蹇硕 / Jian Shuo (late Han)
蹇硕 / Jian Shuo (late Han) enters the wiki through Hanji 943 as the eunuch and military office-holder whom 汉灵帝 trusts with Liu Xie, later 汉献帝, near the end of his life. The source presents Jian Shuo as the first actor to try converting the unsettled succession into force: kill 何进 first, then install Liu Xie.
The plan fails because 潘隐, Jian Shuo’s subordinate and He Jin’s old acquaintance, warns He Jin during the palace summons. Once 刘辩 / 弘农王 has been enthroned, Jian Shuo tries to recover by writing to 赵忠 and other eunuchs, urging them to close the palace gates and strike He Jin quickly.
That appeal exposes his isolation. 郭胜 is tied to the He family and hands the letter to He Jin; He Jin orders Jian Shuo arrested and killed. The source then says Jian Shuo’s palace guard command passes to He Jin, turning a failed succession coup into a major strengthening of the He side before Hanji 944’s anti-eunuch planning.
