Shift 0.2.1

A packaging release. The v0.2.0 tarball was 20 MB, almost none of it Shift: brand and interface imagery, design mocks, and the built website, all downloaded by every install to compile 700 KB of Scheme. A .gitattributes keeps the repository's own working material out of git archive, and six unreferenced TUI mocks are gone from the repository as well. The tarball is now about 560 KB and carries the prose in docs/ unchanged, so the RFCs that explain Shift still come with it.

No behaviour changes. Install with brew install thrashr888/tap/shift.

Shift 0.2.0

Plugins can give the model a verb without shipping code. A declared tool is a JSON Schema over an argv template, or over read with its path fixed; calling one is rewritten into that built-in's call before the policy sees it, so it carries no authority of its own and a plugin cannot widen its own by wrapping a command. Pane rows can act: a label bound to a run, a declared tool, or a workflow whose checks decide whether the work was earned. Two plugins join the bundle — kanban, a per-project board kept as one file the pane and the agent share, and shift-dev in this repository's own checkout.

Skills are searched rather than described. The system prompt used to carry every skill's description in every request; it now names them and the skill tool takes a query. With all bundled plugins on, the prompt went from 4,956 characters to 910. Oversized tool output is written whole to the session folder and returned as a head, a tail and a path, instead of being cut off where the tail is. The compaction summary is bounded, and every receipt now reports price-weighted cost by billing type, with rates configured rather than compiled in so none can go stale. --resume takes a session's id as well as its name.

Install with brew install thrashr888/tap/shift.

Shift 0.1.3

Plugins: folders of data that bundle MCP servers, skills, panes, themes, allowlist proposals, 1Password secret sources and live-image artifacts, on by default and scoped per project or user. Seven ship bundled: agentkernel, cider, cortex, alchemy, allbeads, tauri-browser and onepassword. Install with brew install thrashr888/tap/shift.

Shift 0.1.2

Removes the old Python MCP supervisor and the last compatibility shims; the README opens with the Homebrew install. Install with brew install thrashr888/tap/shift.

Shift 0.1.1

The command is now shift-agent (shift is a shell builtin). The stdio MCP transport and bin/shift-mcp are gone: each session serves MCP over HTTP on its own port. Install with brew install thrashr888/tap/shift.

Shift 0.1.0

First tagged release: the live Guile harness with the curses TUI, coding workflow, skills, background jobs, MCP client and server, the autopilot judge, and agentkernel sandbox routing. Install with brew install thrashr888/tap/shift.
