Plan Crafting

by sentimony · 2K installs

The skill

The plan crafting skill helps coding agents turn an approved design into a detailed implementation plan with bite-sized, test-first tasks, exact files and a self-review before execution.

Only when you ask.

The habit

Approved specs become executable plans.

↻ Runs by itselfspec approved

How the habit works.
You don't have to.

Three questionsWhen does it start? How does it check its work? What does it remember?

01

It starts by itself

spec approved. Runs in Claude Code routine.

  • ↻ spec approved
  • a spec in docs/specs/ is approved

02

It checks its work

plan checks, you choose. If a check fails, it tries again.

  • ✓plan starts with the required header
  • ✓no TBD, TODO or 'similar to Task N' text
  • ✓every requirement maps to a task
  • ✓every helper used in a code block is defined

03

It remembers

plans folder. The next run reads it first: the approved spec and earlier plans for the same area.

docs/plans/

One run, step by step.
Then it stops.

Stop ruleStops after one plan per run; at most 3 automatic review rounds.

  1. 01

    Announce

    Say that plan-crafting is creating the implementation plan.

  2. 02

    Map files

    List files to create or change and what each is responsible for.

  3. 03

    Write tasks

    Write right-sized tasks with Files, Interfaces, test-first steps and commits.

  4. 04

    Self-review

    Check coverage, placeholders, type consistency and symbol closure.

  5. 05

    Cross-review

    If cross-review is installed and a spec exists, run it and apply fixes through review-resolution.

  6. 06

    Ask execution choice

    Save the plan and ask you to pick inline-plan-dev or subagent-plan-dev.

What it may do.
Nothing more.

Safe by defaultIt writes only in its own folder and asks you before anything goes out.

Is it for you?
Use it when it fits.

Quick checkRead both lists. If the left one sounds like you, the Plan Crafting skill helps.

Use it when

  • ✓ A design was approved
  • ✓ You need a multi-step implementation plan
  • ✓ You hand work to subagents

Skip it when

  • – The change is a one-line fix
  • – Requirements are not settled yet

Questions

Plan Crafting skill, answered.

Does the plan include finished code?

For mechanical steps yes; for stateful logic it states behavior and test scenarios instead.

Does it start building?

No. Execution never starts without your explicit choice.

How do I install the Plan Crafting skill?

Copy the prompt at the top into your agent. It installs the skill from sentimony/skills and sets up the habit. Or run npx skills add sentimony/skills --skill plan-crafting.

Is the Plan Crafting skill free?
