grida

Grida AI agent system work: `@grida/daemon` (DaemonServer, loopback HTTP perimeter, files/workspaces, secrets store, daemon discovery) and `@grida/agent` (the agent tenant: sessions, providers/BYOK, runtime/tool execution, skills discovery, prompts, tiers, sandbox hosts). Use for `packages/grida-daemon/**`, `packages/grida-ai-agent/**`, desktop sidecar protocol changes, agent chat transport, and bugs in agent state or streams. For pure Electron window, preload, menu, deep-link, or CDP work, use `desktop`.

Research, compare, and update AI model configurations. Covers text model tiers, image and video generation models, image tool models, release provenance, pricing data sourcing, and provider-cost metering against prepaid org credit. Use when bumping model versions, adding new models, updating pricing, or auditing model specs against provider documentation.

React-specific code shape in the Grida editor. Hooks cannot be tested or benchmarked and silently break tuned UX under layered composition, so they are barred from the engine and main system — load-bearing logic lives in classes and namespaces, hooks only as thin edge wires. `data-testid` follows component-root discipline: one per significant component, not scattered. Use when authoring React in `editor/grida-canvas-react/`, `editor/components/`, `editor/scaffolds/`, or `editor/app/*`.

TypeScript code shape inside a well-named module — taste, not lint. Prefer one class or namespace per file (the unit a test targets) over scattered free exports; consolidate related code, don't fragment. The unit of code should be the unit of spec. Use when authoring TS in `editor/grida-canvas*`, `editor/lib/`, or `packages/*`. Sibling to the `naming` skill; React-specific shape lives in `code-react`.

Use BEFORE editing any file in `supabase/migrations/` or `supabase/schemas/`, OR when the user runs a `/database` subcommand (`compact local migration`, `rls scenarios`, `align`). Encodes the three contracts that protect the Grida database layer: applied migrations are immutable, RLS implementation mirrors tests (never the reverse), `schemas/*.sql` is the human-readable end-state. Companion to `supabase/AGENTS.md` (RLS, grants, security boundaries).

Grida Desktop Electron shell and release-impact work: BrowserWindow, preload, `window.grida`, menus, protocol/deep links, file associations, Forge, path-scoped bridge security, Electron-only UI bugs, and CDP / Playwright verification. Use for `desktop/`, `editor/app/desktop/**`, `editor/scaffolds/desktop/**`, `editor/lib/desktop/**`, `/desktop/*` CSP, GRIDA-SEC-004, and deciding whether linked-package or hosted-renderer changes require a native Desktop version bump or coordinated release. For implementing daemon/agent-tenant core behavior, use `agent-system` as well.

Decide which family a doc belongs to before drafting — SDK/developer, user/product, or working-group (WG) — since family sets the audience, home, and tone. Use when creating, moving, or restructuring docs, when unsure which directory a doc belongs in, or when a request says "document this" / "write docs for X" without naming the kind. Routes to the specialized skill for each family.

Author and manage user-facing documentation for the Grida Canvas editor. Covers writing style, tone, product screenshots, demo state preparation, and content structure for pages under docs/editor/. Use when creating or editing canvas editor documentation, capturing screenshots of canvas features, or planning visual demos. Trigger phrases: "write user docs", "document this feature", "screenshot for docs", "canvas user guide", "update help page".

Author SVG figures for Grida docs — diff-able, version-controlled vector diagrams embedded in doc pages instead of screenshots. Provides reusable primitives (selection chrome, size badges, anchor pins, resize cursors, click ripples), color/typography tokens, a starter template, and finished examples to crib from. Canvas user docs (docs/editor/) are the first consumer; the kit is meant to generalize to any product's docs. Use when drawing diagrams that explain UI behaviour — gestures, alignment, before/after states — that a screenshot alone can't capture. Trigger phrases: "svg diagram", "draw a figure", "visual for docs", "explain this gesture visually", "before/after diagram".

Doctrine for drafting and keeping working-group docs under `docs/wg/**` — RFC/RFD specs and findings/research/glossary. A WG doc is a language-agnostic, code-agnostic study of a domain: it argues *why* and defines *what*, never *how in our code*. Use when writing or editing anything under `docs/wg/`, an RFC/RFD, a spec, a design note, a glossary, or research findings — including "write up the design", "document the spec", or "capture what we learned". Not for plans/TODOs (untracked `*.plan.md`), user docs, or SDK API refs — use `docs` to route those.

Author and edit a Grida `.canvas` board — a `.canvas.json` manifest plus document files (references, generated images, notes) placed on an infinite canvas. Use when working on a `.canvas` bundle or arranging visuals/design work spatially. For a linear deck/presentation, use the `slides` skill instead.

Guides performance investigation, benchmarking, and optimization of the Grida Canvas web editor (TypeScript reducer, Immer, React hooks). Use when profiling reducer dispatch cost, diagnosing slow interactions (drag, resize, color change), writing or running editor benchmarks, instrumenting with PerfObserver, or optimizing the JS-side state management pipeline.

Working pattern for enterprise-edition features in Grida — the commercial/hosted concerns (entitlement, BYOD, billing) on top of the OSS core. Anchor for the `GRIDA-EE: <surface>` grep marker, `(ee)` route group, `*-hosted` package suffix, and namespaced `grida_*` schema. Use when adding or touching an EE-only feature, or deciding whether a feature is EE territory. Surface skills (`ee-billing`) are siblings.

Surface workflow for billing in Grida — Stripe (subscriptions) + Metronome (AI credit ledger). The stable contracts: `grida_billing.*` is not REST-exposed (views/RPCs only), `fn_billing_apply_*` are the single mutation points, webhook receivers are `GRIDA-SEC-001`, BYOK is the `GRIDA-SEC-003` carve-out. Use when touching `editor/lib/billing/`, `editor/scripts/billing/`, the `grida_billing` schema, the webhook receivers, or the entitlement gate. Companion to `ee`.

Bug-fix discipline — every defect has an etiology, the chain of cause that produced the observable fault; trace it before patching. Errors only grow: a bandaid leaks unless genuinely localized and leak-free. Walk the diagnostic ladder (presentation → proximate cause → API contract → isolated or systemic) before writing the fix. Use when authoring or reviewing any bug fix, regression patch, "quick fix" PR, or when deciding whether to ship, defer, or refactor.

Guides authoring, organizing, and referencing test fixtures in this repo. Use when creating new fixtures, writing tests that depend on fixtures, or deciding what should be checked into git. Engine fixtures (rendering corpora) live in the engine repo.

Working pattern for Grida Gateway (GG) — Grida's first-party, metered, no-BYOK AI surface: the scoped-token mint, the OpenAI-compatible + native gateway endpoints, the `gg` client provider, and the desktop wiring that spends org credit without a user key. Anchor for the `GRIDA-GG: <surface>` grep marker; its security half is `GRIDA-SEC-006`. Use when adding or touching any GG file, the `gg` provider kind, the `gg:ai` token audience, or deciding whether code belongs to the gateway surface. Companions: `security` (the GRIDA-SEC-006 half), `ee-billing` (the ledger it spends), `agent-system` and `desktop` (the two hosts).

Establish what is actually true and current for the surface you are about to change — not just search. Grounding = locate the authoritative source and reconcile sources that disagree (code vs doc, migration vs schema, memory vs current code, live vs archived), not take the first hit. Use before any grep/find/explore of the codebase or docs, when deciding which of several definitions is the real one, or when a doc or memory conflicts with the code. Covers the source-of-truth hierarchy, reconciliation discipline, scoped ripgrep, and the docs/tags.yml + docsearch.py index.

Guides work on the Figma I/O package (@grida/io-figma, packages/grida-canvas-io-figma/). Covers the fig-kiwi binary parser, Kiwi→REST→Grida conversion pipeline, fig2grida CLI, REST API JSON conversion, and testing with clipboard/fig/REST fixtures. Use when adding node type support, fixing conversion bugs, extending fig2grida, working on the fig-kiwi parser, writing tests for Figma import, or debugging clipboard paste failures after a Figma update.

Guides work on the Grida file format (.grida) from the TS side: the I/O packages that read/write it (loading, archive packing, clipboard) and the frozen schema bindings. Use when working with .grida files in the editor or packages, or debugging format round-trip issues. (The schema and the Rust decoder live in the engine repo.)

Write any link or URL so it resolves where it is rendered, not where it lives in the repo. Use when authoring or editing a link — in docs, source docstrings, READMEs (incl. npm-published), or product UI: docs cross-refs, "see SECURITY.md", universal `/_/` routes, GitHub URLs.

How to think about names in the Grida repo — not conventions, but what a name commits you to, reveals about the system, and costs to change. The central discipline is that a strict, honest name refuses to grow, and that refusal drives the repo's shape (flat modules, small agnostic packages, suffix siblings). Use when planning a new package, crate, module, directory, route group, or test corpus — the name comes first.

Set up, download, verify, and seed the optional Grida Library developer corpus into local Supabase. Use when Library browse/search, Desktop reference picking, or agent Library tools need realistic local assets and Gemini embeddings; also use when changing the gridaco/grida consumer for gridaco/library developer-corpus releases.

Pre-PR discipline for a public-by-default repo. What a reviewer enforces beyond CI: secrets and internal data in diffs or screenshots, docs that name their reader, and the cleaning pass where incomplete or confusing artifacts get dropped. Use before opening any PR against `gridaco/grida` or when finalizing work for review.

Role profile — a reviewer who is fact-seeking, bedrock-seeking, honest, and rejecting. Demands that arguments rest on small facts that cannot be wrong (not on stacked assumptions dressed up as foundation), and that deliberately-unclear concepts be quarantined — never leaked into solid layers, never mixed with each other. Catches the failure mode where designs ship after partial grounding: most of the spec researched, the design feels finished, and the unresearched remainder holds the deal-breaker. Invoke with `/pedantic <target>` (e.g. `/pedantic review this design doc`, `/pedantic review the SDK design`, `/pedantic review this PR`). Probes cover logical structure (definitions, assumptions, boundaries, contradictions, unfalsifiability, vague quantifiers, counterexamples), epistemic honesty (researchable vs. discoverable-only-by-doing), bedrock integrity (assumed-bedrock, leaked uncertainty, mixed unclarity), and design pathology (YAGNI, wrong-layer abstraction, unclear responsibility, fragmentation, over-engineering). Use when you want a hard critique of a plan, design doc, technical doc, code change, or PR description — not a copy edit, not a vibe check.
