Hive Escrow

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

With no annotations, the description should cover behavioral details. It only mentions state validity, but does not disclose side effects (e.g., whether cancellation is irreversible), permission requirements, or rate limits. This is minimal transparency for a mutation 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 extremely concise: two short sentences with no wasted words. It front-loads the action and adds necessary state constraint in the second sentence. Every sentence 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 tool's stateful nature and the presence of sibling tools, the description lacks important context such as return behavior (e.g., success/failure indicators), prerequisites (e.g., escrow ownership), and how cancellation interacts with escrow lifecycle. The absence of output schema is not compensated.

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 no meaning to the input schema parameters (escrow_id, reason). With 0% schema coverage, the agent gets no guidance on what 'reason' signifies or format requirements, leaving the agent to infer from parameter names only.

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 'Cancel an escrow' with a specific verb and resource. It distinguishes from sibling tools (create, fund, get status, release) by indicating a distinct operation, and adds state condition details.

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 limits usage to specific states ('created (unfunded) or funded (payer-initiated refund queue) states'), providing clear context. However, it does not mention when not to use it or suggest alternatives like get_escrow_status for checking state.

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?

With no annotations, the description partially covers behavior: it returns escrow_id and x402 funding challenge. However, it omits details about mutability, authorization needs, or side effects beyond creation.

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?

Single sentence, no filler, directly states purpose and key output.

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?

Mentions return values but no output schema. For a 7-parameter tool, missing details on error conditions or full output shape. 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 57% (4 of 7 parameters have descriptions). The description adds no additional meaning beyond the schema; does not explain enums, defaults, or constraints like expires_in_seconds.

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 action (Create), resource (A2A escrow record), and context (Base USDC). The return value is specified, distinguishing it from sibling tools like cancel_escrow or fund_escrow.

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 vs alternatives (e.g., funding or cancelling). Does not specify prerequisites or scenarios that warrant creation.

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?

With no annotations, the description carries full burden. It discloses behavioral traits like USDC settlement via x402 on specified chains, and importantly notes 'Backend pending (Q3 2026)' indicating current incomplete implementation.

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 front-load the primary action. Every word is informative 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?

For a simple funding tool without an output schema, the description provides sufficient context about settlement chains and backend status, though details on expected responses or side effects could enhance completeness.

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 both parameters. The description adds meaningful context: escrow_id is from open_escrow, tx_hash is the on-chain funding hash, enriching what the schema provides.

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 'Fund' and the resource 'open escrow' via a specific method (submitting on-chain transaction hash). It distinguishes itself from sibling tools like open_escrow, release, and dispute.

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 when an escrow is open and a funding transaction hash is available. It provides clear context but does not explicitly state when not to use or mention 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?

Without annotations, the description offers minimal behavioral insight beyond being a read operation. It does not disclose error responses, authorization needs, or side effects.

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

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

The description is a single sentence with no superfluous words, though it could benefit from slight expansion without losing conciseness.

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 no output schema, the description should detail the returned state and metadata. It only offers vague terms, leaving the agent without enough context to interpret results.

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 single parameter (escrow_id) is simply mentioned as 'by ID' with no additional explanation of format, constraints, or source. Given 0% schema description coverage, this is insufficient.

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 identifies the action ('Retrieve') and resource ('current state and metadata for an escrow by ID'), differentiating it from sibling tools that are write operations (create, fund, cancel, release).

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, nor any prerequisites or conditions for invoking 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?

No annotations provided, so description must cover behavioral traits. It mentions a 50 bps fee deduction, but lacks details on state changes (e.g., escrow consumed?), success/failure conditions, authorization requirements, or transaction finality. 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.

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

Two sentences, concise and front-loaded. Every word provides useful information without 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?

For a financial tool involving fees, the description is too minimal. No output schema, so hints about return value or success indication are missing. No mention of prerequisites (e.g., escrow must be funded) or consequences (e.g., cannot be released again). Leaves many questions unanswered.

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 50% (only payee_address has a description). The description adds 'net payout' nuance but does not explain escrow_id. It relies on parameter names but doesn't compensate for the missing schema description of escrow_id.

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 releases escrowed USDC to a payee and mentions fee deduction. Verb 'release' and resource 'escrowed USDC' is specific. Distinguishes from siblings like cancel_escrow and fund_escrow.

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 alternatives. For a financial action, prerequisites (e.g., escrow must be funded) and conditions are missing. Sibling tools exist but no comparative context.

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