Run the full product development lifecycle loop, from discovery through launch and measurement, with proceed/pivot/kill gates at every phase.

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

# Product Development Lifecycle

Orchestrates the full PDLC loop by invoking phase skills in sequence.
Each phase consumes the previous phase's artifact and ends in a gate (`make-decision`) with verdict `proceed` / `pivot` / `kill`.
Pass an optional phase name to enter the loop at a specific stage.

PDLC wraps SDLC: it decides *whether* and *what* to build, hands the *how* off to SDLC at `define-acceptance`, then finishes the loop with launch and measurement.

## When to Use `/pdlc` vs Individual Skills

- Use **`/pdlc`** (with an optional phase name) when you want the orchestrator to run multiple phases, manage gates and backtracking, and keep run state.
  The PDLC phase skills are **internal sub-skills** bundled under this `pdlc` skill at `skills/pdlc/skills/<name>/SKILL.md`.
  They are not individually discovered as slash commands, so only `/pdlc` is directly invocable; the orchestrator loads each phase by reading its file (see *Load Each Phase Sub-Skill* below).

How to install

The exact contents, by fingerprint
mdr add tomzx/agents/pdlc@sha256:456d54d2b4c57469

The line at the top of this page pins the label git:20261007.b35fc4b, 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.
