Premier is a local-first agent reporter. One PATH-installable binary:

  1. Records process stdout/stderr into a portable .atrace artifact
  2. Collects typed multi-actor events (agents, models, tools, approvals) over a loopback collector
  3. Serves an embedded investigation viewer — no monorepo, no Node, no separate web app at runtime

Why it exists

Agent runs fail in ways logs cannot explain: which actor delegated, what model was told, which tool returned the bad value, who approved a write. Premier keeps evidence — causal parents, spans, links, status, duration, and structured payloads — so you can investigate instead of re-running and hoping.

Honest scope

  • Process-only record always captures terminal I/O.
  • Full multi-actor investigation requires emitters (premier emit, SDK, or HTTP to the collector).
  • The viewer is embedded in the binary after install — strangers on PATH do not need this checkout.

Start Install

Put premier on PATH with an embedded viewer in one script.

 Start Quickstart

Demo, record, open, and list — the first ten minutes with Premier.

 Record Record

Capture process I/O and spin up a private local collector for agent events.

 Emit Emit events

Attach typed multi-actor evidence via CLI, SDK, or HTTP.

 Emit SDK

First-party TypeScript emitter and shell helper for agent runtimes.

 Integrate Provider adapters

Capture native JSONL from Claude, Codex, Grok, Gemini, and OpenCode without hand-writing every event.

 Viewer Viewer

Investigate runs with timeline, actors, architecture, analytics, and integrity.

 Operate Security model

Trust boundaries, redaction, tenant isolation, transport protection, and data-at-rest responsibilities.

 Operate Secure deployment

Serve Premier over native TLS with scoped tenant credentials and explicit operational boundaries.

 Operate Verify a release

Authenticate Premier's Sigstore identity before trusting checksums or installing an archive.

 Reference CLI reference

Every premier subcommand for production PATH use.

 Reference Trace schema

Stable event envelope, causal fields, manifest metadata, event families, and compatibility rules.

 Reference Troubleshooting

Diagnose missing events, adapter output, auth, TLS, damaged traces, and viewer connectivity.
