1.0.0

Added

• Added skill update to refresh installed AppSignal LLM skills and skill status to list OpenCode, Codex, and Claude installs as current, outdated, missing, or unversioned.

Changed

• The CLI now blocks command execution when GitHub reports a newer major
  appsignal-cli release and shows an upgrade-required message with the
  current and latest versions.

  Patch and minor releases still show a startup warning only, and GitHub
  outages or other non-200 responses still pass silently so the CLI is
  not blocked by GitHub availability.

• appsignal-cli now supports anomaly detection trigger management with triggers list, triggers create, triggers update, and triggers archive.

  This adds CLI workflows for inspecting existing triggers, creating new metric alerts, updating trigger definitions as new versions, and archiving triggers when they are no longer needed.

  The trigger output and shared skill docs also now distinguish clearly between the trigger name, metric name, and description so trigger configuration is easier to understand.

• Added --format as a synonym for the global --output flag, so you can use either name when selecting human or JSON CLI output.

• CLI command failures now show cleaner user-facing error messages
  instead of raw internal error output.

  Unexpected internal failures now fall back to a generic safe
  message by default, while APPSIGNAL_CLI_DEBUG=1 still exposes the
  underlying details for debugging.

• OAuth login now supports custom AppSignal endpoints that advertise RFC 7591
  Dynamic Client Registration.

  When a custom endpoint exposes OAuth authorization server metadata with a
  registration_endpoint, the CLI automatically registers a public client for its
  loopback callback URL and uses the returned client_id for login and token
  refresh. Endpoints without dynamic registration support still fall back to the
  built-in production client ID unless an explicit oauth_client_id override is
  configured.

• The CLI now checks the latest GitHub tag on startup and shows a boxed
  warning when a newer appsignal-cli release is available.

  The warning is only shown when GitHub returns a successful 200
  response with a newer version, so GitHub outages and other request
  failures do not interrupt normal CLI usage.

Fixed

• auth logout now removes the stored OAuth client ID along with the saved
  credentials, so a later login no longer reuses a stale client ID from the
  previous session.
