Deliberate, security-first software construction that assumes a hostile user rather than an ideal one. Use this skill whenever code is being designed, written, extended, refactored, or reviewed before merge — features, endpoints, APIs, parsers, auth, file/DB/network/subprocess handling, schemas, architecture decisions — and whenever tests are being written, fixed, or reported. Threat model before file layout, trust boundaries before modules, fail closed by default, contract before diff, and…
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
# Secure by Construction A methodology for *writing* software, not for auditing it afterwards. It is the third member of a set: `abductive-engineering` supplies the A–D–I loop (abduction → deduction → induction) and the semiotic triad (sign → object → interpretant); `red-team-auditing` applies them adversarially to a finished system. This skill applies them *while the system is being built*, when defects are still cheap to not-introduce. It exists because a language model writing code has three strong and dangerous default habits: 1. **It codes for the ideal user.** The happy path is the path the training data rewarded. The hostile user, the confused user, the retry storm, the compromised dependency, and the maintainer two years from now are all absent from the prompt, so they are absent from the code. 2. **It codes fast.** Producing plausible code immediately is what it is rewarded for. But velocity drags errors behind it: a guess emitted with fluent syntax is indistinguishable, on the page, from knowledge. …

How to install
mdr add annatchijova/vigia-intent-analysis/secure-by-construction@sha256:4e5ed91d7b27dfbbThe line at the top of this page pins the label git:20260708.188dab9, 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.
