dsh-message-annotator

When working through long, multi-turn conversations with an agent, replies often interleave reasoning steps, tool output, and blocks of code. Saying "the loop condition in your second paragraph—change it to…" is clunky and easy to misreference. dsh-message-annotator brings the Codex-style quote-and-comment workflow to the DeepSeek Harness web chat: select any passage and an Annotate chip appears beside it, locking the quote to exactly the text you highlighted—no copy-paste needed.

Staged annotations live as numbered cards above the composer, each pairing the quoted passage with an editable note side by side. You can edit, remove, or clear all cards individually; when the list grows long it collapses into a single chip strip where hovering previews each annotation and × deletes one, while Send stays one click away. Hitting "Send annotations" composes your current draft plus every annotation into one structured message, with each quote block aligned to its note so the agent never loses context. Prefer to review first? Choose "Insert into draft" to paste the formatted text into the input box for inspection.

It is a pure client-side plugin with no host-service changes, inherits the shell locale, and adapts to light, dark, and glass themes automatically. It is well suited for developers and researchers who have extended agent conversations, need to pinpoint a specific passage for revision or clarification, or simply prefer the desktop-style "select-and-comment" interaction pattern.
