🚫

Bypass Blocked

System-wide blocks are rolling out that prevent the use of --dangerously-skip-permissions and the permissions-bypass setting

Tip: You can ask Claude Code to adjust your permissions — "Allow read and write permissions to my development files in ~/dev on this computer in settings.json"

Today's Topic

Welcome to the Marketplace

The Claude Code Marketplace is a curated registry of plugins that extend Claude Code with new capabilities. Install once, use everywhere. Built by Ally engineers, for Ally engineers.

🔌

MCP Servers

Connect Claude to live data sources and APIs

⚡

Skills

Reusable expertise invoked with /commands

🤖

Agents

Specialist sub-agents for complex workflows

📦

Commands

One-shot actions packaged for quick use

Skills vs Agents: Both are picked up and used automatically by Claude. The difference is that a skill can also be directly invoked with a / command (e.g. /review-mr, /tf:generate), while an agent is spawned behind the scenes when Claude decides it needs specialized help.

  • Releases: develop → main via team MR
  • Two approvals: ETA-PCE + BCF-C3 CODEOWNERS

Commit Standards

CI Validation (Automated)

  • plugin.json exists with required fields
  • Valid semver version in manifest
  • README.md present in plugin dir
  • No Task() in commands
  • No hardcoded MCP URLs in source
  • Semgrep SAST scan passes

Versioning

Every code change requires a version bump in plugin.json (single source of truth). Semver: patch for fixes, minor for features. Do NOT edit marketplace.json directly.
