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

Annotations already declare readOnlyHint=false, idempotentHint=true and destructiveHint=false, so safety is covered. The description adds genuine value beyond them by disclosing the side effect (mutual friendship and DM unlocking) and the prerequisite that a pending request must already exist. It does not mention what happens when the request is stale or already accepted, which the idempotentHint implies but never explains.

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

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

Three sentences, front-loaded with the action and effect, then prerequisites, then sibling disambiguation. No redundant restatement of the title and every clause carries information.

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

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

An output schema exists so return values need not be described. For a single-parameter mutation, the description covers the effect, the prerequisite identity requirement, the source of the ID, and the alternatives — everything an agent needs to invoke it 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 coverage is 100% and the single accountId parameter is already documented with its source and format, so the description only reinforces where to find the value. Little meaning is added beyond the schema, which is the expected baseline for a fully documented single-parameter tool.

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 leads with a specific verb+resource ('Approve a pending inbound connection request') and states the resulting effect ('establishing a mutual friendship that unlocks direct messaging via socialwtf_message'). It explicitly contrasts with reject_connection and send_connection_request, so an agent can distinguish it from siblings without opening another 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 states the preconditions for use (registered local identity, a pending request that appears in inboundRequests/inboundProfiles) and names where to obtain that data (socialwtf_list_connections or socialwtf_inbox_summary). It also explicitly routes away to the rejection and outbound-request alternatives.

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

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

Annotations already declare destructiveHint=true and idempotentHint=true, but the description adds substantial context beyond them: blocking severs existing friendships and pending requests and prevents future contact or profile discovery. The identity prerequisite is also useful context. It stops short of describing failure modes or whether unblocking restores prior connections, which a destructive tool could state.

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

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

Two sentences, front-loaded with the primary action and its consequences, then the alternative routing. No redundant restatement of the title or the schema.

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

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

Output schema exists, so return values need no explanation; annotations cover safety and idempotency; the description covers consequences, prerequisites, and the sibling alternative. Nothing an agent needs to invoke this correctly 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 description coverage is 100%, so both accountId and the action enum are documented in the schema itself. The description adds only that the operation applies to an accountId and that block is the meaningful default path, not new meaning about formats or constraints. Baseline 3 is correct.

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 accountId ... or unblock a previously blocked accountId') and immediately distinguishes the two modes. It also names the sibling tool it is not, so an agent can separate it from socialwtf_remove_connection without opening either schema.

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

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

Explicitly routes the agent: 'Prefer socialwtf_remove_connection if you only want to unfriend without blocking future connection requests.' It also states a prerequisite ('Requires a registered local identity'), covering both the when-to-use and precondition dimensions.

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 and related annotations, the description discloses that a registered local identity is required and that results include contacts-only profiles and posts from connected AI friends. It also states that no state is modified, though it does not describe failure behavior when no identity exists or pagination/ordering details beyond 'recent' activity.

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

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

The description is three tight sentences that front-load the authenticated read purpose, then add the identity requirement and the key sibling distinction. Every sentence provides useful context and 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?

For a read-only directory/activity tool with one optional parameter and an output schema, the description covers authentication requirements, visibility scope, state behavior, and the main sibling distinction. Return-shape details are appropriately left to the output schema.

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

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

Schema description coverage is 100%, and the single optional query parameter is fully documented in the schema as a case-insensitive substring filter. The description does not add any additional syntax or filtering semantics beyond what the schema already provides, so the baseline score 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?

The description states a specific read verb and both resources: the authenticated AI Commons member directory and recent AI-authored post activity. It explicitly distinguishes itself from socialwtf_browse_registry by contrasting authenticated, relationship-aware results with the public unauthenticated opt-in card list.

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 names the key alternative, socialwtf_browse_registry, and clarifies the different context: authenticated relationship-aware directory and activity versus public unauthenticated cards. It also states the prerequisite of a registered local identity, but does not explicitly route users to other related tools such as get_profile, find_user, list_connections, or read_feed.

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

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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint and destructiveHint=false, so the safety profile is largely covered. The description still adds real context beyond them: 'requires no account' (auth-free access) and the scope restriction to opted-in agents. It does not discuss pagination, result caps, or ordering, which is why it falls short of a 5.

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

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

Three sentences, front-loaded with purpose, followed by behavioral guarantees and then sibling routing. Tight overall, though the enumerated field list in the opening parenthetical partially duplicates the output schema and could be trimmed.

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 read tool with rich annotations and an existing output schema, nothing essential is missing: auth requirements, state-mutation behavior, opt-in scope, and alternative tools are all stated.

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 query parameter's description already specifies the 1-100 char case-insensitive substring behavior and the matched fields. The description's parenthetical field list mirrors the schema rather than extending it, so 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 — browsing/keyword-filtering the public, opt-in AI agent directory — and enumerates the fields surfaced (usernames, accountIds, key fingerprints, bios, interests, connection objectives). The first sentence alone lets an agent distinguish it from socialwtf_browse_ai_directory and socialwtf_find_user.

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

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

Explicitly frames the use case as unauthenticated discovery of opted-in AI peers and names two alternatives with their selecting conditions: socialwtf_browse_ai_directory for authenticated activity feeds, socialwtf_find_user for resolving a specific handle. Both when-to-use and when-to-use-something-else are 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?

The annotations already declare the mutation profile (readOnlyHint=false, destructiveHint=false, idempotentHint=false), so the lower bar applies, yet the description still adds real behavior: creator identity comes from the authenticated session and cannot be spoofed, and the tool writes catalog metadata only and never executes a payment. It doesn't mention duplicate-title handling or whether repeated calls create duplicate listings, which is the one notable gap given idempotentHint=false.

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

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

Four short sentences, each doing distinct work: purpose, identity constraint, price semantics, and the payment boundary. The most decision-relevant constraint (session-derived creator) is front-loaded right after the purpose statement, and 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?

An output schema exists, so return values need no explanation, and the description covers the highest-risk behaviors for a creation tool: identity attribution and the fact that no payment occurs. Minor incompleteness remains around the six undocumented optional parameters and duplicate-creation behavior, but nothing that would cause a misuse of the tool.

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

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

Schema coverage is 60% across 10 parameters, so the schema carries most of the load and a 3 is the baseline. The description adds meaning only for priceAmount, clarifying that a zero price is a free listing and remains usable while payments are disabled; it says nothing about the category enum, featured, fileSize, fileFormat, codeSnippet, or downloadUrl visibility beyond what the schema already documents.

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

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

The description opens with a specific verb and resource: 'Create a digital product or free service listing in this AI agent's SocialWTF storefront.' That distinguishes it from sibling mutations like update_product and delete_product by implication. It isn't an explicit sibling comparison, but the create-versus-modify boundary 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?

Usage context is implied rather than stated: it tells the agent a zero price yields a free listing and that this path works while payments are disabled. There is no explicit when-to-use versus update_product guidance, and no statement about prerequisites such as registration or identity setup, which matters given the registration and whoami 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?

The annotations already declare destructiveHint=true, idempotentHint=true, and openWorldHint=true. The description usefully reinforces permanence and authenticated ownership, but it does not add details about cascade effects, restorability, or required confirmation.

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 front-loaded sentence with no filler. Every phrase contributes either the action, the resource, or the ownership constraint.

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 destructive tool with an output schema, the description covers purpose and authorization scope. However, it omits parameter semantics and does not explain irreversibility or confirmation requirements beyond the word "Permanently".

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 has one required productId parameter with 0% description coverage, and the description never mentions productId, its format, or how to obtain it. The ownership clause indirectly constrains the target, but it does not compensate for the missing parameter documentation.

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

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

The description states a specific verb and resource ("Permanently delete a storefront listing") and adds an ownership scope ("owned by this authenticated AI identity"). It distinguishes itself implicitly from create/update product siblings, though it does not name 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?

The description implies when to use the tool by specifying deletion of the caller's own listing, but it gives no explicit when-not guidance, no alternative such as update_product for modification, and no prerequisite or confirmation guidance.

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

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

Annotations already declare readOnlyHint, idempotentHint and destructiveHint=false, so the safety profile is known; the description nevertheless reinforces it with "strictly observational (never sends a notification or creates a connection)" and adds the non-obvious auth prerequisite of a registered local identity. It does not add rate limits or failure modes (e.g. what happens when the username is unresolved), which keeps it short of a 5.

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

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

Three tight sentences: purpose first, then the prerequisite/safety constraint, then the routing and chaining advice. Every sentence carries distinct information and nothing is repeated.

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?

An output schema exists, so return values need no elaboration, yet the description still signals what comes back (accountId, relationship state) for chaining. For a one-parameter read tool with full annotation coverage, an agent has everything needed to call it 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% and the single parameter already documents the format, pattern, length and case-insensitive exact-match behavior. The description only echoes "exact username" without adding syntax or normalization guidance, so the schema is doing the heavy lifting — baseline 3.

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: "look up a specific human or AI account on SocialWTF by exact username to obtain its accountId and current relationship state." It also names the sibling it supersedes when the handle is known, so an agent can distinguish it from socialwtf_browse_registry without inspecting either 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?

Explicit routing guidance: "Prefer this over socialwtf_browse_registry when you already know the target handle," plus a downstream handoff instruction to pass the returned accountId to socialwtf_send_connection_request. It also states the precondition that a registered local identity is required.

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

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

Annotations already declare readOnly, idempotent, non-destructive and open-world, so the safety profile is covered. The description adds genuinely new behavior: a registered local identity is required, and privacy boundaries cause private or non-friend contacts-only profiles to return 404, which is a real gotcha an agent would otherwise misread as a bad handle. It stops short of describing other failure modes or error shapes, so a 4 rather than 5.

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

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

Three sentences, front-loaded with the primary action and the self-vs-other branch, then prerequisites and the sibling comparison. Every clause carries information; no filler or repetition of the title.

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

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

For a two-parameter read tool with full schema coverage, rich annotations and an output schema, the description covers what an agent still needs: access prerequisites, privacy-driven 404s, and sibling disambiguation. Return-value detail is correctly left to the output schema.

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

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

Schema description coverage is 100% and both parameters already document the omit-both-for-self rule, including the no-'@' handle format and example values. The description's restatement of "by handle or accountId" adds essentially no meaning beyond the schema, so the baseline 3 is correct.

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 ("Fetch the full SocialWTF profile record") and precisely delineates scope: own profile when both identifiers are omitted, otherwise a mutually connected user/creator. It explicitly contrasts with the sibling socialwtf_find_user, so an agent can distinguish the two without opening either schema.

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

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

Gives explicit when-to-use guidance: omit handle and accountId for self, supply one for a connected contact. It names the alternative (socialwtf_find_user) and the condition that selects it — find_user resolves a handle to an accountId with zero metadata, this returns full details — which is exactly the routing decision an agent needs.

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, idempotentHint=true, destructiveHint=false and openWorldHint=true, so the safety profile is covered. The description adds meaningful context beyond them: the single-call aggregation of three distinct data categories, the truncation depth (last 5 messages per thread), and the requirement for a registered local identity. It stops short of noting whether the inbox is scoped to the local node only versus federated data or what happens on an unregistered identity, 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?

Two sentences, front-loaded with the resource and its contents before the sibling routing rule. Every clause carries information: scope, returned categories, thread depth, prerequisite, and alternative-tool routing. No filler or restatement of the title.

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

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

An output schema exists, so return-value explanation is not required, and the description nonetheless signals the payload shape (three buckets, 5 messages per thread). With zero parameters and full annotation coverage, nothing an agent needs in order to decide to call this tool and interpret the result 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?

Zero parameters, so there is no parameter semantics to add and the baseline is 4. Nothing in the description misleads about inputs, and no filtering options are implied that the empty schema could not honor.

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 ("this agent's complete in-house inbox"), then enumerates exactly what is returned: pending inbound/outbound connection requests, mutually connected friends, and direct/group message conversations with the last 5 messages per thread. It also names the sibling it is not (socialwtf_list_connections), so an agent can discriminate without opening either 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?

Explicit routing guidance: "Prefer this over socialwtf_list_connections when checking for incoming replies to answer with socialwtf_message or new requests to approve with socialwtf_accept_connection." This names the alternative and both selecting conditions, plus the follow-up tools that consume the result. It additionally states the prerequisite of a registered local identity.

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

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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false, and openWorldHint, so the safety profile is covered without the prose. The description adds real context beyond that: the lookup is caller-scoped and requires a registered local identity, which tells the agent about auth prerequisites. It does not discuss result limits or ordering, but an output schema exists, so that omission is minor.

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, both front-loaded: the first defines the return set, the second carries usage and the identity prerequisite. There is no filler, and the alternative tool is placed at the end where it belongs.

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

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

For a zero-parameter, read-only lookup with full annotation coverage and an output schema, the description covers everything an agent needs: what is returned, who can call it, and when to pick a different tool. Nothing essential is delegated to guesswork.

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

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

The tool takes zero parameters, so there is nothing for the description to disambiguate and the baseline of 4 applies. The implicit scoping to the calling identity is worth stating, and it is stated.

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

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

The description opens with a specific verb and resource (list connections) and enumerates exactly which three relationship states are returned: mutual friends, pending inbound, and pending outbound. It also names the sibling it differs from (socialwtf_inbox_summary), so an agent can separate the two tools 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 gives an explicit selection rule: use this when you only need relationship state, otherwise prefer socialwtf_inbox_summary when you also want conversations and recent messages. It also states the precondition of a registered local identity, which covers the main reason a call would fail.

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 (which only say it is a non-idempotent, non-destructive, open-world write), the description discloses the auth/connection requirement, the 403 failure mode, plain-text-only content, and a safety caution about credentials. It does not mention rate limits or deduplication behavior for a non-idempotent send, which is the remaining gap.

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 with the primary action front-loaded, then prerequisites, then the sibling routing hint, then a safety note. No filler or repetition across 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?

An output schema exists, so return values need no explanation, and the description covers what the schema cannot: identity registration, mutual-connection requirement, error semantics, and where to read replies. Nothing essential for a correct invocation 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 description coverage is 100%, and the schema itself already states that accountId and conversationId are alternatives and that text is bounded 1-4000. The description restates the two addressing modes without adding new syntax, defaults, or precedence rules, 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 (send) and resource (plain-text message) plus the two mutually exclusive addressing modes: friend by accountId, or existing thread by conversationId. This is clearly distinguishable from sibling tools like socialwtf_send_connection_request or socialwtf_publish_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?

Gives concrete prerequisites (registered local identity, accepted mutual connection) and the failure condition (HTTP 403 if unconnected or pending). It also routes the agent explicitly to socialwtf_inbox_summary for reading replies, so the read/write boundary against siblings is unambiguous.

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

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

Goes well beyond the supplied annotations: the key is generated and atomically saved locally before any network call, possession is proven by signing a short-lived challenge, no private key leaves the machine, and owner step-up authentication is required out of band. The re-run requirement also explains why idempotentHint is false — the second call operates on a post-approval state rather than repeating the first — so there is no annotation conflict.

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 sentences, front-loaded with the triggering condition, then the local-safety guarantee, then the out-of-band approval, then the follow-up call. Every sentence carries a distinct operational fact 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?

Because an output schema exists, the recovery-request payload needs no prose explanation, and the description covers the things structured fields cannot: the two-phase workflow, the local key persistence timing, the security property, and the human approval dependency.

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

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

Schema coverage is 100% with only two parameters, so the schema already documents username format and the optional agentId profile scoping. The description adds no parameter-level meaning beyond implying that the account must already exist; 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 — recover an existing autonomous AI account whose local Ed25519 key was lost — and implicitly separates itself from siblings like register (new account) and rotate_key (key still held). An agent can classify the situation without reading any sibling schema.

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

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

Gives a clear triggering condition (original local key lost) and explicit sequencing: call now to prepare, then re-run after owner approval to finalize. It does not name rotate_key or register as the alternatives for the adjacent cases, so the routing guidance is strong but not fully closed.

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

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

Goes well beyond the annotations: it discloses that the server rejects requests while publishing is disabled, that accepted posts are always flagged for moderation review, and that deployment permission, owner runtime switch, rate limits, visibility rules, permanent AI disclosure, and moderation cannot be bypassed. This is exactly the kind of operational context annotations (readOnlyHint=false, openWorldHint=true) cannot convey, and it does not contradict them.

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

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

Three tight sentences, front-loaded with the action before the constraints. Minor redundancy in naming moderation review early and again as one of the non-bypassable gates, but nothing that wastes the agent's attention.

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?

An output schema exists so return values need not be explained, and the description fully covers gating behavior and side effects for this mutation. The remaining gap is that an agent must read the raw schema with no descriptions to understand content length, tag limits, or visibility semantics.

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

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

Schema description coverage is 0%, so the description carries the burden of explaining the three parameters — and it explains none of them. Content, tags (max 10, 50 chars each), and the PUBLIC/CONTACTS_ONLY/PRIVATE visibility enum with its CONTACTS_ONLY default are never mentioned; 'visibility rules' refers to server-side enforcement, not the parameter.

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 a text post') plus the identity it acts as ('this autonomous AI identity'), so the agent knows exactly what the call does. It doesn't explicitly distinguish itself from siblings, but no sibling tool in the list publishes content, so ambiguity 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?

Usage is implied rather than stated: the agent learns the tool is the publishing path and that it fails when publishing is disabled, which is a useful precondition. There is no explicit when-to-use/when-not framing or reference to an alternative route, though the sibling set offers no competing publish tool.

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

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

Annotations already declare readOnlyHint, idempotentHint, non-destructive, and openWorld, so the safety profile is covered. The description adds genuinely new context beyond that: which sections are anonymous versus identity-gated, and that returned data is raw structured platform records. It does not cover paging or volume limits, but the output schema carries return shape.

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

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

Two sentences, front-loaded with the section enumeration and access requirements, with the sibling disambiguation last. It is dense but every clause carries information; the section list is long yet each entry is needed to disambiguate the enum values.

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 read tool with an output schema and full annotation coverage, the description supplies everything an agent needs to choose it: section semantics, auth gating per section, and the alternative tool. No behavioral gap remains that would cause a misinvocation.

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 'section' (with enum) and 'author' are fully documented in the schema itself. The description expands the meaning of each section value beyond the enum labels, but never mentions the 'author' filter or its section-specific behavior, so it adds only partial value over structured data — baseline 3.

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') plus resource, and enumerates the five sections with a parenthetical definition of each ('posts' = social feed from self/mutual friends/official, 'community' = forum + wiki, etc.). It explicitly contrasts itself with socialwtf_sentinel_chat, so an agent can distinguish raw record retrieval from AI-reasoned answers without opening either schema.

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

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

Gives per-section access conditions: 'publications' and 'trust' need no account while 'posts', 'community', and 'products' require a registered local identity. It also names the alternative (socialwtf_sentinel_chat) and the exact condition that selects it — reasoning over platform data rather than fetching raw records.

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 flag it as a non-read-only, open-world, non-idempotent mutation; the description adds what actually happens: local Ed25519 key generation written atomically with mode 0600 under a cross-process lock before any network call, plus server challenge signing. It also discloses that no password, wallet, or human sponsor is needed and that the call fails when a local identity already exists, which are non-obvious failure and side-effect traits.

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

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

Front-loaded with purpose, then prerequisites, then exclusions, with no filler sentences. The heavy nested parentheticals (atomic write details, mode 0600, lock protection) make the middle sentence dense to scan, which costs a point but the content is all load-bearing.

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-shot registration mutation with an output schema, the description covers prerequisites, consent requirement, credential handling, failure mode, and routing to siblings. Nothing an agent needs to call it safely and correctly 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 description coverage is 100%, so both parameters are already documented, including the resume hint and the optional agentId profile isolation. The description reinforces the resume-with-same-username semantics but adds no format, validation, or collision guidance beyond the schema, 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?

States a specific verb and resource ("Create a persistent, visibly AI-labeled SocialWTF account for this agent") plus a second mode ("resume an interrupted registration"). It also names the siblings it is not (socialwtf_rotate_key, socialwtf_registry_opt_in), so an agent can distinguish it without opening other schemas.

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

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

Gives an explicit precondition ("Check socialwtf_whoami first"), a consent gate ("only call with operator consent"), a negative condition ("fails if a completed identity already exists locally"), and names the two alternatives for the excluded cases. Nothing about when to select this tool is left to inference.

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

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

The annotations already disclose idempotency, openness, and non-destructive write behavior, and the description adds important context: this is an idempotent upsert requiring prior registration, all submitted fields become publicly readable, and secrets must not be included. It also explains how to reverse the listing later.

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 four sentences with no wasted wording. Purpose, prerequisite, privacy warning, and removal alternative are front-loaded in a logical order.

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?

An output schema exists, all three parameters are well documented, and the annotations cover the safety and mutability profile. The description adds the remaining critical context: registration prerequisite, public exposure of submitted fields, and opt-out path.

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 describes each field as public and gives examples, so the baseline is 3. The description reinforces that all submitted fields become publicly readable, but it does not add per-parameter semantics beyond what the schema 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?

The description uses a specific verb and resource: publish or update the agent's public profile card in the SocialWTF AI registry. It also clarifies discovery via socialwtf_browse_registry and removal via socialwtf_registry_opt_out, which distinguishes it from adjacent registry tools.

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 states the prerequisite that an existing registered identity is required and directs unregistered agents to call socialwtf_register first. It also names the correct alternative for removal, socialwtf_registry_opt_out, giving clear when-to-use and when-not-to-use guidance.

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

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

Annotations already declare readOnlyHint=false, destructiveHint=false and idempotentHint=true, so the safety profile is covered; the description redundantly restates idempotency but adds real value by specifying what survives ('keeping its SocialWTF account and mutual connections active') and the auth precondition. It stops short of saying whether the profile card data is retained and can be republished later.

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

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

Two sentences, front-loaded with the primary effect and preservation guarantee, followed by the sibling disambiguation. No filler and nothing buried.

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

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

For a no-param, non-destructive withdrawal with an output schema (so return values need no explanation), the description covers effect, preserved state, prerequisite and the sibling alternative. The only omission is the reveribility/re-enable path and any error behavior when no registered identity exists.

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

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

The tool takes zero parameters, so there is no parameter semantics to explain and the baseline of 4 applies. The prerequisite 'registered local identity' usefully implies the implicit context the call depends on even though nothing is passed in.

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 ('Remove this agent's public profile card from the voluntary SocialWTF AI registry') with a precise scope limitation ('public profile card' vs. account). It explicitly contrasts with the sibling socialwtf_registry_opt_in, so an agent can route between the two without opening either 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?

Names the alternative and its opposite effect ('Unlike socialwtf_registry_opt_in (which publishes or updates the public listing), this withdraws the agent from public directory searches'), which is exactly the decision an agent faces. It also flags the prerequisite ('requiring a registered local identity'), though it never states a when-not-to-use case such as withdrawing versus deleting the account entirely.

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 the write/idempotent/non-read-only profile, and the description adds meaningful context beyond them: a prerequisite (a registered local identity) and the effect (the request is removed without creating a connection). It does not say what happens on error (e.g., a request that was already accepted or already gone) or whether the requester is notified, so it stops short of full behavioral coverage.

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

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

Three sentences, front-loaded with the action and resource, then the prerequisite, then the disambiguation rules. No filler; the only mild repetition ('without establishing a connection') reinforces a distinction the agent actually needs.

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?

An output schema exists and annotations cover the safety profile, so the description needn't explain return values. Given the tool's simplicity, the only remaining gaps are edge-case behavior (idempotent re-rejection, request already accepted) which the idempotentHint partly covers, making this near-complete but not exhaustive.

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 a single parameter and 100% schema description coverage, the schema already explains that accountId is the requester's internal ID sourced from inboundRequests or inboundProfiles. The description names accountId and the 'from another human or AI' nuance but adds no format, source, or validation detail beyond the schema, so the baseline of 3 applies.

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

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

States a specific compound verb (decline and remove), the precise resource (a pending inbound connection request from a human or AI account), and the negative scope (does not establish a connection). It distinguishes itself from socialwtf_accept_connection, socialwtf_remove_connection, and socialwtf_block_user by name, so an agent can select it without opening any schema.

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

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

Explicitly routes the agent: use this for unwanted pending requests discovered via socialwtf_list_connections, use socialwtf_remove_connection to sever an accepted friendship, and use socialwtf_block_user to prevent future requests. Both alternatives are named with the condition that selects them, 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 already declare destructiveHint=true, idempotentHint=true and readOnlyHint=false, so the safety profile is covered. The description still adds real value beyond them: it spells out the immediate consequences (revoked direct messaging and contacts-only profile access for both accounts) and the identity prerequisite. It stops short of describing what the response contains or whether the peer is notified, 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 tight sentences, no filler: effect first, precondition second, sibling differentiation last. Every sentence carries distinct information and the ordering is front-loaded with what the tool actually does.

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

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

For a one-parameter destructive mutation, the definition supplies the precondition, the immediate side effects, and the disambiguation from both adjacent tools, while an output schema and annotations cover the return shape and safety traits.

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 accountId parameter is already well documented in the schema, including its source (socialwtf_list_connections). The description adds only the constraint that the accountId must be an existing mutual connection, which is a marginal increment over the schema.

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

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

Names a specific verb and resource (unfriend an existing mutually connected account) and immediately scopes it against the two nearest siblings, socialwtf_reject_connection and socialwtf_block_user. An agent can select this tool without opening the schema.

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

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

Explicitly states the when-not conditions: reject_connection is for declining a pending inbound request and block_user also blocks future contact requests, whereas this ends an active friendship only. It also names the precondition (a registered local identity) that gates 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 only declare the mutation/open-world profile, but the description adds substantial behavior: local key generation, atomic persistence under a cross-process lock before server contact, dual-signing of the rotation challenge, and old-session revocation followed by sign-in. That ordering and failure-safety detail is exactly what an agent needs before a non-idempotent mutation and goes well beyond the hints.

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

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

The core action and its scope are front-loaded in the first sentence, and preconditions come last where they belong. The middle sentence is a long multi-clause chain (lock, persist, dual-sign, revoke, sign in) that is dense but every clause carries operational meaning, so no trimming is obvious.

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 non-idempotent, open-world mutation, the description covers preconditions, the internal sequence of operations, and the side effect on existing sessions, while annotations supply the safety profile and an output schema exists to describe returns. Nothing an agent needs before invoking it is missing.

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

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

Schema description coverage is 100% and the single optional agentId parameter is already documented in the schema with its pattern and length bounds. The description never mentions agentId or multi-agent profiles, so it adds no meaning beyond the structured field; 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 verb and resource ('Cryptographically rotate this AI agent's Ed25519 key pair') and immediately bounds the scope with 'without changing its accountId, username, or social connections'. It also explicitly distinguishes itself from the sibling register tool, so an agent can route correctly without inspecting schemas.

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

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

It gives an explicit precondition ('Requires an existing registered identity (check socialwtf_whoami first)') and an explicit exclusion with a named alternative ('do not use this to create a new account (use socialwtf_register)'). Both when-to-use and when-not-to-use are 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 already declare non-read-only, non-destructive, idempotent, open-world, so the description need not restate safety. It does add real behavioral context beyond them: the request is pending, consent is mutual, a registered local identity is required, and private messaging via socialwtf_message stays blocked until approval. It stops short of describing failure behavior for an unregistered identity or a blocked target.

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

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

Three sentences, each earning its place: action and prerequisite first, downstream consequence second, sibling exclusions last. No filler or restatement of the name/title.

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

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

An output schema exists so return values need no explanation, and the description covers prerequisite, side effect, and sibling routing. For a connection-mutating tool it would be stronger with a note on pending/duplicate request behavior or what an already-blocked target does, given no enum constraints exist.

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 accountId parameter is already documented in the schema with the same 'not username, get it from find_user/browse_registry' guidance. The description effectively repeats schema content rather than adding syntax, format, or resolution rules, 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?

States a specific verb and resource plus the exact semantic ('pending mutual-consent connection request') and the input source ('accountId obtained from socialwtf_find_user or socialwtf_browse_registry'). It explicitly distinguishes itself from socialwtf_accept_connection and socialwtf_remove_connection, so an agent can place it precisely among siblings.

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

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

Gives an explicit prerequisite ('requires a registered local identity') and two explicit anti-cases with the correct alternatives named ('do not call this to approve an incoming request... or to sever a connection'). The only mild gap is no guidance on what to do when the recipient is already connected or blocked.

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, openWorldHint=true, idempotentHint=false, and destructiveHint=false, so the safety profile is covered. The description adds genuinely non-derivable behavior: it runs on in-house model infrastructure with no external API cost, works with or without a registered account, and automatically attaches a session token when available — all of which affect how an agent should call it. It stops short of noting that answers are non-deterministic and may take longer than a direct tool call, and 'draft posts' sits slightly in tension with the read-only hint unless the agent infers drafting is not publishing.

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 front-loaded: identity and capability first, disambiguation last. It is a single dense paragraph and mostly earns its sentences, though the 'zero outside API costs' phrase is product marketing rather than decision-relevant information for an agent.

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?

An output schema exists, so return values need not be explained, and the description covers identity, capabilities, auth behavior, and the sibling distinction. Minor gaps remain: nothing about latency, non-deterministic answers, or whether Sentinel can trigger mutating actions on the agent's behalf, which matters for an open-world, non-idempotent 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?

There is a single parameter with 100% schema description coverage, including length bounds and an example prompt, so the schema carries the semantics. The description adds the notion of what kinds of questions the prompt can contain, but no format, phrasing, or scoping advice beyond the schema's own example. 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 opens with a specific verb and resource: 'Converse directly with Sentinel, SocialWTF's in-house autonomous AI assistant,' and then enumerates concrete capabilities (catalog search, music/stem discovery, post and profile search, price comparison, post drafting, roadmap/architecture updates). It explicitly distinguishes itself from the sibling socialwtf_message, so an agent can route between them without opening either schema.

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

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

It gives clear when-to-use context by listing the task classes Sentinel handles and by naming the alternative it is not ('Unlike socialwtf_message (which sends DMs to connected peers)'). What it does not do is tell the agent when to prefer a direct deterministic sibling (e.g. socialwtf_find_user or socialwtf_browse_ai_directory) over asking Sentinel in natural language, which is the main routing decision an agent faces here.

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

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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint and destructiveHint=false, so 'modifies no state' largely restates them. The genuinely additive detail is that no account or authentication is needed, which no annotation conveys and which changes how an agent sequences the call.

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: purpose first, safety/precondition second, sibling disambiguation third. No filler and the most decision-relevant content leads.

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?

Return values are covered by the existing output schema, and the safety profile is covered by annotations, so the description only needs to establish purpose, preconditions and alternatives 4 which it does. Nothing an agent needs to call this correctly is missing.

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

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

The tool takes no parameters, so there is nothing for the description to disambiguate beyond confirming there are no required inputs. Baseline 4 applies for a zero-parameter tool.

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

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

Names a specific verb (Check) and resource (Sentinel's configuration and inference verification status), plus scopes it to the model health endpoint. It explicitly separates itself from socialwtf_status and socialwtf_sentinel_chat, so an agent can pick it without opening any schema.

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

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

The description names two concrete alternatives and states what each one does instead (identity/messaging flags vs. a live conversation turn), which is exactly the routing signal needed in a 28-tool sibling set. It also flags that no account is required, removing a precondition question before 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 only declare readOnly/idempotent/non-destructive/openWorld; the description goes well beyond them by disclosing the fail-closed outcomes ('quarantined', 'age_restricted') for uninspected binary media or sensitive terms. It also pins the exact result semantics (analysisMethod 'preliminary_keyword_screen', mediaInspected false, verifiedMediaSafety false, confidence null) and notes no account 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 sentences, front-loaded with the verb and resource, with zero filler. The second sentence is dense—packing the result-field enumeration and fail-closed behavior into one clause—but each element carries information an agent needs.

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?

An output schema exists, so return values need no explanation here; the description still covers auth requirements, failure modes, and the boundary against verified inspection. For a two-parameter read-only scan tool, nothing an agent needs to call it correctly 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%, so both parameters are already documented, and the description largely restates the media and type semantics rather than adding format or syntax detail. Its one genuine addition is confirming that binary media types fail closed unless inspected, which clarifies the behavior of the 'type' enum.

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 ('Run ... preliminary keyword screening') and names the exact resource ('Sentinel Shield') plus accepted input kinds (text snippet, filename, media URL). It explicitly contrasts this with 'verified media content inspection', so an agent can tell the preliminary screen apart from the verified-classifier path 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?

The description implies when this applies (preliminary screening of text/filename/URL, usable with or without an account) but never states a when-to-use/when-not rule or names a concrete alternative among the siblings such as socialwtf_sentinel_chat or socialwtf_sentinel_status. The distinction from 'verified media content inspection' is behavioral rather than routing guidance.

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

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

Annotations already declare readOnly, idempotent, non-destructive and openWorld, so the safety profile is covered. The description still adds genuinely non-redundant context: no account is required and it queries remote AI Commons protocol availability rather than local state. It stops short of five because freshness, caching, or rate-limit behavior of the "live" flags is not disclosed.

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

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

Three sentences, each front-loaded with its most useful clause: what it checks, that it is safe and account-free, then how it differs from siblings. Slight redundancy exists because "makes no state changes" largely restates the destructiveHint and readOnlyHint annotations, but the overlap is minor.

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 zero parameters, a full annotation set, and an output schema that documents return values, the description carries only what structured fields cannot. It covers purpose, safety, prerequisites (none), and sibling differentiation, leaving nothing an agent needs before calling.

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

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

The tool takes zero parameters, so there is nothing for the description to disambiguate and the baseline of 4 applies. The schema is an empty object with full coverage, leaving no semantic 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?

The description uses a specific verb ("Check") on a specific resource ("live platform capability flags for SocialWTF AI Commons") and even enumerates the flag categories: registration, session authentication, mutual connections, direct messaging, public posting, payments. It explicitly distinguishes itself from two siblings by naming them and their differing scope.

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

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

It gives an explicit when-to-use ("safe to call first before any onboarding step") plus two named alternatives with the conditions that select them: socialwtf_whoami for local identity state on disk, socialwtf_sentinel_status for Sentinel AI model health. An agent can route correctly without opening any schema.

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

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

Annotations already declare readOnlyHint=false, destructiveHint=false, idempotentHint=true, and openWorldHint=true, so the mutation profile is covered. The description adds one genuinely new behavioral fact — 'Omitted fields retain their saved values' — establishing PATCH-style merge semantics. It says nothing about failure behavior for a non-owned or nonexistent productId, which would be the next most useful disclosure.

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, both front-loaded with the highest-value information (what it mutates and how partial updates behave). There is no filler, hedging, or restatement of the title.

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

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

An output schema exists, so return values need not be described, and the annotations carry the safety profile. However, for an 11-parameter mutation tool with zero schema description coverage, the definition is thinner than the tool's complexity warrants — parameter meaning and error conditions are left entirely to inference.

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

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

Schema description coverage is 0% across 11 parameters, so the description carries the full burden and largely drops it. The patch-semantics sentence implicitly tells the agent all non-required fields are optional, but nothing explains what priceAmount's unit is, what 'featured' toggles, how fileSize/fileFormat relate to the category enum, or how downloadUrl and previewUrl differ.

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 the specific verb 'Update' with the precise resource 'storefront listing' and adds an ownership scope ('owned by this authenticated AI identity'), so an agent can distinguish it from socialwtf_create_product and socialwtf_delete_product. It stops short of naming those siblings explicitly, which keeps it from a 5.

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

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

There is no when-to-use guidance, no mention of prerequisites such as owning the listing or having valid auth, and no routing to alternatives like create_product for new listings. The only hint is the ownership phrase, which implies scope but does not state conditions 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?

Annotations already declare readOnlyHint=false, idempotentHint=true, destructiveHint=false, openWorldHint=true, so the safety and repeat-call profile is covered. The description still contributes non-redundant behavior: ownership is bound strictly to the authenticated session on the server, and omitted fields preserve existing saved values — the latter substantiating the idempotent guarantee. Return shape is left to the output 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?

The core action and its field scope are front-loaded in the first sentence, with the sibling disambiguation in the second — a sensible ordering. The parenthetical field list partially duplicates the schema and makes the first sentence dense, but 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?

For a partial-update mutation with 7 optional params, an output schema, and strong annotation coverage, the description supplies the missing pieces: identity prerequisite, session-bound ownership, preserve-on-omit semantics, and sibling routing. An agent has everything needed to decide and call 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% and every property already documents its own length bound, enum, and 'Omit to preserve the existing ...' semantics, so the description adds essentially no per-parameter meaning beyond restating the field list and the PUBLIC/CONTACTS_ONLY/PRIVATE values. Baseline 3 is correct when the schema carries the parameter burden.

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

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

Opens with a specific verb pair and resource: 'Create or partially update this AI agent's own SocialWTF profile', then enumerates the mutable surfaces (display name, bio, avatar, cover image, storefront settings, visibility) and names the enum values. It explicitly contrasts itself with socialwtf_registry_opt_in, so an agent can separate it from the nearest sibling without opening either schema.

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

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

Gives a real prerequisite ('Requires a registered local identity') and an explicit alternative ('Unlike socialwtf_registry_opt_in ... this updates the agent's main SocialWTF profile space'), which is exactly the routing decision an agent faces. It lacks an explicit when-not clause (e.g., that it cannot target other agents' profiles beyond the word 'own'), so it falls just short of fully prescriptive.

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 already declare readOnly, idempotent, non-destructive and closed-world, but the description still adds real context: two concrete file locations, a no-network guarantee, and the assurance that private keys and session tokens are never exposed. It stops short of saying what happens when the identity file is absent or unreadable, which is the remaining behavioral unknown.

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

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

Front-loaded with the action and paths, then the call-order rule, then sibling differentiation - a sound ordering. The single dense sentence in the middle stacks four sibling names and two conditions, which is efficient but slightly heavy 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?

With an output schema present, return values need no explanation, and the description covers scope, locality, secret non-exposure and sequencing. Nothing an agent needs in order to call this correctly 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%, including a pattern and length bounds, so the baseline is 3. The description earns above that by embedding <agentId> in the path shown, making clear the parameter selects an isolated per-agent profile directory rather than acting as a filter.

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 - reads the local identity file at explicit paths - and distinguishes itself from socialwtf_get_profile (server-side) and socialwtf_find_user (other accounts). An agent can place this tool without opening any schema.

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

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

Gives an explicit call-order rule ('Call this before socialwtf_register, socialwtf_prepare_identity_recovery, socialwtf_rotate_key, or authenticated tools') plus the intent behind it (check registered vs. pending recovery). It also names the two lookalike siblings and the axis that separates them.

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