Observed facts: The repository README says paste-preview renders thumbnails for pasted-image placeholders in the prompt and transcript. It also documents an editor that opens on paste and supports annotations, cropping, and rotation. The project lists macOS, Linux, and Windows support, while thumbnail display requires a terminal with the kitty graphics protocol.
Mechanism: The plugin reads Claude Code's image paste artifacts and presents a visual thumbnail near the prompt, while its editor can produce a marked-up image for submission. This addresses identification and annotation at the point of input rather than changing how the underlying model interprets images.
Why now: Claude Code's CLI can already accept pasted images, but placeholder labels leave users with little visual orientation when several images enter a session. A plugin makes that workflow more legible without requiring a separate desktop interface.
Implication: This is a practical interface-layer addition for teams that pass screenshots or diagrams into a coding agent, but it remains a third-party extension rather than a native Claude Code capability.
Evidence boundary: The source is the project's public README, which documents intended behavior and requirements; it does not independently establish adoption, reliability, or productivity gains.
Watch condition: Watch whether future Claude Code releases expose native thumbnail and annotation controls, or whether terminal rendering constraints continue to shape plugin adoption.
