# 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. Standard: [craftrules `standards/never-crash.md`](https://github.com/storytold/craftrules/blob/main/standards/never-crash.md).
|
||
- **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**.
|
||
- **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).
|
||
- **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).
