Claude Code — Hermes Orchestration Guide

Delegate coding tasks to Claude Code (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)

⚠️ Auth Mode Matters: Three Paths

This is the #1 gotcha with Claude Code v2. There are three auth paths:

Recommended for Hermes agents: SDK + OAuth path.

# claude_agent_sdk is pre-installed at /usr/local/lib/python3.13/site-packages
from claude_agent_sdk import ClaudeAgentOptions, ClaudeSDKClient
import asyncio

async def delegate(task):
    # CRITICAL: Remove ANTHROPIC_API_KEY from env so SDK uses OAuth from ~/.claude/.credentials.json
    import os
    env = os.environ.copy()
    env.pop("ANTHROPIC_API_KEY", None)
    os.environ.update(env)
    
    options = ClaudeAgentOptions(
        model="sonnet",                    # Always use sonnet per user preference
        permission_mode="bypassPermissions",  # Auto-approve all tools
        cwd="/path/to/project",
    )
    async with ClaudeSDKClient(options=options) as client:
        await client.query(task)
        async for msg in client.receive_response():
            if hasattr(msg, "content") and msg.content:
                for block in msg.content:
                    if hasattr(block, "text") and block.text:
                        print(block.text)

Gotcha: If ANTHROPIC_API_KEY is set in the inherited environment (e.g., from a parent shell that ran claude auth login), it will be set to the OAuth access token which is NOT a valid API key. The SDK then fails with HTTP 401. Always unset ANTHROPIC_API_KEY before using the SDK with OAuth.

Cross-user issue: Credentials are stored in $HOME/.claude/.credentials.json. If the agent runs as a different user than the one who logged in, copy the credentials file and chown it.

User preference (explicit): Always execute Claude Code with --model sonnet --dangerously-skip-permissions. In SDK terms: model="sonnet", permission_mode="bypassPermissions". Delegate all logic-heavy coding tasks to Claude Code — the agent should only do simple one-liner edits directly.

• 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.

CLI Subcommands

Hermes SDK Integration (PREFERRED)

The claude-agent-sdk Python package provides direct programmatic access to Claude Code. This is the preferred integration method for Hermes agents — no PTY, no tmux, no remote-control needed. It uses your existing OAuth credentials automatically.

Prerequisites

• claude-agent-sdk Python package (check: pip show claude-agent-sdk)
• OAuth credentials in ~/.claude/.credentials.json (from claude auth login)
• CRITICAL: The ANTHROPIC_API_KEY env var must NOT be set — it overrides OAuth. The OAuth token in the credentials file is NOT a valid Anthropic API key. Unset it: unset ANTHROPIC_API_KEY

Quick Test

unset ANTHROPIC_API_KEY && export HOME=/data && cd /project && python3 -c "
from claude_agent_sdk import ClaudeAgentOptions, ClaudeSDKClient
import asyncio

async def main():
    options = ClaudeAgentOptions(
        model='sonnet',
        permission_mode='bypassPermissions',
        cwd='/project',
    )
    async with ClaudeSDKClient(options=options) as client:
        await client.query('Reply with exactly: SDK_READY')
        async for msg in client.receive_response():
            if hasattr(msg, 'content'):
                for block in msg.content:
                    if hasattr(block, 'text'):
                        print(block.text)

asyncio.run(main())
"

If this prints SDK_READY, the integration works.

Persistent Wrapper (Recommended)

Use the wrapper script at /data/workspace/perp-trading-bot/scripts/claude_delegate.py:

cd /data/workspace/perp-trading-bot
python3 scripts/claude_delegate.py "Add error handling to src/risk_engine.py"
python3 scripts/claude_delegate.py --file /tmp/task.txt
echo "Task description" | python3 scripts/claude_delegate.py --stdin
python3 scripts/claude_delegate.py "Refactor" --model sonnet

The wrapper handles environment cleanup (unsetting ANTHROPIC_API_KEY, setting HOME, etc.).

For Delegation via delegate_task

When spawning a coding subagent with delegate_task, pass the SDK-based wrapper:

goal: "Delegate this coding task to Claude Code using the SDK wrapper"
context: |
  Run this command to complete the task:
  cd /data/workspace/perp-trading-bot && python3 scripts/claude_delegate.py "THE TASK"
  
  The wrapper uses Claude Code v2 via the claude-agent-sdk with:
  - model: sonnet
  - permission_mode: bypassPermissions
  - tools: Read, Write, Edit, Bash, Glob, Grep, Task
  - auth: OAuth from ~/.claude/.credentials.json

Why Not Other Methods?

Always Use

• Model: sonnet (as specified by user)
• Permission mode: bypassPermissions (maps to --dangerously-skip-permissions)
• Clear ANTHROPIC_API_KEY from environment before launching

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:

{
  "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:

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).

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

{
  "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.

Development & Review

Configuration & Tools

Custom Slash Commands

Create .claude/commands/<name>.md (project-shared) or ~/.claude/commands/<name>.md (personal):

# .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:

# .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

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:

# 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

# .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):

{
  "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"}]
    }]
  }
}

  }]
}

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

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

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.
13. Auth status may differ between sessions — claude auth status can show loggedIn: false from the agent's process even when the user authenticated from their shell. Credentials may be stored in a different home directory or env context. See references/claude-code-auth-troubleshooting.md for diagnosis steps.
14. Tmux server won't persist in Docker — tmux start-server and tmux new-session -d fail silently in Docker containers because the server daemonizes and loses its parent process. Use the claude-agent-sdk Python library instead for programmatic delegation — it handles PTY creation internally and works reliably in containers.
15. claude remote-control requires workspace trust — The remote-control server checks for workspace trust before starting. Trust is a TUI-only interaction that cannot be automated from a non-interactive process in Docker. Use the claude-agent-sdk instead, which bypasses the trust check entirely.
16. SDK + OAuth is the recommended agent path — The claude-agent-sdk (v0.2.87, pre-installed at /usr/local/lib/python3.13/site-packages) provides ClaudeSDKClient with query() and receive_response(). It works with OAuth credentials when ANTHROPIC_API_KEY is unset. This is more reliable than tmux orchestration or print mode for agent-to-agent delegation.

2. Always unset ANTHROPIC_API_KEY before using the SDK — Required for OAuth to work; see references/claude-agent-sdk-delegation.md.
3. Prefer print mode (-p) only when API key is explicitly set — Otherwise use SDK.
4. Use tmux for multi-turn interactive work — but note: tmux does not persist in Docker containers (pitfall #14).
5. Always set workdir — keep Claude focused on the right project directory.
6. Set --max-turns in print mode — prevents infinite loops and runaway costs.
7. Report results to user — after completion, summarize what Claude did and what changed.
8. Don't kill slow sessions — Claude may be doing multi-step work; check progress instead.
9. Use --allowedTools — restrict capabilities to what the task actually needs.
