Use when rendering or sourcing a custom app's icon/favicon or screenshot/art on ANY surface — the homepage launcher card (web-app/src/pages/launcher), the admin apps browser (web-app/src/pages/admin/AdminCustomApps), an app rail tile, or any new place that shows an app's picture. Also when adding icon/art fields to an…

Use when adding or modifying a custom-app serving route (crates/app/src/server/api/customappsserve.rs, the /customer-apps/{path} handler in serve.rs) or a custom-app data endpoint (projects/query.rs, projects/semanticquery.rs). Encodes the serve-plane + data-plane performance guardrails so every custom app stays fast.…

Use when adding, moving, or renaming an HTTP route under crates/app/src/server/router/ (any .route(...) / .nest(...) mount), or writing a request handler that reads the workspace working copy, .git, or the local state dir (configmanager.workspacepath(), ConfigManager::resolve, resolvestatedir()…

Use when adding or modifying code in crates/app/src/server/ or HTTP handlers that involves long-running compute, periodic schedules, multi-step pipelines, or any work that must survive instance death. Triggers include "spawn a background task", "schedule periodically", "run async after returning", "long-running…

Use when writing, reviewing, or debugging an Oxy Airway ELT pipeline (.airway.yml) — sources, the kind values Oxy actually wires, credentials, reset, rewind and retry — or when one misbehaves: "unsupported source kind", a pipeline that parses then fails at run time, credentials that do not resolve, a pipeline run…
Skill Claude CodeCodex
Use when writing, debugging, or reviewing an Oxy automation (a .automation.yml / legacy .procedure.yml workflow — tasks, loops, variables, schedules) in a customer workspace, or when an automation run misbehaves: an httprequest task that works locally and fails in cloud, a file that is silently not an automation, a…
Skill Claude CodeCodex
Use when you need data out of an Oxy deployment — querying a customer's warehouse or semantic layer, reading threads/runs/apps/orgs, checking why an endpoint 4xxs, or reproducing a customer-reported bug against real data. Also when you need to know which endpoints exist or what body one takes. Triggers on "query the…
Skill Claude CodeCodex
Use when building, debugging, reviewing, shipping, or verifying an Oxy custom-app bundle (a code-first React/Vite app served by Oxy at /customer-apps/ / /), including writing Oxy Functions, driving them from the UI, and checking a published app in the browser with the Playwright MCP server (no CI checks a published…
Skill Claude CodeCodex
Use when deciding where an aggregate gets materialised — writing an executesql rollup, chaining one after an airway ingest step, choosing rollup vs semantic preaggregations, or whether raw rows must be retained — and on the symptoms: a dashboard that aggregates at query time, a load that wrote every row yet failed…
Skill Claude CodeCodex
Use when writing, reviewing, or debugging an Oxy semantic model — .view.yml views, .topic.yml topics, measures, dimensions, entities, pre-aggregations (rollups), and the meta: freshness block — in a customer workspace, and when one misbehaves: a measure that vanishes after switching topics, "measure not found", a…

React composition patterns that scale. Use when refactoring components with boolean prop proliferation, building flexible component libraries, or designing reusable APIs.

Use when creating, editing, reviewing or debugging an Oxy agent, a .agentic.yml file that answers questions from the semantic model by clarifying, specifying, solving (SQL), executing and interpreting. Triggers include "create an analytics agent", "my agent picks the wrong metric", "my solving instructions are…
Skill Claude CodeCodex
Use when creating, editing, reviewing, or debugging an Oxy Data App — a declarative .app.yml file of tasks (executesql, semanticquery) and displays (tables, line / bar / pie charts, markdown, side-by-side rows) — for a dashboard, report, KPI page, or data app, including interactive filters: dropdowns, date pickers…
Skill Claude CodeCodex
Use when writing, running, or acting on evals for an Oxy agent — .test.yml files that run an .agentic.yml agent and score its answers with an LLM judge — and when the agent's answers are wrong. Triggers: "add a test", "write a test case", "write evals", "test this agent", "evaluate my agent", "bootstrap an eval…
