Maximum-efficiency onboarding command. Single-command path for the user:
pip install sibyl-memory-cli
sibyl setup # auto-detects Hermes + Claude Code, prompts per stack, wires
Two wirers in v0.1.4:
- HermesWirer: install-plugin + edit $HERMES_HOME/config.yaml (memory.provider)
- ClaudeCodeWirer: edit ~/.claude/settings.json (mcpServers.sibyl-memory)
Each wirer follows the same protocol:
is_present() -> bool (filesystem + PATH detect)
current_state() -> dict (configured? wired-with-sibyl? current-value?)
wire(force, dry_run, prompt_fn) -> WireOutcome
Destructive operations (overwriting an existing non-SIBYL config) default to NO
on the prompt. Fresh adds default to YES. --force overrides destructive guards.
--yes accepts all defaults (still respects the destructive-default-NO unless
--force is also passed). --dry-run prints intent without writing.
All config edits are atomic: backup to <file>.bak, write to <file>.tmp, rename.
