nicobailon/pi-subagents v0.72.0

on GitHub

pi-subagents 0.72.0 makes Pi start faster and makes provider extensions work everywhere pi-subagents calls a model. Startup no longer waits on global agent discovery, and the executor and Fleet now load the first time you use them. The package also stops bundling its own copy of TypeBox, so installs are smaller and Pi no longer warns about the manifest. Async runs are more dependable, especially for child sessions that launch external jobs and for setups where containers share a temp directory.

Highlights

• Pi starts faster with pi-subagents installed.
• Smaller installs: TypeBox now comes from Pi instead of a bundled copy.
• Models from complete provider extensions work in the watchdog, permission checks, and Prompt Audit.
• Other extensions can plug their own inspectors into Fleet.
• Child sessions can start and resume their own external jobs, and /subagent-cost counts every async launch.

Highlights

• Pi starts faster with pi-subagents installed: startup no longer waits on global agent discovery, and the executor and Fleet load the first time you use them.
• The package no longer bundles its own copy of TypeBox, so installs are smaller and Pi stops warning about the manifest.
• Models from complete provider extensions now work everywhere pi-subagents calls a model, including the watchdog, permission checks, and Prompt Audit.
• Other extensions can plug their own inspectors into Fleet.
• Async runs are more dependable: child sessions can start and resume their own external jobs, /subagent-cost counts every async launch, and live runs are no longer marked failed when containers share a temp directory.

Added

• Extensions can register their own inspector providers with the pi-subagents/inspectors helper or the pi-subagents:inspector-register:v1 event. Fleet uses them for inspector actions, while the built-in inspectors and runner controls keep working as before. Thanks to @ninjapenguin for #2482.

Changed

• Pi starts faster with pi-subagents enabled. The foreground executor and the Fleet view now load on first use, which cuts the extension's own startup modules from 264 to 199. Tools, commands, and prompts are registered exactly as before. Thanks to @h4yfans for the measurements in #2480.
• TypeBox is now provided by Pi instead of bundled with the package. Pi no longer warns about the manifest, and the extension, its children, and background runners all use Pi's copy. Thanks to @felipemm for #2454 and #2455.

Fixed

• The watchdog, permission checks, and Prompt Audit now reach models from complete provider extensions (pi.registerProvider(provider)). They used an older lookup that only knew config-style providers, so these calls failed even though ordinary children could use the same model. Thanks to @chem for #2496.
• Model names such as openrouter/auto-beta now resolve when the provider's own model id already starts with the provider name. They used to fail with Unknown subagent model. Thanks to @schmlblk for #2487.
• fast: true accepts any openai-codex/* model instead of only two named models, so newer Codex models no longer fail before launch. Other providers are still rejected. Thanks to @jtabke for #2452.
• Async status shows a child's real context limit once its session starts, including a limit raised by an extension. Thanks to @johnhenaot for #2448.
• Session startup no longer freezes while pi-subagents looks for globally installed agents. The first agent prompt and subagents_enable still wait until discovery finishes. Thanks to @trading-bl for #2474.
• subagents_enable ignores extra arguments instead of rejecting the call. DeepSeek V4.1 Flash sends subagents_enable({ action: "enable" }), which used to fail every time. Thanks to @crusaderky for #2483.
• An older pi-ai installed next to the package no longer turns off on-demand tool loading, so subagent stays hidden behind subagents_enable until it is needed. Thanks to @abdwhb-png for #2471.
• /council works when Pi runs with --no-skills. It now loads its instructions through subagent({ action: "guide", topic: "council" }). Thanks to @felipemm for #2467.
• External-job runs that a child session launches now start instead of staying queued. Thanks to @juanpprieto for #2449.
• A child session can follow up its own external-job runs with resume, and a repeated resume no longer sends the follow-up twice. Thanks to @juanpprieto for #2465.
• A background run that is still working is no longer reported failed when Pi processes in different containers share one PI_SUBAGENTS_TEMP_ROOT. Pi could not see the runner's process from another container and treated it as gone. Such runs now fall back to the usual 24-hour stale check. Thanks to @zeezooz for #2494 and #2495.
• /subagent-cost includes async single, chain, and parallel launches, which it used to report as having no child usage. Thanks to @zeezooz for #2484.
• Awaited workflow children send the subagent:async-complete event without an extra child notification. Thanks to @mmarabel for #2456.
• Worktree labels stay within 256 bytes when shortened in the middle of a multi-byte character, so async status stays readable. Thanks to @chenhaoxiang for #2446.
• A launch blocked by the session's capability ceiling now fails before any fork work starts. It used to branch the parent session or prepare the fork summary first. Thanks to @antonioc-cl for #2481.
• The subagent schema and guides describe preflight, timeout aliases, budget limits, and child extension bindings accurately, and an empty usageBudget is now rejected. Thanks to @amchen2310 for #2473.
• The async workflow widget no longer flickers while the inline Fleet roster is open. Thanks to @gustavo-neiva for #2468.
• subagent_supervisor pending shows each request's question, so you can answer a request after missing its notice (#2460).
