## House rules
These apply in every Craft repository. A later rule may be stricter, not weaker. The source is `standards/house-rules-core.md` in `storytold/craft-contrib`. Propose changes there, not in a copy.
1. **A person is accountable.** Whoever runs an agent answers for what it opens and for its review comments.
2. **Check, then claim.** Before writing code, read the issue comments, search pull requests for `#N` and the keywords, and check recent commits on `main`. Comment on the issue first. Release a claim you will not finish.
3. **Verify, don't guess.** Open a definition before using it. Confirm the cause in the code, even when someone names a location.
4. **Keep fixes narrow and tested.** Fix what the issue describes, where the bug is. Add a test that fails without the fix.
5. **Review the diff before opening a pull request.** Identifiers exist as used, the test fails without the fix, nothing unrelated changed, and the description is true.
6. **Look for a better pull request.** If another fixes the same thing, close yours when it is better or equal, and say why.
7. **Report only what ran.** Say what you tested and what you could not run. Without a local build or test, say so and rely on CI before marking ready.
8. **`main` changes through a pull request.** Do not push to it. Branch protection enforces this. There is no exception.
9. **Stop and ask only about** licensing outside the allowlist, publishing, releases, a new remote, secrets, spending money, destructive git, and anything else hard to undo. Otherwise keep working. `plan/` is a gitignored notebook, not rules. Without it, do not ask for it and do not stop.
10. **Keep secrets and personal details out** of the repository, logs and requests.
11. **CI stays shared.** Workflows call `storytold/craft-common-actions`. Do not change CI in a feature or fix pull request. If CI cannot cover a change, open an issue there.
12. **Guards say why.** A check that looks removable says what it prevents. Read that before changing it.
13. **Instructions must be readable by everyone.** No notes about one machine, and no links to files a reader cannot open. `craftrules` is retired. Do not link to it.
14. **Keep pull requests moving.** Concurrent pull requests are fine; unanswered actionable feedback is not. Respond in 7 days, a reminder at 14, closure eligible at 30, from when an actionable request waits on the author. Suggestions and unconfirmed bot findings do not start the clock. A fix, explanation or agreed plan resets it; unrelated activity does not. Waiting on a reviewer or maintainer pauses it and does not count against the author. A maintainer decides closure; it is never automatic. Reuse search results, do not poll, and stop at a rate limit.
15. **No agent attribution.** A pull request does not say an agent wrote it. A repository rule may not require that.

## Rust Craft repositories
These apply to native Craft apps and to shared Rust libraries. Select them by repository type. A repository that merely contains some Rust does not take this block. Rules later in a repository's file may be stricter, but not weaker. The source is `standards/house-rules-rust.md` in [storytold/craft-contrib](https://github.com/storytold/craft-contrib).
1. **Never crash.** Non-test code does not panic and has no `unsafe`, except where the repository file names an exception. Return errors, treat input as hostile, and bound recursion and allocations. New production crate roots copy the `deny` attribute from an existing crate: `clippy::unwrap_used`, `clippy::expect_used`, `clippy::panic`, `clippy::unimplemented`, `clippy::todo`, `clippy::unreachable`. Every crash fix comes with a test that panicked before the fix.
2. **Clean room.** Learn from observed behaviour and public specifications. Do not copy another product's code, assets, strings or artwork. Check a dependency's licence before adding it.
3. **Assets and fonts.** Every asset is original or suitably licensed, and is recorded in `ATTRIBUTION.md` in the same change. Font files live in [storytold/craft-fonts](https://github.com/storytold/craft-fonts), not in the app repository.
4. **Rust only for native Craft apps.** No handwritten JavaScript or TypeScript, and no Tauri, Electron or webview shell, in those apps. Shared tooling follows its documented technical scope and maintainer-approved exceptions. Craft PR Review's existing Tauri and TypeScript UI is one such exception. It does not relax this rule for native apps. Preserve any existing web build.
5. **Time goes through `chrono`.** Do not hand-roll calendar conversion. For dates beyond what `chrono` can represent, follow [standards/time.md](https://github.com/storytold/craft-contrib/blob/main/standards/time.md).
6. **Contributor credits.** Add or edit only your own person's entry in `contributors/people.toml`, and only after asking them. Never guess a name or hand-edit `contributors.json`.
## Licence allowlist
Dependencies and assets use SPDX identifiers. An expression is allowed when every identifier is in this list. A repository may name a shorter list. It may not add an identifier here by editing its own copy of these rules.
- `ISC`
- `MIT`
- `BSD-2-Clause`
- `BSD-3-Clause`
- `Apache-2.0`
- `OFL-1.1`
- `Ubuntu-font-1.0`
- `Bitstream-Vera`
- `CC0-1.0`
- `CC-BY-4.0`
- `CC-BY-SA-4.0`
- `LicenseRef-Public-Domain`
`LicenseRef-Storyteller-Trademark` is not in this list. It covers Storyteller brand marks only, where a repository already says so.

## 3. Engineering rules
See `CLAUDE.md`: pure Rust, dependency layering (`cargo xtask layers`), exact `Tick` time, everything is
a command, everything is agent-drivable, and the quality gates (`cargo xtask ci`) before every commit.
- **Layering** (`cargo xtask layers`): nothing below L5 depends on egui/eframe/winit/rfd/cpal; L0–L4 build for wasm32.
- **Exact time:** `effectcraft_time::Tick` (254 016 000 000/s). Keyframe times are layer time.
- **Property tree:** everything animatable is a `Property` in the layer's `PropGroup` tree, addressed by paths (`transform/position`, `effects/#1/blurriness`, `@uid`).
- **Everything is a command** (`crates/engine`): id, label, menu path, shortcut, params, enabled(), run(). UI, CLI, control channel and MCP dispatch by id.
- **Everything is agent-drivable:** every interactive widget registers an automation id; UI state is serde.
- **Community links** (Help menu, About, header Discord button): https://discord.gg/artcraft, https://getartcraft.com, https://getartcraft.com/apps/effectcraft, https://github.com/storytold/effectcraft.
- **Quality gates** before every commit: `cargo xtask ci` (fmt, clippy -D warnings, tests, layers, assets, wasm).
- New workspace crates include `[lints] workspace = true` in `Cargo.toml`. Production crate roots declare the crate-level lint attributes before modules; crate-level `//!` documentation may precede them.
- **Commits:** one task id per commit (`M6.3: trim paths`). Only green states.
- `cargo run -p effectcraft -- --control 9877` opens the desktop app with the JSON-lines control server (`docs/control-protocol.md`). For UI work, look at the result, including the headless `snapshot` example.
- `plan/` is an optional gitignored notebook (`plan/aftereffects/` may hold reference notes and captures). Do not ask for it, do not stop when it is absent, and never commit those captures.
- Read [`docs/gaps.md`](docs/gaps.md) and [`docs/target-app-parity.md`](docs/target-app-parity.md) before choosing work. Fidelity, reliability and stability (G1–G3) come before new features.
- Some workflow files still run their own jobs. Don't add to them. Moving a job into craft-common-actions is its own task.
- **Time goes through `chrono`** (workspace dependency). Never hand-roll UTC/calendar conversion (days-to-date algorithms, leap-year math); a crate owns only its output format string. The one exception is range extension: past the years chrono can represent, shift the date by whole 400-year Gregorian cycles (146,097 days, after which the calendar repeats), let chrono compute the month and day, and add the cycles back to the year (splitting seconds into hours, minutes and seconds is plain arithmetic).

# EffectCraft — instructions for agents
EffectCraft is a clean-room, open-source, pure-Rust motion graphics and visual effects compositor targeting Adobe After Effects parity (and beyond). Native on macOS, Windows, Linux; web via WASM. Sibling of `../photocraft` (Photoshop), `../pdfcraft` (Acrobat), `../vectorcraft` (Illustrator), `../filmcraft` (Premiere), `../lightcraft` (Lightroom) and `../designcraft` (InDesign), with the same conventions.
## Start every session here
`plan/` is maintainer-local (gitignored). Public equivalents: [`ROADMAP.md`](ROADMAP.md), [`docs/`](docs/).
1. Read `plan/STATUS.md` (current milestone, next task, running agents, blockers).
2. Read the task in `plan/execution-plan.md` §3, the relevant section of `plan/architecture.md`, and the crate README/docs you touch. Feature ids: `plan/aftereffects/feature-catalog.md`; effects: `plan/aftereffects/effects-list.md`; UI reference: `plan/aftereffects/README.md`.
3. Read [`docs/gaps.md`](docs/gaps.md): every known shortfall, ranked, and the prioritised workstreams; the numbers are in [`docs/target-app-parity.md`](docs/target-app-parity.md). Fidelity, reliability and stability (G1–G3) come before new features.
4. Follow the autonomous operation protocol (`plan/execution-plan.md` §7). Don't stop to ask.
## Non-negotiables
**Read [`AGENTS.md`](AGENTS.md) first; its rules override everything here.** No Adobe assets, every asset licensed + attributed (`cargo xtask assets`).
- **Never crash** (AGENTS.md "Never crash"; outranks feature work: a crash loses people's work). Non-test code has no `unwrap()`/`expect()`/`panic!`/`unreachable!`/`todo!`/`unimplemented!` and no `unsafe`: return `Result` and use `?`, `ok_or`, `let … else`. Input-derived indices, slices and arithmetic use `get()` and checked/saturating math; recursion is depth-limited; locks handle poisoning. The app's last-resort guard turns an escaped panic into an error and keeps the document. Every crash fix gets a regression test.
- **Clean-room.** Behaviour and public docs only. No GPL/LGPL/AGPL code. ffmpeg only as an external test oracle.
- **Pure Rust.** Media codecs come from FilmCraft crates (git deps behind `crates/media`, see `plan/adr/0001`).
- **Layering** (`cargo xtask layers`): nothing below L5 depends on egui/eframe/winit/rfd/cpal; L0–L4 build for wasm32.
- **Exact time:** `effectcraft_time::Tick` (254 016 000 000/s). Keyframe times are **layer time**.
- **Time goes through `chrono`** (workspace dependency). Never hand-roll UTC/calendar conversion (days-to-date algorithms, leap-year math); a crate owns only its output format string. The one exception is range extension: past the years chrono can represent, shift the date by whole 400-year Gregorian cycles (146,097 days, after which the calendar repeats), let chrono compute the month and day, and add the cycles back to the year (splitting seconds into hours, minutes and seconds is plain arithmetic).
- **Property tree:** everything animatable is a `Property` in the layer's `PropGroup` tree, addressed by paths (`transform/position`, `effects/#1/blurriness`, `@uid`).
- **Everything is a command** (`crates/engine`): id, label, menu path, shortcut, params, enabled(), run(). UI, CLI, control channel and MCP dispatch by id.
- **Everything is agent-drivable:** every interactive widget registers an automation id; UI state is serde.
- **Community links** (Help menu, About, header Discord button): https://discord.gg/artcraft, https://getartcraft.com, https://getartcraft.com/apps/effectcraft, https://github.com/storytold/effectcraft.
- **Quality gates** before every commit: `cargo xtask ci` (fmt, clippy -D warnings, tests, layers, assets, wasm).
- **New workspace crates** must include `[lints] workspace = true` in `Cargo.toml` to inherit `[workspace.lints]`. Production crate roots must declare the required crate-level lint attributes before modules or other crate items; crate-level `//!` documentation may precede them.
- **Commits:** one task id per commit (`M6.3: trim paths`). Only green states.
## Running and looking at the app
- `cargo run -p effectcraft -- --control 9877` opens the desktop app with the JSON-lines control server (`docs/control-protocol.md`).
- For UI work, **look at the result**. Headless (no window, works while the user is busy on the machine): `cargo run -p effectcraft-ui-egui --example snapshot -- --out ui.png --step '{"method":"engine.execute","params":{"command":"layer.select","params":{"layers":["#2"]}}}'` (steps are control-channel requests; `--script steps.jsonl`; `{"method":"snap","params":{"path":…}}` for intermediate shots). Or drive the live app via the control channel and take `ui.screenshot` (needs the window visible on screen).
- After Effects reference: drive AE via ExtendScript (`osascript -e 'tell application "Adobe After Effects 2026" to DoScriptFile "x.jsx"'`) and capture only AE's window (`screencapture -l <windowid>`); keep captures in `plan/aftereffects/ref/` (gitignored), never commit them, never capture the Home screen.
- Parallel agents: separate git worktrees and `CARGO_TARGET_DIR=target/agent-<name>`; keep every `Cargo.toml` valid (the `crates/*` glob).
## CI workflows
- Workflows in `.github/workflows/` call the shared workflows in [`storytold/craft-common-actions`](https://github.com/storytold/craft-common-actions) at `@main`, with their inputs and secrets. No other jobs: if no shared workflow does what's needed, it doesn't go here.
- Don't add or change CI in a feature or fix PR. If the existing workflows can't build or test a change, link an existing craft-common-actions issue or PR, or open a new issue, or a PR only for a small fix that is safe for every app and does not increase CI time.
- Some workflow files here still run their own jobs. Don't add to them. Moving a job into craft-common-actions is its own task, never part of another PR, and the job stays here until a shared workflow runs it.
