Pi Agent Platform v1.34.1

Piagent asks Studio what it serves, helpers report how their work ended, and Agent Watch learns when a conversation needs you (Agent Studio 0.34, Agent Watch 0.15.9 / Windows 0.1.15).

Changes

• v1.34.0 was tagged but never published: its lockfile named a lightningcss version that does not exist. v1.34.1 is the same release with the lockfile fixed.
• Studio capabilities. Piagent asks GET /v1/capabilities (Agent Studio 0.34+) once an hour per Studio and key, and keeps the answer in ~/.pi/agent/studio-capabilities.json. A newer operation is used only when Studio lists it; an older Studio (404) keeps today's behaviour. memory_ask is offered unless the list leaves memory.ask.v1 out.
• Structured delegation. delegate takes five optional fields beside the brief: target, change, constraints, ownership and acceptance. They head the helper's brief.
• Helper settlements. Each helper attempt reports once, with its own run token, how it ended: succeeded (answered in the form its role needs), failed, cancelled, or unverifiable (no verdicts or findings, or a stale review). The main agent reads Outcome: … first; the receipt line says done, failed, stopped or unverifiable. Studio shows each attempt's ending in Logs → Lượt agent and reads an attempt without a report as unverifiable.
• Review on the diff. In Agent Inspector → Source Changes, click a line number to comment that line. Comments on any number of files go into the conversation's composer as one message with a file:line anchor and the code of each line; a comment whose line has changed since is marked. The review helper's findings (blocking, major, minor) show under the line they name, and findings without a line under the file.
• Conversation states for Agent Watch. The dashboard and the company runtime write each conversation's state (working, waiting for an approval or an answer, done, stopped, failed) under ~/.pi/agent/status/. A file holds the conversation's title and project name, never its preview, prompt or answer. Agent Watch 0.15.9 (macOS) and 0.1.15 (Windows) turn it into notifications.

Tests

• tests/managed-studio-capabilities.test.mjs, tests/managed-helper-settlement.test.mjs, tests/piagent-webui-agent-status-files.test.mjs, tests/piagent-webui-line-review.test.mjs; tests/piagent-webui-session-hub.e2e.mjs comments two files and sends them; tests/managed-delegation-cli.test.mjs checks both helpers' settlements through the production CLI.
