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 for a mutation tool. It does not state that it requires the ADD_REACTIONS permission, what happens if the reaction already exists (idempotency), whether it adds to or replaces existing reactions, or any rate-limit behavior.

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

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

A single front-loaded sentence with zero wasted words. It is appropriately sized for the action, though it is so terse that it omits information an agent would need for correct invocation.

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

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

With no annotations, no output schema, and a mutation that succeeds or fails based on permissions and emoji validity, the description is too thin. It should at least note the permission requirement and behavior when the emoji or message is invalid.

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 channelId, messageId, and emoji (including the custom-emoji format). The description adds no parameter 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 ("Add") and resource ("emoji reaction to a message"), which is unambiguous against siblings. However, it does not explicitly distinguish itself from remove_reaction or clear_reactions, which are the nearest alternatives in the sibling 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?

There is no guidance on when to use this tool versus remove_reaction, clear_reactions, or send_message. No preconditions, no exclusions, and no indication of context (e.g., typical reaction workflows) are provided.

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, and it discloses almost nothing: it does not mention required permissions (typically Manage Roles), whether the operation is idempotent, whether it emits an audit-log entry (despite a reason parameter existing), or what happens on failure with an invalid role/user.

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

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

A single short sentence with the action front-loaded and zero filler. It is efficient, though its brevity borders on under-specification rather than conciseness.

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

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

For a state-mutating permission tool with no annotations and no output schema, the description should cover permission requirements, idempotency/side effects, and failure behavior. None of that is present, so the definition is materially incomplete despite the schema documenting the parameters.

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

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

Schema description coverage is 100% – all four parameters (userId, roleId, reason, guildId) are documented in the schema itself. The description adds no format, constraint, or default-resolution detail (e.g., how guildId defaults to DISCORD_GUILD_ID), so the baseline 3 applies.

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

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

States a specific verb (Assign) and resource (role to user in the server), which is clear enough to act on. However, it does not differentiate from the closely named sibling remove_role or mention the nuance of role assignment vs. role editing (edit_role), leaving that distinction to the name alone.

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

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

There is no when-to-use guidance, no prerequisite conditions (e.g., bot permissions), and no pointer to alternatives such as remove_role for the inverse operation. The agent must infer usage entirely from the name.

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

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

With no annotations, the description carries the full behavioral burden. It usefully discloses the message-purge window (0–604800s, capped at 7 days), but omits key traits for a destructive moderation action: required permissions, that the ban persists until unban_member is called, and error/edge behavior. Substantial gaps remain.

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; the action precedes the optional modifier. The parenthetical '0 to 604800 seconds = 7 days' duplicates schema content but is brief, so it is only a minor 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 no-annotation, no-output-schema moderation mutation, the description covers the core action and the purge option but leaves permissions, reversibility, and failure modes unstated. Adequate but with clear gaps given the tool's destructive nature.

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 userId, reason, guildId, and deleteMessageSeconds thoroughly. The description merely restates the deleteMessageSeconds range that the schema already encodes, adding no new semantics. 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+resource ('Ban a user from the server') that is clearly distinguishable from siblings like kick_member, unban_member, and timeout_member. The optional message-purge capability is also called out. However, it never explicitly contrasts itself with the adjacent moderation tools, 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?

The description explains what the tool does but gives no when-to-use guidance or routing to alternatives such as kick_member or timeout_member for less severe moderation. The purge-window mention is capability detail rather than usage guidance. An agent gets no help deciding ban vs. the other member-moderation 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?

No annotations, so the description carries the full burden. It usefully discloses the 14-day age limit (not present in the schema) and the 100-message cap, which are real behavioral constraints, but it omits permission requirements (Manage Messages), irreversibility, and partial-failure behavior.

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

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

A single front-loaded sentence with the core action first and the two hard constraints parenthesized. No waste.

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

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

For a destructive, annotation-free mutation tool with no output schema, the definition covers the practical constraints but leaves out permissions, irreversibility, and what happens when messages exceed 14 days. Adequate but with clear gaps.

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

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

Schema description coverage is 100%, so all three params are already documented. The description restates the max-100 constraint already in the schema and adds no syntax or format detail for 'reason' or 'channelId'. 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 ('Bulk delete (purge) multiple recent messages in a channel') and the 'bulk/multiple' scope implicitly distinguishes it from the singular delete_message sibling. No sibling is named explicitly, so it stops short of full differentiation.

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

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

The constraints (max 100, <14 days old) imply when it is applicable, but there is no explicit when-to-use/how-it-differs-from-delete_message guidance. 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?

No annotations are provided, so the description carries the full behavioral burden. It hints at bulk/destructive scope with 'all reactions', but says nothing about whether the operation is irreversible, what permission (e.g. Manage Messages) it requires, or how it behaves on a message with no reactions.

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

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

A single short sentence with no wasted words, and the action and scope are front-loaded. It is terse to the point of omitting behavioral context, but structurally sound.

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

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

For a destructive bulk mutation with no annotations and no output schema, the description should disclose permissions, irreversibility, and edge-case behavior. None of that is present, leaving meaningful gaps for an agent deciding whether to call it.

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

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

Schema description coverage is 100%, so channelId and messageId are already documented as Discord channel/message IDs. The description adds no format or targeting detail beyond the schema, which is the expected baseline 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 (Remove) and resource (reactions) with scope (all, from a message), so an agent knows exactly what it does. It doesn't explicitly contrast with the sibling remove_reaction (which removes one specific reaction), so the boundary relies on inference.

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

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

No guidance on when to use this versus remove_reaction or add_reaction, no prerequisites, and no mention of required permissions. The agent must infer the use case from the name alone.

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

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

No annotations are provided, so the description carries the full burden. It implies a mutation but discloses nothing about permission requirements, that the rule takes effect immediately, or any rate limits. The examples are the only added behavioral hint.

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 wasted words; the verb and resource come first and the examples are a tight parenthetical.

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

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

For a 10-parameter mutation tool with no annotations and no output schema, the description is too thin. It omits the important relationship that triggerType determines which params apply (keywordsCsv for KEYWORD, mentionLimit for MENTION_SPAM), leaving the agent to infer conditional parameter usage from schema text alone.

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 ten parameters, including defaults and enum values. The description's examples of triggers loosely map to the triggerType enum but add no syntax or format detail beyond the schema.

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

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

States a specific verb (create) and resource (AutoModeration rule) and gives concrete examples of trigger categories. It is distinguishable from edit_automod_rule, delete_automod_rule, and list_automod_rules, though it never names those siblings explicitly.

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

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

No guidance on when to create a rule versus edit an existing one, no mention of required bot permissions (Manage Server), and no note that it needs a guild context. Usage is only implied by the verb.

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

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

No annotations are provided, so the description carries the full behavioral burden, yet it only restates the mutation implied by the name. It says nothing about required permissions, whether the category is created at the end of the list by default, what happens on name collisions, or what is returned. For an unannotated write tool this is a real 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?

A single, front-loaded sentence with zero padding — efficient and easy to scan. It is arguably too terse for a mutation tool, but there is no wasted language.

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 no permissions or failure-mode context, the definition leaves an agent short of what it needs to call this write tool confidently. The schema covers inputs, but the behavioral surface of a category-creating mutation is essentially undocumented.

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 four parameters (name, reason, guildId, position) are each documented with their purpose, including the DISCORD_GUILD_ID default and audit-log semantics. The description adds no parameter meaning beyond that, which is the expected baseline when the schema does the work.

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

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

The description states a specific verb and resource ('Create a channel category'), so an agent immediately knows the operation. However, it does no sibling differentiation despite a crowded namespace of channel/category creators (create_text_channel, create_voice_channel, create_forum_channel, edit_category, delete_category), and it doesn't clarify that a category is a container rather than a channel.

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. requires Manage Channels permission), and no pointer to alternatives such as edit_category or create_text_channel for placing channels inside a category. The agent must infer all routing from the name alone.

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

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

No annotations, so the description carries full burden. It usefully discloses the 256KB size limit and accepted input formats, but omits whether this is a privileged mutation, what happens on duplicate names, and what the response contains.

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

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

A single tight sentence with no filler; the operation, source, and size constraint are all front-loaded.

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

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

For a 5-parameter mutation tool with no annotations and no output schema, the description does not cover permission requirements, role-restriction behavior, or the guild-default behavior of guildId/reason audit logging. It is adequate, not complete.

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

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

Schema coverage is 100%, so all five parameters are already documented in the schema, including the URL/base64 format for attachmentUrlOrBase64. The description adds only the 256KB constraint and nothing on new/optional params like rolesCsv.

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

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

Specific verb (Upload/create) plus resource (custom emoji), and the word 'new' implicitly distinguishes it from edit_emoji and delete_emoji in the sibling set. Source formats and size cap are stated up front.

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 it (creating a new emoji from an image), but never names alternatives like edit_emoji or list_emojis, nor does it state prerequisites such as needing emoji-management permissions. Usage is inferable but not guided.

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, yet it discloses nothing beyond the bare action: no permission requirements, no note that a name collision fails, no indication of what the channel's default state is. For a mutation tool with zero annotation coverage this is a real 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?

A single, tight sentence with the action front-loaded. Nothing is wasted, though there is also very little substance to waste.

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

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

For an 8-parameter mutation tool with no annotations and no output schema, the description should say more about effects, prerequisites (e.g., Manage Channels permission), and error behavior. What is present is correct but far from complete.

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

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

Schema description coverage is 100%, so the schema already documents all 8 parameters (name, topic, nsfw, slowmode, position, categoryId, guildId, reason). The description adds no parameter-level detail, which is acceptable given the schema baseline of 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?

The description uses a specific verb+resource ("Create a new forum channel") and scopes it to "community discussions and threads". It is clearly distinguishable from siblings like edit_forum_channel or create_forum_post, though it does not explicitly name an alternative.

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

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

No when-to-use or when-not-to-use guidance. The agent is not told how this differs from create_text_channel/create_voice_channel/create_category, or when a forum channel is the right choice over a forum post. Usage must be inferred.

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 burden but only implies the message is required. It omits permission requirements, whether the target channel must already be a forum channel, rate limits, and any side effects of post creation.

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 it is short enough that it does not exploit the room to add needed behavioral context.

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

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

For a mutation tool with no annotations and no output schema, the description is minimally adequate: parameters are fully covered by the schema, but auth expectations and behavioral consequences are left unstated, so an agent lacks guidance on prerequisites.

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 four parameters (title, message, channelId, tagIdsCsv) are already documented in the schema. The description adds only loose mapping ("initial message and optional tags"), 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 ("Create a new forum post (thread)") and clarifies it carries an initial message and optional tags. It is distinguishable from siblings like create_thread and create_forum_channel, though it does not explicitly name them.

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

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

No when-to-use, when-not, or alternative guidance is given. An agent cannot tell from the text whether to use this versus create_thread or create_forum_channel, nor what preconditions (e.g. channel must be a forum channel) apply.

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 hints at expiration and usage limits (which are really parameter semantics) but says nothing about required permissions (e.g. Manage Channels), whether the invite is bot- or user-authored, or what the operation returns. For an unannotated creation tool this is a notable 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?

A single efficient sentence with the core action front-loaded. Nothing is wasted, though it is arguably too terse to carry the disclosure burden it must.

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?

Parameters are fully covered by the schema, but with no annotations and no output schema the description should compensate by stating permission requirements and the nature of the returned invite code/URL. It omits these, so it is only minimally adequate 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 description coverage is 100% and all six parameters are well documented in the schema itself. The description only echoes expiration and usage limits, adding no format or behavioral detail beyond what the schema already provides; 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 (Create) and resource (invite link for a channel) and notes it supports expiration and usage limits. It is clear what the tool does, but it does not differentiate itself from invite-related siblings like generate_bot_invite_url, list_invites, or get_invite_details.

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 the other invite tools in the sibling list. No prerequisites or contextual conditions are given, leaving the agent to infer usage entirely from the name.

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

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

With no annotations, the description carries the full behavioral burden, yet it says nothing about required permissions (e.g., SEND_MESSAGES), which channel types accept polls, whether the poll can be edited after creation, or what happens when the duration expires. The only behavioral hint is 'official interactive', which distinguishes it from mock polls.

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 the brevity is partly the source of the missing guidance rather than disciplined editing.

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

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

For a five-parameter mutation tool with no annotations and no output schema, the description covers the core action but omits the operational context an agent needs: required permissions, valid target channel types, and the relationship to the polling siblings. Adequate but with clear gaps.

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

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

Schema description coverage is 100%, so the schema already documents the question length limit, answer count range, duration minimums/maximums, and multiselect default. The description adds no format or syntax detail 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 and resource ('Create ... Discord poll') and clarifies it is the native interactive poll type rather than an emoji-reaction workaround. It does not distinguish itself from the sibling 'end_poll' (or 'get_poll_answer_voters'), so an agent must infer the lifecycle relationship.

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

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

No when-to-use guidance, no prerequisites, and no mention of alternatives such as sending a message with reaction options or closing a poll with 'end_poll'. The agent gets only the bare action.

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

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

No annotations are provided, so the description carries the full behavioral burden. For a mutation tool it omits permission requirements (e.g. Manage Roles), the position of the newly created role in the hierarchy, and what the operation returns, adding essentially nothing beyond 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 short, front-loaded sentence with no redundant clauses. It is efficient, though its brevity reflects under-specification rather than disciplined trimming.

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

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

For an 8-parameter mutation tool with no annotations and no output schema, one generic sentence is inadequate. Critical context such as required bot permissions, how permissionsRaw/permissionsNames interact, and return behavior 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 every parameter is already documented in the input schema and the baseline is 3. The phrase 'custom properties' gestures at optional fields but adds no meaning 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?

States a specific verb and resource ('Create a new role on the server'), which is clear. However, 'with custom properties' is vague filler and the description does not differentiate this from siblings like edit_role or assign_role, 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 when-to-use guidance and no mention of alternatives. An agent is left to infer that this is the creation step versus edit_role for modification, with no explicit routing 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?

No annotations are provided, so the description carries the full burden and discloses almost nothing beyond the entity-type list. It does not state that this is a mutating operation, what permissions are required, that the event is created immediately and visible to the server, or any rate-limit behavior.

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

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

One short, front-loaded sentence with no filler. It is efficiently written, though its brevity reflects the small amount of information conveyed rather than disciplined coverage of a complex tool.

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

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

For a 9-parameter mutation tool with no annotations and no output schema, the description is thin: it omits the conditional field relationships and any behavioral context. The 100%-covered schema compensates for parameter gaps, making this minimally adequate but not complete.

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

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

Schema description coverage is 100%, so the baseline is 3; the schema already documents every parameter including the conditional requirements (channelId for STAGE/VOICE, location for EXTERNAL). The description's mention of Stage/Voice/External merely restates the entityType enum rather than adding format or constraint detail.

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 ('Schedule') and resource ('server event') and enumerates the three event types (Stage, Voice, External). It does not name or distinguish itself from the close siblings edit_scheduled_event, delete_scheduled_event, or list_scheduled_events, but the verb itself makes the create intent 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 guidance on when to use this versus the other scheduled-event tools, no prerequisites (e.g. needing a Stage/Voice channel first), and no mention of required permissions. The agent must infer everything about invocation context from the name alone.

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

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

No annotations are provided, so the description carries the full burden, and it does disclose one important behavioral constraint (the 10-guild bot limit) that an agent could not infer from the schema. However, it omits required bot permissions, what happens on failure (error shape), whether the bot auto-joins the created guild, and what the response contains.

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

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

Two tight sentences with zero filler: the purpose leads and the critical operational caveat follows. Nothing is redundant with the name or schema.

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

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

With no annotations and no output schema, the description still covers purpose plus the single biggest gotcha for this operation, which is strong for a 2-parameter creation tool. It is slightly short of complete because it never says what a successful call returns (the created guild object) or what permissions/errors to expect.

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

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

Schema description coverage is 100% for both parameters (name, iconUrl), including the base64/data-URI detail for the icon, so the schema already does the heavy lifting. The description adds nothing about parameter format or constraints, 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 opens with a specific verb+resource ('Create a new Discord guild'), which is unambiguous and easily separated from the many other create_* siblings that target channels, roles, emojis, threads, or invites. The clarifying note reinforces that guild == server, matching siblings like get_server_info and list_servers.

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

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

It gives a concrete precondition that governs when the call will succeed: bot accounts can only create guilds while in fewer than 10 guilds. That effectively states a when-not condition, but it does not mention permission requirements or any alternative approach (there is no sibling that creates a guild, so alternatives are moot).

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 provided, the description carries the full behavioral burden, and it does not say this is a mutating/creating operation requiring channel-management permissions, what the guildId default resolves to, or what evidence the caller gets back. For a creation tool with zero annotation coverage this is a meaningful 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?

A single front-loaded sentence with no filler; the action and the resource it creates are stated immediately. Nothing is wasted, though brevity here reflects an absence of detail rather than tight editing.

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

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

For a 5-parameter mutating tool with no annotations and no output schema, the description omits permission requirements, guild/category resolution behavior, and any sense of what is returned or what side effects occur. The rich schema covers inputs, but the behavioral side is entirely unaddressed.

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

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

Schema description coverage is 100%, so every parameter (name, reason, bitrate, guildId, categoryId) is already documented in the schema, meeting the baseline of 3. The description adds nothing about parameter usage beyond what the schema states, but no compensation is needed.

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 new stage channel') and adds the intended use case ('audio events and presentations'), which implicitly distinguishes it from create_voice_channel and create_text_channel. It does not explicitly name those siblings, 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?

There is no guidance on when to choose this over the other channel-creation siblings (create_voice_channel, create_text_channel, create_forum_channel, create_category), nor any prerequisite or ordering information (e.g. needing a category first). The intended-use clause is descriptive, not 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?

With no annotations provided, the description carries the full burden. It usefully discloses hard constraints on the uploaded asset (PNG or APNG, max 512KB, exactly 320x320), which is real behavioral value, but it says nothing about required permissions, failure behavior, or reversibility for what is clearly a write 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 tight sentence that leads with the action and appends the constraints. Nothing is wasted and the most important information is front-loaded.

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

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

For a mutation tool with no annotations and no output schema, the description covers the asset constraints adequately but omits permission requirements and any indication of what a successful or failed call returns. It is minimally viable but has visible gaps.

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

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

Schema description coverage is 100%, so all six parameters are already documented in the schema, establishing a baseline of 3. The description adds format/size constraints that the schema lacks, but nothing about required-vs-optional behavior or the audit 'reason' 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 ('Upload a new custom sticker'), which clearly separates it from siblings like list_stickers, get_sticker_details, and delete_sticker. It does not explicitly name those siblings, so it earns a 4 rather than 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 prerequisites, and no mention of alternatives. The constraint clause (PNG/APNG, 512KB, 320x320) is a validation rule rather than usage guidance, so an agent gets no routing help.

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 at all, the description carries the full behavioral burden for a mutating operation and discloses almost nothing: no permission requirements, no mention that this is irreversible, no note that guildId defaults to the DISCORD_GUILD_ID environment variable, and no description of what the created channel returns.

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

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

A single short sentence with the action and resource front-loaded and zero filler. It is efficient, though arguably so terse that it omits useful framing rather than being an example of well-structured completeness.

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

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

For an eight-parameter mutating tool with no annotations and no output schema, the definition is under-specified: it does not cover permissions, defaults, failure modes, or the resulting channel object. The rich schema partly compensates on parameters, but the behavioral gap remains.

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

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

Schema description coverage is 100%, with all eight parameters individually documented (name, nsfw, topic, reason, guildId default, position, slowmode range, categoryId). The description adds no parameter meaning 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 verb and resource ('Create a new text channel') and the scope ('in a server'), and the word 'text' implicitly distinguishes it from create_voice_channel, create_stage_channel, and create_forum_channel. However, it never names those alternatives, so an agent must infer the distinction from the name alone.

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

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

No guidance about when to use this rather than create_voice_channel, create_stage_channel, create_forum_channel, or create_category, all of which are near neighbors in the sibling list. No prerequisites (e.g. required permissions such as Manage Channels) or post-creation steps are mentioned.

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

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

No annotations are provided, so the description carries the full behavioral burden. It says nothing about required permissions (e.g., thread-creation rights), whether the creator auto-joins the thread, or side effects. The default auto-archive behavior lives only in the schema, not the prose.

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 slightly terse given the tool's five parameters and mutation semantics.

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 is the only place to convey behavioral context, and it omits permission requirements and post-creation effects. It is minimally adequate because the schema fully documents all parameters, but incomplete 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 description coverage is 100%, so baseline is 3. The description adds only a mild hint by mapping messageId presence to 'message thread' creation, but adds no syntax or format detail beyond the schema's own descriptions.

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 ('Start a new thread') and distinguishes the two creation modes: standalone channel thread vs. a thread attached to an existing message. That differentiation is useful, though it doesn't explicitly contrast with adjacent siblings like join_thread or modify_thread.

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

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

The phrase 'in a text channel or from a specific existing message' implies the applicable context, but there is no explicit when-to-use/when-not guidance or routing to alternatives such as create_forum_post for forum posts. 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?

No annotations are provided, so the description carries the full burden. It doesn't state the required MANAGE_CHANNELS permission, where the channel is positioned in the channel list, whether the operation is reversible, or anything about the created object's identifier — all material for a mutation tool with zero annotation 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?

A single, clean sentence with the action and resource front-loaded and 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 6-parameter mutation tool with no annotations and no output schema, the definition is too thin — it omits permission requirements, DEFAULT guild scoping behavior, and how the created channel is returned or identified.

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

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

Schema description coverage is 100%, so every parameter (name, reason, bitrate, guildId, userLimit, categoryId) is already documented in the schema. The description adds no syntax, defaults, or constraints beyond that, which is the expected baseline 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 (create) and resource (voice channel) in a server, which cleanly separates it from sibling channel creators like create_text_channel, create_stage_channel, and create_forum_channel. 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?

No guidance on when to use this versus the other create_*_channel tools, no prerequisites, and no mention of required permissions. The agent must infer all selection logic from the resource type alone.

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

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

With no annotations, the description carries the full behavioral burden. It says nothing about required permissions (e.g. Manage Webhooks), that the operation mutates server state, whether the created webhook's token is returned, or any rate-limit behavior. 'Create' implies mutation but no consequences or authority requirements are 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?

A single compact sentence with the key facts front-loaded and no wasted words. It is efficient, though its brevity borders on under-specification rather than ideal density.

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

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

There is no output schema, so return values need not be described, and all three parameters are documented in the schema. However, for an unannotated mutation tool, the missing permission/authority and lifecycle context leaves the definition only minimally adequate.

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

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

Schema description coverage is 100% (name, channelId, reason are all documented in the schema), so the baseline is 3. The description adds no syntax, format, or meaning beyond what the schema already provides — notably it never explains the 'reason' audit-log 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 ('Create a new webhook') and adds scope ('on a specific text channel'), which is more than a restatement of the name. It does not, however, distinguish itself from siblings like list_webhooks, delete_webhook, or send_webhook_message, which an agent may confuse when choosing among webhook operations.

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

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

No guidance on when to use this versus the other webhook tools, no note that the channel must be a text channel the bot can manage, and no mention of prerequisites. The agent must infer all selection context from the sibling names alone.

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

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

With no annotations, the description carries the full burden, and 'Permanently' usefully discloses that the operation is irreversible. However, it omits the permission scope required (e.g. Manage Server), the audit-log behavior tied to the reason parameter, and any warning that the rule cannot be recovered.

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

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

A single short sentence that is front-loaded with the verb and resource and contains no filler. It is efficient, though arguably too terse for a destructive operation where a second sentence about irreversibility would 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 simple single-resource delete with full schema coverage and no output schema, the core information is present. The gap is behavioral: no annotation coverage means the description should have addressed permission requirements and destructive consequences, which it only partially touches via '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?

Schema description coverage is 100%, so all three parameters (ruleId, reason, guildId) are already documented in the schema. The description adds no syntax, default, or format detail beyond it, so the baseline of 3 applies.

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

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

States a specific verb (delete) and resource (AutoModeration rule) with an added qualifier (Permanently), so an agent can distinguish it from the sibling edit_automod_rule, create_automod_rule, and get_automod_rule. It does not name those siblings 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?

The description gives no when-to-use guidance, no prerequisites, and no mention of alternatives or consequences. For a destructive operation this is a notable omission, leaving the agent to infer everything about when deletion is appropriate.

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 burden. It usefully discloses one important side effect — contained channels become unparented rather than deleted — but says nothing about irreversibility, required permissions, or whether the operation can be undone.

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

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

A single sentence with the action front-loaded and the side effect in a compact parenthetical. Every element 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 small two-parameter delete tool with full schema coverage and no output schema, the description covers the essential operation and its key side effect. Only auth/irreversibility details are absent.

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

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

Schema description coverage is 100%, so both parameters (categoryId, reason) are already documented in the schema. The description adds nothing about parameter formats or constraints, so the baseline 3 applies.

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

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

States a specific verb and resource ('Delete a channel category'), which is unambiguous. It does not explicitly distinguish itself from siblings like edit_category or delete_channel, but the destructive scope is clear from the verb alone.

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

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

There is no guidance on when to use this versus edit_category or delete_channel, nor any prerequisites (e.g. permissions needed). The parenthetical warns of a side effect, which is useful context but not usage routing.

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

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

With no annotations provided, the description carries the full behavioral burden. It does not state that deletion is irreversible, what permissions or hierarchy position are required, or what happens to the channel's messages and threads, which are essential facts for a destructive 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?

The single sentence is front-loaded and free of padding, but its brevity reflects under-specification rather than disciplined conciseness for a destructive tool with no annotations.

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

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

For a destructive mutation with no annotations and no output schema, the description is too thin. It omits irreversibility, permission requirements, and side effects on channel content, leaving the agent without enough context to invoke it safely.

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 channelId and reason (including its audit-log purpose) are already fully documented in the schema. The description adds nothing 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?

The description states a specific verb (Delete) and resource (channel), clearly separate from sibling delete_channel_permission and delete_category. It does not, however, explicitly differentiate itself from those closely named 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 alternatives such as edit_channel, delete_category, or delete_channel_permission, and no mention of prerequisites or exclusions. The agent must infer everything from the name alone.

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

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

No annotations are provided, so the description carries the full behavioral burden. It says a deletion occurs, but never states required bot permissions, whether the operation is irreversible, what happens to the channel's effective permissions afterward, or how it behaves when no overwrite exists for the target. For an unannotated mutation tool this is a substantial 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?

A single front-loaded sentence with the verb first and zero padding. Efficient, though it is a bare minimum of text rather than a well-rounded definition.

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

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

A destructive three-parameter mutation with no annotations and no output schema needs more: auth requirements, reversibility, and the relationship to the upsert_* siblings are all absent. The description is not sufficient for an agent to call this confidently in context.

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% (reason, targetId, channelId each documented), so the baseline is 3. The description's 'for a role or member' and 'from a channel' loosely mirror targetId and channelId but add no format or constraint detail beyond the schema.

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

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

Clear specific verb (Delete) plus resource (a permission overwrite for a role or member on a channel), and the 'role or member' phrasing signals scope. It does not name the sibling it complements (upsert_role_channel_permissions / upsert_member_channel_permissions) or the list tool, so an agent gets the action but no explicit differentiation.

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

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

No when-to-use guidance, no prerequisites, and no reference to the sibling upsert_* tools that create the very overwrites this deletes. The agent must infer the workflow entirely from the name.

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

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

No annotations are provided, so the description carries the full behavioral burden. 'Previously sent' hints that only the bot's own messages may be deletable, but there is no disclosure of irreversibility, required permissions, or failure modes for a destructive mutation.

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

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

A single front-loaded sentence with no waste. It is efficient, though it trades away completeness for brevity.

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

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

For a destructive mutation with no annotations and no output schema, the description is too thin. It should disclose irreversibility, permission requirements, and whether the DM must be bot-authored.

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

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

Schema description coverage is 100%, with userId ('Discord User ID') and messageId ('Message ID to delete') both documented. The description adds no syntax or format 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 verb (delete) and resource (direct message) with scope ('previously sent ... to a user'), which distinguishes it from the sibling delete_message that operates on channel messages. Clear enough for an agent to route between the two.

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 offers no when-to-use context, no exclusions, and no reference to alternative tools such as delete_message or bulk_delete_messages. Only the implied 'to a user' hints at a scope 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 are provided, so the description carries the full behavioral burden. It discloses only one trait, permanence, and omits required permissions, whether the emoji disappears from existing message reactions, and whether the operation is recoverable.

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, and the most important word ('Permanently') appears early. It is efficient, though the same brevity leaves behavioral gaps that a slightly longer description could close.

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

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

For an irreversible destructive operation with zero annotations and no output schema, the description should state permission requirements and side effects. Instead it offers one sentence, leaving the agent to infer everything beyond irreversibility.

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

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

Schema description coverage is 100%, with emojiId, guildId, and reason each documented in the schema itself, so the baseline of 3 applies. The description adds no format, default, or semantic detail beyond what the schema already states.

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

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

The description states a specific verb ('Permanently delete') and resource ('a custom emoji on the server'), which cleanly separates it from sibling create_emoji and edit_emoji. It stops short of explicitly naming those siblings or the scope qualifier, so a 4 rather than 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 (e.g., required permissions), and no routing to alternative tools such as edit_emoji when the goal is modification rather than removal. The phrase 'Permanently delete' hints the action is irreversible but does not frame it as a usage caution.

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 disclosure burden. It conveys the destructive/irreversible nature ('can no longer be used') and the audit-log purpose of the reason param is visible in the schema, but it says nothing about required permissions, who may revoke, or permanence of the effect.

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

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

A single front-loaded sentence with zero waste; the outcome is stated immediately after the action.

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

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

For a simple two-parameter delete operation with full schema coverage and no output schema, the description is largely sufficient. The only gap is the absence of annotation coverage for permissions/safety, which it does not compensate for.

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 (inviteCode with example format, reason as audit-log reason) are fully documented in the schema. The description adds no parameter-level meaning, so the baseline of 3 applies.

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

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

States a specific verb (revoke/delete) and resource (invite link) and adds the consequence ('so it can no longer be used'), which clearly distinguishes it from the create_invite, list_invites, and get_invite_details 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?

The description implies the general use case of revoking an invite, but gives no explicit when-to-use guidance, no alternatives, and no exclusions or prerequisites. The agent must infer 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 behavioral burden. It says 'delete' but omits whether the deletion is permanent, what permissions are required, or what happens to the message. This is a significant gap for a destructive mutation.

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

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

A single, front-loaded sentence with 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 destructive operation with no annotations and no output schema, the description is incomplete. It should at least state permanence, permission requirements, or interactions with bulk deletion.

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 channelId, messageId, and the optional reason parameter. The description adds no parameter detail beyond what the schema provides; 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 clear verb+resource: 'Delete a specific message from a channel'. This distinguishes it from siblings like delete_direct_message and edit_message, though it doesn't explicitly name alternatives.

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

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

No guidance on when to use this vs alternatives such as bulk_delete_messages or delete_direct_message, nor any preconditions or warnings. The agent is left to infer usage from the name alone.

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

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

With no annotations at all, the description carries the full burden. 'Permanently' is a genuine disclosure that the operation is irreversible, which is the highest-value behavioral fact here. It says nothing about required permissions, whether members holding the role lose it, or what happens to existing channel permission overwrites tied to the role.

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

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

One sentence, front-loaded with the action and its key modifier. Nothing is wasted, no filler, no 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 destructive mutation with zero annotation coverage and no output schema, the description is too thin. It omits permission requirements, cascading effects on members and channel overwrites, and any distinction from remove_role, leaving the agent under-informed before an irreversible call.

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

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

Schema description coverage is 100%, so roleId, reason, and guildId are all documented in the schema itself with useful descriptions (including the DISCORD_GUILD_ID default). The description adds no parameter meaning beyond that, so the baseline of 3 applies.

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

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

States a specific verb and resource ('delete a role from the server'), which is unambiguous on its own. It does not, however, distinguish itself from its nearest sibling remove_role, which strips a role from a member rather than destroying the role object — a distinction an agent must infer.

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

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

There is no statement of when to use this versus remove_role or edit_role, and no prerequisites mentioned. The sibling list contains both delete_role and remove_role, so the absence of routing guidance is a real hazard.

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 must carry the behavioral burden. 'Permanently delete' discloses irreversibility, which is valuable. However, it omits critical operational details: whether this requires specific permissions, what happens to attendees/RSVPs, whether the event is recoverable, and what the response looks like. The single phrase 'permanently delete' is the only behavioral hint.

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

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

A single, front-loaded sentence with zero wasted words. The critical information ('permanently delete') is stated immediately.

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

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

For a destructive mutation tool with no annotations and no output schema, the description is minimally adequate. It states the operation but lacks essential context about permissions, side effects on attendees, and irreversibility beyond the word 'permanently'. The agent has enough to call it but not enough to call it safely or understand the full impact.

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 schema fully documents both parameters (eventId, guildId). The description adds no parameter information 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 ('delete') and resource ('scheduled event') with an explicit permanence qualifier. Clearly distinguishable from siblings like edit_scheduled_event or list_scheduled_events.

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

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

No guidance on when to use this tool versus alternatives like edit_scheduled_event (which could cancel) or how it differs from editing. The description provides no usage context, leaving the agent to infer everything from the name.

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

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

No annotations are provided, so the description carries the full burden. It usefully discloses that deletion is permanent/irreversible, but omits permission requirements, whether the sticker must be guild-owned, and error behavior for invalid IDs. Partial behavioral disclosure only.

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

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

A single front-loaded sentence with zero filler; the key irreversible nature of the operation is stated immediately.

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

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

For a destructive mutation with no annotations and no output schema, the description covers the action and its permanence but leaves gaps around permissions and preconditions. Adequate but not complete.

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

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

Schema description coverage is 100%, with stickerId, guildId (defaults to DISCORD_GUILD_ID), and reason (audit log) all documented in the schema. The description adds nothing 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 and resource ('permanently delete a custom sticker'), which is clear and unambiguous. It does not explicitly differentiate from sibling tools like delete_emoji or create_sticker, but the resource is specific enough that an agent can distinguish 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 guidance on when to use this tool versus alternatives, no prerequisites (e.g. sticker must belong to the target guild), and no mention of required permissions. The description only states what the tool does, not when to reach for 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 burden for a destructive mutation. It does not state that deletion is permanent/irreversible, what permissions are required, or whether the operation succeeds on an already-deleted webhook. It only restates the deletion action.

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

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

A single short, front-loaded sentence with no wasted words. It is efficient, though arguably too terse given the behavioral gaps it leaves uncovered.

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

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

This is a destructive mutation with no annotations and no output schema, and the description omits irreversibility, permissions, and error/return behavior. For a delete operation the description is significantly under-specified.

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%, documenting both webhookId and the optional audit-log reason, so the schema does the heavy lifting. The description only implies webhookId via 'by ID' and adds nothing about the reason parameter, so baseline 3 applies.

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

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

The description states a specific verb (Delete) and resource (webhook) plus the identifier used, so the agent knows exactly what operation is performed. It does not differentiate from siblings create_webhook, list_webhooks, or send_webhook_message, but the name/verb make the distinction obvious enough.

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 alternatives, nor any prerequisites such as needing a valid webhookId or ownership/permission. The agent gets no when-to-use or when-not-to-use 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 behavioral burden. It implies a voice-state mutation but does not disclose permissions required, side effects, reversibility, or what happens if the user is not in a voice channel.

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 zero wasted words. It immediately identifies the action and target resource.

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 omits prerequisites, alternatives, permission requirements, and behavioral details an agent needs to invoke it safely and 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 userId, guildId, and reason are already documented in the schema. The description does not add any parameter-specific meaning beyond what the structured fields provide, making 3 the appropriate baseline.

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

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

The description states a specific verb and resource: disconnect a member from their current voice channel. It is distinguishable from move_voice_member and modify_voice_state in intent, but it does not explicitly name alternatives or clarify sibling boundaries.

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 move_voice_member, modify_voice_state, or kick_member. The description only says what the tool does, leaving all usage context implicit.

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 says 'Edit' (implying mutation) and mentions the two fields that can be changed, but does not disclose permission requirements, whether changes are reversible, audit-log implications (there is a 'reason' param), or what happens to other rule properties. This is a significant gap for a mutation tool with zero annotation 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?

A single, tight sentence with the parenthetical enumerating modifiable fields. Front-loaded verb-resource, no waste.

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

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

For a mutation tool with no annotations and no output schema, the description is too thin. An agent needs to know permission requirements, what happens to unspecified fields, and the audit-log (reason) semantics. Five parameters, 100% schema coverage helps, but the behavioral void is not filled.

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 in the schema. The description adds only marginal semantics by listing the two editable fields; it doesn't explain the 'reason' audit-log parameter or the 'guildId' default behavior beyond what the schema provides. 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 names a specific verb (Edit) and resource (AutoModeration rule), and clarifies the two editable dimensions (name, enabled state). It distinguishes from delete_automod_rule and create_automod_rule, though it doesn't mention get_automod_rule or list_automod_rules as related read 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?

Usage is implied – clearly for modifying an existing rule – but there are no explicit when-to-use vs. alternatives statements, no prerequisites (e.g., need manage-guild permissions), and no conditions for choosing this over delete-and-recreate.

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 burden, and it discloses almost nothing: no permission requirements, whether the audit-log reason is required or optional, or what happens to channels inside the category when position changes. Only the bare mutation intent is conveyed.

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

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

A single front-loaded sentence with zero filler. It is appropriately sized for the operation, though the brevity comes at the cost of useful detail rather than being tight but complete.

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

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

A four-parameter mutation tool with no annotations and no output schema needs more than one clause: it should state at minimum that categoryId is required, that name/position are optional edits, and what the reason field is for. The description omits all of this.

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 four parameters including categoryId and reason. The description names two of them (name, position) but adds no format, constraint, or reconciliation semantics beyond the schema 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 (edit) and resource (category) plus the two mutable fields, so it is clearly distinguishable from create_category and delete_category. It lacks any scope detail (e.g., server context or what a position change affects).

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 edit_channel for non-category channels. The agent must infer applicability entirely from the name and 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?

With no annotations, the description carries the full behavioral burden, yet it discloses nothing: not whether the edit is partial (omitted fields left unchanged), what permissions are required, whether changes are reversible, or how the audit-log 'reason' interacts with the operation. For a 10-parameter mutation tool this is a significant 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?

A single efficient sentence with the resource front-loaded and no filler. It is appropriately sized, though at the cost of leaving out any behavioral context.

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

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

A 10-parameter mutation tool with no annotations and no output schema needs the description to explain permissions, partial-update semantics, and side effects; instead it offers one sentence. The schema alone cannot tell an agent whether unspecified fields are preserved or cleared.

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

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

Schema description coverage is 100%, so the baseline is 3. The phrase 'text, voice, or stage channel' is the only added meaning, implicitly telling the agent which of the type-specific fields (topic vs. bitrate/userLimit) apply to which channel kind.

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 (edit) and resource (channel), and narrows the scope to text, voice, or stage channels. However, it never distinguishes itself from close siblings like edit_forum_channel, edit_category, or move_channel, which an agent could easily confuse it with given a 100+ tool 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?

There is no when-to-use guidance, no mention of prerequisites (e.g., Manage Channels permission), and no routing to alternatives such as move_channel for repositioning or edit_forum_channel for forum channels. The agent must infer all of this from the 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?

No annotations are provided, so the description carries the full burden. It states the operation is an edit (a mutation) but doesn't disclose permissions required, whether edits are allowed on others' messages, if history is tracked, or what happens on failure. Significant behavioral gaps 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?

A single, clear sentence with no wasted words. It is appropriately sized for the tool's simplicity and front-loads the action.

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 it's a mutation tool with no annotations and no output schema, the description is too sparse. It should explain permissions, return behavior, or error conditions to be truly complete for an agent.

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

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

Schema coverage is 100%, so all three parameters (userId, messageId, newMessage) are already documented in the schema. The description adds no additional meaning beyond what the schema provides. Baseline 3 is appropriate when 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?

Clear verb 'Edit' and resource 'direct message' with a specific scope ('previously sent'). However, it does not distinguish from siblings like edit_message (likely for channel messages) or other DM tools like send_direct_message and delete_direct_message.

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

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

No explicit when-to-use or when-not-to-use guidance. The phrase 'previously sent' implies the message must already exist, but there's no mention of alternatives like edit_message for server messages or restrictions on which messages can be edited.

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 signals mutation ('Edit') and names what can change, but omits whether this requires specific permissions, whether rolesCsv replaces or appends to existing restrictions, whether changes are reversible, and audit/rate-limit behavior.

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

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

A single tight sentence that front-loads the action and enumerates the editable properties with zero padding. It is appropriately sized, though its brevity borders on under-specification given the untold behavioral context.

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

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

For a mutation tool with no annotations and no output schema, the description does the minimum: it says what it edits but not how the operation behaves, what it returns, or what permissions it needs. The rich schema covers parameters, but behavioral completeness is lacking.

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 five parameters are documented in the schema (including 'empty string to allow all' semantics for rolesCsv). The description adds no format or edge-case detail beyond mapping to two of the fields, so it sits at the 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 clear verb (edit) plus resource (custom emoji) and specifies the mutable fields (name, restricted roles). This distinguishes it from the sibling create_emoji/delete_emoji/list_emojis, though it never names those siblings explicitly.

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

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

There is no when-to-use guidance, no mention of prerequisites (e.g., the MANAGE_EMOJIS permission Discord requires), and no routing to alternatives such as delete_emoji or get_emoji_details. The agent must infer usage 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 behavioral burden. It is a mutation tool, yet it never states required permissions (e.g. MANAGE_CHANNELS), whether the edit is partial or full-replace, what happens to unspecified settings, or that the reason parameter feeds the audit log — all significant gaps for a write 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 with a parenthetical field list and no wasted words. It is efficient, though the enumeration is redundant with the schema and the sentence is arguably too sparse for a 10-parameter mutation tool.

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

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

For a 10-parameter mutation tool with no annotations and no output schema, the description omits permissions, partial-update semantics, the audit-log role of reason, and the empty-string convention for categoryId unparenting. It is far too thin to fully orient an agent.

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

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

Schema description coverage is 100%, so every parameter is already documented, including enum values for defaultSort and defaultLayout and slowmode's 0-21600 range. The description merely echoes five of the ten fields without adding format, constraint, or interaction detail, 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 (Edit) and resource (forum channel settings), and enumerates the editable fields, so the agent knows it targets forum-channel configuration. It does not differentiate from the closely related sibling edit_channel, which an agent could easily confuse with this one.

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

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

The description gives no when-to-use guidance, no distinction from edit_channel or create_forum_channel, and no prerequisite information. Nothing tells the agent under what circumstances this tool should be chosen over its 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?

No annotations are provided, so the description carries the full burden. It discloses the bot-authored constraint and that mention resolution is optional/automatic, which is meaningful behavior. But it omits what happens on failure (e.g., editing a non-bot message), required permissions, and whether the edit is idempotent.

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 tight sentence with the core action and scope constraint front-loaded. No filler, though it is brief enough that some clarifying detail could have been added without bloat.

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 should compensate more. It covers the essential action and the mention-resolution option, but leaves error conditions, permission requirements, and result format 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 description coverage is 100%, so all four parameters are already documented, including resolveMentions. The description only restates the mention-resolution behavior at a high level and adds nothing about formats or edge cases beyond the schema. Baseline 3 applies.

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

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

States a specific verb (edit) and resource (message) plus an important scope constraint: 'previously sent by the bot'. This distinguishes it from editing arbitrary messages, though it does not name the closest sibling edit_direct_message to route the agent 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 phrase 'previously sent by the bot' implies a usage restriction (the bot can only edit its own messages), which is useful context. However, there is no explicit when-to-use vs. when-not guidance and no reference to edit_direct_message or send_message as 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?

No annotations are provided, so the description carries the full burden. It says only 'edit' without disclosing whether unspecified fields are preserved or cleared (partial vs. full update), what permissions are required, whether changes are reversible, or that the 'reason' field feeds an audit log. For a mutation tool this is a substantial 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?

It is a single front-loaded sentence with no wasted words, but for a 10-parameter mutation tool it is under-specified rather than genuinely concise, and the grammar ('an existing role settings') is imprecise.

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 10 parameters (only roleId required, implying a partial-update semantic that is never explained), the definition leaves key calling questions unanswered—most notably what happens to fields not passed and whether permissions are replaced or merged.

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 every parameter is self-documented (name, color, hoist, position, permissionsRaw, permissionsNames, audit reason, etc.). The description adds nothing 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 verb (Edit) and resource (an existing role's settings and permissions), which is enough to separate it from create_role, delete_role, and get_role_info by implication. However, it never explicitly names or contrasts those siblings, and the phrasing 'role settings' is slightly loose.

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 when to prefer create_role versus edit_role, and no stated prerequisites (e.g., permission to manage roles or hierarchy constraints). The agent must infer all usage 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. It discloses status-transition intent (start/complete/cancel) but says nothing about permissions required, whether omitted fields are left unchanged, whether changes are reversible, or that this is a mutation. For a 9-parameter mutation with zero annotation coverage this is a significant under-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?

A single tight sentence with the core action front-loaded and no wasted words. It is efficient, though it trades away richness for brevity.

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

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

A mutation tool with no annotations and no output schema should tell the agent about partial-update semantics, required permissions, and status-transition effects. None of that is present, so an agent cannot confidently predict the consequences of a call from this definition alone.

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%, including a fully documented status enum, so the schema already does the heavy lifting. The description's parenthetical (start, complete, cancel) merely restates what the enum descriptions provide and adds no new syntax or format guidance. 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 (Modify) and resource (scheduled event) plus a secondary action (change its status), which is enough to separate it from create_scheduled_event, delete_scheduled_event, and list_scheduled_events. It stops short of explicitly naming those siblings, so it earns a 4 rather than a 5.

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

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

The wording implies usage (editing an existing event, changing status), but there is no explicit when-to-use, when-not-to-use, or named alternative. For example, it does not tell the agent when to edit vs. delete-and-recreate. Adequate but with clear gaps.

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 burden. It usefully discloses that the action is immediate and terminal for voting ('no further votes can be cast'), but omits whether it is reversible, what happens to existing votes/results, and whether poll-owner permission 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?

A single tight sentence that front-loads the action and its effect. Nothing redundant, nothing wasted.

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

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

For a two-parameter mutation with no annotations and no output schema, the description covers the core action but leaves gaps on permissions, reversibility, and what happens to existing poll results, which an agent would need to invoke it confidently.

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

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

Schema coverage is 100%, so channelId and messageId are already fully documented in the schema. The description adds no additional meaning about identifier formats or constraints, which is the expected baseline when the schema does the work.

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

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

States a specific verb (end/close) and resource (an active poll) with the observable consequence spelled out. It is clearly distinguishable from siblings like create_poll and get_poll_answer_voters without needing 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 word 'active' implies the poll must currently be running, which is a mild precondition, but there is no explicit when-to-use guidance, no statement of what happens if the poll has already ended, and no mention of alternative tools.

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

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

No annotations are provided, so the description carries the full behavioral burden. It implies fuzzy/partial matching but does not disclose whether multiple matches are returned, what happens on ambiguity, or how the default guild fallback behaves.

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 efficient sentence with the search scope front-loaded and zero filler. It is appropriately sized for a two-parameter lookup tool.

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

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

With no annotations and no output schema, the description should carry more weight. It covers the core purpose but omits result shape (single vs. multiple matches) and ambiguity handling, leaving a search tool partially under-specified.

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 (name, guildId) are already documented, including the DISCORD_GUILD_ID default. The description's 'exact or partial' phrasing adds minor meaning about the name parameter's matching behavior, consistent with the baseline 3 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 (find), resource (channel), matching method (exact or partial name) and scope (in a server). It is distinguishable from siblings like get_channel_info or list_channels, though it does not explicitly name those alternatives.

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

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

No guidance on when to prefer this over list_channels or get_channel_info, no prerequisites or exclusions, and no mention that partial matching may return multiple results. The agent must infer usage 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 never states that this is a pure, side-effect-free string formatter (no API calls, no state change), nor what the output looks like. It also omits the 'special_tab' type supported by the schema, so the behavioral surface described is incomplete.

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, and the supported target kinds are listed up front. It is efficient, though it could have used the remaining space to add routing or output-format value.

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 should explain the return value (the generated markdown string) and clarify the inverse relationship with resolve_discord_mentions. It covers the input types adequately but leaves the output and routing unspecified.

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

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

Schema description coverage is 100%, and the enum values for 'type' and 'style' are already fully documented in the schema (including timestamp style meanings). The description adds no syntax or format 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?

States a specific verb ('Generate') and resource ('Discord Markdown mentions and shortcuts') and enumerates the supported target kinds. It is clear on its own, but it does not distinguish itself from the closely related sibling resolve_discord_mentions (the inverse operation) or get_discord_syntax_guide.

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

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

There is no statement of when to use this tool versus alternatives. Given siblings like resolve_discord_mentions, get_discord_symbols, search_discord_symbols, and get_discord_syntax_guide, the agent gets no routing guidance at all, leaving the choice to inference from the name.

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

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

No annotations are provided, so the description carries the full behavioral burden. It conveys that this produces a link (implying no side effects) and that permissions are customizable, but it omits whether generation itself requires elevated permissions, whether the link expires, and that the bot is only actually added after the user completes the OAuth2 flow.

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 the verb, resource, and scope stated immediately and zero filler. Nothing to trim 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 five-parameter, no-annotation tool with no output schema, the description is thin: it never states what is returned (a URL string) or the operational caveats. The 100% schema coverage compensates on parameters, but behavioral context is left sparse.

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 explains guildId, clientId, scopesCsv, permissionsCsv, and permissionsRaw in detail. The description adds the general 'custom permissions' framing but no additional per-parameter meaning, 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 (Generate) and resource (OAuth2 invite link), plus the scope 'to add a bot or application to a server with custom permissions'. This is clear and distinguishable from server-invite siblings, but it never explicitly names the adjacent create_invite tool, so the differentiation is left implicit.

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

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

The description implies the use case (adding a bot/application) but never says when to use this versus create_invite, list_invites, or get_invite_details, and gives no prerequisites or exclusions. The agent must infer which invite tool applies.

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 fails to disclose that audit logs typically require a privileged permission (View Audit Log), that results are paginated/ordered, or what happens when no filters are supplied. 'Fetch' implies read-only but nothing more is confirmed.

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 wasted words; the resource is stated first and qualifiers follow. Efficient, though it is arguably under-specified rather than optimally scoped.

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

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

For a 3-parameter read tool with no output schema and no annotations, the description covers the basics but omits meaningful context: permission requirements for audit logs, pagination behavior, and default ordering. Adequate but with identifiable gaps.

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

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

Schema description coverage is 100%, so the schema already documents all three parameters. The description mentions user and limit filtering but omits guildId entirely and adds no syntax or format detail beyond what the schema provides. 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?

Clear specific verb+resource: 'Fetch server audit log entries'. An agent immediately knows this retrieves audit log data. However, it does not distinguish itself from any sibling or clarify scope (which server, whose logs), leaving minor ambiguity.

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

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

The phrase 'with optional filtering by user and limit' implies the parameters are optional and what they filter, giving some contextual usage. But there is no explicit when-to-use guidance, no prerequisites, and no mention of the alternate tools one might reach for instead.

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. 'Get' implies a read-only operation, but it omits that AutoMod config typically requires elevated permissions (Manage Server / View Audit Log), says nothing about error behavior for an unknown ruleId, and gives no hint about the shape of the returned 'detailed configuration'.

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

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

A single, tightly scoped sentence with the verb and resource front-loaded and zero filler. Nothing is padded or repetitive.

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 tool is simple (one required ID parameter) and reads without side effects, so the description is nearly sufficient. But with no output schema, it should describe what 'detailed configuration' actually returns (triggers, actions, exemptions, enabled state) or note permission requirements; that gap keeps it from being complete.

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

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

Schema description coverage is 100%, so both ruleId and guildId (with its DISCORD_GUILD_ID default) are fully documented in the schema. The description adds no further parameter meaning, so the baseline of 3 applies.

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

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

States a specific verb ('Get') and resource ('AutoModeration rule') with the scope qualifier 'specific', which distinguishes it from list_automod_rules. However, it never names the alternative sibling tools (list/create/edit/delete_automod_rule), so routing relies on the agent's own inference.

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

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

No when-to-use guidance or prerequisites are given. The description does not say to call list_automod_rules first to obtain a ruleId, nor when this is preferable to the list 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?

No annotations are provided, so the description carries the full behavioral burden. It implies a read-only lookup but says nothing about required permissions, behavior when the user is not banned (error vs empty result), or what 'detailed' information is returned — a real gap given there is no 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?

A single, front-loaded sentence with no filler or redundancy. It is appropriately sized, though that brevity is partly why other dimensions are 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 and no output schema, the description is the only source for behavioral and return-value context — yet it never enumerates what ban details are returned or what happens on a non-banned user. For a lookup tool that leans entirely on prose, this is under-specified.

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

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

Schema description coverage is 100%, with both userId and guildId documented in the schema (including the DISCORD_GUILD_ID default for guildId). The description adds no syntax or format meaning beyond that, so the baseline of 3 applies.

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

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

The description states a specific verb ('Get') and resource ('ban information') scoped to 'a specific banned user', which is clearer than a bare name restatement. It does not, however, distinguish itself from the sibling list_bans or explain what 'detailed' encompasses.

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 instead of list_bans (which appears to enumerate bans) or get_member_info/get_user_info. No prerequisites, permissions, or exclusions are 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?

No annotations are provided, so the description must carry behavioral disclosure. Its phrasing 'Get current ... status' implies a read-only, side-effect-free, no-argument call, which is consistent behavior, but it never explicitly states read-only/non-destructive or whether it hits a live API with rate limits. It is adequate but leaves the safety profile to inference.

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. The enumerated outputs earn their place by telling the agent what it will receive. Not a 5 only because it is quite terse and could route the agent better without added bulk.

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 tool with no annotations and no output schema, the description covers what the tool returns and implies a safe read, which is mostly sufficient. However, with no structured safety hints it could do more, and it lacks any guidance distinguishing it from sibling info-getters.

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 are zero parameters, which earns the baseline of 4 under the rubric. The description neither needs nor provides parameter detail, and it correctly implies a self-contained call with no required input.

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

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

States a clear verb+resource: 'Get current bot application status...'. It enumerates exactly what information the tool returns (status, username, ping, server count, uptime), which lets an agent distinguish it from siblings like get_user_info or get_server_info. It stops short of 5 because it does not explicitly name or differentiate from those nearest siblings, which also return identity/status data.

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 or when-not-to-use guidance. The description lists outputs but never states the situation that should trigger this tool versus alternatives such as get_user_info or get_server_info.

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 bears the full burden of behavioral disclosure. It only communicates a read-like operation ('Get') and says nothing about permissions required, rate limits, return behavior, or any other operational trait.

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 zero wasted words. It is appropriately sized for a simple one-parameter read tool.

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

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

For a simple read tool with 100% schema coverage and no annotations, the description is minimally viable but vague. It does not clarify what 'detailed information' includes, and since there is no output schema, an agent cannot know the return contents or scope.

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 parameter channelId is already documented as 'Channel ID'. The description adds no meaning beyond what the schema provides, so the baseline score of 3 applies.

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

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

The description states a clear verb (Get) and resource (detailed information about a specific channel), so the basic action is unambiguous. However, it does not distinguish this tool from siblings like get_forum_channel_info, get_user_info, or list_channels, which an agent might consider for channel-related lookups.

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 alternatives. The description implies it requires a channel ID but offers no context, prerequisites, or exclusions, leaving the agent to infer usage from the name alone.

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

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

With no annotations, the description carries the full burden, and it does convey that output is a curated set of symbols and templates. However, it omits basic behavioral facts such as whether the result is cached/static, whether it is paginated, rate limits, auth requirements, or the return shape, so it is only adequate for a read-style retrieval 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?

It is a single front-loaded sentence with no filler; every noun (symbols, dividers, prefixes, badges, templates) maps to a category or use case, 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?

For a one-parameter read tool with a fully described enum, the description is minimally sufficient, but with no annotations and no output schema it should at least say the result is a static curated list and how it differs from search_discord_symbols.

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 enum parameter already fully documents the allowed categories, including 'all' as default. The description adds no parameter-level meaning beyond listing resource types, so the baseline of 3 applies.

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

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

The description states a specific verb ('Get') and concrete resource types ('aesthetic Discord symbols, dividers, channel prefixes, role badges, and server templates'), and the stated purpose ('building attractive Discord servers') distinguishes it from the sibling search_discord_symbols, which is a search rather than a curated retrieval.

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 purpose implies a design/decoration use case, but the description never states when to use this instead of search_discord_symbols, and no exclusions or prerequisites are given. Usage is only implicitly derivable from 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. It is a zero-parameter, inherently read-only reference, so there is little risk to disclose, but it says nothing about the form of the returned content or its size/length despite being billed as 'comprehensive'.

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; the enumerated topics are the useful content. The list is long but each item adds scope information rather than padding.

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, no-output-schema lookup tool the description is minimally adequate: it tells the agent what topics are covered but not how the guide is returned or how it relates to the other Discord formatting tools it sits beside. Nothing is misleading, but routing information 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?

The tool takes zero parameters, so per the rubric the baseline is 4. There are no inputs whose meaning the description could or should clarify.

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 ('Get') and resource ('reference guide of all Discord Markdown shortcuts, techniques, mentions, timestamps, subtext, spoilers, and internal navigation links'), enumerating the covered topics. It is clear what the tool does, but it doesn't distinguish itself from nearby siblings like get_discord_symbols or format_discord_mention, which could plausibly overlap.

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

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

The description gives no when-to-use context, no prerequisites, and no pointer to alternatives among the many Discord formatting/mention siblings (get_discord_symbols, format_discord_mention, resolve_discord_mentions). An agent must infer that this is the general reference and those are narrower tools.

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

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

No annotations are provided, so the description carries the full burden. It doesn't disclose whether this is a read-only operation, whether it requires elevated permissions, what the response contains, or any rate limits. It only says 'Get details', which is minimal behavioral context.

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, efficient sentence with no wasted words. It's front-loaded with the action and resource. However, it could be slightly more informative without becoming verbose.

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

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

For a tool with no annotations, no output schema, and two parameters, the description is too sparse. It doesn't explain what 'details' are returned, whether authentication is needed, or how to handle the optional guildId. An agent would need to consult external documentation to call this 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 the schema already documents both parameters (emojiId and guildId). The description does not add any meaning beyond what the schema provides, such as format expectations or default behavior. Baseline 3 applies when the schema does the heavy lifting.

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