- Add .odt (application/vnd.oasis.opendocument.text) as a supported upload format; extract text via JSZip + content.xml parsing - Add attach_document_to_lesson agent tool so the AI can attach an uploaded document to a lesson as a downloadable material - Instruct the agent to create a "Course Materials" lesson (first lesson of the first section) and attach the uploaded document to it on implementation - Suppress hallucinated references: uploaded documents do not count as fetched URLs — omit the References section when no fetch_documentation_url calls were made - Surface specific upload error snackbars (file_too_large, unsupported_file_type) instead of silently logging; fix generic fallback message - Allow typing in the chat textarea while a document is uploading; only block Enter/send, not the whole input - Fix retry endpoint to return the current run instead of erroring when the run is already active (queued/running/waiting_for_input/paused) - Connect @cio/core Redis singleton in the jobs bootstrap so course-generation workers no longer fail with "The client is closed" - Expose documentAssets (assetId + fileName) alongside documentText in AgentContext and pass it through both the chat route and course runner
@cio/core — shared business services
This package holds the business-logic layer that both apps/api (HTTP) and apps/jobs (BullMQ worker) need to call. Anything in here is transport-agnostic: no Hono Context, no ContentfulStatusCode, no c.json, no zValidator middleware. Just functions that compose database queries, apply business rules, and raise AppError on failure.
The name is intentional: this is the core of the platform. The HTTP routes in apps/api and the worker processors in apps/jobs are thin transports over this layer. Anything they share has to live here — otherwise one app ends up depending on the other (apps/jobs → apps/api was the original sin that motivated extracting this package).
What lives here
| Folder | Contents |
|---|---|
src/services/agent |
The durable agent runner, chat-mode tool implementations, planning helpers. |

src/services/lesson |
Lesson read/write helpers. |
src/services/assets |
Asset upload, attach, detach, presign — used by both API routes and worker. |
src/services/jobs |
BullMQ enqueue helpers (e.g. startMediaJob) callable from any service. |
src/services/lesson-language |
Localized lesson content helpers. |
src/utils |
Storage, presigning, sanitization, tinybird, redis helpers. |

Placement rule
┌─────────────────────────────────────────────────────┐
│ Does the function need a Hono Context, or call │
│ `c.json`, or validate a request shape? │
│ │
│ YES → it's a route handler, stays in │
│ `apps/api/src/routes/{domain}/…` │
│ │
│ NO → it's a business service, goes in │
│ `packages/core/src/services/{domain}/…`│
└─────────────────────────────────────────────────────┘
If the function only touches the database and has no business logic, it doesn't belong here either — it goes in packages/db/src/queries/{domain}/. The split is:
- Query layer (
@cio/db/queries): pure SQL/Drizzle helpers, no business rules. - Service layer (
@cio/core/services): composes queries, applies rules, throwsAppError. - Route layer (
apps/api/src/routes): HTTP transport — auth, validation, status codes, response shapes. - Worker layer (
apps/jobs/src/workers): BullMQ transport — pulls a job, calls services, persists outcome.
What does NOT belong here
- HTTP-shaped code (Hono types, response helpers, content-type handling) — keep in
apps/api. - BullMQ worker bootstrapping (Redis connection, worker lifecycle) — keep in
apps/jobs. - Frontend / Svelte / UI primitives — those live in
apps/dashboardorpackages/ui. - Raw Drizzle query functions with no business logic — those go in
packages/db/queries.
Why it isn't called @cio/services
@cio/core is shorter and reads cleaner at import sites (from '@cio/core/services/course/content'). The folder structure makes it obvious that it's a services layer; the package name doesn't need to repeat that.
History
This package was originally extracted as @cio/agent-runtime to hold the durable agent runner and its transitive closure. That closure turned out to be ~80% generic business services that apps/api and the worker both need, so the package was renamed to @cio/core to match its contents. The agent runner (services/agent/course-generation-runner.ts) remains the top-level export for apps/jobs, but it's just one of many services living here now.
