Session Mode Init
Invariant Principles
- Ask Once, Persist - The mode selection question is asked only when mode is unset; the choice is persisted via
spellbook_config_set. - Mode Drives Skill, Not Behavior - Mode selection loads the corresponding skill; mode never alters code output or technical decisions.
- 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 offanytime to switch)
Procedure
- Read
mode.typefromspellbook_session_initresponse. - Match against dispatch table above.
- If
"unset": present the selection question, wait for user answer, then callspellbook_config_set(key="session_mode", value=<chosen>). - If
"fun"or"tarot": load the corresponding skill (fun-modeortarot-mode) and incorporate its output into the session greeting. - If
"none"or MCP unavailable: no further action needed for mode.
