End-to-end agentic feature development AND bug-fix workflow. Use when the user gives a feature goal or wish item (e.g. "make calorie detection automatic", "add X to the app", "I want Y behavior") OR reports a bug to be fixed (e.g. "the banner can't be cleared", "this crashes when...", "this shows the wrong language") and expects AI to handle analysis → scope/diagnosis → behavior spec (frontend+backend) → happy/unhappy/edge paths → industry practice → test cases → verifiable steps → code →…
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
# Agentic Dev E2E Turn a one-line feature wish into verified, reported code with at most two human touch points. The human provides the wish and (at risk gates) value judgments; the agent does the cognitive labor and proves its own work with environment evidence, never self-declaration. Core law: **the spec is the ceiling of the whole chain.** A wrong spec executed perfectly is still wrong, and errors correlate downstream — a later phase cannot detect an earlier phase's misunderstanding. That is why gates sit where they sit. ## Hard rules (never violated, any repo) 1. **Artifact per phase.** Each phase writes a fixed-format file to `.agent/features/<slug>/` before the next phase starts. Later phases read the files, not conversation memory. Conversation memory is not durable state. 2. **Evidence, not declarations.** Verify-report items cite raw evidence: test-run summaries, build logs, screenshots, console output paths. A bare "passed" without evidence is a failed check. Claim "no gate failure observed", never "verified correct". 3. **Verifier ≠ generator.** Verification runs in a fresh subagent context …

How to install
mdr add labs21-dev/agents-stack/agentic-dev-e2e@sha256:64148c6603f168dcThe line at the top of this page pins the label git:20260912.9d47cf0, 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.
