Productivity with Claude Opus 5.5

A Japanese consultant showed presentation slides that open evidence on click and recompute when dragged, achievable by adding one block to a prompt.

A free Claude skill that checks, builds and upgrades skills against Anthropic's skill-writing rules.

Saves and restores window layouts for design, coding, 3D and marketing sessions; built by an indie dev tired of re-arranging apps.

A developer-oriented desktop client built with Claude after existing tools failed their needs; now at 0.2.x after two months of iteration.

A drawable live map of all hosting, domains, SaaS accounts and databases that warns when something expires, built after a customer was the first to notice an outage.

A tool that visualises a project's progress and attributes token spend to each feature or debugging detour, built because daily usage totals did not explain where effort went.
