How to Configure Global Injection for AI Clients (Claude Code, Cursor, Cline) in reverse-skill

The reverse-skill repository uses a single RULES.md file containing a CRITICAL global-injection block that automatically configures Claude Code, Cursor, Cline, and other AI clients to register the MCP and load the tool index.

The reverse-skill project implements a unified bootstrap architecture where all supported AI code assistants—Claude Code, Code Cursor, Cline, and others—receive identical global injection through a centralized configuration pipeline. This article explains the exact mechanism, file paths, and steps required to enable global injection for any AI client in your reverse-skill deployment.

The Global Injection Architecture

The global injection system in reverse-skill operates as a behavior chain rather than scattered configuration files. Rather than manually editing each client's settings, you trigger a single CRITICAL block that propagates the necessary configuration across all supported platforms.

The chain follows this sequence:

1. README_AI.md → triggers section 0 execution
2. RULES.md → contains the CRITICAL global-injection block
3. Client-specific rules files → auto-generated at known paths
4. MCP registration → enables tool invocation
5. Tool-index refresh → ensures routing validity

Step 1: Trigger the Bootstrap via README_AI.md

AI agents begin by reading README_AI.md at the repository root. This file contains an explicit instruction on lines 5-7: execute section 0 immediately.

According to line 37 of README_AI.md, this bootstrap directs the agent to load RULES.md and locate the CRITICAL block. The file also mandates refreshing the local tool index before proceeding (lines 18-22).

# After cloning reverse-skill, ensure the AI reads this first

cat README_AI.md | head -20

Step 2: Execute the CRITICAL Global-Injection Block in RULES.md

The core configuration lives in RULES.md, specifically at excerpt line 369. This file contains steps 0-14 of the complete behavior chain, but the global-injection block (marked CRITICAL) is what prevents the AI from simply acknowledging the file and stopping.

At line 42, the CRITICAL block performs three essential operations:

Operation	Purpose	Target
Create/append client rules file	Persists configuration across sessions	~/.claude/CLAUDE.md, ~/.cursor/CURSOR.md, ~/.cline/CLINE.md
Register MCP server	Enables real tool invocation	~/.claude/mcp.json and equivalents
Enforce execution	Prevents early termination	Conditional validation

The pseudo-structure of this block (derived from the actual RULES.md implementation) follows this pattern:

# CRITICAL GLOBAL INJECTION — from RULES.md

- client: Claude Code
  config_path: "~/.claude/CLAUDE.md"
  action: create_or_append
  content: |
    # Auto-generated by reverse-skill

    READ RULES.md → EXECUTE CRITICAL BLOCK
    REFRESH TOOL INDEX → /skills/tool-index.md
    REGISTER MCP → ~/.claude/mcp.json

- mcp:
    name: local-mcp
    endpoint: "http://127.0.0.1:8000"
    register_for:
      - Claude Code
      - Cursor
      - Cline

- enforce:
    condition: "RULES.md read"
    then: "EXECUTE GLOBAL INJECTION"
    else: "ERROR – abort"

Step 3: Configure Client-Specific Paths

The global-injection block auto-populates known configuration directories for each supported AI client. According to RULES_zh.md lines 42-44 and docs/PLATFORMS.md line 7, these paths are:

• Claude Code: ~/.claude/CLAUDE.md
• Cursor: ~/.cursor/CURSOR.md
• Cline: ~/.cline/CLINE.md

After the injection runs, verify the files exist:

# Verify Claude Code configuration

ls -la ~/.claude/CLAUDE.md

# Check Cursor rules

cat ~/.cursor/CURSOR.md

# Confirm Cline setup

test -f ~/.cline/CLINE.md && echo "Cline configured"

Step 4: Register the MCP Server

The global-injection step registers the local MCP server—the tool-orchestration layer that allows AI agents to call real security tools directly. This registration is documented in skills/js-reverse/SKILL.md line 34 and skills/ida-reverse/SKILL.md line 339.

The MCP exposes capabilities including:

• Browser automation
• Frida dynamic instrumentation
• IDA Pro integration
• Burp Suite coordination

The registration creates or modifies the client-specific MCP configuration (e.g., ~/.claude/mcp.json) with the local endpoint at http://127.0.0.1:8000.

Step 5: Refresh the Tool Index

Before task routing can function, the client must execute the tool-index refresh script. As specified in README_AI.md lines 18-22, run:

# Navigate to reverse-skill root

cd /path/to/reverse-skill

# Execute the refresh script

./skills/scripts/refresh-tool-index.sh

# Verify output files exist

ls -la skills/tool-index.md skills/tool-index.json

This script populates tool-index.md and tool-index.json, which the global-injection block expects to be present. Without these files, routing will fail.

Step 6: Proceed to Task-Specific Routing

With global injection complete, the AI reads SKILL.md (the skill-specific entry point) and skills/routing.md line 53 to select appropriate methodologies for reverse-engineering, penetration testing, or other security tasks.

This routing is referenced in README_AI.md line 81 as the final step of the initialization chain.

Verification Checklist

Confirm global injection succeeded with this checklist:

• ~/.claude/CLAUDE.md (or equivalent) contains auto-generated header
• MCP configuration file exists with local-mcp endpoint
• skills/tool-index.md and tool-index.json are current
• RULES.md CRITICAL block was executed (not just acknowledged)

Summary

• Single source of truth: RULES.md drives all global injection through its CRITICAL block
• Auto-generation: Client-specific files at ~/.claude/, ~/.cursor/, ~/.cline/ are created automatically
• MCP registration: Enables real tool invocation from any supported AI client
• Tool-index dependency: refresh-tool-index.sh must run before routing functions
• Execution enforcement: The CRITICAL block prevents early termination with conditional validation

Frequently Asked Questions

What happens if the AI client stops after "understanding" RULES.md?

The CRITICAL block contains an enforce condition that triggers an error state if global injection is not executed. According to RULES.md line 369 implementation, the AI must proceed through the entire behavior chain or explicitly abort. Simply acknowledging the file without executing the CRITICAL block violates the protocol.

Can I manually configure global injection without using RULES.md?

Manual configuration is possible but not recommended. The paths ~/.claude/CLAUDE.md, ~/.cursor/CURSOR.md, and ~/.cline/CLINE.md must contain specific routing instructions that reference RULES.md and the MCP endpoint. Missing the conditional enforcement logic or incorrect tool-index paths will cause routing failures.

Why does the MCP endpoint use 127.0.0.1:8000?

The local endpoint http://127.0.0.1:8000 ensures tool execution remains on the host machine for security-sensitive reverse-engineering operations. As implemented in skills/pentest-tools/references/burpsuite-mcp-guide.md, this keeps Frida, IDA, and browser automation on localhost rather than exposing capabilities externally.

Which AI clients beyond Claude, Cursor, and Cline are supported?

The architecture supports any AI client that can read markdown files and execute shell commands. docs/PLATFORMS.md line 7 mentions Windsurf and Kiro as additional supported platforms. The global-injection block adapts to each client's configuration directory structure while maintaining identical behavior chain semantics.
