AI Session System
NIIA reads conversation history from four AI coding tools, indexes them
into a single searchable database, and enables cross-model session continuity.
┌──────────────────────────────────────────────────────────────────┐
│ SESSION SOURCES │
├──────────────────────────────────────────────────────────────────┤
│ │
│ Tool Format Path │
│ ───────────────────────────────────────────────── │
│ Claude JSONL ~/.claude/projects/*/session.jsonl │
│ Codex JSONL ~/.codex/history.jsonl │
│ OpenCode SQLite ~/.local/share/opencode/opencode.db │
│ Gemini JSON ~/.gemini/tmp/*/chats/*.json │
│ │
│ All read locally. No API calls. No internet needed. │

Reading Sessions
niia session read latest # Claude (default)
niia session read latest --tool codex # Codex
niia session read latest --tool opencode # OpenCode
niia session read latest --tool gemini # Gemini
niia session read c0997679 -n 10 # Specific session, 10 messages
Indexing & Searching
First, index all sessions into a single database:
claude: 19 sessions indexed
codex: 48 entries indexed
opencode: 3 sessions indexed
gemini: 15 sessions indexed
Total: 85 items
niia session search "session gateway"
niia session search "PTY buffer fix"
niia session search "auth middleware"
NIIA Session Search: "session gateway"
======================================================================
#1 1.14 claude-session-a1b2.md
> We discussed the authentication flow and decided on JWT tokens.
#2 1.14 codex-session-c3d4.md
> Refactored the session manager to use async/await pattern.
#3 1.00 opencode-session-e5f6.md
> Traced the PTY output pipeline from daemon to renderer.
Cross-Model Continuity
The core use case: continue work across different AI models.
┌──────────────────────────────────────────────────────────────────┐
│ SCENARIO: Gemini → Claude handoff │
├──────────────────────────────────────────────────────────────────┤
│ │
│ 1. You worked 3 hours in Gemini CLI │
│ → Gemini saved chats to ~/.gemini/tmp/*/chats/*.json │
│ │
│ 2. Switch to Claude Code │
│ $ niia session read latest --tool gemini │
│ → See full Gemini conversation │
│ │
│ 3. Or search for the specific topic │
│ $ niia session search "the bug we discussed" │
│ → Finds it in Gemini session, shows context │
│ │
│ 4. Claude now has the context to continue │
│ → No re-explaining. No lost context. │
│ │
└──────────────────────────────────────────────────────────────────┘
| From | To | Command |
|---|
| Gemini → Claude | niia session read latest --tool gemini | |
| Claude → Codex | niia session read latest --tool claude | |
| Codex → OpenCode | niia session search "topic" | |
| Any → Any | niia session search "what we discussed" | |
NIIA reads each tool’s local session storage automatically. No configuration needed — it discovers and parses session files for Claude, Codex, OpenCode, and Gemini out of the box.
Separation from Documents
Document search and session search use separate databases:
| Command | Content |
|---|
niia docs search | Markdown documents |
niia session search | AI conversations |
niia search | Unified results from both |
niia search which queries both.
