Gtoolkit

Drive a running Glamorous Toolkit (GT) from swamp — and so from Claude.

GT ships its own MCP server (GtLMcpServer) with the tools of its LLM harness. This model starts GT with that server on and talks to it; it does not reimplement GT. Methods:

• start / stop / status — launch GT with the MCP server (idempotent), quit it (optionally saving the image), report reachability, tool count, open windows and GT processes.
• eval — evaluate Smalltalk; the result lands in GT's object storage and comes back with an objectId, class, print string and its views.
• view — render any Phlow view of a stored object (list, columned list, tree, text) to rows, through Phlow's declarative specifications.
• open — open row N of a view, as a click in GT would; a new objectId.
• inspect — open a GT inspector window on an object, for the human.
• screenshot — PNG of a GT window or of one view rendered offscreen, for views that are pictures (graphs, explicit views).
• tools / tool — every tool GT's server exposes: class and method search, Lepiter pages and snippets, compiling methods, running examples.

Every caller value that becomes Smalltalk is quoted as a string literal or checked against a strict identifier/selector/object-id grammar. Large results travel through files, since GT truncates print strings at 50 000 characters.

• The bundled gtoolkit skill is now published with the extension (the manifest lacked skills:).
• Skill references: pharo-syntax.md (Smalltalk for evaluations), gt-apis.md (Phlow views, examples, Lepiter, the UI thread, Brick widgets, windows and screenshots, external processes, saving) and pitfalls.md (every failure seen driving GT, with the fix).
