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

With no annotations, the description carries the full burden and does so: it declares cost ('Free'), the on-chain escrow release, the start of reconstruction, downstream availability of the capture/model, and irreversibility. These are exactly the side-effect and reversal facts an agent needs before invoking a destructive write.

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?

Four short clauses, front-loaded with cost and action, with the irreversible warning last where it lands. The telemetry-style fragment 'Free.' earns its place, though a few fragments stack up.

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?

Covers outcome and where results surface (vangrid_bounty_status), which is important since there is no output schema. It omits any identifier-sourcing guidance, which is the one remaining gap for a two-required-param mutation.

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 0% and neither bounty_id nor submission_id is described in the text beyond loose contextual references ('one submission on an open bounty'). The description does not tell the agent where these identifiers come from or their format, so it fails to compensate for the schema gap.

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?

States a specific verb and resource ('Accept one submission') and scopes it to 'an open bounty you posted,' which is enough to distinguish it from vangrid_post_bounty and vangrid_cancel_bounty without opening a 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 precondition is clear: the bounty must be open and must be one you posted, and only one submission is accepted per call. It does not name an explicit alternative or exclusion, but the implied workflow with vangrid_post_bounty and vangrid_bounty_status is easy to infer.

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, and it does well: it discloses cost ('Free'), the complete status lifecycle (paid, open, accepting, accepted, cancelled, expired_refunded, failed), the 15-minute validity of preview video URLs, and that full capture/3D model links are only exposed post-accept. Gaps remain around authorization (it implies ownership but doesn't state it as a requirement) and pagination/limits on the submissions list.

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, front-loaded with the free/summary fact and the core resource, then a conditional detail about post-accept links. The parenthetical status enumeration is dense but earns its place by defining the return vocabulary; no filler sentences.

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 and no annotations, the description sensibly describes the return payload itself: status values, on-chain id, board link, submissions with preview URLs and quality status, plus the post-accept additions. What is missing is pagination/limits for submissions and any error behavior for an invalid or unauthorized bounty_id.

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 0% and bounty_id has no schema description. The description only indirectly clarifies the parameter by scoping it to 'a bounty you posted,' which implies the id must belong to the caller but gives no format or source (e.g., returned by vangrid_post_bounty). This partially compensates for the coverage gap without fully closing 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?

States a concrete verb and resource: returns the status of a bounty the caller posted, along with its on-chain id, board link, and submissions received. The read-only status framing is distinguishable from mutating siblings like vangrid_post_bounty, vangrid_accept_submission, and vangrid_cancel_bounty, though none are named explicitly.

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?

Usage is implied rather than stated: 'a bounty you posted' scopes it to your own bounties, and the note that full capture/3D model links 'appear on the accepted submission' after accept tells the agent when extra data becomes available. There is no explicit when-to-use versus-alternatives guidance or stated prerequisites.

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 and does disclose meaningful behavior: the operation is free, the escrow is withdrawn on chain, and USDC is returned to the paying wallet. It does not state irreversibility, failure modes, or ownership/permission requirements beyond the implied 'you posted', which are notable gaps for a destructive on-chain action.

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 short sentences with the cost fact front-loaded and the precondition before the on-chain effect. Every sentence carries information; the one-word 'Free.' opener is terse but purposeful.

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 one-parameter mutation tool with no output schema, the description covers the precondition and the financial consequence well enough to call it correctly. Missing permission/auth detail and the post-cancellation state keep it from being fully 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?

Schema description coverage is 0% and the description says nothing about bounty_id (format, where to obtain it). The single parameter is self-explanatory from its name, so the cost is small, but the description fails to compensate for the coverage gap as the low-coverage rule requires.

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?

States a specific verb and resource ('cancel a bounty') plus the two conditions that make it valid: you posted it and it is still open. This cleanly separates it from siblings like vangrid_post_bounty and vangrid_accept_submission without needing the schemas.

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 preconditions ('you posted', 'still open') tell the agent exactly when this tool applies, which is the core of usage guidance. It stops short of naming an alternative for the case where those preconditions fail (e.g., check vangrid_bounty_status first), so it is clear but not exhaustive.

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 and does well: it discloses paid-per-call pricing in USDC on Base (eip155:8453) or Arc (eip155:5042) at ~$0.01, the coarse geohash-6 location precision, the EAS attestation anchoring, and hard area limits. It omits any note on rate limits or failure modes, which keeps it short of a 5.

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 dense sentences that are front-loaded on what the tool returns, followed by cost and area constraints. The pricing sentence packs two chains, addresses and a cost figure, but every element is load-bearing for a paid tool, so little is wasted.

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 correctly spends space enumerating return fields (coarse location, capture time, EAS attestation), and it covers payment and area validity. It leaves pagination/limit semantics and error behavior to the schema, which is acceptable for this complexity level.

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, but the description adds constraints the schema does not encode: the bbox limit of 100 km² and the max radius of 5000 m tied to Point geometry. It still doesn't clarify defaults for from/to or limit behavior 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?

States a specific verb ('Find') and resource ('anchored ground-level captures') bounded by an area and time window, so the agent knows exactly what comes back. It does not name a sibling like vangrid_observation or vangrid_verify_provenance, so differentiation must be inferred from the noun phrase alone.

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 area/time framing implies when the tool is appropriate (spatial coverage inspection), but there is no explicit when-to-use/when-not-to-use guidance and no routing to the sibling tools that fetch a single observation or verify provenance. Usage is left to inference.

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 and does disclose the non-obvious behavior: this is a paid read, priced at roughly $0.005 USDC, payable on Base (eip155:8453) or Arc (eip155:5042). It also names the data returned and where attestation lives. It omits failure modes (unknown hash, unpaid call) but covers the critical commercial/payment traits.

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, tightly packed, front-loaded with what is fetched and keyed on before moving to payment details. No filler.

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 and no annotations, the description compensates by enumerating the returned fields (coarse location, capture time, EAS attestation) and the payment rails. For a one-parameter read tool this is close to complete; only error/edge-case behavior is left unspecified.

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 the single id parameter documented, so the baseline is 3; the description adds real value by clarifying the hash may be supplied with or without a 0x prefix, a format detail the schema does not state.

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?

States a specific verb (fetch), resource (one anchored capture), identifier (sha256) and the returned content (location, capture time, EAS attestation on Base). However, it does not distinguish itself from the sibling vangrid_verify_provenance, which plausibly also operates on a capture hash, so an agent still has to infer the boundary between the two.

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?

Usage is implied by the purpose and the cost note ('paid per call... about $0.005') implicitly warns the agent to use it deliberately, but there is no explicit when-to-use vs. when-to-use-an-alternative guidance and no mention of verify_provenance or coverage_query as 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?

With no annotations, the description carries the full burden and does so well: it discloses immediate USDC payment on Base or Arc mainnet, refund-on-cancel/deadline behavior, server-quoted amount limits (default 50–5000), and that the bounty token is stored locally so later tools only need bounty_id. This is exactly the behavioral context an agent needs before committing funds.

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?

Front-loaded with the core action and payment consequence, then the workflow, then constraints. It is dense and runs as one long paragraph, but nearly every clause earns its place; a break into workflow vs. constraints would slightly improve scanability.

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?

There is no output schema, and the description implies the return contains a bounty_id but does not state the response shape explicitly. Otherwise it fully covers the action, cost, refund path, and follow-up tools, making it complete enough for correct invocation.

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 already 100%, so the schema documents field constraints. The description still adds value the schema lacks: the server-quoted amount band (50–5000, overriding the schema's misleading minimum of 1) and the deadline default of 7 days, which the schema does not state. That is meaningful supplementation 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?

States a specific verb+resource ('Commission a ground-level 3D capture of a real place') and immediately frames the mechanism as posting to a bounty board, which cleanly distinguishes it from siblings like vangrid_coverage_query and vangrid_verify_provenance. An agent can identify this as the create-a-bounty entry point without opening 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?

Explicitly routes the agent through the lifecycle and names the sibling tools for each step: review with vangrid_bounty_status, accept with vangrid_accept_submission, and the implicit cancel path via vangrid_cancel_bounty. It also states the triggering condition for refunds (no acceptance by deadline, or cancellation while open).

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 are provided, so the description carries the full burden; it helpfully discloses cost (free), read-only intent, and the return shape (verified boolean plus capture time, coarse location, attestation reference). It omits auth requirements, rate limits, and what happens on a negative result, so it is only partially complete for an unannotated 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?

Two sentences, front-loaded with the cost signal and the core question, with zero filler. Every clause carries either trigger or return-value 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?

For a one-parameter tool with no output schema, the description usefully enumerates the return fields and the true/false semantics. It is nearly complete, lacking only failure/negative-case behavior and any auth or rate-limit context.

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 schema coverage at 100% and a single parameter, the schema already documents the hash input fully. The description restates that it is a sha256 of a capture, adding no format or encoding detail beyond the schema, so the baseline 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?

States a specific verb (check/verify) and a precise resource (whether a sha256 is a capture anchored by Vangrid on Base). An agent can distinguish this from siblings like vangrid_observation or vangrid_bounty_status without opening a schema because the anchoring/attestation concept is unique in the sibling set.

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 leading "Free." signals a cost consideration that implies when this cheap check is preferable, and the input (a sha256) makes the trigger obvious. However, it never explicitly says when to use this vs. alternatives or states prerequisites such as needing a previously anchored hash.

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