bigpowers — Best-in-Class Agentic Skills

61 agent skills for high-integrity, spec-driven, test-first software development by solo developers.

bigpowers provides a prescriptive, vertical-slice methodology for building software with AI agents (Claude Code, Gemini CLI, Cursor, pi). It bridges the gap between raw LLM capabilities and professional engineering standards.

Published on npm: bigpowers@2.0.0

🚀 Quick Start

npm (recommended)

# One-shot setup — downloads, syncs artifacts, and links skills to your tools
npx bigpowers

# Or install globally and run the setup command anytime
npm install -g bigpowers
bigpowers

Both commands sync skill artifacts and link them to Claude Code, Gemini CLI, and Cursor (see Prerequisites).

From source (contributors)

git clone https://github.com/danielvm-git/bigpowers.git && cd bigpowers
npm install          # runs postinstall: sync + link
# or manually:
bash scripts/install.sh
npm run sync

---

🛠 Prerequisites

• Bash: Required for all scripts.
• Node.js: v14+ (required for npm/npx).
• jq: (Highly Recommended) Used for robust configuration of tool settings.
• AI Tools: One or more of:
  • Claude Code
  • Gemini CLI
  • Cursor
  • pi — coding agent harness

🔄 Maintenance (Update & Uninstall)

Update

npm install:

npm update -g bigpowers
bigpowers    # re-sync and refresh symlinks

git clone:

git pull
npm run sync

Install uses symlinks — re-running setup refreshes links without duplicating files.

Uninstall

npm install:

bash "$(npm root -g)/bigpowers/scripts/install.sh" --uninstall
npm uninstall -g bigpowers

git clone:

bash scripts/install.sh --uninstall

Reinstall

npx bigpowers
# or, if installed globally:
bigpowers

---

🔌 pi Support

bigpowers generates pi Agent Skills and prompt templates alongside Cursor and Gemini artifacts via sync-skills.sh.

Install as a pi package

# Clone and sync to generate pi artifacts
cd bigpowers
bash scripts/sync-skills.sh

# Install from local path as a pi package
pi install .

# Or install as a pi npm package (once published with pi-package keyword)
pi install npm:bigpowers

What you get:

• 62 pi skills in .pi/skills/ — loaded automatically into pi's system prompt as <available_skills>
• 62 pi prompt templates in .pi/prompts/ — slash commands like /survey-context, /plan-work
• pi package manifest in .pi/package.json — enables pi install with auto-discovery

Skills are loaded on-demand via progressive disclosure: only descriptions are always in context; the full SKILL.md loads when the agent reads it. Prompt templates expand in pi's editor with autocomplete.

🏗 The v2.0.0 Lifecycle

Every project follows the orchestrate-project 6-phase model (full SOP: docs/WORKFLOW-SOP-v2.md):

ONE TIME    seed-conventions  (CLAUDE.md, .claude/, .gemini/, agents/, skill sync)
              ↓
ONCE/PROJECT orchestrate-project
              │
              ├─ Ph1 DISCOVER   survey-context, research-first, elaborate-spec
              ├─ Ph2 ELABORATE  model-domain, grill-me, define-language, deepen-architecture
              ├─ Ph3 PLAN       scope-work, slice-tasks, plan-work → release-plan.yaml (BCP baseline)
              ├─ Ph4 BUILD      build-epic × N stories
              │
              │  Per story — 8-step build-epic cycle:
              │   1. survey-context   ← stamps story_start in state.yaml
              │   2. plan-work        ← [BCP N] tasks + verify: commands
              │   3. kickoff-branch   ← worktree + feature branch
              │   4. develop-tdd      ← RED → GREEN → REFACTOR
              │   5. verify-work      ← UAT gate
              │   6. audit-code       ← quality gate ≥ 94%
              │   7. commit-message   ← Conventional Commits + semver
              │   8. release-branch   ← land to main; writes story_end + cycle-times.yaml
              │
              ├─ Ph5 VERIFY     run-evals, verify-work (project-level)
              └─ Ph6 RELEASE    semantic-release → v1.0.0 MVP tag

Semver: projects start at 0.0.0-β; each feat: story → minor bump; developer declares MVP → 1.0.0.

BCP accounting: every task labeled [BCP N]; story total in state.yaml; BCP/hr logged to specs/metrics/cycle-times.yaml.

next_skill signaling: each critical-path skill writes handoff.next_skill to state.yaml. Call survey-context after any interruption to resume exactly where you left off.
