers the basic action and parameters, but lacks context about when to use this tool among many siblings. It does not explain the impact on the user's sessions or the system, and the output schema (Status message) is not elaborated. For a simple tool, it is minimally adequate.
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 description adds meaning beyond the schema by explaining that 'realm' is optional and uses a default when not specified, and clarifies that 'user_id' is the user's ID. 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.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states 'Logout all sessions for a user,' which is a specific verb-resource combination. It distinguishes from sibling tools like 'get_user_sessions' by indicating a write operation, but does not explicitly differentiate from 'remove_all_user_sessions', which appears to be a similar action.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides no guidance on when to use this tool versus alternatives like 'remove_all_user_sessions' or 'get_user_sessions'. There is no mention of prerequisites, context, or scenarios where this tool is preferred.
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 of behavioral disclosure. It indicates mutation ('Update') but does not mention idempotency, error conditions, required permissions, or side effects. This is insufficient for a write operation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is concise (3 sentences plus a bullet list) and front-loaded with the purpose. Every line earns its place, and the Args/Returns structure is clear and scannable.
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 moderate complexity (5 parameters, 1 required) and the presence of an output schema, the description covers the basic functionality. However, it lacks contextual aspects like prerequisites, side effects, or usage constraints, making it merely adequate.
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?
The description adds minimal meaning beyond the input schema, e.g., 'New group name' for 'name' and 'New group attributes' for 'attributes'. However, it does not clarify types or constraints, especially for 'attributes' (a dict of string arrays) and 'realm'. With 0% schema description coverage, the description should compensate more.
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 'Update a group' and lists specific parameters (group_id, name, path, attributes, realm), making the verb, resource, and scope obvious. It distinguishes from sibling tools like create_group and delete_group by focusing on update functionality.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides no guidance on when to use this tool versus alternatives, nor does it mention prerequisites or exclusions. It simply lists parameters, leaving the agent without context for appropriate invocation.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, and the description only lists parameters without disclosing side effects, required permissions, or consequences of updates. The return is vaguely described as 'Status message'.
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?
Concise, with clear parameter list. The 'Args:' block is somewhat verbose but not excessive.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
An output schema exists, so return details are less critical. However, the description doesn't clarify whether it's a partial update or full replacement, which would aid understanding.
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?
Parameter descriptions like 'Current role name' and 'New description' add basic meaning beyond schema titles, but no format or behavioral constraints are given. Schema coverage is 0%, so description partially compensates.
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 'Update a realm role.' and lists the parameters, which distinguishes it from create_realm_role and delete_realm_role among the siblings.
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. creating, deleting, or other update tools. No prerequisites or conditions mentioned.
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 disclose behavior. It states it creates a role (write operation) and returns a status message, but it does not mention side effects, permissions required, idempotency, or what happens if the role already exists.
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, front-loaded with the purpose, and uses a clear Args/Returns structure. It contains no unnecessary words, though the format is slightly code-like.
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 5 parameters, no annotations, and many sibling tools, the description lacks completeness. It does not explain the meaning of 'composite' vs 'client_role' in this context, nor does it clarify the return value beyond 'Status message.' The output schema exists but is not referenced.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the description needs to compensate. It provides brief parameter descriptions (e.g., 'realm: Target realm (uses default if not specified)'), which adds some meaning. However, 'composite' and 'client_role' are only restated without explanation of their purpose in a realm role 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 'Create a new realm role,' which is a specific verb+resource. It distinguishes from sibling tools like 'create_client_role' and 'assign_realm_role_to_user' by specifying 'realm role.'
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies when to use (creating a realm role) but provides no explicit guidance on when not to use or how it differs from alternatives like 'create_client_role' or 'update_realm_role.' No comparison to siblings.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full burden. It only states the group is retrieved and returns a Group object, but does not disclose any behavioral traits such as required permissions, error handling (e.g., if group not found), or 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 extremely concise with no wasted words. The main purpose is front-loaded, followed by structured Args and Returns sections. Every sentence is necessary.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple retrieval tool with an output schema (Group object), the description is mostly adequate. However, it lacks context on error cases, permissions, or the fact that group_id must exist. Given no annotations, more completeness would be beneficial.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 0%, so description must compensate. It adds basic explanations: 'group_id: Group ID' and 'realm: Target realm (uses default if not specified)'. The realm's default behavior is clarified, but group_id is tautological. Overall, partial compensation for low schema 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 explicitly states 'Get a specific group by ID.' The verb 'Get' and resource 'group' are clear, and it distinguishes itself from sibling tools like list_groups (which lists all groups) and create_group (which creates a group).
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance is provided on when to use this tool versus alternatives like list_groups or get_group_members. There is no mention of prerequisites, when-not to use, or context-specific hints.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries full burden but only states it returns a list of active sessions. It does not disclose side effects, permissions, or constraints such as session expiration, pagination, or error states. Minimal behavioral insight.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is extremely concise with only one sentence for purpose and structured Args/Returns sections. Every word adds value, and there is no redundancy or fluff.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the output schema exists, description need not detail return structure, but it lacks behavioral context like whether the tool requires admin privileges or works only for the current user. It is adequate for a simple read operation but incomplete for nuanced selection.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 0%, so description must add meaning. It explains that 'realm' is optional and defaults to a default value, adding some context. However, it does not elaborate on the format or constraints of 'user_id' or 'realm,' leaving room for ambiguity.
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 'Get' and the resource 'active sessions for a user,' making the tool's purpose specific and unambiguous. It distinguishes itself from sibling tools like 'remove_all_user_sessions' by focusing on retrieval rather than removal.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance is provided on when to use this tool versus alternatives like 'logout_user' or 'remove_all_user_sessions.' There is no mention of prerequisites, context-dependent usage, or exclusions, leaving the agent to infer.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, and description only mentions 'Returns: List of client roles' without disclosing pagination behavior, ordering, or side effects. Implicitly read-only, but not explicit.
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 concise with a clear docstring structure (Args/Returns). The main sentence is direct, and parameter descriptions are efficient, though some repetition exists with the schema.
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?

Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so burden is on description. It provides basic meanings for each parameter (e.g., 'Pagination offset', 'Search string'), but lacks examples, constraints, or format details.
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 roles for a specific client', specifying the verb (list) and resource (roles), which distinguishes it from sibling tools like create_client_role or list_realm_roles.
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 such as list_realm_roles or search tools; no context on prerequisites 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.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must cover behavioral traits. It only states the action and return type ('Status message'), omitting side effects, required permissions, or any constraints. The destructive nature is implied but not explicitly disclosed.
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 sentences and a bullet-like args list. It is front-loaded with the purpose and has no redundant content. Every sentence adds value.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple tool with 3 parameters and no enums, the description covers purpose, parameters, and return value. However, it misses usage guidelines and behavioral context (e.g., prerequisites, error cases), leaving gaps in completeness.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the description adds some meaning beyond titles. It briefly explains each parameter: user_id, group_id, and realm with default behavior. However, it lacks format details or allowed values, making it minimally adequate.
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 'Remove a user from a group,' which is a clear verb+resource statement. This effectively distinguishes it from sibling tools like 'add_user_to_group' and 'remove_realm_default_group.'
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides no guidance on when to use this tool versus alternatives. With many sibling tools (add_user_to_group, remove_realm_role_from_user), explicit usage context is missing, leaving the agent without decision support.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must disclose side effects and constraints. It only states 'Create a new client' and lists parameters, omitting details like uniqueness of client_id, permissions required, or idempotency. Minimal transparency beyond mutation.
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 clear opening line, an Args section, and a Returns line. It is not overly verbose, though the length is driven by the number of parameters. Each sentence adds value.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Covers listing, filtering, pagination, and return format. Missing error handling or rate limits, but sufficient for a basic listing 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%, but description adds meaningful descriptions for all parameters (e.g., 'Filter by client ID (partial match)', 'Pagination offset'), compensating well.
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 'List clients in the realm', providing a specific verb and resource. However, does not explicitly differentiate from sibling tools like get_client or get_client_by_clientid.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool versus alternatives. Lacks context for choosing list_clients over get_client or get_client_by_clientid.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are present, so the description should disclose behavioral traits. It only states the operation and return type, without any information about authentication, side effects, 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?
The description is extremely concise, using only two sentences to convey the essential information without unnecessary words.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
While the tool is simple with no parameters, the description lacks details about what 'accessible' means, potential prerequisites, or output structure. It is minimally adequate.
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, so the description does not need to add semantic value. The schema coverage is 100%, achieving a baseline of 4.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool retrieves 'accessible realms' and the return type is a list. It is distinct from sibling tools that focus on specific realms or roles.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance is provided on when to use this tool versus alternatives. It does not mention context or exclusions, leaving the agent to infer usage.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description bears full responsibility for behavioral disclosure. The term 'regenerate' implies a mutation (destructive change), but no details are given about side effects (e.g., old secret invalidation, permission requirements, rate limits). The return of a new client secret object is stated, but that is minimal.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is extremely concise with a clear structure: a one-sentence summary followed by an Args section and a Returns section. Every sentence is necessary and adds value, with no redundancy or filler.
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 that an output schema exists (not shown but noted), the description does not need to detail return values. However, the tool is simple with two parameters, and the description covers their semantics. Yet it lacks usage context (when to call) and behavioral details (side effects), which are partially compensated by the tool's name and schema. Overall adequate but missing some completeness for an agent to use correctly.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
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 adds meaning beyond schema titles: 'id' is clarified as 'The client's database ID', and 'realm' is explained as 'Target realm (uses default if not specified)'. This is helpful, though it could specify what the default realm is or how it is determined.
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 ('Regenerate the client secret') and identifies the resource ('client secret'). The verb 'regenerate' distinguishes it from sibling tools like 'get_client_secret' (read) and 'update_client' (general update). The parameter names and brief descriptions further clarify the scope.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides no guidance on when to use this tool versus alternatives. For example, it does not mention that this invalidates the current secret or that it should be used only when secrets are compromised. Sibling tools exist for similar operations, but no comparative advice is given.
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 side effects, permissions required, or error conditions. The return value is vaguely described as 'Status message'.
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, uses a clear docstring format, and front-loads the purpose.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple removal tool, the description is adequate but lacks details on idempotency, error handling, and prerequisites. No output schema is provided but returns are mentioned.
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 description adds meaning by explaining each parameter: group_id as the ID to remove and realm as the target with a default. Schema coverage is 0%, so the description compensates effectively.
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 'Remove a default group from the realm' with a specific verb and resource. It distinguishes from siblings like 'add_realm_default_group'.
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 or avoid this tool, nor mentions alternatives. The description simply states what it does without context.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries full burden for behavioral disclosure. It only states the action and vague return type, omitting details about permissions, reversibility, side effects (e.g., session impact), or error cases.
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, using a single introductory sentence followed by a structured list of arguments and return value. Every element serves a purpose with 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?
The description covers basic functionality and parameter roles, but lacks details on realm role semantics, required user membership, error handling, or the structure of the returned 'Status message'. Despite an output schema existing, the description alone is not fully self-contained.
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 has 0% description coverage, so the description must compensate. It provides brief but clear meanings for each parameter: user_id as 'User ID', role_names as 'List of role names to remove', and realm as 'Target realm (uses default if not specified)'. This adds value over the schema's bare 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 uses a specific verb 'remove' with a clear resource 'realm roles from a user'. It directly states the function's purpose and differentiates it from sibling tools like 'assign_realm_role_to_user', which performs the opposite operation.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides no explicit guidance on when to use or not use this tool. It does not mention alternatives or prerequisites, leaving the agent to infer usage solely from the action description.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description only says 'Reset a user's password' and 'Returns: Status message,' omitting side effects like session invalidation or notification.
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 one-line purpose, followed by structured Args and Returns sections, every sentence adding value.
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?
Missing behavioral context (e.g., permissions, side effects) and usage guidance; output schema exists but return is vague ('Status message'), insufficient for a security-sensitive 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?
All four parameters (user_id, password, temporary, realm) are explained with clear meanings and defaults, compensating for the input schema's lack of descriptions (0% 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?

Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance is provided on when to use this tool versus alternatives (e.g., update_user) or prerequisites like admin permissions.
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 accurately describes a read operation with parameter details (e.g., effective for composite roles), but does not disclose behavior like error handling or side effects. Basic transparency with no contradictions.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is concise at 7 lines, covering purpose, parameters, and return value. It avoids unnecessary detail but could be better structured (e.g., separate sections). No redundant content.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple retrieval tool with an output schema (not shown), the description is adequate. It states the return type as a list of realm roles but lacks details on potential filters or error cases. Meets minimum viability.
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 the description adds meaning beyond the schema. For example, it explains that 'effective' retrieves composite roles, which is not apparent from the schema. This compensates 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?

Description implies usage to get events config for a realm, but no explicit when-not or alternative tools mentioned. Usage is inferred from purpose.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must disclose behavior. It only states the basic read operation without detailing any side effects, authentication requirements, rate limits, or safety profile. The tool is likely read-only, but this is not confirmed.
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 the main purpose in the first sentence and additional details in a standard docstring format. No unnecessary text; 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?
For a simple retrieval tool with two parameters and an output schema, the description covers the basics. It states the return type (list of groups). Given the output schema exists, more detail is not strictly necessary, but the description could mention any pagination or restrictions.
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 no descriptions (0% coverage), so the description adds value by explaining that 'user_id' is the user's ID and 'realm' is optional with a default. This clarifies the meaning and default behavior beyond the schema alone.
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: 'Get all groups for a user.' This specifies the action (get) and resource (groups for a user), distinguishing it from siblings like 'get_group' (single group) or 'add_user_to_group' (adds user to a group).
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 implicitly assumes the user knows when to retrieve groups for a user, but it does not explicitly state when to use this tool versus alternatives. There is no mention of alternatives or when not to use it, which would be helpful given the many sibling tools.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are present, so the description carries full burden. It states removal of all sessions but omits behavioral traits like irreversibility, effect on active users, or authentication status. This is insufficient for a potentially destructive operation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Extremely concise: two sentences plus structured Args/Returns. Every phrase provides value, and the main action is front-loaded.
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 tool (one param, output schema exists for return), the description is adequate. However, for a destructive action, a bit more behavioral context (e.g., impact on users) 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 description adds meaning to the 'realm' parameter by explaining it targets the realm and uses a default if unspecified. Since schema description coverage is 0%, this compensates well for the single optional parameter.
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 'Remove all sessions for all users in the realm' with specific verb and resource scope. It distinguishes from siblings like 'logout_user' (single user) and 'get_user_sessions' (list only).
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 basic context (realm parameter defaults) but no explicit when-to-use or alternatives. It neither says when not to use nor compares with related tools.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must disclose behavior. It states 'List all realm roles' and describes parameters, but does not mention permissions, safety, error cases, or pagination behavior beyond the parameter names. This is adequate for a simple read operation but lacks depth.
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: a single line for purpose, a parameter list, and a returns statement. No redundant text, and the key action is front-loaded. Every sentence earns its place.
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 4 parameters and no annotations, the description covers basic usage but misses context: it doesn't clarify whether 'all realm roles' is per-realm or across realms (despite the realm parameter), and lacks mentions of prerequisites, error cases, or default behavior for omitted parameters. The presence of an output schema partially offsets the need for return value 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?
Schema description coverage is 0%, so the description compensates by explaining each parameter: 'first: Pagination offset', 'max: Maximum results size', 'search: Search string', 'realm: Target realm (uses default if not specified)'. This adds meaningful context beyond the schema's minimal type info.
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 realm roles,' providing a specific verb and resource. This distinguishes it from sibling tools like get_realm_role (single role) and create/update/delete_realm_role.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies usage for listing all roles, but lacks explicit guidance on when to use this tool versus alternatives like list_client_roles or get_realm_role. No exclusions or context for search/pagination are provided.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the burden. It does not disclose behavioral traits like read-only nature, authentication requirements, rate limits, or performance implications. The 'Returns' line adds minimal 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 brief and well-structured with clear sections (Args, Returns). Every sentence adds value, and the format is front-loaded for quick understanding.
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 7 optional parameters and an output schema, the description covers all parameters and return type adequately. No additional context is needed for this list 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?
With 0% schema description coverage, the description compensates fully by explaining each parameter's purpose (e.g., 'search: Search string for username, first/last name, or email'). It adds meaning beyond the JSON 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 users in the realm' with a specific verb and resource. It distinguishes from sibling tools like get_user (single user) and count_users, providing clear purpose.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies usage with filters and pagination but does not explicitly state when to use this tool versus siblings like count_users or search-related alternatives. No exclusions or when-not-to-use guidance is provided.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
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 indicates a read operation but lacks additional behavioral context such as authentication requirements, rate limits, or error handling (e.g., behavior when ID 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.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is concise and front-loaded: the first line gives the core purpose, followed by parameter details in a clear Args section. No 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?
The tool is simple (get by ID), and an output schema exists, so return structure is covered. However, the description does not mention edge cases like missing IDs or handling of realm defaults, leaving minor gaps.
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 adds significant meaning: 'id' is clarified as the database ID (not client_id) and 'realm' is described as optional with a default behavior, which is not evident from the schema alone.
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 gets a specific client by database ID, and distinguishes between 'id' (database ID) and 'client_id', differentiating it from sibling tool 'get_client_by_clientid'.
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 clarifies the key parameter difference (database ID vs client_id) and mentions optional realm, but does not explicitly state when to use this tool over alternatives like 'get_client_by_clientid'.
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 describes a read operation ('Get'), which is safe, but does not disclose any additional behavioral aspects like permissions or rate limits. For a simple get, 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 very concise, with a single-sentence summary followed by clear Args and Returns sections. Every line is informative and no 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?
For a simple get operation, the description covers purpose, parameters, and return type. An output schema exists, and the description mentions the return object. This is complete for the tool's complexity.
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 add meaning. It explains role_name as 'Role name' and realm as 'Target realm (uses default if not specified)', which adds value beyond the schema's field names and types.
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 a specific realm role by name', which is a specific verb and resource. It distinguishes from sibling tools like list_realm_roles, create_realm_role, update_realm_role, delete_realm_role.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides clear guidance: use by role name, with optional realm parameter defaulting to a default realm. It implies when to use but does not explicitly state when not to use or provide alternatives.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
