Split the 860+ line bin/amc-server into a modular Python package:
amc_server/
__init__.py - Package marker
context.py - Shared constants (DATA_DIR, PORT, CLAUDE_PROJECTS_DIR, etc.)
handler.py - AMCHandler class using mixin composition
logging_utils.py - Structured logging setup with signal handlers
server.py - Main entry point (ThreadingHTTPServer)
mixins/
__init__.py - Mixin package marker
control.py - Session control (dismiss, respond via Zellij)
conversation.py - Conversation history parsing (Claude JSONL format)
discovery.py - Session discovery (Codex pane inspection, Zellij cache)
http.py - HTTP response helpers (CORS, JSON, static files)
parsing.py - Session state parsing and aggregation
state.py - Session state endpoint logic
The monolithic bin/amc-server becomes a thin launcher that just imports
and calls main(). This separation enables:
- Easier testing of individual components
- Better IDE support (proper Python package structure)
- Cleaner separation of concerns (discovery vs parsing vs control)
- ThreadingHTTPServer instead of single-threaded (handles concurrent requests)

AMC — Agent Mission Control
A real-time dashboard for monitoring and interacting with Claude Code sessions.
Overview
AMC provides a unified view of all running Claude Code sessions across projects. It displays session status, conversation history, and pending questions — and allows you to respond directly from the dashboard without switching terminal tabs.
Features
- Real-time monitoring — Sessions are grouped by status (needs attention, active, starting, done) with 3-second polling
- Conversation history — View the full chat history for any session, pulled from Claude Code's JSONL logs
- Response injection — Send responses to agents directly via Zellij pane integration
- Question detection — Detects both structured
AskUserQuestionprompts and prose questions (messages ending with "?") - Session lifecycle — Automatically cleans up orphaned sessions and stale event logs
Installation
- Clone this repository
- Symlink the launcher to your PATH:
ln -s /path/to/amc/bin/amc ~/.local/bin/amc
- Configure Claude Code hooks (see Hook Setup)
Usage
amc start # Start the server and open the dashboard
amc stop # Stop the server
amc status # Check if the server is running
The dashboard opens at http://127.0.0.1:7400.
Hook Setup
AMC requires Claude Code hooks to report session state. Add this to your ~/.claude/settings.json:
{
"hooks": {
"SessionStart": [
{ "command": "/path/to/amc/bin/amc-hook" }
],
"UserPromptSubmit": [
{ "command": "/path/to/amc/bin/amc-hook" }
],
"Stop": [
{ "command": "/path/to/amc/bin/amc-hook" }
],
"SessionEnd": [
{ "command": "/path/to/amc/bin/amc-hook" }
],
"PreToolUse": [
{ "matcher": "AskUserQuestion", "command": "/path/to/amc/bin/amc-hook" }
],
"PostToolUse": [
{ "matcher": "AskUserQuestion", "command": "/path/to/amc/bin/amc-hook" }
]
}
}

Components
| Component | Description |
|---|---|
bin/amc |
Launcher script — start/stop/status commands |
bin/amc-server |
Python HTTP server serving the API and dashboard |
bin/amc-hook |
Hook script called by Claude Code to write session state |
dashboard-preact.html |
Single-file Preact dashboard |
Data Storage
All runtime data lives in ~/.local/share/amc/:
| Path | Contents |
|---|---|
sessions/*.json |
Current session state (one file per session) |
events/*.jsonl |
Event log for each session (append-only) |
server.pid |
PID file for the running server |
server.log |
Server stdout/stderr |
API Reference
| Method | Endpoint | Description |
|---|---|---|
| GET | / |
Dashboard HTML |
| GET | /api/state |
All sessions as JSON |
| GET | /api/events/{id} |
Event timeline for a session |
| GET | /api/conversation/{id}?project_dir=... |
Conversation history (from Claude Code logs) |
| POST | /api/dismiss/{id} |
Dismiss (delete) a completed session |
| POST | /api/respond/{id} |
Send a response to a session |
Response Injection
The /api/respond/{id} endpoint injects text into a session's Zellij pane. Request body:
{
"text": "your response here",
"freeform": true,
"optionCount": 3
}
text— The response to sendfreeform— If true, treats as freeform text (selects "Other" option first)optionCount— Number of options in the current question (used for freeform)
Response injection works via:
- Zellij plugin (
~/.config/zellij/plugins/zellij-send-keys.wasm) — Preferred, no focus change - write-chars fallback — Uses
zellij action write-chars, changes focus
Session Statuses
| Status | Meaning |
|---|---|
starting |
Session started, no prompt submitted yet |
active |
Session is processing work |
needs_attention |
Agent is waiting for user input (question or AskUserQuestion) |
done |
Session stopped (can be dismissed) |
Cleanup Behavior
- Orphan sessions: Sessions with missing Zellij sessions in "starting" status are auto-deleted
- Stale "starting" sessions: Sessions stuck in "starting" for >1 hour are removed
- Stale event logs: Event logs without matching sessions are deleted after 24 hours
- SessionEnd: Deletes the session file immediately
Requirements
- Python 3.8+
- Zellij (for response injection)
- Claude Code with hooks support
Optional: Zellij Plugin
For seamless response injection without focus changes, install the zellij-send-keys plugin:
# Build and install the plugin
# (See zellij-send-keys repository for instructions)
Place the compiled WASM at ~/.config/zellij/plugins/zellij-send-keys.wasm.
