Planning System MCP Server

by TAgents

link_intentions

Create dependency edges between tasks to express ordering constraints, such as one task requiring another's output. Prevents cycles and requires both tasks to be in the same plan.

Instructions

Create a dependency edge between two existing tasks. Use to express discovered ordering constraints (e.g., agent realizes task B requires task A's output). Server rejects cycles. Both tasks must be in the same plan.

Behavior3/5

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

No annotations provided, but description discloses cycle rejection and same-plan requirement. Missing return value or side effects beyond creation.

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?

Two sentences, no filler, front-loaded purpose. Every sentence adds value.

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?

Covers purpose and constraints, but lacks return info and parameter details. Adequate given low complexity but missing some context.

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

Parameters2/5

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

Schema coverage is low (25%), but description adds minimal detail beyond schema. 'from_task_id' and 'to_task_id' are not elaborated; 'relation' enum only mentions default; 'rationale' repeats schema description.

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 'Create a dependency edge between two existing tasks' - a specific verb and resource. It distinguishes from sibling 'unlink_intentions'.

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

Usage Guidelines4/5

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

Explicitly says to use for expressing discovered ordering constraints, with examples and constraints like 'Server rejects cycles' and 'Both tasks must be in the same plan.' Lacks explicit when-not.

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