information-hiding skillA
information-hiding is agent-read markdown (skill) from codybrom/clairvoyance: Checks for information leakage across module boundaries, including temporal decomposition and false encapsulation. Use when modules change together, implementation details leak across boundaries, or structure follows execution order rather than knowledge ownership. Not for merge/split decisions (use module-boundaries) or interfaces over-specialized for one caller (use general-vs-special)..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# Information Hiding Review Lens When invoked with $ARGUMENTS, focus the analysis on the specified file or module. Read the target code first, then apply the checks below. Evaluate whether modules encapsulate design decisions effectively. ## When to Apply - Reviewing module boundaries or class decomposition decisions - When multiple modules change together for single-decision changes - When private fields have matching getters and setters - When modules are organized around execution steps (read/process/write) - When a format, protocol, or representation appears in multiple places ## Core Principles ### Knowledge Ownership Test For every design decision in the code (data format, algorithm choice, protocol, storage representation): 1. Which module owns this decision? 2. Is that ownership exclusive, and no other module knows this? 3. If this decision changes, does only one module need editing? If #3 is "no," there is information leakage. ### Two Kinds of Leakage #### Interface Leakage The decision appears in parameters, return types, or exceptions. Bad, but at least visible and discoverable. #### Back-Door Leakage …

How to install
mdr add codybrom/clairvoyance/information-hiding@git:20260722.fcfda01mdr add codybrom/clairvoyance/information-hiding@sha256:0139353faf315057Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
