T27F Frontend

Category: Content  ·  Sub-category: content-misc  ·  Last updated:
T27F is t27's frontend -- the one tool through which t27 shows anything visual, made through several tools (spec graph and outline, honeycomb map stills, the t27.ai graph page, particle reels and stills, the hot-reload stream, the claw/t27f check-run), with its surfaces, their status and the intent-to-surface routing in specs/t27f/frontend.t27. Its core is the visual spec of a .t27 file (gHashTag/trinity#1648, RFC gHashTag/trinity#1649). TRI CLAW serves its MCP tools. Use when the user says "t27f", "visual", "visual spec", "show / visualize / draw this spec", "reel", "still", or opens a .t27 file to see its structure. Also runs the topic-map application (gHashTag/trinity#1677) when the user gives a topic or a client brief.
