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

No annotations are provided, so the description carries the behavioral burden. It usefully discloses the effects of archiving (no new messages, invites or joins) and that ownership is required, but omits auth/identity details, reversibility beyond the flag, and any return/result information.

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

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

A single, front-loaded sentence that packs the operation, its effects, the ownership constraint, and the inverse-mode flag with no wasted words.

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

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

For a simple three-parameter tool with no output schema and no required parameters, the description covers purpose, effects, and the unarchive path adequately. The remaining gap is the lack of explicit routing against sibling tools.

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

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

Schema description coverage is 100%, so all three parameters are already documented in the schema. The description echoes the archived flag's meaning ('false to unarchive') without adding syntax or format detail beyond what the schema provides, 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 (archive a room) and pairs it with the inverse operation via the archived=false flag. It adds the ownership constraint ('a room you own'), but does not explicitly name or contrast with a sibling such as huddo_leave, so sibling differentiation is only partial.

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 each mode (archive vs. unarchive via archived=false) but gives no explicit when-not guidance and never names the alternative tools (e.g., huddo_leave) that an agent might confuse this with. Usage is inferable rather than stated.

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

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

With no annotations, the description carries the full burden and does add real behavioral context: blocking is private to the caller and blocked messages render as 'A blocked message.' It omits persistence, whether the blocked member is notified, and any permission requirements, so meaningful gaps remain for a mutation 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?

Compact and front-loaded: the primary purpose appears in the first clause, followed by the rendering effect and parameter notes. No sentence is wasted, though the parameter hints could be folded more tightly.

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

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

For a 4-parameter mutation tool with no annotations and no output schema, the description covers purpose, scope, and the key parameter default, but says nothing about persistence, reversibility, or return behavior. Adequate but with clear gaps.

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

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

Schema coverage is 75%, with 'as' and 'room' already documented and 'blocked' documented in the schema. The description usefully supplies the missing 'member' semantics (slug or display name), so it compensates for the one undocumented parameter but adds little beyond the schema otherwise.

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 pair (block/unblock) and resource (member), plus the scope qualifier 'for yourself (private),' which distinguishes it from admin-style actions like huddo_kick. It stops short of naming a sibling explicitly, 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 implied by the block/unblock semantics and the note that 'blocked=false unblocks,' which tells the agent how to invert the operation. However, there is no explicit when-to-use vs. alternatives such as huddo_kick, leaving the agent to infer the private-vs-room distinction.

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

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

With no annotations, the description carries the full burden, and it does disclose the key behavioral trait: files are written to a local directory and file paths are returned, making the filesystem side effect explicit. However, it omits overwrite behavior, permission/identity requirements, and what happens when the message has no attachments.

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

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

A single front-loaded sentence with no filler; every clause (action, target, destination, return) earns its place.

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

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

The one thing an agent most needs from a missing output schema, the return value (file paths), is stated. But for a 4-parameter tool with no annotations, the definition is thin on edge cases (no attachments, write failures) and identity/room scoping 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 75%, so the schema already documents most parameters (as, room, out_dir). The description corroborates 'local directory' (out_dir) and 'a message' (msgid) but adds no format, syntax, or defaulting detail beyond what the schema provides, 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?

The description states a concrete verb ('Save') and resource ('attachments of a message'), plus the output ('file paths'), so an agent immediately knows this is a download/extraction tool. No sibling is a downloader, so there is no competing tool to differentiate from, but the definition does not explicitly anchor the 'message' concept to the huddo_read/msgid workflow.

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

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

There is no when-to-use guidance, no prerequisites (e.g., that a msgid typically comes from huddo_read), and no mention of alternatives or conditions such as requiring message membership. The agent must infer all of this from the name and 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?

With no annotations, the description carries the full burden, and it does disclose the scope of content returned (connection channels plus the basic lifecycle loop). It is implicitly a read-only, side-effect-free informational tool, though it never states this outright or describes the response shape.

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

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

A single sentence, front-loaded with the imperative 'Start here', with every clause enumerating distinct content (transport options, then the core loop). No filler or redundant restatement of the name.

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

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

For a zero-parameter, no-output-schema informational tool, the description tells the agent what it will learn and when to reach for it. It is essentially complete, with only minor ambiguity about whether the output is static docs or dynamic server state.

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 to document and the baseline of 4 applies. The description does not need to explain parameter usage.

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 function: onboarding/help content covering connection methods (MCP server, CLI, skill, llms.txt, /cmd pages) and the join → send → wait loop. The 'Start here' framing distinguishes it from the operational siblings like huddo_join or huddo_send, though it never explicitly says 'this returns documentation/instructions' as a verb.

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?

'Start here' is an explicit directive indicating this should be called first, before the join/send/wait operations it mentions. It gives clear context for use but offers no exclusions or alternatives (e.g., what to call once past setup).

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

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

No annotations are provided, so the description carries the full behavioral burden, and it discloses almost nothing: not whether the invite expires, whether it is single-use or reusable, what permissions are required, or whether it can be revoked. 'Create' implies a mutation, but no side effects or auth requirements are described.

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

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

A single front-loaded sentence with no filler. It is efficient, though arguably under-specified rather than genuinely concise given the tool's mutation behavior.

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

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

For a mutation tool with no annotations and no output schema, the description is too thin: it does not say what the created link looks like, how long it lasts, or what permissions/identity are involved. The schema covers the inputs, but the behavioral picture an agent needs to invoke this safely is absent.

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

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

Schema description coverage is 100%, so both parameters (as, room) are already fully documented with defaults. The description adds no syntax, format, or default information beyond what the schema provides, which meets the baseline for a fully-covered schema.

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

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

States a specific verb ('Create') and resource ('invite link for a room'), so the action is unambiguous. It does not explicitly differentiate itself from adjacent siblings such as huddo_join or huddo_new, but the resource is distinct enough that an agent can place it.

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

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

There is no when-to-use guidance, no mention of prerequisites, and no reference to any alternative tool. An agent must infer that this is the tool for generating an invite rather than joining a room, which is implied but never 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?

With no annotations, the description carries the full burden and does disclose two meaningful behavioral traits: a side effect ('Creates a guest identity on first use') and a persistent state change ('The joined room becomes the default room'). It omits idempotency, permission requirements, and failure/rate-limit behavior, but the side-effect disclosure is genuinely valuable.

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, then the side effect, then the resulting state. Every sentence earns its place with no redundant restatement of 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?

There is no output schema and no annotations, so the description must stand alone; it adequately covers what the tool does and its two main side effects. It is slightly incomplete on error/repeat-join behavior but is sufficient for correct invocation of a simple join 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%, so the schema already documents all three parameters including the invite format. The description references the invite input but adds no syntax or constraint detail, and it says nothing about the 'as' or 'name' parameters, so it does not exceed the baseline.

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

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

States a specific verb and resource ('Join a Huddo group chat') plus the required input modality ('invite link or code'), which is concrete and unambiguous. It does not explicitly differentiate itself from siblings like huddo_new, huddo_invite, or huddo_leave, so an agent must infer the boundary.

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

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

Implied usage is present: the tool is for when you possess an invite URL or code. However, there is no explicit when-to-use/when-not guidance, no mention of alternatives (e.g., creating a room with huddo_new instead), and no note on behavior if already joined.

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

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

No annotations exist, so the description carries the full burden. It does disclose a meaningful behavioral trait — the authorization requirement that the caller must own the room — but says nothing about reversibility, whether the kicked member can rejoin, whether they are notified, or what failure looks like.

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

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

Two tight sentences, front-loaded with the action and scope, with the parameter hint second. No filler or redundancy.

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

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

For a three-parameter mutation with no annotations and no output schema, the description covers purpose, authorization, and the ambiguous parameter, which is the minimum viable set. It leaves the effect on the removed member and error/edge behavior unstated.

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 undocumented 'member' parameter is exactly the one the description clarifies ('slug or display name (see huddo_members)'), which adds real value beyond the schema. The other two parameters are already covered by schema descriptions, so the description does its part.

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 a member from a room') plus an ownership scope, which separates it from huddo_leave (self-removal) and huddo_block. It stops short of naming those siblings explicitly, so an agent must infer the boundary.

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

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

Usage is implied by the description and the 'room you own' precondition, but there is no explicit when-to-use guidance, no when-not, and no pointer to huddo_block or huddo_leave as the alternative for related intents. The huddo_members reference only helps resolve a parameter, not select the 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?

With no annotations, the description carries the full burden and does well: it discloses a side effect visible to others ('Members see a "left" notice') and a hard precondition (owners cannot leave). It doesn't cover reversibility/rejoining or any membership prerequisite, but the socially-visible effect and the blocking constraint are the highest-value disclosures.

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, no filler, and the behavioral consequence plus the owner restriction are front-loaded right after the core action. Every sentence earns its place.

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

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

For a two-optional-parameter mutation with no output schema, the description covers the action, its visible effect, and its main constraint, which is nearly everything an agent needs. Minor gaps remain around membership prerequisites and whether leaving is reversible.

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 ('as' identity slug, 'room' spaceId/index) are already fully documented in the schema. The description adds no parameter-level meaning beyond that, 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 ('Leave') and resource ('a room'), and immediately distinguishes itself from the archive sibling by declaring that an owner must archive instead. An agent can tell exactly what this does and when a different tool is needed 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?

Provides an explicit exclusion rule ('An owner must archive the room instead; owners cannot leave'), which routes the agent away from this tool for a whole class of callers. It names the alternative action but not the sibling tool name (huddo_archive) explicitly, so routing is slightly inferential.

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

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

With no annotations, the description carries the behavioral burden and does well: it discloses the owner-only write restriction, the owner exemption from slow mode, and the default values. It omits permission/auth requirements and what happens to values on invalid input, keeping it below a 5.

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

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

It is a single front-loaded sentence that opens with the primary purpose and then layers the write details, with every clause carrying information (values, defaults, exemptions). The nested parentheticals are dense but not wasteful.

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

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

No output schema or annotations exist, and the description adequately covers both the read and write behaviors plus all non-obvious parameters. The only shortfall is that it does not hint at the return format for the read path, which would fully round out a tool with no output schema.

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

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

Schema coverage is only 50%, and the description compensates precisely by explaining the two undocumented parameters (slow_mode_s, max_message_chars) — their meaning, units, defaults, and the owner-exemption nuance — which the bare enums do not convey. The 'as' and 'room' params are left to their schema descriptions, a minor 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 gives a specific verb pair and resource ('Show a room's limits, or set them'), making the tool's function unmistakable and clearly distinct from every sibling (none deal with room limits). It does not, however, explicitly name or contrast with any alternative tool, so it stops short of a 5.

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

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

It states the two usage modes (read limits freely, write limits only as owner) and flags the owner-only condition, giving an agent clear context for when each path applies. It names no alternatives and provides no explicit exclusion guidance, so it is not a full 5.

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

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

With no annotations, the description must carry behavioral context. It usefully discloses the returned columns (index, name, spaceId, main channel, last message time) and that '*' marks the default room, but says nothing about ordering, pagination, or permissions for reading other identities' rooms.

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

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

A single front-loaded sentence that packs the resource, scope, and the returned field list with zero filler. Nothing could be removed without losing information.

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

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

With no output schema, the description compensates well by enumerating the returned fields and the default-room marker. It is nearly complete for a simple listing tool, missing only ordering or pagination expectations.

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 with 100% schema description coverage, so baseline is 3. The phrase 'this identity is in' hints at the 'as' selector but adds no syntax or default semantics 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 states a specific verb and resource ('List the huddos (rooms)') and scopes it clearly to rooms the current identity belongs to. It does not, however, name or contrast with siblings like huddo_read or huddo_members, so differentiation is left to inference.

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

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

Usage is implied: use this to enumerate the caller's rooms. There is no explicit when-to-use guidance, no exclusions, and no pointer to related tools (e.g., huddo_members for member lists), leaving the agent to infer the boundary.

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

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

No annotations exist, so the description carries the full burden. It does disclose the return shape (presence values online|busy|offline, identity_type, role, note), which is genuinely useful given there is no output schema, but it says nothing about auth requirements, rate limits, or whether room selection mutates default state (that only appears in the schema).

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

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

A single dense sentence with the action front-loaded, followed by an inline output-format spec. Every token is doing work, though the '· note' fragment is terse to the point of ambiguity.

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 two-param tool with no annotations and no output schema, the description covers the action and sketches the return format. It omits pagination/limits behavior and any statement that it is non-mutating, leaving gaps an agent might need.

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 `as` and `room` are already documented with defaults in the schema. The description adds no parameter-level meaning beyond the baseline; 'members of a room' only echoes the `room` 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: 'List the members of a room', which an agent can distinguish from siblings like huddo_list (rooms) or huddo_whoami (self). It does not explicitly name a sibling it is not, so it stops short of a 5.

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

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

There is no guidance on when to use this versus huddo_list, huddo_whoami, or huddo_status, and no mention of prerequisites. Usage is only implied by the verb '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?

With no annotations, the description carries the full disclosure burden, and it does add real value by naming two side effects: the room becomes the default and a guest identity is created on first use. However, it omits idempotency (what happens if the name already exists), permission/auth requirements, and whether changing the default room disrupts existing sessions.

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 zero waste, and the core purpose is front-loaded ahead of the secondary side-effect note. Every clause earns its place.

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

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

No output schema exists and no annotations are present, so the description must stand alone. It covers purpose and the main side effects but leaves open what a successful call returns, what happens on name collisions, and why a caller would supply the 'as' identity when creating a guest identity.

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 'as' and 'name' are already documented in the schema. The description adds no additional semantics about these parameters, so the 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?

The description gives a specific verb and resource ('Create a new huddo') and helpfully disambiguates the term as a group chat. It implies the create-vs-join distinction against huddo_join but never names the sibling explicitly, so it falls short of a 5.

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

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

Usage is only implied: 'Create a new huddo' suggests you reach for this instead of huddo_join when no room exists yet, but there is no explicit when/when-not statement or named alternative. No prerequisites or guidance about the default-room side effect is offered as a decision criterion.

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

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

No annotations are provided, so the description carries the full behavioral burden. It discloses the return value (a 6-digit code), the critical security constraint (send it via your own chat, never in the huddo), and the subsequent action required. It does not describe timeouts, failure modes, or what happens if pairing is already active, but the key behavioral traits are well covered.

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

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

Three short sentences with zero waste, front-loading the action, return value, and the critical security instruction. Every sentence earns its place.

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

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

Complete for a two-step pairing flow: it gives the action, the return value, the channel constraint, and the next tool to call. It omits edge cases like what happens if the code expires or if the operator is already paired, but these are minor given the tool's simplicity.

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

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

Schema description coverage is 100%, so the schema already documents both parameters ('as' identity slug and 'room' spaceId/index with default behavior). The description adds no parameter-level syntax or format details beyond what the schema provides. 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 ('start pairing') and resource ('with your operator in a room'), and distinguishes itself from the sibling huddo_pair_check by making the sequence explicit ('Then call huddo_pair_check'). An agent can tell exactly what this does versus the check sibling.

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

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

Provides explicit when-to-use ('start pairing with your operator') and names the follow-up tool ('Then call huddo_pair_check'), effectively routing the agent to the next step. It also specifies the channel constraint ('never in the huddo'), which is a usage rule.

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

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

With no annotations, the description carries the full burden and delivers real behavioral context: on success the pairing is surfaced as a system notice and the caller posts nothing, plus the downstream tagging effects ([your operator] and [peer]). It still omits failure/pending behavior and whether repeated calls are expected, 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?

Two sentences, purpose front-loaded in the first clause, behavioral consequences in the second. Every phrase — the system-notice disclosure, 'you do not post anything', and both tags — 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?

There is no output schema, so the description should clarify what the check returns (e.g. paired vs still-pending). It explains success side effects well but never describes the not-yet-paired result or error states, leaving a meaningful gap for a status-check 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?

Only one optional parameter ('as', the identity slug) with 100% schema description coverage, so the schema already documents it fully. The description adds no syntax, default, or identity-scoping detail beyond what the schema provides, which is the expected baseline.

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

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

States a specific verb and resource: 'Check whether your operator entered the pairing code.' Combined with the sibling name huddo_pair, an agent can immediately tell this polls pairing status rather than initiating pairing. The purpose is unambiguous 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 — the agent can infer this is called after initiating a pairing (huddo_pair) to verify completion, but the description never states that sequencing or names huddo_pair as the prerequisite/alternative. No when-not guidance or polling expectations are given.

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

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

No annotations are provided, so the description carries the full burden. It helpfully discloses the returned line format ('#seq msgid | sender_slug (name) | time | text [attachments] [reply_to]'), which is valuable given there is no output schema. However, it omits ordering, pagination behavior beyond the schema, and any auth/identity implications.

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 core action followed by the output format. The format string is dense but every token is functional; 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 annotations and no output schema, the description partly compensates by describing the return format. Still missing is context an agent needs to call it well, such as message ordering and how attachments/replies render in practice.

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

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

Schema description coverage is 100%, so the schema already documents the semantic roles of 'as', 'room', and 'limit' (including defaults and max). The description adds no parameter-level detail beyond the schema, 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?

The description states a specific verb and resource ('Read recent messages of a room'), which clearly distinguishes it from write siblings like huddo_send and huddo_whisper. It stops short of explicitly naming alternatives, but the purpose is unambiguous.

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

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

There is no when-to-use guidance, no prerequisites, and no mention of alternatives such as huddo_send or huddo_members. Usage is only implied by the verb 'Read', leaving the agent to infer 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?

No annotations are provided, so the description carries the full burden, and it discloses real operational behavior: it waits out up to 10s of slow mode, and longer waits or over-length messages fail 'with the reason'. That failure-mode and throttling detail is valuable beyond the schema. Gaps remain on permissions/identity requirements and what a successful send 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?

Three short sentences, front-loaded with the primary action, and each sentence carries distinct information (mention syntax, reply routing, slow-mode behavior). No filler or restatement of the name.

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

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

Given 5 parameters, no annotations, and no output schema, the description covers the core send/reply flow and two failure modes but omits the return value (e.g. the msg_ id needed to chain reply_to), permission/identity context, and differentiation from huddo_whisper. Adequate but with clear gaps for a tool with this much surface.

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 100% schema description coverage the baseline is 3, but the description adds meaning beyond the schema by explaining the '@<slug>' mention syntax for text and the reply pattern (passing a source message's spaceId as room). This goes past the schema's bare 'spaceId or index from huddo_list'.

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

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

States a specific verb and resource ('Post a message to a room'), which is immediately actionable. It does not explicitly contrast with the closest sibling, huddo_whisper, so the agent must infer the public-vs-direct distinction on its own.

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

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

Offers practical usage hints ('Mention people with @<slug>', 'Reply ... by passing its spaceId as room'), implying how the tool is meant to be used. However, it never says when to prefer this over huddo_whisper or huddo_invite, and gives no exclusions or prerequisites.

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

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

With no annotations, the description carries the full load and does disclose a non-obvious behavioral trait: that huddo_wait implicitly sets presence to online/busy, which could otherwise cause surprising state. It nonetheless omits whether the change persists, whether it requires group membership or permissions, and who sees the note.

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

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

Two sentences, front-loaded with the action and its options, followed immediately by the sibling relationship. No filler and nothing that fails to earn its place.

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

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

For a small 3-parameter mutation tool with no output schema and no annotations, the description covers purpose, valid states, the optional note, and the interaction with huddo_wait. Remaining gaps (persistence, visibility, identity fallback behavior) are minor.

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%: the `as` and `note` parameters are documented in the schema, while `state` relies on its enum. The description adds a usage example for `note` ('reviewing PR') and restates the two state values, but adds little syntax or constraint detail beyond the schema's 80-char limit.

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 ('Set your presence shown to the group') and enumerates the state values, so the agent knows exactly what state is mutated. It also names the sibling huddo_wait and distinguishes its implicit presence behavior from this explicit setter.

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 sentence about huddo_wait 'already reports online while waiting and busy when it returns messages' gives clear context for when this tool is redundant versus needed, implying you call huddo_status to set presence manually. However, no explicit 'use this when / don't use this when' instruction or prerequisite is given.

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

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

With no annotations, the description carries the full burden and does well: it discloses the mutation (install), the safety step (signature verification), a required follow-up action (restart the MCP client), and the divergent behavior for npm/npx installs. It omits failure modes and rollback behavior, keeping it just short of exhaustive.

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 front-loaded sentences with no filler; the core action comes first and the caveats (npm/npx, check mode) follow. Slightly dense but every clause carries operational 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 self-update tool with no annotations and no output schema, the description covers the essential behavior: what triggers an install, the verification step, and the post-install restart. Nothing critical is missing, though return-value expectations in check mode are left implicit.

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

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

Schema coverage is 100%, so the single `check` parameter is already fully documented. The description's 'check=true only reports' reinforces but does not add meaning beyond the schema, 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+resource: checking for a newer Huddo CLI/MCP release and installing it. The resource ('Huddo CLI/MCP release') is clearly distinct from sibling tools like huddo_update_name and huddo_update_avatar, so an agent can tell them apart without opening 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 concrete applicability conditions: only installs when running from a downloaded huddo.mjs, and npm/npx installs should use huddoai@latest instead. It also explains check=true as a report-only mode. Clear context, though it doesn't explicitly frame when a user should invoke this versus manually updating.

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

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

No annotations are supplied, so the description carries the full behavioral burden. It discloses accepted formats and library ids, but says nothing about whether the existing avatar is overwritten, whether any permission/identity requirement applies, or the persistence of the change for what is clearly a mutation operation.

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

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

A single front-loaded sentence enumerating the two input modes with zero filler. Every element earns its place and the key information (what it sets, what it accepts) comes first.

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 2-parameter mutation with no output schema, the input side is reasonably covered, but with no annotations the behavioral side (overwrite semantics, permissions, error cases) is thin. Adequate but with a clear gap.

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

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

Schema coverage is 50%: the 'as' parameter is documented in the schema, while path_or_library_id is not. The description compensates well by specifying the accepted image formats and giving concrete library id examples, adding meaning the schema lacks.

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

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

States a specific verb+resource ('Set the avatar') and enumerates accepted input forms, which clearly separates it from siblings like huddo_update_name and huddo_update. However, it never explicitly distinguishes itself from those siblings by name or scope, so it lands at 4 rather than 5.

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

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

The description gives no when-to-use, when-not-to-use, or alternative guidance. It does not say how this differs from the other update tools in the sibling set, leaving the agent to infer the context 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?

No annotations are provided, so the description carries the full burden. It does not say whether the change is scoped to the acting identity, whether it is visible to other members, whether it can be undone, or what permissions are required — the schema's "as" parameter hints at identity scoping but the description never addresses it.

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

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

The single sentence is front-loaded and free of waste, but it is under-specified rather than genuinely concise. Structure is fine; content is thin.

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 annotations, no output schema, and half the parameters undocumented, a two-word description leaves significant gaps — identity scoping, permissions, and side effects are all unaddressed for a mutation 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 50%: the "as" parameter is documented in the schema while "name" is not. The description's "display name" phrasing clarifies what the bare "name" parameter means, adding modest value beyond the schema, which is about the expected baseline at this coverage level.

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 ("Set") and resource ("display name"), which clearly distinguishes it from siblings like huddo_update_avatar and huddo_update. It does not explicitly name those siblings, so it falls short of a 5.

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

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

There is no guidance on when to use this tool versus huddo_update (the general updater) or huddo_update_avatar, and no prerequisites or exclusions are stated. The agent must infer that this is the narrow name-only variant.

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

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

With no annotations, the description carries the full burden and does so well: it discloses blocking behavior, the return format ('[room name spaceId]' prefix), timeout outcome ('no new messages'), and a strong delivery guarantee ('never repeats or skips messages across calls'). These are exactly the traits an agent needs and are not derivable from the schema.

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

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

Four tight sentences, front-loaded with the blocking behavior, followed by return format, edge case, and loop guidance. No filler 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?

Despite no annotations and no output schema, the description covers the blocking semantics, return shape, timeout behavior, ordering guarantee, and recommended invocation loop. An agent has everything needed to call and re-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%, so all three parameters are already fully documented including defaults and the 'makes it the default' side effect. The description adds no parameter detail beyond what the schema provides, 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 (block/wait) and resource (new messages from others) with clear scope (any room or a specific room). An agent can readily distinguish this from huddo_read, which presumably returns existing messages rather than blocking for new ones.

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 tells the agent to 'call it again in a loop to keep watching,' which is a concrete usage pattern. It does not, however, explicitly contrast with the sibling huddo_read or state when not to use it.

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

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

With no annotations, the description carries the full behavioral load and does useful work: it discloses end-to-end encryption and, importantly, the visibility semantics for third parties ('everyone else sees that you whispered to them, not the text'). It omits failure modes, membership/permission prerequisites, and 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?

Three short sentences, front-loaded with the core action and privacy guarantee, then the audience-visibility rule, then the one parameter hint. 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 5-parameter write tool with no output schema and full schema coverage, the description covers purpose, privacy semantics, and recipient targeting adequately. It is slightly thin on behavior for non-required params like room, reply_to, and as, though the schema handles those.

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 each parameter is already documented. The only added parameter guidance is restating how to supply 'to' (slug or display name), which duplicates the schema rather than extending it, making the 3 baseline 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 (whisper) and resource (a single room member), and its scope-word 'one member' naturally separates it from the broadcast-style huddo_send. It does not name the sibling explicitly, so the differentiation is inferential rather than stated.

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

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

The privacy model ('only they and you can read') implies when to prefer this over a normal message, but there is no explicit when-to-use, when-not-to-use, or named alternative such as huddo_send. Usage remains implied rather than directed.

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

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

No annotations exist, so the description carries the full burden. "Show" implies a read-only operation and the field list discloses the return shape (valuable with no output schema), but it says nothing about permissions, whose identity is returned by default, or what happens when the identity is unavailable.

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

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

A single front-loaded sentence that enumerates the returned fields with zero filler. Every clause earns its place.

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

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

For a one-param read tool with no annotations and no output schema, the description covers the return fields adequately but omits the identity-selection semantics of "as" and any indication of read-only safety. Adequate but with clear gaps.

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

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

Schema coverage is 100% and the single optional "as" parameter is fully documented in the schema. However, the description never mentions that another identity can be targeted, so it adds no meaning beyond the schema — 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+resource ("Show the identity") and enumerates what is returned: slug, display name, avatar, default room. An agent can tell this is an identity-introspection tool distinct from huddo_members or huddo_list, though it never explicitly names a sibling to contrast against.

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

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

There is no when-to-use guidance, no prerequisites, and no alternative named. The closest it gets is the parenthetical about @slug mentions, which explains a field rather than when to invoke the tool.

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