npm ci
npm run format
npm run check
npm run build
Run npm run format after edits and before npm run check so Prettier-only issues are fixed upfront. npm run check runs TypeScript type checking, unit tests, lint checks, Prettier check, CSS build verification, and a production esbuild bundle.
The local npm run check path runs checks in parallel and uses local caches where available. Use npm run check:ci when you need to reproduce the sequential, non-cached CI validation path.
main.js, styles.css, data.json, and node_modules/ are ignored by Git. main.js and styles.css are still the files Obsidian loads, so run npm run build after source changes.
CSS is authored in src/styles/ and generated into the ignored root styles.css release asset. Use npm run build:styles when only regenerating CSS, or npm run build:styles:check to verify that the authored CSS can be rendered.
Source Layout
The source tree is organized by responsibility rather than by the original single Obsidian plugin entrypoint:
src/main.tsregisters Obsidian views, commands, settings, and lifecycle hooks.src/app-server/owns the app-server boundary: transport, connection lifecycle, compatibility helpers, runtime payload helpers, RPC facades, protocol adapters, and shared app-server-backed cache state. Generated app-server payloads should stay behind this boundary; exported app-server services should expose panel-owned domain models or small local projection types unless an explicit boundary exception is documented.src/features/chat/owns the main Codex chat surface: ObsidianItemViewclasses, panel orchestration, request/app-server controllers, composer behavior, display models, chat-only UI renderers, runtime state and status projection, approvals, user input, thread actions, and panel-specific state.src/features/threads-view/owns the dedicated Obsidian thread list view, including app-server thread list rendering and live open-panel snapshot aggregation.src/features/selection-rewrite/owns the Markdown editor selection rewrite command, popover, prompt/output handling, and ephemeral rewrite thread runner.src/workspace/owns Obsidian workspace coordination across Codex surfaces, including panel discovery/opening, open-panel snapshots, and thread surface broadcasts.src/shared/contains feature-neutral helpers, including reusable DOM pieces and unified diff display helpers shared by chat and selection rewrite.src/settings/contains Obsidian settings models, settings-tab rendering, and app-server-backed dynamic settings data.src/domain/contains panel-owned, generated-independent meaning models and pure derivations shared by app-server, features, workspace, and settings code. This includes catalog metadata, runtime policy/settings/metrics, server metadata/diagnostics, chat input, and thread title/history/reference/transcript/archive helpers. Domain code must not import app-server protocol, generated bindings, feature modules, UI, or Obsidian APIs; app-server protocol and service modules adapt generated payloads into domain models at the boundary.src/styles/contains the authored CSS modules andorder.jsonconcatenation order.scripts/build-styles.mjsconcatenates them into the ignored rootstyles.css, which remains the Obsidian release asset.
Keep new code near the state or API it owns. Feature-to-feature imports are allowed when the imported feature owns a concrete capability or integration point, such as thread export, thread title generation, or an Obsidian view. Do not use another feature as a generic utility bucket; move truly feature-neutral behavior to src/shared/, src/domain/, or src/app-server/. Lower-level modules in src/app-server/, src/domain/, and src/shared/ must remain independent from src/features/; ESLint enforces that dependency direction. Within the lower-level modules, src/domain/ and src/shared/ remain below the app-server boundary: app-server code may depend on domain models to adapt protocol data, but domain and shared code must not depend on app-server modules or generated app-server bindings.
Codex Panel's runtime UI is Preact-owned through direct Preact APIs. Keep chat panel UI, the Threads view, and the selection rewrite popover in Preact components; use imperative DOM writes only for explicit bridge modules or Obsidian-owned API boundaries such as MarkdownRenderer, virtualizer measurement glue, diff rendering, icon rendering, SuggestModal, and the Obsidian Setting-based settings tab.
Chat panel state belongs in ChatStateStore. Panel-visible state changes should dispatch named reducer actions and flow through the shell-state adapter; do not add controller-owned signals, ad hoc Preact state mirrors, generic state patch actions, or a non-Preact UI runtime without revisiting the project design notes.
App-Server Bindings
The app-server TypeScript bindings in src/generated/app-server/ are generated from the installed Codex CLI:
npm run generate:app-server-types
npm run check
The generation script uses codex app-server generate-ts --experimental because the panel depends on experimental app-server fields such as collaboration mode and generated v2 types.
API Baselines
Use the local API baseline report when checking whether the development environment matches the supported API policy:
npm run api:baseline
npm run api:baseline:check
Obsidian API compatibility follows semver within the guaranteed minor. manifest.json and versions.json define the minimum supported Obsidian app minor with a .0 patch version, while the obsidian npm dev dependency tracks the latest patch in that same minor using a ~ range. When the Obsidian API minor is raised, update manifest.json, versions.json, README requirements, and the obsidian dev dependency together.
Codex app-server compatibility is managed by Codex CLI minor version. README records the tested Codex CLI patch version, and the baseline check verifies that the local codex --version is in the same minor before app-server binding or compatibility work.
