sim

Create or update a Sim integration block with correct subBlocks, conditions, dependsOn, modes, canonicalParamId usage, outputs, and tool wiring. Use when working on `apps/sim/blocks/blocks/{service}.ts` or aligning a block with its tools.

Gate a block's visibility — ship an unreleased block as a preview (hidden until revealed via AppConfig/env), reveal it to admins/orgs, GA it, or kill-switch a shipped block

Add a new table column type to Sim — registry entry, icon, storage shape, coercion, and the behavioral hooks the grid and API read. Use when adding a value kind under `apps/sim/lib/table/column-types/`.

Add or update a Sim knowledge base connector for syncing documents from an external source, including auth mode, config fields, pagination, document mapping, tags, and registry wiring. Use when working in `apps/sim/connectors/{service}/` or adding a new external document source.

Add a code-defined table enrichment (registry entry) under `apps/sim/enrichments/` backed by an ordered provider cascade, ensuring every provider tool it calls has hosted-key support. Use when adding a per-row table enrichment that fills cells via existing Sim tools.

Add a runtime feature flag (AppConfig-backed on prod, secret fallback off-prod), global by default or optionally gated by workspace id, org id, user id, or platform admin

Add hosted API key support to a tool so Sim provides the key (metered and billed to the workspace) when a user has not brought their own. Use when adding a `hosting` config to a tool under `apps/sim/tools/{service}/`.

Add a complete Sim integration from API docs, covering tools, block, icon, optional triggers, registrations, resolved-secret/model-input safety, and integration conventions. Use when introducing a new service under `apps/sim/tools`, `apps/sim/blocks`, and `apps/sim/triggers`.

Add or upgrade a curated, immutable managed CLI for Sim Function sandboxes, including client-safe catalog metadata, a pinned server-only installation recipe, checksum and executable verification, provider compatibility, PATH propagation, content-addressed image identity, and tests. Use when adding a CLI to the Sandbox managed-CLI selector or changing an existing managed CLI version or recipe.

Add a new LLM model to apps/sim/providers/models.ts with specs verified against the provider's live API docs (no hallucination)

Add a new governed item to Sim's enterprise permission groups — a boolean restriction, an allowlist, or a denylist — wired end-to-end from the field registry through the capability rule to the server gate that actually refuses. Use when adding a key to `PERMISSION_GROUP_FIELDS` or a capability to `CAPABILITY_RULES`.

Add or update a Sim dynamic selector using the shared manifest, server attachment, and selectors.execute path. Use for provider-backed, internal, or local option lists referenced by block, trigger, or connector selectorKey fields.

Add a new Sim settings page, or audit existing settings pages for design-system compliance with the shared SettingsPanel layout. Use when creating a settings tab, or when asked to check/clean up settings pages so they match the design system (consistent title, header, search, spacing).

Create tool configurations for a Sim integration by reading API docs

Create webhook or polling triggers for a Sim integration

Drive a PR to a clean review (Greptile 5/5, zero open threads) — ships if needed, keeps it mergeable against staging, re-triggers both Greptile and cubic, fixes real findings, replies to and resolves every thread, and loops until clean

Run all code quality skills — effects, memo, callbacks, state, React Query, emcn design review, url-state, comments, and test-audit — analyzing in parallel, then applying fixes sequentially

Spawn parallel task agents to explore a given area of the codebase from multiple angles, then use their findings to answer the question or build a plan. Use when a task needs broad fan-out exploration across many files before acting.

Author or review a Drizzle DB migration for zero-downtime safety — expand/contract phasing, backward-compatibility with the deployed app version, and writing the `-- migration-safe` acknowledgment the check:migrations lint requires. Use when adding/editing files under `packages/db/migrations/` or changing `packages/db/schema.ts`.

Anti-slop frontend skill for landing pages, portfolios, and redesigns. The agent reads the brief, infers the right design direction, and ships interfaces that do not look templated. Real design systems when applicable, audit-first on redesigns, strict pre-flight check.
