Install

Skills CLI

npx skills add udaysharmadev/Gravitas

Asks which skills and agents to install. Just one: npx skills add udaysharmadev/Gravitas --skill gravitas-perf — add -g for every project.

Claude Code

git clone https://github.com/udaysharmadev/Gravitascp -r "Gravitas/plugins/gravitas-perf" ~/.claude/skills/

Copies the gravitas-perf skill into ~/.claude/skills/ for every project (use .claude/skills/ for one project). Repeat for the other skills listed below.

Plugin

/plugin marketplace add udaysharmadev/Gravitas

Run inside Claude Code if the repository ships a plugin marketplace, then pick plugins from /plugin.

Skills can run code on your machine — read the SKILL.md first.

What it does

In the author's own words, from each skill's SKILL.md.

  • gravitas

    Use for software implementation, debugging, refactoring, review, migration, and other repository-changing engineering work where correctness must be verified. Enforces scoped reconnaissance, adaptive planning, evidence-backed verification, requirement tracking, failure recovery, and budget-aware delegation. Model-agnostic reliability runtime for coding agents -- measured, not claimed.

Review before you install

A skill is a set of instructions and scripts your agent will follow, and it can run code on your machine. Read the SKILL.md and any scripts first — this listing is not a security review.
