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 usefully discloses the key behavioral trait that claiming acquires an execution lease and guarantees exclusive processing, but says nothing about idempotency, what happens if the job is already claimed, whether the lease expires, or the sibling operate_heartbeat's role in renewing it.

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?

One sentence, front-loaded with the core action and followed by the exclusivity rationale. 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?

For a mutation tool with no annotations and no output schema, the description covers the exclusivity contract but omits failure modes (already-claimed job) and lease lifecycle details. It is adequate to attempt the call but not complete enough to predict behavior under contention.

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 single jobId parameter is fully documented there ('UUID of the queued job order to accept'). The description adds no format, constraint, or sourcing detail beyond the schema, so the baseline 3 for a well-covered schema 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+resource (claim a job) plus the mechanism (execution lease), and the exclusivity clause clearly separates it from siblings like operate_check_queue, operate_list_gigs and operate_submit_fulfillment. An agent can tell what this does 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?

Usage is only implied: 'queued job' and 'no other agent instance processes it' suggest calling this after checking the queue and before submitting fulfillment, but no explicit when-to-use or when-not-to-use guidance or alternative tool is named. The sequencing logic 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?

No annotations exist, so the description carries the full behavioral burden. It does add real domain context (jobs are escrow-funded and buyer-purchased), and 'check' strongly implies a read-only poll, but it never says whether reading drains/claims the queue, whether auth is required, or how often to poll versus calling operate_heartbeat.

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?

One short, front-loaded sentence with no padding. It is slightly loose in its 'jobs/orders' duality, but nothing 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?

For a zero-parameter, no-annotation, no-output-schema tool the description is minimal but workable. It omits the relationship to accept_job/submit_fulfillment and what checking returns or does to the queue, so it is adequate rather than 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?

The tool takes zero parameters, so there is nothing for the description to disambiguate; baseline 4 applies. Schema coverage is 100% trivially by virtue of an empty 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?

The description gives a specific verb (check) and a specific resource (incoming queue of escrow-funded jobs/orders), plus the qualifier that buyers purchased them from your agent. That is clearly distinguishable from create_gig or list_gigs, though it never names a sibling to route against.

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 only implied by the phrase 'check for new' - it suggests a polling step before accept_job, but no when-to-use condition, prerequisites, or alternative tool is stated. An agent can infer the moment to call it but gets no explicit 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?

No annotations are provided, so the description carries the full disclosure burden, yet it only says the gig becomes publishable so 'buyers can hire your agent'. It omits auth requirements, whether publishing is immediate or requires review, idempotency/duplicate handling, and pricing constraints that the mutation implies.

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?

It is a single front-loaded sentence with zero wasted words, clearly stating verb, resource, and effect. It is arguably too terse for an 8-parameter mutation tool, which caps it below a 5.

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 create/publish mutation with 8 parameters (3 required), nested schema objects, no annotations, and no output schema, the description should cover auth needs, publish semantics, and failure modes. It covers none of these, leaving the agent under-informed for a write operation.

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 schema already documents all 8 parameters including the nested input/output schemas and defaults. The description adds no parameter-level meaning beyond that, 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 names a specific verb pair ('Create and publish') and resource ('capability/gig') on a named marketplace, so the purpose is unambiguous. It does not explicitly contrast itself with the sibling tools (list, queue, accept, submit, heartbeat), so it stops short of a 5.

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?

There is no guidance on when to use this tool versus the siblings, nor any prerequisites (e.g. whether an agent must already be registered, whether an existing gig should be edited instead). Usage is only inferable from the purpose statement.

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 does disclose the observable effect (maintaining Fleet Ready status on Operate.Center), which is useful, but omits auth needs, the interval at which the heartbeat must be sent, and what happens if it lapses.

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 with the action and its consequence front-loaded and zero filler. Nothing redundant or padded.

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-param, no-output tool the description is nearly sufficient, but heartbeat semantics hinge on timing and failure behavior, neither of which is covered. An agent knows what the call does but not when or how often to make it.

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 takes zero parameters, so there is nothing for the description to disambiguate and the baseline of 4 applies. No parameter claims are made that could mislead.

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 ("Send a health heartbeat") plus the effect on the agent's status, which is a concrete outcome rather than a restatement of the name. It is clearly distinct from the job/gig-oriented siblings, though it never names them 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?

The phrase "to keep your agent's Fleet Ready status online" implies periodic use and the reason for calling it, which is enough to infer intent. However, it gives no frequency or cadence expectation and no when-not guidance, which for a heartbeat tool is a real gap.

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 supplied, so the description carries the full behavioral burden, yet it only implies read-only via the verb 'Browse'. It says nothing about pagination, result limits, authentication requirements, or whether the call has side effects, all of which an agent needs before invoking a marketplace listing 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?

It is a single front-loaded sentence with no filler, which is efficient. The terseness is borderline under-specification rather than verbosity, but nothing in the sentence 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 and no annotations, the description should explain what a caller gets back, but 'gigs and operators' is never clarified — it is unclear whether operators are returned as a separate collection, embedded in gigs, or not returned at all. For a browse tool this leaves the agent guessing about the response shape.

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% — the single optional 'category' parameter is already documented as an optional category filter — so the baseline is 3. The description adds no extra meaning about accepted category values, matching behavior, or how filtering interacts with the 'operators' portion of the results.

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 pairs a specific verb ('Browse') with a resource ('published gigs') and a named surface ('Operate.Center marketplace'), so an agent knows this is a read-oriented listing tool rather than a mutation. It does not, however, differentiate itself from the sibling 'operate_check_queue', which plausibly also surfaces pending work, and the trailing 'and operators' makes the returned resource slightly ambiguous.

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?

There is no statement of when to use this tool versus alternatives such as operate_check_queue, nor any prerequisites, filters guidance, or exclusions. The agent is left to infer that this is the marketplace-browsing entry point purely from the word 'Browse'.

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 behavioral burden. It usefully discloses the downstream effects — order moves to buyer review and escrow payout is released — which is important side-effect context. However, it omits reversibility, idempotency, permission/auth requirements, and what happens on a rejected or partial submission.

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 tight sentence with the action and consequence front-loaded. No filler, every clause 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 mutation tool with no annotations and no output schema, the description covers the state transition and escrow consequence but leaves gaps around failure modes, re-submission behavior, and preconditions. Adequate but not complete for the risk profile of releasing escrow funds.

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 jobId, summary, and result_data are already documented in the schema. The description implies jobId and the result payload but adds no format, size, or validation detail beyond the schema, 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?

States a specific verb (Submit), a specific resource (the completed deliverable payload for a job), and the resulting state transition. It is clearly distinct from the sibling tools (create_gig, list_gigs, check_queue, accept_job, heartbeat), though it does not name them 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?

The description implies the correct moment to call it (once the deliverable is completed), but gives no explicit when/when-not guidance, no prerequisites (e.g. must the job be accepted first, must a heartbeat be active), and no mention of alternatives or ordering relative to siblings.

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