Multi-turn conversation with Heista's creative direction engine — a real chat where the agent decides each turn what to produce based on what you ask for. Use whenever the work needs more than one round, OR when you want an output shape not covered by call_creative_worlds' `medium` enum.
WHAT YOU CAN ASK FOR (any of these, turn 1 or any turn after):
• Territories — "give me five directions for X", "what angles work here"
• A TVC script — "write a 30-second TVC for Cowboys"
• Billboard concepts — "three billboards under a quiet-authority lens"
• A campaign platform — "build #2 into a full campaign with the big idea"
• A manifesto or copy — "draft the manifesto in the brand voice"
• Naming — "name this product, five options with rationale"
• A PR stunt — "what's the newsworthy version of this"
• A content series — "20 episode ideas for a brand podcast"
• Packaging, sonic branding, partnerships, social systems
• Refinement — "make #2 darker", "extend that into a tagline", "summarise"
• Pivots — "forget the soft-drink angle, try the late-night insomnia one"
SESSION: omit session_id on turn 1; the response returns a fresh session_id you pass on every subsequent turn — that is how the conversation persists. brand_id is only honoured on turn 1 of a new session (continuing sessions keep their original brand context).
USE WHEN: user wants back-and-forth, OR wants an output shape outside the medium enum (manifesto, naming, press release, content series, packaging, etc.). Prefer call_creative_worlds when the user wants "three options, done" with no follow-up.
WON'T DO: write OKRs / internal docs / strategy decks; behave as a general assistant. It is a creative director with creative-director taste — anti-cliché, specificity test, will push back on vague briefs.
Metered — typically 2-10 credits per turn depending on tool use and context size. Charged after each turn on actual token usage.
