SD-11 scanner-mediated injection — neutralize untrusted skill bytes before any model; additive-only scoring. Use when touching L2, MCP, prompts, envelopes, or scoring merge.
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
# SD-11 If the scanner forwards skill text to a model, the scanner is the injection surface. 1. Strip bidi / zero-width / tag chars; record removals as findings. 2. NFKC + UTS #39 skeleton; homoglyphs are findings, not silent folds. 3. Remaining text goes in a fenced untrusted envelope. No raw skill in the model prompt. 4. Host returns schema-constrained JSON only. 5. Merge: L2 may add or raise. L2 may not delete or downgrade L1. 6. If neutralize fails: do not call the model; reduce L2 coverage. No vendor LLM SDK on the default CLI path. Product L2 is MCP `mode=host`.

How to install
mdr add kalarislabs/skill-doctor/neutralize-sd11@sha256:de3d4f694bdf14e3The line at the top of this page pins the label git:20260910.eee8645, 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.
