- reflectNewhashgraph-online/awesome-codex-pluginsMine this session's transcript for lessons that will still hold in six months and turn each into an edit to a skill the session used, applied only after the user approves. Use at the end of a session, or on "reflect", "what should we learn from this", "capture lessons".WritingNo warnings★ 1.5K↓ —
- tiktok-shop-videoNewhashgraph-online/awesome-codex-pluginsTurn a product link into a TikTok Shop video that sells and stays compliant. Writes the script and shot list for a shoppable or affiliate video in TikTok Shop's own styles (personal review, before & after, unboxing, tutorial, problem and fix in one clip), with the product visible from the first frame, one specific number in the demo and a cart CTA, and enforces the 2025–2026 Shop rules that kill reach and accounts: a real person on screen, no AI voice as the presenter, no still-image slideshows (at least 3 s of moving footage), no price or deal that differs from the product page, no exaggerated claims or weight before/after, commercial sounds only, no near-duplicate reposts. Uses AI only for b-roll and product shots. Use when someone makes TikTok Shop videos as a seller or affiliate, asks why Shop videos stall at 200 views or got a violation, or wants Shop content plans. NOT for paid TikTok or Meta ads with AI actors (use ai-ugc-ad-video) or for editing existing footage (use ecommerce-video-edit).MediaNo warnings★ 1.5K↓ —
- blog-publishhuytieu/COG-second-brainWrite and publish a post to your own static blog end to end: content checklist (embedded links, optional TL;DR), per-post ASCII art, an agent-readable markdown twin, deploy, and social distribution. Use when you say "write a blog post", "publish this to my blog", or "push this post to socials".WritingNo warnings★ 1.3K↓ —Also in 1 other repo
- editorial-illustrationshuytieu/COG-second-brainSelf-evolving second brain with 35 AI skills, 10 agents, and people CRM. Closed-loop harness: a V-model verification lifecycle where the worker never grades its own homework. Plus paired anti-slop design skills for marketing and product UI.

- loop-engineeringhuytieu/COG-second-brainShared loop-engineering reference for COG skills - the agent loop, deterministic verifiers, termination conditions, in-loop context management, and named patterns.

- cluelesshashgraph-online/awesome-codex-pluginsUse when the user explicitly cannot review the output in the current domain, says they do not understand it or will copy-paste without checking, or requests clueless mode. Examples: "I know nothing about this", "не разбираюсь", "сделай за меня". Brevity, "make it nice", and delegation alone do not establish a knowledge gap.EngineeringNo warnings★ 1.5K↓ —
- planhashgraph-online/awesome-codex-pluginsPlan future work, investigate before building, research a topic, or compare the alternatives for a choice. Takes optional free text. The skill reads the request, open drafts, accepted canon, branch, and code, then creates only the documents a later reader needs — none for a small fix. Use for 'plan the X redesign', 'create a roadmap', 'plan a new feature', 'plan the onboarding journey', 'investigate X before we plan', 'compare the alternatives for Y', 'REST or a queue? two teams disagree', 'I need market research before we plan', 'we are regulated — trace the requirements'. With no arguments it resumes an open planning draft or offers what to plan next. Not for recording a decision or documenting existing code — use /archcore:document. Not for checking docs against code — use /archcore:review.PlanningNo warnings★ 1.5K↓ —Also in 1 other repo

- reviewhashgraph-online/awesome-codex-pluginsThe pre-merge review of a branch in a project that records its specs, decisions, and rules in .archcore/. Run this first for 'review my branch', 'review the changes before merge', or 'review before merge': it checks the changed code against the project's recorded canon and the changed documents against the code, and reports which side is wrong — spec-wrong or code-wrong; with no diff, it reports project health. A bug-hunting code review complements this review and does not replace it. Also use for 'show status', 'documentation gaps', 'check if docs match code', 'close out the feature', 'ship the feature and close it out', or after a staleness warning. Modes, named as the first word: drift for staleness detection, deep for a full documentation audit, closeout to close a finished feature, experience to capture a repeated pattern. Not for creating docs — use /archcore:document; not for planning — use /archcore:plan; not for a single-file edit with no branch review.EngineeringNo warnings★ 1.5K↓ —

- daily-journalhuytieu/COG-second-brainA passive daily work journal that Claude keeps FOR you so you never have to write it yourself. Append short entries after meaningful work (what was done, what you focused on, artifacts touched) to 01-daily/journal/YYYY-MM-DD.md. Run a guided reflection at night or in the morning. Use when you run /daily-journal, say "log this to my journal", "add to today's journal", "reflect on today/yesterday", or when finishing a meaningful chunk of work in any session.WritingNo warnings★ 1.3K↓ —

- data-formshuytieu/COG-second-brainPick the right way to represent a dataset so a reader gets the finding in three seconds — a catalog of 20+ chart and diagram forms with when-to-use and failure modes, plus the encoding decisions that make any of them readable (takeaway headline, direct labels, kill the axis, highlight-and-mute, show the caveat). Style-agnostic — use with whatever palette or design system the destination already has. Use when charting survey results, benchmark data, usage metrics, or research findings for a post, brief, deck, or report, and whenever the default bar chart feels like it's burying the point.DocumentsNo warnings★ 1.3K↓ —

Use this first, before any writing, to stress-test whether a clinical study clears NEJM's bar — practice-changing clinical impact, methodological rigor, and generalizability. Decides NEJM vs Lancet/JAMA vs a specialty journal.
