Post-DevCon 5 Findings

DevCon 5 expanded the public OSDK toolchain beyond app SDK generation.

The clearest pattern is how generation and compile-adjacent layers now show up in public packages: Maker, Maker Experimental, preview converters, OAC wrappers, and the remaining TypeScript discovery boundary.

15 packages tracked 4 seam patterns priority-first package ordering technical notes / package-first view

Key claims

  • Maker is now a broad public ontology-as-code DSL covering authoring, actions, imports, and discovery-related workflows.
  • The biggest visible seam is TypeScript function discovery, which is still not fully packaged as a standalone public workflow.
  • Maker Experimental exposes backend-oriented artifacts and shape generation on top of Maker state.
  • generator-converters.preview is the clearest public bridge from ontology IR to discovery-aware SDK generation.

Working model

  • Author
    Define ontology in TypeScript with @osdk/maker.
  • Compile
    Push ontology state through Maker Experimental or converter layers.
  • Discover
    Discover TS or Python functions where the public seams allow it.
  • Generate
    Emit metadata and SDK output through generator packages.
  • Ship
    Bootstrap apps with create-app and deploy through the OSDK CLI.

high @osdk/generator-converters.preview
preview codegen bridge
 2026-02 0.1.0-beta.2 - preview The clearest public bridge between ontology IR, cross-language function discovery, richer metadata, and SDK generation.
npm source file
high @osdk/maker-experimental
ontology compiler backend
 2025-08 0.6.0-beta.4 - experimental A compiler-flavored V2 path layered on top of Maker state, exposing backend-oriented artifacts and shape generation.
npm source file
high palantir-mcp
wrapper installer
 2025-01 - - mixed A public wrapper package that sets up access to a broader MCP runtime rather than implementing that runtime itself.
npm source file
high @osdk/maker
ontology authoring DSL
 2024-03 0.16.0-beta.9 - mixed The public ontology-as-code DSL; important because it kept expanding from object definitions into actions, imports, discovery, and compiler-facing workflows.
npm source file
high @osdk/cli
deploy and operations CLI
 2023-11 0.32.0-beta.3 - public The operational CLI for deploys and selected generation workflows; most mature on shipping/runtime operations rather than compiler internals.
npm source file
medium @osdk/vite-plugin-oac
OAC build plugin
 2025-06 0.5.6 0.5.6 public The public Vite-facing wrapper around the OAC pipeline, important because it turns ontology compilation into a normal dev-server/build step.
npm source file
medium @osdk/create-app
app bootstrap CLI
 2024-02 2.8.0-beta.15 2.7.5 public The public scaffolding CLI for SDK apps; more interesting for its template/versioning model than for any recent patch bump.
npm latest source file
medium @osdk/language-models
model proxy helper
 2026-03 0.1.0 - public A tiny package, but a clear public signal that Foundry model-proxy access is being normalized around the PlatformClient.
npm source file
medium @osdk/functions-testing.experimental
local testing helper
 2026-02 0.2.0-beta.3 - experimental A local-first mocking package that suggests external function development is becoming a first-class workflow.
npm source file
medium @osdk/foundry.aipagents
generated platform namespace
 2025-01 - - public A generated namespace exposing public resources for agents, sessions, traces, and streaming flows.
npm source
medium @osdk/foundry.thirdpartyapplications
generated platform namespace
 2025-01 - - public A generated namespace that underpins public site deployment workflows and makes the OSDK CLI's deployment layer easier to understand.
npm source
medium @osdk/generator-converters
metadata conversion layer
 2025-01 2.8.0-beta.15 2.7.5 public The normalization layer where ontology and query semantics become SDK metadata; this is where semantic support tends to land before it becomes visible in higher layers.
npm latest source file
medium external-systems
python connectivity sdk
 2025-01 - - public The Python connectivity layer for proxied external sessions, secrets handling, and source-style runtime access.
PyPI source

 2025-01 - - public The Python runtime/tooling layer for compute modules, focused on annotations, schema inference, bootstrapping, logging, and resources.

Maker TypeScript Discovery Boundary

In the public materials reviewed for this repo, Maker exposes a function-discovery path whose standalone install workflow is not clearly documented.
