start_task

Record the current git HEAD as a baseline before coding. This snapshot allows later comparison to detect unintended changes and context drift.

Instructions

Lock in the developer's original intent before coding starts. Captures the current git HEAD as a snapshot so later drift is measured from here. Call this the moment a new feature/refactor is requested.

Tool call template

Replace each placeholder with a value matching the input schema. Only required parameters are included; add optional parameters as needed.

  "id": 1,

  "params": {
    "arguments": {
      "task_description": "<task_description>"
    },
    "name": "start_task"

TDQS

A3.9/5.0
Behavior3/5

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

With no annotations, the description must convey behavioral traits. It explains the snapshot mechanism and drift measurement, but omits details on side effects, success/failure responses, or what the tool actually returns. This is adequate but not fully transparent.

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 extremely concise with three sentences, each providing essential information. Purpose is stated upfront, and there is no extraneous content.

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 the simplicity of the tool (single parameter, no annotations, no output schema), the description covers core purpose and usage. However, it lacks information about return values and error handling, leaving some contextual gaps for an AI agent.

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

Parameters3/5

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

Schema coverage is 100% with a clear description for task_description ('verbatim and complete'). The tool description adds no additional semantic value beyond what the schema provides, so a baseline score of 3 is appropriate.

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: 'Lock in the developer's original intent before coding starts.' It specifies a concrete action (capturing git HEAD snapshot) and distinguishes from sibling tool get_intent_diff, which measures drift after starting.

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?

The description provides explicit guidance: 'Call this the moment a new feature/refactor is requested.' It implies the context for use and indirectly contrasts with the sibling tool, but does not explicitly state when not to use.

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