v3.0.0 · full Claude plugin · four generated editions

One Phoenix playbook. Five AI coding runtimes.

Plausible Elixir is not idiomatic Phoenix. phxagents v3 gives Claude Code, Amp, Codex, Pi and OpenCode the same 51-skill field manual. Claude Code also gets the full 26-agent, hooks and orchestration layer.

What changed in v3.

The release is broader than renamed commands. Canonical skills are projected into native package shapes, core workflows are rewritten around each runtime’s tools, and unsupported Claude-only capabilities stay explicit.

Claude orchestration stays native

Claude Code remains the full plugin: 26 named agents, lifecycle hooks, permission settings, root instructions and its specialist fan-out.

Client payloads are untrusted

New LiveView guidance treats phx-value-*, form and hook payloads as user-controlled. Exposed IDs are not flaws by themselves; every event must authorize against server-side state.

Runtime-honest safety

Generated targets never pretend Claude hooks or named agents are installed. Codex alone gains an optional, trust-gated destructive-command safeguard; other enforcement remains deferred.

Learned fixes become real skills

/phx:learn-from-fix can now save package-specific lessons as native personal or project skills, with locked-version lookup and safe shadowing checks.

The portable workflow layer.

These are the workflows v3 explicitly adapts across every generated runtime. Other skills still ship as useful domain guidance, but may retain Claude-specific orchestration references.

  • Investigate + review

    Reproduce before fixing; review changed files without mutating them. Run independent tracks with native workers or sequentially.

    phx-investigate
  • Plan + work

    Keep the canonical plan schema, scratchpad research, task checkboxes and resumable progress.md.

    phx-plan
  • PR review + full

    Preserve read-only triage, explicit mutation approval, bounded retries and the complete gated lifecycle.

    phx-pr-review
  • Trace + audit + research

    Use direct mix xref, five health tracks, and native web or HTTP tools with local-source fallbacks.

    phx-audit

Choose the runtime you already use.

Every edition ships the same canonical skill knowledge. Packaging, invocation, hooks, custom agents and MCP setup follow each runtime’s real capabilities—not a lowest-common-denominator promise.
