CLAUDE.md Optimization: Fix Verbose Agent Plans with Concise Configuration Guide [2026]

What you'll learn in this article

Specific configuration methods to make Claude Code's plan outputs concise How to write CLAUDE.md files that generate actionable plans Best practices for team operations

Are you struggling with Claude Code's plan mode being too verbose and unclear about concrete actions? This article explains how to optimize CLAUDE.md files to make Claude Code generate concise, actionable plans with clear follow-up questions.

Target Audience

  • Intermediate developers frustrated with Claude Code's verbose outputs
  • Development team leaders wanting to standardize Claude Code behavior
  • Engineers seeking to build more efficient AI development workflows

5-minute outcomes

  1. Reduce verbosity: Shorten plan length by 50-70% for improved readability
  2. Enhance actionability: Clarify specific action steps
  3. Improve development efficiency: Speed up next actions through follow-up questions

Root cause: Why Claude Code becomes verbose

Claude Code generates lengthy outputs in plan mode for these main reasons:

Typical verbose patterns

// Bad example: Verbose plan output
## Implementation Plan

### Phase 1: Requirements Analysis and Design
In this phase, we will thoroughly analyze the project requirements and design the architecture.
Specifically, we will perform the following tasks...

### Phase 2: Basic Implementation
We will implement basic functionality. In this phase...

Problems: - Unclear specific file names and commands - Ambiguous next actions - Takes too long to read through

Solution: CLAUDE.md Optimization Template

Step 1: Basic configuration to enforce conciseness

Place the following CLAUDE.md in your project root:

# Project Control Configuration

## Output Constraints (Mandatory)
- **Plan output**: Maximum 200 words
- **Heading hierarchy**: Up to h3 only (h4+ prohibited)
- **Specificity focus**: Include file names, commands, line numbers
- **Next action**: End with 1-3 specific questions

## Plan Structure Template

Implementation Plan

Files to Change

  • src/components/Button.tsx (create new)
  • src/styles/globals.css (modify L45-60)

Commands to Run

npm install tailwindcss
npm run dev

Verification Points

  1. Does the button hover effect work as expected?
  2. Is responsive design needed?
  3. Should we add test cases? 
    ## Response Style
- No verbose explanations
- Prohibit abstract expressions like "detailed analysis", "comprehensive review"
- Code examples limited to 10 lines maximum

Step 2: Configuration to enforce specific actions

# Execution Constraints

## Required Format
All suggestions must follow this format:

**What**: [Specific file or command]
**Where**: [File path:line number]
**Why**: [Reason within 20 characters]

## Prohibited Expressions
- "needs to be considered"
- "perform detailed analysis"
- "comprehensive approach"
- "considering various factors"

## Required Elements
- Specify next command to execute
- Describe verification method in one line
- Present 1-2 follow-up questions

Step 3: Team operation rules for sharing

# Team Operation Rules

## Claude Code Usage Constraints
- Plan outputs must be readable within 3 minutes
- Implementation should start within 5 minutes
- Unclear points should be resolved with maximum 3 questions

## Output Quality Check
Each output must satisfy:
- [ ] Contains specific file paths
- [ ] Contains executable commands
- [ ] Next actions are clear
- [ ] Review time under 3 minutes

Common troubles and solutions

SymptomCauseSolution
Output still too longVague constraintsUse numerical limits like "maximum 200 words"
Continues with abstract suggestionsLack of specificity instructionMandate file names and line numbers

Advanced optimization settings (for experts - click to expand) ### Project-specific customization 
# Project-Specific Constraints

## Frontend Development
- Always include build verification commands for CSS changes
- Consider Storybook files when creating components
- Mandate eslint error checks for type definition changes

## Backend Development
- Always include OpenAPI definition updates for API changes
- Specify migration file creation for database changes
- Mandate test case additions

Implementation results comparison

Before (pre-optimization)

## Implementation Plan

In frontend development, improving the user interface is...
(500+ lines of detailed explanations)

After (post-optimization)

## Implementation Plan

### Files to Change
- `src/Button.tsx` (new)
- `tailwind.config.js` (add L12)

### Execute
```bash
npx create-component Button
npm run dev

Verification Points

  1. Does hover effect work as expected?
  2. Is mobile support needed? ```

Improvement results: - Reading time: 5 minutes → 30 seconds (90% reduction) - Implementation start time: 15 minutes → 2 minutes (87% reduction) - Issue resolution: Average 3 questions → 1 confirmation
