Codeman/CLAUDE.md

CLAUDE.md

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

Quick Reference

Task	Command
Dev server	npx tsx src/index.ts web
Type check	tsc --noEmit
Single test	npx vitest run test/<file>.test.ts
Production	npm run build && systemctl --user restart claudeman-web

CRITICAL: Session Safety

You may be running inside a Claudeman-managed tmux session. Before killing ANY tmux or Claude process:

1. Check: echo $CLAUDEMAN_TMUX - if 1, you're in a managed session
2. NEVER run tmux kill-session, pkill tmux, or pkill claude without confirming
3. Use the web UI or ./scripts/tmux-manager.sh instead of direct kill commands

CRITICAL: Always Test Before Deploying

NEVER COM without verifying your changes actually work. For every fix:

1. Backend changes: Hit the API endpoint with curl and verify the response
2. Frontend changes: Use Playwright to load the page and assert the UI renders correctly. Use waitUntil: 'domcontentloaded' (not networkidle — SSE keeps the connection open). Wait 3-4s for polling/async data to populate, then check element visibility, text content, and CSS values
3. Only after verification passes, proceed with COM

The production server caches static files for 1 hour (maxAge: '1h' in server.ts). After deploying frontend changes, users may need a hard refresh (Ctrl+Shift+R) to see updates.

COM Shorthand (Deployment)

When user says "COM":

1. Increment version in BOTH package.json AND CLAUDE.md (verify they match with grep version package.json && grep Version CLAUDE.md)
2. Run: git add -A && git commit -m "chore: bump version to X.XXXX" && git push && npm run build && systemctl --user restart claudeman-web

Version: 0.1561 (must match package.json for npm publish)

Project Overview

Claudeman is a Claude Code session manager with web interface and autonomous Ralph Loop. Spawns Claude CLI via PTY, streams via SSE, supports respawn cycling for 24+ hour autonomous runs.

Tech Stack: TypeScript (ES2022/NodeNext, strict mode), Node.js, Fastify, node-pty, xterm.js

TypeScript Strictness (see tsconfig.json): noUnusedLocals, noUnusedParameters, noImplicitReturns, noImplicitOverride, noFallthroughCasesInSwitch, allowUnreachableCode: false, allowUnusedLabels: false. Note: src/tui is excluded from compilation (legacy/deprecated code path).

Requirements: Node.js 18+, Claude CLI, tmux

Commands

CRITICAL: npm run dev shows CLI help, NOT the web server.

Default port: 3000 (web UI at http://localhost:3000)

# Setup
npm install                        # Install dependencies

# Development
npx tsx src/index.ts web           # Dev server (RECOMMENDED)
npx tsx src/index.ts web --https   # With TLS (only needed for remote access)
npm run typecheck                  # Type check
tsc --noEmit --watch               # Continuous type checking

# Testing (NEVER run full suite from inside Claudeman — kills tmux sessions)
# npx vitest run                   # ALL tests — DANGEROUS inside Claudeman
npx vitest run test/<file>.test.ts # Single file (SAFE)
npx vitest run -t "pattern"        # Tests matching name
npm run test:coverage              # With coverage report

# Production
npm run build
systemctl --user restart claudeman-web
journalctl --user -u claudeman-web -f

Common Gotchas

• npm run dev is NOT the web server — it shows CLI help. Use npx tsx src/index.ts web
• Single-line prompts only — writeViaMux() sends text and Enter separately; multi-line breaks Ink
• Don't kill tmux sessions blindly — Check $CLAUDEMAN_TMUX first; you might be inside one
• Never run full test suite — npx vitest run spawns/kills tmux sessions and will crash your Claudeman session. Run individual test files only.
• Global regex lastIndex sharing — ANSI_ESCAPE_PATTERN_FULL/SIMPLE have g flag; use createAnsiPatternFull/Simple() factory functions for fresh instances in loops
• DEC 2026 sync blocks — Never discard incomplete sync blocks (START without END); buffer up to 50ms then flush. See app.js:extractSyncSegments()
• Terminal writes during buffer load — Live SSE writes are queued while _isLoadingBuffer is true to prevent interleaving with historical data
• Local echo prompt scanning — Does NOT use buffer.cursorY (Ink moves it); scans buffer bottom-up for visible > prompt marker

Import Conventions

• Utilities: Import from ./utils (re-exports all): import { LRUMap, stripAnsi } from './utils'
• Types: Use type imports: import type { SessionState } from './types'
• Config: Import from specific files: import { MAX_TERMINAL_BUFFER_SIZE } from './config/buffer-limits'

Data Flow

1. Session spawns claude --dangerously-skip-permissions via node-pty
2. PTY output buffered, ANSI stripped, parsed for JSON messages
3. WebServer broadcasts to SSE clients at /api/events
4. State persists to ~/.claudeman/state.json via StateStore

Key Patterns

Input to sessions: Use session.writeViaMux() for programmatic input (respawn, auto-compact). Uses tmux send-keys -l (literal text) + send-keys Enter. All prompts must be single-line.

Terminal multiplexer: TerminalMultiplexer interface (src/mux-interface.ts) abstracts the backend. createMultiplexer() from src/mux-factory.ts creates the tmux backend.

Idle detection: Multi-layer (completion message → AI check → output silence → token stability). See docs/respawn-state-machine.md.

Token tracking: Interactive mode parses status line ("123.4k tokens"), estimates 60/40 input/output split.

Hook events: Claude Code hooks trigger notifications via /api/hook-event. Key events: permission_prompt (tool approval needed), elicitation_dialog (Claude asking question), idle_prompt (waiting for input), stop (response complete), teammate_idle (Agent Teams), task_completed (Agent Teams). See src/hooks-config.ts.

Agent Teams (experimental): TeamWatcher polls ~/.claude/teams/ for team configs and matches teams to sessions via leadSessionId. Teammates are in-process threads (not separate OS processes) and appear as standard subagents. RespawnController checks TeamWatcher.hasActiveTeammates() before triggering respawn. Enable via CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1 env var in settings.local.json. See agent-teams/ for full docs.

Circuit breaker: Prevents respawn thrashing when Claude is stuck. States: CLOSED (normal) → HALF_OPEN (testing) → OPEN (blocked). Tracks consecutive no-progress, same-error-repeated, and tests-failing-too-long. Reset via API at /api/sessions/:id/ralph-circuit-breaker/reset.

Respawn cycle metrics & health scoring: RespawnCycleMetrics tracks per-cycle outcomes (success, stuck_recovery, blocked, error). RalphLoopHealthScore computes 0-100 health with component scores (cycleSuccess, circuitBreaker, iterationProgress, aiChecker, stuckRecovery). Available via respawn status API.

Subagent-session correlation: Session parses Task tool output via BashToolParser → SubagentWatcher discovers new agent → calls session.findTaskDescriptionNear() to match description for window title.

Frontend Architecture (app.js)

The frontend is a single 16K-line vanilla JS file with these key systems:

System	Key Classes/Functions	Purpose
Terminal rendering	batchTerminalWrite(), flushPendingWrites(), chunkedTerminalWrite()	60fps batched writes with DEC 2026 sync
Local echo overlay	LocalEchoOverlay class	DOM overlay for instant mobile keystroke feedback
Mobile support	MobileDetection, KeyboardHandler, SwipeHandler, KeyboardAccessoryBar	Touch input, viewport adaptation, swipe navigation
Subagent windows	openSubagentWindow(), closeSubagentWindow(), updateConnectionLines()	Floating terminal windows with parent connection lines
Notifications	NotificationManager class	4-layer: in-app drawer, tab flash, browser API, audio beep
SSE connection	connectSSE(), addListener()	EventSource with exponential backoff (1-30s), offline queue (64KB)
Settings	openAppSettings(), apply*Visibility()	Server-backed + localStorage persistence
Focus management	FocusTrap class	Modal keyboard navigation with focus restore

Z-index layers: subagent windows (1000), plan agents (1100), log viewers (2000), image popups (3000), local echo overlay (7).

Built-in respawn presets: solo-work (3s idle, 60min), subagent-workflow (45s idle, 240min), team-lead (90s idle, 480min), overnight-autonomous (10s idle, 480min, full reset).

Keyboard shortcuts: Escape (close panels), Ctrl+? (help), Ctrl+Enter (quick start), Ctrl+W (kill session), Ctrl+Tab (next session), Ctrl+K (kill all), Ctrl+L (clear), Ctrl+Shift+R (restore size), Ctrl/Cmd +/- (font size).

Security

• HTTP Basic Auth: Optional via CLAUDEMAN_USERNAME/CLAUDEMAN_PASSWORD env vars
• CORS: Restricted to localhost only
• Security headers: X-Content-Type-Options, X-Frame-Options, CSP; HSTS if HTTPS
• Path validation (schemas.ts): Strict allowlist regex, no shell metacharacters, no traversal, must be absolute
• Env var allowlist: Only CLAUDE_CODE_* prefixes allowed; blocks PATH, LD_PRELOAD, NODE_OPTIONS, CLAUDEMAN_* keys
• File streaming TOCTOU protection: FileStreamManager calls realpathSync() twice (at validation and before spawn) to catch symlink swaps

SSE Event Categories

~80+ event types broadcast via broadcast(). Key categories:

Category	Events	Purpose
Session	session:created/updated/deleted/working/idle/exit/error/completion	Lifecycle
Terminal	session:terminal, session:clearTerminal, session:needsRefresh	Output streaming
Respawn	respawn:stateChanged/cycleStarted/blocked/aiCheck*/planCheck*/timer*	Respawn state machine
Subagent	subagent:discovered/updated/completed/tool_call/progress	Background agents
Ralph	session:ralphLoopUpdate/ralphTodoUpdate/ralphCompletionDetected	Ralph tracking
Hooks	hook:{eventName} (dynamic)	Claude Code hook events
Plan	plan:started/progress/completed/cancelled/subagent	Plan orchestration
Mux	mux:created/killed/died/statsUpdated	tmux process monitor
Image	image:detected	Screenshot detection

API Route Categories

~99 routes in server.ts:buildServer(). Key groups:

Group	Prefix	Count	Key endpoints
Sessions	/api/sessions	~20	CRUD, input, resize, interactive, shell
Respawn	/api/sessions/:id/respawn	5	start, stop, enable, config
Ralph	/api/sessions/:id/ralph-*	6	state, status, config, circuit-breaker
Plan	/api/sessions/:id/plan/*	5	task CRUD, checkpoint, history, rollback
Subagents	/api/subagents	7	list, transcript, kill, cleanup
Cases	/api/cases	5	CRUD, link, fix-plan
Scheduled	/api/scheduled	4	CRUD for scheduled runs
System	/api/status, /api/stats, /api/config, /api/settings	8	App state, config
Files	/api/sessions/:id/file*, tail-file	5	Browser, preview, raw, tail stream
Mux	/api/mux-sessions	4	tmux management, stats

Adding Features

• API endpoint: Types in types.ts, route in server.ts:buildServer(), use createErrorResponse(). Validate request bodies with Zod schemas in schemas.ts.
• SSE event: Emit via broadcast(), handle in app.js SSE listener section (search addListener()
• Session setting: Add to SessionState in types.ts, include in session.toState(), call persistSessionState()
• Hook event: Add to HookEventType in types.ts, add hook command in hooks-config.ts:generateHooksConfig(), update HookEventSchema in schemas.ts
• Mobile feature: Add to relevant mobile singleton (KeyboardHandler, KeyboardAccessoryBar, etc.), test with MobileDetection.isMobile() guard
• New test: Pick unique port (search const PORT =), add port comment to test file header. Tests use ports 3150+.

Validation: Uses Zod v4 for request validation. Define schemas in schemas.ts and use .parse() or .safeParse(). Note: Zod v4 has different API from v3 (e.g., z.object() options changed, error formatting differs).

State Files

File	Purpose
~/.claudeman/state.json	Sessions, settings, tokens, respawn config
~/.claudeman/mux-sessions.json	Tmux session metadata for recovery
~/.claudeman/settings.json	User preferences

Default Settings

UI defaults are set in src/web/public/app.js using ?? fallbacks. To change defaults, edit openAppSettings() and apply*Visibility() functions.

Key defaults: Most panels hidden (monitor, subagents shown), notifications enabled (audio disabled), subagent tracking on, Ralph tracking off.

Testing

CRITICAL: You are running inside a Claudeman-managed tmux session. Never run npx vitest run (full suite) — it spawns/kills tmux sessions and will crash your own session. Instead:

# Safe: run individual test files
npx vitest run test/<specific-file>.test.ts

# Safe: run tests matching a pattern
npx vitest run -t "pattern"

# DANGEROUS from inside Claudeman — will kill your tmux session:
# npx vitest run          ← DON'T DO THIS

Ports: Unit tests pick unique ports manually. Search const PORT = before adding new tests.

Config: Vitest with globals: true, fileParallelism: false. Unit timeout 30s.

Safety: test/setup.ts snapshots pre-existing tmux sessions at load time and never kills them. Only sessions registered via registerTestTmuxSession() get cleaned up.

Respawn tests: Use MockSession from test/respawn-test-utils.ts to avoid spawning real Claude processes.

Mobile tests: Separate Playwright-based suite in mobile-test/ with 135 device profiles. Run via npx vitest run --config mobile-test/vitest.config.ts. See mobile-test/README.md.

Screenshots ("sc")

When the user says "check the sc", "screenshot", or "sc", they mean uploaded screenshots from their mobile device. Screenshots are saved to ~/.claudeman/screenshots/ and uploaded via /upload.html on the Claudeman web UI. To view them, use the Read tool on the image files:

ls ~/.claudeman/screenshots/        # List uploaded screenshots
# Then use Read tool on individual files — Claude Code can view images natively

API: GET /api/screenshots (list), GET /api/screenshots/:name (serve), POST /api/screenshots (upload multipart/form-data). Source: src/web/public/upload.html.

Debugging

tmux list-sessions                  # List tmux sessions
tmux attach-session -t <name>       # Attach (Ctrl+B D to detach)
curl localhost:3000/api/sessions    # Check sessions
curl localhost:3000/api/status | jq # Full app state
cat ~/.claudeman/state.json | jq    # View persisted state
curl localhost:3000/api/subagents   # List background agents
curl localhost:3000/api/sessions/:id/run-summary | jq  # Session timeline

Troubleshooting

Problem	Check	Fix
Session won't start	tmux list-sessions for orphans	Kill orphaned sessions, check Claude CLI installed
Port 3000 in use	lsof -i :3000	Kill conflicting process or use --port flag
SSE not connecting	Browser console for errors	Check CORS, ensure server running
Respawn not triggering	Session settings → Respawn enabled?	Enable respawn, check idle timeout config
Terminal blank on tab switch	Network tab for /api/sessions/:id/buffer	Check session exists, restart server
Tests failing on session limits	tmux list-sessions | wc -l	Clean up: tmux list-sessions | grep test | awk -F: '{print $1}' | xargs -I{} tmux kill-session -t {}
State not persisting	cat ~/.claudeman/state.json	Check file permissions, disk space

Performance Constraints

The app must stay fast with 20 sessions and 50 agent windows:

• 60fps terminal (16ms batching + requestAnimationFrame)
• Auto-trimming buffers (2MB terminal max)
• Debounced state persistence (500ms)
• SSE adaptive batching: 16ms (normal), 32ms (moderate), 50ms (rapid); immediate flush at 32KB
• SSE backpressure handling: skip writes to backpressured clients, recover via session:needsRefresh on drain
• Cached endpoints: /api/sessions and /api/status use 1s TTL caches to avoid expensive serialization
• Frontend buffer loads: 128KB chunks via requestAnimationFrame to prevent UI jank

Terminal Anti-Flicker System

Claude Code uses Ink (React for terminals), which redraws the screen on every state change. Claudeman implements a 6-layer anti-flicker pipeline for smooth 60fps output:

PTY Output → Server Batching (16-50ms) → DEC 2026 Wrap → SSE → Client rAF → xterm.js

Key functions: server.ts:batchTerminalData(), server.ts:flushTerminalBatches(), app.js:batchTerminalWrite(), app.js:extractSyncSegments()

Typical latency: 16-32ms. Optional per-session flicker filter adds ~50ms for problematic terminals.

See docs/terminal-anti-flicker.md for full implementation details (adaptive batching, DEC 2026 markers, edge cases).

Resource Limits

Limits are centralized in src/config/buffer-limits.ts and src/config/map-limits.ts.

Buffer limits (per session):

Buffer	Max	Trim To
Terminal	2MB	1.5MB
Text output	1MB	768KB
Messages	1000	800

Map limits (global):

Resource	Max
Tracked agents	500
Concurrent sessions	50
SSE clients total	100
File watchers	500

Use LRUMap for bounded caches with eviction, StaleExpirationMap for TTL-based cleanup.

Memory Leak Prevention

Frontend runs long (24+ hour sessions); all Maps/timers must be cleaned up.

Cleanup Patterns

When adding new event listeners or timers:

1. Store handler references for later removal
2. Add cleanup to appropriate stop() or cleanup*() method
3. For singleton watchers, store refs in class properties and remove in server stop()

Backend: Clear Maps in stop(), null promise callbacks on error, remove watcher listeners on shutdown. Use CleanupManager for centralized disposal — supports timers, intervals, watchers, listeners, streams. Guard async callbacks with if (this.cleanup.isStopped) return.

Frontend: Store drag/resize handlers on elements, clean up in close*() functions. SSE reconnect calls handleInit() which resets state. SSE listeners are tracked in an array and removed on reconnect to prevent accumulation.

Run npx vitest run test/memory-leak-prevention.test.ts to verify patterns.

Common Workflows

Investigating a bug: Start dev server (npx tsx src/index.ts web), reproduce in browser, check terminal output and ~/.claudeman/state.json for clues.

Adding a new API endpoint: Define types in types.ts, add route in server.ts:buildServer(), broadcast SSE events if needed, handle in app.js:handleSSEEvent().

Modifying respawn behavior: Study docs/respawn-state-machine.md first. The state machine is in respawn-controller.ts. Use MockSession from test/respawn-test-utils.ts for testing.

Modifying mobile behavior: Mobile singletons (MobileDetection, KeyboardHandler, SwipeHandler, KeyboardAccessoryBar) all have init()/cleanup() lifecycle. KeyboardHandler uses visualViewport API for iOS keyboard detection (100px threshold for address bar drift). All mobile handlers are re-initialized after SSE reconnect to prevent stale closures.

Adding a file watcher: Use ImageWatcher as a template pattern — chokidar with awaitWriteFinish, burst throttling (max 20/10s), debouncing (200ms), and auto-ignore of node_modules/.git/dist/.
