Guides stable API and interface design. Use when designing APIs, module boundaries, or any public interface. Use when creating REST or GraphQL endpoints, defining type contracts between modules, or establishing boundaries between frontend and backend.
Tests in real browsers. Use when building or debugging anything that runs in a browser. Use when you need to inspect the DOM, capture console errors, analyze network requests, profile performance, or verify visual output with real runtime data via Chrome DevTools MCP.
Automates CI/CD pipeline setup. Use when setting up or modifying build and deployment pipelines. Use when you need to automate quality gates, configure test runners in CI, or establish deployment strategies.
Conducts multi-axis code review. Use before merging any change. Use when reviewing code written by yourself, another agent, or a human. Use when you need to assess code quality across multiple dimensions before it enters the main branch.
Simplifies code for clarity. Use when refactoring code for clarity without changing behavior. Use when code works but is harder to read, maintain, or extend than it should be. Use when reviewing code that has accumulated unnecessary complexity.
Optimizes agent context setup. Use when starting a new session, when agent output quality degrades, when switching between tasks, or when you need to configure rules files and context for a project.

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.
npm install -g @anthropic-ai/claude-codeclaude once to log in (browser OAuth for Pro/Max, or set ANTHROPIC_API_KEY)claude auth login --console for API key billingclaude auth login --sso for Enterpriseclaude auth status (JSON) or claude auth status --text (human-readable)claude doctor — checks auto-updater and installation healthclaude --version (requires v2.x+)claude update or claude upgradeHermes interacts with Claude Code in two fundamentally different ways. Choose based on the task.
-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:
--json-schemacat file | claude -p "analyze this")Print mode skips ALL interactive dialogs — no workspace trust prompt, no permission confirmations. This makes it ideal for automation.
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:
/compact, /review, /model)Claude Code presents up to two confirmation dialogs on first launch. You MUST handle these via tmux send-keys:
❯ 1. Yes, I trust this folder ← DEFAULT (just press Enter)
2. No, exit
Handling: tmux send-keys -t <session> Enter — default selection is correct.
❯ 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
# 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.

claude -c | Continue the most recent conversation in this directory |
claude -r "id" | Resume a specific session by ID or name |
claude auth login | Sign in (add --console for API billing, --sso for Enterprise) |
claude auth status | Check login status (returns JSON; --text for human-readable) |
claude mcp add <name> -- <cmd> | Add an MCP server |
claude mcp list | List configured MCP servers |
claude mcp remove <name> | Remove an MCP server |
claude agents | List configured agents |
claude doctor | Run health checks on installation and auto-updater |

claude auto-mode | Inspect auto mode classifier configuration |
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).
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).
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.
# 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)
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.
# 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)
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).

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.
Unlike slash commands (manually invoked), skills in .claude/skills/ are markdown guides that Claude invokes automatically via natural language when the task matches:

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.
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 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 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.
For projects with many rules, use the rules directory instead of one massive CLAUDE.md:
.claude/rules/*.md — team-shared, git-tracked~/.claude/rules/*.md — personal, globalEach .md file in the rules directory is loaded as additional context. This is cleaner than cramming everything into a single CLAUDE.md.
Claude automatically stores learned project context in ~/.claude/projects/<project>/memory/.
Define specialized agents in .claude/agents/ (project), ~/.claude/agents/ (personal), or via --agents CLI flag (session):
.claude/agents/ — project-level, team-shared--agents CLI flag — session-specific, dynamic~/.claude/agents/ — user-level, personal# .claude/agents/security-reviewer.md
