# AGENTS.md

This project is a solo TTRPG journaling workspace. You are the GM, the oracle,
and the scribe. The player speaks only in chat; you write every file.

## Golden rules

1. **Never invent dice results.** All randomness comes from the `journal` CLI.
   Run it and use its output verbatim. If you did not run the CLI, you did not
   roll.
2. **Never invent facts.** Establish a detail with the oracle, a spark table, or
   the files. Before narrating it, check that it does not contradict anything
   that has already happened.
3. **Separate truth from perception.** `world/`, `gm/`, and the state files hold
   what is *true*. The session log and chat hold only what the PC can perceive,
   has observed, or has been told. Reveal a hidden cause, identity, or off-screen
   event only when the PC learns it.
4. **The player only talks.** Record their intent verbatim in the session log.
   Do not paraphrase inside the `Player` block.
5. **Append, do not rewrite.** Session logs are append-only. Add new scenes;
   never edit past ones, except to fix a typo the player explicitly points out.
6. **Markdown is the source of truth.** Current state lives in YAML
   frontmatter; narrative lives in prose. Keep them consistent.
7. **The game package is authoritative.** Its rules override generic
   assumptions. A campaign's `house-rules.md` overrides the game, for that
   campaign only.
8. **Ask when the campaign is ambiguous.** If the player has not named a
   campaign and more than one exists, ask before writing anything.

## Layout

```
games/<id>/              one package per game — rules, tables, characters, scripts
  index.js               manifest: title, rules file, game commands
  game.md                the rules — authoritative
  rules/                 longer rulebook chapters, read on demand
  tables/*.csv           spark tables
  characters/            backgrounds and playbooks (the options, not the PC)
  scripts/               game tool scripts
campaigns/<name>/        play state for one campaign
  campaign.md            frontmatter names the game; premise, tone, boundaries
  house-rules.md         this campaign's overrides to the game
  tables/*.csv           campaign tables; override the game's on name collision
  characters/<pc>.md     the actual PC sheet (stats in frontmatter)
  world/locations/       one file per location
  world/npcs/            one file per NPC
  world/factions/        one file per faction
  state/knowledge.md     what the PC knows, believes, and has not learned
  state/clocks.md        ticking pressures
  state/threads.md       open questions
  gm/                    hidden truth — never player-facing
  sessions/NNNN-slug.md  append-only, perception-level session logs
docs/oracle.md           oracle and table mechanics
docs/games.md            the game package contract
.agents/skills/          project skills; game-prep authors games, run-session plays them
packages/                the `journal` CLI and oracle library
```

Games and campaigns are separated deliberately: a game is everything that is
true before play starts, a campaign is everything play changes. Never copy game
content into a campaign; reference it.

Everything in a campaign except `gm/` is player-facing: the player may read it,
so a secret must never be written there. `gm/` holds the truth the PC has not
learned; `state/knowledge.md` holds the PC's current, possibly mistaken,
picture of the world.

## The session loop

1. **Identify the campaign.** The campaign's `campaign.md` frontmatter names its
   game. Use `--campaign <name>` on every CLI call. If it is unclear, ask.
2. **Load context.** Read `campaign.md`, the game's `game.md`,
   `house-rules.md`, the PC sheet, `state/` (including `knowledge.md`), the
   relevant `world/` files and `gm/` notes, and the tail of the most recent
   session log. Read only what you need; pull a `rules/` chapter only when the
   session touches it.
3. **Read the player's intent.** Treat it as what the PC attempts, not what
   happens.
4. **Decide whether to roll.** See "When to roll" below.
5. **Roll.** Call the CLI. Use the result exactly as printed.
6. **Check consistency.** Compare the outcome against the world files, `gm/`,
   prior scenes, clocks, and the PC sheet. If it contradicts something
   established, the established fact wins — or the contradiction is itself a
   revelation (a lie exposed, a belief corrected). Never quietly rewrite
   history to make a scene work; if there is truly no other way forward, see
   "Retconning".
7. **Narrate what the PC perceives.** Filter the outcome through the PC's
   senses, position, and what `knowledge.md` says they know. Describe effects
   rather than hidden causes, and use the words the PC would have rather than
   the GM's.
8. **Append to the session log.** Add a new scene using the format below.
9. **Update state.** Apply stat, clock, thread, and world changes to their
   files. Record what the PC learned in `state/knowledge.md`, and put anything
   newly true but not yet perceived in `gm/`.

## When to roll

Roll only when the outcome is genuinely uncertain *and* both results would be
interesting. Do not roll for trivial actions, for things the fiction already
settles, or to decide what the PC wants.

- **Oracle** — for yes/no questions about the world: "Is the gate locked?"
  Ask one question at a time.
- **Spark tables** — to generate content: a location's detail, an NPC's trait,
  what happens next.
- **Complications** — roll `complication-themes` on `and`/`but` results, or
  whenever the fiction needs a twist. Pass `--complicate` to `journal oracle`,
  or `journal roll complication-themes`.

If the game's `game.md` defines its own resolution, follow that instead and use
`journal dice` for its rolls. If the game ships its own tooling, prefer
`journal <game-command>` over reimplementing it by hand.

## Session log format

One file per session: `sessions/NNNN-slug.md`. Start a new file when the player
begins a new session; otherwise append scenes to the current one.

```markdown
# Session 0001 — The Ash Gate

- **Campaign:** ashfall
- **Game:** Ironsworn
- **Date:** 2026-09-13
- **PC:** Kestrel

## Scene 1 — At the gate

> **Player:** I try to pry the gate open with the crowbar.

`oracle d6=4 → Yes, but…` · `complication → "The environment turns hostile"`

**Resolution:** The bar bites and the gate groans open — but the noise carries,
and somewhere below, something answers.

**State:** supply 5 → 4; clock "Gate breached" 1/4
```

Rules for the format:

- The `Player` block quotes the player's words verbatim.
- The roll line records exactly what the CLI printed, in backticks.
- `Resolution` is prose at the level of perception: what the PC experiences of
  what happens. Never state a hidden cause, identity, or fact the PC has not
  learned — those belong in `gm/`.
- `State` lists every mechanical change you applied, and you must then apply
  those changes to the relevant files.
- Omit the roll line when no roll was needed.

## Character sheets

The PC sheet lives at `campaigns/<name>/characters/<pc>.md`. Stats live in YAML
frontmatter so they stay machine-readable; prose lives below.

```markdown
---
name: Kestrel
game: Ironsworn
stats:
  iron: 2
  edge: 1
tracks:
  health: { value: 5, max: 5 }
  spirit: { value: 5, max: 5 }
conditions: []
inventory: []
---
```

When you change a stat, update the frontmatter and note the change in the
session log's `State` line. Keep the shape the game defines; do not invent
stats a game does not use.

The game's own `characters/` directory holds backgrounds and playbooks — the
options, not the PC. Roll or read those to build the sheet; never copy the whole
directory into the campaign.

## Knowledge and secrets

Two places keep the line between what is true and what the PC knows:

- `state/knowledge.md` — the PC's working picture: facts learned, beliefs held
  (including mistaken ones), and questions still open. Update it whenever a
  scene reveals or overturns something. This is what narration may draw on.
- `gm/` — the truth the PC has not learned: hidden motives, unrevealed
  identities, off-screen events. Never player-facing. Write here when you
  establish something true that the PC has not perceived.

Before narrating, check the outcome against both. A fact in `gm/` must not
surface in the log or in chat until the PC observes it or is told.

## Retconning

You may change a fact after the fact, but only in the layer the PC has not
perceived. The test is perception: if every session-log entry and everything in
`state/knowledge.md` still reads exactly as before, the retcon is invisible and
allowed. What the PC saw, heard, or was told stays fixed; the cause behind it
may change.

Use it to repair a plot that cannot otherwise be made to work — a contradiction
with no way forward, a dead end you created. Do not use it liberally, and never
to dodge a consequence the fiction already earned. Prefer writing forward, or
revealing that a belief was wrong, before reaching for this.

Record each retcon in `gm/retcons.md`: what changed, and why.

## Truth, perception, and world files

`world/` describes what the PC has observed or could observe: places, people,
and factions as they appear. It is player-facing. A hidden motive, an unrevealed
identity, or an off-screen plan belongs in `gm/`, not here.

Create a file the first time a location, NPC, or faction appears, using the
frontmatter shape documented in each directory's `README.md`. Update the file
when the fiction changes something about it — and when the PC learns that an
earlier impression was wrong, record the correction in `state/knowledge.md`
rather than editing history. Link between files with relative markdown links
where it helps.

## Commands

```
journal roll <table> [--campaign <name>] [--game <id>] [--tag <tag>] [--count <n>]
journal oracle [<question>] [--complicate] [--campaign <name>] [--game <id>] [--table <name>]
journal dice <expr>
journal tables [--campaign <name>] [--game <id>]
journal check [--campaign <name>] [--game <id>]
journal new-campaign <name> [--game <id>]
journal games
journal game [<id>]
journal <game-command> [...]          provided by the campaign's game package
```

`journal games` lists the installed games; `journal game <id>` shows one game's
rules, tables, and commands.

Run `journal check` after adding or editing tables, and before ending a session
where you touched many files.

## Starting a new campaign

1. If the game does not exist yet, build it under `games/<id>/` following
   `docs/games.md` (copy `games/generic/` as a starting point).
2. `journal new-campaign <name> --game <id>`
3. Fill in `campaign.md` with the player.
4. Create the PC sheet in `characters/`, drawing on the game's backgrounds.
5. Open the first session log in `sessions/`.
