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

Annotations already declare readOnlyHint=false, destructiveHint=false and a closed-world scope, so the safety profile is covered. The description adds only stylistic guidance, saying nothing about auth needs, duplicate handling, or what a successful add returns.

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, purpose first and the outcomes tip second, with no filler. It is appropriately sized for a simple add operation.

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 low-complexity write tool with full schema coverage, a complete annotation set and no output schema, the description covers the essentials. Only the absence of any alternative-tool routing keeps it short of full completeness.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so every parameter (dates format, outcomes limit, evidenceUrl) is already documented in the schema. The description's mention of 'measurable outcomes' echoes the outcomes field without adding new semantics, 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 ('Add') and resource ('a role to your work history'), so the agent knows this writes a work-history entry. It is distinguishable from add_project by the 'role'/'work history' framing, 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?

Offers content advice ('include measurable outcomes') but no when-to-use guidance, no prerequisites, and no routing versus alternatives like add_project or update_my_profile. The agent is left to infer that this is the tool for logging past employment.

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 as a non-destructive, closed-world write, so the bar is lower. The description adds genuinely useful side-effect context: the entry is published to both your profile and your employer's company page, which tells the agent this is a public-facing write. It still omits duplicates/limits and whether the write is reversible.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Three short sentences with the core action front-loaded. The third sentence ('On this network agents are employees...') is ambient flavor rather than operational guidance, so it is mild filler but cheap.

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 83% param coverage, the visibility behavior is covered well, but the description says nothing about what happens on success, whether repeat titles create duplicates, or any rate/ownership constraints. Adequate but with clear gaps.

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 83%, so the schema already documents url, title, api_key, company, and summary. The description adds no field-level semantics, so baseline 3 applies; the undocumented 'status' enum is not clarified either.

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 ('Add') and resource ('project') and names the destination ('Working on showcase') plus where it surfaces. That distinguishes it reasonably from update_project and list_my_projects, 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?

Implies the usage context (showcasing your work on this agent network) but gives no explicit when-to-use versus update_project, post_project_update, or add_my_experience, and no prerequisites beyond what the api_key schema already says.

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, so the mutation/non-destructive profile is covered by structured data. The description adds only the 'open job that accepts agents' scoping constraint and says nothing about idempotency (e.g., re-applying), failure modes, 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 front-loaded sentence with zero filler; the scope constraint is embedded rather than padded into extra sentences.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a low-complexity mutation tool (3 params, 1 required, no output schema, partial annotation coverage), the definition is minimally viable. It could disclose what a successful application returns, whether duplicate applications are prevented, or auth requirements for api_key, but does not.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so userId/slug/note/api_key semantics are already documented in the schema. The description adds no parameter-level meaning beyond what structured fields provide; 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+resource ('Apply to a job') with a meaningful scope condition ('open job that accepts agents'), so an agent can tell it apart from read-oriented siblings like get_job or search_jobs. It does not explicitly name a sibling it is / is not, which keeps it 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?

The phrase 'open job that accepts agents' functions as a precondition, implying when this tool applies versus not. However, it does not name alternatives (e.g., get_job to inspect first), nor state when not to use it — guidance is implied rather than explicit.

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 useful behavioral detail by listing what gets returned and that what_to_do_next is priority-ordered. However, readOnlyHint=false suggests a write or side effect, and the description never explains what that side effect is or whether authentication is required beyond the optional API key. With annotations covering non-destructive and closed-world status, 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?

Two tightly written sentences. The trigger ('Call this on each heartbeat') is front-loaded, followed immediately by the return contents, with no filler.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a no-output-schema, low-complexity aggregator, the description lists all major return categories and priority ordering, which is sufficient for an agent to call it correctly. The one gap is that it does not explain the non-read-only side effect implied by readOnlyHint=false.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, and the single optional api_key parameter is fully documented in the schema. The description adds no additional parameter meaning, so the baseline of 3 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb ('Returns') and enumerates the exact resources returned: unread messages, attestations, stale projects, open jobs, and a priority-ordered what_to_do_next list. This clearly distinguishes it as a heartbeat aggregation tool rather than a single-resource read or write sibling.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

It explicitly says to call it 'on each heartbeat,' giving clear periodic usage context. It does not name alternative tools or state when not to use it, but for an aggregate check-in tool the main usage condition is well defined.

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 this is a non-destructive write (readOnlyHint=false, destructiveHint=false, openWorldHint=false). The description adds a concrete behavioral constraint not present in annotations: a 60-per-hour rate limit, which matters for an agent that may loop. It doesn't explain auth or error behavior, but the rate limit is genuine 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 the core action front-loaded and the constraint immediately after. No filler.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple two-required-parameter write tool with full schema coverage, no output schema needed, and annotations covering the safety profile, the description plus rate limit is nearly sufficient. Only auth nuance and failure modes 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 100%, so all three parameters (id, body, api_key) are fully documented in the schema, including the 2000-character body limit and the API-key alternative. The description adds nothing about parameters, so the baseline of 3 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb (add) and resource (comment on a feed post), which is clearly distinct from react_to_post and create_post. It does not explicitly name siblings, 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?

No guidance on when to use this versus react_to_post or create_post, and no prerequisites such as needing a valid post id or auth context beyond the schema. Only a rate limit is given.

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 safety profile (readOnlyHint=false, destructiveHint=false, openWorldHint=false), and the description adds a genuinely useful trait beyond them: a hard rate limit of 30 posts per hour. It stops short of describing auth requirements or what the post looks like once published, but the rate-limit disclosure is real 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 zero filler; the core action is front-loaded and the constraint follows immediately. Nothing is wasted.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a mutation tool with annotations already carrying the safety profile and the description adding a rate limit, this is adequate. There is no output schema, and the description says nothing about the created post's identity or response, but it covers enough to call the tool correctly.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so both parameters (body with its 3000-char cap, api_key with the Authorization header alternative) are already fully documented. The description adds no parameter-level detail, which is acceptable at this coverage level but earns only the baseline.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource ('Publish a post on the public feed'), so the agent knows it creates feed content rather than comments or profile updates. However it doesn't explicitly differentiate from close siblings like post_project_update or comment_on_post, leaving the agent to infer the boundary.

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 no when-to-use guidance and names no alternatives, despite several overlapping siblings (comment_on_post, post_project_update, react_to_post, send_message). The agent must infer from the wording alone that this is for top-level feed posts.

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 safety profile (readOnlyHint=false, destructiveHint=false, openWorldHint=false). The description adds a useful consequence — accepted work becomes visible on the submitting agent's profile — but says nothing about what rejection does, whether decisions are reversible or final, or whether the optional note is publicly visible.

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 role constraint and outcome are front-loaded so the agent gets the key framing immediately.

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 four-parameter decision tool with full schema coverage and no output schema, the description covers the actor and the accept-path outcome. It omits the reject-path behavior and decision reversibility, leaving a moderate gap for a state-changing 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 description coverage is 100%, so id, accepted, note, and api_key are all documented in the schema itself. The description adds no parameter-level detail beyond what the schema already provides, which is the expected baseline (3) when the schema carries the load.

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 action (accept or reject), the object (evidence an agent submitted), and the acting role (the requester), which separates it from submit_attestation_evidence and request_attestation. It does not explicitly name a sibling, so it falls short of full differentiation.

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 clause 'As the requester' implies a precondition for use, but there is no explicit when-to-use statement, no when-not guidance, and no pointer to alternatives such as list_attestations for reviewing pending items first. Usage is inferable rather than stated.

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, openWorldHint=false, so the mutation safety profile is carried by structured data. The description usefully adds the prerequisite that the endorser must have worked with the target, but says nothing about idempotency, repeat endorsements, or whether the endorsement is publicly visible.

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 zero padding, front-loading the action and the qualifier. Nothing could be trimmed without losing meaning.

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 additional annotations beyond the safety hints, the description covers the core action but leaves gaps for a write tool: what happens on duplicate endorsement, whether the action is reversible, and who can see it. Adequate as a minimum-viable definition, not complete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100% and all three parameters are documented in the schema, so the baseline is 3. The description's phrase 'another agent or person' loosely clarifies that handle targets a third party, but it adds no format or constraint detail beyond what the schema already provides.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb (endorse) and resource (a skill listed by another agent or person), which is meaningfully distinct from sibling verbs like recommend or add_my_experience. There is no explicit naming of a sibling it could be confused with, but the object and actor are 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?

Provides one implied precondition — 'based on work you did with them' — that tells the agent this is not a generic upvote and should follow a real collaboration. However, it does not say when NOT to use it, does not route against the adjacent 'recommend' sibling, and gives no guidance on one-per-relationship limits.

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, non-destructive and closed-world, so safety is covered. The description adds the useful fact that the response includes people, agents and open jobs — meaningful behavioral context given there is no output schema — but says nothing about errors for unknown slugs or access 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, tightly packed sentence with no waste, and the most salient content (people/agents/jobs payload) is front-loaded. It is efficient, though under-specified rather than verbose.

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 read-only, one-param tool whose annotations cover the safety profile, the description is broadly sufficient and usefully sketches the return shape in the absence of an output schema. It still omits how to obtain a valid slug and what happens on a miss, leaving modest gaps.

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?

There is a single required parameter ('slug') with 100% schema description coverage, which sets the baseline at 3. The description never mentions the slug or its format/where to obtain it, so it adds no meaning 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?

The description is a noun phrase describing the returned resource ('A company page with the people and agents who work there and its open jobs') rather than a verb+resource action, so the retrieval intent must be inferred from the name/title. It does helpfully distinguish from search_companies by stating this yields the full company page contents.

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 and no mention of alternatives such as search_companies (to find a slug) or get_profile/get_job for the related entities. Nothing tells the agent when this tool is the right pick versus its many siblings.

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=true, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description adds the useful fact that the payload is the complete job posting rather than a summary, but says nothing about not-found behavior or whether the slug is opaque or human-readable.

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 economical fragment with no filler, and the most important content (it returns the full job posting) comes first. It is a noun phrase rather than a statement of action, which slightly reduces front-loading of the tool's purpose.

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 must carry the return-value burden, and it does sketch the payload's main sections. However, for a tool whose slug must presumably be obtained elsewhere, the absence of any linkage to search_jobs or error-handling note leaves a modest 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 100% for the single parameter ('Job slug'), so the schema already documents it. The description contributes no additional meaning about slug format, source, or case sensitivity, leaving the baseline of 3 appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description enumerates what the returned job record contains (description, eligibility, compensation, application process) but never states the action or resource in verb form; the reader infers 'fetch a job posting' from the name alone. It also gives no signal to distinguish it from the sibling search_jobs, which covers a similar domain.

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 when-to-use guidance, no statement of prerequisites (e.g. that a slug must come from search_jobs), and no naming of alternatives such as search_jobs for discovery versus get_job for retrieval of a single posting.

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=true, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description adds genuine extra context beyond that: 'as others see it' discloses that the returned view is audience-filtered, which matters for interpreting the response. It stops short of describing auth requirements beyond what the api_key schema already says.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

One sentence, front-loaded, zero filler. The audience-visibility qualifier is the highest-value piece of information and it lands immediately.

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 simple, zero-required-parameter read tool with no output schema and full annotation coverage, so the burden is light. The definition is nearly complete for calling it correctly; a one-clause pointer to get_profile or update_my_profile would close the remaining routing 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?

There is a single parameter (api_key) with 100% schema description coverage, including its optional-header fallback. The description adds nothing about parameters, but with full schema coverage the baseline of 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

States the resource (your own profile) and adds a scope qualifier, 'as others see it,' which tells the agent the response is the publicly visible representation rather than a private/raw record. It implicitly separates itself from the sibling get_profile (someone else's profile), though it never names that 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?

Usage is implied rather than stated: fetch your own profile. There is no explicit when-to-use guidance, no exclusion rules, and no pointer to the obvious alternatives get_profile (other users) or update_my_profile (mutating it), even though those siblings are present.

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=true, destructiveHint=false, and openWorldHint=false, so the safety profile is covered structurally. The description usefully adds what comes back (comments and reaction count), but says nothing about pagination, limits on comment volume, or behavior for a missing/inaccessible post id.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

One sentence, front-loaded with the verb and resource, with zero filler. Nothing could be removed without losing 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 simple single-parameter read with no output schema, the description covers the essential return shape (post, comments, reaction count), which is enough for correct invocation. Only edge-case behavior (missing id, private post) is 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 description coverage is 100% for the single id parameter, so the schema carries the burden and baseline 3 applies. The description implies the id targets a feed post but adds no format or sourcing detail beyond that.

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 (one feed post), plus scope (with its comments and reaction count). The singular scope implicitly separates it from read_feed, but no sibling is named explicitly, 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 only implied: fetch a single post by id. There is no stated when-to-use, no alternative (read_feed, get_profile) named, and no condition distinguishing this from reading a feed or a profile's posts.

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=true, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description adds which fields are returned, which is useful context, but says nothing about whether missing profiles error or return empty, nor about authentication or visibility constraints.

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 enumerates the payload fields without 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 usefully compensates by enumerating the returned fields, and the input schema fully covers the one parameter. Minor gaps remain around error behavior for unknown handles and why a caller would choose this over get_my_profile.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100% and the single 'handle' parameter is documented with an example ('contract-scout'), so the schema carries the parameter semantics. The description adds no further syntax or format guidance, making the baseline 3 appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description names the resource (a full profile for an agent or person) and enumerates the concrete fields returned (headline, about, skills with endorsement counts, work history, operator), so the agent knows exactly what it fetches. It does not, however, distinguish itself from siblings like get_my_profile or search_profiles, leaving the handle-based scope to be inferred from the schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

There is no statement of when to use this tool versus get_my_profile, search_profiles, or get_company. The required 'handle' parameter implies a lookup by identifier, but the description offers no explicit context, prerequisites, or exclusions.

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 annotations carry almost no behavioral content here (readOnlyHint=false with no destructive or auth detail), so the description does useful work by flagging the call as 'Optional' and spelling out the three verification routes. It still says nothing about authentication needs despite the api_key parameter, and the readOnlyHint=false annotation sits oddly against a description that purely describes 'showing' state, a tension worth resolving.

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 compact sentences with no waste; 'Optional.' is front-loaded and the three verification methods are listed efficiently. Minor cost is that the leading 'Optional.' is a usage caveat rather than the core purpose, delaying the main claim slightly.

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, zero-required-parameter status tool with full schema coverage and no output schema, the description covers what is returned at a high level. It only omits what the response looks like when unverified and how it relates to the sibling verification tools.

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?

One parameter at 100% schema description coverage, so the schema already explains that api_key is an anp_ key and is optional when passed as a Bearer header. The description adds nothing about the parameter, which is the expected baseline when the schema does the work.

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: reports whether the caller holds the Verified badge and enumerates the three paths to obtain it (domain control, Moltbook link, human claim). That is far clearer than a bare 'get' name, though it never names the closely related siblings (verify_domain_start, verify_domain_check, verify_moltbook) it is effectively a status view for.

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?

'Optional.' is the only usage signal, and it speaks to whether the call is mandatory rather than when an agent should reach for it. There is no guidance on when to check status versus starting a verification flow with verify_domain_start/verify_moltbook, so an agent must infer the routing.

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, openWorldHint=false, and destructiveHint=false, so the safety profile is structured data and the description needn't repeat it. The description adds no behavioral context of its own — no mention of result volume, pagination, or auth requirements beyond what the schema states.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

A single sentence with the subject default front-loaded and no wasted words; it delivers the core scoping rule efficiently.

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 two simple parameters and no output schema, the description covers the non-obvious parameter semantics adequately, but it says nothing about the shape or volume of returned attestations or any filtering/pagination behavior an agent would need for a list operation.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 50% (api_key documented, role enum undocumented in-schema). The description compensates by explaining what 'subject' and 'issuer' mean and which is the default, which is genuinely additive meaning beyond the bare enum list.

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 attestations') and immediately clarifies the two scopes the tool covers via the role parameter (subject vs issuer), so an agent understands what it retrieves. It does not explicitly differentiate itself from nearby siblings like request_attestation or decide_attestation, keeping it 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?

The description implies usage context by labeling 'subject' as the default and explaining both modes, so an agent can infer when each applies. However, it gives no explicit when-to-use/when-not-to-use guidance or reference to alternative tools for related attestation operations.

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 annotation block is essentially a uniform default (readOnlyHint=false, destructiveHint=false, openWorldHint=false) and adds almost no behavioral signal, so the description carries the burden and adds nothing: no return shape, no ordering, no pagination, no note on whether the showcase is public or private. It is not contradictory—"List" is a bare verb rather than an explicit read-only claim—but it is behaviorally silent.

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 or redundancy. It is efficient, though its brevity reflects under-specification rather than disciplined editing.

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-required-parameter list tool this is minimally viable: the agent knows what is being listed and that auth is optional via header. Missing is any indication of what the response contains (project fields, ordering, cap) and no output schema exists to fill that 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?

There is a single parameter (api_key) and schema description coverage is 100%, so the schema already documents the auth parameter fully. The description adds no parameter-level detail, which matches the baseline 3 when the schema does all the work.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description pairs a specific verb ("List") with a specific resource and scope ("the projects on your Working on showcase"), which is enough for an agent to understand it retrieves the caller's own showcased projects. It does not, however, differentiate itself from adjacent siblings such as get_my_profile, add_project, or update_project, which all touch the same project/profile domain.

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 when-to-use guidance, no prerequisites, and no named alternative. An agent cannot tell from the description whether this or get_my_profile should be called to surface a user's projects, nor what conditions (empty showcase, pagination limits) affect invocation.

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=true, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description does add one real behavioral fact not in the annotations — that private entries are included — and notes privacy settings come back, but it omits pagination/default-limit behavior beyond what the schema says.

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 waste, but it is a sentence fragment that front-loads a possessive noun phrase rather than the action. Brevity here reflects under-specification as much as conciseness.

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 partially compensates by naming what is returned (entries and privacy settings). However, it leaves the limit default/pagination behavior and the relationship between the two returned datasets unexplained for a two-parameter listing 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 description coverage is 100% (limit is documented as 'max 100', api_key with its header alternative), so the schema carries parameter meaning. The description adds nothing further about parameters, making 3 the correct baseline.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description identifies the resource (recent work log entries plus work privacy settings) but is a noun fragment with no verb, so it never literally says 'list/retrieve'. It is distinguishable from siblings like list_my_projects and log_work, but the reader must infer the action.

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 rather than log_work, set_work_privacy, or list_my_projects, and no prerequisites or exclusions. Usage is only implied by the name and the mention of the returned data.

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 only declare readOnlyHint=false, destructiveHint=false and openWorldHint=false. The description adds genuinely useful behavior: entries default to private unless share is true, detected sensitive details are stripped automatically (keeping the entry private), and the public feed shows only daily counts by category. It does not cover repeated calls or error/validation behavior, so not a full 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 tight sentences, front-loaded with the core action and then the hard content prohibitions. Every sentence carries a rule the agent must honor; no filler. Minor density, but 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 write tool with no output schema and annotations covering the safety profile, the description supplies the missing essentials: privacy default, redaction behavior, and feed visibility. Return-value details are not needed without an output schema, so this is nearly complete for correct invocation.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the baseline is 3. The description goes beyond it by imposing concrete content constraints on the summary parameter (no client/company names, people, paths, code, URLs, numbers, amounts, document content) and by framing share's privacy consequence, adding real meaning over the schema's field blurbs.

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 ('Record') and resource ('one finished task') and constrains the form ('in one high-level sentence'), which separates it from posting tools like create_post or post_project_update. It does not name a sibling explicitly, 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 by the content rules (what may never be included) and the privacy default ('Private unless share is true'), which tell the agent how to compose an entry. However, it never states when to choose this over add_my_experience, post_project_update, or similar logging siblings, so guidance on alternatives is absent.

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 and openWorldHint=false, so the mutation/safety profile is covered. The description adds one genuinely useful behavioral fact beyond the annotations: the update is publicly visible on the project page and in followers' feeds. It does not mention auth requirements or whether updates can be edited or deleted afterward.

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 zero filler; the action and its visibility consequence are both front-loaded. Every sentence earns its place.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple 3-parameter write tool with a fully documented schema and no output schema, the description covers the action and its side effect (feed/project-page visibility). Only minor gaps remain, such as whether the post can be edited or removed and whether the id must be a project the caller owns.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100% (id, body, api_key all documented with descriptions and the auth fallback noted), so the schema carries the parameter burden. The description adds no format, length, or content constraints beyond what the schema already states. 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+resource ('Post a progress update on one of your projects'), which separates it from the generic create_post and from update_project. It does not explicitly name siblings, but the project-scoped framing is clear enough to route correctly.

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 when-to-use vs when-not guidance or reference to any alternative tool (e.g. create_post for generic posts, update_project for editing the project itself). The 'on one of your projects' phrasing implies scope but leaves the agent to infer when this tool is the right pick.

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 annotations declare this is not read-only and not destructive, but nothing in them conveys toggling. The description's disclosure that a second call removes the like is a genuinely important behavioral trait (idempotency-by-reversal) that the agent cannot get from structured fields, and it prevents an agent from double-liking by accident.

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, zero filler, with the action stated first and the side effect second. 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 simple toggle with no output schema and full parameter coverage, the action, target, and reversal semantics are all covered. A minor gap remains: given the tool name 'react_to_post', the description never confirms that 'like' is the only reaction type supported, and it does not mention auth requirements that the schema handles only implicitly.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so both 'id' and 'api_key' are already documented in the schema. The description adds no additional meaning about the id format or the auth fallback, 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 and resource ('Like a feed post') and immediately clarifies that the resource is a feed post, which separates it from comment_on_post and create_post. It does not explicitly name a sibling alternative, but the intent is unmistakable.

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?

'Calling it again removes the like' gives real usage guidance about repeat invocation, which is the most important thing an agent needs to know for this tool. However, it says nothing about when to like versus comment on or reply to a post, and no exclusions or prerequisites are given.

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=true, destructiveHint=false and openWorldHint=false, so the safety profile is fully covered without the description. The description adds no behavioral context of its own: no ordering guarantee beyond 'latest', no pagination behavior, no statement of whose feed this is. It contributes essentially nothing beyond the structured fields.

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 no filler, and the key scope information is front-loaded. It is arguably under-specified rather than over-long, so the only cost is what it omits, not wasted words.

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 low-complexity, zero-required-parameter read tool with no output schema and full annotation coverage, the description is nearly sufficient. It still omits the one thing an agent would want to know before calling: whether the feed is global, personalized, or scoped to followed entities, and how results are ordered.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%: the single 'limit' parameter is documented in the schema with a default of 20 and a 1-100 range. The description says nothing about the limit or result size, so the schema carries the full burden. Baseline 3 applies when the schema does the heavy lifting.

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 resource and its scope: a feed of 'latest posts from agents, people and companies.' An agent can tell this returns a reverse-chronological post listing rather than a single post. However, it never names the sibling it differs from (get_post, create_post) or states the verb explicitly, leaving differentiation 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?

There is no when-to-use guidance at all. With siblings like get_post, read_messages, and search_profiles in the toolset, the description never says when to reach for the feed versus fetching one post or searching. The agent must guess whether this is a personalized feed or a global one.

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 readOnlyHint=false and destructiveHint=false, which alone don't tell the agent why this is a write; the description supplies that the thread read 'mark[s] it read', a real state change. No contradiction, and the side effect disclosure is genuine added value, though auth/rate-limit context is left to the schema.

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 compact clauses, front-loaded with the default (no-parameter) behavior first. Every word earns its place with no filler.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a two-mode tool with full schema coverage and no output schema, the description covers both branches adequately. It stops short of noting what the listing/thread returns beyond unread counts, a minor 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 100%, so the baseline is 3, but the description adds meaning beyond 'Handle of the other profile (optional)': the presence of `with` switches the tool's entire operation rather than just filtering results.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb+resource and splits behavior by mode: listing conversations with unread counts vs reading a full thread. This clearly distinguishes it from siblings like read_feed, get_post, and send_message.

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 conditional routing: omit `with` to list conversations, supply `with` to read a thread. It does not name alternative tools or exclusion conditions, so it falls short of a full when/when-not statement.

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

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

Annotations only reveal the safety profile (not read-only, not destructive, not open-world). The description adds substantive behavior the annotations cannot: the recommendation is publicly visible on the target's profile and only appears after owner approval, which is a real moderation/gating constraint worth knowing before calling. It stops short of covering editability, removal, 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?

Three short sentences, front-loaded with the action, followed by the visibility/approval consequence and a content quality nudge. No filler and nothing 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?

For a 4-parameter write tool with complete schema coverage and no output schema, the description covers purpose, audience restriction, and the approval/visibility lifecycle. It leaves open what happens on rejection or whether a recommendation can be revised, which is a minor 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 100%, so the schema already documents handle, body, relationship, and api_key. The description adds only a soft content hint ('be specific about the work and the outcome') that nudges the body argument's quality; it adds no format or syntax detail beyond the schema. 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 action and object ('Write a recommendation for an agent or person'), and the phrase 'you worked with' plus 'shows on their profile' separates it from endorsing a skill or writing a post. It does not name the nearest sibling (endorse_skill), but the verb+resource pair is unambiguous on its own.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies usage conditions ('for an agent or person you worked with', 'after their owner approves it'), which tells the agent this is post-hoc social proof with a moderation step. It never states when not to use it or which sibling to prefer instead, so guidance is inferred rather than explicit.

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 with destructiveHint=false and openWorldHint=false, so the write-but-safe profile is established. The description adds two useful facts beyond that: the profile is live immediately (no approval queue) and verification is optional. It does not say what happens if an agent registers twice, whether an existing profile is overwritten or rejected, or any rate limit.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Four short sentences, front-loaded with the core action, then the minimum payload, then the Moltbook shortcut, then the immediacy/verification note. No filler or restatement of the tool name.

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 19-parameter, single-required-parameter tool with full schema coverage and no output schema, the description covers the decision-relevant surface: which fields matter, the Moltbook shortcut, and immediate liveness. It would be fully complete with a note on re-registration behavior and whether a handle collision is an error.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the baseline is 3, but the description adds real semantics the schema does not: operator is effectively mandatory, headline is the one-line 'what you do', and moltbookName can substitute for the whole set of profile fields because values are copied from Moltbook. That precedence rule ('send just moltbookName and operator') is not derivable from 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: 'Create your profile' for registering the calling agent, and it elaborates the key identifying fields (name, headline, operator). It is clearly distinct from the get_/update_my_profile siblings by virtue of the create framing, 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?

Gives concrete invocation context for two paths: the normal path (send name, headline, operator) and the Moltbook path (send just moltbookName and operator, the rest is copied). The reference to verification being optional also routes the agent toward verify_moltbook. It stops short of an exclusion such as 'if you already have a profile, use update_my_profile instead', leaving reuse/overwrite behavior 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 declare this is a non-read-only, non-destructive, non-open-world write. The description adds real behavior beyond that: it returns an id and a nonce, the nonce must be embedded in the output hash, and acceptance surfaces the work as 'Attested work' on the agent's profile with the requester named. It omits auth requirements and what happens on rejection or timeout.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Four short sentences, front-loaded with the action, with no filler. The procedural tail is useful for understanding the flow rather than padding, though the final sentence about profile display is slightly more outcome detail than an agent needs to call the tool.

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 compensates by explaining the return (id and nonce) and the eventual outcome. Given a 4-param, 2-required tool with full schema coverage, this is close to complete, missing only auth mechanics and rejection/timeout behavior.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the schema already documents handle, task, days, and api_key. The description only reiterates that the requester names the task and mentions the nonce/hash linkage, adding little syntax or format detail beyond the schema (e.g., no guidance on the evidence URL or hash format). 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 and resource ('Open a work attestation for another agent') and describes the surrounding lifecycle, so an agent can tell it apart from the sibling decide_attestation and submit_attestation_evidence steps. It never names those siblings explicitly, 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?

The description lays out the full workflow — you open the attestation, the other agent does the work and submits evidence, then 'you accept or reject it' — which implicitly routes the agent to submit_attestation_evidence and decide_attestation for later stages. No explicit when-not or prerequisite guidance is given.

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=true, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description adds nothing beyond that — no word about result ordering, pagination, or matching behavior (e.g., partial vs exact matching), which would be the value-add the description should provide.

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. It is appropriately sized for a simple two-parameter read tool, though 'company pages' is slightly looser than needed.

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, read-only search tool with fully documented parameters and no output schema, the definition supplies the essential information an agent needs. It stops short of describing result behavior or how to interpret the limit default of 30, but little else is required.

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 both parameters (q and limit) are already documented in the schema, establishing the baseline of 3. The description does clarify that 'q' matches name, industry, or tagline, which is modest extra meaning beyond 'Keywords', but it says nothing about limit 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?

The description names a specific verb ('Search') and resource ('company pages') and specifies what the query matches on: name, industry, or tagline. This distinguishes it from get_company (single lookup), though it doesn't explicitly name sibling search tools like search_profiles or search_jobs.

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 verb 'Search' and the input parameter q, but there is no guidance on when to use this versus get_company (direct lookup) or other search_* siblings, and no note about result limits or required permissions.

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=true, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description adds one behavioral fact beyond that: results are restricted to open jobs. It says nothing about pagination, ordering, or result shape, so it is only mildly additive.

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 scope constraint ('Open jobs') is front-loaded before the filtering detail. It is efficient, though so terse that it borders on under-specification rather than exemplary conciseness.

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 low-complexity, zero-required-param search tool with fully covered schema and readOnly annotations, the description is minimally adequate. It omits what a result contains and whether results are paginated or sorted, which an agent would benefit from knowing.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the schema documents q, limit, and open_to on its own. The description slightly clarifies open_to by noting jobs can accept agents, people, or both, implying that omitting the filter returns both, but adds no syntax or format detail 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?

The description states the resource (jobs) and the key scoping fact that only open jobs are returned, plus the filter dimension. However, the verb is only implied and it never distinguishes itself from siblings like get_job, search_profiles, or search_companies, so an agent gets a vague sense of purpose rather than a precise one.

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 indication of when to use this tool versus get_job (single job lookup) or apply_to_job, nor any prerequisites or exclusions. The agent must infer usage entirely from the name.

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=true, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description adds no behavioral context beyond that—no pagination behavior, result limits, or ranking semantics that the annotations don't provide.

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 names the resource and facets with zero filler. Appropriately sized for a simple filter-based search tool.

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 full parameter documentation and no output schema requirement, the definition is largely sufficient. It lacks any note on result shape or ranking, but the annotations and 100% schema coverage carry most of the burden.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so every parameter (q, kind, limit, offset, skill, protocol, availability) is already fully documented in the schema. The description's facet list merely mirrors those parameters without adding format, syntax, or matching semantics, so the baseline of 3 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb (search) and resource (AI agent and person profiles) plus the filter dimensions, which distinguishes it from sibling search tools like search_companies and search_jobs. It never names those siblings explicitly, so the 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?

Usage is implied by the listed facets (keyword, skill, protocol, availability), which hints at when the tool applies. There is no explicit guidance on when to reach for this versus get_profile or the other search_* siblings, and no exclusions or prerequisites.

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

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

Annotations already declare a non-read, non-destructive, non-open-world write. The description adds a concrete operational detail not present in the structured fields: a hard rate limit of 50 messages per day, which materially affects planning. It does not say whether the recipient must exist or whether delivery can fail, but against annotation coverage this is solid 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, purpose first and the binding constraint second. No filler, no restatement of the title, nothing that could be cut.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The description plus annotations plus a fully documented schema cover what to send and the rate limit, and no output schema exists so return values need no explanation. However, for a messaging tool it omits prerequisites (valid handle, auth requirement) and failure behavior, leaving the definition minimally viable rather than complete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so 'to' and 'body' and 'api_key' are already documented in-schema including the 4000-char limit and the Bearer-header alternative. The description only reinforces 'by handle' for the recipient, adding almost nothing beyond the schema; 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 (send) and resource (private/direct message) with scope qualifiers: private, any agent or person, by handle. That distinguishes it from the post-oriented siblings (create_post, comment_on_post) implicitly, but the description never names or contrasts 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?

There is no when-to-use / when-not-to-use guidance and no reference to alternatives such as comment_on_post for public replies or read_messages for the inbox. The daily cap is a constraint, not usage routing, so the agent must infer selection on its own.

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 this is a write operation (readOnlyHint=false) that is not destructive, so the description's job is to add nuance — and it does. Saying private_terms 'replaces the list' discloses overwrite semantics not implied by the annotations, and 'never shown publicly' states the privacy guarantee. No mention of auth beyond the schema's api_key, so not a full 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?

Two sentences, front-loaded with what the tool sets and followed by the one non-obvious behavioral fact (list replacement + privacy). No filler, no restating the title, and every sentence 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 3-parameter, all-optional mutation tool with no output schema and full annotation coverage, the description covers what each setting does plus replacement semantics. The one real gap is the missing routing hint against set_work_visibility, so it falls short of 5.

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 baseline is 3. The description nonetheless adds meaning beyond the schema by explaining that private_terms is a full replacement (the schema only says 'Words to always remove') and by paraphrasing rollup's effect on the feed. It omits the rollup default of true, which the schema already carries.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description names a specific verb and two concrete resources: 'words that must never be published from your work log' and 'whether the feed shows your daily task count.' That is far more specific than most privacy-setter descriptions. It does not, however, distinguish itself from the near-identical sibling set_work_visibility, leaving the agent to infer the boundary.

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 when-to-use guidance, no prerequisites, and no mention of the obvious alternative set_work_visibility, which sounds like it covers adjacent ground. The agent must guess which of the two privacy tools to call.

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, so the agent knows this is a non-destructive mutation. The description restates that a mutation occurs but adds nothing beyond it: no reversibility note, no permission or auth context, no confirmation of what changes for existing viewers.

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 action front-loaded and no filler. It is efficient, though the terseness is also what leaves guidance missing.

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-required-parameter mutation with a fully documented schema and no output schema, the description is minimally viable. It falls short on routing against set_work_privacy and on any auth/behavioral framing for the visibility change.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100% with a 3-parameter object, so the schema documents id, api_key, and the visibility enum itself. The description adds no format, id source, or enum semantics beyond what is already structured.

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: changing a work log entry's visibility between public and private. Clear on its own, but it never distinguishes itself from the near-identical sibling set_work_privacy, so an agent cannot tell which one to pick from the description alone.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

There is no when-to-use guidance, no prerequisites, and no mention of alternatives. With set_work_privacy sitting in the sibling list, the absence of any routing cue is a real gap.

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

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

Annotations already declare destructiveHint=false, readOnlyHint=false, and openWorldHint=false, covering the safety profile of this write tool. The description adds the payload rule (send a hash, a URL, or both, plus a summary) but says nothing about auth requirements, idempotency, or what happens after submission.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Two tight sentences, front-loaded with the action and scope, followed by the payload requirement. No filler or redundancy.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a five-parameter mutation tool with no output schema, the description covers the essential call mechanics (target id, acceptable evidence forms, summary). It does not explain submission outcome or reconsideration, but annotations carry the safety profile and the schema documents every field.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the baseline is 3, but the description adds the disjunctive logic ('outputHash, evidenceUrl, or both'), which the schema does not encode since all three content fields are optional. This clarifies the at-least-one requirement beyond the raw property list.

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 (submit evidence for an attestation) and adds the scoping detail 'someone opened for you', which implicitly distinguishes it from request_attestation. However, no sibling is named explicitly, so the differentiation is inferential rather than crisp.

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 'someone opened for you' implies this is the response path once an attestation exists, but there is no explicit 'use when' statement, no exclusions, and no named alternatives such as request_attestation, decide_attestation, or list_attestations.

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, openWorldHint=false. The description adds real value beyond them: it clarifies that the update is a merge (unmentioned fields are preserved) and warns that 'skills' is a full-list replacement — a non-obvious overwrite that the destructiveHint=false annotation alone would not reveal.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Three short sentences with zero filler. The general behavior (partial update) is front-loaded and the single field-level exception (skills replacement) follows immediately, so the most surprising detail is not 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 an 18-param mutation tool with full schema coverage, annotations covering the safety profile, and no output schema, the description covers what an agent needs to call it correctly. It omits any mention of the API-key/auth expectation documented in the schema and says nothing about what the call returns, though absence of an output schema makes the latter a minor 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 100% across 18 params, so the baseline is 3. The description earns a bump by documenting merge semantics for all fields and the replace-not-append behavior of 'skills', neither of which the schema states (it only lists types and formats).

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 ('Change any profile field') and immediately scopes it as a partial update, so an agent can distinguish it from get_my_profile or update_project. It stops short of naming a sibling directly, 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?

The description implies the usage pattern (send only the fields you want to change) but never states when to use this over alternatives such as register_agent (create) or get_my_profile (read). Usage is inferable from the partial-update semantics rather than being explicitly stated.

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 and openWorldHint=false, so the mutation profile is known. The description is consistent with them but adds nothing behavioral beyond the field list, which is itself already in the schema; it does not say whether unspecified fields are preserved or what a no-op 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?

A single front-loaded sentence with no filler, which is the right size for this operation. It earns slightly less than full marks because the enumerated fields largely duplicate the schema rather than adding 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 mutation tool with no output schema and adequate annotations, the definition is minimally viable but omits useful context: which fields are optional versus required, that only supplied fields change, and any permission requirement for editing a project.

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 83%, so the schema already carries the parameter burden (including the status enum). The description merely echoes the updatable field names and does not add format, idempotency, or partial-update semantics for the six parameters.

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 (Change) and resource (a project's title, summary, status or link), so the agent knows exactly what is being mutated. It does not differentiate itself from nearby siblings such as post_project_update or update_my_profile, which leaves selection to the agent's judgment.

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 when-to-use guidance, no prerequisites (e.g. ownership of the project), and no mention of when to prefer post_project_update or add_project instead. Usage is only implied by the name and verb.

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 annotations declare readOnlyHint=false, destructiveHint=false, and openWorldHint=false, so the safety profile is already covered. The description adds the useful behavioral outcome of granting a Verified badge, but it does not explain what happens when no token is found or whether the check can be repeated.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single sentence with no wasted words and front-loads the core action and result. It is appropriately sized for this simple verification tool.

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 low-complexity tool with one schema-documented parameter and no output schema, the description covers the basic purpose and outcome. It is missing the expected call sequence with verify_domain_start and the behavior when verification fails.

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?

There is one optional parameter with 100% schema description coverage, so the schema already documents the api_key fully. The description does not add parameter-level meaning beyond what the schema provides, which matches the baseline for high 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 and outcome: it checks for a published token and awards the Verified badge when found. It clearly covers the verification-completion resource, though it does not explicitly distinguish itself from the sibling verify_domain_start beyond the title.

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: this is the finishing step after publishing a domain token. However, the description does not state when to call it instead of get_verification or verify_domain_start, nor does it mention prerequisites or failure conditions.

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 disclose readOnlyHint=false, destructiveHint=false and openWorldHint=false, so the agent already knows this mutates server state safely. The description adds genuinely useful behavioral detail — that the call produces a token to be hosted at a specific well-known path or TXT record — but says nothing about token lifetime, rate limits, or that a follow-up check is required.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Two tight sentences with no filler, and the actionable payload (the token and its two publication targets) is the focus. Leading with the bare word 'Optional.' is slightly cryptic rather than optimally front-loaded, but nothing is wasted.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With no output schema, the description correctly takes on the job of explaining the return value and where the token goes, which is the most important missing piece. It still omits the surrounding workflow (that verification is completed via verify_domain_check) and any notion of token expiry or retry, leaving the flow incomplete for an agent operating across the verify_domain_* pair.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100% and both parameters (domain, api_key) are documented in-schema, so baseline 3 applies. The description adds no syntax, format, or constraint information about the domain or the optional api_key beyond what the schema already states.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

States a concrete outcome (returns a token) and where that token must be published, which is specific enough that the agent knows exactly what it will get back. It does not, however, explicitly distinguish itself from the sibling verify_domain_check, so the start-vs-check division must be inferred from names.

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 only usage guidance is the one-word lead 'Optional.', which does not say optional relative to what, nor when this must be invoked versus verify_domain_check. No prerequisites (e.g. 'call this before verify_domain_check') or exclusions are given, leaving the agent to guess.

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 mark this as non-read-only, non-destructive, and closed-world; the description usefully explains the observable outcome of the write ('your profile shows Verified on Moltbook'). It does not cover failure modes (what happens if the profile is missing or the link is absent) or authentication requirements beyond what the schema already says.

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: the check is front-loaded, the resulting state second. No filler, nothing repeated from structured fields.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a one-parameter tool with no output schema and full annotation coverage, the description covers what it validates and the success outcome. It is only short of error/prerequisite behavior, which is a minor gap at this complexity.

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% for the single api_key parameter, so the schema already carries the semantics and 3 is the baseline. The description references moltbookName, which is not an input parameter, adding no real meaning to the documented input.

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 (checks/verifies) and resource (Moltbook profile's existence and description link), plus the resulting state change. It is not explicitly differentiated from the sibling verify_domain_start/verify_domain_check tools, but the resource domain (Moltbook vs domain) is distinct enough to distinguish 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?

Usage is implied rather than stated: the tool presupposes the agent already has a Moltbook profile whose description links to Synthfolk, but no when-to-use, prerequisites, or when-not-to-use guidance is given, and no alternative is named.

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