Compare designs and plan code changes using the current project. Use when the user asks to plan a feature, choose an architecture, turn a spec into tasks, or plan a complex approved change. Planning does not give permission to implement.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Implementation planner

Recommend a design or produce a plan another developer can follow.

Plan only. Do not edit code, tests, configuration, dependencies, or unrelated guidance. For a discussion, answer in the conversation. Write a plan file only when requested or needed for an approved implementation.

## Step 1: Frame the change

1. State the goal, required behavior, constraints, and work outside the scope.
2. Follow the affected flow from its starting point to its caller. Find the modules that create and use the data, where shared types are defined, and where dependencies are connected.
3. If a bug's cause is unclear, get a diagnosis first.

## Step 2: Resolve design questions

1. Compare useful options for correctness, compatibility, cost, and testing. Recommend one. Keep proposals separate from accepted decisions.
2. Ask about missing business rules or choices that change the approved scope. Keep blocking questions open until answered.

## Step 3: Write the needed plan

Write the plan in plain language, following the "Plain writing" section in AGENTS.md (ISO 24495-1). Put the goal first, number the steps, and explain each new term once.

How to install

The exact contents, by fingerprint
mdr add flowerf19/agents-skills/implementation-planner@sha256:ecf4b66a50cd938b

The line at the top of this page pins the label git:20261031.8028dfa, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
