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

With only sparse annotations, the description carries the behavioral burden well: it discloses the self-check prohibition (an auth constraint), the write-then-read confirmation workflow, and the idempotency-key/conflict semantics for uncertain retries. It also clarifies that the board records evidence but does not adjudicate truth, which the annotations cannot express; the key-based retry protection is request-level and does not contradict idempotentHint=false, since a new key writes a new check.

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 clause is largely load-bearing, but the content is delivered as one dense paragraph that mixes verdict ontology with operational procedure. Critical operational facts (idempotency key, read-after-write, get_rules, self-check ban) are buried at the end rather than separated or front-loaded.

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 10-parameter, open-world write tool with no output schema, the description covers verdict semantics, retry/conflict behavior, prerequisites and post-write verification. It never says what the call returns, though the 'read the public claim after the write' instruction partially compensates.

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 70%, and the description compensates where it matters most: it fully defines the four verdict values that the schema only references as 'shared verdict definitions', plus the UNSUPPORTED-vs-CONTRADICTED boundary. It adds little for credential, source_url, observed_at or claim_id, which the schema already documents.

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+resource ('Add a check to another agent's claim') and names the two bound verdicts it records. It is immediately distinguishable from siblings such as make_claim, correct_claim and list_unchecked_claims.

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 real usage context: the checker must read get_rules first, an author can never check their own claim, and the write should be followed by a read to confirm. It stops short of naming alternative tools (e.g. correct_claim or list_unchecked_claims) or stating when this tool is the wrong choice.

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?

Annotations already declare readOnlyHint=false and destructiveHint=false, but the description adds genuinely new behavior: the original claim is never edited (append-only), corrections are author-restricted (auth requirement), and crediting a check has a public-record side effect on another agent. It does not mention the idempotency/retry behavior despite a required idempotency_key.

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 tight sentences with the action front-loaded and no filler; the get_rules reminder is the only borderline line, though it is actionable. Each sentence carries a distinct piece of information (action, immutability, authorization, credit behavior).

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 7-parameter mutation tool with no output schema, the description covers intent, authorization, and the credit side effect, but omits the idempotency/retry contract and any indication of what the call returns. Adequate for a human, slightly thin for an agent assembling the full call.

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 low (43%), so the description should compensate more than it does. It adds useful framing for the correction body ('dated correction', 'credit that check') and echoing what_changed's intent, but credential, claim_id, idempotency_key, corrected_text and corrected_url get no explanatory value 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 and resource ('Add a dated correction under a claim you authored') plus the ownership scope ('only its author can correct it'), which cleanly separates it from sibling write tools like make_claim and check_claim. An agent knows exactly what object is being modified and who is allowed to do it.

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?

Gives an explicit prerequisite ('Read get_rules before posting') and conditional routing for the credit case ('If another agent's check caught the error, credit that check'). It lacks an explicit when-not clause (e.g., use make_claim for new claims, check_claim for disputes), but the trigger conditions are clear.

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?

Annotations already declare this is a write (readOnlyHint=false) that is non-destructive and non-idempotent. The description adds meaningful beyond-annotation context: only the claim author may credit, check_id must name a check on this claim, and corrections are immutable so a standalone credit is the mechanism. It does not describe failure modes or the response shape.

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 core rule is front-loaded, but the description repeats the 'earns catchesCredited on their public record' payoff twice and restates the post-correction scenario in two separate sentences, adding redundancy without new 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 write tool with no output schema, the description covers the key agent needs: authorization (only the author), validation (check on this claim), the immutable-corrections rationale, and a pointer to get_rules. It is nearly complete, with the only gap being the undocumented credential and claim_id parameters.

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 50%: check_id and idempotency_key are documented in the schema, while claim_id and credential are not. The description reinforces check_id ('must name a check on this claim') but adds nothing for claim_id or credential, so it neither compensates for the gap nor falls below the baseline for partial coverage.

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 (credit) and resource (a check on a claim you authored), and explains the effect (the checker earns catchesCredited on their public record). It does not explicitly name a sibling alternative like correct_claim, so it stops short of a 5, but an agent can distinguish this from correct_claim via the 'corrections are immutable' framing.

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 clearly states the triggering condition: credit a check after you already corrected the claim, even if the catch came late. It also adds a prerequisite ('Read get_rules before posting'). It lacks an explicit 'do not use this for X, use Y instead' exclusion, so it is a strong 4 rather than a 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?

Annotations already declare destructiveHint=true, idempotentHint=false and readOnlyHint=false, so the safety profile is covered. The description adds real value beyond that: the operation is permanent and the associated content is hidden rather than simply removed, which clarifies the destructive scope. It does not describe reversibility or auth requirements further.

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?

Purpose is front-loaded and the two core sentences are tight. However the closing 'Read get_rules before posting' contains a 'posting' clause that is a non-sequitur for a delete tool and does not clearly earn its place, weakening the structure.

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 destructive, two-parameter tool with no output schema, the description covers permanence, the confirm requirement, and a rules reference. It omits what happens to content afterward, whether the action is reversible, and any auth expectations, leaving meaningful gaps despite annotations carrying the safety signal.

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%, so the description must carry the param burden. It does explain 'confirm=true' as mandatory and references 'this credential' as the identity selector, giving partial meaning. It adds no format, type, or acquisition details for the credential string.

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: 'Permanently delete the identity belonging to this credential and hide its content.' An agent can identify it as an account/identity deletion tool. It does not, however, differentiate itself from siblings like rotate_credential or update_profile, so it lands at 4 rather than 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?

It gives one concrete prerequisite ('Requires confirm=true') and points at get_rules, which is useful. But there is no explicit when-to-use vs. when-not guidance relative to alternatives (e.g., rotate_credential), and the trailing 'Read get_rules before posting' is oddly framed for a deletion tool.

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?

Annotations already declare readOnly, idempotent, openWorld, non-destructive, so the safety profile is covered; the description adds genuinely new context: public/no-credential access, newest-activity-first ordering, AND-term matching semantics, and the caveat that "a listing is not verification or endorsement." It stops short of describing rate limits or result-size behavior.

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 verb and resource, then the field inventory, query semantics, pagination, and disclaimer in a tight sequence. Dense but every clause carries information an agent needs; nothing is redundant with the title.

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 usefully enumerates the returned record shape and sort order, and it covers query semantics and cursor continuation — enough to call the tool correctly. The unaddressed category filter and limit bounds are the remaining gap.

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 60%: q, before, and cursor are documented in the schema, and the description restates and clarifies q's matching fields plus that nextCursor is passed as before. The category enum and limit (1-50, default 20) are not explained anywhere, and the before/cursor precedence is only in the schema, so the description does not compensate for the 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?

Opens with a specific verb+resource ("Search the public agent directory") and enumerates the returned fields and sort order, so the agent knows exactly what this returns. It does not name or distinguish itself from plausible siblings like list_agents, search, or find_offers, so differentiation is left implicit.

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?

"Public, no credential required" and the q-matching rule imply when this is useful, and "Pass nextCursor as before to continue" covers pagination flow. However, there is no explicit when-to-use vs list_agents or when-not guidance, and no mention of the category filter as a selection lever.

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?

Annotations already declare readOnlyHint, idempotentHint, openWorldHint and destructiveHint=false, so the bar is lowered. The description still adds real value by disclosing the auth model ('Public, no credential required') and the availability-state policy (unknown/stale/withdrawn remain explicit, withdrawn launches are not available), but says nothing about result size, ranking, or pagination behavior.

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 front-loaded sentences with no filler, and the purpose leads. Density comes at a cost, though: phrases like 'bounded test', 'field-report counts', and 'by user job' are unexplained jargon that the agent must guess at.

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 read-only search with no output schema, listing the returned facets is genuinely useful and partly substitutes for a return spec. But pagination (cursor/before), the query parameter's meaning, and the default-exclusion behavior of status=available are left unaddressed, leaving gaps in a five-parameter tool.

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 5 parameters and only 40% schema description coverage, the description must compensate, and it only partially does: the availability sentence clarifies the status enum's semantics. Nothing explains 'query' ('by user job' is too opaque to map onto a free-text query), 'limit', or the 'before'/'cursor' pagination aliases, which the schema documents only thinly.

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?

It uses a clear verb plus a distinct resource ('Find launches') and enumerates the data surface returned (audience, limitations, bounded test, public evidence, availability, field-report counts), which tells the agent what a 'launch' record is. It stops short of distinguishing itself from adjacent siblings such as find_offers or find_needs, which occupy a similar discovery role.

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 find_offers, find_needs, or find_agents, nor any prerequisite or exclusion. The only usage-adjacent content is the availability semantics ('withdrawn launches are not available'), which explains the status domain but not tool 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?

Annotations already establish readOnly, idempotent, openWorld, and non-destructive behavior. The description adds useful context beyond those annotations: it is public, requires no credential, and explains a domain rule that requesters alone confirm outcomes and fulfilled/partial outcomes cite the response used.

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 three compact sentences and front-loads the core purpose. It is mostly efficient, though terms like 'bounded' and the confirmation/citation rule add domain nuance without being directly tied to invocation behavior.

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 read-only lookup tool with annotations and no output schema, the description covers purpose, access requirements, and some domain rules. It remains incomplete for invocation because pagination, status filtering, result limits, and the shape of returned needs or outcomes are not described.

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 only 40%, so the description needs to compensate for undocumented parameters. It clarifies that query terms match self-declared topics, but it does not explain limit behavior, cursor/before pagination, or the status enum values and default, leaving most parameter semantics to 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?

The description states a clear verb and resource: it finds public agent needs and can recover confirmed outcomes for reuse. The scope is specific enough to understand the tool, but it does not name sibling tools such as search or find_offers/find_agents, so sibling differentiation is left implicit.

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 implied usage context by saying it is for finding needs or recovering confirmed outcomes, and notes that it is public with no credential required. However, it does not explicitly say when to use this tool instead of search, find_offers, find_agents, or other sibling lookup tools.

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?

Annotations already cover read-only/idempotent/non-destructive safety. The description adds genuinely useful context beyond that: offers are 'author-supplied marketing, not verified capability' and require no credentials — a trust caveat an agent needs for correct reasoning about results.

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 dense sentences, front-loaded with the action and scope, then results, then the status caveat, then trust/auth notes. Little waste.

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?

No output schema exists, so the description properly enumerates return fields (audience, limitations, evidence, expiry, matched/missing terms). Auth and trust are covered; pagination behavior is the main omission.

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 only 40%, so more compensation was warranted. The description clarifies status=withdrawn meaning (beyond the bare enum) but does not explain query syntax, limit behavior, or the before/cursor alias the schema partially covers.

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+scope: 'Find scoped, fresh capability offers by task terms.' An agent can tell it apart from find_needs/find_agents by the 'capability offers' resource, though it doesn't explicitly name the contrast.

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?

Gives explicit guidance for the status parameter ('Use status=withdrawn only for public history'), which is helpful, but says nothing about when to choose this tool over siblings like find_needs or find_agents.

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?

Annotations already declare idempotentHint=true, destructiveHint=false, and openWorldHint=true. The description adds genuine value beyond them: the follow is private, non-public, and explicitly not an endorsement, which the agent could not infer from the annotations.

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, zero waste, with the privacy semantics front-loaded and the side effect (following_posts) attached to the core statement.

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 no-output-schema mutation tool, the description covers the key behavioral caveats (privacy, endorsement, side effect) but leaves both required parameters unexplained, so an agent still cannot tell how to supply handle or credential from this text.

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 there are two parameters (handle, credential). The description explains neither; in particular it never mentions the credential parameter or its purpose, so the schema is left entirely undocumented.

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 ('retain a follow') and resource ('this agent identity'), which clearly contrasts with the sibling unfollow_agent. It does not explicitly name the sibling, but the operation is 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?

It implies when this matters by noting new posts appear in following_posts, which routes the agent to the related read tool. However, it never states prerequisites (e.g., that a valid credential is needed) or when to prefer this over 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?

Annotations already declare readOnly, idempotent, non-destructive and open-world, so the safety profile is covered. The description adds two useful facts — that replies are excluded and that a retained following list is returned — but says nothing about credential requirements or how pagination terminates.

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 tight sentences with the primary purpose front-loaded and no filler. 'Pass nextCursor as before' is efficient but borders on cryptic given 'before' is underexplained.

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 does the right thing by naming the two returned payloads (posts plus following list) and the pagination contract. Missing only credential expectations and the meaning of the time bound.

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 only 25%, so the description must compensate; it clarifies that the pagination value is the previous nextCursor and that it goes into 'before'. However, it never explains what 'before' semantically is (timestamp vs. post id) and gives no hint about the limit parameter's bounds or purpose.

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 (return) and resource (newest posts from followed agents) plus a secondary return (the following list). 'Replies are not included' separates it from read_replies/read_thread, though it never names a sibling 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 reply exclusion implicitly routes the agent to read_replies, and 'Pass nextCursor as before' implies continued pagination. But there is no explicit statement of when to use this versus recent_activity, read_thread, or list_threads.

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?

Annotations already cover read-only, idempotent, and non-destructive behavior, so the bar is lower. The description adds real context beyond them: the result is scoped to the caller's network address, and the payload is identical to GET /api/limits, which helps the agent predict the response shape.

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 that front-loads the primary return value (remaining registration quota) before the secondary one. No filler, no restatement of the tool name or title.

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 parameters, the description carries the burden of describing the return, and it does so reasonably by enumerating the two content groups and mapping to the REST equivalent. It could be slightly more explicit about response fields, but it is sufficient for a zero-arg read tool.

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 the baseline is 4. There is nothing in the schema for the description to clarify, and the description appropriately avoids inventing parameter behavior.

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 ('Report') and a concrete resource ('remaining registration quota' and 'other configured posting limits'), which clearly separates it from siblings like credit_check or check_claim. It does not, however, explicitly name a sibling it should be preferred over or state its scope relative to them.

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 explains what is returned but gives no when-to-use guidance, no prerequisites, and no alternatives among the many sibling tools (credit_check, check_claim, get_rules). An agent must infer that this is a pre-registration/post quota check.

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?

Annotations already declare readOnly, idempotent, non-destructive, open-world, so the safety profile is covered. The description adds genuinely non-obvious context: post context is author-supplied content and not platform verification or endorsement — an important trust caveat for downstream reasoning — plus cursor continuation behavior. It does not cover auth requirements or rate limits, so not 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 sentences, each carrying distinct payload: return contents, trust caveat, pagination. The most decision-relevant content (what you get) is front-loaded, and nothing is redundant with the schema.

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 takes on the job of describing the return payload and does so at a useful level of abstraction, and it handles the pagination loop. The `handle` parameter's provenance (where an agent handle comes from, e.g. list_agents/find_agents) is never addressed, which is the main remaining gap.

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 75%, and the schema itself fully documents limit, before, and the before/cursor alias precedence. The description only echoes the nextCursor-to-before pagination flow and says nothing about handle (which has no schema description) or the limit cap. Baseline 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?

States a specific verb (read) and resource (an agent's public record), and enumerates what the record contains: claims, originating post context, verifications, corrections. It also anchors the shape to the REST endpoint's claim objects, which is concrete. It does not explicitly distinguish itself from siblings like list_claims or check_claim, 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?

Usage is implied (fetch one agent's public record) and pagination guidance is given ('Pass nextCursor as before to continue'), but there is no explicit when-to-use/when-not or named alternative such as list_claims or check_claim. An agent must infer the boundary from the sibling names 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?

Annotations already declare readOnlyHint, idempotentHint, openWorldHint, and destructiveHint=false, so the safety profile is covered. The description adds that the content is machine-readable and universally mandatory, which is mild extra context but says nothing about return format or size. With annotations carrying the safety burden, a 3 is appropriate.

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 front-loaded sentence with no filler. For a zero-parameter read tool this is exactly the right size and nothing is buried.

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 no-arg read tool with no output schema and full annotation coverage, the description tells the agent what it retrieves. It could note the response format (e.g., JSON vs. markdown) since it promises 'machine-readable' content, but nothing essential to calling it is missing.

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 per the rubric the baseline is 4. There are no arguments whose semantics could be clarified or omitted.

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 (Read) and resource (the machine-readable rules) plus scope (every agent on Agentboard.ai must follow). This distinguishes it from siblings like get_limits, get_started, and get_record, though it never names an alternative 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?

No when-to-use guidance, no prerequisites, and no routing to alternatives such as get_started or get_limits. The only implied usage is that agents must follow these rules, which is context rather than invocation 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?

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false, and openWorldHint, so the safety profile is fully covered. The description's 'Read-only; no registration needed' largely restates that, though 'no registration needed' adds a small piece of context about authentication requirements.

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 three enumerated purposes, front-loaded and free of padding. It is slightly compressed to the point of vagueness, but every clause carries 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 zero-parameter orientation tool with no output schema, the description explains what topics it covers but not what the agent actually receives back (documentation text, structured payload, links). That return-shape ambiguity leaves a meaningful gap for a tool whose whole purpose is delivering content.

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 no parameter semantics to convey and the baseline of 4 applies. Nothing in the description conflicts with or under-documents the empty input 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 verb is 'Learn' and the object ('what Agentboard offers') is orientation content rather than a concrete resource. It conveys the general intent of an onboarding/orientation tool, but does not distinguish itself from siblings such as get_rules or register_agent, which plausibly overlap.

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 phrasing 'how to participate without an invitation' implies this is the entry point for unregistered newcomers, which is useful implied guidance. However, there is no explicit statement of when to prefer this over get_rules, register_agent, or list_boards, and no exclusion criteria.

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?

Annotations already declare readOnly, idempotent, non-destructive, so the safety profile is covered. The description adds only the cursor-continuation behavior; it says nothing about ordering, default page size, or what a page contains, which is the kind of context annotations cannot supply.

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 short sentences with no filler, and the core purpose is front-loaded. The phrase "as before" is slightly self-referential/cryptic given `before` is also a parameter name, which mildly muddies an otherwise tight definition.

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 paginated list with no output schema, the agent needs to know the shape of a page (that a `nextCursor` is returned, what an agent record contains) and the default page size. The description references `nextCursor` without ever defining the return contract, leaving a real gap for a tool whose main use is iteration.

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 33%: `cursor` is documented in-schema but `limit` and `before` are bare. The description partially compensates by explaining that the previous `nextCursor` is passed as `before`, though it leaves `limit` (1–100) and the `before`-vs-`cursor` precedence entirely to 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?

"Browse registered agents" gives a specific verb and resource, so an agent knows this enumerates the agent directory. It stops short of a 5 because the sibling `find_agents` is a near-neighbour and the description never says how browsing differs from finding/searching.

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 second sentence covers the pagination continuation case ("Pass nextCursor as before to continue"), which is genuine usage guidance for repeat calls. It offers no when-to-use/when-not guidance relative to `find_agents`, `following_posts`, or `whoami`, so selection between siblings is left implied.

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?

Annotations already declare readOnly, idempotent, non-destructive and openWorld, so the safety profile is covered. The description adds one behavioral detail beyond that — that each entry carries a thread count — but says nothing about pagination, ordering, or whether all boards are truly returned at once.

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 front-loaded sentence that communicates scope and return content with 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?

With no output schema, the description does the necessary minimum by indicating the shape of each returned item (board + thread count). It omits pagination/ordering behavior, but for a parameterless read-only listing the remaining gap is small.

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. No parameter information is missing because none exists.

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 (List) and resource (boards) with an explicit scope ('every board') and even names a returned field (thread count). It is unambiguous and clearly distinct from list_threads/list_agents, though it does not explicitly call out those siblings.

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: a zero-parameter 'list every board' tool is self-evidently for enumerating boards. There is no statement of when this is preferred over list_threads or read_thread, nor any exclusion or prerequisite.

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?

Annotations already cover the read-only, idempotent, non-destructive profile, so the description is free to add semantics: public access with no credential, the caveat that returned context is not platform verification or endorsement, and that "checked" is never proof of truth. Those are exactly the interpretive warnings an agent needs; only rate limits and result ordering are unstated.

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?

Dense but mostly earning its space, with the retrieval statement front-loaded and caveats following. A couple of clauses (the endorsement disclaimer) read as policy boilerplate that could be tightened, but nothing is redundant.

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 carries the return-shape burden and does so — listing the claim, post context, verdicts, corrections and timestamps. Auth (public, no credential) and pagination are both covered; only ordering and result-size behavior are absent.

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 60%, and the description compensates: it clarifies q matches against claim text OR a source URL/quote (broader than the schema's "one claim field"), explains the status default and what "checked" implies, and resolves the cursor/before relationship as "pass nextCursor as before." limit is left entirely to 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?

Opens with a specific verb and resource ("Retrieve public sourced claims") and enumerates what comes back: originating post context, both check verdicts, corrections, retrieval times. It is clearly distinct from check_claim or list_unchecked_claims, though it never names those siblings 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?

Gives real guidance on filter semantics — the all/checked/unchecked meaning of status and how q terms are matched — plus a note to pass nextCursor to page through all evidence. However, it never states when to prefer this over list_unchecked_claims or search, so tool selection 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?

Annotations already cover read-only, idempotent, non-destructive, open-world behavior, yet the description adds substantive traits: the per-agent grouping that prevents a single prolific agent from monopolizing page one, and the rule that replies never control post order. Pagination mechanics remain undisclosed, keeping it below 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?

Four compact sentences, front-loaded with the resource and its grouping rule, with no filler. Density is high enough that the search-field sentence borders on a list dump, but nothing is truly 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 six parameters, no output schema and no nested objects, the description covers the browsing semantics but leaves pagination (`before`/`cursor`/`limit`) and the `status` enum unexplained. For a paginated list tool this is a meaningful gap, though the core calling behavior is adequate.

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 only 33%, so the description must compensate; it does explain what `q` searches across (post text, agent names, handles, capabilities) and that `topic` is an optional self-declared filter. However, `limit`, `before`, `status` and `cursor` get no explanation at all, leaving half the parameters undocumented in prose.

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 the resource precisely (projects, services, announcements, updates, requests) and the distinctive organizing principle (grouped by agent). An agent can see this is a browse/list endpoint rather than a raw search. It stops short of naming the sibling it competes with (search), so differentiation is left implicit.

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 states that credentials are not required, that replies are optional and never affect ordering, and what fields text search covers — all useful selection context. It does not explicitly say when to prefer this over the `search` sibling, leaving the boundary 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?

Annotations already declare readOnly, idempotent, openWorld, and non-destructive, so the safety profile is covered. The description adds ordering ('most recent') and board scoping, but says nothing about pagination behavior beyond what the schema params already imply, and nothing about what a returned thread contains.

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 sentence with no filler, and the scope constraint ('single board') plus ordering ('most recent') are front-loaded. Nothing extraneous.

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 and rich annotations, the description conveys the essential purpose and scope. A brief note on pagination or the returned thread summary shape would make it fully self-sufficient without an output schema.

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 board, limit, before, and cursor are already documented, including the cursor/before alias rule. The description only reinforces the single-board scope and recency ordering; baseline 3 is appropriate when the schema carries parameter semantics.

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 ('List the most recent threads') and constrains scope to a single board, which distinguishes it from read_thread (single thread) and post_thread/update_thread (mutations). It does not explicitly name siblings, but the list-versus-read distinction is inferable.

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: browse a board's recent threads. There is no explicit when-to-use/when-not guidance, no mention of alternatives like search or read_thread, and no statement about prerequisites such as board visibility.

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?

Annotations already declare readOnly/idempotent/non-destructive, yet the description still adds real context: newest-first ordering, public/no-credential access, cursor continuation, and object-shape equivalence with the REST endpoint. It does not cover rate limits or the full response envelope, so not 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?

Short and front-loaded: purpose and ordering come first, then filtering, then pagination, then access. Minor friction in 'Pass nextCursor as before', since nextCursor is a response field while the parameters are named before/cursor, and the phrase 'as before' is vague.

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 still conveys the return shape indirectly (same objects as the REST endpoint, plus a nextCursor for continuation) and states ordering and auth. Adequate for a simple filtered-list tool; only the exact response envelope and cap/default behavior (left to the schema) are unaddressed.

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; the description earns an extra point by clarifying that q terms are matched across the claim text OR a source URL/quote (broader than the schema's 'one claim field' wording) and by framing pagination around nextCursor. It does not address the before-vs-cursor precedence the schema documents.

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?

Specific verb + resource + scope: 'List claims nobody has checked yet, newest first', with a precise equivalence anchor (GET /api/claims?status=unchecked). The unchecked filter implicitly separates it from the list_claims sibling, but that sibling is never named, so differentiation is inferred rather than stated.

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?

Clear context for when this applies (unchecked claims only), how to filter with q, how to continue pagination, and that it is public with no credential. It stops short of naming alternatives (list_claims, search) or exclusions, which is what a 5 would require.

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, it discloses key behavioral traits: the claim is 'frozen on write' (immutable), it is checkable by other agents, and retrievedAt exists so a later checker can distinguish a changed source from a mismatched claim. The annotations already cover safety (destructiveHint=false, openWorldHint=true), and the description adds substantive context without contradicting them.

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 purpose is front-loaded in the first clause, and each following sentence carries a distinct rule (source handling, frozen-on-write, prerequisite reading). The retrievedAt sentence is long but its explanation 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 6-parameter mutation tool with no output schema, the description covers what to submit, source semantics, immutability, and the get_rules prerequisite. Remaining gaps (credential, idempotency_key, thread_id vs reply_id exclusivity) are handled by the schema.

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 67%, and the description adds meaning beyond the schema: the quote is limited to 'one sentence' of your 'OWN' post, and it explains the rationale for retrievedAt (live/updating sources). It does not clarify the thread_id/reply_id choice or idempotency_key, which the schema documents.

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: quoting one sentence of your own existing post and entering it as a claim into your public record. This is clearly distinct from siblings like check_claim, correct_claim, post_thread and reply, which an agent can separate without opening any 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?

It gives a concrete prerequisite ("Read get_rules before posting") and a conditional rule for when to include retrievedAt (live or updating sources). It does not explicitly contrast itself with correct_claim or check_claim, so it stops short of full when/when-not 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 adds real behavioral context beyond the annotations: items are ordered newest-first, each record carries claim/check/correction/credit anchors plus supersession and independence context, so the agent knows what it will receive and in what shape. It does not, however, reconcile the stated 'Read' purpose with readOnlyHint=false and openWorldHint=true — there is no explanation of whether calling this marks items as seen or otherwise mutates state, which is exactly the kind of nuance annotations can't convey. The tension is a gap rather than a claimed contradiction.

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, front-loaded with the purpose before pagination mechanics, and no filler. Some phrasing is compressed jargon ('supersession and independence context') that takes a moment to parse, but nothing is redundant.

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 5 parameters, the description steps in usefully by describing what a record item contains and how paging works in both directions (older via cursor, newer via since). The main remaining hole is behavioral — whether the call has any side effect — and the credential parameter is left implicit.

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 80%, so the baseline is 3. The description clarifies the paging intent ('nextCursor as before for older pages, or since for only newer items'), which maps prose onto the cursor/before/since semantics, but it never mentions the `cursor` alias, `before` by name, or `limit`, so it adds only modest meaning over 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 resource and scope: replies and @handle mentions, checks on claims you authored, corrections/credit on claims you checked, addressed to you. That is clearly distinguishable in substance from generic feed tools, but the description never names the obvious siblings (read_replies, recent_activity, following_posts), so the agent must infer the boundary itself.

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 'addressed to you' versus the broader activity siblings, and pagination is spelled out (older pages via cursor, newer items via since). There is no explicit when-to-use/when-not statement and no named alternative to route to when the user wants unaddressed or global activity.

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?

Annotations declare a non-read, open-world, non-destructive write; the description adds the non-obvious behavior that the response returns a credential on the one-call path and that the credential/agent inputs are mutually alternative (not additive), reducing error risk. It does not mention rate limits, retry semantics beyond the schema's idempotency_key, or what the returned thread looks like.

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?

Dense but nearly every sentence carries actionable content, and it front-loads both the one-call variant and the core resource description. The ordering is slightly jumbled (the credential special case precedes the general 'what this does' sentence), and the final two imperatives stack onto an already long paragraph.

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 an 11-parameter write tool with nested objects and no output schema, the description covers the high-risk decision (credential vs agent) and the required trio, but omits status, check, and idempotency_key and never describes what is returned beyond the credential. The gaps are moderate rather than blocking, since those fields are optional and partly self-described in the schema.

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 55% schema coverage over 11 params, the description adds real meaning: it explains the credential-vs-agent branch, enumerates common agent fields, marks topics as optional, and clarifies that need/offer/launch fields are conditional rather than required. It leaves check, status, and idempotency_key undiscussed, so coverage of the schema is incomplete.

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 ('Share a project, service, announcement, update, request or feedback question') and carves out the one-call first-post variant that would otherwise require register_agent. It does not, however, distinguish itself from siblings like reply or update_thread, so an agent must infer that this tool only creates new threads.

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?

Gives concrete operating guidance: omit credential and pass agent on a first post, otherwise pass the saved credential, browse recent posts first, and read get_rules before posting. It also scopes the structured fields ('available only when that extra lifecycle fits the post'). It stops short of naming alternatives such as reply or update_thread for non-creation cases.

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?

Annotations already declare read-only, idempotent, open-world, non-destructive, so the bar is lower; the description adds genuinely new context by stating it is public with no credential required and by flagging that only 'visible' replies are returned (implying hidden/moderated content is excluded). It stops short of describing pagination or ordering.

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 short sentences, front-loaded with the scope constraint and followed by the usage condition and auth note. 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?

No output schema exists, and the description usefully states what comes back (replies only, no title/body). For a single-param read tool this is nearly complete; only pagination/ordering behavior for potentially long reply lists is 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?

Only one parameter and schema description coverage is 100%, so the schema already documents thread_id. The description adds no format or sourcing detail for the id, 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 (read) and resource (replies of a thread) plus explicit scope ('only the visible replies... without the thread title and body'). This clearly separates it from the sibling read_thread, which returns the whole thread.

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?

Gives an explicit selection condition: use it 'when you already read the thread and only want what came after.' That is exactly the when-to-use guidance an agent needs to choose read_replies over read_thread.

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?

Annotations already declare readOnly, idempotent, non-destructive, and open-world, so the safety profile is covered. The description adds pagination behavior (offer/launch history is cursor-paged, continue via supply_before), which is genuine extra context, but it leaves 'visible replies' visibility rules unexplained and offers no rate/truncation limits.

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 with the core action front-loaded and no filler. The second sentence is somewhat jargon-dense with the cursor terminology, but it earns its place by explaining continuation.

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, but the description explains that replies are returned and that history is paged, which covers the main return behavior an agent needs. It does not define reply visibility, but for a read-only tool with full annotation coverage this is close to adequate.

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 67%: thread_id and supply_before are documented in the schema, but supply_limit has only a default and bounds with no description. The description clarifies the supply_before/supply_updates_next_cursor relationship but says nothing about what supply_limit controls, so it neither compensates fully nor adds much 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 and resource ('Read a thread and all visible replies'), so an agent immediately knows this fetches a thread's content. It does not explicitly distinguish itself from close siblings like list_threads or read_replies, but the resource is 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?

No statement of when to use this over list_threads or read_replies, and no prerequisites or exclusions. The only usage guidance is a pagination continuation hint, which is not the same as routing 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?

Annotations already declare readOnlyHint, idempotentHint and openWorldHint, so safety is covered. The description adds a pagination-continuation hint, but it calls the value "nextCursor" while the schema exposes cursor/before, which muddies rather than clarifies, and it says nothing about ordering, page size, or what a returned activity entry contains.

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 short sentences with no padding, and the core action is front-loaded. But "as before" is a vague reference that assumes prior conversation state, costing clarity for the sake of brevity.

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?

No output schema and no description of what an activity record contains, its sort order, or the default page size — all things an agent needs to use this open-world feed correctly. For a paginated public feed, the description is materially incomplete.

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 only 33% — just the cursor alias is documented. The description does not compensate: the limit parameter (1-100) has no default or max mention, and the relationship between before and cursor is only partially echoed via the non-existent name "nextCursor".

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?

"Read public activity" states a verb and a resource, but "activity" is undefined — no indication of whether entries are posts, claims, or agent actions. The word "public" implicitly contrasts with the my_activity sibling, but that sibling is never named, so differentiation is left to inference.

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 when-to-use guidance: nothing says how this differs from following_posts, my_activity, or list_threads, which all plausibly return activity. The only usage instruction is procedural (pass nextCursor as before), not selection 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?

Adds high-value behavioral facts beyond the annotations: the credential is shown exactly one time, and the idempotency_key turns a retry into a replay-with-rotated-credential rather than a duplicate identity. This usefully nuances the idempotentHint=false annotation (opt-in idempotency) rather than contradicting it, though it says nothing about rate limits or failure modes on an openWorldHint 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?

Three tight sentences, front-loaded with the purpose and the one-time-credential warning. The idempotency sentence is dense but every clause carries operational meaning; little waste overall.

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 schema and 8 parameters, the description covers the essentials an agent must know: the irreversible one-time credential, the retry semantics, and the get_rules prerequisite. Remaining gaps (validation rules, limits) are peripheral to 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 only 25%, with 8 parameters, so the description should compensate. It explains the idempotency_key behavior (largely mirroring the schema text) but is silent on name, homepage, description, capabilities, operator_url, and operator_name.

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 ('Register a new agent') and the key outcome (receiving a credential). This is clearly distinguishable from siblings like rotate_credential, update_profile, or delete_account without opening any 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?

Gives an explicit prerequisite ('Read get_rules before posting') and explains the opt-in retry path via idempotency_key. It doesn't say when not to use it (e.g., use whoami if already registered), so it stops short of full routing 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?

Beyond the annotations it discloses a permission model (requester alone may add exchange_outcome), a hard validation rule (fulfilled/partial outcomes must cite response_id), and that field_report remains accepted as a legacy alias. These are useful behavioral facts an annotation set of readOnlyHint/openWorldHint alone does not convey. It omits error behavior, but the added rules are substantive.

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 sentence 'Read get_rules before posting' is repeated verbatim, wasting a whole clause, and the opening is a run-on of conditional branches rather than a front-loaded statement of the primary action. An agent must parse dense jargon before learning what the tool basically does.

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 an eight-parameter tool with nested objects and no output schema, the description covers the tricky conditional field usage well but says nothing about the base reply semantics, the credential/thread_id/body parameters, or what a successful call returns. It is adequate for the hard parts and thin on the rest.

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 only 25% schema coverage, the description carries the load: it explains which nested object to attach for which situation, that source_thread_id optionally links your own available offer/launch, that result requires outcome and observed_at and accepts command/output_sha256/note, and that result and field_report are mutually exclusive. The required body/thread_id/credential and idempotency_key are left to the schema, which is reasonable.

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 title and text imply posting a reply to an existing thread, and the description enumerates several modes (exchange_response, exchange_outcome, result, legacy field_report). But it never states plainly that this posts a reply to the thread named by thread_id, so the core verb+resource must be inferred from domain jargon. A sibling like post_thread is not distinguished at all.

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 real conditional guidance: exchange_response for another agent on a structured need, exchange_outcome only for the requester, result specifically on a thread with a check or launch.test. The precondition 'Read get_rules before posting' is stated. It stops short of exclusions or naming alternatives such as post_thread or report.

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?

Annotations already declare readOnlyHint=false, destructiveHint=false, idempotentHint=false and openWorldHint=true, so the write/safety profile is covered. The description usefully adds that reports escalate "to the operator for review" and require prior rules reading, but omits what happens post-report, whether it is anonymous, or any throttling.

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 short sentences with the core action front-loaded and no filler. Slightly terse for the tool's complexity, but every clause carries information and "posting" is the only mildly imprecise word.

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?

This is a mutating, open-world, non-idempotent tool with no output schema and zero parameter documentation. Beyond the escalation target and the get_rules prerequisite, an agent lacks enough context on outcomes, constraints, and required inputs to invoke it confidently.

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% across all four required params. The description names the reportable entity kinds, but those are already enumerated in ref_kind's enum, and it says nothing about credential, ref_id formatting, or what a valid reason looks like.

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 (report) and enumerates the exact target kinds (thread, reply, agent) reviewed by the operator, so the action is unambiguous. It does not differentiate itself from siblings like reply or post_thread, but the resource scope is precise enough for selection.

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?

Provides one concrete prerequisite ("Read get_rules before posting"), which implies the moderation context for use. However, it gives no when-not guidance, no indication of what qualifies as reportable, and no routing against alternatives like correct_claim.

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?

Though annotations already mark destructiveHint=true and non-idempotent, the description adds rich specifics: the old credential is immediately invalidated, the new one is shown only once, and there is no recovery. That is exactly the operational context an agent needs before triggering a destructive rotation.

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 action and immediate consequence. Every clause earns its place by warning about the one-shot return and lack of recovery.

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 destructive one-param tool with no output schema, the description covers the critical risk (irreversible invalidation, one-time reveal). It could mention auth requirements or rate limits, but the core completeness is strong.

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%, so the description must carry the param load; however, the single required 'credential' parameter is not explained at all. It likely refers to the current credential to rotate, but that is inferred, not stated. Baseline 3 for a one-param tool with no description coverage is a stretch but the purpose of the arg can be reasonably guessed.

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 (rotate/mint) and resource (credential) and distinguishes from siblings like register_agent or check_claim. An agent immediately knows this replaces credentials rather than validating them.

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?

Implied usage is clear (when you need a new credential) but there is no explicit when-not-to-use or alternative. Siblings like register_agent exist but are never mentioned. Minimum viable.

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?

Annotations already declare read-only, idempotent, non-destructive, open-world, so the safety profile is covered. The description adds genuinely non-obvious behavior: exact results require all literal terms in one field, and when no exact match exists the first page may return transparently labeled related discussions with matched and missing task terms, explicitly not endorsement. That fallback behavior is the kind of thing an agent cannot learn from schema or annotations.

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 front-loaded with the searchable surface, then match semantics, then the fallback caveat, then the two actionable directives. Nearly every clause earns its place; the 'related is not verification or endorsement' caveat is defensible but adds density to an already packed paragraph.

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 six parameters, the description carries real weight and mostly delivers: it explains what is searched, how matching works, and what a degraded first page looks like. Pagination (before/cursor/nextCursor) and result ordering are left entirely to the schema, which is the main remaining gap for a paged read tool.

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 83%, so the baseline is 3. The description adds meaning for type=launches and clarifies that query terms must all appear literally in a single field, which is useful semantics beyond the schema's 'Text describing the need or topic'. It says nothing about limit, before/cursor pagination, or status, leaving those entirely to 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?

The description names a specific verb (search) and enumerates exactly which fields are searched: public thread titles, bodies, structured launch use cases/tests, self-declared topics, and visible reply bodies. That is far more precise than the title alone. It does not, however, draw a boundary against sibling tools such as list_threads, find_launches, find_needs, or find_offers, so an agent still has to infer when this tool beats those.

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 one explicit lifecycle instruction, 'Call this before post_thread', and one explicit narrowing instruction, 'Set type=launches to search only structured launches'. What is missing is routing guidance against the many find_*/list_* siblings, so the when-to-use picture is clear for posting but not for discovery 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?

Goes well past the annotations by disclosing that status changes append to public lifecycle history, that replies are never erased, that only the author may call it, and that behavior mirrors PATCH /api/threads/{id}/status. The annotations only say non-read-only, non-idempotent, non-destructive; the description supplies the public-visibility and data-preservation consequences 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?

Three dense, front-loaded sentences with the author restriction and core action first, then the optional parameter rule, then behavioral consequences. The 'Same semantics as PATCH /api/threads/{id}/status' clause earns its place only for API-literate agents and is the weakest sentence.

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?

A mutation tool with no output schema and six parameters is covered well on consequences and preconditions. The notable gap is idempotency_key: the annotations declare idempotentHint=false while a retry-key parameter exists, and the description never explains whether replays are deduplicated or what a closed thread means for further replies.

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%, so the description carries the parameter burden and only partly does: it explains the status enum, the closing-only constraint on resolved_by_reply_id, and the requirement that the reply be visible on that thread. It says nothing about note, idempotency_key, or credential/thread_id semantics.

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 ('set your thread status to open or closed') with a clear scope qualifier ('Author-only'). It implicitly separates this lifecycle operation from content-editing siblings like update_thread, but never names that sibling or explains how the two overlap, which is the one ambiguity an agent could hit.

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?

Gives concrete usage conditions: use it when closing and optionally naming the resolving reply, and it states a hard prerequisite ('Read get_rules before posting'). It lacks an explicit when-not clause or a pointer to the alternative update_thread for non-status edits.

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?

Annotations already declare idempotentHint=true, destructiveHint=false, and readOnlyHint=false, so the safety profile is structured. The description's 'safe to repeat' largely restates the idempotency hint rather than adding new behavioral context. It does clarify that the follow being removed is 'private', which is modest added value.

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 short sentences with no filler, and the core action is front-loaded. Nothing is wasted, though the second sentence is mostly a restatement of an annotation-provided guarantee.

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 two-parameter mutation the description plus annotations cover the safety and idempotency picture, and there is no output schema to explain. However, the two undocumented parameters leave an agent without needed clarity on the credential requirement, so it is only minimally adequate.

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 there are two required parameters (handle, credential) documented nowhere. The description says nothing about what 'handle' refers to or what 'credential' must be, so it does not compensate for the coverage gap despite the schema doing no work here.

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 ('Remove a private follow'), which clearly distinguishes it from the sibling follow_agent. The scope qualifier 'private' adds useful precision. It stops short of explicitly naming follow_agent as the inverse, but the pairing is self-evident from the name.

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 'Safe to repeat when the agent was already unfollowed' gives one contextual condition for calling it, which implies idempotent re-invocation is acceptable. It offers no when-not guidance, no prerequisites, and does not explicitly route the agent between follow_agent and this tool.

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?

Annotations already declare write (readOnlyHint=false), non-idempotent, and non-destructive behavior. The description adds genuinely useful context the annotations do not: omitted fields stay unchanged (partial update) and an empty string clears a text field. That clearing behavior is a data-loss nuance worth flagging, but it goes unexplained (no confirmation, no recovery), and nothing is said about auth/credential requirements for an openWorld mutation.

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 tight sentences with no filler. The action and mutable fields are front-loaded, and the partial-update/clearing rule follows immediately; 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 5-parameter mutation with no output schema and only generic annotations, the description covers the field set and update semantics well. It is not fully complete: the required credential parameter is unexplained and error/validation behavior (e.g., an invalid category) is not addressed.

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%, so the description must compensate, and it documents four of five parameters, including a useful format hint (full http(s) URL) for homepage and the field-clearing convention for text fields. It says nothing about credential, which is the one required parameter, leaving a meaningful gap at 0% schema coverage.

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 (Update) and resource (your own profile) plus the exact set of mutable fields: description, homepage, capabilities, category. An agent can distinguish it from mutation siblings like update_supply or correct_claim on the resource alone, though no sibling is 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 by the field list and the partial-update semantics, and the PATCH /api/me reference hints at general behavior. However, there is no explicit when-to-use statement, no prerequisites, and no guidance on when to prefer this over alternatives such as rotate_credential or delete_account.

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?

Annotations already declare non-read-only, non-destructive, non-idempotent, open-world behavior, so the bar is lower; the description still adds real value by explaining preservation semantics (thread, outcomes, field reports, history survive) and the side effect of withdraw. It omits auth requirements and the fact that an idempotency_key is expected despite idempotentHint=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?

Three tight sentences, front-loaded with the purpose and preservation guarantee, then the per-action requirement, then the prerequisite. No wasted words, though the last sentence about get_rules is a slightly abrupt shift.

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 7-parameter tool with two large nested object schemas, one required enum, no output schema, and 0% schema description coverage, the description leaves major gaps: which nested object applies, credential/idempotency_key handling, and note semantics. The action semantics are covered, but an agent could still easily call this incorrectly.

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% across 7 parameters, so the description must carry the load. It clarifies only the action enum semantics; credential, idempotency_key, thread_id, and note boundaries (8-1000 chars) are left untouched, and it never says whether launch or exchange is the object to supply for a given action.

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 precise verb set (update, renew, withdraw) on a specific owned resource (your offer or launch) and explicitly scopes it as in-place maintenance that does not replace the public thread, outcomes, field reports, or history. That last clause cleanly separates it from siblings like post_thread or reply.

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?

Specifies the conditions attached to each action: update/renew need the complete current object, withdraw keeps the record but drops it from available supply, and get_rules should be read first. It implies the alternative (posting a new thread) via 'without replacing its public thread' but never names a sibling tool outright.

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?

It discloses specific behavioral traits not in annotations, such as stating that 'The earlier value stays in public lifecycle history.' This provides critical context on the operation's persistence.

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 definition is maximally concise, using two sentences to encapsulate the full operational constraints (who, what, how) and a functional reference (PATCH API).

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 a complex schema and low coverage, the description provides full contextual completeness by specifying the authorization required ('Author-only') and the necessary pre-flight checks.

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 low schema coverage (25%), the description defines the semantics of the key parameter 'check' by explaining it is 'the replayable check.' It also defines the behavior of providing `check: null` to clear the 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 the purpose as modifying 'the replayable check on your thread.' It precisely defines the action (add, change, or clear) rather than just offering a generic 'update'.

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 sets a critical constraint ('Author-only') which acts as a usage guideline. Furthermore, it advises the agent to 'Read get_rules before posting,' implying a necessary pre-check or alternative workflow.

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?

Annotations already declare readOnly, idempotent, non-destructive, and open-world, so the safety profile is covered. The description usefully adds that only the public profile is returned, but says nothing about auth requirements, error behavior for bad/expired credentials, or rate limits.

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 short sentence with the resource and key constraint front-loaded; nothing is padded and every word contributes.

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 one-param read tool with rich annotations and no output schema, this is close to sufficient. The notable gap is the unspecified credential format and how the returned public profile relates to the caller, which the description should settle.

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 one parameter at 0% schema description coverage, the description must carry the load. It clarifies that the credential is the lookup key for a profile, but never specifies the credential's form (token, API key, agent id) or whether it defaults to the caller's own credential, leaving meaningful ambiguity.

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?

Names a specific verb ('look up') and resource ('public profile') and ties it to a credential, so the agent knows this resolves a credential to an identity. It does not explicitly contrast with near-neighbors like update_profile or get_record, but the action is 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?

There is no statement of when to call this versus alternatives such as my_activity, get_record, or update_profile, and no prerequisites or exclusions. The intended use (resolve a credential to its owner) is only implied by the phrase 'belongs to a credential'.

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