Plot Structure

Overview

Plan and manage story arcs, plot points, foreshadowing, and narrative timeline. Each arc is a markdown file in `plot/arcs/` with a chronological timeline maintained in `plot/timeline.md`. The plot index tracks all arcs, their status, and theme coverage.

Prerequisites

A story project must already exist (created via the story-init skill). Verify by checking for `story.md` in the project root.

Choosing a Story Structure

1. Read `story.md` for genre and themes 2. Consult `references/structure-models.md` for available structures 3. Recommend a structure based on genre (default to three-act if unclear) 4. Update `plot/_index.md` frontmatter `structure` field 5. Populate the story structure section with the beat sheet 6. When CLI access is available, run `story validate .`

Creating an Arc

1. Read `story.md` for themes 2. Read `plot/_index.md` for existing arcs 3. Read `characters/_index.md` to understand available characters 4. Ask for:

• Arc name
• Type (main, subplot, character, thematic)
• Which characters are involved
• Which themes it serves

5. Build the arc through conversation: setup, escalations, climax, resolution 6. Write the file using `references/arc-template.md` 7. Save to `plot/arcs/{arc-name-kebab}.md` 8. Update `plot/_index.md` arcs table 9. Update theme tracking in `plot/_index.md` 10. If characters are referenced, verify they exist in `characters/` 11. When CLI access is available, run `story reindex .`, `story links .`, and `story validate .`

Managing Plot Points

Plot points live within arc files in the "Plot Points" table. When adding a plot point:

1. Read the relevant arc file 2. Add the plot point to the table with chapter reference (if known) 3. Add the event to `plot/timeline.md` in chronological order 4. If the plot point involves foreshadowing, add it to the arc's foreshadowing table 5. If the plot point creates a reader promise or mystery, create or update a record in `continuity/promises/` or `continuity/questions/` 6. When CLI access is available, run `story validate .`

Timeline Management

The timeline at `plot/timeline.md` is a chronological master list of all story events across all arcs.

When adding events:

• Insert in chronological order
• Link to the relevant arc and chapter
• Keep entries concise (one line per event)

When reviewing the timeline:

• Check for chronological consistency
• Identify pacing issues (too many events clustered, long gaps)
• Flag arcs that haven't progressed

Foreshadowing Tracking

Each arc tracks its own foreshadowing in the "Foreshadowing" table:

• **Planted:** What hint or setup is placed
• **Payoff:** What the payoff will be
• **Chapter Planted / Chapter Payoff:** Where each occurs
• **Status:** `planned`, `planted`, or `paid-off`

During chapter writing, flag any `planted` items that haven't been paid off as reminders.

For durable cross-arc setup/payoff tracking, also maintain `continuity/promises/{promise-kebab}.md` with `status`, `planted`, `payoff`, `arcs`, and `characters`. For mystery or open-continuity tracking, maintain `continuity/questions/{question-kebab}.md`.

Cross-Referencing

• Arcs reference characters via frontmatter `characters` field
• Arcs reference themes via frontmatter `themes` field
• Plot points reference chapters
• Timeline entries link arcs and chapters
• Theme tracking in `plot/_index.md` maps themes to arcs and chapters
• Promises and questions reference chapters, arcs, and characters where relevant

CLI Maintenance

Use the Story CLI when it is available. If `story` is not installed but the `story-maintenance` skill is present, use `node ../story-maintenance/scripts/story.js` with the same arguments, resolving the path relative to this skill folder. If no CLI is available, perform the registry and backlink checks manually.

Reference Files

• **`references/arc-template.md`** - Template for arc files with frontmatter and sections
• **`references/question-template.md`** - Template for continuity questions and mysteries
• **`references/promise-template.md`** - Template for setup/payoff tracking
• **`references/structure-models.md`** - Story structure models (three-act, hero's journey, save the cat, kishotenketsu, five-act) with beat sheets
