Cross-skill index of observed failure modes. Each skill carries its own Failure mode blocks under the Principle they violated; this file is the flat scan across all of them, plus process-level pitfalls that don't have a skill home. Read at project kickoff and during code review.
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
# Factory pitfalls The skills are now structured Principle → Why → Recipe → **Failure mode**, with each anti-pattern co-located with the principle it violates. This file is a flat scan across those failure modes plus process-level pitfalls that don't fit any one skill. ## How to use this skill - **At project kickoff.** Read this index; ensure the starting setup avoids the top-tier pitfalls (no test coverage, no DECISIONS.md, hardcoded allowlist). - **In code review.** Scan recent diffs for matches; link the relevant skill section in the PR comment. - **After incidents.** Add the failure mode to the skill where its principle lives (not here); if it doesn't fit any skill, add a process pitfall below. ## Cross-skill failure index Each entry: one line, pointing at the skill section that owns it. ### Stack / architecture - **Mixed tRPC + server actions** — `factory-api.md §API style — pick one` - **Custom auth adapter when an official one exists** — `factory-auth.md §Better Auth — plugin composition` - **Triple-fallback auth surface (Clerk → token → header)** — `factory-auth.md §The wrapper interface` …

How to install
mdr add nonlinear-xyz/factory-kit/factory-pitfalls@sha256:4b1fa4748c365090The line at the top of this page pins the label git:20261029.d37b2cc, 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.
