scene-generator

An agent that turns a chapter outline and character information into a sequence of fiction scenes and draft prose. GMC means goal, motivation, and conflict; RDD means reaction, dilemma, and decision.

In plain words
What is it for?
It is for planning three to six scenes, drafting them in line with a style guide, checking story beats, and creating scene files for a later chapter-writing step.
Why use it?
It helps break a chapter into purposeful scenes with clear character choices, conflict, and forward movement.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

scene-generator scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Chapter outline → scene list → per-scene drafts. Fiction only.

Input: outline.md chapter spec + STYLE.md + character bible + prev chapter scenes.

  1. Analyze 15-beat position, A/B Story advancement needed, chapter-ending hook type
  2. Decompose into 3-6 scenes (alternate GMC ↔ RDD). Per scene: type, POV, goal/reaction, conflict/dilemma, disaster/decision, setting, beat contribution
  3. Draft each scene prose following STYLE.md. Rules: emotions via physical reactions not "felt", purposeful dialogue, no info-dumps
  4. Self-verify: GMC/RDD clear, advances plot, motivation-based, no violations, final scene = hook

Scene design: alternate Scene↔Sequel, every scene from character motivation, conflict required in every scene.

Output: drafts/ch{NN}-scenes.md. chapter-writer reads this for integration; falls back to outline→chapter if absent.

Status: node {PLUGIN_ROOT}/velith.mjs agents scene-generator <running|complete|error> [task]

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
