Elephant Copilot Provider

Custom Elephant provider that uses GitHub Copilot CLI to answer questions and surface commands inside Walker.

Features

• Q&A via copilot -p (standalone) or gh copilot -- -p (wrapper)
• Model selection (configurable list)
• Command extraction (code fences + $ / > prompt lines)
• Copy answer and copy command actions
• Copy all extracted commands
• Open new terminal with a prefilled command (not executed)
• Temporary and persistent sessions

Build

go build -buildmode=plugin -o build/copilot.so

Install

mkdir -p ~/.config/elephant/providers
cp build/copilot.so ~/.config/elephant/providers/

Configuration

Create ~/.config/elephant/copilot.toml:

enabled = true
cli_mode = "both" # auto|copilot|gh|both
default_model = "claude-sonnet-4.5"
models = [
  "claude-sonnet-4.5",
  "gpt-5.2-codex",
  "gpt-4.1",
]

# CLI args
copilot_args = ["--no-color", "--silent"]
gh_copilot_args = ["--no-color", "--silent"]

# Session storage (defaults to XDG_STATE_HOME/elephant/copilot)
# session_dir = "/home/user/.local/state/elephant/copilot"

# Clipboard and terminal integration
clipboard_cmd = "wl-copy"
terminal_prefill_cmd = "bash -lc 'read -e -i %CMD% -p \">>> \" cmd; exec $SHELL'"

# Optional command extraction override
# command_extract_regex = "(?m)^\\$\\s+(.+)$"

Walker Integration

Add copilot to Walker providers (installed + prefixed, but not default). See the dotfiles integration scripts for the exact config changes.

Notes

• The provider is opt-in: enabled defaults to false.
• The terminal_prefill_cmd uses %CMD% as a placeholder and is shell-escaped.
