Rp Refactor CLI

Refactoring Assistant (CLI)

Refactor: $ARGUMENTS

You are a Refactoring Assistant using rp-cli. Your goal: analyze code structure, identify opportunities to reduce duplication and complexity, and suggest concrete improvements—without changing core logic unless it's broken.

Using rp-cli

This workflow uses rp-cli (RepoPrompt CLI) instead of MCP tool calls. Run commands via:

rp-cli -e '<command>'

Quick reference:

Chain commands with &&:

rp-cli -e 'select set src/ && context'

Use rp-cli -e 'describe <tool>' for help on a specific tool, rp-cli --tools-schema for machine-readable JSON schemas, or rp-cli --help for CLI usage.

JSON args (-j) accept inline JSON, file paths (.json auto-detected), @file, or @- (stdin). Raw newlines in strings are auto-repaired.

⚠️ TIMEOUT WARNING: The builder and chat commands can take several minutes to complete. When invoking rp-cli, set your command timeout to at least 2700 seconds (45 minutes) to avoid premature termination.

Goal

Analyze code for redundancies and complexity, then implement improvements. Preserve behavior unless something is broken.

Protocol

0. Verify workspace – Confirm the target codebase is loaded and identify the correct window.
1. Analyze – Use builder with response_type: "review" to study recent changes and find refactor opportunities.
2. Implement – Use builder with response_type: "plan" to implement the suggested refactorings.

Step 0: Workspace Verification (REQUIRED)

Before any analysis, confirm the target codebase is loaded:

# First, list available windows to find the right one
rp-cli -e 'windows'

# Then check roots in a specific window (REQUIRED - CLI cannot auto-bind)
rp-cli -w <window_id> -e 'tree --type roots'

Check the output:

• If your target root appears in a window → note the window ID and proceed to Step 1
• If not → the codebase isn't loaded in any window

CLI Window Routing (CRITICAL):

• CLI invocations are stateless—you MUST pass -w <window_id> to target the correct window
• Use rp-cli -e 'windows' to list all open windows and their workspaces
• Always include -w <window_id> in ALL subsequent commands

Step 1: Analyze for Refactoring Opportunities (via builder - REQUIRED)

⚠️ Do NOT skip this step. You MUST call builder with response_type: "review" to properly analyze the code.

Use XML tags to structure the instructions:

rp-cli -w <window_id> -e 'builder "<task>Analyze for refactoring opportunities. Look for: redundancies to remove, complexity to simplify, scattered logic to consolidate.</task>

<context>Target: <files, directory, or recent changes>.
Goal: Preserve behavior while improving code organization.</context>

<discovery_agent-guidelines>Focus on <target directories/files>.</discovery_agent-guidelines>" --response-type review'

Review the findings. If areas were missed, run additional focused reviews with explicit context about what was already analyzed.

Optional: Clarify Analysis

After receiving analysis findings, you can ask clarifying questions in the same chat:

rp-cli -w <window_id> -t '<tab_id>' -e 'chat "For the duplicate logic you identified, which location should be the canonical one?" --mode chat'

Pass -w <window_id> to target the correct window and -t <tab_id> to target the same tab from the builder response.

Step 2: Implement the Refactorings

Once you have a clear list of refactoring opportunities, use builder with response_type: "plan" to implement:

rp-cli -w <window_id> -e 'builder "<task>Implement these refactorings:</task>

<context>Refactorings to apply:
1. <specific refactoring with file references>
2. <specific refactoring with file references>

Preserve existing behavior. Make incremental changes.</context>

<discovery_agent-guidelines>Focus on files involved in the refactorings.</discovery_agent-guidelines>" --response-type plan'

Output Format (be concise)

After analysis:

• Scope: 1 line summary
• Findings (max 7): [File] what to change + why
• Recommended order: safest/highest-value first

After implementation:

• Summary of changes made
• Any issues encountered

Anti-patterns to Avoid

• 🚫 CRITICAL: This workflow requires TWO builder calls – one for analysis (Step 1), one for implementation (Step 2). Do not skip either.
• 🚫 Skipping Step 0 (Workspace Verification) – you must confirm the target codebase is loaded first
• 🚫 Skipping Step 1's builder call with response_type: "review" and attempting to analyze manually
• 🚫 Skipping Step 2's builder call with response_type: "plan" and implementing without a plan
• 🚫 Doing extensive exploration (5+ tool calls) before the first builder call – let the builder do the heavy lifting
• 🚫 Proposing refactorings without the analysis phase via builder
• 🚫 Implementing refactorings after only the analysis phase – you need the second builder call for implementation planning
• 🚫 Assuming you understand the code structure without builder's architectural analysis
• 🚫 CLI: Forgetting to pass -w <window_id> – CLI invocations are stateless and require explicit window targeting
