Claude Code Headless Mode

Run Claude Code from scripts without interactive UI.

Quick Start

# Basic headless execution
claude -p "Explain this code" --allowedTools "Read,Grep"

# JSON output for parsing
claude -p "List files" --output-format json

# Continue conversation
claude -p "Start analysis" --output-format json > result.json
session=$(jq -r '.session_id' result.json)
claude --resume "$session" "Now fix the issues"

Essential CLI Options

Flag	Description
`-p`, `--print`	Non-interactive (headless) mode
`--output-format`	text, json, stream-json
`-r`, `--resume`	Resume by session ID
`-c`, `--continue`	Continue most recent session
`--allowedTools`	Comma-separated allowed tools
`--disallowedTools`	Comma-separated denied tools
`--mcp-config`	Path to MCP server config JSON
`--verbose`	Enable verbose logging
`--append-system-prompt`	Add to system prompt

Permission Modes

Mode	Flag	Effect
Default	(none)	Prompt for permissions
Accept edits	`--permission-mode acceptEdits`	Auto-accept file changes
Bypass	`--permission-mode bypassPermissions`	Skip all prompts

Output Formats

Text (default)

claude -p "Hello"
# Outputs: Human-readable response

JSON

claude -p "Hello" --output-format json

{
  "type": "result",
  "subtype": "success",
  "result": "Hello! How can I help?",
  "session_id": "abc123",
  "total_cost_usd": 0.001,
  "duration_ms": 1234,
  "num_turns": 1
}

Stream-JSON

claude -p "Hello" --output-format stream-json
# Real-time JSONL output for each message

Common Patterns

Script with tool restrictions

claude -p "Analyze the codebase" \
  --allowedTools "Read,Grep,Glob" \
  --disallowedTools "Write,Edit,Bash"

CI/CD integration

claude -p "Review this PR diff" \
  --permission-mode acceptEdits \
  --output-format json \
  --append-system-prompt "Focus on security issues"

Multi-turn automation

session=$(claude -p "Start task" --output-format json | jq -r '.session_id')
claude --resume "$session" "Continue with step 2"
claude --resume "$session" "Finalize and report"

Error Handling

result=$(claude -p "Task" --output-format json)
if [[ $(echo "$result" | jq -r '.is_error') == "true" ]]; then
    echo "Error: $(echo "$result" | jq -r '.result')" >&2
    exit 1
fi

概要と使いどころ

acquisition-policy-workflow

無料

Trigger for: explaining current FAR, DFARS, or agency-supplement text; determining documented acquisition-policy status for an agency and FAR part; comparing codified text, RFO model text, and agency deviations; tracing acquisition rulemaking; finding procurement comment periods; analyzing public comments; refreshing prior policy analysis; or producing an Acquisition Policy Impact Brief. Use published federal sources and supplied policy documents without making legal or procurement-specific applicability determinations. Do not use for clause selection, market research execution, opportunities, pricing, grants, or cooperative agreements.
