ExHarness

One-command installer for an opinionated Elixir/Phoenix static-analysis suite, plus a mix harness.init whole-codebase audit (dialyzer + reach).

Installation

mix igniter.install ex_harness
mix harness.install
mix deps.get

Skip individual tools with --skip:

mix harness.install --skip makeup,makeup_elixir

Whole-codebase audit

mix harness.init               # dialyzer + reach, output to .harness/
mix harness.init --skip dialyzer
mix harness.init --quick       # reuse existing PLT

The audit writes .harness/audit-<timestamp>.md (and a latest.md copy) summarising dialyzer findings, reach taints, and dead code.

What gets installed

Library	Role
`credo`	Style / complexity / design lints
`dialyxir`	Success-typing analysis
`ex_dna`	Duplicate code detection
`ex_slop`	File naming / docstring lints
`boundary`	Compile-time module boundary enforcement
`reach`	Program Dependence Graph (taint / dead code)
`makeup` + `makeup_elixir`	Syntax highlighting for reach reports

mix harness.install also:

adds :boundary to the compilers: list,
writes a :dialyzer config (priv/plts/),
appends to (or creates) the precommit mix alias,
creates priv/plts/.gitkeep and updates .gitignore,
drops a default .credo.exs if none exists.

After installing

mix deps.get
mix dialyzer --plt (one-time PLT build, 30–60s)
Add use Boundary to each top-level context — see the boundary docs.
mix harness.init for the first audit.
