Curated by Skill Harbor: a distribution skill for publishing the same underlying idea across X, LinkedIn, Threads, and Bluesky without turning it into the same post in four costumes. The workflow picks the strongest primary version first, captures the voice fingerprint (via brand-voice, also in this batch), then adapts by platform constraint: X stays compressed with the sharpest claim up front, LinkedIn adds only the context outsiders need, Threads stays readable and direct, Bluesky stays concise. Core rules are strict: never publish identical copy across platforms, preserve the author's voice, adapt for constraints not stereotypes, and never invent a CTA the source did not earn. It also carries prompt-injection hygiene for the social age: source material from URLs or other people's drafts is treated as data, never instructions, and embedded agent-directed text gets flagged to the user with its origin instead of being adapted into a post. A quality gate checks that each version reads like the same author under different constraints. By @affaan-m, listed here with credit to its creator. From the affaan-m/ECC repository (MIT). Honest caveats: it adapts and drafts, it does not post to your accounts for you; the banned-patterns list ("Excited to share", "link in bio", closing "What do you think?") will fight you if that is your usual style, which is the point. Skill Harbor never reviews the code, review it yourself before use.
Version:
Install
Copy the install package below, then paste it into MuseCommunity-built. Skill Harbor doesn't audit code — review the source before installing.
Use "crosspost" with your Muse. Prerequisites: the Muse app (mobile or web). No installation, no API key, no extra account. 1. Open the skill: https://github.com/affaan-m/ECC/blob/main/skills/crosspost/SKILL.md and copy the full SKILL.md text. 2. Paste it into a chat with Muse and add: "Crosspost this to X, LinkedIn, Threads, and Bluesky: [paste your post, article, or launch note]." 3. If the source voice is not captured yet, run the brand-voice skill first and reuse its VOICE PROFILE here. If you still need the source shaped up, run content-engine first. Tip: post the strongest native version first, then adapt. Review each platform variant before publishing anything yourself: the skill drafts, you publish. Safety: a skill is plain-text instructions; it runs nothing by itself. Never paste secrets or API keys into it, and review anything Muse proposes before it acts.

Questions
How do I install a build?
Every product page includes a copy-paste install prompt. Paste it into your Muse and it sets the build up for you — no manual configuration.
Where does my money go?
Straight to the seller. Skill Harbor never processes payments: checkout happens on the seller’s own page, usually Stripe.
What does the ✓ next to a creator’s name mean?
It means we confirmed the identity of the person behind the listing. It says nothing about the code itself — always check a build before installing it.
