v0.6.0

v0.6.0

New commands

• setup — generate a Zed / JetBrains agent config with the absolute
  binary path filled in. --write inserts only the new agent_servers entry
  via jsonc-parser, preserving the file's existing indentation and comments
  (no whole-file reflow). Defaults to Claude Code; wraps any agent via
  setup --editor <ed> -- <command>.
• agents — list the built-in agent shortcuts straight from the registry
  (--json for machines).

MCP — now 13 read-only tools

• generate_editor_config — the MCP twin of setup: returns the config
  block to apply (read-only; the connecting agent writes it).
• list_agent_shortcuts — the MCP twin of agents.

Agents

• JetBrains Junie verified — full WebStorm 2026.1.2 turn captured; added as
  the junie registry shortcut (junie --acp=true).

Docs

• Config recipes and the README Quickstart lead with setup; the
  supported-agents section now spells out how to run any agent — verified or
  not — via setup --editor <ed> -- <launch command>.

v0.5.0

What's Changed

• Flag soon-required ACP fields as advisories and resolve agent labels from absolute paths by @maksugr in #7

Full Changelog: v0.4.0...v0.5.0

v0.4.0 — Playhead playback

Reworked session playback, plus new docs and the agent verification sweep.

Playback (recorded / imported sessions)

• Every frame is on screen from the start; a left-rail playhead marks the current position. Frames are no longer hidden until "played".
• Play / Pause / Replay; the scrubber starts at 0; 0.5×–8× speed.
• The timeline follows the playhead while playing (wheel to take over).
• Reload restores position from the URL: scrolls to the selected frame (seq) or the playhead (play); a finished playhead resets to the start. seq wins over play.
• Recorded and imported sessions no longer auto-jump to the bottom on open.
• Playground deep links (?url=…&seq=…&play=…) restore scroll position.

Docs & ecosystem

• docs/session-anatomy.md: how to read a capture (handshake → prompt turn → cancellation), grounded in a real WebStorm ↔ claude-agent-acp session.
• Agent verification sweep across 13 ACP agents; README "Supported editors & agents" tables with per-row status and evidence links; fixtures/drive-full-turn.mjs live smoke driver.

v0.3.0 — Security & quality hardening

Security and quality hardening.

• diff and session-info redact auth headers and proxy tokens by default; pass --raw to opt out.
• The HTTP API and the /replay/:id WebSocket validate the Host header (DNS-rebinding protection); a custom --host bind is allowlisted explicitly.
• Session listing filters (--client, --imported) run in SQL instead of post-filtering.

v0.2.1

Fixed

• Homebrew install no longer ships a broken better-sqlite3 binding.
• CLI prints actionable remediation when the native binding fails to load.

Added

• CI smoke-tests the publishable tarball on linux/macOS/Windows × Node 22/24.

See CHANGELOG.md.

v0.2.0 — Safe-by-default sharing

Redact auth tokens by default across export/UI/MCP + ship static play…

v0.1.0 — initial release

First public release.

A transparent stdio proxy between editor (Zed, JetBrains, Neovim) and ACP agent (Claude Code, Codex, Goose) that captures every JSON-RPC frame, persists sessions to SQLite, and exposes them through a web inspector, a CLI, and a read-only MCP server.

What's in v0.1.0

• Transparent proxy with concurrent capture discovery
• Web inspector: timeline, spec-aware JSON tree, stream clustering
• Spec validation against the official ACP schema (CLI exits non-zero on violations)
• Performance dashboard: per-method p50/p99/max, waterfall, auto-detected insights
• Multi-session diff: frames, metadata, per-method p99 deltas
• Cross-session search, replay, export/import
• Mock primitives for headless CI (mock-agent, mock-editor)
• Read-only MCP server with 11 tools
