The instructions your model reads when the skill loads.
The harness adapters are all the packages/harness-* packages. They each rely on one or more third-party packages for the respective harness's primary SDK. It is crucial to keep those dependencies up to date.
Below you find the instructions on how to update those packages to their latest versions, while adhering to the minimum release age defined in pnpm-workspace.yaml.
Run the following commands to update each harness's primary SDK packages.
devDependencies, while the actual package versions used as dependencies are only relevant to the harness's bridge itself.dependencies.Run these commands exactly as below:
# ACP
pnpm --filter harness-acp update @agentclientprotocol/sdk @modelcontextprotocol/sdk --latest --lockfile-only
# Claude Code
pnpm --filter harness-claude-code update @anthropic-ai/claude-agent-sdk @modelcontextprotocol/sdk --latest --lockfile-only
# Cline
pnpm --filter harness-cline update @cline/agents @cline/core --latest --lockfile-only
# Codex
pnpm --filter harness-codex update @openai/codex --latest --lockfile-only
# Deep Agents
pnpm --filter harness-deepagents update @langchain/core @langchain/langgraph deepagents langchain langsmith --latest --lockfile-only
# GitHub Copilot
pnpm --filter harness-github-copilot update @github/copilot --latest --lockfile-only
# Grok Build
pnpm --filter harness-grok-build update @xai-official/grok --latest --lockfile-only
# OpenCode
pnpm --filter harness-opencode update @opencode-ai/sdk --latest --lockfile-only
# Pi
pnpm --filter harness-pi update @earendil-works/pi-coding-agent --latest --lockfile-only
For the bridge dependencies of bridge harnesses, you must additionally run the following commands. It is important to specify the config.minimumReleaseAge flag in accordance with what pnpm-workspace.yaml defines, because for these commands the --ignore-workspace flag is needed.
Run these commands exactly as below:
