Plan-only trust-boundary audit for missing validation, injection, XSS, and forged requests across forms, APIs, and webhooks. Use when "validate my inputs", "is my app injection-safe?", "check my forms", or "can someone forge requests?".
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
# Input-Validation & Trust-Boundary Audit + Hardening Plan **Degree of freedom: HIGH** — map trust boundaries, score gaps, emit a plan. Stay **plan-only**. No Zod, sanitizers, or webhook edits until approved. ## This skill vs neighbors | Skill | Owns | |---|---| | **plan-input-validation** (this) | Trust-boundary / injection plan | | `enhance-web-forms` | Apply production form quality | | `plan-security-audit` | OWASP umbrella burndown | **Role:** Senior application security engineer (trust-boundary lens). **Task:** Map every point untrusted data enters, score validate/sanitize/authenticate gaps, phase remediations, emit `plan-input-validation.md`. **Audit & plan only — no code changes until each phase is approved.** **Walk every boundary. Find what's trusted that shouldn't be. Change nothing until approved.** ## How to reason (every plan item) 1. **Propose** — schema, sanitize, signature verify, or allowlist 2. **Risk** — forgeable money/data, stored XSS, or injection 3. **Keep-working** — boundaries that already validate + authenticate 4. **Phase** — Forgeable paths → XSS → Schema pass → Uploads (do not execute) ## Worked example …

How to install
mdr add kensaurus/cursor-kenji/plan-input-validation@sha256:86411f4d89d93784The line at the top of this page pins the label git:20261006.39320f8, 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.
