XDaLa Workflow Builder

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

Annotations indicate mutation (readOnlyHint false) but no destructiveness. Description adds critical context: cancellation only applies to pending offchain state, not chain transactions, which is beyond what annotations provide.

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

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

Two sentences, no redundancy. First sentence defines main purpose, second clarifies boundary. Every word earns its place.

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

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

For a simple cancellation with output schema, description covers key behavioral constraint (non-chain). Could mention idempotency or failure cases, but idempotentHint and schema reduce need.

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

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

Schema description coverage is 100% and both params (secret, operationId) have clear descriptions. Tool description does not add further meaning, so baseline score applies.

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

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

Description clearly states the action (cancel) and resource (pending offchain operation handoff), and explicitly clarifies it does not affect already signed or submitted chain transactions. This distinguishes it from sibling cancellation tools that target specific handoff types.

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

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 the other cancellation tools (e.g., cancel_xdala_bundle_deploy_handoff). Agent must infer based on names alone.

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

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

The description adds that this operation is 'offchain metadata only and never cancels chain transactions,' which is valuable context beyond the annotations (idempotent, non-destructive). It could mention what happens if the handoff is already processed.

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

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

The description is two short sentences, each adding essential information: the core purpose and a key behavioral clarification. No redundant or unnecessary words.

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

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

The description adequately covers the tool's purpose and safety aspects. With an output schema present and low complexity, it is sufficiently complete, though it could explicitly state that the handle must be valid and pending.

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

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

With 100% schema coverage and the schema already describing the 'handle' parameter as opaque and from a previous MCP tool, the description adds no new parameter meaning, meeting the baseline of 3.

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

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

The description clearly states the verb 'cancel' and the resource 'pending XDaLa bundle deploy handoff', distinguishing it from sibling tools like cancel_operation_handoff and cancel_xdala_session_start_handoff.

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

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

The description specifies the tool is for canceling a pending XDaLa bundle deploy handoff, implying its specific scope. However, it does not explicitly mention when not to use it or list alternative cancel tools by name.

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

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

The description claims this is a 'preparation/read-only MCP tool', but the annotations set readOnlyHint=false, indicating it is not read-only. This is a direct contradiction. Additionally, while it says it does not sign/submit/execute/cancel on-chain work, the tool name suggests cancellation of metadata, which is 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.

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

The description is concise: two sentences that convey purpose and behavioral constraints without any redundant or extraneous information.

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

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

Given the tool has one parameter, an output schema, and annotations, the description is relatively complete. However, the contradiction between description and annotations on read-only nature reduces clarity and completeness. It does not explain what cancelling metadata means or what happens to the session.

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

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

Schema coverage is 100% with a detailed description for the 'handle' parameter. The description adds no further semantics beyond the schema, so baseline 3 is appropriate.

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

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

The description clearly states the tool cancels pending xDaLa session start handoff metadata. It distinguishes itself from sibling tools like cancel_operation_handoff and cancel_xdala_bundle_deploy_handoff by specifying 'metadata only' and that it does not perform on-chain work.

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

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

The description implies the tool is for canceling a pending handoff, and the name clarifies the specific handoff type. It does not explicitly state when to use vs alternatives, but the context is clear. Adding prerequisites like needing a handle would improve.

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

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

Annotations indicate it's not read-only, not destructive, and idempotent. The description adds that the MCP never signs or submits transactions and that users execute locally with a browser wallet. This clarifies the offchain nature and user involvement, going beyond annotations. 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.

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

Description is efficient with 5 sentences, front-loading the main purpose and behavior. It is well-structured but could potentially be slightly more concise without losing clarity.

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

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

Given the tool's complexity (9 parameters, nested objects, output schema), the description covers purpose, behavior, and usage guidelines adequately. It does not elaborate on return structure but an output schema exists. The description is sufficient for an agent to decide when to use the tool.

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

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

Schema description coverage is 100%, so the input schema already provides parameter descriptions. The tool description does not add additional semantics for parameters, staying at baseline.

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

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

The description clearly states the verb 'Create', the resource 'offchain human-in-the-loop operation', and the return value 'browser URL'. It also distinguishes itself from similar tools by explicitly stating what it is not for and naming the alternative tool 'create_xdala_session_start_handoff'.

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

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

Provides explicit instructions on when not to use this tool (XDaLa sessions, etc.) and directs to the correct sibling tool, including a fallback instruction if that tool is unavailable. This is exemplary guidance.

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

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

Annotations indicate non-read-only, open world, idempotent, non-destructive. The description adds crucial context: 'The MCP does not sign, submit, or execute transactions' and describes offchain storage under an unguessable handle. This goes beyond annotations to clarify the tool's scope and limitations. No contradictions detected.

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

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

The description is extremely concise: two sentences that cover the core action (store offchain, return URL) and a key behavioral disclaimer (no signing/submitting). Every word is purposeful with no redundancy.

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

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

Given the presence of an output schema (which handles return value details) and annotations, the description is largely complete. It states the key action and limitations. However, it could be improved by mentioning that the bundle should be validated beforehand (siblings like 'validate_xdala_bundle' exist) or by hinting at the output structure.

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

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

Schema description coverage is 100% with each parameter documented. The tool description does not add extra meaning or usage details beyond the schema. Since the schema already provides adequate descriptions, baseline of 3 is appropriate.

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

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

The description clearly states the tool stores a validated bundle offchain and returns an import URL, and explicitly says it does not sign/submit/execute transactions. While specific, it does not explicitly differentiate from other 'create_handoff' siblings like 'create_operation_handoff', but the mention of 'xgr-multi-bundle@1' and 'XDaLa Workbench' provides sufficient specificity.

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

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 such as 'create_operation_handoff' or validation tools. There is no mention of prerequisites (e.g., bundle must be validated first) or exclusions, leaving the agent without context for decision-making.

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

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

The description adds context beyond what annotations provide. For example, it clarifies that 'The MCP does not sign, submit, or execute' and 'xDaLa Workbench performs local signing and calls xgr_validateDataTransfer.' It also explains the return value: 'This tool returns a Workbench xdalaUrl...' This transparency helps the agent understand the tool's behavior. No contradiction with annotations: readOnlyHint=false is consistent with the tool performing a write (store) operation.

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

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

The description is verbose and includes many specific instructions and caveats. While it is front-loaded with the main purpose, it contains repetitive elements (e.g., multiple mentions of 'Use this tool'). Some details could be streamlined without losing clarity, but the length is justified by the complexity of the tool.

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

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

Given the tool's complexity (22 parameters, nested objects, multiple sources) and the presence of an output schema, the description covers most important aspects. It explains the workflow for different source types, what not to do, and what the output contains. It could be improved by a brief summary of output schema fields, but overall it is sufficiently comprehensive.

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

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

With 100% schema description coverage, the schema already documents all parameters. The description adds meaning by explaining usage context for parameters, such as how to derive sessions[] fields from XRC-137 rules: 'derive required payload fields from the XRC-137 payload schema, treat fields with defaults as optional.' It also clarifies that 'entryStepId is not the Workbench Session Start field.' This additional guidance helps the agent use parameters correctly.

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

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

The description clearly states the tool's purpose: 'Prepare and store a read-only xgr-session-start@1 handoff for xDaLa Workbench.' It lists multiple specific use cases (starting from a runtime, bundle deploy result, etc.) and explicitly says when to use it: 'Use this tool whenever the user wants to start, run, launch, execute, queue, or prepare an XDaLa session.' This distinguishes it from sibling tools like create_xdala_bundle_deploy_handoff.

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

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

The description provides extensive guidelines on when and how to use the tool, including steps for deployed workflows: 'For deployed XRC-729 workflows, first inspect the runtime, identify ostcId and the likely entry step...' It also includes explicit don'ts: 'Do not call this tool with guessed payload values.' However, it does not explicitly mention when not to use this tool in favor of alternatives, though sibling tools are listed.

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

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

The description adds 'live mainnet order' hinting at real transactions, but does not disclose consequences (e.g., charges, payment flow). Annotations already indicate non-read-only and non-destructive, but the description adds minimal extra behavioral context.

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

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

A single sentence is concise but lacks structure. It does not front-load critical details beyond the action. Could be improved with structured hints or bullet points.

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

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

Given 8 parameters, a write operation, and mainnet context, the description is too minimal. It does not explain what an order is, post-creation behavior, or how to use the output schema. Annotations provide openWorldHint but no elaboration.

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

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

Schema coverage is 100% with generic descriptions ('Value for the ... parameter'). The tool description does not add any additional meaning beyond the parameter names, so baseline score of 3 is appropriate.

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

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

The description clearly states the verb 'Create', the resource 'live mainnet order for a fixed XGR amount', and distinguishes from the sibling 'create_xgr_purchase_order_by_budget' which likely handles different budget logic.

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

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

No explicit guidance on when to use this tool vs alternatives (e.g., 'create_xgr_purchase_order_by_budget'). No context on prerequisites or when not to use it.

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

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

Beyond annotations (readOnlyHint=false, destructiveHint=false), the description highlights that 'payment may be blocked after exact backend check', adding behavioral context about potential failures. This is useful for the agent to anticipate outcomes.

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

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

The description is a single, front-loaded sentence with no wasted words. It efficiently communicates the core purpose and a key behavioral note.

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

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

With an output schema present (context signal), the description need not explain return values. It covers the main action and a behavioral nuance. Lacks prerequisites or further context, but sufficient for a tool with 9 parameters and rich schema.

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

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

Schema description coverage is 100%, so the baseline is 3. The description does not add additional meaning to any of the 9 parameters beyond what the schema already provides. No parameter-specific guidance.

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

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

The description clearly states it creates a 'conservative USDC/USDT budget order', specifying the action (create), resource (budget order), and constraints (asset types, conservative nature). This distinguishes it from siblings like 'create_xgr_purchase_order' which likely lacks the budget aspect.

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

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

The description implies usage for creating a budget order but does not explicitly state when to use this over alternatives (e.g., create_xgr_purchase_order) or when not to use it. No exclusions or prerequisites are mentioned.

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

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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, so the description adds value by specifying the exact output components (validation gas, branch gas, etc.) beyond what annotations provide. 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.

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

Two concise sentences: first states the action, second lists what is returned. No filler or redundancy.

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

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

With output schema present and annotations covering safety, the description adequately covers purpose and return values. Could add more context on parameter roles, but overall sufficient for a straightforward estimation tool.

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

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

Schema coverage is 100% with descriptions for each parameter, so baseline is 3. Description does not add any additional meaning beyond the schema's parameter descriptions.

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

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

Description clearly states the tool estimates XDaLa/XRC-137 rule gas and lists specific return fields (validation gas, branch gas, grant fees, worst-case totals). It uniquely identifies the tool among siblings (e.g., validate_xdala_rules) by focusing on estimation.

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

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

Description tells the agent to 'use this to estimate' but does not explicitly state when to use this tool versus alternatives like validate_xdala_rules. Usage context is implied but not guided.

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

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

Annotations already provide readOnlyHint, idempotentHint, etc. Description adds minimal context about resolving from Explorer database and optional payload inclusion, which is helpful but not extensive. No contradiction with annotations.

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

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

Two concise sentences with front-loaded usage condition. Every sentence adds value with no wasted words.

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

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

Given the complexity and existence of output schema, description is fairly complete. It could mention that it returns a singleton result based on indexing time, but overall clear.

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

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

Schema description coverage is 100%, so baseline is 3. Description does not add meaningful semantic details beyond the schema's parameter descriptions; it only indirectly references includePayload.

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

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

Description clearly states the tool finds the latest XDaLa session when owner and sessionId are not provided, using specific verb 'resolves' and resource 'newest indexed XDaLa session'. It distinguishes from sibling tools by specifying the condition for use.

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

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

Explicitly says when to use: when user asks for latest session without owner and sessionId. However, it does not explicitly state when not to use or suggest alternatives, though implied.

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

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

Annotations already provide strong behavioral hints (readOnlyHint, openWorldHint, idempotentHint). The description adds 'metadata-assisted search' and 'reuse' context, reinforcing read-only behavior. No contradictions. The description complements the annotations adequately.

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

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

The description is a single, well-structured sentence that front-loads the key purpose. No unnecessary words or repetition. Every part contributes meaning.

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

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

Given the complexity (8 parameters, nested object) and the presence of a similar sibling ('get_unused_xrc137_rules'), the description could be more specific about the relationship with that sibling and what 'metadata-assisted' entails. However, the output schema exists and annotations are rich, so the description is minimally adequate but not comprehensive.

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

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

Schema coverage is 100%, so the baseline is 3. The description uses 'metadata-assisted' to hint at filtering, but does not add significant meaning beyond the schema's parameter descriptions. It does not explain how parameters combine or prioritize them, so marginal value is added.

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

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

The description uses a specific verb ('find'), identifies the resource ('reusable XRC-137 rules'), and specifies the context ('existing owner XRC-137 contracts that could be reused instead of redeployed'). It clearly distinguishes from siblings like 'get_unused_xrc137_rules' by emphasizing search and reuse.

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

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

The description implies when to use this tool: to find existing rules and avoid redeployment. However, it does not explicitly state when not to use it or compare it to the closely related sibling 'get_unused_xrc137_rules'. The context is clear but lacks explicit exclusions.

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

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

Annotations already declare readOnlyHint=true and destructiveHint=false. The description adds behavioral context with 'Read-only discovery' and clarifies that it does not create handoffs, which is useful beyond the annotations. 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.

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

The description consists of two concise sentences with no wasted words. The first sentence immediately states the purpose and scope, and the second provides usage context and a key exclusion. Information is front-loaded and efficient.

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

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

Given the tool's complexity (9 parameters, all well-documented in schema, output schema present) and annotations covering safety, the description is fully adequate. It clearly defines when to use the tool, what it does, and what it does not do, leaving no gaps for an AI agent to misunderstand.

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

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

Schema description coverage is 100%, so each parameter is already described in the schema. The tool description adds no additional parameter meaning beyond what the schema provides. Baseline 3 is appropriate.

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

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

The description clearly states the tool's purpose: 'Read-only discovery of deployed XRC-729 workflows that a given address can start as owner, executor, or wildcard executor.' It specifies the verb (discovery), resource (deployed XRC-729 workflows), and scope (by address). The explicit statement 'This tool does not create session-start handoffs' distinguishes it from sibling tools that create handoffs.

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

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

The description provides explicit usage guidance: 'Use this whenever the user provides an address and asks which sessions/workflows they can start.' It also clarifies what the tool does not do ('This tool does not create session-start handoffs'), but does not explicitly mention alternative tools or when not to use it.

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

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

Annotations already mark it as read-only, open-world, idempotent, and not destructive. The description adds value by specifying it returns 'live' (real-time) data and explicitly listing returned fields (balance, nonce, contract code). No contradictions with annotations.

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

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

The description is two sentences, front-loaded with the purpose, and contains no unnecessary words. Every sentence contributes to understanding.

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

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

Given the tool's simplicity (one parameter, clear purpose, output schema exists), the description is complete. It covers what the tool does, its read-only nature, and what it returns. No additional details are needed.

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

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

The input schema covers all parameter details (address with pattern and description), and schema description coverage is 100%. The description does not add additional semantic meaning beyond what the schema provides, so a baseline score of 3 is appropriate.

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

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

The description clearly states the tool retrieves live EVM account state including balance, nonce, and contract code for an address. It uses a specific verb ('Get') and resource ('account live state'), and distinguishes from sibling tools like get_account_transactions or get_latest_block.

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

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

The description indicates when to use ('for live EVM account state') but does not provide explicit guidance on when not to use it or alternative tools. While the context is clear, no exclusions or comparisons to siblings are given.

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

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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, covering the safety profile. The description adds 'chain-wide Explorer DB' for scope context but does not disclose additional behavioral traits beyond that. Given the robust annotations, the description adds marginal value.

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

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

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

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

The tool has 6 parameters and an output schema (not shown but present). The description does not explain return values, but that is acceptable given the output schema. It covers the core behavior (account lookup, direction scope) sufficient for an agent to understand its role among many sibling tools. Slightly more detail on parameters could elevate it, but it is adequate.

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

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

Schema description coverage is 100%, so baseline is 3. The description does not add any parameter-specific meaning beyond what the schema already provides (e.g., no explanation of 'direction' enum or 'windowHours'). The schema carries the full burden, and the description adds no extra semantic value.

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

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

The description explicitly states 'Read-only chain-wide Explorer DB transaction lookup for one account as sender, recipient, or both.' It includes a specific verb ('lookup'), resource ('transactions for one account'), and scope ('chain-wide' and 'as sender, recipient, or both'), clearly distinguishing it from sibling tools like get_block_transactions.

Given the tool's simplicity (one optional parameter, output schema exists), the description sufficiently enables selection. It could mention that the output is a timeseries (implied by name) or the granularity of data points, but overall it is complete enough.

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

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

The only parameter 'windowHours' has a schema description: 'Value for the window hours parameter.' The tool description repeats this without adding new meaning. Since schema coverage is 100%, the baseline is 3.

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

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

The description clearly states the tool's purpose: retrieving active/concurrent XDaLa sessions over time. It uses specific verb ('get') and resource ('active sessions timeseries'), distinguishing it from sibling tools like 'get_xdala_session_timeseries' which likely covers all sessions.

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

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

The description explicitly instructs when to use this tool ('when the user asks for active/concurrent XDaLa sessions over time'), providing clear context. It does not explicitly state when not to use or list alternatives, but the context is sufficient.

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

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

Annotations already indicate readOnly, openWorld, idempotent, and non-destructive behavior. The description adds minimal behavioral context beyond 'use before...' which hints at a prerequisite, but does not explain what 'authoring rules' are or any potential constraints.

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

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

The description is a single sentence with no wasted words. It is front-loaded and efficient.

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

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

Schema coverage is 100% and the schema already describes the handle parameter as 'Opaque handoff handle returned by a previous XDaLa MCP tool.' The description does not provide additional parameter semantics beyond the schema.

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

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

Clearly states the tool returns stored deploy result, canonical artifact, and audit events for a handoff handle. The verb 'get' and resource 'XDaLa bundle deploy result' are specific and differentiate it from siblings like get_xdala_bundle_deploy_handoff.

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

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

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

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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint, and destructiveHint false. The description adds that the tool returns values that occurred, but no additional behavioral traits (e.g., aggregation, sorting) are disclosed. For a read-only tool with strong annotations, this is adequate but not enhanced.

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

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

A single, front-loaded sentence with examples. No unnecessary words, highly efficient.

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

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

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

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

No parameters exist, so schema coverage is 100% by default. Description does not need to explain parameters. Baseline for zero parameters is 4.

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

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

Description clearly uses verb 'retrieve' and resource 'XGR core protocol addresses', and distinguishes itself by referencing the specific RPC method 'xgr_getCoreAddrs'. Among many siblings, this tool's purpose is unambiguous.

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

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

Description implies usage context ('Use this to retrieve...') but does not explicitly state when to use versus alternatives or when not to use. Lacks guidance on preconditions or exclusions.

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

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

Annotations already declare readOnlyHint=true, openWorldHint=true, idempotentHint=true, destructiveHint=false, so the agent knows this is a safe read operation. The description adds minor context ('canonical Markdown documentation') but does not elaborate on error handling or exact behavior beyond what the schema provides.

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

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

The description is a single sentence (10 words), front-loaded with the verb 'retrieve', and contains no unnecessary information. Every word earns its place.

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

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

Given the simple parameter (enum), annotations covering safety, and presence of an output schema, the description is mostly complete. It could optionally clarify that the returned documentation corresponds to the specified topic, but the current version is sufficient.

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

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

The description adds meaning beyond the schema: it specifies the output is Markdown documentation and clarifies that the topic is XGR/XDaLa-related. Schema coverage is 100% with an enum, but the schema description for 'topic' is tautological ('Value for the topic parameter'), so the tool description compensates.

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

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

The description clearly states the action ('retrieve') and resource ('canonical Markdown documentation for an XGR/XDaLa topic'). It distinguishes from sibling tools like 'list_xgr_docs' which lists all topics, and other get_ tools that retrieve specific standards or references.

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

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 explicit 'when to use' or 'when not to use' is given, and no mention of related sibling tools.

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

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

Annotations already declare readOnlyHint, openWorldHint, idempotentHint, and destructiveHint=false, covering safety. The description adds minimal behavioral context beyond stating it retrieves documentation, missing details like whether results are cached, size limits, or response format.

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

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

The description is a single, clear sentence with no extraneous words. It is front-loaded with the key action and resource.

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

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

Given the tool has no parameters and annotations provide safety info, the description is complete for a simple retrieval tool. The output schema exists but is not shown; the description does not need to explain return values since the output schema handles that.

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

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

The input schema has no parameters, so the description does not need to add parameter information. The schema coverage is 100% (empty), and the description is sufficient.

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

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

The description clearly states the action ('retrieve') and the specific resource ('canonical xgr-multi-bundle@1 Markdown documentation'), distinguishing it from siblings like 'get_xgr_multibundle_schema' and 'get_xgr_doc'.

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

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_xgr_multibundle_schema' or 'list_xgr_docs'). The description does not mention any prerequisites or situations 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.

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

Annotations declare readOnlyHint=true, openWorldHint=true, idempotentHint=true, and destructiveHint=false, which clearly indicate this is a safe, read-only, idempotent operation. The description 'Retrieve' is consistent but adds no behavioral context beyond the annotations, such as caching behavior or semantic meaning of 'canonical'.

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

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

The description is a single, brief sentence that conveys the core purpose. It is not verbose, but could potentially include a bit more context (e.g., what the schema is used for) without becoming overly long.

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

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

Given the tool has no parameters and annotations provide safety guarantees, the description adequately states the purpose. However, it does not explain how this schema relates to other XGR tools or what 'canonical' implies, which could be helpful for an agent.

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

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

The input schema has no properties, so there are no parameters to document. Schema description coverage is 100% (trivially). The description does not need to add parameter info. Baseline for 0 parameters is 4.

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

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

The description 'Retrieve canonical XGR MultiBundle schema' clearly states the action (retrieve) and the specific resource (canonical XGR MultiBundle schema). It is distinct from sibling tools like 'get_xgr_multibundle_reference' or 'get_xgr_standard_schema', which have different purposes.

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

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 such as 'get_xgr_multibundle_reference' or 'get_xgr_standard_schema'. There is no mention of prerequisites, typical use cases, or when not to use it.

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

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

Annotations already cover readOnlyHint, openWorldHint, idempotentHint, destructiveHint. Description adds minimal behavioral info (returns metadata and links) but no contradictions. With strong annotations, a 3 is appropriate.

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

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

Three sentences, front-loaded with usage guidance, no fluff. Every sentence adds value.

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

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

Given the complexity and existence of output schema, the description adequately covers scenarios, differentiates from sibling, and notes return type. Annotations provide safety profile. Complete.

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

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

No parameters in input schema (0 params). Baseline 4 as per rules. Description does not need to explain parameters since there are none.

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

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

The description clearly states the tool returns canonical project metadata and links about XGR.Network, XGRChain, XDaLa, etc. It uses the verb 'get' and specifies the resource, distinguishing it from siblings like get_chain_status.

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

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

Explicitly lists when to use (user asks what XGR.Network is, requests official URLs) and when not to (use get_chain_status for live state). Provides clear context and alternatives.

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

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

Annotations already declare readOnlyHint, idempotentHint, etc. The description adds no new behavioral context beyond stating the resource. No contradiction, but minimal added value.

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

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

Description is a single, clear sentence with no wasted words. Perfectly concise and front-loaded.

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

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

Given zero parameters, rich annotations, and an output schema, the description is sufficient. It could mention output nature, but overall complete for a simple getter.

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

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

The input schema has zero parameters with 100% schema description coverage. The description does not need to add param info. Baseline is 4, and no further details required.

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

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

The description clearly states the tool reads available mainnet purchase options. The name and description align, distinguishing it from siblings like 'get_xgr_circulating_supply' or 'quote_xgr_purchase'.

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

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

The description is adequate but provides no explicit guidance on when to use this tool versus alternatives. For a simple read-only tool, this is acceptable but lacks proactive direction.

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

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

Annotations already indicate read-only, idempotent, non-destructive. The description adds the term 'canonical' and 'Workbench' but doesn't disclose additional behaviors (e.g., caching, schema versioning). It is adequate given the annotations.

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

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

The description is a single sentence that is front-loaded with the action and resource. No extraneous information. Every word earns its place.

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

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

Given no parameters and an output schema that likely describes the return value, the description is complete. It specifies exactly what schema is retrieved. No additional context needed.

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

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

There are no parameters, so schema_description_coverage is 100%. The description adds no extra parameter detail, which is acceptable. Baseline score of 3 applies.

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