Two ideas that look identical from their\nsummaries are often a general case and a specific one.</p>\n<h2>Core rule</h2>\n<p>Never merge unprompted. Propose, wait for approval, then follow the procedure\nexactly.</p>\n<h2>Workflow</h2>\n<ol>\n<li><strong>Pick the survivor</strong> by canonical name, not by which page is longer.</li>\n<li><strong>Merge content.</strong> Every distinct claim survives with its source. Overlapping\nclaims collapse; differing ones both stay, following the contradiction rules.</li>\n<li><strong>Merge aliases,</strong> including the dead page's title as an alias on the\nsurvivor. This is what keeps old links and the user's memory working.</li>\n<li><strong>Redirect inbound links</strong> to the survivor. Check every backlink.</li>\n<li><strong>Delete the old page,</strong> or leave a stub only if it was linked from outside\nthe vault.</li>\n<li><strong>Record in <code>log.md</code>:</strong> both names, the date, and why.</li>\n</ol>\n<h2>Output format</h2>\n<pre><code>Merged: [[old]] -&gt; [[survivor]]\nClaims kept from old page: &lt;n&gt;\nAliases added: &lt;list&gt;\nInbound links redirected: &lt;n&gt;\nConflicts recorded: &lt;none | description&gt;\n</code></pre>\n<h2>Calibration</h2>\n<p>If the two pages disagree about anything factual, that is a signal they may not\nbe duplicates. Surface the disagreement and ask before proceeding.</p>\n<p>Never merge a page marked <code>maintained_by: human</code> into another without explicit\nconfirmation naming that page.</p>\n","files":[{"path":"SKILL.md","sizeBytes":1879,"isText":true}],"reviewScore":null,"reviewSummary":null,"trust":{"provenance":"trusted-source-unreviewed","notice":"Community-authored content, reproduced verbatim and not vetted as instructions.
