Systematic agentic software development upgraded with TypeSafe Jev System One typed decisions.

Why

Autonomous coding agents equipped with standard development methodologies still fail in predictable, expensive ways:

Hallucinated Packages: Agents invent fake npm packages or dead crates during implementation planning.
Arbitrary Architecture Guessing: Agents flip coins on stack decisions and database choices during brainstorming without calibrated confidence.
Unchecked Destructive Execution: Agents run destructive shell commands or push unverified git commits containing credentials or bugs.
Premature Turn Completion: Agents declare tasks "done" based on optimistic assumptions rather than verified evidence.

jev-superpowers upgrades the battle-tested obra/superpowers methodology with TypeSafe AI Jev System One (jev-1.13.0). Every architectural fork, dependency selection, shell command, and completion check is gated by sub-second deterministic mathematical judgments.

Empirical Benchmarks

Design targets measured on the maintainer setup; reproduce with scripts/test.sh plus your own Jev usage logs before quoting them:

Metric	Standard Agent Superpowers	`jev-superpowers` Upgrade
Package Hallucination Rate	~14% unvetted libraries	near 0% when every dependency passes `jev-scout`
Architectural Gate Latency	3.5s – 12s (generative LLM)	~70ms – 120ms typical Jev round trip
Per-Decision Verification Cost	~$0.015 – $0.030	~$0.00001 at $0.042/Mtok input
Pre-Commit Diff Screening	Manual / none	Sub-second automated gate (`git-jev`)
Local Test Suite Run	N/A	offline suite, see `scripts/test.sh`

Core Superpowers

Skill	Phase	Standard Superpower	`jev-superpowers` Upgrade
`jev-brainstorming`	Ideation	`brainstorming`	`jev-axi pick` trade-off convergence with calibrated confidence ($>0.80$)
`jev-writing-plans`	Planning	`writing-plans`	`jev-scout` zero-hallucination crate & repository verification
`jev-executing-plans`	Execution	`executing-plans`	`jev-guard` command safety + `git-jev` pre-commit reflex gate
`jev-systematic-debugging`	Triage	`systematic-debugging`	`jev-axi triage` error analysis + Jev `Score` hypothesis ranking
`jev-verification`	Completion	`verification-before-completion`	`limpet` turn stop-hook + `supercov quality` anti-pattern scoring

The Toolchain Suite

jev-superpowers orchestrates dedicated single-purpose tools powered by TypeSafe Jev System One:

Tool	Role	Install Command	Repository / Package
`git-jev`	Sub-second Git pre-commit & pre-push reflex gate	Precompiled binary / `cargo install`	`AkashPriyadarshii/jev-git`
`jev-scout`	Zero-hallucination crate & repo scout	`cargo install jev-scout`	`AkashPriyadarshii/jev-scout`
`jev-axi`	Fast System One diff review, error triage & choice pick	`npm install -g jev-axi`	`shiftynick/jev-axi`
`jev-guard`	Destructive shell command filter (<80ms)	Installed with `jev-axi` / standalone	`leepokai/jev-guard`
`supercov`	Jev code quality & anti-pattern oracle	`npm install -g supercov`	`supercorp-ai/supercov`
`limpet`	Agent stop-hook completion policy gate	Precompiled binary / `cargo install`	`KSym04/limpet`
`jev-seo`	Zero-cost SEO/GEO audit radar & citation scoring	`cargo install jev-seo`	`AkashPriyadarshii/jev-seo`

For detailed recipes and terminal execution traces of each gate, see the Full Usage & Recipes Guide (docs/USAGE.md).

Quickstart

1. One-Line Installation

Linux / macOS:

curl -fsSL https://raw.githubusercontent.com/AkashPriyadarshii/jev-superpowers/master/install.sh | bash

Windows (PowerShell):

irm https://raw.githubusercontent.com/AkashPriyadarshii/jev-superpowers/master/install.ps1 | iex

2. Configure Your ₹0 Jev API Key

export TYPESAFE_API_KEY="your_api_key"
# Windows PowerShell: $env:TYPESAFE_API_KEY = "your_api_key"

Non-Goals

Not a chat agent: Does not provide a conversational chatbot; strictly provides structured agent skills.
No cloud execution: All checks run locally via native CLIs on your laptop.
No multi-agent swarm bloat: Zero heavy orchestration frameworks or Docker containers.
