GitHub - swenyai/sweny: AI-powered engineering workflows ...

AI workflows as code. Describe what you want, get a reliable DAG.

Quickstart

npx create-sweny            # pick a workflow → auto-detects providers → done
sweny workflow run .sweny/workflows/pr-review.yml

Or if you already have @sweny-ai/core installed:

sweny new

Already have a .sweny.yml? sweny new adds additional workflows non-destructively.

Build a workflow from scratch — pick "Describe your own" in the sweny new picker, or:

sweny workflow create "review PRs for security issues and code quality"
sweny workflow run .sweny/workflows/pr-review.yml

# Visualize any workflow as a Mermaid diagram — drop it into a PR or README
sweny workflow diagram .sweny/workflows/pr-review.yml -o pr-review.mmd

Keep the CLI current:

sweny upgrade          # pulls the latest @sweny-ai/core via your package manager
sweny upgrade --check  # dry-run: just report the available version

Browse marketplace.sweny.ai for ready-to-run workflows.

What it does

Describe a task in plain English. SWEny builds a DAG of focused AI agents — each node gets its own MCP tool set scoped by the skills it declares, structured output, and conditional routing. Every tool call is tracked. (The underlying Claude Code agent process keeps its built-in tools available so nodes stay agentic inside their box; see ARCHITECTURE.md for the exact capability contract.)

$ sweny workflow create "audit our repo for security issues, \
    scan dependencies, and create Linear tickets for anything critical"

  GitHub Security Audit

  o Scan Recent Commits for Exposed Secrets
  |
  +---> o Review Open PRs for Security Changes
  +---> o Scan Dependencies for Vulnerabilities
       |
  o Compile Security Posture Report
  |
  o Create Linear Tickets for Critical Findings

  Save to .sweny/workflows/github_security_audit.yml? [Y/n/refine]

Use it anywhere

Surface	What it does
CLI	Build, run, and publish workflows from your terminal
GitHub Action	Run any workflow on CI — plus dedicated triage and e2e actions
Studio	Visual DAG editor and live execution monitor
Claude Code Plugin	Slash commands, MCP tools, and an isolated workflow agent
Marketplace	Browse, fork, and share community workflows

Custom skills

Extend any workflow with your own skills. Scaffold one in a single command:

sweny skill new code-standards -d "Team TypeScript conventions"
sweny skill list

Or write the file by hand at .sweny/skills/code-standards/SKILL.md:

.sweny/skills/code-standards/SKILL.md

---
name: code-standards
description: Team coding conventions for TypeScript
---

When reviewing TypeScript code:
- Use camelCase for variables and functions
- Every public function needs at least one test
- Mock at boundaries (HTTP, DB), not internal functions

Then reference it in any workflow node:

nodes:
  review:
    name: Code Review
    instruction: Review the pull request.
    skills: [code-standards, github]

Skills are cross-tool compatible — the same SKILL.md works in Claude Code, Codex, and Gemini CLI. Write once, use everywhere. Learn more.

Built-in skills

Set the credential, the skill is ready. No configuration.

Skill	What it does
github	Search code, read files, create issues, open PRs
linear	Create, search, and update issues
sentry	Query errors, issues, and stack traces
datadog	Query logs, metrics, and monitors
betterstack	Query incidents, monitors, and logs
slack	Send messages via webhook or bot API
notification	Discord, Teams, email, generic webhooks

GitHub Actions

# Run any workflow on CI
- uses: swenyai/sweny@v5
  with:
    workflow: .sweny/workflows/security-audit.yml
    claude-oauth-token: ${{ secrets.CLAUDE_CODE_OAUTH_TOKEN }}
  env:
    LINEAR_API_KEY: ${{ secrets.LINEAR_API_KEY }}

Focused actions for common use cases:

Action	Purpose
`swenyai/sweny@v5`	Run any workflow YAML
`swenyai/triage@v1`	SRE triage — observability + issue tracker
`swenyai/e2e@v1`	Agentic E2E browser tests

Cloud reporting (optional)

SWEny runs locally or in CI with zero phone-home behavior by default. To enable the cloud dashboard at cloud.sweny.ai:

Sign up and link your repo — the GitHub App handles this in one click.
Copy the CI reporting token from your project page (starts with sweny_pk_).
Add it as a GitHub Actions secret named SWENY_CLOUD_TOKEN.
Expose it to the Action:

- uses: swenyai/sweny@v5
  with:
    workflow: .sweny/workflows/security-audit.yml
    claude-oauth-token: ${{ secrets.CLAUDE_CODE_OAUTH_TOKEN }}
  env:
    SWENY_CLOUD_TOKEN: ${{ secrets.SWENY_CLOUD_TOKEN }}

Without SWENY_CLOUD_TOKEN, the Action performs no network calls to sweny.ai. No anonymous telemetry, no pings, nothing.

See PRIVACY.md for the full data policy.

Publish to the marketplace

Share your workflows and skills with the community:

sweny publish   # interactive CLI — publish a workflow or skill
