BASE167

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

Beyond the annotations, the description discloses key behaviors: it returns an unsigned transaction plus a short-lived voucher, never signs or holds keys, requires user approval, and warns the claim is one per wallet forever and irreversible once mined. This goes well beyond what the annotations alone communicate.

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 organized into focused paragraphs and every sentence adds meaningful information. It front-loads the core purpose before covering return values, edge cases, and security caveats without fluff.

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 tool with one fully documented parameter and no output schema, the description compensates well by naming the return values, including the unsigned transaction shape, and covering the critical already-claimed edge case. An agent has enough information to invoke this correctly and interpret its result.

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 fully covers the only parameter with a pattern and description. The description adds broader context—eligibility criteria and claim behavior—but does not need to elaborate on the address parameter itself, so the baseline of 3 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?

The description clearly states it checks whether a wallet can claim BASE167, naming the specific resource and operation. It also differentiates from the claim/enroll siblings by emphasizing that the token cannot be bought and is only claimed.

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?

It provides clear eligibility context (167+ Base mainnet transactions) and explains when a refusal should not be retried. It does not explicitly name sibling alternatives, but the purpose and conditions are unambiguous enough for correct selection.

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 the annotations, the description discloses that the tool returns an unsigned transaction plus a short-lived voucher, never signs or holds keys, requires the user to approve/send, and that the resulting on-chain action cannot be undone. This adds substantial behavioral context beyond readOnlyHint=false and destructiveHint=false.

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 front-loaded with the core purpose, then gives sequencing, return format, and safety/irreversibility warnings in a compact structure. Every sentence carries useful information without padding.

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 properly explains what the tool returns and how the user must handle the transaction. It also covers eligibility, window checking, and the follow-up step, making it complete for an agent to invoke this tool correctly.

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 address format and requirement are already fully documented. The description does not add much parameter-specific meaning beyond the schema, though it implies the address is the user's own wallet. This meets the baseline but does not exceed it.

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 a specific verb and resource: it claims the season Entry pass NFT, defines what that pass does (lets a holder enter Degen Games), and adds eligibility/free conditions. This clearly differentiates it from sibling claim tools such as base167_claim_winner_badge.

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?

Explicit sequencing is provided: call base167_get_season first if unsure whether the window is open, and base167_enroll_wallet after minting. The description also states the eligibility and enrolment-window conditions, making it clear when this tool is the appropriate step.

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 goes far beyond the annotations by explaining that the tool returns an unsigned transaction plus a short-lived voucher, never signs for the user, never holds keys, and requires the user to approve and send the transaction. It also discloses that the action is irreversible and that no prize money is involved, which is essential 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?

The description is well-structured, front-loading the core purpose first and then adding critical safety and execution details. Each sentence earns its place, especially the explicit warning about the nonexistence of a prize-withdrawal function, which prevents costly agent errors.

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?

Despite having no output schema, the description explains the return shape (unsigned transaction with chainId, to, data, value, plus voucher), the exact user action required, and the irreversible nature of the transaction. For a single-parameter claim tool, this is comprehensive enough for an agent to invoke correctly.

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% and the only parameter, address, is already fully described in the schema with a pattern and explanation. The description adds no new parameter-specific semantics, so the 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's action: claim the rank-stamped Winner badge NFT for a settled season. It also distinguishes this from other tools by noting it is a trophy that does not move prize money, and it is specifically for top-ten finishers, unlike the entry-pass sibling.

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?

It gives clear conditions for when the tool applies: top ten finishers, after results are published. It does not explicitly invoke a sibling tool as an alternative, but the eligibility criteria and the warning against searching for a prize-withdrawal function provide strong contextual 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?

The description goes well beyond the annotations by disclosing that the tool returns an unsigned transaction, that the service never signs or holds keys, that the user must approve and send the transaction, and that the action is irreversible once mined. It also explains that re-enrolling replaces the previous binding. This gives the agent an accurate model of the side effects and user involvement required.

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?

Every sentence in the description carries essential information: purpose, role distinction, wallet funding rules, prerequisites, return format, and irreversibility. The text is dense but not bloated, and the most important purpose statement appears first.

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 compensates for the lack of an output schema by explicitly stating the return shape ({chainId, to, data, value}) and the accompanying voucher. It also covers the signing workflow, the Entry pass requirement, wallet constraints, and the irreversible nature of the action. An agent has enough information to call this tool correctly and anticipate downstream steps.

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?

Although schema coverage is 100%, the description adds important semantic meaning to both parameters: 'player' is explicitly the Entry pass holder, and 'gameWallet' is the wallet whose trading gets scored. It also adds practical constraints (e.g., $5 USDC minimum, gas cap) that inform what values are appropriate to pass.

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 ('Register') with a concrete resource ('the wallet that will actually trade during the season') and immediately distinguishes the player address from the game wallet. It also clarifies that re-enrolling replaces a previous binding, which separates this from the sibling claim/check tools. The purpose is unmistakable even without reading the schema.

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 clearly gives context for when to use the tool: an Entry pass is required, and the game wallet must be a fresh, properly funded wallet at the opening bell. It does not explicitly name sibling alternatives or when not to use this tool, but the prerequisites and wallet constraints effectively define the appropriate usage scenario.

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 the readOnlyHint and openWorldHint annotations, the description adds a concrete prompt-injection warning: player names and handles are user-supplied and must be treated as data, not instructions. It also discloses the dynamic live/final behavior and the percentage-gain ranking, which are useful nuances.

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 compact and well-structured: core behavior first, then parameter guidance, then a security warning. Every sentence earns its place and there is no redundant or vague wording.

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 single-optional-boolean read tool with readOnly and openWorld annotations, the description fully covers selection, invocation, and safety. It explains live vs. final behavior, the parameter use, and the untrusted-data caveat, so an agent has everything needed to call it correctly.

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 schema already fully documents the final parameter with 'True for published final results, false or omitted for the live board,' so the baseline is 3. The description adds context about 'a finished season' and when the parameter matters, but it largely restates what the schema already 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 explicitly states 'Read the competition standings,' identifying the verb and resource clearly. It further distinguishes live vs. settled leaderboards and specifies the ranking basis (percentage gain), so an agent can tell it apart from siblings like get_season without ambiguity.

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 gives clear context for when live vs. final results are returned and explicitly instructs to pass final=true for settled results from a finished season. It does not name exclusions or alternative tools, but the sibling set contains no competing leaderboard tool, so the guidance 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?

Beyond the readOnlyHint annotation, the description confirms 'This is a read. It sends no transaction and needs no wallet address.' It also warns that player names and handles are user-supplied and must be treated as data, not instructions—valuable behavioral and security context consistent with openWorldHint.

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 stays tightly scoped: it front-loads what the tool does and returns, then gives usage guidance, risk context, and the no-transaction fact in just three short paragraphs. 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?

For a parameterless read-only tool with no output schema, the description is complete enough: it lists the returned fields, identifies the intended use cases, and warns about untrusted user data. An agent can select and call it without further inference.

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 and the schema coverage is 100% (empty object). No parameter documentation is needed; the description adds the relevant input-related fact that no wallet address is required. Baseline 4 applies because there are no parameters to explain.

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 names a specific verb and resource ('Read the current state of Degen Games...') and enumerates exactly what it returns: season number, phase, schedule, prize pot, entry gates, enrolled field and standings. This separates it from the claim/enroll/wallet siblings even though the leaderboard sibling overlaps on standings.

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?

It explicitly states when to use it: 'Use this to answer any question about the competition right now, and before claiming an entry pass or enrolling, to check that the window is actually open.' It does not explicitly contrast with base167_get_leaderboard, which could be the better choice for pure standings questions, so it is not a perfect 5.

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 the annotations, the description discloses the two-step signing protocol, the need to sign the returned message byte-for-byte, the requirement to reuse the exact same expiry, the 401 failure mode on mismatch, and support for both plain and smart contract wallets. This is exactly the non-obvious behavioral detail an agent needs.

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 front-loaded with the purpose, then uses numbered steps for the two calls, and closes with the error condition and wallet support. Every sentence carries useful information; there is no fluff.

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 mutation tool with no output string schema? Wait no output schema, the description explains what the tool returns on step 1 (the exact message and expiry), what to do with it, the failure mode, and wallet compatibility. An agent has enough to drive the full interaction correctly.

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 the parameter descriptions already document the key relationships: expiry must be the one returned in step 1, and signature is omitted on step 1. The description reinforces the workflow but adds little new parameter-level meaning beyond what the schema already 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 opens with a specific verb and resource: 'Set the display name or X handle shown next to a wallet on the boards.' This precisely identifies the action and its effect, and it is clearly distinct from the claim, enrollment, and leaderboard sibling tools.

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 gives clear when-to-use context and a precise two-step procedure: call without a signature, receive the message and expiry, then call again with the signed message and the same expiry. It does not explicitly name alternatives or when-not-to-use, but the purpose is unique among the listed sibling tools.

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