Paged ListsAAny list that can grow without bound is paged, never drawn whole. Lists of rows page at LIST_PAGE (20) through createPager from src/components/styled/pager.tsx; grids of squares page at their grid size (BOX_SIZE for the pokemon box, GRID_SIZE for the item tray). Applies whenever rendering a collection whose length the player controls.developmentgoawsVotes: 0GitHub stars: 5
Dialog LayoutADialog furniture is drawn and aligned by the styled primitives: the title sits on a blue nameplate across the sheet's top edge, and the DialogActions dock at the foot puts the way out on the left and the actions on the right. A dialog has one way out, a button of its own. Applies when building or changing any dialog in src/components.developmentgoawsVotes: 0GitHub stars: 5
Device SettingsAHow a setting that belongs to the machine rather than to the account is stored and read: one module signal in src/components/app/settings.ts, one JSON key in localStorage, loaded after hydration. Applies whenever adding a preference a player sets for themselves, or reading one from a component or from canvas code.developmentrustgoVotes: 0GitHub stars: 5
Turn DurationsAA mainline turn is worth two seconds in this engine. Any duration taken from the main games — a status that lasts four turns, a residual that bites once a turn, a screen that holds for five — is written as turns(n) from src/battle/turn.ts rather than as a millisecond literal.developmentgoawsVotes: 0GitHub stars: 5
Resource SuspenseAA component that calls `createResource` must not read it. The declaration lives in one component body and every read of the data signal lives in a child, wrapped in `Suspense`. A signal filled in by an effect that only loads something is a resource written out longhand. Applies whenever adding a resource to a component, writing a new component that reads one, or writing an effect that loads.developmentgoawsVotes: 0GitHub stars: 5
Registry DescriptionsAHow to write the one-line `description` a registered item, ability or move carries. Applies whenever adding an entry to a data registry under src/data, or rewording an existing line. The line describes this engine's behaviour, not the mainline's, and is derived from the data wherever the data already knows the answer.developmentgoVotes: 0GitHub stars: 5
Prefer SetsAPrefer Set (and Map) lookups over Array + .some/.indexOf/.includes for membership checks. Applies whenever writing or reviewing code that tests "is X one of these values". O(1) hash lookup instead of O(n) scan, and intent reads clearer.developmentgoVotes: 0GitHub stars: 5
Prefer For OfAWrite for-of loops rather than callback-taking Array methods (map, filter, forEach, reduce, some, every, find, flatMap and the like). Applies whenever writing or editing any code in src.developmentgoreactVotes: 0GitHub stars: 5
Paged ListsAAny list that can grow without bound is paged, never drawn whole. Lists of rows page at LIST_PAGE (20) through createPager from src/components/styled/pager.tsx; grids of squares page at their grid size (BOX_SIZE for the pokemon box, GRID_SIZE for the item tray). Applies whenever rendering a collection whose length the player controls.developmentawsVotes: 0GitHub stars: 5
Light CommentsAKeep comments light: short enough to read at a glance, and about the why rather than the what. Applies whenever writing or reviewing a comment or a doc block. Most blocks are one to four lines; history, anecdote and restatement of the code below are cut.developmentrustgoVotes: 0GitHub stars: 5
Effect PropsAAn effect wakes on its sources changing, not on its answer changing. A component whose effects do stateful work — loading a sheet, starting a playhead, opening a subscription — reads those props through memos, so a caller that rebuilds its list does not restart everything in it. Applies whenever writing or reviewing a component with a `createEffect` fed by props.developmentgoVotes: 0GitHub stars: 5
Dialog TransitionsAThe `Transition` around a dialog decides when it is mounted and nothing else — the fade belongs to the `TransitionChild` overlay and panel inside it. Applies whenever adding or changing a transition in `src/components/styled`, or giving a dialog an animation of its own.developmentgoVotes: 0GitHub stars: 5
Deferred Jsx PropsAA prop whose markup is built outside a render — pushed onto a queue, held in a signal, sent from a promise — is typed `() => JSX.Element`, never `JSX.Element`. Applies whenever adding a prop or an API that stores markup and draws it later.developmentgoawsVotes: 0GitHub stars: 5
Component LayoutAHow a component is laid out on disk: when a single file becomes a folder, what the parts are called, and which way the imports run. Applies whenever adding to a component that is already long, or splitting one that has grown past reading in one sitting.developmentgoVotes: 0GitHub stars: 5
Batched QueriesAWhere `batchedQuery` from src/utils/batched-query.ts belongs, which is the browser, and why the server reads many keys with one query instead. Applies whenever writing or reviewing a read that fetches one key at a time, or reaching for batchedQuery.developmentVotes: 0GitHub stars: 5
Local AiAUse the local AI models LM Studio serves on the owner's desktop — rank GitHub issues by meaning before filing one (Tools/SemanticSearch), and ask Gemma 4 what changed between two screenshots or about a cropped detail (vision.ps1). Load before filing an issue or before comparing a batch of captures by eye, and only when LM Studio answers on localhost:1234.developmentpythonrustVotes: 0GitHub stars: 2
WorkflowAUse to walk the user through a guided policy review of the project's crosslink configuration — tracking mode, security policies, language rules, hook implementations, and workflow conventions. Identifies drift from defaults via `crosslink workflow diff` and offers targeted fixes or a `crosslink init --force` reset. Trigger when the user says "review the crosslink config", "audit the workflow policies", "/workflow", or asks whether the hook/rules setup is right.developmentbashtestingVotes: 0GitHub stars: 1,422
Review Pre CommitAUse as a pre-commit quality gate — review the working diff for stub patterns (TODO/FIXME/`unimplemented!()`/`todo!()`), debug leftovers (`dbg!`, stray `console.log`/`println!`, commented-out code), then run the project's lint, format, and test suites and verify the active crosslink issue is documented. Prints a PASS/FAIL checklist and hands off to `commit`. Trigger when the user says "review my changes", "/review", "ready to commit?", or asks for a final pass before committing.developmenttypescriptpythonVotes: 0GitHub stars: 1,422
PreflightAUse BEFORE implementing code in a crosslink-tracked project — loads `.crosslink/rules/global.md`, the language rules for detected manifests, the project rules, and the active `tracking-<mode>.md`. Replaces the heavy context that would otherwise be re-injected on every prompt. Trigger when the user says "preflight", "load the rules", "ground yourself", or before starting a fresh implementation session.developmentjavascripttypescriptVotes: 0GitHub stars: 1,422
MaintainAUse to run a periodic codebase-health pass — dependency audit, lint, test suite, dead code / TODO scan, doc freshness, crosslink issue hygiene, and build artifacts. Conservative by default (small fixes inline, larger work files a `maintenance`-labelled issue). Trigger when the user says "maintenance", "health check", "audit dependencies", "/maintain", or asks for a periodic project tidy-up.developmentjavascripttypescriptVotes: 0GitHub stars: 1,422
FeatureAUse to create a `feat/<slug>` branch from a human-readable description and register a matching crosslink issue (priority medium, label `feature`). Slugifies the description, validates preconditions (no uncommitted changes, branch doesn't already exist), and checks out the new branch. Trigger when the user says "new feature branch for X", "make a feature branch", or "/feature …".developmentbashVotes: 0GitHub stars: 1,422
FeatreeAUse to create a `feat/<slug>` bookmark AND spin up a new git worktree under `<repo-root>/.worktrees/<slug>`, then initialize crosslink hooks and an agent identity in the worktree so a child agent can work there. Trigger when the user says "make a worktree for <feature>", "/featree …", or asks to spin up an isolated workspace for a feature.developmentrustbashVotes: 0GitHub stars: 1,422
CommitAUse to create a jj commit AND auto-document the result on the active crosslink issue. Writes a conventional-style message with the issue ref, and adds a `--kind result` comment so the audit trail closes. Trigger whenever the user asks to "commit", "commit changes", "commit and push", or finishes a unit of work in a crosslink-tracked repo.developmentbashgitVotes: 0GitHub stars: 1,422
CheckAUse to check on background feature agents launched via /kickoff — running in tmux sessions or docker/podman containers. Reports each agent's state (Working / Idle / Waiting / Done / Error), captures recent output, and offers next-step commands. Trigger when the user says "check on the agent(s)", "how's the kickoff going", or names a `feat-*` / `crosslink-task-*` session.developmentgoshellVotes: 0GitHub stars: 1,422
