system_prompts_leaks
Extracted system prompts from Anthropic - Claude Fable 5, Opus 5, Claude Design, Claude Code. OpenAI - ChatGPT GPT-5.6-Sol, Codex. Google - Gemini 3.5 Flash, 3.1 Pro, Antigravity. xAI - Grok, Cursor, Copilot, VS Code, Perplexity, and more. Updated regularly.
I compared the Claude Opus 4.8 and 5 system prompts, as well as the Claude Code Opus 4.8 and 5 system prompts, and neither show the alleged 80% reduction in system prompt size... Is the Claude Code system prompt leak incorrect? Do I not know what 80% looks like? Why such a large lie (so it seems)?

obsidian-smart-connections
Find related notes and excerpts while writing. Your link building copilot displays relevant content in graph + list view. A local embedding model powers semantic search. Zero setup. No API key.
SmartConnections but heads up, Connections Pro asks $300/year, or, more for the plugin than for an LLM subscription, more than Microsoft Office for that matter.

-
baoyu-design
Run Claude Design locally as an Agent Skill — Cursor, Claude Code & more. Produce polished UI mockups, prototypes, decks & wireframes as self-contained HTML, without claude.ai/design. Best with Opus 4.8.
Yeah these skills match that list of names, looks like this one may have extracted all of the prompts: https://github.com/JimLiu/baoyu-design/tree/main/skills/baoy...
-
avoid-ai-writing
Skill that audits and rewrites content to remove AI writing patterns. Use it with your favorite agents including Claude Code, OpenClaw, Codex, and Hermes.
I've been looking around for skills that help with improving AI prose, and found these:
(1) Avoid AI Writing - https://github.com/conorbronsdon/avoid-ai-writing
(there is a similar "humanizer" skill that (1) subsumes)
(2) Agent style: https://github.com/yzhao062/agent-style
(3) Journal-adapt (style transfer from your writings): https://github.com/WantongC/journal-adapt-writing-skill
I find it useful to set up dynamic workflow loops with (1) and/or (2) as checkers.
On (3) - I think "style-transfer" that was all the range in image-gen is going to be very useful for prose-generation. Curious if there are other such skills.

Project mention: I Tried and Failed to Rebuild the 1996 Space Jam Website with Claude | news.ycombinator.com | 2025-12-07
Just use Playwright Skill (https://github.com/lackeyjb/playwright-skill). It is a game changer. Otherwise it is Claude the Blind, as OP mentioned.
-
unlazy
Anti-laziness skill for AI agents. Core: the Depth Tree method, which splits a task N layers deep and gives every leaf the full time budget of the whole task, so effort multiplies with depth. Grounded in 2025-2026 research on model laziness, underthinking and premature completion. (by Leonxlnx)

Project mention: How to Stop Your AI Coding Assistant From Being Useless at Specialized Tasks | dev.to | 2026-04-25As your collection grows, structure matters. A pattern I've seen work well — and one used by open-source skill collections like ConardLi's garden-skills on GitHub — is grouping skills by capability domain:

claude-delegator
Delegate tasks to Codex and Gemini directly from within Claude Code. (by jarrodwatts)
I did not invent the delegation layer. claude-delegator is a fork of Jarrod Watts' original (MIT, upstream currently quiet), fully based on his design - I kept the structure and the license.
