Stack Skills
Install Swing’s marketplace so Claude Code and Codex sessions run under six agent guardrail firewalls that block risky tool use, leaks, and off-policy actions while you build or ship.
Overview
stack-skills is a plugin marketplace for the Ship phase that adds six Swing agent guardrail firewalls to Claude Code and Codex CLI to reduce unsafe autonomous actions.
What is this marketplace?
- Six documented agent firewalls packaged for Claude Code workflows
- First-class support badges for Claude Code and Codex CLI
- Guardrails layer on top of normal coding tasks rather than replacing your stack skills
- Open-source Swing skills repo with versioned releases for repeatable installs
- Reduces destructive commands, credential exposure, and off-scope agent behavior during long sessions
- Marketplace bundles 1 plugin advertising 6 agent firewall skills
- Documented agent targets: Claude Code and Codex CLI
Community signal: 35 GitHub stars.
What problem does it solve?
Autonomous coding agents can run destructive commands, exfiltrate secrets, or wander off-scope when guardrails are left to the base model alone.
Who is it for?
Solo builders running long Claude Code or Codex CLI sessions with shell and repo tools who want a lightweight firewall pack without building custom policies.
Skip if: Pure chat-only workflows, teams that forbid agent tool use entirely, or organizations needing enterprise GRC attestation from this bundle alone.
What do I get? / Deliverables
Installed Swing firewalls steer Claude Code and Codex sessions toward policy-safe tool use so you ship changes with fewer agent-induced incidents.
- Six Swing firewall skills active in the agent runtime
- Reduced-risk defaults for shell, repo, and secret-handling agent actions
- Repeatable guardrail setup via versioned marketplace install

Journey fit
Guardrails matter most before risky changes hit production, so Ship → security is the canonical shelf even though firewalls apply in every phase. Swing is policy enforcement for autonomous agents—aligned with secure shipping and safe iteration, not a single frontend or docs task.
How it compares
Agent guardrail firewall marketplace, not a feature generator skill or an MCP server for a single SaaS API.
Common Questions / FAQ
Who is Stack Skills for?
Indie developers on Claude Code or Codex CLI who enable tool-using agents and want The Stack AI’s Swing firewalls to cap risky behavior across coding sessions.
When should I use Stack Skills?
Enable it before agent sessions that edit code, run terminals, or touch secrets—any journey phase where autonomous tools are on, especially before shipping changes.
How do I add Stack Skills to my agent?
Add the Swing skills plugin marketplace for your Claude Code or Codex setup per the repo install docs, then load the six firewall skills into the agent skill path.
