Use when the user wants to inspect, classify, add, remove, replace, synchronize, or verify labels on a GitHub pull request; require evidence-backed current impact for bug, security, severity, and priority classifications, preserve unrelated labels, plan changes before applying them, and use the bundled REST-based helper for authorized mutations
Use when the user wants a maintainer-quality review of a GitHub PR, actionable findings, blocker or closure recommendations, or explicitly authorized COMMENT-only GitHub feedback; gate deep review on supported-path reachability and evidenced net value, report close/no-merge directly for unreachable or valueless changes, never approve PRs, and use pr-worktree for isolated local checkout
Use when the user explicitly wants to modify an existing GitHub PR as a maintainer and push focused fixes to its head branch; establish the confirmed issue, protected contract, minimal change cone, and verification evidence first; use pr-worktree so the current workspace is not disturbed
Safely rebase an existing GitHub pull request branch onto the latest base branch, resolve conflicts while preserving the PR's intent, rerun focused verification, and optionally update the remote PR branch. Use when the user asks to rebase, sync, refresh, or bring a PR up to date with main or another base branch, especially before merge or after the base branch changed.
Rewrite and polish Chinese technical writing through selective, comparative edits and relevant references, including author-approved samples, before/after pairs, voice profiles, factual sources, and platform examples. Use when the user asks to rewrite, polish, 润色, 改写, 提升吸引力, match their voice or 文风, improve readability, flow, rhythm, viewpoint, or narrative, while preserving facts, narrative ownership, author perspective, and technical substance.
Capture, incubate, and review verifiable content fragments from daily engineering work — debugging findings, experiments, tool comparisons, pitfalls — for future social posts. Use when the user says to save/log/capture a material or experience fragment, asks what content is ready to write, or wants to review accumulated material fragments by topic or maturity.
Draft publishable content from material fragments or raw input into platform-appropriate copy — tweets, HN posts, long-form articles, or blog posts. Use when the user wants to write/draft/compose a tweet, HN post, blog post, or any social content; or when material review produces a draft frame ready for final copy. Triggers: draft, write a tweet, 写推文, draft a post, compose content, 成稿.
Use when any GitHub PR workflow needs to checkout, inspect, review, test, or modify a PR locally without disturbing the current workspace; drive isolated review/fix worktree preparation, status checks, and safe cleanup through the bundled deterministic helper
