Interactive shell

$ sellfun
  ┌─────────────────────────────┐

  └─────────────────────────────┘

The shell supports command history (up/down arrows), tab completion, and inline results.

Authentication

sellfun login                    # Browser-based (recommended)
sellfun login --token <token>    # Direct token (CI/CD)
SELLFUN_TOKEN=... sellfun list   # Environment variable

Configuration

Config is stored at ~/.sellfun/config.json (mode 0600).

Agent / CI Usage

The CLI works fully non-interactively for AI agents and CI/CD pipelines:

# Create + publish in one command
SELLFUN_TOKEN=tok sellfun create \
  --title "AI Weather Skill" \
  --description "Real-time weather for 200+ cities" \
  --price 4.99 \
  --url "https://example.com/weather.zip" \
  --publish --format json

# Preview without executing
sellfun create --title "Test" --price 1.99 --url "https://..." --dry-run --format json

# Structured error output
# { "ok": false, "error": { "code": "AUTH_EXPIRED", "message": "..." } }

Non-interactive mode activates when stdin is not a TTY, CI=true, or SELLFUN_NON_INTERACTIVE=1.

See CONTEXT.md for the full agent reference and skills/ for workflow guides.

Telemetry

Optional, opt-in crash reporting. Disabled by default.

sellfun telemetry status   # Check setting
sellfun telemetry on       # Enable anonymous crash reports
sellfun telemetry off      # Disable

Respects DO_NOT_TRACK=1 and SELLFUN_TELEMETRY=0 environment variables.
