Filesystem Edit Logs

Feature Request (Claude Code and / or Claude Desktop MacOS):

• Filesystem edit logs in .json format
• Track historic edits with context
• Supports version control tracking w/out git
• Filesystem logs can be read later to give successive chats immediate context into historic work
• Additional Product Enhancement for Desktop Claude: Enable MacOS tag operability so any files can be tagged with tags to identify in the Finder UI any files which have been edited by Claude Desktop

I asked Claude to provide me with a sample SOP that I could anchor to future Projects in the App / Web UI and/or point at if using Claude Code when it examines all files w/in a /config directory, and here's what Claude drew up.

I think it's a pretty good first-pass:

Standard Operating Procedure: Claude Filesystem Activity Logging

Purpose and Scope

This document establishes the standard protocol for recording all filesystem operations performed by Claude within the user's environment. The procedure ensures consistent documentation of file creation, modification, and deletion activities for audit, security, and version control purposes.

Log File Location and Structure

Primary Log File

Claude shall maintain a primary activity log at:

/path/to/project/claude_activity_log.json

Secondary Log Files

For files subject to multiple modifications, Claude shall maintain differential logs at:

/path/to/project/logs/differential/{filename}_{timestamp}.json

Log Format Specification

Primary Log Structure

The primary log file shall use the following JSON schema:

{
  "entries": [
    {
      "timestamp": "YYYY-MM-DDThh:mm:ss.sssZ",
      "action": "[CREATE|EDIT|DELETE]",
      "filepath": "/absolute/path/to/file",
      "filesize": 12345,
      "checksum": "sha256-hash-of-file-contents",
      "operation_details": "Human-readable description of operation",
      "conversation_reference": {
        "conversation_id": "MCP-YYYY-MM-DD-NNN",
        "conversation_date": "YYYY-MM-DD",
        "conversation_topic": "Brief topic description",
        "conversation_first_query": "First few words of initial query"
      }
    }
  ]
}

Required Fields

Field	Description	Format/Type	Required
timestamp	UTC timestamp of operation	ISO 8601	Yes
action	Type of operation performed	Enum (CREATE, EDIT, DELETE)	Yes
filepath	Full path to the affected file	String	Yes
filesize	Size of file in bytes	Integer	Yes
checksum	Hash of file contents	SHA-256 string	Yes
operation_details	Description of changes	String	Yes
conversation_reference	Metadata to identify originating conversation	Object	Yes

Additional Fields for EDIT Operations

Field	Description	Format/Type	Required
previous_checksum	Hash of file before changes	SHA-256 string	Yes
new_checksum	Hash of file after changes	SHA-256 string	Yes
changes_summary	Brief summary of changes	String	Yes

Conversation Reference Structure

Field	Description	Format/Type	Required
conversation_id	Unique identifier for referencing the conversation	String	Yes
conversation_date	Date of the conversation	ISO 8601 (YYYY-MM-DD)	Yes
conversation_topic	Brief description of conversation topic	String	Yes
conversation_first_query	First few words of initial query	String	Yes

Differential Log Structure

For text-based files that undergo modification, a differential log shall be maintained with the following structure:

{
  "file": "/absolute/path/to/file",
  "timestamp": "YYYY-MM-DDThh:mm:ss.sssZ",
  "changes": [
    {
      "type": "[addition|deletion|modification]",
      "line_number": 42,
      "content": "Actual text content that was changed"
    }
  ],
  "conversation_reference": {
    "conversation_id": "MCP-YYYY-MM-DD-NNN",
    "conversation_date": "YYYY-MM-DD",
    "conversation_topic": "Brief topic description",
    "conversation_first_query": "First few words of initial query"
  }
}

Implementation Procedures

1. Log Initialization

When Claude first interacts with the filesystem and no log exists:

{
  "entries": [],
  "log_created": "YYYY-MM-DDThh:mm:ss.sssZ",
  "claude_version": "3.7 Sonnet"
}

2. Recording File Creation

When creating a new file, Claude shall:

1. Generate a SHA-256 checksum of the file contents
2. Record the file size
3. Add an entry to the log with action "CREATE"
4. Include conversation reference metadata
5. Provide appropriate operation_details

3. Recording File Modifications

When modifying an existing file, Claude shall:

1. Generate a SHA-256 checksum of the file before modification
2. Make the required changes
3. Generate a new SHA-256 checksum after modification
4. Create a differential log if the file is text-based
5. Add an entry to the main log with action "EDIT"
6. Include both checksums and a changes_summary
7. Include conversation reference metadata

4. Recording File Deletion

When deleting a file, Claude shall:

1. Generate a SHA-256 checksum of the file to be deleted
2. Add an entry to the log with action "DELETE"
3. Include the final checksum and size before deletion
4. Include conversation reference metadata

Examples

Example 1: Creating a New File

{
  "entries": [
    {
      "timestamp": "2024-05-15T14:42:15.326Z",
      "action": "CREATE",
      "filepath": "/path/to/project/instructions.md",
      "filesize": 2451,
      "checksum": "a1b2c3d4e5f6a7b8c9d0e1f2a3b4c5d6e7f8a9b0c1d2e3f4a5b6c7d8e9f0a1",
      "operation_details": "Created new instruction document for MCP file management",
      "conversation_reference": {
        "conversation_id": "MCP-2024-05-15-001",
        "conversation_date": "2024-05-15",
        "conversation_topic": "MCP Implementation",
        "conversation_first_query": "Can you help me set up"
      }
    }
  ]
}

Example 2: Modifying a Configuration File

{
  "timestamp": "2024-05-15T14:45:22.118Z",
  "action": "EDIT",
  "filepath": "/path/to/project/config/config.json",
  "filesize": 758,
  "previous_checksum": "f6e5d4c3b2a1f0e9d8c7b6a5f4e3d2c1b0a9e8d7c6b5a4f3e2d1c0b9a8",
  "new_checksum": "1a2b3c4d5e6f7a8b9c0d1e2f3a4b5c6d7e8f9a0b1c2d3e4f5a6b7c8d9e0",
  "changes_summary": "Added new directory to mount points",
  "operation_details": "Modified configuration to include access to additional folder",
  "conversation_reference": {
    "conversation_id": "MCP-2024-05-15-001",
    "conversation_date": "2024-05-15",
    "conversation_topic": "MCP Implementation",
    "conversation_first_query": "Can you help me set up"
  }
}

Compliance Requirements

1. All Claude instances must adhere to this logging format without exception
2. Logs must be updated before file operations are committed
3. Log entries must be appended in chronological order
4. Fields must be populated with accurate data
5. No log entries shall be modified or removed after creation

This Standard Operating Procedure shall be followed by all Claude instances operating within this environment regardless of conversation history or context.

No repository file, test, or entry point is identified in the issue. Start by locating the filesystem-operation entry points and existing Desktop integration, then define the logging scope, JSON schema, history behavior, and macOS tagging requirements; done means those requirements are implemented and covered by tests.
