boundaries from oliver-kriska/claude-elixir-phoenix is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add oliver-kriska/claude-elixir-phoenix/boundaries@git:20261002.9767a82Pins git:20261002.9767a82 in mdr.lock. Pin the fingerprint instead.

Analyze Phoenix context boundaries and module coupling via mix xref. Use when checking cross-context calls, validating dependencies, before splitting modules, or reviewing architecture.
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
# Phoenix Context Boundary Validation Analyze module dependencies to ensure clean context separation and proper architectural boundaries. ## Usage ``` /phx:boundaries # Check for violations /phx:boundaries --assess # Score context health (0-100) /phx:boundaries --fix # Suggest fixes for violations ``` ## `--assess` Mode: Context Health Score Evaluate overall boundary health with a quantified score. ### Metrics Calculated | Metric | Healthy Range | Red Flag | Weight | |--------|---------------|----------|--------| | Modules per context | 3-15 | >20 or <2 | 20% | | Public API surface | 5-30 funcs | >40 funcs | 15% | | Fan-out (contexts called) | 1-4 | >6 | 20% | | Fan-in (called by contexts) | 1-6 | >10 | 15% | | Circular dependencies | 0 | >0 | 15% | | Boundary violations | 0 | >0 | 15% | ### Commands for Assessment Use Glob to count `.ex` files per context directory under `lib/my_app/*/`. Use Grep to count public function definitions per context file under `lib/my_app/*.ex`. Run `mix xref graph --format stats` for dependency analysis. Run `mix xref graph --format cycles --label compile` for compile-time circular dependencies. ### Output Format …

How to install
mdr add oliver-kriska/claude-elixir-phoenix/boundaries@sha256:3077571e3b78bd9eThe line at the top of this page pins the label git:20261002.9767a82, 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.
