v0.5.4

Added

• BEAM session snapshots now carry activity metadata including last activity time, current activity start time, and turn count.
• BEAM session trees now show token/cost usage summaries and recursive nested child status aggregation.
• Added TUI/session debugging workflow notes for monitored tmux/asciinema playground runs.

Changed

• Elixir tool call previews normalize multiline arguments into a single pi-style preview line.
• Completed BEAM session trees remain transcript-first while live/running snapshots stay widget-only.

Fixed

• Removed repeated live elixir-sessions transcript entries that caused TUI artifacts during subagent startup.
• Fixed nested BEAM session summary branch alignment in compact trees.

v0.5.3

0.5.3 - 2026-06-09

Changed

• Improved extension import readability with runtime-safe #src/* package import aliases.

v0.5.1

pi-elixir 0.5.1

Added

• Hidden /elixir:debug command that writes a snapshot-style diagnostic dump to ~/.pi/agent/pi-elixir-debug.log.
• PI_ELIXIR_DEBUG=1|debug|verbose responsiveness diagnostics with automatic event-loop lag snapshots during active turns.
• Diagnostic timing spans for lifecycle hooks, connection resolution, embedded BEAM startup/ready/error/exit, bridge request handlers, plugin tool hooks, tool calls, and executable skill discovery/materialization.

Changed

• Mix project resolution no longer recursively scans arbitrary nested directories from broad working directories; it now only accepts the current mix.exs or known bundled packages/bridge/mix.exs layout.

Fixed

• Avoided extension hot-path filesystem traversal that could stall pi’s Node event loop and delay interrupt handling when pi was launched from broad monorepo roots such as ~/Development.

Published to npm as pi-elixir@0.5.1.

v0.4.0

Fixed

• Stale Tidewave status listeners could crash Pi after session replacement — status updates are now subscription-based and session-safe (#3)
• pi install command in README (#2)

New

• Recompile changed modules before eval in embedded mode — edited .ex files are now picked up without restarting (#1)

v0.2.0

New

• ETS table inspector — list all tables sorted by memory/size, inspect contents with Erlang match patterns
• OS-assigned ports — embedded server uses port 0 instead of a fixed range, eliminating collisions between concurrent pi sessions

Fixed

• Wrong-server bug — native discovery no longer falls back to a mismatched project's server when app name doesn't match
• sup_tree crash on library projects without an OTP supervision tree

Changed

• Elixir code extracted to .exs files — tool scripts (top, process_info, sup_tree, deps_tree, types, ets) are standalone Elixir files with proper syntax highlighting and editor support
• Codebase split into modules — index.ts (993→79 lines), 13 individual tool files, shared helpers and renderers
• 73 tests — 58 vitest (unit + integration against a real embedded server), 15 ExUnit for Elixir tool scripts
• Tooling — oxlint, oxfmt, vitest

v0.1.0

Initial release.

• 12 BEAM introspection tools: eval, docs, source, SQL, logs, hex search, schemas, supervision tree, process top, process info, dependency tree, type specs
• Auto-connect to running Tidewave instances (probes localhost:4000–4009, matches by app name)
• Embedded MCP server starts automatically for any Elixir project — no config or deps needed. Uses Bandit/Plug when available (Phoenix), falls back to a zero-dep OTP gen_tcp server (libraries)
• Syntax highlighting for Elixir output, SQL results, docs, and logs in the TUI
• Skill that teaches the agent BEAM introspection patterns
