Tool DescriptionsC

Average 2.5/5 across 12 of 12 tools scored. Lowest: 1.6/5.

Server CoherenceA
Disambiguation3/5

Tools like deadline_risk, early_warning, and evidence_decay have overlapping concerns about deadlines and warnings, though descriptions provide some distinction. Similarly, predict_article, predict_entity, and predict_score all cover predictions but differ in scope. Some ambiguity remains.

Naming Consistency3/5

All names use snake_case, but the naming pattern mixes verb phrases (predict_article, trend_analysis) with noun phrases (deadline_risk, health_check), lacking a consistent verb_noun or noun_verb structure. This inconsistency can confuse an agent.

Tool Count5/5

12 tools is well within the optimal 3-15 range for a specialized predictive analytics server. Each tool appears to serve a distinct function without unnecessary bloat or deficiency.

Completeness4/5

The tool set covers core predictive needs: deadlines, warnings, decay, scores, scenarios, trends, and remediation velocity. Missing are raw data access or configuration tools, but for a read-only prediction server, the surface is reasonably complete.

Available Tools

12 tools
deadline_riskCInspect

Upcoming deadlines with compliance probability %.

ParametersJSON Schema
NameRequiredDescriptionDefault
entity_idNoOptional for entity-specific probability
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description must carry the full behavioral burden. It only states the output nature without disclosing side effects, read-only status, or computational details.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is extremely short and lacks a full sentence structure. While efficient, it could benefit from being a complete thought.

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?

With no output schema or annotations, the description leaves out important context like output fields, probability calculation, and relationship to sibling tools. 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 100% (the only parameter already has a description). The tool description adds no additional meaning beyond what the schema provides, making it baseline adequate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool's output: upcoming deadlines with compliance probability percentage. It uses specific verbs and nouns to convey the function, though it does not differentiate from siblings like risk_forecast.

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 like early_warning or risk_forecast. The parameter hint is minimal and does not clarify usage context.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

early_warningCInspect

Critical warnings: evidence expiry, score prediction, DORA deadline.

ParametersJSON Schema
NameRequiredDescriptionDefault
entity_idNo
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description bears full burden. It does not disclose whether the tool is read-only, what happens when invoked, or behavioral traits beyond listing warning categories.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is very short but lacks a full sentence structure and essential verbs, reducing clarity despite brevity.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

No output schema exists, yet the description does not explain what the tool returns or how the entity_id parameter affects output. The list of warning types is insufficient for complete understanding.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters1/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0% and the description does not mention the entity_id parameter, leaving its role and usage completely unexplained.

Purpose3/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description mentions warning types (evidence expiry, score prediction, DORA deadline) but lacks a clear verb-resource action. It does not distinguish itself from siblings like deadline_risk or evidence_decay.

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 provides no context about prerequisites or exclusions.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

evidence_decayCInspect

Evidence expiry timeline: what expires when, status per evidence.

ParametersJSON Schema
NameRequiredDescriptionDefault
entity_idNo
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 the tool returns expiry timeline and status, but does not clarify if it reads data only, required permissions, or how 'evidence' is defined. This is insufficient for a safe agent invocation.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness2/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single short sentence, but it lacks necessary detail. It is under-specified rather than concise, missing key information that would justify its brevity.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness1/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given low schema coverage, no output schema, and no annotations, the description is severely incomplete. It fails to explain the return structure, parameter usage, or behavioral traits, leaving the agent with minimal actionable information.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters1/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema has one string parameter 'entity_id' with 0% schema coverage. The description does not mention the parameter at all, leaving its purpose unclear. No value is added beyond the raw schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose3/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description gives a general idea of showing evidence expiry timeline and status, but it's vague and does not clearly distinguish from sibling tools like deadline_risk or early_warning. The verb 'expires' is implied but not explicitly stated as a query 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?

No explicit guidance on when to use this tool versus alternatives. The description does not mention prerequisites, when not to use, or suggest related tools. Usage is only implied by the name and brief description.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

health_checkCInspect

Server status.

ParametersJSON Schema
NameRequiredDescriptionDefault

No parameters

Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations provided, so description carries full burden. 'Server status' is too brief; it does not disclose return format, side effects, or safety profile. Agent cannot infer if this is a read-only check.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Extremely concise (two words), but under-specified. Not every word earns its place; more detail would improve 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?

With no output schema and minimal description, the tool lacks completeness. Agent has insufficient information to understand what the tool returns or how to interpret results.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

No parameters exist, so schema coverage is 100%. Description does not need to explain parameters, but could note absence for clarity. This is acceptable.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose3/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description 'Server status' is vague but suggests a health check. However, it does not distinguish from sibling 'ping', which likely tests connectivity. Agent may confuse the two.

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 like 'ping' or 'early_warning'. The context implies use for overall server health, but not explicit.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

pingBInspect

Connectivity test.

ParametersJSON Schema
NameRequiredDescriptionDefault

No parameters

Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries full burden. 'Connectivity test' implies a read-only check but does not explicitly state side effects, return format, or that it only tests network reachability.

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?

Extremely concise at two words. For a simple tool, this is efficient and front-loaded, though slightly lacking in structure for more complex expectations.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's simplicity (no parameters, no output schema), the description is sufficiently complete to convey its purpose. Additional context about expected outcomes is minimal but not critical.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

No parameters exist; schema coverage is 100%. Baseline is 4 for zero parameters, as the description adds no parameter info but none is needed.

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 'Connectivity test' clearly states the tool's purpose with a specific verb and resource. It distinguishes from sibling tools like 'health_check' which likely covers broader system health.

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 like 'health_check'. The description implies basic diagnostic use but does not specify scenarios or exclusions.

predict_articleCInspect

Predict status of a specific DORA article in N days.

ParametersJSON Schema
NameRequiredDescriptionDefault
articleNoe.g. Art. 28
entity_idNo
horizon_daysNo
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 says 'predict', which implies a read operation but does not confirm safety, side effects, or other behavioral traits. No details on data impact, rate limits, or authentication are provided.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is very concise at 7 words, but this brevity comes at the cost of completeness. It lacks structured information like parameter details or usage examples, making it minimally acceptable.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The description is too brief given the tool's complexity (3 params, no output schema, no annotations). It does not explain what 'status' means, the output format, or how the prediction works, 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.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema has 3 parameters but description only implicitly covers 'article' and 'horizon_days' as 'N days', while 'entity_id' is omitted. Schema description coverage is low (33%), and the description does not compensate by explaining formats, constraints, or relationships beyond the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states it predicts the status of a DORA article, using a specific verb and resource. It distinguishes from siblings like predict_entity and predict_score by focusing on articles, and hints at a temporal horizon with 'in N days'. However, 'status' and 'DORA article' could be clearer for general understanding.

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 like predict_entity or deadline_risk. No prerequisites, exclusions, or contextual cues are provided, leaving the agent to infer usage.

predict_entityCInspect

Full predictive risk profile: score trajectory, degradation timeline, risk level.

ParametersJSON Schema
NameRequiredDescriptionDefault
entity_idNo
horizon_daysNoPrediction horizon (default: 30)
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description bears full responsibility for behavioral disclosure. It only states outputs in general terms ('risk profile') without detailing behaviors such as data requirements, computational cost, or handling of invalid inputs.

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 a single concise sentence that front-loads the key purpose ('Full predictive risk profile'). It is appropriately brief but could benefit from slight expansion to cover key aspects without becoming 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 presence of many sibling tools and the lack of an output schema, the description is insufficiently complete. It does not explain when this tool is preferable, nor does it outline the output structure, leaving the agent with an incomplete understanding.

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 does not add meaning to the input schema parameters. The schema has 50% coverage (horizon_days described, entity_id not), but the description does not explain entity_id or the role of horizon_days beyond what the schema provides.

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 it provides a 'full predictive risk profile' including specific elements (score trajectory, degradation timeline, risk level), indicating what the tool does. However, it does not explicitly distinguish itself from sibling tools like 'risk_forecast' or 'deadline_risk', lacking sibling differentiation.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

predict_scoreCInspect

Score trajectory: current, 7d, 14d, 30d, 60d, 90d with trend.

ParametersJSON Schema
NameRequiredDescriptionDefault
entity_idNo
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description must disclose behavioral traits, but it only lists time intervals and mentions a trend. It does not state whether the operation is read-only, requires authentication, or how the trend is computed, leaving significant gaps.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single sentence that efficiently lists the time points and trend indicator. It is concise and front-loaded, with no wasted words, but could be restructured to include parameter context.

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 simplicity (one parameter, no output schema), the description is insufficient. It does not explain what score is predicted, the entity type, or the output format, making it hard for an agent to decide if this tool is appropriate.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters1/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema includes an 'entity_id' parameter with no description (0% schema coverage), and the description fails to mention or explain this parameter. No additional meaning is added beyond the schema field.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose3/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description indicates the tool provides a score trajectory with specific time points (current, 7d, ..., 90d) and a trend, giving a clear verb and resource. However, it does not specify what 'score' refers to (e.g., risk score, quality score), and the distinction from sibling tools like predict_entity or trend_analysis is unclear.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is provided on when to use this tool versus alternatives such as predict_article or trend_analysis. The description lacks context for appropriate usage scenarios or exclusions.

ParametersJSON Schema
NameRequiredDescriptionDefault
entity_idNo
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries full burden. It mentions the outputs (average close time, velocity rating) which implies a read-only analytical tool, but does not explicitly state side effects, permissions, or that no data is modified.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single sentence that directly conveys purpose and outputs without superfluous words. It is appropriately front-loaded.

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?

Without an output schema, the description should specify the structure and formatting of the returned data. It only gives vague terms ('average close time, velocity rating') and ignores the parameter's role, leaving the agent with incomplete information.

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 input schema has one parameter (entity_id) with no description and 0% schema coverage. The description does not explain what entity_id represents or how it filters results, failing to add value beyond the bare schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool measures 'how fast findings are being resolved' and provides output examples like 'average close time, velocity rating'. It distinguishes from siblings such as deadline_risk and early_warning which likely focus on different aspects.

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 alternative tools like deadline_risk or trend_analysis. There is no mention of prerequisites or typical use cases.

ParametersJSON Schema
NameRequiredDescriptionDefault
entity_idNo
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries full burden. It does not disclose whether the operation is read-only, what side effects exist, or the format of the output. Only the ordering ('sorted by urgency') is mentioned, which is insufficient for safe invocation.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness2/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is extremely short (one sentence), but this is under-specification rather than conciseness. It omits critical information that should be present, such as parameter behavior and return 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?

Given the lack of annotations and output schema, the description is not complete. It does not explain what 'degrade' means, the time scope, or how to interpret the urgency sort. The presence of many sibling tools amplifies the need for more context.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters1/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema has one optional parameter 'entity_id' with no description. Schema description coverage is 0%, yet the description does not mention the parameter at all, leaving its meaning and effect entirely unclear.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose3/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description asks 'Which articles will degrade first?' and states 'Sorted by urgency.', which implies the tool forecasts risk for articles and returns them ordered by urgency. However, it lacks an explicit verb like 'List' or 'Get', and does not distinguish from siblings such as 'predict_article' or 'deadline_risk'.

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?

entity_idNo
Behavior1/5

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 tool is read-only, what it returns, or if it has side effects. The agent gets no insight into the tool's behavior beyond the enum list.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is extremely short (one line). While concise, it fails to convey essential information, making it more under-specified than efficiently brief.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness1/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given no output schema, no annotations, and low schema coverage (33%), the description is completely inadequate. It does not explain the tool's purpose, behavior, or how to use its three parameters.

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 33% (only 'scenario' has a description). The description lists the scenario options, which adds minimal value since the schema already documents them. It does not explain 'days' or 'entity_id'.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose2/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description is 'What-if: no_testing, cloud_outage_30d, no_training, policy_expired, data_breach.' It only lists scenario names without a clear verb-resource combination. The name 'scenario_forecast' suggests prediction, but the description does not explicitly state what the tool does (e.g., forecast impact of a scenario).

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines1/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, and the description does not disclose behavioral traits such as whether the tool is read-only, what data it returns, or side effects. It only says 'Historical trend,' which implies a read operation but does not confirm safety.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is extremely short, consisting of a few words. While concise, it sacrifices needed detail; however, it front-loads the core purpose.

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 no annotations, no output schema, and only 1 parameter with 0% schema coverage, the description fails to provide sufficient context for an agent to use the tool correctly. It leaves key questions unanswered (e.g., output format, parameter constraints).

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters1/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema has one optional parameter `entity_id` with no description, and schema description coverage is 0%. The description does not explain the parameter, its purpose, expected format, or how it affects the results.

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?
