Be Concise — Productivity skill for Claude Code


concise

Concise is a Claude Code, Codex, and omp plugin that catches the agent's own verbosity before a write or GitHub command runs. It also filters test-runner output before the agent reads it.

New here? Start with [plugins/concise/README.md](plugins/concise/README.md).

What it checks

• Comment blocks longer than 2 lines in Write, Edit, MultiEdit, and Codex apply_patch additions
• New files longer than 300 lines
• Inline gh pr and gh issue bodies with more than 1 prose paragraph or more than 3 sentences in a paragraph
• Em dashes and 47 categories of AI writing patterns, both off until you turn them on
• Output from pytest, go test, npm test, Jest, and Vitest; each run's full output is kept in its own log under $TMPDIR, and the path is printed with the filtered output. Claude Code filters a passing run after it ends and leaves failed runs whole. Codex and omp rewrite the command so the filter runs with it

Structured GitHub bodies that use headings and lists are allowed. A denied call includes the exact limit and location. After 2 denied retries for the same target, Concise permits the next attempt and flags it.

Install
