premise-workshop

This skill should be used when the user asks to "brainstorm a story idea", "I have an idea for a story", "what if", "develop a premise", "is this idea strong enough", "workshop my logline", "premise", "story concept", "what should I write", "short story or novel", "novella or novel", "name my book", "title ideas", or has a spark (an image, a character, a setting, a question) and wants to turn it into a tested premise before starting a story project. NOT for the controlling idea or theme of an existing story (use theme-craft).

Is this agent skill safe to install?

  • Gen Agent Trust Hubpass

    The skill is a story development tool that uses a CLI to manage project metadata. It incorporates user-provided story ideas into shell commands, which presents a surface for indirect prompt injection. However, the skill explicitly provides sanitization instructions to mitigate this risk.

What does this agent skill do?

Premise Workshop

Overview

Turn a spark into a premise that can carry a book, before story init builds the project. The workshop generates what-ifs from the spark, tests them as loglines, drafts the controlling idea and its counter-argument (premise and counter-premise in story.md), names the stakes, chooses a form (the form field), brainstorms titles, sanity-checks the idea against comparable books, and hands a filled-in brief to the story-init skill. The author owns the idea: offer options and tests, never decide for them.

Prerequisites

None. The workshop usually runs before a project exists. If the user wants the work saved before story init, keep it in one premise-notes.md file in the current directory (outside the future project folder) and move the kept material into story.md after init.

When to Use

  • The user has a spark but no premise, or several ideas and cannot choose
  • The user has a premise and wants to know whether it holds up
  • Choosing between short story, novella, novel, serial, or a children's form
  • Brainstorming a title, or checking a working title against the cast
  • NOT for creating the project folder (use story-init; this skill hands off to it)
  • NOT for refining the controlling idea of a drafted book, arc types, or the lie/truth machinery (use theme-craft)
  • NOT for outlining once the premise is settled (use plot-structure, or discovery-drafting for pantsers)
  • NOT for comp titles, pitch, or blurb for submission (use submission)

Workflow

1. Capture the spark

Ask what the user has, in their words, and do not improve it yet. Ask which language the book will be written in if it is not clear, and workshop in that language: what-ifs, loglines, and titles are drafted in it, and comps come from the market that reads it. Sort it: an image (a drowned bell tower), a what-if (what if grief could be sold), a character (a lighthouse keeper who has never left the rock), a setting (a city that moves every winter), or a feeling they want a reader to have. Ask what drew them to it. The answer is often the book's real subject and should survive every later change.

2. Generate what-ifs

Following references/what-if-generation.md, produce 8-12 short what-ifs from the spark across different angles (invert it, raise the cost, move it in time or place, give it to the wrong person). Present them as a numbered list and ask the user to pick one to three, or to combine. Do not rank them for the user unless asked; do say which ones already imply conflict.

3. Workshop the logline

For each chosen what-if, draft a logline with the recipe in ../story-init/references/title-logline.md (protagonist + want + obstacle

  • stakes). Then run every logline stress test in references/premise-tests.md. Report each test as pass, weak, or fail with one sentence of why, and offer one revision per weak or failed test.

4. Draft premise and counter-premise

story.md's premise field is the controlling idea (value + cause), not the logline. Draft it and the counter-premise as working hypotheses using ../theme-craft/references/controlling-idea.md. If the user wants to discover theme in the draft, record premise: tbd-discovery and move on. Keep the logline for the Synopsis section.

5. Name the stakes

Write the stakes on three levels (see references/premise-tests.md): external (what is lost in the world), relational (who is lost or betrayed), and internal (what the protagonist becomes if they fail). At least two levels must be concrete and personal.

6. Choose the form

Use references/form-choice.md to match the idea's scope to a form: novel, novella, novelette, short-story, flash, serial, picture-book, or chapter-book. Count the idea's moving parts (POV characters, threads, locations, time span) and recommend the form they fit, with the trade-offs. The user decides.

7. Brainstorm titles

Follow references/title-and-comps.md: generate titles across the families listed there, cut to a shortlist of five, and test each against the logline and the genre shelf. The title craft principles live in ../story-init/references/title-logline.md; do not repeat them to the user, apply them.

Once a project exists, check title words and new names against the story's entities before adopting them:

story names 'Bell Tower' Bell 'Maren' --path .

An exact clash exits 1 and must be resolved; look-alike warnings and a shared initial with a major character are the user's call. Multi-word names are only checked for exact clashes, so pass a multi-word title's distinctive word separately, as Bell is above. The "Check names against the project" section of references/title-and-comps.md says what each finding means and how to resolve a clash.

8. Sanity-check against comparable books

Ask the user for two or three recent books the idea sits beside. Use references/title-and-comps.md to check whether the premise is distinct from them and whether it fits the shelf they imply. Never invent titles, authors, or sales claims; if web search is available, verify that each named book exists and note what you checked. If not, mark the list unverified.

9. Hand off to story-init

Present a one-screen brief: working title, logline, premise, counter-premise, stakes, form, genre and sub-genre, POV and tense if known, themes, the comps, and the book's language as a BCP 47 tag (en, fr, es-MX, ja). On approval, follow the story-init skill with the brief:

story init 'The Keeper of Skerry Light' --form novella --genre fantasy --sub-genre coastal --synopsis 'A lighthouse keeper who has never left the rock must choose between the light and her drowned brother.' --theme isolation

Workshop text is the user's own words, so wrap every value in single quotes before running the command. Never paste a value into double quotes, where $(...), backticks, and " still take effect. A single quote inside a value depends on the shell: write it as '\'' in a POSIX shell (bash, zsh, sh, Git Bash) and as '' in PowerShell. Never run the command in cmd.exe, which has no single quotes and runs & inside a value; use PowerShell or a POSIX shell.

--form sets form in story.md and a default target-words for the form when none is given (serial sets none; set per-episode chapter target-words instead). The form defaults and references/form-choice.md lengths are English word counts; for a book in another language, discuss the target with the user. A Chinese (zh) or Japanese (ja) book is counted in characters: talk about length in characters (10万字, or sheets of 400字 for Japanese), and once language is in story.md, replace target-words with target-characters (the story-init skill lists the per-form defaults). Then hand-edit premise, counter-premise, and language (the tag from the brief) into story.md, and move the stakes, rejected what-ifs worth keeping, title shortlist, and comps into its ## Notes section. Keep premise-notes.md if one was made: offer to move it into the new project as notes/premise-notes.md, and delete it only when the user asks after seeing what was carried over.

Conventions

  • Present options, not verdicts. The user chooses the what-if, form, and title; record why when they reject a recommendation.
  • Keep the spark's original wording in the notes. Premises drift during workshop; the spark is the check that the drift was chosen.
  • premise in story.md is always the controlling idea (value + cause). The logline goes in the Synopsis section.
  • Titles and names are provisional until story names passes. Rename a title freely before chapter one, then run story reindex .: the story id in every registry, plot/timeline.md, and continuity/state.md follows the story.md title, so story validate fails until they are rewritten. After chapter one, rename a character with story rename character <id> '<New Name>' --prose, so the chapter text follows as well as the references: run it with --dry-run first, show the user the replacements, and run it for real only once they approve. Without --prose the prose keeps the old name.
  • Never present a comparable title, author, prize, or market fact as verified without a source.

CLI Maintenance

Use the Story CLI when it is available. If story is not installed, use the bundled fallback node ../story-maintenance/scripts/story.js with the same arguments. Use node <checkout>/bin/story.js instead only when the user names a Story Skills repository checkout or you are working in one. Write the script as an absolute path (resolve the fallback relative to this skill folder) and run it from the folder you would run story from, so . and other relative paths keep their meaning. Use Node, not Bun or a package script: Bun would load that folder's bunfig.toml (which can run code) and .env, and a package script runs from the checkout's root. If no CLI is available, create the project by hand as the story-init skill describes and check names against the registries by reading them.

After story init and the hand edits to story.md:

story reindex .
story wordcount . --write
story check .
story report .

story check warns when target-words (target-characters for Chinese or Japanese) sits outside the chosen form's usual range; either adjust the target or confirm the choice with the user. story reindex . is needed only when the title changed, but it is safe to run every time.

Reference Files

  • references/what-if-generation.md - Angles for turning an image, character, setting, or question into conflict-bearing what-ifs, with worked examples
  • references/premise-tests.md - Logline stress tests, the three levels of stakes, and common premise failures with fixes
  • references/form-choice.md - Matching an idea's scope to a form: moving-parts count, what each form does well, and the form values
  • references/title-and-comps.md - Title brainstorming families, shortlist tests, story names checks, and the comparable-title sanity check

Shared Conventions

Every story skill follows the shared conventions in ../story-maintenance/references/conventions.md, resolved relative to this skill folder. Read it before creating, renaming, or linking story files. If that file is missing because this skill was installed without story-maintenance, the essentials are: kebab-case ids and filenames, YAML frontmatter on every story-project file, _index.md registry tables that story reindex rebuilds (never edit them by hand), bidirectional links between entities, characters for who is on the page and mentions for who is only referred to, status: deceased plus died-in: chapter-{NN} for deaths, and no project-local generator or build scripts (run only the installed or bundled Story CLI).

Add the canonical catalog link to the repository README so users can inspect current installs and available audits. The publishing guide covers the complete discovery path.
