Agents can edit beats, threads and tidbits, run structure checks and fit story arcs. [Open sandhi.naklitechie.com](https://sandhi.naklitechie.com/) ## Ask an agent to - Start a new story from my Story Spine lines - Run structure checks on my story and list next steps - Add a plant-and-payoff thread between beats 2 and 7 ## 48 tools - `sandhi.arc` Pearson fit of the fortune line against the six arcs (Reagan et al. 2016); best shape and every score. - `sandhi.beat.add` Insert a beat after the beat with id \`after\` (default: at the end).

Undo restores them. id: string - `sandhi.beat.update` Change fields of one beat: label, spine, joint (into this beat), text, fortune, tags, marks, driver, avastha, kis, drafts. Arrays replace whole. Undo reverses it. id: string, patch: object - `sandhi.chapter.start` Start a chapter at a beat: the name goes on that beat and on the beats after it, up to the next beat that already starts or belongs to another chapter.

The story does not change. text: string - `sandhi.read.run` Read a story (prose) with the chosen rung and stage a proposed structure; the story does not change. Beats are the writer's own text cut at the model's exact quotes; quotes not found in the text are dropped.

Proposals only; placing one is tidbit.update {placed}. It uses the… - `sandhi.write.plot` Ask the chosen reader how the structure changes around a new plot element: up to 6 changes, each a new empty beat (its stage, joint, fortune and a one-line label) or a relabel of an existing beat's stage, joint or… element: string - `sandhi.write.questions` Ask the chosen reader 2 to 4 questions about one beat, each from a principle the beat does least for.
