Upgrade the agents runtime stack to the renamed Earendil Works
pipackages and refresh the built-in Codex defaults to GPT-5.6 models. Users keep the same agents APIs, while the repo stops depending on deprecated@mariozechner/*packages in the core agents packages and affected examples.Root Cause
The upstream
pi-agent-core/pi-aipackages moved from@mariozechner/*to@earendil-works/*, and the newerpi-airelease carries the latest OpenAI SDK and Codex model catalog. The newpi-airoot entrypoint also moved away from the legacy global helpers this repo still uses, so the migration needs the package rename plus the compatibility entrypoint.Approach
@earendil-works/pi-agent-core@^0.80.5@earendil-works/pi-ai@^0.80.5pi-aihelpers from@earendil-works/pi-ai/compatwhile leaving a full non-compat migration out of scope.pi-ai@0.80.5:gpt-5.6-terragpt-5.6-lunagpt-5.6-terraandgpt-5.6-solProviderIdrather than only known built-ins.pi-agent-coredependencies from the agents examples and use@electric-ax/agents-runtime's exportedAgentTooltype instead.Key Invariants
getModel,getModels,streamSimple, orcompleteSimplecontinues to use the compatibility API.ProviderId.distfiles are not committed; package builds regenerate them.Non-goals
@earendil-works/pi-ai/compatin this PR.distartifacts.Trade-offs
Using the compat entrypoint keeps this PR focused on the package/model upgrade and avoids mixing in a larger ModelManager/provider-collection migration. The downside is that a future PR still needs to migrate to the new root
pi-aiAPI, but this preserves behavior while unblocking the latest OpenAI/Codex catalog.Verification
Passed:
Attempted, but blocked by unrelated/pre-existing workspace/build-order or environment type issues:
Observed failures included missing workspace package/type resolution for
@electric-sql/client/@electric-ax/agentsbefore package builds, and existingprocess.loadEnvFile/import.meta.dirnametype support issues in examples.Also ran:
