Terse: a Claude Code plugin that halves reply length by cutting filler

Terse, a Claude Code plugin, enforces a shorter reply style by cutting filler, slogans, metaphors and first-person narration. The author says it reduces replies by 46% on Fable 5.1 and 54% on Opus 5.5, measured on 20 prompts against a real codebase. The plugin installs from the Claude directory or GitHub, and its rules apply to replies, documents, commits and subagents.
