DeepChat Data Import

Overview

Use this skill to design or implement importers for DeepChat local data. Treat DeepChat's SQLite schema as an internal but documentable contract: inspect the current schema when precision matters, prefer read-only snapshots, and avoid writing to a live profile.

Workflow

1. Identify the source: live DeepChat profile, copied profile, sync backup, exported agent.db, or

legacy chat.db.

1. Read references/data-locations.md to locate agent.db,

sidecar files, encryption metadata, and backup paths.

1. Read references/sqlite-access.md before opening SQLite. Decide

whether the database is unencrypted, can be unlocked through Electron safeStorage, or must ask the user for the SQLite password.

1. Read references/schema-reference.md for provider config,

settings, session, message, and legacy table relationships.

1. Read references/import-recipes.md when writing extractor code,

mapping DeepChat data to another app, or creating a compatibility import.

Safety Rules

• Get explicit user consent before reading local DeepChat data. Provider keys, OAuth tokens, MCP

env vars, prompt text, message traces, and chat content may be sensitive.

• Never open the active agent.db read-write from a third-party tool. Copy agent.db,

agent.db-wal, and agent.db-shm, or use SQLite backup APIs through DeepChat itself.

• If DeepChat is running, either ask the user to quit it or make a WAL-aware snapshot before import.
• Prefer parameterized key APIs for SQLCipher passwords. Do not interpolate passwords into SQL.
• Redact secrets by default in logs, telemetry, previews, and generated sample output.
• When the schema has changed, inspect schema_versions, sqlite_master, and the table classes

under src/main/presenter/sqlitePresenter/tables/ before assuming column availability.
