Hive Mind ๐Ÿ

Swarm intelligence for AI agents โ€” collective decision-making through weighted consensus voting.

Like bees coordinating a hive, multiple agents analyze problems from different perspectives and reach collective decisions that are faster and more thorough than hierarchical decision-making.

How It Works

  1. Create a Decision โ€” Post a question for the swarm

  2. Agents Vote โ€” Each agent analyzes from their perspective (financial, legal, technical, market, risk, strategic)

  3. Consensus Emerges โ€” Votes are weighted by confidence and expertise

  4. Decision Made โ€” The collective recommendation with confidence score

expertise_areaNo

TDQS

A3.9/5.0
Behavior3/5

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

No annotations are provided, so the description must fully disclose behavior. It mentions expertise weighting but does not clarify if multiple votes per agent are allowed, if votes can be changed, or if there are side effects. The description partially covers behavioral traits but leaves gaps.

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

Conciseness4/5

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

The description is well-structured with a concise introductory line followed by a clear bulleted parameter list. It is mostly concise, though some phrasing could be tightened. Overall efficient and easy to scan.

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

Completeness3/5

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

Given no output schema, the description could explain return values or confirmation details. It lacks context on limitations (e.g., one vote per decision) and does not describe what happens after voting. It covers parameter semantics well but omits some contextual information.

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

Parameters5/5

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

Schema description coverage is 0%, so the description must compensate. It does so effectively by explaining each parameter: 'decision_id', 'agent_id', 'recommendation' with examples, 'reasoning' length, 'confidence' range, 'perspective' angles, and 'expertise_area' purpose. This adds significant meaning beyond the raw schema.

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

Purpose5/5

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

The description clearly states the tool's purpose: 'Cast a vote on an open decision.' It explains the components of a vote (recommendation, reasoning, confidence) and notes that votes are weighted by expertise. This distinguishes it from sibling tools like 'close_decision' and 'create_decision'.

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

Usage Guidelines3/5

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

The description implies the tool is for voting on open decisions but does not explicitly state when to use it, prerequisites (e.g., decision must be open), or when not to use it. No alternatives or exclusions are mentioned.

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

close_decisionA

Close a decision and record the final outcome.

Locks the decision from further votes and records what was decided.

Args: decision_id: The decision to close final_decision: The final decision taken (optional, uses consensus if empty)

ParametersJSON Schema
NameRequiredDescriptionDefault
decision_idYes
final_decisionNo

TDQS

A4/5.0
Behavior3/5

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

The description discloses that the tool locks the decision from further votes and records the outcome, which are key behavioral traits. However, without annotations, it does not cover permissions, idempotency, or side effects beyond basic locking.

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

Conciseness5/5

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

The description is highly concise, front-loaded with the main purpose, and uses a clear bulleted list for arguments. Every sentence adds value without redundancy.

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

Completeness4/5

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

Given no output schema and no annotations, the description covers the tool's purpose, parameters, and side effect (locking). It lacks details on return value or error handling, but is adequate for a simple mutation.

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

Parameters4/5

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

With 0% schema description coverage, the description adds crucial meaning: decision_id is the decision to close, final_decision is optional and uses consensus if empty. This compensates for the schema gap.

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

Purpose5/5

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

The description clearly states the tool closes a decision and records the final outcome, using specific verbs and resources. It distinguishes from siblings like cast_vote and create_decision by focusing on the closure action.

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

Usage Guidelines3/5

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

The description implies usage when concluding a decision, but lacks explicit when-to-use or when-not-to-use guidance compared to alternatives. The mention of final_decision being optional hints at usage but does not fully specify conditions.

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

create_decisionA

Create a new decision for the swarm to evaluate.

Multiple agents can then vote on this decision from different perspectives (financial, legal, technical, market, risk). The hive mind aggregates votes into a collective decision.

Args: question: The decision question (e.g. "Should we launch product X?") context: Background information for the decision decision_id: Custom ID (auto-generated if empty) created_by: Who initiated the decision

ParametersJSON Schema
NameRequiredDescriptionDefault
questionYes
contextNo
decision_idNo
created_byNo

TDQS

A4.2/5.0
Behavior4/5

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

With no annotations, the description carries full burden. It discloses that after creation, agents can vote and the hive mind aggregates, giving insight into the tool's lifecycle. However, it does not mention side effects, permissions, or reversibility.

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

Conciseness4/5

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

The description is well-structured with a clear purpose statement, a brief process overview, and a formatted Args list. It is slightly verbose in the process paragraph but still concise overall.

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

Completeness4/5

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

The description covers input parameters and high-level behavior. It lacks output specification (no output schema) and does not mention return values, but given it's a creation tool, the description is reasonably complete for an agent to use.

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

Parameters5/5

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

The Args section adds significant meaning beyond the input schema: it explains that question is the decision prompt, context is background, decision_id can be auto-generated, and created_by identifies the initiator. This fully compensates for the 0% schema description coverage.

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

Purpose5/5

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

The description starts with 'Create a new decision for the swarm to evaluate,' which is a specific verb and resource. It clearly distinguishes this from sibling tools like cast_vote or list_decisions by focusing on creation.

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

Usage Guidelines3/5

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

The description implies usage context by mentioning subsequent voting and aggregation, but it does not explicitly state when to use this tool versus alternatives, nor does it provide when-not-to-use guidance.

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

get_agent_expertiseC

Get an agent's expertise profile across all areas.

Shows which areas an agent has voted on and their expertise scores.

Args: agent_id: The agent to look up

ParametersJSON Schema
NameRequiredDescriptionDefault
agent_idYes

TDQS

C2.9/5.0
Behavior3/5

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

The description implies this is a read-only operation by stating it 'shows' data, which is appropriate. However, with no annotations and no detail on side effects, rate limits, or authentication, the transparency is minimal.

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

Conciseness5/5

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

The description is very concise, with only two sentences plus an Args line. Every word adds value, and the structure is front-loaded with the core purpose.

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

Completeness3/5

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

For a simple tool with one required parameter and no output schema, the description is minimally adequate. It explains the return data (areas and scores) but could improve by clarifying what 'expertise scores' represent or any constraints.

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

Parameters1/5

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

The description includes an 'Args' section but provides no explanation of the 'agent_id' parameter beyond its name. With 0% schema description coverage, the agent gains no additional meaning from the text.

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

Purpose4/5

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

The description clearly states the tool retrieves an agent's expertise profile, including areas voted on and scores. However, it does not differentiate from siblings like 'get_consensus' or 'list_decisions', leaving potential confusion about when to use this tool.

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

Usage Guidelines2/5

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

No guidance is provided on when to use this tool versus alternatives. There is no mention of prerequisites, context, or exclusion criteria, leaving the agent without decision support.

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

get_consensusA

Get the current consensus status for a decision.

Aggregates all votes, weights by expertise and confidence, and produces a collective decision with confidence score.

Args: decision_id: The decision to analyze

ParametersJSON Schema
NameRequiredDescriptionDefault
decision_idYes

TDQS

A3.9/5.0
Behavior3/5

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

No annotations exist, so the description must carry transparency. It reveals that it aggregates votes and weights by expertise/confidence, but does not state side effects (read-only inferred from 'get'), idempotency, or required data availability. Moderate transparency.

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

Conciseness5/5

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

The description is two sentences plus an Args line, no wasted words, and front-loaded with the main purpose. Very concise.

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

Completeness3/5

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 should clarify return values. It mentions 'collective decision with confidence score' but lacks detail on the structure (e.g., is it a single number or object?). Also does not mention error cases like missing decision. Somewhat incomplete.

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

Parameters4/5

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

The schema has 0% description coverage, but the description adds 'The decision to analyze' for the single parameter. This provides meaning beyond the schema's title, though it is minimal. Adequate for a simple parameter.

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

Purpose5/5

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

The description clearly states the purpose: 'Get the current consensus status for a decision.' This is specific with a verb and resource, and it differentiates from siblings like cast_vote, close_decision, etc.

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

Usage Guidelines3/5

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

The description does not explicitly state when to use this tool versus alternatives. It implies it aggregates votes, but lacks direct guidance on when not to use it or preconditions (e.g., votes must exist).

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

list_decisionsA

List all decisions in the hive mind.

Args: status: Filter by status ("open", "closed", "all") limit: Max results (default: 20)

ParametersJSON Schema
NameRequiredDescriptionDefault
statusNoall
limitNo

TDQS

A3.5/5.0
Behavior2/5

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

No annotations are provided, so the description carries full burden. It discloses that the tool lists decisions with optional filters, but lacks details on read-only nature, authentication requirements, or pagination behavior.

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

Conciseness5/5

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

Extremely concise: two sentences and arg descriptions with no extraneous content. Front-loaded with purpose, then parameter details.

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

Completeness3/5

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

Adequate for a simple list tool with two optional params and no output schema, but lacks details on ordering, pagination beyond limit, or behavior when status='all'. Could be more complete given zero schema descriptions.

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

Parameters4/5

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

Despite 0% schema description coverage, the description adds meaning by explaining parameter values: status options ('open', 'closed', 'all') and limit as 'Max results (default: 20)'. This clarifies usage beyond the schema's type and defaults.

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

Purpose5/5

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

The description clearly states 'List all decisions in the hive mind', providing a specific verb and resource. It distinguishes from sibling tools like cast_vote and create_decision, which involve different actions.

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

Usage Guidelines2/5

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

No explicit guidance on when to use this tool vs alternatives. The description only defines what it does, leaving the agent to infer usage context from sibling names.

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