Zellij Driver (znav)

Overview

znav is a Redis-backed Zellij pane manager that tracks developer intent and cognitive context across terminal sessions. It enables programmatic control of Zellij tabs and panes, making it ideal for orchestrating parallel agentic workflows.

Core Philosophy: Capture what you're working on, not just what you typed. znav bridges the gap between terminal activity and developer intent, enabling AI agents to understand and resume work context.

Core Capabilities

1. Tab and Pane Management

Create Named Tabs:

znav tab my-feature                    # Switch to or create tab
znav tab create myapp --correlation-id pr-42  # Tab with correlation ID
znav pane my-task --tab my-feature     # Create pane in specific tab

Pane Operations:

znav pane api-refactor                 # Create/open pane (auto-creates tab if needed)
znav pane info api-refactor            # Get pane metadata
znav list                              # Tree view of all sessions/tabs/panes
znav reconcile                         # Sync Redis state with Zellij layout

Batch Pane Creation:

# Create multiple panes in a single command
znav pane batch --tab "myapp(fixes)" --panes fix-auth,fix-errors,fix-docs

# With working directories for each pane
znav pane batch --tab "myapp(fixes)" \
    --panes fix-auth,fix-errors,fix-docs \
    --cwd ../fix-auth,../fix-errors,../fix-docs

# Horizontal layout (stacked instead of side-by-side)
znav pane batch --tab "myapp(fixes)" --panes a,b,c --layout horizontal

2. Intent Tracking (znav v2.0)

Track what you're working on, not just commands:

Log Intent Entries:

# Simple checkpoint
znav pane log my-feature "Fixed authentication bug"

# Milestone with artifacts
znav pane log api-refactor "Completed REST API redesign" \
    --type milestone --artifacts src/api.rs docs/api.md

# Exploration session
znav pane log research "Investigated caching strategies" --type exploration

# Agent-generated entry
znav pane log my-feature "Completed task analysis" --source agent

Entry Types:

• checkpoint (default): Regular progress markers
• milestone: Major accomplishments worth highlighting
• exploration: Research or investigative work

Entry Sources:

• manual (default): Human-created entries
• agent: Created by AI during assisted workflow
• automated: System-generated from activity detection

3. History Retrieval

Multiple output formats for different use cases:

# Human-readable (default)
znav pane history my-feature

# JSON for programmatic access
znav pane history my-feature --format json

# Compact JSON for piping
znav pane history my-feature --format json-compact | jq '.entries[0]'

# Markdown export (Obsidian-compatible)
znav pane history my-feature --format markdown > session.md

# LLM-optimized context for agent integration (~1000 tokens)
znav pane history my-feature --format context

4. LLM-Powered Snapshots

Auto-generate intent summaries from recent work:

# Generate AI summary of recent activity
znav pane snapshot my-feature

# Requires LLM configuration and consent
znav config set llm.provider anthropic
znav config consent --grant

Supported Providers:

• anthropic (Claude) - default model: claude-sonnet-4-20250514
• openai (GPT) - default model: gpt-4o-mini
• ollama (local) - default model: llama3.2
• none - disabled

5. Configuration Management

znav config show                       # View all settings
znav config set redis_url redis://...  # Update Redis connection
znav config consent --grant            # Allow LLM data sharing
znav config consent --revoke           # Revoke LLM consent

Agentic Workflow Patterns

Pattern 1: Parallel PR Fixes

When implementing multiple fixes from a PR in parallel:

# 1. Create a tab for the fixes with correlation ID for traceability
znav tab create "myapp(fixes)" --correlation-id pr-42

# 2. Create all panes in one batch command
znav pane batch --tab "myapp(fixes)-pr-42" --panes fix-auth,fix-errors,fix-docs

# 3. Each pane can be worked on by a separate agent
# Agent in fix-auth pane:
znav pane log fix-auth "Starting auth token refresh fix" --source agent
# ... agent does work ...
znav pane log fix-auth "Completed auth fix" --type milestone --source agent

Pattern 2: iMi Integration

Combine with iMi worktrees for branch-per-pane isolation:

# 1. Create worktrees with iMi
imi add fix auth-refresh
imi add fix error-handling
imi add fix api-docs

# 2. Create Zellij workspace with all panes and working directories in one command
znav tab create "myapp(fixes)"
znav pane batch --tab "myapp(fixes)" \
    --panes fix-auth,fix-errors,fix-docs \
    --cwd ~/code/myapp/fix-auth-refresh,~/code/myapp/fix-error-handling,~/code/myapp/fix-api-docs

Pattern 3: Session Resumption

When returning to a pane, znav displays the last intent:

# First session
znav pane my-feature
znav pane log my-feature "Implementing user authentication flow"
# ... work happens ...

# Later session (shows resume context)
znav pane my-feature
# Output: "Resuming: ● Implementing user authentication flow (2 hours ago)"

Pattern 4: Agent Context Injection

Get condensed context for LLM prompts:

# Get ~1000 token context summary
CONTEXT=$(znav pane history my-feature --format context)

# Inject into agent prompt
echo "Continue this work session:\n$CONTEXT"

Tab Naming Conventions

For agentic workflows, use consistent naming:

Current Limitations

Not Yet Implemented (Sprint 5/6 backlog):

• Bloodbank event publishing
• MCP tool exposure
• Session restoration/snapshotting

Zellij Version:

• Requires Zellij >= 0.39.0

Data Model

IntentEntry:

{
  "id": "uuid",
  "timestamp": "2025-01-06T12:00:00Z",
  "summary": "What you were working on",
  "entry_type": "checkpoint|milestone|exploration",
  "source": "manual|agent|automated",
  "artifacts": ["file1.rs", "file2.ts"],
  "commands_run": 15,
  "goal_delta": "Progress description"
}

PaneRecord:

• Tracks session, tab, pane name, position
• Stores metadata for navigation
• Marks stale panes after reconciliation

Redis Keyspace

znav v2.0 uses the znav: keyspace:

znav:pane:{name}          # Pane metadata hash
znav:intent:{name}        # Intent history list (LPUSH/LRANGE)

Migration from v1.0 (znav:) keyspace:

znav migrate --dry-run     # Preview migration
znav migrate               # Execute migration

Quick Reference

• Architecture: See docs/ENGINEERING_STANDARDS.md for anti-patterns and patterns.

Integration Points

33GOD Ecosystem:

• iMi: Worktree management for branch isolation
• Bloodbank: Event publishing for workflow triggers (planned)
• Jelmore: Session correlation tracking (planned)
• Flume: Task coordination across panes (planned)

Claude Code:

• Use --format context for prompt injection
• Use --source agent for agent-created entries
• Use --format json for programmatic processing
