SDK's @qvac/inference Version

@qvac/sdk and @qvac/inference expose the same API, so the SDK's own version and its @qvac/inference dependency range share a major and minor. Patch numbers are free on both sides — @qvac/sdk 0.19.4 may depend on @qvac/inference ^0.19.2.

packages/sdk-python (tetherto-qvac-sdk) is generated from @qvac/sdk and publishes at the SDK's version.

The engine is published first

The SDK's committed range is installed from npm by publish-sdk.yml and by the published leg of pr-checks-sdk-pod, so a range naming an unpublished version fails both.

Moving to a new major.minor is two releases:

1. release-inference-<x.y.z> → publish-inference.yml publishes @qvac/inference and tags inference-v<x.y.z>.
2. release-sdk-<x.y.z> → this skill points the SDK at that version, then publish-sdk.yml publishes @qvac/sdk and tetherto-qvac-sdk.

A patch on either side is one release on its own. An SDK patch leaves its range alone; an engine patch is picked up by the existing range with no SDK release at all.

When to use this skill

Applies to the SDK pod (not the agent-stack cascade: cli / ai-sdk-provider / plugins).

Use when:

• User runs /qv-sdk-inference-version directly.
• Auto-invoked by /qv-sdk-changelog when --package=sdk.
• Auto-invoked by /qv-sdk-pr-create when the PR diff touches the version of packages/sdk or its @qvac/inference range.
• Manually, when an @qvac/inference release has shipped and the SDK should depend on it.

What it does NOT do

• Does not open release PRs or publish (see publish-inference.yml, publish-sdk.yml + gitflow).
• Does not release @qvac/inference; it only points the SDK at a version that is already published.
• Does not sync agent-stack packages (/qv-agent-stack-sync).
• Does not auto-commit.
• Does not run in CI. CI checks the shared major.minor on every PR through the SDK's lint (enforce-inference-versions) and installs the range for real on the published leg of pr-checks-sdk-pod; this skill is the fix.

Workflow

Step 1: Confirm the engine version is published

npm view @qvac/inference@<x.y.z> version

An empty result means the engine release has not landed. STOP and release @qvac/inference first (release-inference-<x.y.z>); everything below writes a range that cannot resolve until it does.

Step 2: Point the SDK at that version

From the monorepo root:

node .agents/skills/qv-sdk-inference-version/scripts/set-inference-version.mjs --engine-version=<x.y.z>

Sets packages/sdk version to <x.y.0> and its @qvac/inference range to ^<x.y.z> (~ from 1.0.0 onwards, where a caret would reach into the next minor). For an SDK patch release whose major.minor already matches, add --sdk-version=<x.y.z>.

Other flags: --dry-run, --check (exit 1 on a mismatch). With no --engine-version, the script only checks the current manifest.

Step 3: Sync packages/sdk-python generated client

Requires a venv with gen extras (create once if missing):

cd packages/sdk-python
python3 -m venv .venv
.venv/bin/pip install -U pip
.venv/bin/pip install -e ".[gen]"
.venv/bin/python3 scripts/generate.py
.venv/bin/python3 scripts/generate.py --check

SDK_VERSION is stamped from packages/sdk/package.json, which Step 2 already set. Commit any updates under packages/sdk-python/src/tetherto/qvac_sdk/_generated/.

Step 4: Verify

cd packages/sdk
bun run enforce-inference-versions

This is the same check CI runs inside lint.

Step 5: Review and commit

git status should show (as applicable):

• packages/sdk/package.json
• packages/sdk-python/src/tetherto/qvac_sdk/_generated/**

Commit alongside the release changelog. When invoked from /qv-sdk-changelog, this is part of the release commit; when invoked from /qv-sdk-pr-create, part of the PR's last commit.

When this skill is invoked from another skill

From /qv-sdk-changelog

/qv-sdk-changelog --package=sdk calls this skill after NOTICE generation for sdk. Skip for any other --package value — an --package=inference release does not touch the SDK.

From /qv-sdk-pr-create

If the PR diff touches the version of packages/sdk or its @qvac/inference range, the parent skill prompts to run this skill first. Opt out with --no-sync on the parent skill.

Quality Checklist

• @qvac/inference@<x.y.z> resolves on npm before the range is written
• set-inference-version.mjs reports OK or an apply summary
• packages/sdk version and @qvac/inference range share a major.minor
• Range operator is ^ below 1.0.0, ~ from 1.0.0 onwards
• packages/sdk-python generate.py --check passes
• bun run enforce-inference-versions passes in packages/sdk
• Staged changes are only the version edits (+ the originating edit)
• No CI auto-commits of this skill
