Tech spec generation and review. Use when: designing features, writing specs, spec review. Not for: requirements analysis (use req-analyze), implementation (use feature-dev), architecture advice (use codex-architect). Output: numbered tech spec document.
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
# Tech Spec Skill ## Trigger - Keywords: tech spec, technical specification, spec review, review spec, feature design ## When NOT to Use - Creating request documents (use /create-request) - Code implementation (use feature-dev) - Architecture consulting (use /codex-architect) ## Commands | Command | Purpose | When | | --------------- | -------------------- | ----------------------- | | `/tech-spec` | Create or update tech spec | Auto-detects create/update from filesystem state | | `/deep-analyze` | Deepen spec + roadmap | After initial concept | | `/review-spec` | Review tech spec | Spec confirmation | ## Context-Aware Mode (Upsert) When invoked without a full requirement description, the skill auto-detects the target feature using the cascade in `references/native-feature-resolution.md` — this skill's own reference, and deliberately command-free. This skill grants `Bash(git:*)` and not `Bash(node:*)`, so the resolver script is not a command it may run — and it does not link the shared reference that teaches it, because a file of unrunnable …

mdr add sd0xdev/sd0x-harness/tech-spec@sha256:0f70763b33826acdThe line at the top of this page pins the label git:20260905.1599675, 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.
