- loadCodeApiKey: load CODE_API_KEY once per request, pass to both
checkSessionsAlive and provisionToCodeEnv (was N+1 lookups)
- provisionToCodeEnv/provisionToVectorDB now return fileUpdate objects
instead of writing to DB immediately
- primeResources batches all DB updates via Promise.allSettled after
provisioning completes
- Remove updateFile import from provision.js (no longer writes directly)
Phase 2 fixes for the unified file experience:
- Add code env file staleness detection via batch session checks
(checkSessionsAlive) — groups files by session_id, one API call per
session, skips files updated within 6h safe window
- Parallelize file provisioning across files using Promise.allSettled
- Surface provisioning failures as warnings on InitializedAgent
- Fix temp file path safety (use file_id + extension, not raw filename)
- Fix inconsistent return types (normalize to [] instead of undefined)
- Wire checkSessionsAlive through initialize.js → initialize.ts →
primeResources
Introduces the foundation for a unified file upload experience where users
upload files once without choosing a tool_resource upfront. Files are stored
in the configured storage strategy and lazily provisioned to tool environments
(execute_code, file_search) at chat-request time based on agent capabilities.
Phase 1 - Schema + Server-Side Unified Upload:
- Add FileInteractionMode enum (text/provider/deferred/legacy) to fileConfigSchema
- Add defaultFileInteraction field to EndpointFileConfig and FileConfig types
- Update mergeFileConfig/mergeWithDefault to propagate the new field
- Modify processAgentFileUpload to support uploads without tool_resource
using effectiveToolResource resolved from config (default: deferred)
Phase 2 - Lazy Provisioning + Multi-Resource Support:
- Create provision.js with provisionToCodeEnv and provisionToVectorDB
- Extend primeResources with lazy provisioning step that provisions
deferred files to enabled tool environments at chat-request start
- Remove early returns in categorizeFileForToolResources so files can
exist in multiple tool_resources simultaneously
- Wire provisioning callbacks through initializeAgent dependency injection
