Query bfzs Database

Overview

Query the bfzs SQLite databases directly to inspect sessions, messages, agent presets, and tool call history — without needing the server running.

When to Use

Debugging what tools/presets are actually being used in a session
Verifying message content without manual browser testing
Checking if the correct preset_id was applied to a session
Inspecting tool call history for a specific conversation

Quick Reference

Command	Purpose
`--sessions [--limit N] [--search KEYWORD]`	List recent sessions, with optional keyword search
`--presets`	List agent presets (all fields: model, prompt, tools, mcp, skills)
`--users`	List users and their agent access permissions
`--last`	Use the most recent session (shortcut)
`--last --msgs`	UI messages for most recent session (fast, has usage)
`--last --tools`	Tool calls for most recent session
`--msgs <session-uuid>`	UI messages from chat_ui_messages table (fast, shows usage/traces)
`<session-uuid>`	Full messages from LangGraph checkpoint
`--tools <session-uuid>`	Tool calls only, from LangGraph checkpoint
`--state`	Runtime MCP servers and tool groups status (server must be running)

Implementation

$Python = "D:\ProgramData\miniconda3\envs\py312\python.exe"
$Script = "D:\codes\lc-agent\.agents\skills\query-bfzs-db\scripts\query_session.py"

# Most common: see last session's UI messages
& $Python $Script --last --msgs

# List recent sessions
& $Python $Script --sessions --limit 20

# Search sessions by title
& $Python $Script --sessions --search "funboost"

# List agent presets (all fields)
& $Python $Script --presets

# List users and permissions
& $Python $Script --users

# Full checkpoint messages for a specific session
& $Python $Script "session-uuid-here"

# Tool calls for a specific session
& $Python $Script --tools "session-uuid-here"

Database Locations

DB	Path	Contents
Data	`D:\codes\lc-agent-bfzs\bfzs_data.db`	sessions, agent_presets, users
Checkpoint	`D:\codes\lc-agent-bfzs\bfzs_checkpoints.db`	LangGraph state with messages
