A large library of 385 business, product, compliance and engineering skills with 906 standard-library Python tools, under a Commons Clause license.
Substantial and script-backed, but the Commons Clause license restricts commercial redistribution and the sheer size calls for installing only the plugins you need.
This is a catalog rather than a single method: 385 skills in 21 domains, 76 expert agents, 26 slash commands and personas such as startup-cto. The biggest groups are Engineering (92), Project Management (70), Marketing (41), C-Level Advisory (31), Compliance and Quality (27), Business and Growth (20) and Legal (17). Most skills pair a long SKILL.md (about 12 KB on average) with three Python scripts that do the scoring or calculation, for example a headline scorer, a channel margin calculator and a commercial policy generator. The README says the scripts use only the standard library, so numbers come from code rather than from the model.
Skills are meant to ask two or three clarifying questions before producing a deliverable. Compliance coverage is a selling point: SOC 2, ISO 13485, MDR, FDA, EU AI Act, NIS2, DORA, HIPAA and GDPR. Install routes include a Claude Code plugin marketplace, an npx installer (@borghei/claude-skills) for Cursor, Codex, Gemini CLI, Copilot and others, an MCP server, and a browser library for copying prompts. We could inspect only three of the 21 domains locally.
385 skills averaging about 12 KB with three helper scripts in the folders we checked, plus 26 eval files across the repo, but references and tests are uneven.
Counted from the repository file tree. How we score depth.
A large set of business-advisory skills whose scripts are offline Python calculators using only the standard library; they read the files you point them at and optionally write an --output file. We hold only a fraction of the repo (3,783 files missing) and did not read most scripts line by line, so this review is partial. Non-Claude installs use an unpinned npx @borghei/claude-skills CLI.
npx @borghei/claude-skills add <skill> (unpinned npm CLI whose code is not in this repo).README.md:31The repository (4079 files) on Oct 29, 2026. Not a full review: 3783 of 4079 files were not downloaded (large repository; we reviewed the skill folders); it contains compiled binaries or archives we cannot read; we read 2 of 119 code files; it relies on code outside the repository: npm package @borghei/claude-skills (README install/search CLI) and the MCP server mentioned in docs/INSTALLATION.md; 3,783 text files of the repository are not in our snapshot (including .claude/agents, marketplace.json, site/ and most SKILL.md/docs); 117 of the 119 listed Python scripts were pattern-searched (imports, subprocess/network/eval/env/file-write calls) but not read line by line; they are not listed under code_files_read.
NVIDIA SkillSpector static scan: 15 pattern hits (Excessive Agency 10, Anti-Refusal 1, YARA Match 1, Privilege Escalation 1, MCP Rug Pull 1, Dangerous Code Execution 1). No SkillSpector summary issues beyond the dossier's grep evidence; word hits such as 'requests', 'subprocessors' and 'https_visible' in scripts are business-domain strings, not network code.
A review, not a certification. Skills change after we check them — read the files before installing.
MIT + Commons Clause — free for personal, educational, open-source and internal business use; cannot be sold or repackaged as a paid product (GitHub reports the license as unrecognized).
Not really. Skills are consultative and ask the user for inputs; there is no unattended loop or stop condition.
A 400+ skill library of agents, personas and commands for engineering, marketing, product, compliance and C-level work, mirrored for 13 coding agents.
107 stack-agnostic skills covering the website lifecycle: brand, design, content, SEO, product, ops and growth, with 516 reference files.
120 marketing skills across seven disciplines (narrative, SEO/GEO, social, email, paid ads, influencer, launch) with scored auditor gates and an optional 8-bot team mode.
A catalog of roughly 2,900 community SKILL.md playbooks, with a local CLI, MCP server and plugin bundles for searching and installing them.
It is a library of 385 skills, 76 agents and 906 Python tools covering engineering, project and product management, marketing, C-level advisory, compliance, legal, HR and more, with versions for Claude Code, Cursor, Codex, Gemini CLI and Copilot.
In Claude Code run /plugin marketplace add borghei/Claude-Skills and then install a set such as c-level-skills or pm-skills. For other assistants the README offers npx @borghei/claude-skills add <skill>, which needs Node 18+.
The README says MIT plus Commons Clause: free for personal, education, open-source and internal business use, but you cannot sell it or repackage it as a paid product. Check the LICENSE file if you are building a commercial offering on top.
Both are large multi-domain collections. Borghei's carries the Commons Clause restriction and leans on compliance and C-level material; compare their licenses and the specific skills you need before installing either.
