v0.58.0

Pi-subagents 0.58.0 makes child launches easier to compose and easier to trust. MCP tools can now come from more sources, including runtime-registered servers and package/plugin configs. Agent context is smaller by default, with a clear opt-in when a child needs your global context. Detached and recovered workflows now give clearer results, and launch/status output does a better job of explaining what happened.

Highlights:

• Launch MCP tools from runtime-registered servers, Pi package manifests, and Agent Plugin configs.
• Keep agent context smaller by default, with inheritGlobalContext available when needed.
• Recover detached workflows with clearer terminal handoffs and keyed recovery actions.
• See better launch and status diagnostics for workspace, authority, context-window, and cwd problems.
• Use fast OpenAI-Codex launches with priority service tier without losing provider request fields.

Full changelog:

Highlights

• Launch MCP tools from more places, including runtime-registered servers, Pi package manifests, and Agent Plugin configs.
• Keep agent context smaller by default, with an explicit inheritGlobalContext opt-in when a child needs the operator's global context.
• Make detached and recovered workflow results more reliable, with clearer terminal handoffs and recovery actions.
• Show better launch and status diagnostics for workspace, authority, context-window, and missing-directory problems.
• Keep fast OpenAI-Codex launches compatible with priority service tier without losing provider request fields.

Added

• Support direct MCP tool launches from runtime-registered servers.
• Add inheritGlobalContext agent configuration so children can opt into the operator's global context file separately from repository context. Thanks to @hknatm for #1560.
• Add process-local event registration so independent Pi extensions can register runtime agents through the installed owner. Thanks to @fmoda3 for #1533.
• Add advisory launch preflight diagnostics for likely workspace scope and authority mismatches.
• Document per-run thinking suffixes in model-facing subagent guidance. Thanks to @yanqianglu for #1565.
• Document unsupported native child options for external CLI agents in the subagent tool help, packaged guide, and packaged skill.

Changed

• Agents now omit the operator's global context file by default, including existing agents with inheritProjectContext: true; set inheritGlobalContext: true to preserve the previous behavior. Thanks to @hknatm for #1560.

Fixed

• Fail explicitly requested models closed when a cached model exclusion is active, instead of silently selecting a fallback. Thanks to @harpsychord for #1556.
• Preserve fast-mode provider request root fields when adding OpenAI's priority service tier. Thanks to @nothingrotf for #1570.
• Classify workflow budget and timeout stops as partial terminal outcomes while preserving settled child evidence. Thanks to @yceachan for #1530.
• Publish a deterministic terminal handoff with settled child evidence and keyed recovery actions when detached workflow lanes settle. Thanks to @yceachan for #1530.
• Resolve direct MCP tool selections from Pi package manifests and Agent Plugin configs. Thanks to @fmoda3 for #1541.
• Fail closed with a launch diagnostic when configured runtime-style MCP direct-tool selectors cannot be resolved.
• Sync Herdr status after restoring active async jobs, so recovered work appears without waiting for another lifecycle event. Thanks to @vicocamacho for #1553.
• Show task intent and context-window use in compact in-progress async status rows.
• Report deterministic settlement diagnostics when background children fail before required output handoff.
• Auto-resume workflow children once after setup-phase aborts that produce zero usage, preserving the retained transcript instead of rerunning the whole task.
• Finalize detached foreground worktree handoffs after terminal child completion, preserving captured changes before cleanup. Thanks to @jpriverar for #1562.
• Fail native child launches before spawn when the requested local working directory is missing or not a directory, with the requested and resolved paths in the error.
• Map report paths requested in workflow child tasks to the actual saved child output when workflow output routing overrides them.
• Stop same-session workflows recovered after extension reload through the durable control channel.
• Let agents declare extension mutation tools so real non-Git or untracked edits satisfy the implementation completion guard. Thanks to @AlphaGodzilla for #1532.
• Deliver async results from an explicitly replaced predecessor session without accepting unrelated session results. Thanks to @DresvyanskiyDenis for #1531.
• Avoid attributing assistant-issued workflow stops to the user.
