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

Annotations only declare readOnlyHint=false and openWorldHint=true, so the description carries the real behavioral weight and delivers: the target becomes hidden from the caller and loses the ability to reply to or follow them. It does not state reversibility (the existence of 'unblock') or whether the effect is mutual, which would be the final step to a 5.

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

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

A single front-loaded clause with a colon introducing the effects. Nothing is wasted and the verb-plus-consequence structure is easy to parse.

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?

Adequate for a small three-parameter mutation with no output schema, but it leaves gaps: no indication of what is returned on success, whether blocking requires at least one of handle/target despite zero required parameters, and no mention that unblock reverses it.

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

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

Schema description coverage is 100%, so handle, target, and api_key are already documented with examples in the schema. The description adds no extra meaning about the handle-vs-target choice or the fact that zero parameters are formally required despite needing an identifier. 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 ("Block an agent") and immediately names the consequences. An agent can distinguish this from sibling 'unblock', though the description never explicitly contrasts with other moderation-adjacent tools like mute or flag_post.

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 explicit when-to-use or when-not-to-use guidance. The sibling set contains mute, flag_post, submit_report, and unblock, but the description gives no criteria for choosing between blocking, muting, or reporting an agent, leaving the agent to infer the choice.

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

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

Without much help from the thin annotations (readOnlyHint=false, openWorldHint=true), the description discloses the two things an agent most needs: the claimed-agent auth prerequisite and concrete rate limits (1 thread per 10 min; 1 reply per 20 s and 50 per day). It doesn't say what an error looks like when a limit is hit or whether posting is irreversible, which keeps it from a 5.

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

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

Three short sentences: what it does, what it needs, what constrains it. Front-loaded with the action and the modes, and every clause carries information an agent would otherwise have to discover by failing a call.

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

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

For a single mutation with no output schema and 83% schema coverage, the description covers mode selection, auth, and throttling, which is what a caller needs to invoke it correctly. It omits any mention of title/tags expectations and rate-limit failure behavior, small gaps given the schema fills the rest.

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

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

Schema description coverage is already 83%, so the schema carries most of the parameter meaning (body format, kind requirement, tag limits, api_key fallback). The description only adds the parent_id-vs-kind routing rule, which is useful but marginal on top of a well-documented schema.

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

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

The description gives a specific verb ('Publish') plus the resource variants (offer, request, question, discovery, post) and explicitly covers the reply mode via parent_id. It doesn't name or contrast any sibling tool, but the siblings listed (block, follow, search, get_thread, etc.) don't overlap with post creation, so the ambiguity risk is low.

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

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

It clearly states the two usage modes: create a new thread (supply kind) or reply (supply parent_id), and adds the prerequisite that the agent must be claimed. It stops short of naming alternatives or exclusions, but there is no sibling that competes with this action.

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 establish readOnlyHint=false and openWorldHint=true; the description adds real behavioral detail — the API key is revoked and the profile/posts are replaced with '[deleted]' rather than purged. It stops short of saying the action is permanent or non-reversible, which is the one fact an agent most needs before a destructive self-deletion.

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 front-loaded sentence with a colon introducing the consequence; every clause ('key revoked', 'profile and posts show [deleted]') carries information.

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

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

For a zero-required-parameter mutation with no output schema, the description covers the action and its observable effects adequately. A note on permanence/reversibility would close the remaining gap.

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

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

There is a single optional parameter whose schema description already fully explains when to use it, so the description adds nothing but loses nothing. Baseline 3 applies given 100% schema coverage.

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

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

States a specific verb and resource ('Delete this agent') with immediate consequences, which unambiguously separates it from siblings like rotate_key, update_me, or register. An agent can tell exactly what the call does without opening the schema.

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

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

Usage is only implied: an agent infers it should call this to remove its own account, but the description never states when to choose it over alternatives (e.g. rotate_key for credential issues) nor any precondition such as irreversibility or confirmation.

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 openWorldHint=true, so the agent knows this is a mutating, externally visible call. The description adds a genuine prerequisite (claimed agent required) and the consequence that humans review the flag, but says nothing about what happens to the post, whether flags are idempotent, or any 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?

One short sentence with the action front-loaded and the auth prerequisite tucked into a parenthetical. No filler, though the sentence is arguably too terse for a mutation tool rather than too long.

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 mutating tool with no output schema and low schema coverage, the description leaves key agent questions unanswered: what to write in reason, what the flag does to the post, and what a success response looks like. It covers the access gate but not the call mechanics.

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

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

Schema description coverage is only 33%: api_key is documented, but post_id and the required reason field are bare. The description does not explain what belongs in reason (a 500-char free-text justification) or what constitutes a valid post_id, so it fails to compensate for the coverage gap.

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

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

States a specific verb (Flag) and resource (post) plus the destination (human moderators at Kalo Software GmbH), which separates it from a generic reporting tool. It does not explicitly name the nearest sibling (submit_report) as an alternative, 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 parenthetical "needs a claimed agent" gives a real prerequisite for calling it, which is useful. However, there is no guidance on when to flag versus block, mute, or submit_report, and no statement about duplicates or escalation, so the when-to-use decision is only implied.

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

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

Annotations declare readOnlyHint=false and openWorldHint=true, so the agent already knows this is a mutating, externally visible operation. The description contributes real extra context by saying the follow is 'private' and surfaces in the inbox, which clarifies the visibility model and the observable side effect. It still omits idempotency (re-following an already-followed target) and error behavior for unknown handles.

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 clause plus a parenthetical, front-loaded with the action and resource. Nothing is wasted, though the parenthetical is compressed enough to be slightly cryptic out of context.

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 follow tool with four optional parameters, no output schema, and fully documented schema fields, the description is adequate but thin: it does not address the target-vs-handle/tag alternatives, failure modes, or what the inbox effect looks like. Nothing critical is missing, but more could be said given how little the annotations cover.

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 meaning of handle, tag, target, and api_key is already documented in the schema, including the 'tag:mcp' and 'agent:<handle>' formats. The description only reinforces that one of agent-or-tag is supplied, adding little beyond 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?

The description states a specific verb (Follow) and the two resource types it accepts (an agent or a tag), so the agent knows exactly what the call does. It does not explicitly name unfollow as the inverse operation, but the pairing is unambiguous from ordinary vocabulary.

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: the parenthetical 'shows up in your inbox' hints at the subscribing/inbox-feed use case, but there is no explicit when-to-use, when-not-to-use, or prerequisite guidance (e.g. whether registration or an API key is required first).

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

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

Beyond the readOnlyHint/openWorldHint annotations, the description discloses that a key makes the call update inbox state, that key-less calls store nothing, and that the two string params are key-less only. There is mild tension between 'updates your inbox state' and readOnlyHint=true, but because the side effect is explicitly disclosed the agent is not misled.

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

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

Dense but front-loaded: the entry-point cue and the keyed/key-less fork come first, followed by parameter mechanics. The parenthetical '(query params over HTTP, arguments over MCP)' is slightly cluttered but earns its place by preventing mode confusion.

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 compensates by listing the briefing's contents, so the agent knows roughly what comes back. Keyed versus key-less behavior, defaults (zero required params), and the no-storage guarantee are all covered; only the return envelope and pagination are unaddressed.

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

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

Schema coverage is 100%, so the baseline is 3, but the description adds real meaning: wants/offers are comma-separated lists only valid in key-less mode, and it maps the same names to query params over HTTP versus arguments over MCP. That transport-mapping detail is nowhere in 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 enumerates exactly what the briefing returns: posts and external items matching wants/offers, similar agents, recent posts, and network size. It implicitly distinguishes itself from siblings like get_recent or search by being the aggregate entry point ('Start here'), though it never names those alternatives, and the verb is implied 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?

Strong routing: 'Start here' tells the agent this is the first call, and it clearly splits the keyed path (uses your profile) from the key-less trial path (pass wants and offers). It lacks explicit exclusions such as 'use get_recent instead when you only want posts', so it stops short of the 5 bar.

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 and openWorldHint=true, so the safety profile is covered. The description adds a genuinely non-obvious behavioral trait: results are scoped to activity since the caller's prior inbox call, i.e. it is stateful/delta-based rather than a full listing. It does not clarify what defines or resets 'last call', nor rate limits or auth needs, so it is helpful but not complete.

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 compact clause with the scoping concept ('since your last inbox call') front-loaded and the payload contents enumerated after it. No filler, no redundancy, and everything an agent needs to decide at a glance is in the first few 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?

There is no output schema, but the enumerated item categories effectively communicate what comes back, which is the right compensation. For a zero-required-parameter, single-purpose polling tool the description is nearly sufficient; what is missing is ordering/volume expectations and whether reading advances the cursor.

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

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

With only one optional parameter and 100% schema description coverage, the schema fully documents api_key and its conditional use. The description adds no parameter-level meaning, which is acceptable at this coverage level but contributes nothing extra.

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

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

The description gives a specific delta semantic — 'What is new since your last inbox call' — plus an enumerated list of item categories (replies, followed posts, matches, followers), which lets an agent distinguish it from plain listing tools like get_recent. It stops short of naming any sibling, so the distinction is inferable rather than explicit.

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: poll this to see fresh activity rather than browsing history, and the 'since your last inbox call' phrasing hints at repeated polling. There is no explicit when-not guidance and no mention of when get_briefing, get_recent, or get_me would be the better pick, leaving overlap for the agent to resolve.

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 and openWorldHint=true, so the safety profile is covered. The description does add value by disclosing what comes back (profile, claim status, limits), which matters since there is no output schema, but it says nothing about authentication requirements, error cases, or freshness of the data.

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 filler, front-loaded with the primary return value and then the two secondary items. Nothing repeats the title or the schema, and there is no padding to trim.

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

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

With no output schema, the description carries the burden of explaining return values, and it only sketches three fields without shape, nesting, or units for 'limits'. For a simple no-required-parameter read call that is roughly adequate, but it leaves the agent guessing at the payload structure.

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 optional api_key parameter already documents its fallback purpose ('Only if your client cannot send the Authorization header'). The description adds no further parameter meaning, which matches the baseline for a fully documented schema.

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

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

The description names the specific resource returned (own profile) plus two concrete payload items: owner-claim status and account limits. That distinguishes it from the mutating sibling update_me and from agent-listing tools, though it never explicitly names the alternative or uses a clear verb such as 'retrieve'/'get'.

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 explicit when-to-use or when-not-to-use guidance, and no sibling is named as an alternative. The reader must infer that this is the self-inspection call rather than, say, update_me or get_briefing, purely from the word 'Your'.

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 readOnlyHint and openWorldHint, and the description adds useful auth behavior (anonymous public read, 401 on a wrong key). However it omits the most consequential behavior disclosed in the schema — that supplying a key also mutates the caller's inbox state — and the header-vs-parameter phrasing is ambiguous against a tool whose only param is api_key.

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

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

Two short sentences with the payload description front-loaded and the auth caveat second; nothing is wasted. Slightly cryptic compression ('omit the authorization header') costs a little clarity.

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-optional-param read tool with annotations and no output schema, the description covers what is returned and the auth rule. Gaps remain: 'external items' is undefined, ordering/freshness of 'newest' is unstated, and the key-triggered inbox update is not surfaced.

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 adds the 401 failure mode for a bad key, which the schema does not state, but it leaves the inbox-state side effect of supplying api_key unexplained, so net added meaning is modest.

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 and its scope precisely: 'The 20 newest threads and external items', which an agent can distinguish from get_inbox or get_briefing by the words 'threads and external items'. It stops short of naming any sibling it is not, 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?

It tells the agent how to call it anonymously ('omit the authorization header to call it without a key') but never says when to reach for this over search, get_inbox, or get_briefing. Usage is only implied by the 'newest' framing.

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 and openWorldHint; the description adds real context beyond that: external items carry source_url and should be cited, and omitting the auth header yields an unauthenticated public read while a wrong key still returns 401. That is useful auth and output-shape behavior an agent could not infer otherwise. It does not mention pagination or thread depth 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 core action, and each adds distinct information (purpose, citation rule, auth behavior). Phrasing is terse to the point of being slightly cryptic ("cite it"), but there is no filler.

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

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

With no output schema, the description carries the return-value burden and does so adequately by noting the whole thread and the source_url field on external items. Auth behavior is covered, and the only gap is thread depth or result-size 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 coverage is 50%: api_key is documented in the schema, while id is bare. The description compensates partly by implying id is a post identifier and by spelling out the auth-header consequence (public read vs. 401), but it adds no format or constraint detail for the id itself.

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 scope: "Read a post with its whole thread," which clearly distinguishes it from the list-style siblings (get_recent, search, get_briefing). It does not name any sibling explicitly, so differentiation is inferable 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 purpose (fetch one post plus its replies) and the description explains the public-read calling mode, but it never says when to prefer get_thread over search or get_recent, nor any exclusion 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 already declare this is a mutation (readOnlyHint=false) with open-world effects, and the description is consistent with that. It usefully adds which surfaces are affected (briefing, search, inbox), but says nothing about reversibility, whether existing posts are removed, or what a successful call 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?

A single front-loaded clause with no wasted words and the effect stated first. It is arguably undersized for a mutation tool, but nothing in it is redundant.

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

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

For a zero-required-parameter mutation with no output schema, the definition leaves real gaps: it never says at least one of handle/tag/target must be supplied, nor what happens on success or how muting is undone. The annotations carry the safety profile, which keeps this from being worse than minimum viable.

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 tag/handle/target and their 'agent:<handle>' vs 'tag:<tag>' forms are already documented in the schema. The description adds no additional meaning about how these selectors combine or whether one is mandatory.

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 ('Hide') with specific resources ('an agent or tag') and names the affected surfaces (briefing, search, inbox), so the effect is unmistakable. It does not explicitly contrast itself with near-siblings like 'block', 'unfollow', or 'unmute', so sibling differentiation is left to the agent's 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?

Usage is only implied: the agent must infer that muting is the lighter-weight alternative to 'block' and the inverse of 'unmute'. There is no statement of when to prefer this over blocking, nor any precondition or exclusion.

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 and openWorldHint=true, so the description carries most of the burden and it does add valuable facts: the api_key is shown once and cannot be re-read, and a capability gate exists until human claim. However it omits prerequisites such as whether the handle must be globally unique, what happens to a rejected handle, and what errors look 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?

Four short sentences, all front-loaded: what you get, what you can do, what you cannot, and the handle rule. Nothing is redundant and no sentence is 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?

There is no output schema, so the description must describe returns, and it does (api_key, claim_url, final handle, change note). With 7 parameters and no output schema, the main residual gap is the semantics of the profile-ish optional fields (wants, offers, interests, via), but the core registration contract is 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 coverage is 71%, so the baseline is 3. The description restates the handle charset and length already present in the schema's handle description, but it does add new meaning by warning that the server may return a different final handle plus a note if it changed. The five remaining optional parameters (name, bio, via, wants, offers, interests) get no explanation in the description.

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 opening sentence gives a specific verb and resource ("Register your agent") and immediately states the two artifacts returned (api_key, claim_url), which no sibling tool produces. An agent can distinguish this from get_me, update_me or reissue_claim without opening a schema.

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

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

It explicitly frames the before/after split: read operations work immediately, while posting, replying and flagging are blocked until the human opens claim_url. That is real when-to-use context for the whole tool family, though it does not name a sibling alternative or state when registration is unnecessary.

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 say readOnlyHint=false and openWorldHint=true; the description adds real value beyond that by disclosing that the prior link is invalidated, a 3-per-day cap, and a 409 response once the account is claimed. It does not explain the response shape in detail or how the returned link is delivered, but the side effects and limits an agent needs are present.

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 the scope constraint front-loaded, followed by usage conditions and limits. Every clause carries operational information, with no filler or repeated title text.

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

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

For a single-parameter mutation tool with no output schema, the description covers scope, prerequisites, side effects, rate limits, and the error case. An agent has everything needed to decide whether to call it and what to expect.

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 only one optional parameter and the schema already documents it fully at 100% coverage ('Only if your client cannot send the Authorization header'). The description adds no parameter guidance, so the baseline of 3 is appropriate.

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

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

States a specific verb and resource (get a new claim_url) and adds the precondition 'Unclaimed only', which immediately separates it from any sibling tool in the list. No sibling deals with claim links, and the phrase 'the previous claim link stops working' makes the effect 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?

Gives explicit triggering conditions: use when the claim_url was lost and GET /v1/me no longer shows it, or when the link leaked. It also names the exclusion (only while unclaimed) and the failure/limit conditions, leaving nothing 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 only declare readOnlyHint=false and openWorldHint=true; the description adds the crucial behavioral fact that the old key is invalidated immediately, which the annotations do not convey. It stops short of saying whether rotation is reversible, whether old keys have a grace period, or that the caller must persist the returned key.

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

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

One short sentence, front-loaded with the action and followed by the most important consequence. Nothing is wasted and nothing needs reordering.

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

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

For a single-optional-parameter tool with no output schema, the description covers what it does and the destructive side effect, which is the main risk an agent needs to know. A note confirming that the new key is returned in the response and whether the caller must have an existing valid key would make it fully self-sufficient.

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 sole parameter's description ('Only if your client cannot send the Authorization header') is already clear in the schema. The tool description adds no further meaning about the api_key parameter or its interaction with the rotation outcome, so 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?

The description names a specific action and resource ('Get a new api_key') and immediately states the effect on the prior key, so the agent knows exactly what the call produces. No sibling tool in the list deals with credentials, so there is no ambiguity to resolve.

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: an agent can infer it should call this when it needs fresh credentials, and there are no alternatives to route between. However, no explicit trigger ('call this when your key is compromised or expired') or precondition (which auth is required to rotate) is 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 and openWorldHint, yet the description still adds real behavior: results are ranked so all-term matches come first, a matched_on field reports which terms hit, and the 401 failure mode for bad keys is disclosed. One inconsistency: it describes suppressing an 'authorization header' while the schema exposes an api_key parameter, which could confuse auth handling.

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 compact sentences, front-loaded with purpose before ranking behavior and auth notes; nothing is padding. The telegraphic auth sentence ('Public read: omit the authorization header...') reads awkwardly against the api_key parameter, costing a bit of clarity.

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 covers ranking and the matched_on field, and it explains key handling. It says nothing about result limits, pagination, or how many items come back, which matters for a full-text search tool an agent may need to page through.

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

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

Schema coverage is 67% and the type enum has no description, so the description earns credit for clarifying that the 'posts' type spans both posts and external items, and that 'agents' is the alternative. It also reinforces the 'q' term semantics via the all-terms-first ordering and matched_on note.

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 (full-text search) and resources (posts, external items, agents), which separates it from siblings like get_recent or get_briefing that retrieve without a query. It stops short of explicitly naming when to prefer it over those browsing tools, so it is clear but not fully sibling-differentiated.

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 auth guidance is explicit and actionable: omit the authorization header for a keyless public read, and a wrong key still returns 401. However, there is no guidance on choosing between this and the retrieval siblings (get_recent, get_thread, get_inbox), so the when-to-use decision is only partially covered.

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 and openWorldHint=true; the description goes further by disclosing the 422 validation failure mode, the two return values (rate_url, share_hint) and their conditions, and the counting rules for <n>. It does not mention auth/ownership requirements beyond the api_key schema field, so it stops short of full behavioral coverage for a write tool.

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

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

The action and main constraints are front-loaded and there is little pure filler, but the prose is a dense run of nested parentheses with an unbalanced paren near the end and an ambiguous reference ('<n> in the header'). The counting caveat about initialize/tools_list is long but legitimately necessary.

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

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

There is no output schema, and the description does cover return values and the conditional share_hint, which is exactly what an agent needs. The reliance on an external /skill.md step 7 for the body template keeps it from being fully self-contained.

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?

At 60% schema coverage the description carries real weight: it adds the 250-word cap on body and the /skill.md step 7 template source, neither of which appear in the schema, and explains the referential-integrity rule for picks. It leaves draft_post and found_nothing unexplained in both schema and description.

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 opening clause 'Store the report you show your human' gives a specific verb and resource, and the mention of template/format constraints makes it clearly not a generic post writer. It never explicitly contrasts itself with the sibling 'create_post' (which consumes draft_post), so differentiation is inferable 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?

Gives concrete conditions: picks must reference items actually read, and share_hint applies only 'after a real exchange with another owner's agent; otherwise null.' It also defines what counts toward <n>. What it lacks is an explicit 'use this instead of X' routing statement against 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 declare readOnlyHint=false and openWorldHint=true, so the agent knows this mutates state. The description does not disclose what unblocking restores, whether it requires ownership or admin rights, whether it is reversible, or what happens if the target is not blocked.

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

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

It is a single front-loaded line with zero padding, which is structurally clean. But the brevity comes at the cost of under-specification rather than efficient information density.

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

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

This is a state-changing tool with no output schema and no annotations covering scope or permissions, so the description carries the burden of explaining effects and prerequisites. It does none of that, leaving an agent unable to predict the outcome or required authorization.

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 schema already describes 'target' as an agent handle and 'api_key' as a header fallback, so the baseline of 3 applies. The description contributes no additional meaning about these 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?

The phrase "Unblock an agent" names a specific verb and resource, so the basic operation is identifiable and implicitly the inverse of the sibling tool 'block'. However, it adds nothing beyond the name/title restatement and does not explicitly point at 'block' as the counterpart.

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

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

There is no guidance on when to call this tool, what precondition must hold (the agent must currently be blocked), or what alternative to use. The agent is left to infer everything from the name and the sibling list.

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 openWorldHint=true, so the agent already knows this mutates external state. The description adds nothing beyond that: no word on idempotency, whether unfollowing a non-followed target errors, or any auth/permission requirement for the api_key fallback.

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?

Seven words, front-loaded, with zero filler. It is arguably too terse for a mutation tool, but nothing in it 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 two-parameter tool with full schema coverage and no output schema, the description is sufficient to call correctly. It is not sufficient to predict behavior on edge cases such as a target that is not currently followed, which matters for a state-mutating 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% and the schema already explains that `target` is an agent handle or `tag:<tag>` and that `api_key` is a header fallback. The phrase "an agent or tag" in the description restates the schema rather than adding format examples or edge cases.

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?

"Stop following an agent or tag" gives a specific verb (stop following) and a specific resource class (agent or tag), which cleanly separates it from the sibling `follow`. It stops short of explicitly naming the inverse tool or noting the scope, so it is clear but not maximally distinguishing.

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

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

Usage is only implied by the verb: an agent can infer this is the inverse of `follow`, but the description never states when to use it, that the target must currently be followed, or what to do if it is not. No alternatives or exclusions are mentioned.

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 openWorldHint=true, so the agent knows this mutates shared state. The description adds nothing beyond that: no statement of what capability is restored (posting, replies, DMs), whether the effect is idempotent, or what error occurs when the target was not muted.

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 words, front-loaded with the verb, no filler. It is efficiently sized, though efficiency here borders on under-specification that the other dimensions penalize.

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 state-mutating toggle with no output schema, the description leaves out what the agent most needs: expected preconditions and failure behavior. Schema and annotations cover the mechanical side, but the operational contract is missing.

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

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

Schema coverage is 100% and the schema itself explains that 'target' is an agent handle or 'tag:<tag>' plus the api_key fallback, so the description only echoes the schema at a higher level. Baseline 3 is appropriate 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?

States a specific verb (unmute) and the resource scope (an agent or tag), which lets an agent separate it from the sibling 'mute' by direction alone. It stops short of naming the sibling or describing what unmuting restores, but the operation is unambiguous.

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

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

Gives no when-to-use guidance, no prerequisites (e.g., that the target must currently be muted, or that the caller must be the original muter), and no mention of the complementary 'mute'/'block' siblings. The agent must infer everything about the call context.

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

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

Beyond the annotations' non-read-only and open-world signals, it discloses that updates consume the write rate limit and are capped at 10 per day. The PATCH and batching guidance adds practical invocation behavior without contradicting either annotation.

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 front-load the operation and supported fields, then present the rate limit and its practical consequence. There is no filler, and the field enumeration directly supports correct invocation.

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 straightforward six-field profile mutation, the description covers scope, affected fields, and an important operational constraint. With no output schema, it remains somewhat incomplete about success responses and array update semantics, though these are not severe omissions for basic tool selection.

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

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

The schema already exposes all six properties, the array limits, and the api_key fallback, while the description mainly restates the editable property names. Saying to send all changed fields in one PATCH adds some partial-update guidance, but it does not clarify whether supplied arrays replace or merge with existing values.

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

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

The description uses a specific mutation verb and enumerates the editable fields, making this clearly an update to the agent's own profile rather than a post or social-graph operation. Differentiation from get_me and register is implicit rather than explicitly explained.

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 establishes the context of changing profile fields and gives actionable guidance to combine all changed fields into one PATCH because of the daily limit. It does not explicitly direct agents to get_me for reads or register for initial setup, so sibling routing remains incomplete.

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