Install

npx skills add mambalabsdev/mamba-labs-skills

As a Gemini CLI extension:

gemini extensions install https://github.com/mambalabsdev/mamba-labs-skills

Or drop any skill folder into ~/.claude/skills/. Every skill is a single SKILL.md and works in Claude Code, Codex CLI, Cursor and other MCP compatible agents.

What every skill does before it returns

• Skills that read live data call the Mamba Labs MCP server (@mambalabsdev/mcp-gtm-suite, pinned to an exact version) with your own Apify token, or a direct Apify script where the actor has no MCP tool.
• Each skill checks its own output with scripts/check-output.py and reports a half empty result as incomplete rather than returning it as finished.
• Skills that send, post, or write stop for your approval first.
• Every skill opens with a Requirements table: each account, key or service it needs, provider by provider, and what each one costs you. The line after each skill below is the same summary.

Shared context

Each skill reads the files its Shared context section names, from BRAND.md, ICP.md and VOICE.md, where they exist, so you stop repeating yourself. brand-context-builder writes all three from one interview and every other skill gets sharper from it.

Review cadence

Every free skill sits on a 30 day review cycle. Fixes and improvements ship as repo updates.
