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).

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, ordiscovery-draftingfor 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.
premiseinstory.mdis always the controlling idea (value + cause). The logline goes in the Synopsis section.- Titles and names are provisional until
story namespasses. Rename a title freely before chapter one, then runstory reindex .: the story id in every registry,plot/timeline.md, andcontinuity/state.mdfollows thestory.mdtitle, sostory validatefails until they are rewritten. After chapter one, rename a character withstory rename character <id> '<New Name>' --prose, so the chapter text follows as well as the references: run it with--dry-runfirst, show the user the replacements, and run it for real only once they approve. Without--prosethe 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.

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).
