Proactive secure-coding coach scoped to the file or topic you are working on — surfaces relevant SAST rule IDs, CWE patterns, language-specific PASS/FAIL code snippets. Use when about to write auth, crypto, SQL, deserialization, file-handling, or template code; coaching juniors; pair-programming a security-sensitive change.
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
# Vulnetix Secure Code Write Skill ## Use when - About to write authentication, crypto, SQL, deserialization, file-handling, or template code. - Coaching a junior on a new security-sensitive feature. - Pair-programming a security-sensitive change with a reviewer who wants to surface rules upfront. - Reviewing a PR and want the rule digest the author should have seen. - Cross-referencing the SAST rules that would fail BEFORE writing the code that triggers them. ## Don't use for - Actually scanning code — use `sast-scan`. - Generic security advice — this skill is rule-grounded, not narrative. - Educating non-developer audiences — the rule digest is engineer-targeted. ## Conventions Follows `skills/_lib/contract.md`. In short: use the `vulnetix_*` MCP tools when the agent has them and the CLI otherwise — both shape their own output, so there is no jq step any more. Independent calls go out as concurrent Bash tool calls in one message. One trailing suggestion, not a playbook. See the contract for surface selection, output style and memory writes. …

How to install
mdr add vulnetix/pix-ai-coding-assistant/secure-code-write@sha256:f75c4dff630e008dThe line at the top of this page pins the label git:20260904.974b690, 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.
