# Cline CLI Provider Configuration (Multi-Provider, Tier 2)
# Shell-sourceable config for loki-mode multi-provider support

# Provider Functions (for external use)
# =====================================
# These functions provide a clean interface for external scripts:
#   provider_detect()           - Check if CLI is installed
#   provider_version()          - Get CLI version
#   provider_invoke()           - Invoke with prompt (autonomous mode)
#   provider_invoke_with_tier() - Invoke with tier-specific model selection
#   provider_get_tier_param()   - Map tier name to model name
#
# Usage:
#   source providers/cline.sh
#   if provider_detect; then
#       provider_invoke "Your prompt here"
#   fi
#
# Note: autonomy/run.sh uses inline invocation for streaming support
# and real-time agent tracking. These functions are intended for
# simpler scripts, wrappers, and external integrations.

# Cline supports 12+ providers; model configured via LOKI_CLINE_MODEL env var
# or `cline auth` one-time setup. Defaults are placeholders.
# NOTE: Cline uses its own model routing, so full model strings are needed (not CLI aliases)
# Cline default model -- reads from providers/model_catalog.json via models.sh when
# available so new model releases only require updating that single catalog file.
