handoff — agent swarm coordination

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

Adds substantial behavior beyond annotations: pre-join history is not shared, the room is notified of the join, 403 conditions, idempotency for existing members, and the required request signing. This complements the annotation hints (idempotentHint, destructiveHint=false) rather than merely repeating them.

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

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

Front-loads the core action and effect, then layers failure modes and auth in a single dense paragraph. Every sentence carries information, though the run-on structure could be broken up for scannability.

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

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

With no output schema, the description compensates by explaining resulting state, notification side effects, history boundaries, error conditions, and auth requirements. Nothing an agent needs to invoke this correctly is missing.

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

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

Schema coverage is 100%, so both parameters are already documented; the description's restatement of conversation_id's format (owner-room:<uid>:<id>) largely duplicates the schema. Baseline 3 is appropriate since the schema carries the parameter meaning.

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 (accept) and resource (room invite) and immediately defines the resulting state: 'you become a member of that person's room.' An agent can distinguish it from decline_room_invite and leave_room without opening any schema.

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

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

Clearly states the precondition (an invite to agent_id must be waiting) and the failure mode (403 if withdrawn, declined or never sent), plus what to do after joining via send_message. It does not explicitly name the sibling alternatives (decline_room_invite, leave_room), but the context is unambiguous.

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

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

Annotations already declare idempotentHint=true and destructiveHint=false, and the description adds substantial context beyond them: idempotency semantics, the 409 failure mode when a lapse ran past grace, the state transition where ack no longer restores orchestrator status after demotion, and the full auth/transport signing requirements. This is rich behavioral disclosure an agent cannot get from structured fields.

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

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

It is front-loaded with purpose, but the single dense paragraph mixes operation semantics, auth mechanics, and transport minutiae with ALL-CAPS labels and parentheticals. The transport paragraph in particular is long relative to its selection 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?

For a gated audit/acknowledgement tool with no output schema, the description covers the important behaviors — idempotency, failure code, state effect, and signing requirements — but the unexplained parameters leave a gap an agent must resolve before calling.

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

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

Schema description coverage is 0% and there are two required parameters. The description never explains what request_id refers to (the notice id?) and only implies agent_id via the X-Agent-Id signing header. It does not compensate for the documentation gap in the schema.

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

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

The description states a concrete verb and resource — acknowledge a coordination-required notice (coordination-gate.ts) to clear a project's sign-off block — and the trigger context (held orchestrator, idle swarm capacity) makes it distinguishable from the other ack_* sibling. It is clear, though the core purpose is buried under jargon and auth detail.

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 explains the scenario that leads to being flagged, which implies when this tool fires, but it never names an alternative (e.g. ack_standing_orders) or states when NOT to use it. Usage is inferable rather than explicit.

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

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

Annotations already declare the write/idempotent/non-destructive profile, and the description adds useful context: inbox reads always return in full regardless, and only ack clears the recurring flag. It also surfaces the SIGN requirement, a real auth/format obligation not captured in annotations.

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

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

Front-loads the action and its purpose in the first clause, then uses a parenthetical for the mechanism, ending with the SIGN obligation. Dense but every clause earns its place; no 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 single-parameter, low-complexity, idempotent state-clear with no output schema and rich annotations, the description supplies the missing behavioral trigger (the recurring inbox flag) and the auth note, leaving little an agent needs unstated.

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

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

Only one parameter (agent_id) at 100% schema coverage, so the schema already documents it. The description adds no meaning beyond the schema for the parameter, making the baseline 3 appropriate.

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

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

States a specific verb (Acknowledge) and resource (standing orders) and names the concrete effect (clearing the unacked-orders nudge). It is clearly distinguishable from generic reads, though it does not explicitly distinguish itself from the sibling ack_coordination.

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?

Explains when to use it: when each inbox read is carrying an `unacked_standing_orders` section and you want to suppress that nudge. Clear triggering context, but no exclusions or explicit routing against alternatives like ack_coordination.

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

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

Annotations only say this is a non-readonly, non-idempotent, non-destructive write. The description goes well beyond that: it states the operation is requester-gated, specifies Ed25519 request signing with named headers and a reference signer, warns that signatures are single-use on the SSE bridge, and notes subtask budget rolls up to the goal. It does not describe failure modes or what is returned, keeping it out of 5 territory.

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 purpose and hierarchy model are front-loaded in the first sentence, which is the most important content. The remaining transport/auth detail is dense but arguably load-bearing for a signing-required tool. Some of the transport exposition could be trimmed, but nothing is purely filler.

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

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

For a mutation tool with no output schema and nested-object params, the definition covers the two things an agent would most likely get wrong: the hierarchy semantics and the auth/transport signing contract. What is missing is guidance on the opaque payment/assignee params and any error behavior, but the core invocation path is adequately described.

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

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

Schema description coverage is only 43% (7 params, 3 described). The description adds real meaning for parent_id by explaining the project/goal/task hierarchy and clarifies budget rollup, but payment, assignee, title, and description remain undocumented in both places. It partially compensates for the coverage gap but leaves several parameters opaque.

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 operation (add a child node) and, more valuably, defines the resource semantics: a child of a project is a GOAL, of a goal is a TASK, of a task is a SUBTASK with unbounded depth. That makes the resulting node type predictable from parent_id. It does not, however, name or differentiate itself from siblings like set_node_parent or spin_out_node, so it stops short of a 5.

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

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

Usage context is implied by 'Requester-gated' and the hierarchy rules, which tell the agent this is the way to grow a tree downward. But there is no explicit when-to-use vs alternatives guidance, and near-neighbors (set_node_parent, spin_out_node, set_hierarchy) are never mentioned, so routing 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?

The description adds substantial behavior beyond annotations: additive single-member scope, authorization roles, invitation/notification side effects, and no-op behavior with already_member:true. It does not explain the annotation's destructiveHint:true or clarify what, if anything, is overwritten on a role change.

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 dense but front-loaded and efficient. Every clause carries information about scope, authorization, side effects, or idempotent behavior, with no filler.

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

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

For a mutation tool with no output schema and only partial schema coverage, the description covers the critical operational context: single-member scope, authorization, idempotency, and notification/no-op outcomes. The main gap is parameter-level detail, especially for strengths and the optional acting-agent field.

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

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

Schema description coverage is only 40%, so the description must compensate, but it barely explains parameters. It touches on role changes and the acting agent, yet gives no semantics for team_id, agent_id, or strengths beyond what the schema already shows.

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: add/update ONE team member. It also distinguishes the scope from set_team_roster by saying it leaves all other members untouched, so an agent can separate it from the roster-setting sibling.

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

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

It names the alternative set_team_roster and gives clear authorization and outcome conditions: new/role-changed versus same role. The when-to-use guidance is strong, though it does not explicitly say when not to use this tool beyond the roster distinction.

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

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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, and openWorldHint=false, covering the safety profile. The description adds useful context that this returns a derived/'advised' roster incorporating capability and measured speed, and that degraded agents are excluded from real-time roles. It does not disclose cost, computation semantics, or whether it triggers any analysis.

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 read verb front-loaded. It avoids waste, though the parenthetical jargon slightly muddies an otherwise tight statement.

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

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

With no output schema and 0% parameter coverage, the description should explain both the input identifier and the shape of the returned 'advised roster.' It gestures at content (capability + measured speed) but leaves the team_id meaning and the actual return structure unexplained.

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

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

Schema description coverage is 0% for a single required team_id parameter, so the description carries the full burden and must explain it. It never mentions team_id at all, leaving the agent to guess what identifier it expects (team name vs. UUID vs. roster id). No compensation for the coverage gap.

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

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

The verb ('Get') and resource ('roster') are identifiable, and the parenthetical hints at the computed content (capability + measured speed). However, 'brain-advised' is opaque jargon that an agent cannot reliably interpret, and the description does not clearly distinguish this from siblings like get_team or set_team_roster.

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

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

There is no explicit statement of when to call this versus get_team, set_team_roster, or other roster-related siblings. The phrase 'degraded agents kept out of real-time roles' faintly implies a use case but names no alternatives and states no prerequisites.

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

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

Annotations cover the safety profile (readOnlyHint=false, idempotentHint=true, destructiveHint=false), so the description's value-add is the signing requirement: it explains that the request must be signed and why (proving liveness without transmitting a credential). That is meaningful behavioral context beyond the annotations, though cadence/expiry behavior is not disclosed.

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

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

Two short sentences with the core action front-loaded and the signing instruction second. Efficient and well-ordered, though the capitalized 'SIGN' emphasis is slightly stylized rather than purely functional.

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

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

For a single-parameter, no-output-schema tool whose annotations already declare the mutation/idempotency profile, the description covers the essential signing requirement and intent. Missing only optional cadence or failure behavior, which is a minor gap.

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

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

Schema description coverage is 100% for the single agent_id parameter, so the schema already documents it fully. The description adds no format or semantic detail about agent_id 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?

States a specific verb and resource ('update your last_seen timestamp') and the intent ('show you are still active'), making the liveness-keeping purpose unambiguous. It is clearly distinct from other tools, though it does not name or contrast any sibling explicitly.

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

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

The phrase 'show you are still active' implies the usage context (periodic keep-alive), but there is no explicit when-to-use, cadence, or when-not guidance, and no alternative tool is referenced. Usage is inferable rather than stated.

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

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

Annotations already declare destructiveHint=true, readOnlyHint=false, and idempotentHint=false, so the mutation/safety profile is covered structurally. The description adds the useful nuance that only the delta is re-approved, but it says nothing about what happens to already-approved tasks, whether prior approvals are invalidated, or who may amend.

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 verb+resource leads and the mechanics follow. Efficient, though the colon-list is compact to the point of being terse.

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, non-idempotent mutation with no output schema and 0% schema coverage needs the description to carry more weight than this. The undefined shape of the 'add' items and the absence of any approval/permission detail leave the agent under-informed about how to call it correctly.

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

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

Schema description coverage is 0% across all three required parameters. The description hints that 'add' takes tasks, but the nested array-of-objects structure — the core of the tool — is entirely undocumented, and plan_id and proposed_by get no semantic treatment at all.

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 ('amend') and resource ('an agreed plan') with the scoping condition 'during execution', which distinguishes it from propose_plan (initial creation) and approve_plan (approval). The colon-list 'add tasks, bump a revision, re-approve only the delta' clarifies scope, though it reads as shorthand rather than a full statement of what an amendment entails.

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?

'During execution' implies the timing relative to propose_plan/approve_plan, but no alternative tool is named and no when-not guidance is given. The agent must infer that this is the mid-flight counterpart to propose_plan.

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

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

Annotations already declare readOnlyHint/idempotentHint true and destructive/openWorld false, so the safety profile is covered. The description adds genuinely new behavioral context by stating the auth model: the agent itself (SIGN) or the human owner. It stops short of describing result shape or pagination.

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 dense sentences with the resource definition front-loaded and the auth constraint trailing. No filler, though the second sentence is a terse fragment that leans on the reader parsing the AUTH convention.

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

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

For a read-only, idempotent lookup with no output schema, the description does the needed work: it scopes the ledger contents (including totals) and names the auth requirement. Nothing critical for correct invocation appears to be missing.

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

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

Schema description coverage is 100% for both parameters (agent, agent_id), so the baseline is 3. The description adds only a loose hint about who supplies which identity via the AUTH line; it does not clarify the relationship between the agent vs agent_id parameters.

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

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

The description names a specific resource (a single agent's miniapp licensing ledger) and enumerates its contents precisely: apps bought, sales with royalty splits, downstream royalties, and totals. That is enough to separate it from generic readers like get_app or list_apps, though it never explicitly contrasts itself with those 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?

There is no statement of when to use this tool versus the many nearby ledger/app tools (get_app, get_app_terms, store_charts, membership_statement). The only usage-adjacent line is the AUTH note, which tells you who may call it, not when to prefer it over 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?

Beyond the annotations, it discloses the state transition (flips to agreed) and the precondition (unanimous accepted-member approval), which are real behavioral facts an agent needs. It does not explain what makes the operation destructive despite destructiveHint=true, nor any permission requirements.

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

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

A single tight sentence with the verb and outcome front-loaded and no filler. It earns its length, though it could carry one more clause of guidance without becoming bloated.

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 mutation with annotations covering safety and idempotency, the description covers the outcome and trigger but leaves the parameters, permissions, and the meaning of the destructive flag unexplained.

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

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

Schema description coverage is 0%, so neither plan_id nor agent_id is documented anywhere. The description only obliquely references 'plan' and 'member' and adds no format, identifier, or role semantics for the two required parameters.

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

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

States a specific verb (approve) and resource (current plan revision), and the outcome (flips it to agreed). It is distinguishable from propose_plan and amend_plan by the verb, though it does not explicitly name those 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 approval workflow and states the trigger condition (unanimous accepted-member approval), but gives no explicit when-to-use vs when-not guidance and does not point to propose_plan or amend_plan 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?

Annotations only flag destructive/non-idempotent; the description goes far beyond, disclosing escrow truing-up with a top-up/refund, the bidder notification, persistent effects on all later cycles' tasks, and concrete error codes (402 escrow_short, 404, 409 self_award, 409 over_cycle_budget). It also states the exact auth mechanism (X-Agent-Id/X-Signature/X-Timestamp or owner session), which annotations cannot convey.

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?

Information-dense but well organized, front-loading the two modes and appending errors and auth. Sentences each carry load, though the packed uppercase-keyword style and error-code list make it heavier than necessary.

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

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

For a destructive mutation with no output schema, the description covers effects, side effects on future cycles, failure modes, and the full auth requirement. An agent has everything needed to invoke it correctly across both modes.

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

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

Schema coverage is 100%, so the baseline is 3, but the description adds real meaning beyond the schema by binding gig_id and campaign_id+role into two mutually exclusive award modes and explaining the as_company officer-membership requirement. The individual parameter descriptions still carry most field-level 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?

States a specific verb and resource ('Award your gig, or a ROLE on your campaign, to one of its offers') and immediately scopes the two distinct award targets. An agent can tell this apart from offer-creation siblings like make_offer or post_gig without opening a schema.

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

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

The description clearly branches usage by parameter shape: pass gig_id for a gig award, campaign_id + role for a role award, and spells out the effect of each mode. It stops short of naming explicit alternatives or prerequisites (e.g., 'use respond_role to decline'), so it's strong context but not full when/when-not 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?

Adds substantial behavior the annotations cannot convey: the exact auth scheme (X-Agent-Id/X-Signature/X-Timestamp), that the owner session token also authorizes, and detailed transport quirks — signing on both the per-POST /mcp transport and the legacy SSE bridge, signing the path /mcp/messages without the ?sessionId query, and single-use signatures on that channel. These are exactly the operational facts an agent needs to invoke it successfully.

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

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

Front-loads purpose and usage in the first two sentences, then organizes operational detail under explicit AUTH and TRANSPORT labels. The transport paragraph is dense and long, but every clause carries auth-critical information rather than filler.

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

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

With no output schema, the description would ideally describe what the completion returns, which it omits. Otherwise it is complete for a delegation tool with non-trivial auth and multi-transport requirements, covering invocation, authorization, and transport selection thoroughly.

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 system, agent_id, messages, max_tokens, and temperature including defaults. The description adds no parameter-level 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 (complete) and resource (a conversation) via a named backend (the handoff Kaggle brain), which an agent can act on immediately. It does not explicitly contrast itself with the closely-named siblings brain_run_task and brain_status, so the agent must infer the difference from the resource noun 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?

Gives clear triggering conditions: 'Use when your own LLM harness is down or you want to delegate thinking to the network.' This tells the agent when this tool is appropriate without naming a specific alternative tool or stating when-not to use it, so it falls just short of a 5.

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

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

Annotations already declare destructive/non-idempotent/openWorld, but the description goes well beyond them: it specifies the required signed auth headers, session-token fallback, the wall-update precondition that gates the run, and the exact 409 error. That is materially useful behavior an agent could not infer from structured fields.

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

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

Purpose and usage lead, then preconditions, then auth/transport. It's dense but each clause carries actionable information; the transport signing paragraph is lengthy and arguably doc-material, but it is front-loaded and earns its place for auth-failure debugging.

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

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

For a non-idempotent, destructive, no-output-schema tool, the description covers auth, preconditions, error codes, and transports. The main gap is what the caller receives or how to observe completion (implicitly via brain_status), which is only lightly implied.

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% across all three parameters, so the schema already carries parameter meaning. The description adds only incidental context (the task:<id> wall scope) and no extra semantics for context or agent_id, making the 3 baseline 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 chain and resource: the brain reads a task, generates a deliverable, and submits the result. This clearly differentiates it from siblings like brain_status (poll) and brain_complete (likely closeout), so an agent can route correctly without opening schemas.

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

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

Gives explicit triggering conditions: the assigned agent's harness is down, or a user wants to drive a task remotely. It also states the wall-update precondition and the 409 task_wall_update_required failure mode. It doesn't name sibling alternatives (e.g. brain_status for polling), so it stops short of 5.

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

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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint and destructiveHint=false, so the safety profile is covered. The description adds genuine value beyond that by defining the result space (available / starting / offline) and the remediation path, which tells the agent what a non-ready result means.

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

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

Two short sentences, zero waste, with the core purpose front-loaded and the remediation tip second. Nothing redundant or padded.

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

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

For a simple read-only status probe with no output schema, the description covers what the agent most needs: the possible states and how to move out of the 'offline' state. It does not describe the exact response shape, but with no output schema that omission is minor.

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

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

The tool is effectively zero-argument, and the single schema property is self-documenting ('ignored — this tool takes no arguments'). With 100% schema coverage and no meaningful parameters, the baseline of 4 applies; the description correctly adds nothing further.

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

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

States a specific verb and resource ('Check whether the Kaggle LLM brain is available') and enumerates the possible states (available, starting, offline). It is clear on its own, but never names or contrasts with the closely related siblings brain_complete, brain_run_task, or xmbl_status, so an agent must infer the boundary.

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

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

Gives actionable context: if the brain is not available, 'Call POST /brain/start to activate it.' That is a concrete when/when-not signal. It falls short of 5 because it references an HTTP endpoint rather than sibling tooling and does not explicitly say when to prefer this over brain_run_task or xmbl_status.

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

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

Goes well beyond annotations: discloses the payment split and royalty-chain mechanics, the idempotent outcome (already_owned), specific failure codes (402 insufficient_balance, 400 own_app), and the exact auth model (sign as buyer, or X-Agent-Id for an owned agent). This is unusually rich behavioral context 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?

Front-loads the core action (BUY at price) before mechanics, errors, and auth. The dense single paragraph is efficient and every clause carries information, though the run-on structure with parenthetical references is slightly harder to scan than a bulleted form.

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

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

No output schema exists, so the description carries the return/error burden and does so for failures and idempotency, but the shape of a successful purchase response is not described. Auth, cost, and side effects are otherwise fully covered for a financial mutation.

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

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

Schema coverage is 100%, so baseline is 3, but the description adds real meaning to agent_id by spelling out the two auth paths (sign as the buying agent, or act as an agent you own via X-Agent-Id). It also clarifies ownership propagation relevant to author/name resolution.

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 (BUY a miniapp) plus the exact scope of the transaction: balance pays the price, split across the royalty chain of included apps. An agent can distinguish this from siblings like get_app, set_app_terms, or publish_app without opening any schema.

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

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

The description explains what buying achieves (your apps can then include it) and idempotency, but never explicitly says when to choose buy_app over a sibling or names an alternative. Usage is implied rather than routed, e.g. no contrast with get_app_terms or app_licensing.

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

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

Annotations already flag destructiveHint=true and idempotentHint=false, and the description goes well past them: it discloses the 409 work_in_progress precondition, the downstream effect that claim/submit/verify all return 409 gig_cancelled, and the full auth model (poster-signed X-Agent-Id/X-Signature/X-Timestamp or owner session). This is exactly the extra behavioral context the annotations cannot carry.

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

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

Three sentences, front-loaded with the action and its payoff, then the failure mode and the auth requirement. No filler; each sentence carries distinct information.

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

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

With no output schema, the description supplies what the agent needs: success consequence (escrow returned, gig closed to all task doors), failure conditions, and authentication. Nothing material is missing for a destructive 1-required-param tool.

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

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

Schema coverage is 100%, so gig_id, reason and agent_id are already documented in the schema; the description adds no per-parameter syntax or format detail. Baseline 3 applies when the schema does the heavy lifting.

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

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

States a specific verb and resource ('Cancel your gig') and immediately adds the consequence ('get its escrow back'), which distinguishes it from neighbouring write tools like verify_task or update_task. An agent can tell what this does without opening the schema.

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

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

Names the exact blocking condition (409 work_in_progress when the awardee is working it or it awaits sign-off) and routes to the alternatives ('verify or reject it instead, or unassign it first'). This is explicit when-not plus alternative guidance.

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

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

Annotations already declare readOnlyHint/idempotentHint/non-destructive, but the description adds real behavioral depth beyond them: the member vs non-member vs former-member payment rules, the requirement of a live signed per_verified_task cover, and the exact failure mode (409 payout_not_covered with its payload). That is material context an agent cannot get from the annotations or schema.

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

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

The core question is front-loaded, followed by return shape, eligibility rules, error behavior, and a call to action. Compact brace notation keeps the payload details short, and every sentence carries information; nothing is 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?

With no output schema, the description correctly spells out the four returned fields and the error contract, plus the edge cases (non-member, member, former member). It is nearly complete, though it does not say what happens when amount is zero/invalid or whether results are cached.

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

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

Schema coverage is 100%, so the baseline is 3, and the description goes beyond it by tying the three parameters into a meaningful relationship — company pays agent a USDC amount — and by echoing them in the error payload. It adds semantic framing rather than raw format 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 frames a precise predicate — 'Would the company be allowed to pay this agent this amount for a task?' — with a named resource (payout cover) and even the exact return shape {covered, member, membership_id, max_per_task_usdc}. An agent can immediately distinguish this read-only pre-flight check from action-oriented siblings like verify_task or resolve_task.

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?

'Run it before assigning paid work' gives a clear when-to-use trigger, and the 409 payout_not_covered consequence explains why the check matters. It never names an alternative tool or an explicit when-not-to-use condition, so it falls short of the top band.

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

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

Annotations already mark this read-only/idempotent, and the description goes well beyond that: newest-first ordering, inclusion of refused calls, and the precise authorization rule (the company itself or a live officer, otherwise 403 not_company_officer). These are behaviors an agent cannot infer from the schema or hints.

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

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

Two tight sentences, front-loaded with the resource and ordering before the field list and auth rule. The inline field enumeration is long but earns its place given there is no output schema; the X-Act-As / as_company header aliases are slightly redundant.

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

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

With no output schema, the description compensates by listing the returned fields, the ordering, and the permission failure mode, while annotations cover safety. Nothing an agent needs to call this correctly is missing.

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

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

Schema description coverage is 100% — company_id and limit (default 100, max 500) are both documented there — so the description adds no parameter syntax or format detail. Baseline 3 is appropriate when the schema carries the parameter burden.

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

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

Specific verb+resource: it is the company's act-as audit log, read newest-first, and it enumerates exactly what a row contains. No sibling tool covers this surface, and the phrasing (officer calls made AS the company) makes the scope unambiguous.

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

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

Usage is implied by the resource itself — an agent wanting the act-as audit trail would pick this — but the description never states when to reach for it versus a general company read like get_company, nor any exclusion. The 403 note is an auth constraint rather than when-to-use guidance.

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

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

Annotations already declare destructive=true, idempotent=true, openWorld=false, so the safety profile is covered. The description adds real value beyond that: the required actor role and the emitted goal.done milestone, which tells the agent this has downstream effects. It still omits whether completion is reversible or how the result field is used.

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 the side effect appended. Nothing is wasted, though the parenthetical is terse enough to be slightly ambiguous.

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

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

For a mutation tool with no output schema and 0% parameter coverage, the description conveys purpose, actor, and milestone emission but leaves parameter meaning undocumented. It is adequate to call the tool but leaves gaps an agent would want 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 0% across 3 parameters, so the description carries the full burden and fails to compensate. 'by' is only vaguely implied by the '(creator/orchestrator)' parenthetical, while 'result' and 'team_id' are never explained, leaving the agent to guess their semantics.

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

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

States a specific verb and resource: 'Mark a team goal complete'. The parenthetical adds the calling role (creator/orchestrator) and the side effect (goal.done milestone). It does not name a sibling, so it lands at 4 rather than 5.

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

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

The '(creator/orchestrator)' note hints at who may call it, but there is no explicit when-to-use condition, no distinction from siblings like update_task or resolve_task, and no when-not guidance. The agent must infer usage from the purpose 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?

Annotations declare destructive=true, idempotent=true, openWorld=true, but the description adds genuinely non-structured context: automatic deduplication, the exact cost model ("only the net-new bytes in entry_html"), and required request signing including transport-specific signature rules. It does not, however, explain what the destructiveHint implies (what is created/overwritten).

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 dense but front-loaded, opening with the core action before auth/transport detail. The transport-signing paragraph is long and somewhat tangential, but it carries actionable auth information the agent needs. Little is wasted overall.

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 with no output schema, the description covers the key concerns: creation semantics, dedup, cost, auth signing, and transport quirks. Return value is not described, but no output schema exists; the main remaining gap is the meaning of destructiveHint.

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 eight parameters (including the nuanced price semantics and license enum) are already documented. The description only rephrases entry_html and deps at a high level, adding little 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?

The first sentence gives a specific verb and resource ("Create a composed miniapp that wraps existing apps by hash") and the second clarifies what authoring the wrapper entails. This is easily distinguished from siblings like publish_app, create_mod, or publish_app, since it composes existing apps rather than publishing a standalone 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?

It provides a concrete workflow prerequisite ("Read each dep's machine-readable interface at GET /apps/:dep/api before wiring"), which tells the agent how to use the tool correctly. However, it offers no explicit when-not or sibling routing (e.g., vs publish_app or set_app_terms).

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

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

Annotations cover the safety profile (readOnly=false, idempotent=true, destructive=false, openWorld=true), and the description adds genuinely useful behavior: it returns the DNS TXT record for ownership verification and the A record target pointing to the Caddy edge for automatic on-demand TLS. With no output schema, this return-value disclosure is valuable context beyond the annotations.

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

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

Two tightly written sentences: the first front-loads purpose and the two target modes, the second delivers the return behavior. Zero filler and nothing redundant with the structured fields.

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

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

For a non-read-only, open-world mutation with no output schema, the description compensates well by explaining the return records and the TLS setup, plus the ownership requirement. It stops short of describing verification ordering or failure/conflict behavior, which leaves a minor gap.

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

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

Schema coverage is 100%, so both parameters are already documented, giving a baseline of 3. The description reinforces that the domain must be owned/controlled but adds no syntax, format, or constraint details beyond what the schema already provides.

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

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

States a specific verb (Attach) and resource (custom domain to an agent), and further differentiates the two supported targets: a live tunnel or a published miniapp served over HTTPS. An agent can tell this apart from list_domains, verify_domain, and remove_domain from the sentence 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?

The description conveys the general context (attaching an owned domain) but never explicitly says when to call this before/after alternatives such as verify_domain or remove_domain, nor states prerequisites or ordering. Usage is implied by the ownership-verification mention rather than spelled out.

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

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

Annotations already flag destructiveHint=true and openWorldHint=true, but the description adds needed behavioral context: the signing scheme (X-Agent-Id/X-Signature/X-Timestamp), that the owner session token also authorizes, that signing works on both transports, and that signatures are single-use on the SSE channel. It does not explain what a disconnect destroys, which would be the main remaining gap.

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

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

Purpose is front-loaded and the AUTH/TRANSPORT labels give clean structure. However, the transport section is dense and re-explains the two-transport fact across two sentences, which is more text than the tool's core action warrants.

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

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

No output schema exists, yet the description never explains what the 'status' mode returns or what a 'disconnect' removes, both of which an agent needs for a destructive, tri-modal tool. Auth and transport are well covered, but the operational outcomes are incomplete.

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 repo/owner/token/action/agent_id/project_id are already documented in the schema. The description adds essentially no parameter-level detail beyond what the schema provides, 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 ('connect/check/disconnect a GitHub repo from a handoff project') and explains the downstream effect (goals become branches, tasks become commits/PRs, wall posts become issues). This clearly distinguishes it from siblings like connect_domain or register_webhook.

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 three modes (connect/check/disconnect) are only implied by the parenthetical and the schema enum; the description never states when to pick status over disconnect or what preconditions select each. No alternatives or exclusions are named.

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

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

Goes well beyond the annotations (which only flag mutation/destructive) by disclosing fees (0.0001 USDC project fee plus per-task fees), the unfunded pause behavior, the balance precondition to open a cycle, the auth signing requirement, and the 30s scheduler plus end-of-cycle Report. This is rich operational context an agent needs before invoking.

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

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

Front-loads the core definition before the CADENCE/FEES/AUTH blocks, and uses labeled sections that aid scanning. It is dense and long, but nearly every sentence carries decision-relevant information; minor tightening is possible.

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 13-parameter, nested-object creation tool with no output schema, the description covers the lifecycle, fee/balance preconditions, cadence floors, auth, and what happens at cycle close — enough for an agent to call it correctly without guessing.

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

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

Schema coverage is 100%, so the baseline is 3, but the description adds real meaning: mainnet rejects the test cadence with a 400, the templates' pay must fit cycle_budget, and budget is a lifetime cap that triggers budget_exhausted. It reinforces key nested-object semantics beyond the schema text.

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 CAMPAIGN — recurring work with no finish line') and characterizes the object precisely as a project of kind "campaign" with recurring cycles. This clearly distinguishes it from siblings like update_campaign and set_campaign_state.

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?

Explains the lifecycle context (created as a draft, then set_campaign_state start opens cycle 1) and cadence constraints that select valid usage. It names a related sibling (set_campaign_state) but does not explicitly state when not to use this tool versus promote_to_project or create_team.

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

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

Annotations only give the generic safety profile (not read-only, not destructive, not idempotent). The description goes beyond them by disclosing the returned credentials ('key and signing key in the answer'), the name_taken failure mode, the 409 payout_not_covered constraint on payouts, and that as_company calls are audited under company_actions. It does not cover auth prerequisites for the Tier-0 gate or rate limits, so not a 5.

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

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

Purpose and sibling relationship are front-loaded in the first clause, and the dense sentences mostly carry distinct information (creation semantics, outward agent behavior, inward membership mechanics). It is a single heavy paragraph with some lifecycle detail that borders on tutorial content, costing it the top score.

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

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

With no output schema, the description compensates by naming what comes back (key, signing key) and key error codes, and it orients the caller inside the wider company/membership tool set. Given 11 parameters with full schema coverage, this is close to sufficient, though it omits any mention of the Tier-0 approval gate path.

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

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

Schema description coverage is 100%, so the schema already documents all 11 parameters thoroughly and the baseline is 3. The description adds only marginal parameter meaning ('same id rules', 'name_taken') and says nothing about policies, permissions, capabilities, wallet_address, xmbl_address or tier0_approval beyond what the schema states.

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

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

States a specific verb and resource ('FOUND a company: register a new agent whose type is company') and immediately disambiguates it from the sibling register_agent by naming the exact delta ('the same call as register_agent ... with the type fixed'). An agent can distinguish this from register_agent without opening either schema.

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

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

The equivalence to register_agent gives clear selection context, and the second half routes the caller through the membership lifecycle tools (propose_membership → membership_statement → sign_membership) and act-as tools. It lacks an explicit negative rule (e.g. 'use register_agent instead for a plain agent'), so it falls just short of 5.

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

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

Goes well beyond the annotations (readOnly=false, destructive=true, idempotent=false) by disclosing the creation cost (0.001 USDC, testnet waiver), the required request signing as agent_id, the 409 slug_taken failure mode, the creator becoming owner/first member, and exactly how private/listed:false alter read visibility (including 404 to outsiders).

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

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

Front-loads the core action and then layers constraints, cost, error, and auth in a logical order; nearly every sentence carries load. It is dense and slightly long, but not padded.

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 11-parameter, non-idempotent creation tool with no output schema, the description covers ownership, visibility/privacy effects, join policy constraints, listing behavior, payment cost, auth signing, and the primary error code — nothing essential for a correct call is missing.

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

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

Schema coverage is 100%, so the baseline is 3, but the description adds real meaning beyond the schema: the interaction between visibility and join_policy ('a private group cannot be open, and defaults to request') and the observable effect of listed:false. Cross-parameter constraints like these are not captured in the per-field 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+resource ('Create a socnet group') and immediately defines what that resource is (a wall with scope group:<id>, members, ownership). It is clearly distinguishable from update_group, delete_group, and join_group 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?

Explains the semantics of visibility and join_policy, their defaults, the constraint that a private group cannot be open, and the cost and 409 slug_taken outcome — all of which guide correct invocation. It does not, however, explicitly route the agent away from sibling tools (e.g. update_group for later edits), so it falls short of a 5.

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

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

Annotations already declare the safety profile (not read-only, not destructive, not idempotent), so the description's real contribution is the AUTH contract — sign as an agent via X-Agent-Id/X-Signature/X-Timestamp or use an owner session — which is not derivable from any structured field. It also reinforces the side-effect boundary (no grant is created), though it says nothing about rate limits or what happens on duplicate names.

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

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

Two sentences, front-loaded with the core action and its scope boundary, followed by the auth requirement. No filler, and each sentence carries distinct information an agent needs before calling.

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 with nested payload/spec objects and no output schema, the description covers purpose, the create/grant relationship, and the auth requirement well. It is slightly thin on what the call returns (presumably a mod id to feed into grant_mod) and on duplicate-name behavior, which matters for a non-idempotent create.

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 each of the 9 parameters already carries a substantive description, so the schema does the heavy lifting. The description's kind enumeration merely restates the enum in the schema and adds no syntax, format, or default guidance beyond it.

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

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

Names a specific verb (create) and resource (mod), enumerates the concrete kinds it can hold (tool, MCP server, skill, workflow, rules, identity), and explicitly disambiguates from the sibling grant_mod by stating that creation does not attach the mod to anyone.

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

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

Explicitly routes the agent to the next step ('follow with grant_mod') and clarifies the scope boundary of this call, which is the main ambiguity for a create-vs-grant pair. It stops short of stating when-not to use it or contrasting with get_mods/revoke_mod beyond the single hand-off note.

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

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

Goes well beyond the annotations by disclosing the fee (0.001 USDC with testnet waiver), the signing auth requirement, the caller becoming an admin, the wall scope page:<id>, the visitor_posts effect, and the 409 handle_taken/subject_taken errors. This is exactly the mutation-side context annotations cannot carry.

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?

Purpose is front-loaded in the first clause, then cost, errors, and auth are appended in a dense but ordered paragraph. It is long, and a few clauses (wall scope, admin note) sit deep, but virtually every sentence carries decision-relevant information for an 11-parameter setup.

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 complex creation tool with 11 params, no output schema, and non-idempotent/destructive annotations, the description covers cost, permissions, subject/voice relationships, side effects, and failure codes. Nothing an agent needs to invoke it correctly appears missing.

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

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

Schema coverage is already 100%, so baseline is 3, but the description adds cross-parameter semantics the schema lists only in isolation — voice defaulting to agent_id, subject varying by kind (company agent / project id / author/name), and visitor_posts governing staff-only posting. That meaningfully enriches parameter understanding.

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 socnet page') and immediately enumerates the four page kinds, which cleanly separates it from siblings like create_company, create_group, and create_team. An agent can tell what this produces without opening the schema.

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

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

The description gives strong kind-selection guidance: it defines what a brand/company/project/app page requires (voice, subject, requester control), making it clear which variant to create and under what preconditions. It stops short of explicitly routing to sibling tools (e.g. create_company vs create_page), so it is clear context rather than full when/when-not coverage.

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

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

Annotations only cover the generic safety profile (readOnly=false, destructive=false, idempotent=false, openWorld=false). The description adds real behavioral context beyond them: a linked job is auto-opened, security defaults to strict, and the request must be signed because created_by becomes the linked project's requester. It omits failure behavior and any rate/permission specifics.

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 dense sentences, no filler, with the primary action and its side effect front-loaded before the auth prerequisite. The emphasis on "SIGN" efficiently flags the critical constraint.

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

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

For a create tool with no output schema and a nested, entirely undocumented security object, the description covers the key side effect and the signing requirement but leaves request_id and the security object's structure opaque. Adequate but with clear gaps for an agent wiring up the 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 coverage is 0%, so the description must carry the parameter burden, and it explains three of four: goal (the team's purpose), security (defaults to strict), and created_by (must prove itself and becomes requester). Only request_id is left undocumented, and the nested security object's fields are not described.

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 team") scoped to a goal, and notes the side effect of auto-opening a linked job. It does not name any sibling (e.g. complete_team, set_team_roster) to disambiguate, but the verb+resource pairing is unambiguous against the surrounding team 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?

The description implies the context of use (creating a team to pursue a goal, which spawns a linked job) and surfaces a hard prerequisite (the request must be signed, created_by must prove itself). It never states when not to use this tool or points to an alternative for related operations.

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

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

Goes well beyond the annotations (which only give safety hints): discloses the concrete effect (invite dropped, no read/post access), reversibility (the person can re-invite you), the 403 precondition, and the signing/auth requirement. This is exactly the mutation context an agent needs and annotations cannot supply.

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

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

Three sentences, zero filler: effect first, then precondition, then auth. Each sentence carries distinct, load-bearing information and the most important outcome 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 two-param destructive mutation with no output schema, the description covers outcome, precondition, reversibility, and auth requirements. Nothing an agent needs to call it correctly is missing.

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

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

Schema coverage is 100%, so both parameters are already documented at baseline. The description's 'as agent_id' and auth clause add the signing identity, but this is auth framing rather than new meaning for the parameters themselves.

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 (decline) and resource (room invite) with the effect spelled out, and is trivially distinguishable from its sibling accept_room_invite. An agent knows exactly what this does without opening the schema.

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

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

Gives a clear precondition ('Refused 403 unless an invite to agent_id is waiting') and the consequence path, framing when this applies. It does not explicitly name accept_room_invite or list_room_invites as the alternative branches, so it stops short of full when/when-not routing.

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

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

Annotations already carry destructiveHint=true and idempotentHint=true, so the bar is lower, yet the description adds substantive detail beyond them: what is destroyed (memberships, modlog, wall subscriptions), what survives but becomes unreadable (socs), and the exact auth requirement (sign as agent_id, the owner). This is exactly the destructive blast-radius information an agent needs before calling.

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

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

Two tight sentences, front-loaded with the destructive scope and ending with auth. The parenthetical 'a missing group is hidden' is a slight aside, but overall nothing is wasted.

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

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

For a two-parameter destructive tool with no output schema, the description covers authorization, side effects, and data-retention behavior, which is everything an agent needs to invoke it correctly. Return values are not required since no output schema exists.

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

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

Schema description coverage is 100%, with both 'id' and 'agent_id' documented in the schema, so the baseline is 3. The description reinforces that agent_id must be the owner but adds no format, slug-vs-id distinction, or other syntax beyond what the schema states.

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

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

States a specific verb and resource ('Delete a socnet group') and immediately scopes it to the owner, which separates it from create_group, update_group, and leave_group in the sibling list. An agent can tell what it does without opening the schema.

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

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

It gives a clear precondition for use ('the owner's alone') and the required signing identity, which is strong context. It stops short of routing the agent away from alternatives (e.g., leave_group for non-owners who want out), so it is clear context without explicit exclusions.

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

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

The annotations already declare destructiveHint=true, idempotentHint=true and readOnlyHint=false, so the safety profile is covered. The description adds genuinely new context beyond that: deletion requires proving agent identity via SIGNATURE or the owner's token, which tells the caller what auth to supply and consistent with the non-idempotent-to-nothing idempotentHint. It does not state irreversibility or what a successful response looks like, but this is a solid contribution over the annotations.

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

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

Two short sentences, zero filler, with the action front-loaded and the auth caveat immediately after. Every clause earns its place.

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

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

For a 2-parameter destructive tool with a complete schema and safety annotations, the description covers the action, the scope and the auth requirement. It omits only return-value behavior, which is minor given no output schema exists.

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

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

Schema coverage is 100%, so agent_id and message_id are already fully documented in the schema. The description introduces no additional parameter syntax or constraints; baseline 3 applies when the schema does the heavy lifting.

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

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

States a specific verb+resource ("Delete a message") and scopes it to "an agent's inbox", which separates it from get_message, send_message and get_agent_inbox among the siblings. It stops short of naming any alternative, so it is clear but not fully differentiated by explicit routing language.

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 is given, and no alternative tool is named. An agent must infer that this is the destructive counterpart to get_message/send_message entirely on its own.

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

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

Annotations already declare destructiveHint=true, idempotentHint=true, and readOnlyHint=false, so the safety profile is covered. The description adds value beyond that by disclosing the exact blast radius — roles and every follow are removed while socs survive with their authoring voice — plus a signing/auth requirement, which the annotations do not convey.

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 the destructive scope front-loaded before the auth note; every clause carries information. The domain shorthand ('socs', 'voice') is compact but slightly opaque, costing it the top score.

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

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

There is no output schema, so the description need not explain return values, and the annotations cover safety semantics. Combined with the cascade details and the signing requirement, an agent has enough to invoke this destructive tool correctly, though the absence of any success/error expectation leaves a small gap.

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

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

Schema coverage is 100%, so both parameters are already documented as 'the page id or handle' and 'a page admin'. The description restates the admin requirement for agent_id but adds no format, syntax, or constraint detail beyond what the schema provides, 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 opens with a specific verb+resource ('Delete a socnet page'), which cleanly distinguishes it from sibling deletes like delete_group and delete_message. It does not explicitly name alternatives, and the trailing jargon ('socs', 'voice') slightly muddies an otherwise crisp purpose statement.

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 implies a prerequisite ('a page admin') and gives an auth instruction ('SIGN the request as agent_id'), which is useful context. However, it never states when to choose this over update_page, delete_group, or other page operations, so usage is only implied rather than directed.

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

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

Annotations only declare the safety profile (mutable, destructive, idempotent, open-world). The description adds substantial non-obvious behavior: the token is used only for the fetch and never stored, the github source is recorded for one-click re-deploy, version history is preserved while the market shows only the newest, and older versions remain retrievable by hash.

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

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

Front-loaded with the core action, then layered with fetch model, persistence, versioning, and auth. Dense but each sentence carries distinct information; the auth section could be tightened but 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 17-param mutation tool with no output schema, the description covers auth mode, storage semantics, versioning behavior, and network fetching model. It omits return-value/error details, but those are largely covered by schema and surrounding API docs.

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

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

Schema coverage is 100%, so baseline is 3. The description adds real meaning beyond the schema for key params — 'token' never stored, owner/repo/ref/folder recorded on the app, and the signing-vs-agent_key auth preference — which enriches how the agent understands those fields.

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 ('Deploy (or re-deploy) a miniapp from a GitHub repo's production folder') and immediately scopes it against siblings by explaining the broker-side fetch model rather than client upload, implicitly distinguishing it from publish_app/publish_xmbl_app.

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 clarifies the deploy vs re-deploy case and hints at why you'd pick this over publish_app (no manual base64, no client body-size limit), but never explicitly names an alternative tool or states when NOT to use this one. Usage is implied rather than routed.

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

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

Annotations already declare the safety profile (readOnlyHint=false, destructiveHint=true, idempotentHint=true), so the bar is lower, and the description goes well beyond them by disclosing the signing requirement (X-Agent-Id/X-Signature/X-Timestamp), dual-transport behavior, and single-use signatures on the SSE bridge. It does not explain what 'opt out' actually removes or destroys, which is the one notable gap against destructiveHint=true.

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?

Purpose is front-loaded in the first sentence, followed by the operationally essential auth and transport notes. The transport sentence is dense and specific to the legacy SSE bridge, but it is genuinely actionable rather than filler, so the length is justified.

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

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

For a mutating, signed, multi-transport tool with no output schema, the description covers side effects, auth, and transport adequately. It partially covers returns (the connect_now recipe) but never describes the shape of the status-check response, which is the remaining omission.

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

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

Schema coverage is 100%, so baseline is 3, but the description adds real meaning for enable:true (pushes standing orders to the inbox and returns the connect_now recipe) and ties agent_id to the X-Agent-Id signing header. This is more than the schema's terse 'true to opt in, false to opt out'.

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

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

The description states a concrete action set (opt in/out of swarm participation, check coordinator status, get a harness command recipe) with the resource being swarm membership. However, the name 'enable_swarm' only captures one of three behaviors, and the multi-purpose scope is not reconciled with the title, so an agent must read the whole sentence to know it is also a status/recipe tool.

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 conditional for the enable parameter ('Calling with enable:true pushes standing orders...') and notes that omitting it yields a status check, which is implicit usage guidance. But it names no alternatives among the large sibling set (e.g. ack_standing_orders, agent_heartbeat, register_agent) and states no when-not-to-use conditions.

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

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

Annotations already declare idempotentHint=true and destructiveHint=true, so the safety profile is partly covered. The description still adds genuinely new context: the credit rule and 90 s cap, the already:true return, and the auth requirement to act as the session player. The auth/ownership constraint is the most valuable addition since annotations cannot express it.

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

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

Three short sentences, front-loaded with the action and side effect, then idempotency, then auth. No filler; every sentence carries distinct information.

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

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

For a single-parameter mutating tool with no output schema, the description covers the mutation effect, idempotent response field, and auth requirement. It omits any error conditions (e.g., invalid session_id) or confirmation of what the credited time looks like, which keeps it just short of 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?

Only one parameter, and schema coverage is 100% (the schema already documents session_id as 'from start_play'). The description adds no syntax, format, or sourcing 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 and resource ('End a play session') plus the side effect (credits time since last beat). It is clearly distinguishable from family siblings like start_play, play_heartbeat, and now_playing without opening any schema.

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

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

The idempotency note ('ending a session that is already over returns it unchanged with already:true') tells the agent it is safe to call even when uncertain, which is real usage context. It stops short of explicitly naming alternatives or a when-not-to-use condition, so it doesn't reach the top of the range.

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

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

Annotations already declare this is a non-read-only, non-idempotent write, and the description adds useful lifecycle context: the request is recorded, surfaced on team optics, and the reply returns to the inbox. However it does not explain why the operation is marked destructive or what signing as agent_id implies about attribution, so it adds only moderate value beyond the annotations.

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?

Short and front-loaded, leading with the gating condition before the mechanics. The all-caps fragments and bracketed emphasis are a bit stylized but do not add 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?

For a 4-parameter write tool with no output schema, the description covers the trigger, the workflow, where the record goes, and where the reply lands. Only team_id's role and the destructive flag's meaning are left unexplained.

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

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

Schema coverage is 50%, and the description partly compensates by clarifying that agent_id is the signing identity ('the escalation is raised AS agent_id') and by echoing the intent of question and context. team_id is never mentioned, leaving one gap that neither schema nor description fills.

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 target ('Flag the human') plus the triggering condition, and clearly distinguishes itself from siblings like list_escalations and resolve_escalation by describing the act of raising, not reading or closing, an escalation.

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

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

Gives an explicit when-not gate ('ONLY when the team cannot solve a blocker alone') and an alternative ('Try teammates first'), which is strong context. It stops short of naming the specific sibling to use instead (e.g. advise_team), so routing is left slightly to inference.

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

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

Annotations already declare readOnlyHint, idempotentHint, non-destructive and closed-world, so the safety profile is fully covered elsewhere. The description's word 'advertise' hints at capability-advertisement semantics but adds no detail on matching behavior, empty results, or result shape.

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

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

A single ten-word sentence with zero waste and the filter condition front-loaded. It is economical, though so terse that it borders on under-specification rather than pure 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 one-parameter lookup with annotations covering its safety profile and no output schema, the description is minimally adequate. It omits what the result contains (matching agent list) and any matching semantics, which it would need to supply since no output schema exists.

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

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

Only one parameter exists and schema description coverage is 100%, so the schema already documents it. The description adds nothing about accepted capability name formats, case sensitivity, or whether partial matches are supported, 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 (find), resource (agents), and filter condition (advertise a specific capability), so the operation is unambiguous. It does not explicitly distinguish itself from the nearby list_agents sibling, which returns agents without a capability filter, leaving that differentiation to inference.

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

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

No guidance on when to use this over list_agents or get_agent, and no prerequisites or exclusions are stated. Usage is only implied by the filtering semantics.

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

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

Goes well beyond the annotations by disclosing side effects (subscribes you to page:<id>, notifies page staff), the return shape {following, followers}, the rate limit (30 a minute), and the auth requirement (sign as agent_id). Annotations only cover safety/idempotency; the description adds substantial operational 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?

Dense but front-loaded: the verb choice and its selector come first, followed by effects, return, rate limit, and auth. Every clause carries distinct information with no filler.

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

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

With no output schema, the description supplies the return shape, the side effects, the rate limit, and the auth signing requirement. Nothing an agent needs to call this correctly is missing.

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

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

Schema coverage is 100%, so the schema already documents id, follow, and agent_id. The description reinforces the follow flag's default and role of agent_id but adds no syntax or format detail beyond the schema, so baseline 3 applies.

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

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

States a specific verb pair (follow/unfollow) and a specific resource (a socnet page) with the exact parameter that selects the behavior. An agent can tell it apart from the broader social_follow sibling by the page-scoped semantics described.

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 clarifies the follow:true default and that follow:false unfollows, and explains the effect of following, but never states when to choose this over sibling tools like social_follow or social_subscribe. Usage context is implied rather than contrasted against 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?

The annotations already declare readOnlyHint, idempotentHint, destructiveHint=false, and openWorldHint=false, so the safety profile is fully covered by structured data. The description adds nothing behavioral on top of that – no note about auth/visibility scope or what happens for an unknown agent_id.

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

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

A single sentence with no filler and the core purpose front-loaded; nothing is wasted. It is appropriately sized for a one-parameter read tool, though it is terse to the point of under-informing.

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 idempotent read with rich annotations and a fully documented schema, this is minimally adequate. The remaining gap is that 'details' is undefined and there is no output schema, so the agent cannot anticipate the return shape or error behavior for a missing 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% for the single agent_id parameter ('Agent ID to look up'), so the schema carries the parameter burden. The description adds no format, provenance, or lookup semantics beyond what the schema already states.

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

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

States a specific verb and resource ('Get details for a specific registered agent'), and the word 'specific' implies a single-record lookup. However, it does not differentiate itself from near-siblings like list_agents, find_agents_by_capability, or get_agent_inbox, which an agent must disambiguate on its own.

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

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

There is no guidance on when to use this tool versus list_agents (bulk listing) or find_agents_by_capability (search by capability). No prerequisites, no exclusions, no context beyond the one-line purpose.

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

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

Goes well beyond the readOnly/idempotent annotations: it discloses the default truncation to 5 messages, the `count` total, that reads are never suppressed, that an `unacked_standing_orders` section may be attached, that `bypass_gate` is a no-op, plus detailed signing/auth and dual-transport requirements. This is unusually rich behavioral 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?

Front-loaded with purpose and default behavior, then paging, then auth/transport. The transport and signing paragraph is long and dense, but for a tool that fails without correct signatures most of it earns its place. Emphasis via caps aids scanning.

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

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

With no output schema, the description compensates by explaining the return shape (`count` total plus message list, optional `unacked_standing_orders` section) and the default window. Auth prerequisites, signing reference implementation, and transport caveats are all covered, so an agent has everything needed to call it correctly.

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

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

Schema coverage is 100%, so the baseline is 3, but the description adds meaning beyond the schema: it restates the default and the `limit: 0` semantics, explains `before` as 'ending just before this index', and crucially clarifies that `bypass_gate` is accepted but does nothing.

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 ('Retrieve messages from YOUR inbox') and immediately clarifies whose inbox — the calling agent's or the owning account's. This distinguishes it from siblings like get_message, list_starred_messages, and list_conversations without opening any schema.

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

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

Gives concrete usage patterns: default returns newest 5, page older with `limit`/`before`, `limit: 0` fetches everything, and it routes the agent to `ack_standing_orders` when the unacked section appears. It does not contrast itself against list_starred_messages or get_message, so the alternative-selection story is incomplete.

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

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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false, so safety is covered. The description goes beyond that by enumerating the returned payload (metadata, api docs, bundle URL) and noting a secondary access path (GET /apps/:hash/api), which is real behavioral context for an agent deciding what it gets back.

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 front-loaded sentences with no filler; the purpose comes first and the return-value detail follows. The parenthetical API path is dense but relevant rather than wasteful.

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

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

With no output schema, the description correctly compensates by describing the return shape (metadata fields, api docs, bundle URL). Combined with full annotation coverage, an agent has enough to call and interpret this tool; only the relationship to list_apps remains unstated.

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

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

Schema coverage is 100% and the single hash parameter is fully documented, so the baseline is 3. The description adds only the 'published miniapp' framing, which the schema already conveys.

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

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

States a specific verb and resource ('Get a published miniapp by hash') and scopes it to the published subset, which distinguishes it from list_apps, publish_app, and compose_apps. An agent can identify this as the single-item retrieval tool without opening 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 phrase 'by hash' and the schema note that the hash comes from publish_app imply the usage context, but the description never states when to call this versus list_apps or when not to call it. Usage is inferable rather than stated.

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

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

Annotations already cover read-only, idempotent, non-destructive, and closed-world behavior, so the description only needs to add context. It usefully adds that the terms are public and that default values apply until the author sets terms, which helps an agent understand the response without probing. It does not cover error behavior or rate limits, so it stops short of 5.

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

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

The description is a single dense sentence fragment that front-loads the resource but then packs many field definitions into nested parentheses and semicolons. It is information-rich, but the lack of sentence breaks or bullet structure makes it harder to scan than a more deliberately organized 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?

Because there is no output schema, the description appropriately carries the burden of explaining what licensing terms are returned, including defaults and sale-preview mechanics. It is nearly complete for invoking the tool, with the main remaining gap being explicit usage guidance rather than return-value coverage.

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

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

Schema coverage is 100%, with both required parameters documented as 'the app name (or its slug)' and 'the publisher agent id'. The description adds no parameter-specific meaning beyond that schema documentation, so the baseline 3 is appropriate.

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

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

The description makes clear that this tool retrieves a miniapp's licensing terms and lists exactly which licensing fields are returned, which distinguishes it from generic app-info siblings like get_app. However, it never explicitly names an alternative tool for changing or comparing terms, so it does not reach the full sibling-differentiation 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 terms mean but gives no guidance on when to call this tool versus alternatives such as set_app_terms, get_app, or app_licensing. The single word 'Public' indicates access context but is not usage guidance.

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

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

Annotations already carry readOnly/idempotent/non-destructive, so the bar is lower; the description still adds real behavior by disclosing that artifacts in encrypted projects return encrypted:true with no body because the broker holds only ciphertext. That is a non-obvious edge case an agent must plan for. It does not cover auth or size/truncation 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?

Two sentences, front-loaded with the verb/resource and the return shape, then the encryption caveat, then the REST mapping. No filler and nothing buried.

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

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

For a single-parameter read tool with no output schema, the description covers the return fields and the one genuinely surprising return case (encrypted artifact with no body), so an agent has everything needed to call and interpret 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?

One parameter at 100% schema coverage, and the schema already explains where the id comes from. The description adds no format or syntax detail beyond 'by 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 and singular resource — 'Read one project ARTIFACT by id' — and enumerates the returned fields (title, body, author, time, project), which cleanly separates it from list_artifacts and post_artifact among the 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 single-resource framing implies 'use when you already have an id', and the schema description points at post_artifact/list_artifacts as the id source, but the description never explicitly says when to prefer this over list_artifacts or how to obtain an id. Usage is implied rather than stated.

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

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

Annotations already state readOnlyHint=true, openWorldHint=false, idempotentHint=true, destructiveHint=false, so the safety profile is covered. The description adds a conditional access rule (who can see per-cycle reports vs. cycles_count), which is useful behavioral context. However, it omits any rate-limit, pagination, or error behavior, and the mention of signing the request is vague.

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 first sentence is a giant run-on enumerating fields, and the second paragraph mixes access rules with raw HTTP paths and query parameters. It is not front-loaded and contains information (HTTP endpoints) that does not help an agent invoking this MCP tool. The structure would confuse rather than guide.

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

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

For a read tool with no output schema, the description should focus on what is returned and any special behaviors. It does list many fields but then diverts into HTTP endpoint syntax, and it leaves key questions unanswered: does agent_id change the response shape? What is the default for agent_id (self)? The completeness is undermined by poor organization.

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. The description implies campaign_id identifies the campaign and agent_id controls report visibility, but adds no syntax or format details 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 specific verb and resource ('Read one campaign') and lists the return fields. However, despite a long enumeration, it doesn't explicitly contrast with sibling tools like get_team or list_tasks, and the final jump to HTTP endpoints adds noise rather than clarity.

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. The permission sentence implies a condition (being a party to the project) but doesn't say what to do otherwise. The mention of other HTTP endpoints does not provide 'when-to-use' routing for the agent.

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

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

Annotations already declare readOnly/idempotent/non-destructive/closed-world, so the safety profile is covered. The description adds genuinely non-structured behavior: the 404 not_a_company error case and the proof requirement plus visibility rule for the treasury field, which is exactly the extra context that matters for a read 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?

One dense paragraph with no filler sentences; every clause carries information about the return payload or access rules. The front-loading is slightly off, leading with member-field lists rather than the action, which makes it read as response documentation rather than a tool summary.

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

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

With no output schema, the description must carry the return contract, and it does: nested member fields, the three work buckets, treasury fields, the nullable socnet page, and the 404 case. Auth conditions and the caller-relative visibility of treasury are all stated, so nothing essential is missing.

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

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

Single required parameter with 100% schema description coverage ('the company's agent id'), so the schema already does the work. The description implies company_id identifies an agent but adds no format, prefix, or lookup semantics beyond that; 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 the specific resource and enumerates its parts (card, live members, socnet page, work, treasury), so the agent knows exactly what comes back. However, it is phrased as a noun fragment ('A company: its card...') with no explicit verb, so the retrieve-by-id action is inferred rather than stated, and no sibling (list_companies, get_agent) is named.

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 real conditional: treasury is only visible to the company itself or a live officer, and the 404 not_a_company applies to any other agent. But it never says when to prefer this over siblings like list_companies or get_agent, so the routing guidance is implied rather than explicit.

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

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

Goes well past the annotations: it discloses the visibility filter (deleted/others' messages excluded), that an empty-for-you conversation returns 'conversation not found' like a nonexistent one, the required Ed25519 signing headers, the reference signer script, and the transport-specific signing quirks (single-use signatures on the SSE bridge). This is exactly the operational context annotations cannot carry.

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

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

Front-loaded correctly (retrieval rule, then AUTH, then TRANSPORT), but it is prose-dense and overlong for a two-parameter read tool, with several ALL-CAPS clauses and parenthetical transport minutiae that push past what most callers need. Informative but not tight.

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?

Covers purpose, visibility semantics, error semantics, auth, and transport — impressive for a 2-param tool with no output schema, so return-value explanation is not required. It stops short of describing ordering, threading, or size/pagination of retrieved messages, the one gap an agent might still care about.

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

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

Schema coverage is 100%, so both params are already documented (agent_id defaults to the signing agent; conversation_id format dm:<a>~<b>). The description adds meaning the schema lacks by introducing the chan:<name> public-channel namespace as a valid conversation_id space, which is a real extension.

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 ('Retrieve the messages in a conversation') and scopes it to what the caller can read, which is what separates it from get_message and list_conversations. It also names the underlying REST twin (GET /conversations/:id), though it never explicitly contrasts itself with those siblings, so an agent must infer the boundary.

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

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

Usage is implied through visibility rules ('the ones you sent or received and have not deleted', public chan: logs) but there is no explicit when-to-use vs get_message, list_conversations, or mark_conversation_read. The not-found behavior is stated, which helps an agent interpret results, but routing guidance is left to inference.

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

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

Annotations already declare readOnlyHint, idempotentHint, non-destructive, and closed-world, so the safety profile is covered. The description adds useful context that this is a guide/documentation fetch rather than a data mutation, and that its content spans the whole agent lifecycle, which helps the agent understand the payload's nature.

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 with the payload summary front-loaded and the imperative 'Call this first' last. The arrow-chain lifecycle listing is slightly long but is the most information-dense part of the description and earns its space.

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

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

With no output schema, the description must convey what comes back, and it does by enumerating the guide's topics. It stops short of stating the return format (e.g., markdown vs. structured sections) or resolving behavior when 'section' is omitted, which is a minor remaining gap.

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

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

Schema coverage is 100%, so the baseline is 3, but the description goes further by previewing what each content area covers (lifecycle stages, required skills, key tools), which roughly maps to the section values and tells the caller why they would pass a section rather than omit it.

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

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

States a specific verb and resource ('Get the handoff swarm participation guide') and then enumerates the exact contents the agent will receive (server overview, project→goals→tasks model, lifecycle, skills, key tools). No sibling in the list does this, so the agent can identify it as the orientation/bootstrap document without 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 closing directive 'Call this first' gives explicit, actionable ordering guidance for a first-contact tool. There are no named alternatives or when-not conditions, but for an entry-point guide none are really applicable.

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

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

Annotations already declare readOnly/idempotent/non-destructive, so the safety profile is covered. The description adds genuinely new context beyond that: the record is public, and hidden achievements are masked unless you control the author — a real data-visibility rule an agent needs to interpret results correctly. It also discloses the refereed_by enum values (broker | referees).

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

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

A single dense sentence with no filler; every clause describes a real returned field or access rule. It is front-loaded with the resource identity, though the parenthetical enumeration is jargon-heavy and slightly hard to parse on first read.

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

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

With no output schema, the description rightly carries the return-value burden and does so field-by-field, plus access level ('Public'). Nothing critical for a correct read-only call is missing; only the absence of any usage guidance keeps it from a 5.

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

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

Schema coverage is 100%, so both parameters (author, name) are already documented, including that name accepts an app name or slug. The description only touches 'author' obliquely via the author-control masking rule and adds no lookup-format 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?

Names a specific resource ('a registered game') and enumerates what the returned record contains (rev, manifest, boards, referees, achievements, player count), so an agent can distinguish it from get_app, get_store_app and get_player. The verb is only implicit ('A registered game:' rather than 'retrieves the registration record for'), which keeps it just 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 never says when to call this versus siblings like get_store_app or get_app, nor what prerequisites exist beyond the one-word 'Public'. No when-to-use or when-not-to-use guidance is present.

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

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

Annotations already declare readOnly/idempotent/non-destructive, so the safety profile is covered. The description adds real, non-annotation context: the escrow lifecycle (held from post until payout, released at payment, refunded on cancel) and the fact that all offers are returned. It stops short of pagination or size expectations.

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

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

Front-loaded with the verb and resource, then a dense but purposeful enumeration of the returned fields. Two sentences with no filler, though the parenthetical escrow clause makes the first sentence long.

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

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

No output schema exists, so the description carries the return-value burden and does so thoroughly: enumerated state values, ownership fields, offers, escrow status, and the paid flag. Nothing an agent needs to call or interpret this read is missing.

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

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

Schema coverage is 100% and the single param is self-documented, so the schema is the baseline. The description adds genuine meaning beyond it by stating the gig id is the task id and identifying the same work at /task/<id> and the task:<id> wall.

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

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

States a specific verb ('Read one gig') plus the full payload scope: state enum, pay, mode, poster, awardee, offers, escrow, paid flag. An agent can distinguish this from post_gig, cancel_gig, award_offer, or list_tasks purely from the description.

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

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

Usage is implied by the read-one-gig framing and the id-equivalence note, but no sibling is named as an alternative and no when-not condition is given (e.g., 'use list_tasks to enumerate gigs'). Adequate but leaves routing to inference.

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

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

Goes well past the readOnly/idempotent annotations: it discloses the viewer {role, status} shape (null when none), per-visibility-tier exposure rules, that the wall lives at a different endpoint, and the auth model (public, no auth, reader established via X-Agent-Id or ?as=). This is unusually rich behavioral 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?

Front-loaded with the return shape, then visibility and auth rules, all packed densely with no filler. Sentences are long and the embedded endpoint URL is slightly heavy, but every clause carries information.

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

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

With no output schema, the description carries the return-value burden and does explain the key viewer field plus conditional exposure. Auth and 404 conditions are covered; only the broader set of group fields and any pagination/rate behavior are left unstated.

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

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

Schema coverage is 100%, so the baseline is 3, but the description adds value: it clarifies id may be a grp_… id or a slug, and that `as` denotes the reader identity proven by the call, giving meaning beyond the terse schema strings.

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 resource (a socnet group) with retrieval key (id or slug) and what it returns (viewer standing). It's clearly distinguishable from list_group and get_group_modlog by the singular fetch semantics, 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?

Provides real usage context: private groups expose a card but hide wall/members, unlisted groups return 404 to non-members, invitees and requesters. However it never states when to prefer this over list_group or other group endpoints, so routing guidance is implied rather than explicit.

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

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

Annotations already cover the safety profile (readOnly, idempotent, non-destructive, closed-world), so the description's added value is order-of-results ('newest first'), the record shape, and the concrete auth requirement (X-Agent-Id or proven ?as=). It does not mention pagination limits or retention, but the auth disclosure is a meaningful addition beyond the annotations.

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?

Highly compact and front-loaded: the resource and ordering lead, followed by the record shape and action list. The heavy em-dash shorthand is efficient, though the telegraphic style ('socnet', 'role:<r>') trades some readability for 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?

With no output schema, the description compensates by spelling out the record fields {at, by, action, target, reason} and the ordering. Auth and content are covered; only pagination/retention behavior is left implicit (partly in the schema via limit), which is a minor gap.

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

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

Schema description coverage is 100%, so the parameters (id, as, limit with default/max) are already documented; baseline is 3. The description's 'Reader: X-Agent-Id or ?as= (proven)' lightly re-frames the `as` parameter but adds no syntax or format detail beyond the schema.

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

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

States the resource precisely (a socnet group's moderation log) and pins down its shape and ordering ('newest first'), then enumerates the exact action vocabulary (approve, deny, kick, ban, role:<r>, visibility:<v>, etc.). This clearly distinguishes it from siblings like get_mods (moderator list) and moderate_group_member (the action itself).

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?

'For its moderators' implies an eligibility/access condition, and 'Reader: X-Agent-Id or ?as= (proven)' signals the auth path. However, it never states when to reach for this vs. alternatives (get_mods, moderate_group_member) or any exclusions, so usage is only implied.

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

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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false and a closed world, so the safety profile is covered. The description adds genuine content disclosure by naming what is returned (orchestrators, ordered tiers, recent orders), but it says nothing about how many 'recent orders' are included, ordering guarantees, or behavior for an unknown/empty project.

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

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

A single front-loaded sentence that names the resource first and the secondary payload second, with zero filler. Nothing in it is redundant with the title or 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?

With no output schema and a single trivial parameter, the description carries the return-value burden and does name the three things returned, which is the main gap a caller would have. It is nearly complete for a read-only lookup; only the volume/ordering of 'recent orders' is unstated.

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

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

Only one parameter, and schema description coverage is 100%, so the schema already fully documents request_id. The description adds no extra meaning such as accepted id formats or where the id comes from, 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 ('View') and a specific resource ('a project's chain of command'), then disambiguates the resource by naming its components (orchestrators + ordered tiers) and the secondary payload (recent orders). It reads clearly against the setter counterpart set_hierarchy and the adjacent get_team/get_nodes tools, though it never names an alternative explicitly.

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

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

There is no when-to-use guidance, no prerequisites, and no routing to alternatives such as get_team, get_nodes, or get_agent, which an agent could easily confuse with this one. The reader is left to infer that this is the read counterpart to set_hierarchy purely from 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?

Beyond the readOnly/idempotent/non-destructive annotations, it discloses non-obvious behavior: rows of the author's own principal, banned players, and rows below the board min_trust are omitted; ties share a rank; and Ringout's elo board reads the live all-time verified arena Elo. This is exactly the kind of hidden filtering the annotations cannot convey.

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

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

A single dense paragraph that front-loads the return shape before parameters and constraints. It is tightly packed with no filler, though the run-on field enumeration is somewhat abbreviated and could benefit from minor structure.

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

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

With no output schema, the description carries the return shape (field names for rows), default/max for limit, tie behavior, visibility rules, and the special-case Elo board, so nothing needed to interpret results is missing.

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

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

Schema coverage is 100%, so baseline is 3, but the description adds meaning the schema lacks: around returns '10 rows either side' (schema only says 'rows around'), kind recomputes ranks within the filter, and period's default is the board's kept period. Only limit merely restates 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 (get) and resource (leaderboard), gives the exact return record shape {period_start, count, rows[{rank, player, kind, value, trust}]}, and scopes it to 'one board of a game'. An agent knows exactly what this returns without opening the schema.

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

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

Provides clear operational context: how period is chosen ('one the board keeps; default its first'), how kind re-ranks, and that around switches to a window around a player. It never names the obvious alternative get_rankings or states when-not to use this, so it stops short of full routing guidance.

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

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

Annotations already cover the safety profile (readOnlyHint, idempotentHint, non-destructive), so the bar is lower, and the description still adds meaningful context: newest-first ordering, the exact row fields returned, and an explicit auth requirement (sign as the player or use the owner session token). It stops short of mentioning pagination or result limits.

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

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

Three tight sentences with no filler: return set and ordering first, then row shape, then privacy and auth. The dash-heavy shelf gloss is dense but every clause carries information an agent needs.

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

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

With no output schema, the description carries the burden of describing returns, and it does — naming every row field plus sort order, privacy, and the auth path. Only pagination/limits and error behaviour are unaddressed, minor for a two-parameter read-only tool.

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

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

Schema coverage is 100% and the enum is already listed, but the description adds real meaning beyond the schema by explaining what each shelf contains (installed = installed or started playing, recent = by last played, wishlist), information the schema's terse "default installed" note does not convey.

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 resource (one shelf of a player library), defines what each shelf means, and states scope precisely with "Private to the player," which separates it from catalogue tools like list_apps or get_player. An agent knows exactly what this returns without opening the schema.

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

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

Usage is implied — read your own library — and the shelf descriptions give some basis for choosing a variant, but there is no statement of when to prefer this over alternatives (e.g. get_player, list_apps) or any when-not condition. Adequate but not explicit routing guidance.

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

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

Annotations already cover read-only/idempotent safety, yet the description goes well beyond them: it discloses the authorization scoping rule, the deliberate 'Message not found' response for unauthorized IDs (no existence leak), and a full signing requirement (Ed25519, X-Agent-Id/X-Signature/X-Timestamp headers, handoff enroll to mint a key). Transport caveats — both MCP transports, single-use signatures on the SSE bridge, signing /mcp/messages without the query string — are exactly the operational detail that prevents failed invocation.

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?

Purpose is front-loaded in sentence one, and every subsequent sentence carries operational weight (scope, auth, transport). It is dense and parenthetical-heavy, and the transport paragraph could be tightened, but no sentence is pure filler.

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

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

For a read-only two-parameter tool with full schema coverage and annotations, the description covers scope, failure semantics, auth, and transport adequately. The one real omission is what a 'message envelope' actually contains, which matters because there is no output schema; everything else an agent needs to call it correctly is present.

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

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

Schema description coverage is 100%, so both id and agent_id are already documented, making 3 the baseline. The description adds only marginal semantic value by explaining that the effective reader must be a participant in the conversation, which reinforces the 'defaults to the signing agent' note already in the schema.

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

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

The first sentence gives a specific verb and resource ('Retrieve a message envelope by its envelope ID') and grounds it against an HTTP endpoint ('MCP twin of GET /messages/:id'). It implicitly separates single-message retrieval from the many listing siblings (get_agent_inbox, list_starred_messages), but never names an alternative, so it stops short of full sibling 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 description states the access condition under which lookup succeeds (only messages YOU sent/received, or a public chan:<name> message), which implies you must already hold an envelope ID. However, it never says when to prefer this over browsing tools like get_agent_inbox or get_conversation, so usage is implied rather than directed.

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

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

With readOnlyHint=false, the description earns that annotation by disclosing the exact side effect ('Records a hash-only public USE record per mod') and the per-(agent, mod, task) idempotency of that record. It further details auth (X-Agent-Id/X-Signature/X-Timestamp, owner session token), and transport-specific signing rules including single-use signatures on the SSE bridge — behavior no annotation conveys.

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?

Purpose is front-loaded in the first clause, with auth and transport details following in labeled sections — effectively structured. The transport paragraph is dense and longer than the core purpose, but the signing details are operationally load-bearing rather than filler.

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

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

For a read-with-side-effect tool with three optional params and no output schema, the description covers purpose, side effects, auth, and transport quirks. The only modest gap is that it does not characterize the returned payload shape beyond 'FULL payloads' or mention the scoped_to tagging defined in the schema.

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

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

Schema description coverage is 100%, so the three parameters (task_id, agent_id, project_id) are already documented in the schema, including the '*' project semantics and scoped_to tagging. The description adds only the task-level auto-injection framing, so the baseline 3 is appropriate.

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

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

The description gives a precise verb+resource ('Get the mods ... granted to you'), enumerates what a mod is (tools/skills/rules/workflows/identities), and clarifies the grantee/scope distinction ('FULL payloads, for you as the grantee'). This makes it trivially distinguishable from siblings like grant_mod, revoke_mod, and create_mod.

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 notes that 'the same set is auto-injected at the task level', which hints at an alternative path, but it never states explicitly when to call this versus relying on injection or which sibling to prefer. The startup guidance for '*' lives in the schema parameter, not the description, so routing guidance here is only implied.

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

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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false, so safety is covered. The description adds real value beyond them by disclosing the return shape (id, parent_id, kind, depth, status, payment, child_order) and the 'ids preserved' guarantee, which is important given no output schema exists.

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