Use when the user wants any spec-driven development action — exploring before speccing, deriving specs from code or translating specs from another system, proposing a change, applying or implementing, verifying, syncing delta specs, or archiving. Triggers: 'spec this out', 'create a change', 'apply tasks', 'verify implementation', 'sync specs', 'archive change', or any mention of 'specs' or 'sdd'.
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
# SDD — Spec Driven Development Route user intent to the correct `sdd-*` child skill. Classify first, then confirm with the user before routing. ## Writing Style Write every SDD artifact in the voice of a professional technical writer. Prefer ASD-STE100 Simplified Technical English: short sentences, one instruction per sentence, active voice, and one term per concept. Keep identifiers, commands, paths, and RFC 2119 keywords exact. This applies to all `sdd-*` skills. ## Trigger Tests Should trigger: - "Spec this feature out" - "I want to create a change proposal" - "Apply the tasks in my change" - "Verify that I implemented everything correctly" - "Sync the delta specs into main" - "Archive the auth-refactor change" Should not trigger: - "Help me brainstorm" - "Write a commit message" - "Debug this Python error" - "Review my PR" ## Invocation Notice - Tell the user when this skill is running: `sdd`. Skip the notice when the user asked for the skill by name or slash command; spelling and spacing need not match. A phrase from this skill's own trigger list is not a name — naming the work is not naming the skill. ## What is a SPECS_ROOT? …

How to install
mdr add ahgraber/skills/sdd@sha256:8ce1866264c7ea02The line at the top of this page pins the label git:20261017.d9ba006, 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.
