This skill treats source fidelity as a first-class constraint.</p>\n<p>It was derived from a repeatedly used private workflow, then stripped of personal voice rules, account data, internal project routing, real post history, private analytics, and platform-specific assumptions.</p>\n<h2>What it handles</h2>\n<ul>\n<li>Single posts</li>\n<li>Quote posts</li>\n<li>Replies</li>\n<li>Explicit threads</li>\n<li>Launches and announcements</li>\n<li>Personal stories and milestones</li>\n<li>Fresh-angle repurposing</li>\n<li>Claim verification and unsupported-claim blocking</li>\n<li>User-supplied voice preservation</li>\n</ul>\n<h2>Core rule</h2>\n<pre><code>Sparse source -&gt; concise draft\nRich source -&gt; richer draft\nMissing facts -&gt; verify or stop\n</code></pre>\n<p>The skill never expands sparse notes with plausible implementation details or inferred benefits.</p>\n<h2>Requirements</h2>\n<ul>\n<li>Hermes Agent with local skill support</li>\n<li>Access to primary sources when the requested copy contains current or high-risk claims</li>\n<li>No external Python dependencies for validation</li>\n</ul>\n<h2>Install</h2>\n<p>Install from Hermes Field Kit as a tap using the command supported by your Hermes version, or copy the skill directory into your local Hermes skills tree.</p>\n<p>Linux or macOS:</p>\n<pre><code>cp -R skills/x-post-writer ~/.hermes/skills/\n</code></pre>\n<p>PowerShell:</p>\n<pre><code>$destination = Join-Path $env:LOCALAPPDATA \"hermes\\skills\"\nNew-Item -ItemType Directory -Force $destination | Out-Null\nCopy-Item -Recurse \"skills\\x-post-writer\" $destination\n</code></pre>\n<p>Start a new Hermes session after installation because skill discovery may be cached.</p>\n<h2>Typical use</h2>\n<pre><code>Rewrite this as one X post. Preserve my point and return only the finished copy.\n</code></pre>\n<pre><code>Turn these verified release notes into a five-post X thread. Do not add details that are not in the notes.\n</code></pre>\n<pre><code>Quote this post and explain why it matters. Do not repeat the embedded link.\n</code></pre>\n<h2>Voice customization</h2>\n<p>The public skill has no personal voice profile. It preserves style and phrasing supplied in the request. See <code>references/voice-customization.md</code> for creating a private local override without committing personal preferences to a public repository.</p>\n<h2>Claim handling</h2>\n<p>Risky claims must end as one of:</p>\n<ul>\n<li>verified</li>\n<li>attributed</li>\n<li>user-supplied</li>\n<li>qualified</li>\n<li>removed</li>\n</ul>\n<p>When an unsupported claim is the premise of the requested post, the skill asks for a source rather than laundering the claim into confident copy.</p>\n<h2>Privacy</h2>\n<p>Do not place private analytics, revenue, unpublished product details, customer data, or personal voice profiles in this repository. The skill treats such inputs as sensitive and does not authorize publication.</p>\n<h2>Limitations</h2>\n<ul>\n<li>Writing quality is partly qualitative; deterministic tests cover routing, safety, and structural contracts rather than subjective virality.</li>\n<li>X behavior and limits change. Verify current official sources rather than encoding reach guarantees.</li>\n<li>The skill drafts copy. It does not publish, schedule, scrape, or analyze account performance.</li>\n<li>A source-locked draft may be shorter than requested when the available evidence is sparse.</li>\n</ul>\n<h2>Testing</h2>\n<pre><code>python skills/x-post-writer/scripts/validate_bundle.py\npython -B -m unittest discover -s skills/x-post-writer/tests -v\npython scripts/validate.py\npython -B -m unittest discover -s tests -v\n</code></pre>\n<h2>Version history</h2>\n<h3>1.0.0</h3>\n<ul>\n<li>Initial public release</li>\n<li>Format and source routing</li>\n<li>Source-lock ledger</li>\n<li>Unsupported-claim hard stop</li>\n<li>Generic voice customization guidance</li>\n<li>Behavior cases and contract tests</li>\n</ul>\n","files":[{"path":"examples/routing-examples.md","sizeBytes":1320,"isText":true},{"path":"README.md","sizeBytes":3797,"isText":true},{"path":"references/algorithm-notes.md","sizeBytes":1404,"isText":true},{"path":"references/claim-verification.md","sizeBytes":2304,"isText":true},{"path":"references/formats.md","sizeBytes":2454,"isText":true},{"path":"references/source-routing.md","sizeBytes":1664,"isText":true},{"path":"references/voice-customization.md","sizeBytes":1034,"isText":true},{"path":"references/x-articles-scope-note.md","sizeBytes":423,"isText":true},{"path":"scripts/validate_bundle.py","sizeBytes":3496,"isText":true},{"path":"SKILL.md","sizeBytes":10303,"isText":true},{"path":"tests/cases.json","sizeBytes":5082,"isText":true},{"path":"tests/test_contract.py","sizeBytes":2729,"isText":true}],"reviewScore":null,"reviewSummary":null,"trust":{"provenance":"trusted-source-unreviewed","notice":"Community-authored content, reproduced verbatim and not vetted as instructions.
