PostToolUse hook errors occurring during tool execution

Problem Statement

The claude-mem plugin is throwing multiple PostToolUse hook errors when tools like Edit, TodoWrite, and Read are executed. These errors appear to be occurring consistently across different tool operations, potentially preventing proper memory persistence or observation recording.

Environment

• Claude-mem: 9.0.1
• Claude Code: 2.1.1 (Claude Code)
• Node.js: v24.3.0
• Bun: 1.3.5
• OS: macOS 15.3 (arm64)
• Platform: darwin

Configuration

• CLAUDE_MEM_MODEL: claude-sonnet-4-5
• CLAUDE_MEM_WORKER_PORT: 37777
• CLAUDE_MEM_WORKER_HOST: 127.0.0.1
• CLAUDE_MEM_LOG_LEVEL: INFO
• CLAUDE_MEM_CONTEXT_OBSERVATIONS: 50

Worker Status

• Running: Yes
• PID: 58095
• Port: 37777
• Uptime: 217 minutes
• Active Sessions: 0
• SSE Clients: 8

Database

• Path: ~/.claude-mem/claude-mem.db
• Exists: Yes
• Size: 4.00 KB

Observed Behavior

When tools are executed in Claude Code, PostToolUse hooks are failing with errors. The following hooks are affected:

• PostToolUse:Edit hook
• PostToolUse:TodoWrite hook
• PostToolUse:Read hook

Each hook error appears to be reported twice in the logs, suggesting the error may be occurring at multiple stages or being logged redundantly.

Expected Behavior

PostToolUse hooks should execute successfully without errors, allowing claude-mem to properly:

• Observe and record tool usage
• Persist relevant context to memory
• Update the database with new observations

Additional Context

• The worker appears to be running normally (uptime 217 minutes)
• Database exists but is relatively small (4.00 KB), which may indicate data isn't being written successfully
• There are 8 SSE clients connected but 0 active sessions
• The errors occur consistently across multiple tool types (Edit, TodoWrite, Read)

[github-actions]

This GitHub issue reports recurring errors with the PostToolUse hooks during the execution of tools (Edit, TodoWrite, Read) in the claude-mem plugin (version 9.0.1) integrated with Claude Code (version 2.1.1). The errors are logged twice per tool operation, suggesting either repeated failures at multiple stages or redundant logging. These errors appear to prevent essential functionalities such as memory persistence, tool usage observation, and database updates. Despite the worker running normally with 8 SSE clients connected, no active sessions are reported, and the database file, while present, remains small (4.00 KB), indicating potential issues with data persistence. The user expects these PostToolUse hooks to function error-free to ensure the system can properly record and store context, but the consistent issues across tools highlight a possible systemic fault in the hook handling process.
