axodus-task-decomposition（axodus 任务分解）

SKILL: task-decomposition

Purpose

Break a raw task into an ordered, executable, dependency-aware step list with acceptance criteria and explicit open questions.

When to Use

• The request implies multiple files or multiple subsystems.
• The request is vague, inconsistent, or underspecified.
• The request mixes design + implementation + validation.

Inputs

• raw_task_description (required, string): the user request as-is.
• constraints (optional, string[]): non-negotiables (security, time, language, tooling).
• repo_context (optional, string): relevant paths, conventions, or prior decisions.
• risk_level_hint (optional, enum: low|medium|high): if the user already signaled risk.

Steps

1. Restate the task in 1–3 sentences without adding assumptions.
2. Extract deliverables (expected behavior, files to touch, commands to run).
3. Identify unknowns that block execution and convert them into concrete questions.
4. Split work into atomic steps; each step must include:

- action + target - a single primary outcome - acceptance criteria (done_when)

1. Order steps by dependency and mark safe parallelization explicitly.
2. Tag each step with:

- risk (low|medium|high) - validation (what will be checked)

1. If unknowns are material, stop and ask only the minimum questions; otherwise proceed with stated assumptions.

Validation

• No step depends on hidden context.
• Every step has measurable acceptance criteria.
• Dependencies are explicit (no “and then it works”).
• No step contains vague verbs (“improve”, “optimize”, “make better”) without a measurable target.

Output

Structured plan (example schema):

summary: "<what will be delivered>"
open_questions:
  - "<question>"
assumptions:
  - "<assumption (only if low risk)>"
steps:
  - id: 1
    action: "<verb phrase>"
    targets: ["<path/system>"]
    risk: low
    validation: "<check to run>"
    done_when: "<observable condition>"

Safety Rules

• Do not invent requirements, APIs, or file paths.
• If a step can be destructive, require explicit confirmation in the plan.
• Prefer the smallest viable step sequence; avoid gold-plating.

Example

Input:

• raw_task_description: “Add a CLI command to export reports.”
• constraints: ["No breaking changes", "Must include tests"]

Output (excerpt):

summary: "Add `report export` command and tests"
open_questions:
  - "What output formats are required (json/csv/pdf)?"
steps:
  - id: 1
    action: "Locate existing CLI entrypoints and command router"
    targets: ["src/cli/*"]
    risk: low
    validation: "CLI help shows existing commands unchanged"
    done_when: "Command dispatch mechanism is identified"
