Tech Leads Club Agent Skills Surges as Verified Skill Registry

The tech-leads-club/agent-skills repository surged onto GitHub Trending on 14 September 2026 with roughly 265 stars in a single day and about 5,832 stars overall, according to page fetches the same day. The project markets itself as a secure, validated skill registry for professional AI coding agents—naming Antigravity, Claude Code, Cursor, and GitHub Copilot among target hosts—rather than as a one-off prompt pack. Its README highlights a Snyk agent-scan statistic that more than 13 percent of marketplace skills contain critical vulnerabilities, then positions Tech Leads Club skills as verified, tested, and safer to adopt. Distribution is via the npm package @tech-leads-club/agent-skills on Node.js 22 or newer, with TypeScript sources and documentation at tech-leads-club.github.io/agent-skills/.

Why skill registries became a security story

Agent "skills" are packaged instructions and resources—effectively plugins—that teach coding assistants workflows and specialized knowledge. As marketplaces multiply, install convenience collides with supply-chain risk: a skill that can read repositories, run shell commands, or call MCP tools is a privileged extension. Snyk's agent-scan finding that over 13 percent of sampled marketplace skills carry critical vulnerabilities gave registry maintainers a concrete threat number to organize around. Tech Leads Club's pitch is therefore less about inventing the skill format and more about curation, validation, and a professional-facing catalog.

MCP server support noted in the README extends that pitch into the protocol layer many IDE agents already speak. A registry that can describe skills and expose MCP-compatible surfaces sits closer to how Cursor, Claude Code, and Copilot-class tools actually load capabilities. That does not make every listed skill automatically safe; it does explain why a verified-registry narrative is resonating on a September trending chart crowded with agent harnesses. Prior PromptCrates coverage of Superpowers on GitHub trending and the ECC agent harness maps the adjacent skill-pack and harness wave this repo is joining—not duplicating.

For engineering leads, the decision frame is procurement. Unverified marketplace skills resemble unreviewed browser extensions: high leverage, unclear provenance. A registry that claims testing and validation is selling trust process, which buyers should still audit. Star velocity—hundreds in a day toward a mid-four-digit total—shows demand for that trust narrative even before every enterprise security team finishes its own review.

How Tech Leads Club sits beside other trending skill repos

September's agent-skills cluster is not a single winner. Ponytail's agent-skills trending coverage and Alibaba's page-agent show parallel bets: some projects package workflows, others embed GUI control, others harden harnesses. Tech Leads Club's differentiation in its own words is the validated registry for professional coding agents, npm distribution with a Node 22 floor, and explicit vulnerability statistics as marketing contrast.

That Node baseline matters operationally. Teams stuck on older LTS lines will need an upgrade path before @tech-leads-club/agent-skills enters CI. TypeScript source helps auditability relative to opaque binaries, but skills that ultimately instruct models remain prompt-level artifacts: reading the package is necessary and not sufficient. Documentation on the GitHub Pages site is the onboarding surface for leads who discover the repo from Trending rather than from an internal platform team.

Security reviewers should treat the 13 percent Snyk figure as motivation, not as a certificate that Tech Leads Club's catalog is vulnerability-free. Ask which tests run, whether skills are sandboxed, how updates are signed or pinned, and what happens when a skill requests broader MCP or filesystem scopes. The trending spike creates the right moment for those questions while the README claims are still top of mind.

What the 14 September snapshot means for teams

The newsworthy event is demand for curated agent capabilities with a security story attached. Roughly 265 stars in a day and about 5,832 total put tech-leads-club/agent-skills firmly on the mid-September radar beside other skill and harness repos already covered on PromptCrates. Teams should evaluate it as a registry candidate—compare skill quality, update cadence, MCP integration, and vulnerability response—not as a mandatory install from a trending badge.

Documented facts for editors remain bounded by the 14 September page fetch and project materials. The repo tech-leads-club/agent-skills trended with on the order of 265 daily stars and roughly 5,832 total; it targets professional coding agents including Antigravity, Claude Code, Cursor, and Copilot; it cites Snyk's finding that over 13 percent of marketplace skills have critical vulnerabilities; it ships as npm @tech-leads-club/agent-skills for Node 22+ TypeScript; docs live at tech-leads-club.github.io/agent-skills/; and MCP support is noted in the README as part of the packaging story.

Enterprise teams that already restrict model providers now face a second supply chain: the skill files and MCP servers that teach agents how to touch production systems. A registry that advertises validation and security review is responding to that risk narrative, whether or not every claimed check is independently audited yet. The Snyk marketplace finding that more than 13 percent of scanned skills carried critical issues is why a curated npm package can trend even when star counts are modest compared with mega-repos.

Operators should still verify what "validated" means in practice—static analysis, human review, runtime sandboxing, or all three—before treating any registry as a default allowlist. The September 14 surge is a signal that developer attention is moving from raw agent harnesses toward the plugins those harnesses load. That is healthy pressure on authors to ship safer skills, and on buyers to demand receipts.
