            </div><p>記帳大概是最被高估的「好習慣」。它考驗毅力跟自制力，但坦白說一點也不高效——你花在輸入、對帳、分類上的時間，常常比它幫你省的還多。我自己用 Precento 追資產，但每個月的消費明細散在各家銀行的 App 跟信箱裡，想橫向看一眼根本是災難。<a href="https://github.com/kylinfish/mailquill" target="_blank" rel="noopener noreffer ">Mailquill</a> 就是我把「記帳」從毅力題改成 pipeline 題的嘗試。</p>]]></description>

            </div><p>用 Claude Code 同時養好幾個 side project，很快就會撞到一個問題：對話散在每個專案的資料夾裡，你根本記不得上次那段在哪。<a href="https://github.com/kylinfish/claude-code-resume" target="_blank" rel="noopener noreffer ">claude-code-resume</a>（<code>ccr</code>）就是為這個痛點做的——一個指令，跨專案 fuzzy search 所有 Claude Code 對話，選一個直接 resume。</p>
<p>我是在終端機裡過日子的人——<code>vim</code> + <code>tmux</code> + <code>fzf</code> 那一派，多年前就把<a href="/unix-like-develop-env/" rel="">終端機下的開發配置</a>整理成一篇。這麼多年過去，那套工具鏈的品味沒變：一個指令、鍵盤一路到底、不用碰滑鼠、不用切到另一個視窗、丟到 <code>PATH</code> 就能用。ccr 就是照這個老標準，做給現在的 Claude Code 工作流。</p>]]></description>
