+name: plan-implementation
+description: Execute an implementation plan end-to-end in the ByteSync repo. Use when the user asks to implement a previously established plan step by step, requires creating a branch before coding, and expects regular commits during progress.
+---
+
+# Plan Implementation
+
+## Overview
+
+Implement a previously agreed plan in ByteSync, one step at a time, while enforcing branch creation and frequent commits.
+
+## Workflow
+
+### 1) Confirm plan scope
+
+Restate the implementation plan in brief. If the plan is not present in the conversation, ask for it before starting.
+
+### 2) Create a branch before implementation
+
+Create a new branch before making any code changes. The branch name must follow ByteSync guidelines:
+
+- Use one prefix only: `feature/`, `fix/`, `refactor/`, `docs/`, or `test/`
+- Avoid extra slashes beyond the prefix
+- Include the issue number if an issue exists (e.g., `feature/1234-add-sync-filter`)
+- Add a short English description
+
+### 3) Implement step by step
+
+Implement the plan in small, ordered steps. After each step:
+
+- Verify the change fits the plan
+- Commit the work with a concise English message
+- Keep commits focused and incremental
+
+### 4) Respect repo conventions
+
+Follow the repo guidance (AGENTS.md), including:
+
+- Do not add unnecessary comments
+- Use FluentAssertions for tests
+- Build and test as separate commands when asked to run them
+
+### 5) Keep the user informed
+
+Provide short progress updates after each step and call out any blockers or missing details before proceeding.
