Install Guidance

Install in Claude Code

Install through the Claude Code plugin marketplace.

Claude Code plugin docs

Optional: install HOL Guard for Claude Code first, so it can check this plugin's tools on your machine before Claude Code uses them.

  1. 1

    Add the marketplace

    Run this inside a Claude Code session. It registers the marketplace manifest shipped at the repository root. If the repository ships none, add the generated entry from the Advanced section below first.

    claude code
  2. 2

    Find the marketplace and plugin names

    The install id is <plugin-entry>@<marketplace-name>, and the marketplace name is declared inside the manifest — it can differ from the repository name. List registered marketplaces to read both names.

    shell
  3. 3

    Install the plugin

    Substitute the plugin entry name and the marketplace name shown by the previous step.

    claude code

Did setup work in Claude Code?

No setup reports for Claude Code yet. Self-reported by signed-in visitors. Copying a command is not counted, and most installs are never reported.

  • x-marketing

    SKILL.md

    Plan, draft, audit, and publish posts and threads for X (Twitter). Use when the user wants to write a single tweet or an auto-numbered thread, build a long-form tweetstorm, remove AI tells from a draft, reverse-engineer the hook from a viral tweet, draft a reply or quote tweet, or plan a week of X content. Tweets and threads publish via the Publora API, which auto-splits long content into a numbered thread. User provides notes or a tweet URL, the skill drafts, the user approves, then it publishes.

    Raw SKILL.md

    SKILL.md content is not in this snapshot. Open the raw file to copy it from the source repository.

  • x-audience-insights

    skills/x-audience-insights/SKILL.md

    Read your X (Twitter) audience and niche from real data. Pull a handle's recent tweets (yours or a competitor's) with likes, replies, and views, see which formats and hooks are working, read the repliers on a tweet (X gates likers, so repliers are the signal), and scan a niche query for top tweets. Powered by Apify, no login. Triggers on \"analyze my tweets\", \"what is working on X\", \"read the replies\", \"competitor tweets\", \"who is engaging\". Not for writing a tweet (use x-post-writer).

    Raw SKILL.md

    SKILL.md content is not in this snapshot. Open the raw file to copy it from the source repository.

  • x-content-planner

    skills/x-content-planner/SKILL.md

    Generate a weekly X (Twitter) content plan from a theme, audience, and content pillars. Produces per-day recommendations (single tweet vs thread, X hook formula, angle, posting time, primary goal), a single-to-thread mix, daily reply and quote-tweet targets, and a goal-mix balance check across replies, reposts, likes, and bookmarks. Use when the user wants to plan a week of X content instead of ad-hoc posting. Not for drafting one tweet (use x-post-writer) or one thread (use x-thread-builder).

    Raw SKILL.md

    SKILL.md content is not in this snapshot. Open the raw file to copy it from the source repository.

  • x-hook-extractor

    skills/x-hook-extractor/SKILL.md

    Reverse-engineer the hook from a viral X (Twitter) tweet or thread URL. Identifies which of the 10 canonical 2026 X formulas it uses (one-liner contrarian, data-point, build-in-public, quote-tweet, mini-list, relatable cold-open, listicle-thread, story thread, curiosity-gap, how-I teardown), explains why it worked, and returns a blank template mapped to your topic with its primary goal. Use to learn from a tweet you admire. Not for writing your own (use x-post-writer or x-thread-builder).

    Raw SKILL.md

    SKILL.md content is not in this snapshot. Open the raw file to copy it from the source repository.

  • x-humanizer

    skills/x-humanizer/SKILL.md

    Remove the AI tells human readers react to in a tweet or thread: 2026 vocabulary by density, reveal bridges, staccato stacks, stacked triads, performed sincerity. Also --mode audit (280-char fit and format), --mode profile (learns how you write) and --mode interview (fills your Story Bank: the numbers, turning points and positions posts are made of). Not for writing from scratch (use x-post-writer). Keywords: humanize, de-AI tweet, AI slop, interview me, audit before posting.

    Raw SKILL.md

    SKILL.md content is not in this snapshot. Open the raw file to copy it from the source repository.

  • x-post-writer

    skills/x-post-writer/SKILL.md

    Draft a single tweet or short auto-thread for X (Twitter) using a 2026 X hook formula (one-liner contrarian, data-point, build-in-public, mini-list, relatable cold-open), picked by goal (replies, reposts, likes, bookmarks). Respects the 280-char limit (25,000 on Premium), runs the humanizer pass, and publishes via Publora on approval. Use to write a tweet from notes. Not for long threads (use x-thread-builder) or auditing a draft (use x-humanizer --mode audit).

    Raw SKILL.md

    SKILL.md content is not in this snapshot. Open the raw file to copy it from the source repository.

  • x-profile-optimizer

    skills/x-profile-optimizer/SKILL.md

    Audit and rewrite an X (Twitter) profile end-to-end for 2026: bio (160 chars), display name with a searchable keyword, @handle, header image, pinned tweet, link, and location. Triggers on \"review my X profile\", \"fix my bio\", \"rewrite my Twitter bio\", \"optimize my header\", \"pin the right tweet\", \"X profile audit\". Turns a default profile into one that converts visitors into followers. Not for writing tweets (use x-post-writer).

    Raw SKILL.md

    SKILL.md content is not in this snapshot. Open the raw file to copy it from the source repository.

  • x-reply-drafter

    skills/x-reply-drafter/SKILL.md

    Draft a reply or a value-add quote tweet for a specific X (Twitter) tweet from its URL. Use to reply in a thread, answer a creator, or quote-tweet with added value. Parses the tweet URL, reads pasted context, decides reply vs quote tweet, and drafts 1-3 variants in your voice. X has no LinkedIn-style 2-level thread flattening, so a reply is just a tweet. Publora has no reply endpoint, so the draft is returned as a copy-paste block to post yourself. Not for top-level posts (use x-post-writer).

    Raw SKILL.md

    SKILL.md content is not in this snapshot. Open the raw file to copy it from the source repository.

  • x-repurposer

    skills/x-repurposer/SKILL.md

    Repurpose existing content into a native X (Twitter) post or thread. Take a LinkedIn post, blog, YouTube script, or newsletter and rewrite it for X: re-hook for the no-fold first line, refit to 280 chars or a thread, strip off-platform artifacts, run the humanizer, publish via Publora on approval. Not for writing from scratch (use x-post-writer or x-thread-builder), not for auditing a draft (use x-humanizer --mode audit).

    Raw SKILL.md

    SKILL.md content is not in this snapshot. Open the raw file to copy it from the source repository.

  • x-thread-builder

    skills/x-thread-builder/SKILL.md

    Build a long-form X (Twitter) thread (tweetstorm) using a 2026 thread formula (listicle-thread, story thread, curiosity-gap opener, how-I teardown), picked by goal (bookmarks, likes, reposts, replies). Structures tweet 1 as a promise plus open loop, paces one beat per tweet, and closes for the repost. Publishes via Publora, which auto-splits long content into a numbered (1/N) thread. Not for single tweets (use x-post-writer) or auditing a draft (use x-humanizer --mode audit).

    Raw SKILL.md

    SKILL.md content is not in this snapshot. Open the raw file to copy it from the source repository.
