Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# SDLC Studio

> An open Agent Skill (agentskills.io format) that runs the full software development
> lifecycle - PRD, epics, stories with executable acceptance criteria, implementation,
> testing, verification, reconciliation - with deterministic gates that hold the agent to
> what the files actually say. Installs into Claude Code, Codex, Gemini CLI, opencode and
> GitHub Copilot; invoked as /sdlc-studio [type] [action] or model-invoked from plain
> language.

How to install

The exact contents, by fingerprint
mdr add darrenbenson/sdlc-studio/llms.txt@sha256:7618d5a97919da84

The line at the top of this page pins the label git:20260708.60d981f, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
