Dependencies and reference

Choose the required integration and find guidance for the version you use.

Version: released 1.3.0. Historical instructions for this release. Start with current 1.5.0 guidance.

What a normal 1.3.0 install supplies

Harness requires Python 3.10 or later. Its released package metadata pins these base dependencies. You do not need to install attune-forms separately for the Harness forms journey.

PackagePinned versionUsed for
attune-forms0.17.0Rendered forms and answer collection
attune-rag1.2.0Local source retrieval
attune-verify0.6.0Supported verification checks
mcp2.2.0MCP integration
tiktoken0.12.0Token counting
packaging26.3Version compatibility checks

These are Harness's release pins, not a claim that they are each package's latest version. Independent dependency upgrades require compatibility review. The release package metadata is authoritative.

Add optional integrations only when needed

ExtraRelease dependency pinsBoundary
redisredis 5.3.1Optional Redis integration
voyagevoyageai 0.5.0, lancedb 0.38.0, pyarrow 25.0.1, jsonschema 4.26.0, httpx2 2.13.0Requires a Voyage key; retrieval makes paid calls
memory-nativeanthropic 1.6.0, httpx2 2.13.0Experimental, POSIX-only native memory path
allredis and voyage extrasExcludes experimental memory-native

For example, install 'attune-harness[redis]==1.3.0' in the isolated environment if the requested integration needs Redis. The release guide recommends [all] for the wider qualified integration set; the local examples in this Help Center need only the normal base install. Installing an extra does not grant execution authority or authorize spending.

Integrate with a host

  • Codex plugin and standalone skill: install the host integration separately from the Python CLI, and verify its installed help.
  • Browser companion reference: open existing task forms through the selected interpreter; treat launch URLs as private.
  • CLI integration guide: participant configuration, task execution and MCP setup. Keep Harness and Attune-AI in separate environments because of their MCP SDK pins.

Read guidance for your version

Browser build dispatch and execution resume are unavailable in Harness 1.3.0. Broader navigation/spec editor designs and pending form accessibility changes are not presented as released. The local walkthrough evidence covers synthetic macOS examples; it does not qualify all hosts, Windows, participant quality or paid-provider behavior.

Sources and verification boundary

Behavior baseline: Harness 1.3.0. Follow the installed route help when your version differs. Tests ground behavior; approved project policy and style requirements govern presentation. Resolve source conflicts before revising instructions.
