+# Claude Code — Hermes Orchestration Guide
+
+Delegate coding tasks to [Claude Code](https://code.claude.com/docs/en/cli-reference) (Anthropic's autonomous coding agent CLI) via the Hermes terminal. Claude Code v2.x can read files, write code, run shell commands, spawn subagents, and manage git workflows autonomously.
+
+## Prerequisites
+
+- **Install:** `npm install -g @anthropic-ai/claude-code`
+- **Auth:** run `claude` once to log in (browser OAuth for Pro/Max, or set `ANTHROPIC_API_KEY`)
+- **Console auth:** `claude auth login --console` for API key billing
+- **SSO auth:** `claude auth login --sso` for Enterprise
+- **Check status:** `claude auth status` (JSON) or `claude auth status --text` (human-readable)
+- **Health check:** `claude doctor` — checks auto-updater and installation health
+- **Version check:** `claude --version` (requires v2.x+)
+- **Update:** `claude update` or `claude upgrade`
+
+## Two Orchestration Modes
+
+Hermes interacts with Claude Code in two fundamentally different ways. Choose based on the task.
+
+### Mode 1: Print Mode (`-p`) — Non-Interactive (PREFERRED for most tasks)
+
+Print mode runs a one-shot task, returns the result, and exits. No PTY needed. No interactive prompts. This is the cleanest integration path.
+
+```
+terminal(command="claude -p 'Add error handling to all API calls in src/' --allowedTools 'Read,Edit' --max-turns 10", workdir="/path/to/project", timeout=120)
+```
+
+**When to use print mode:**
+- One-shot coding tasks (fix a bug, add a feature, refactor)
+- CI/CD automation and scripting
+- Structured data extraction with `--json-schema`
+- Piped input processing (`cat file | claude -p "analyze this"`)
+- Any task where you don't need multi-turn conversation
+
+**Print mode skips ALL interactive dialogs** — no workspace trust prompt, no permission confirmations. This makes it ideal for automation.
+
+### Mode 2: Interactive PTY via tmux — Multi-Turn Sessions
+
+Interactive mode gives you a full conversational REPL where you can send follow-up prompts, use slash commands, and watch Claude work in real time. **Requires tmux orchestration.**
+
+```
+# Start a tmux session
+terminal(command="tmux new-session -d -s claude-work -x 140 -y 40")
+
+# Launch Claude Code inside it
+terminal(command="tmux send-keys -t claude-work 'cd /path/to/project && claude' Enter")
+
+# Wait for startup, then send your task
+# (after ~3-5 seconds for the welcome screen)
+terminal(command="sleep 5 && tmux send-keys -t claude-work 'Refactor the auth module to use JWT tokens' Enter")
+
+# Monitor progress by capturing the pane
+terminal(command="sleep 15 && tmux capture-pane -t claude-work -p -S -50")
+
+# Send follow-up tasks
+terminal(command="tmux send-keys -t claude-work 'Now add unit tests for the new JWT code' Enter")
+
+# Exit when done
+terminal(command="tmux send-keys -t claude-work '/exit' Enter")
+```
+
+**When to use interactive mode:**
+- Multi-turn iterative work (refactor → review → fix → test cycle)
+- Tasks requiring human-in-the-loop decisions
+- Exploratory coding sessions
+- When you need to use Claude's slash commands (`/compact`, `/review`, `/model`)
+
+## PTY Dialog Handling (CRITICAL for Interactive Mode)
+
+Claude Code presents up to two confirmation dialogs on first launch. You MUST handle these via tmux send-keys:
+
+### Dialog 1: Workspace Trust (first visit to a directory)
+```
+❯ 1. Yes, I trust this folder    ← DEFAULT (just press Enter)
+  2. No, exit
+```
+**Handling:** `tmux send-keys -t <session> Enter` — default selection is correct.
+
+### Dialog 2: Bypass Permissions Warning (only with --dangerously-skip-permissions)
+```
+❯ 1. No, exit                    ← DEFAULT (WRONG choice!)
+  2. Yes, I accept
+```
+**Handling:** Must navigate DOWN first, then Enter:
+```
+tmux send-keys -t <session> Down && sleep 0.3 && tmux send-keys -t <session> Enter
+```
+
+### Robust Dialog Handling Pattern
+```
+# Launch with permissions bypass
+terminal(command="tmux send-keys -t claude-work 'claude --dangerously-skip-permissions \"your task\"' Enter")
+
+# Handle trust dialog (Enter for default "Yes")
+terminal(command="sleep 4 && tmux send-keys -t claude-work Enter")
+
+# Handle permissions dialog (Down then Enter for "Yes, I accept")
+terminal(command="sleep 3 && tmux send-keys -t claude-work Down && sleep 0.3 && tmux send-keys -t claude-work Enter")
+
+# Now wait for Claude to work
+terminal(command="sleep 15 && tmux capture-pane -t claude-work -p -S -60")
+```
+
+**Note:** After the first trust acceptance for a directory, the trust dialog won't appear again. Only the permissions dialog recurs each time you use `--dangerously-skip-permissions`.
+

+
+## Print Mode Deep Dive
+
+### Structured JSON Output
+```
+terminal(command="claude -p 'Analyze auth.py for security issues' --output-format json --max-turns 5", workdir="/project", timeout=120)
+```
+
+Returns a JSON object with:
+```json
+{
+  "type": "result",
+  "subtype": "success",
+  "result": "The analysis text...",
+  "session_id": "75e2167f-...",
+  "num_turns": 3,
+  "total_cost_usd": 0.0787,
+  "duration_ms": 10276,
+  "stop_reason": "end_turn",
+  "terminal_reason": "completed",
+  "usage": { "input_tokens": 5, "output_tokens": 603, ... },
+  "modelUsage": { "claude-sonnet-4-6": { "costUSD": 0.078, "contextWindow": 200000 } }
+}
+```
+
+**Key fields:** `session_id` for resumption, `num_turns` for agentic loop count, `total_cost_usd` for spend tracking, `subtype` for success/error detection (`success`, `error_max_turns`, `error_budget`).
+
+### Streaming JSON Output
+For real-time token streaming, use `stream-json` with `--verbose`:
+```
+terminal(command="claude -p 'Write a summary' --output-format stream-json --verbose --include-partial-messages", timeout=60)
+```
+
+Returns newline-delimited JSON events. Filter with jq for live text:
+```
+claude -p "Explain X" --output-format stream-json --verbose --include-partial-messages | \
+  jq -rj 'select(.type == "stream_event" and .event.delta.type? == "text_delta") | .event.delta.text'
+```
+
+Stream events include `system/api_retry` with `attempt`, `max_retries`, and `error` fields (e.g., `rate_limit`, `billing_error`).
+
+### Bidirectional Streaming
+For real-time input AND output streaming:
+```
+claude -p "task" --input-format stream-json --output-format stream-json --replay-user-messages
+```
+`--replay-user-messages` re-emits user messages on stdout for acknowledgment.
+
+### Piped Input
+```
+# Pipe a file for analysis
+terminal(command="cat src/auth.py | claude -p 'Review this code for bugs' --max-turns 1", timeout=60)
+
+# Pipe multiple files
+terminal(command="cat src/*.py | claude -p 'Find all TODO comments' --max-turns 1", timeout=60)
+
+# Pipe command output
+terminal(command="git diff HEAD~3 | claude -p 'Summarize these changes' --max-turns 1", timeout=60)
+```
+
+### JSON Schema for Structured Extraction
+```
+terminal(command="claude -p 'List all functions in src/' --output-format json --json-schema '{\"type\":\"object\",\"properties\":{\"functions\":{\"type\":\"array\",\"items\":{\"type\":\"string\"}}},\"required\":[\"functions\"]}' --max-turns 5", workdir="/project", timeout=90)
+```
+
+Parse `structured_output` from the JSON result. Claude validates output against the schema before returning.
+
+### Session Continuation
+```
+# Start a task
+terminal(command="claude -p 'Start refactoring the database layer' --output-format json --max-turns 10 > /tmp/session.json", workdir="/project", timeout=180)
+
+# Resume with session ID
+terminal(command="claude -p 'Continue and add connection pooling' --resume $(cat /tmp/session.json | python3 -c 'import json,sys; print(json.load(sys.stdin)[\"session_id\"])') --max-turns 5", workdir="/project", timeout=120)
+
+# Or resume the most recent session in the same directory
+terminal(command="claude -p 'What did you do last time?' --continue --max-turns 1", workdir="/project", timeout=30)
+
+# Fork a session (new ID, keeps history)
+terminal(command="claude -p 'Try a different approach' --resume <id> --fork-session --max-turns 10", workdir="/project", timeout=120)
+```
+
+### Bare Mode for CI/Scripting
+```
+terminal(command="claude --bare -p 'Run all tests and report failures' --allowedTools 'Read,Bash' --max-turns 10", workdir="/project", timeout=180)
+```
+
+`--bare` skips hooks, plugins, MCP discovery, and CLAUDE.md loading. Fastest startup. Requires `ANTHROPIC_API_KEY` (skips OAuth).
+
+To selectively load context in bare mode:
+| To load | Flag |
+|---------|------|
+| System prompt additions | `--append-system-prompt "text"` or `--append-system-prompt-file path` |
+| Settings | `--settings <file-or-json>` |
+| MCP servers | `--mcp-config <file-or-json>` |
+| Custom agents | `--agents '<json>'` |
+
+### Fallback Model for Overload
+```
+terminal(command="claude -p 'task' --fallback-model haiku --max-turns 5", timeout=90)
+```
+Automatically falls back to the specified model when the default is overloaded (print mode only).

+```
+Read                    # All file reading
+Edit                    # File editing (existing files)
+Write                   # File creation (new files)
+Bash                    # All shell commands
+Bash(git *)             # Only git commands
+Bash(git commit *)      # Only git commit commands
+Bash(npm run lint:*)    # Pattern matching with wildcards
+WebSearch               # Web search capability
+WebFetch                # Web page fetching
+mcp__<server>__<tool>   # Specific MCP tool
+```
+
+## Settings & Configuration
+
+### Settings Hierarchy (highest to lowest priority)
+1. **CLI flags** — override everything
+2. **Local project:** `.claude/settings.local.json` (personal, gitignored)
+3. **Project:** `.claude/settings.json` (shared, git-tracked)
+4. **User:** `~/.claude/settings.json` (global)
+
+### Permissions in Settings
+```json
+{
+  "permissions": {
+    "allow": ["Bash(npm run lint:*)", "WebSearch", "Read"],
+    "ask": ["Write(*.ts)", "Bash(git push*)"],
+    "deny": ["Read(.env)", "Bash(rm -rf *)"]
+  }
+}
+```
+
+### Memory Files (CLAUDE.md) Hierarchy
+1. **Global:** `~/.claude/CLAUDE.md` — applies to all projects
+2. **Project:** `./CLAUDE.md` — project-specific context (git-tracked)
+3. **Local:** `.claude/CLAUDE.local.md` — personal project overrides (gitignored)
+
+Use the `#` prefix in interactive mode to quickly add to memory: `# Always use 2-space indentation`.
+
+## Interactive Session: Slash Commands
+
+### Session & Context
+| Command | Purpose |
+|---------|---------|
+| `/help` | Show all commands (including custom and MCP commands) |
+| `/compact [focus]` | Compress context to save tokens; CLAUDE.md survives compaction. E.g., `/compact focus on auth logic` |
+| `/clear` | Wipe conversation history for a fresh start |
+| `/context` | Visualize context usage as a colored grid with optimization tips |
+| `/cost` | View token usage with per-model and cache-hit breakdowns |
+| `/resume` | Switch to or resume a different session |
+| `/rewind` | Revert to a previous checkpoint in conversation or code |
+| `/btw <question>` | Ask a side question without adding to context cost |
+| `/status` | Show version, connectivity, and session info |
+| `/todos` | List tracked action items from the conversation |
+| `/exit` or `Ctrl+D` | End session |
+
+### Development & Review
+| Command | Purpose |
+|---------|---------|
+| `/review` | Request code review of current changes |
+| `/security-review` | Perform security analysis of current changes |
+| `/plan [description]` | Enter Plan mode with auto-start for task planning |
+| `/loop [interval]` | Schedule recurring tasks within the session |
+| `/batch` | Auto-create worktrees for large parallel changes (5-30 worktrees) |
+
+### Configuration & Tools
+| Command | Purpose |
+|---------|---------|
+| `/model [model]` | Switch models mid-session (use arrow keys to adjust effort) |
+| `/effort [level]` | Set reasoning effort: `low`, `medium`, `high`, `max`, or `auto` |
+| `/init` | Create a CLAUDE.md file for project memory |
+| `/memory` | Open CLAUDE.md for editing |
+| `/config` | Open interactive settings configuration |
+| `/permissions` | View/update tool permissions |
+| `/agents` | Manage specialized subagents |
+| `/mcp` | Interactive UI to manage MCP servers |
+| `/add-dir` | Add additional working directories (useful for monorepos) |
+| `/usage` | Show plan limits and rate limit status |
+| `/voice` | Enable push-to-talk voice mode (20 languages; hold Space to record, release to send) |
+| `/release-notes` | Interactive picker for version release notes |
+
+### Custom Slash Commands
+Create `.claude/commands/<name>.md` (project-shared) or `~/.claude/commands/<name>.md` (personal):
+
+```markdown
+# .claude/commands/deploy.md
+Run the deploy pipeline:
+1. Run all tests
+2. Build the Docker image
+3. Push to registry
+4. Update the $ARGUMENTS environment (default: staging)
+```
+
+Usage: `/deploy production` — `$ARGUMENTS` is replaced with the user's input.
+
+### Skills (Natural Language Invocation)
+Unlike slash commands (manually invoked), skills in `.claude/skills/` are markdown guides that Claude invokes automatically via natural language when the task matches:
+
+```markdown
+# .claude/skills/database-migration.md
+When asked to create or modify database migrations:
+1. Use Alembic for migration generation
+2. Always create a rollback function
+3. Test migrations against a local database copy
+```
+
+## Interactive Session: Keyboard Shortcuts
+
+### General Controls
+| Key | Action |
+|-----|--------|
+| `Ctrl+C` | Cancel current input or generation |
+| `Ctrl+D` | Exit session |
+| `Ctrl+R` | Reverse search command history |
+| `Ctrl+B` | Background a running task |
+| `Ctrl+V` | Paste image into conversation |
+| `Ctrl+O` | Transcript mode — see Claude's thinking process |
+| `Ctrl+G` or `Ctrl+X Ctrl+E` | Open prompt in external editor |
+| `Esc Esc` | Rewind conversation or code state / summarize |
+
+### Mode Toggles
+| Key | Action |
+|-----|--------|
+| `Shift+Tab` | Cycle permission modes (Normal → Auto-Accept → Plan) |
+| `Alt+P` | Switch model |
+| `Alt+T` | Toggle thinking mode |
+| `Alt+O` | Toggle Fast Mode |
+
+### Multiline Input
+| Key | Action |
+|-----|--------|
+| `\` + `Enter` | Quick newline |
+| `Shift+Enter` | Newline (alternative) |
+| `Ctrl+J` | Newline (alternative) |
+
+### Input Prefixes
+| Prefix | Action |
+|--------|--------|
+| `!` | Execute bash directly, bypassing AI (e.g., `!npm test`). Use `!` alone to toggle shell mode. |
+| `@` | Reference files/directories with autocomplete (e.g., `@./src/api/`) |
+| `#` | Quick add to CLAUDE.md memory (e.g., `# Use 2-space indentation`) |
+| `/` | Slash commands |
+
+### Pro Tip: "ultrathink"
+Use the keyword "ultrathink" in your prompt for maximum reasoning effort on a specific turn. This triggers the deepest thinking mode regardless of the current `/effort` setting.
+
+## PR Review Pattern
+
+### Quick Review (Print Mode)
+```
+terminal(command="cd /path/to/repo && git diff main...feature-branch | claude -p 'Review this diff for bugs, security issues, and style problems. Be thorough.' --max-turns 1", timeout=60)
+```
+
+### Deep Review (Interactive + Worktree)
+```
+terminal(command="tmux new-session -d -s review -x 140 -y 40")
+terminal(command="tmux send-keys -t review 'cd /path/to/repo && claude -w pr-review' Enter")
+terminal(command="sleep 5 && tmux send-keys -t review Enter")  # Trust dialog
+terminal(command="sleep 2 && tmux send-keys -t review 'Review all changes vs main. Check for bugs, security issues, race conditions, and missing tests.' Enter")
+terminal(command="sleep 30 && tmux capture-pane -t review -p -S -60")
+```
+
+### PR Review from Number
+```
+terminal(command="claude -p 'Review this PR thoroughly' --from-pr 42 --max-turns 10", workdir="/path/to/repo", timeout=120)
+```
+
+### Claude Worktree with tmux
+```
+terminal(command="claude -w feature-x --tmux", workdir="/path/to/repo")
+```
+Creates an isolated git worktree at `.claude/worktrees/feature-x` AND a tmux session for it. Uses iTerm2 native panes when available; add `--tmux=classic` for traditional tmux.
+
+## Parallel Claude Instances
+
+Run multiple independent Claude tasks simultaneously:
+
+```
+# Task 1: Fix backend
+terminal(command="tmux new-session -d -s task1 -x 140 -y 40 && tmux send-keys -t task1 'cd ~/project && claude -p \"Fix the auth bug in src/auth.py\" --allowedTools \"Read,Edit\" --max-turns 10' Enter")
+
+# Task 2: Write tests
+terminal(command="tmux new-session -d -s task2 -x 140 -y 40 && tmux send-keys -t task2 'cd ~/project && claude -p \"Write integration tests for the API endpoints\" --allowedTools \"Read,Write,Bash\" --max-turns 15' Enter")
+
+# Task 3: Update docs
+terminal(command="tmux new-session -d -s task3 -x 140 -y 40 && tmux send-keys -t task3 'cd ~/project && claude -p \"Update README.md with the new API endpoints\" --allowedTools \"Read,Edit\" --max-turns 5' Enter")
+
+# Monitor all
+terminal(command="sleep 30 && for s in task1 task2 task3; do echo '=== '$s' ==='; tmux capture-pane -t $s -p -S -5 2>/dev/null; done")
+```
+
+## CLAUDE.md — Project Context File
+
+Claude Code auto-loads `CLAUDE.md` from the project root. Use it to persist project context:
+
+```markdown
+# Project: My API
+
+## Architecture
+- FastAPI backend with SQLAlchemy ORM
+- PostgreSQL database, Redis cache
+- pytest for testing with 90% coverage target
+
+## Key Commands
+- `make test` — run full test suite
+- `make lint` — ruff + mypy
+- `make dev` — start dev server on :8000
+
+## Code Standards
+- Type hints on all public functions
+- Docstrings in Google style
+- 2-space indentation for YAML, 4-space for Python
+- No wildcard imports
+```
+
+**Be specific.** Instead of "Write good code", use "Use 2-space indentation for JS" or "Name test files with `.test.ts` suffix." Specific instructions save correction cycles.
+
+### Rules Directory (Modular CLAUDE.md)
+For projects with many rules, use the rules directory instead of one massive CLAUDE.md:
+- **Project rules:** `.claude/rules/*.md` — team-shared, git-tracked
+- **User rules:** `~/.claude/rules/*.md` — personal, global
+
+Each `.md` file in the rules directory is loaded as additional context. This is cleaner than cramming everything into a single CLAUDE.md.
+
+### Auto-Memory
+Claude automatically stores learned project context in `~/.claude/projects/<project>/memory/`.
+- **Limit:** 25KB or 200 lines per project
+- This is separate from CLAUDE.md — it's Claude's own notes about the project, accumulated across sessions
+
+## Custom Subagents
+
+Define specialized agents in `.claude/agents/` (project), `~/.claude/agents/` (personal), or via `--agents` CLI flag (session):
+
+### Agent Location Priority
+1. `.claude/agents/` — project-level, team-shared
+2. `--agents` CLI flag — session-specific, dynamic
+3. `~/.claude/agents/` — user-level, personal
+
+### Creating an Agent
+```markdown
+# .claude/agents/security-reviewer.md
+---
+name: security-reviewer
+description: Security-focused code review
+model: opus
+tools: [Read, Bash]
+---
+You are a senior security engineer. Review code for:
+- Injection vulnerabilities (SQL, XSS, command injection)
+- Authentication/authorization flaws
+- Secrets in code
+- Unsafe deserialization
+```
+
+Invoke via: `@security-reviewer review the auth module`
+
+### Dynamic Agents via CLI
+```
+terminal(command="claude --agents '{\"reviewer\": {\"description\": \"Reviews code\", \"prompt\": \"You are a code reviewer focused on performance\"}}' -p 'Use @reviewer to check auth.py'", timeout=120)
+```
+
+Claude can orchestrate multiple agents: "Use @db-expert to optimize queries, then @security to audit the changes."
+
+## Hooks — Automation on Events
+
+Configure in `.claude/settings.json` (project) or `~/.claude/settings.json` (global):
+
+```json
+{
+  "hooks": {
+    "PostToolUse": [{
+      "matcher": "Write(*.py)",
+      "hooks": [{"type": "command", "command": "ruff check --fix $CLAUDE_FILE_PATHS"}]
+    }],
+    "PreToolUse": [{
+      "matcher": "Bash",
+      "hooks": [{"type": "command", "command": "if echo \"$CLAUDE_TOOL_INPUT\" | grep -q 'rm -rf'; then echo 'Blocked!' && exit 2; fi"}]
+    }],
+    "Stop": [{
+      "hooks": [{"type": "command", "command": "echo 'Claude finished a response' >> /tmp/claude-activity.log"}]
+    }]
+  }
+}
+```
+
+### All 8 Hook Types
+| Hook | When it fires | Common use |
+|------|--------------|------------|
+| `UserPromptSubmit` | Before Claude processes a user prompt | Input validation, logging |
+| `PreToolUse` | Before tool execution | Security gates, block dangerous commands (exit 2 = block) |
+| `PostToolUse` | After a tool finishes | Auto-format code, run linters |
+| `Notification` | On permission requests or input waits | Desktop notifications, alerts |
+| `Stop` | When Claude finishes a response | Completion logging, status updates |
+| `SubagentStop` | When a subagent completes | Agent orchestration |
+| `PreCompact` | Before context memory is cleared | Backup session transcripts |
+| `SessionStart` | When a session begins | Load dev context (e.g., `git status`) |
+
+### Hook Environment Variables
+| Variable | Content |
+|----------|---------|
+| `CLAUDE_PROJECT_DIR` | Current project path |
+| `CLAUDE_FILE_PATHS` | Files being modified |
+| `CLAUDE_TOOL_INPUT` | Tool parameters as JSON |
+
+### Security Hook Examples
+```json
+{
+  "PreToolUse": [{
+    "matcher": "Bash",
+    "hooks": [{"type": "command", "command": "if echo \"$CLAUDE_TOOL_INPUT\" | grep -qE 'rm -rf|git push.*--force|:(){ :|:& };:'; then echo 'Dangerous command blocked!' && exit 2; fi"}]
+  }]
+}
+```
+
+## MCP Integration
+
+Add external tool servers for databases, APIs, and services:
+
+```
+# GitHub integration
+terminal(command="claude mcp add -s user github -- npx @modelcontextprotocol/server-github", timeout=30)
+
+# PostgreSQL queries
+terminal(command="claude mcp add -s local postgres -- npx @anthropic-ai/server-postgres --connection-string postgresql://localhost/mydb", timeout=30)
+
+# Puppeteer for web testing
+terminal(command="claude mcp add puppeteer -- npx @anthropic-ai/server-puppeteer", timeout=30)
+```
+
+### MCP Scopes
+| Flag | Scope | Storage |
+|------|-------|---------|
+| `-s user` | Global (all projects) | `~/.claude.json` |
+| `-s local` | This project (personal) | `.claude/settings.local.json` (gitignored) |
+| `-s project` | This project (team-shared) | `.claude/settings.json` (git-tracked) |
+
+### MCP in Print/CI Mode
+```
+terminal(command="claude --bare -p 'Query database' --mcp-config mcp-servers.json --strict-mcp-config", timeout=60)
+```
+`--strict-mcp-config` ignores all MCP servers except those from `--mcp-config`.
+
+Reference MCP resources in chat: `@github:issue://123`
+
+### MCP Limits & Tuning
+- **Tool descriptions:** 2KB cap per server for tool descriptions and server instructions
+- **Result size:** Default capped; use `maxResultSizeChars` annotation to allow up to **500K** characters for large outputs
+- **Output tokens:** `export MAX_MCP_OUTPUT_TOKENS=50000` — cap output from MCP servers to prevent context flooding
+- **Transports:** `stdio` (local process), `http` (remote), `sse` (server-sent events)
+
+## Monitoring Interactive Sessions
+
+### Reading the TUI Status
+```
+# Periodic capture to check if Claude is still working or waiting for input
+terminal(command="tmux capture-pane -t dev -p -S -10")
+```
+
+Look for these indicators:
+- `❯` at bottom = waiting for your input (Claude is done or asking a question)
+- `●` lines = Claude is actively using tools (reading, writing, running commands)
+- `⏵⏵ bypass permissions on` = status bar showing permissions mode
+- `◐ medium · /effort` = current effort level in status bar
+- `ctrl+o to expand` = tool output was truncated (can be expanded interactively)
+
+### Context Window Health
+Use `/context` in interactive mode to see a colored grid of context usage. Key thresholds:
+- **< 70%** — Normal operation, full precision
+- **70-85%** — Precision starts dropping, consider `/compact`
+- **> 85%** — Hallucination risk spikes significantly, use `/compact` or `/clear`
+
+## Environment Variables
+
+| Variable | Effect |
+|----------|--------|
+| `ANTHROPIC_API_KEY` | API key for authentication (alternative to OAuth) |
+| `CLAUDE_CODE_EFFORT_LEVEL` | Default effort: `low`, `medium`, `high`, `max`, or `auto` |
+| `MAX_THINKING_TOKENS` | Cap thinking tokens (set to `0` to disable thinking entirely) |
+| `MAX_MCP_OUTPUT_TOKENS` | Cap output from MCP servers (default varies; set e.g., `50000`) |
+| `CLAUDE_CODE_NO_FLICKER=1` | Enable alt-screen rendering to eliminate terminal flicker |
+| `CLAUDE_CODE_SUBPROCESS_ENV_SCRUB` | Strip credentials from sub-processes for security |
+
+## Cost & Performance Tips
+
+1. **Use `--max-turns`** in print mode to prevent runaway loops. Start with 5-10 for most tasks.
+2. **Use `--max-budget-usd`** for cost caps. Note: minimum ~$0.05 for system prompt cache creation.
+3. **Use `--effort low`** for simple tasks (faster, cheaper). `high` or `max` for complex reasoning.
+4. **Use `--bare`** for CI/scripting to skip plugin/hook discovery overhead.
+5. **Use `--allowedTools`** to restrict to only what's needed (e.g., `Read` only for reviews).
+6. **Use `/compact`** in interactive sessions when context gets large.
+7. **Pipe input** instead of having Claude read files when you just need analysis of known content.
+8. **Use `--model haiku`** for simple tasks (cheaper) and `--model opus` for complex multi-step work.
+9. **Use `--fallback-model haiku`** in print mode to gracefully handle model overload.
+10. **Start new sessions for distinct tasks** — sessions last 5 hours; fresh context is more efficient.
+11. **Use `--no-session-persistence`** in CI to avoid accumulating saved sessions on disk.
+
+## Pitfalls & Gotchas
+
+1. **Interactive mode REQUIRES tmux** — Claude Code is a full TUI app. Using `pty=true` alone in Hermes terminal works but tmux gives you `capture-pane` for monitoring and `send-keys` for input, which is essential for orchestration.
+2. **`--dangerously-skip-permissions` dialog defaults to "No, exit"** — you must send Down then Enter to accept. Print mode (`-p`) skips this entirely.
+3. **`--max-budget-usd` minimum is ~$0.05** — system prompt cache creation alone costs this much. Setting lower will error immediately.
+4. **`--max-turns` is print-mode only** — ignored in interactive sessions.
+5. **Claude may use `python` instead of `python3`** — on systems without a `python` symlink, Claude's bash commands will fail on first try but it self-corrects.
+6. **Session resumption requires same directory** — `--continue` finds the most recent session for the current working directory.
+7. **`--json-schema` needs enough `--max-turns`** — Claude must read files before producing structured output, which takes multiple turns.
+8. **Trust dialog only appears once per directory** — first-time only, then cached.
+9. **Background tmux sessions persist** — always clean up with `tmux kill-session -t <name>` when done.
+10. **Slash commands (like `/commit`) only work in interactive mode** — in `-p` mode, describe the task in natural language instead.
+11. **`--bare` skips OAuth** — requires `ANTHROPIC_API_KEY` env var or an `apiKeyHelper` in settings.
+12. **Context degradation is real** — AI output quality measurably degrades above 70% context window usage. Monitor with `/context` and proactively `/compact`.
+
+## Rules for Hermes Agents
+
+1. **Prefer print mode (`-p`) for single tasks** — cleaner, no dialog handling, structured output
+2. **Use tmux for multi-turn interactive work** — the only reliable way to orchestrate the TUI
+3. **Always set `workdir`** — keep Claude focused on the right project directory
+4. **Set `--max-turns` in print mode** — prevents infinite loops and runaway costs
+5. **Monitor tmux sessions** — use `tmux capture-pane -t <session> -p -S -50` to check progress
+6. **Look for the `❯` prompt** — indicates Claude is waiting for input (done or asking a question)
+7. **Clean up tmux sessions** — kill them when done to avoid resource leaks
+8. **Report results to user** — after completion, summarize what Claude did and what changed
+9. **Don't kill slow sessions** — Claude may be doing multi-step work; check progress instead
+10. **Use `--allowedTools`** — restrict capabilities to what the task actually needs
