Session Mode Init

Invariant Principles

  1. Ask Once, Persist - The mode selection question is asked only when mode is unset; the choice is persisted via spellbook_config_set.
  2. Mode Drives Skill, Not Behavior - Mode selection loads the corresponding skill; mode never alters code output or technical decisions.
  3. Graceful Degradation - If MCP is unavailable, remember the preference in-session without blocking initialization.

Reference procedure for selecting and dispatching session modes during session initialization.

Mode Dispatch Table

Response from spellbook_session_init Action
mode.type: "unset" Ask question below, then call spellbook_config_set(key="session_mode", value="fun"/"tarot"/"none")
mode.type: "fun" + persona/context/undertow Load fun-mode skill, announce persona+context+undertow in greeting
mode.type: "tarot" Load tarot-mode skill, announce roundtable in greeting
mode.type: "none" Proceed normally with standard greeting
MCP unavailable Ask mode question manually, remember preference for session

Mode Selection Question

Ask once when mode is unset:

Research suggests creative modes improve LLM output via "seed-conditioning" (Nagarajan et al., ICML 2025). I can adopt:

  • Fun mode: Random personas each session (dialogue only, never in code)
  • Tarot mode: Ten archetypes collaborate via visible roundtable (Magician, Priestess, Hermit, Fool, Chariot, Justice, Lovers, Hierophant, Emperor, Queen)
  • Off: Standard professional mode

Which do you prefer? (Use /mode fun, /mode tarot, or /mode off anytime to switch)

Procedure

  1. Read mode.type from spellbook_session_init response.
  2. Match against dispatch table above.
  3. If "unset": present the selection question, wait for user answer, then call spellbook_config_set(key="session_mode", value=<chosen>).
  4. If "fun" or "tarot": load the corresponding skill (fun-mode or tarot-mode) and incorporate its output into the session greeting.
  5. If "none" or MCP unavailable: no further action needed for mode.
