Hive DePIN

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

No annotations are present, so the description carries the full burden. It discloses the match fee (0.15%) and supports 22 metadata fields, which is useful context, but it does not disclose that this is a write operation (despite the name), what side effects occur, whether it requires specific authorization, or what the response looks like. The behavior is under-specified for a creation tool.

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 with no fluff. It front-loads the main purpose and adds fee/count details efficiently. The only structural issue is the ambiguous 'List' verb, which slightly reduces clarity, but the description is still concise and well-organized.

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 12 parameters, 6 required, and no output schema or annotations, the description is insufficiently complete. It does not state what 'create listing' means operationally, does not mention whether the listing is immediately active or pending approval, does not describe the return value, and does not reference the required fields. The fee and field count are nice, but the high complexity demands more context than provided.

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 adds some semantic value by listing example capacity types (storage TB, compute cores, GPU VRAM, bandwidth Mbps) that map to schema fields like capacity_gb, vram_gb, and throughput_mbps. However, it does not explain parameters like unit_label, payout_address, or operator_did beyond the schema. Overall, it adds marginal value but not enough to exceed the 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 states the tool lists physical infrastructure capacity, which is a specific verb+resource, but the verb 'list' is ambiguous—it could mean 'create a listing' or 'display listings.' Given the tool name includes 'create' and siblings include 'depin_list_providers,' the description does not clearly distinguish this as a creation tool. The mention of metadata fields and match fee hints at creation but doesn't explicitly say so.

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 the siblings (depin_get_match_fee, depin_list_providers). The description does not mention alternatives, exclusions, or prerequisites. Without explicit when-to-use guidance, the agent must infer the purpose from the name alone.

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

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

With no annotations, the description carries the transparency burden. It discloses that the tool returns the fee alongside settlement currencies and chains, and the word 'currently' signals the fee may change. It does not discuss authentication or rate limits, but these are less critical for a parameterless read 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 two concise sentences, front-loading the key action and fee value. No filler or redundant information is present.

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 zero-parameter getter with no output schema, the description adequately explains what the tool returns and the current fee. It is complete for the tool's simplicity.

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 tool has zero parameters, so the schema provides no semantic load. The description appropriately focuses on the return value instead, meeting the baseline for parameterless tools.

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 gets the current DePIN marketplace match fee, providing a specific verb and resource. It also distinguishes itself from siblings like depin_create_listing and depin_list_providers by focusing on a read-only fee query.

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 use case: when an agent needs the current match fee and associated settlement currencies/chains. It does not explicitly mention alternatives or exclusions, but the context is clear for a simple getter.

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 the full burden. It notes 'No auth required' but fails to mention pagination, return format, or read-only nature. More critically, it mentions 'capacity' as a filter option that does not exist in the input schema, which is misleading to the agent.

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, readable sentence that front-loads the purpose and lists filters compactly. The 'capacity' mention is extraneous and not schema-backed, so it is slightly less concise than it could be.

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 list tool with full schema coverage, the description is adequate. However, with no output schema, it might be expected to mention return values or pagination. The capacity discrepancy also creates a completeness gap. Overall, it's serviceable but not thorough.

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% (both parameters documented), so the baseline is 3. The description repeats the category list and region example, adding little beyond the schema. It also introduces a non-existent 'capacity' parameter, which reduces its 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 clearly states 'List DePIN provider listings' with a specific verb and resource, distinguishing it from sibling tools like depin_create_listing (write) and depin_get_match_fee (fee lookup). The filter options are enumerated, making the tool's purpose 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?

The description implies usage for browsing providers with optional filters and notes 'No auth required', but it does not explicitly state when to use this tool vs alternatives or provide exclusions. The sibling tools are clearly different, but the guidance is only implicit.

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