nicobailon/pi-subagents v0.61.0 on GitHub

This release makes everyday delegation lighter, clearer, and more reliable. Subagent launches and status updates now repeat less text, which helps keep context usage down during longer work. Workflow authors get named resources for clearer permission boundaries, a primary bg_wait tool, and top-level capacity overrides for heavier scripted runs. Recovery is also sturdier when active async status, child reports, or model fallback attempts hit rough edges.

Highlights

Subagent runs use less context and repeat less status text, so everyday delegation is cheaper and easier to scan.
Status, Fleet, widgets, RPC, and background-work views refresh with less duplicated work.
Async recovery is more reliable when active status files, child reports, or provider fallback attempts go wrong.
Workflow permissions are clearer with named workflow resources and bg_wait as the primary background wait tool.
Model listings now show effective models for discovered and runtime-registered agents.

Added

Add extension-owned named workflow resources so permission and policy extensions can distinguish trusted workflow resources from raw scripts. Thanks @mathiasloh for #1751.
Add workflow-only globalConcurrencyLimit and maxSubagentSpawnsPerRun overrides for top-level workflowScript calls. Thanks @RapierCraft for #1760.
Add bg_wait as the primary background-work wait tool while keeping subagent_wait as a deprecated compatibility alias (#1729).

Changed

Show effective model mappings for discovered and runtime-registered subagents through management and /subagents-models. Thanks @RapierCraft for #1732.
Trim default subagent prompt guidelines to five parent-facing entries while keeping advanced workflow details in the packaged guide. Thanks @Ran-Xing for #1746.
Reduce repeated heartbeat status updates during delegated runs while keeping foreground progress and complete terminal responses (#1739).
Clarify that fallbackModels handles provider/model timeouts but not run-level timeoutMs / maxRuntimeMs expiry. Thanks @kaplan-shaked for #1745.
Pass requested session and timestamp context to background-work providers so they can avoid listing unrelated sessions while preserving strict validation (#1737).
Avoid repeated external-run display normalization during Fleet refresh while still validating externally replaced or mutated records (#1736).
Clarify that oracle and top-reasoning models are escalation tools, not routine defaults.
Serve broad RPC status requests from restored in-memory state when safe, while preserving targeted status and transcript behavior (#1735).

Fixed

Isolate corrupt active async status files during restoration so valid runs remain available and corrupt run artifacts are preserved. Thanks @zhexulong for #1756.
Reduce async widget update churn during running workflows by repainting animation ticks without reinstalling the widget and coalescing close status refreshes (#1726).
Avoid repeated staged workflow projection during widget rendering. Thanks @kkkhs for #1730.
Preserve durable file-only child reports and continue read-only workflow review after malformed acceptance metadata (#1724).
Preserve model origins across fallback and fork preparation, so eligible fallbacks work for unavailable configured primaries while invalid explicit models still fail closed. Thanks @xz-dev for #1747.
Stop hidden 125ms spinner redraws while keeping progress refreshes and one-second animation frames (#1747).
