+# `@sentiolabs/pi-code-quality`
+
+`@sentiolabs/pi-code-quality` provides Pi-native code-quality skills and prompts for slop review and size review.
+
+## Included resources
+
+- Skill: `/skill:slop-review`
+- Prompt alias: `/code-quality-slop [scope]`
+- Skill: `/skill:size-review`
+- Prompt alias: `/code-quality-size [scope]`
+- References: Go, Python, Rust, and Svelte/TypeScript slop-review guidance; default size-review exclusions
+
+## Slop review workflow
+
+`slop-review` reviews code through four lenses: AI authorship signals, idiom fluency, code quality, and architecture/solution fit. It is the workflow for deciding whether the implementation itself looks suspect.
+
+## Size review workflow
+
+`size-review` reviews how a change is packaged for human review: raw versus post-exclusion size, stacked branch shape, viable seams, split effort, and concrete stack plans.
+
+## Usage
+
+```text
+/code-quality-slop
+/code-quality-slop src/
+/code-quality-slop #123
+/skill:slop-review
+
+/code-quality-size
+/code-quality-size #123
+/code-quality-size feature/my-branch
+/skill:size-review
+```
+
+## Portability
+
+The package does not require Arc or `pi-subagents`. It uses parallel agent tools when available and falls back to sequential lens passes otherwise.
+
+## Local development
+
+```bash
+npm test --workspace @sentiolabs/pi-code-quality
+npm run pack:dry-run --workspace @sentiolabs/pi-code-quality
+pi -e ./packages/pi-code-quality

+# Pi Code Quality Package
+
+> Monorepo location: this package lives at `packages/pi-code-quality` in the `pi-nexus` workspace. From the monorepo root, test it with `npm test --workspace @sentiolabs/pi-code-quality` and load it locally with `pi -e ./packages/pi-code-quality`.
+
+Pi skills and prompts for AI slop review, PR/branch size review, and code reviewability analysis.
+
+This package ports the Claude Code `code-quality` plugin's `slop-review` and `size-review` workflows to Pi.
+
+## What is included
+
+- `/skill:slop-review` — 4-lens slop review for AI authorship signals, idiom drift, code quality issues, and architecture/solution-fit problems.
+- `/code-quality-slop [scope]` — prompt alias for reviewing current changes, files, directories, PRs, or broad codebase scopes.
+- `/skill:size-review` — PR/branch size review that decides whether a change should be split, stacked, cleaned up, or shipped as-is.
+- `/code-quality-size [scope]` — prompt alias for reviewing the current branch, a PR, or a named branch for reviewability and stack seams.
+- Slop-review language references for Go, Python, Rust, and Svelte/TypeScript.
+- Size-review default exclusions for generated files, lockfiles, vendored output, and common machine-generated artifacts.
+
+## Workflow distinction
+
+`slop-review` evaluates what the code does and whether the implementation quality or solution fit is suspect. `size-review` evaluates how the change is packaged for human review: raw vs post-exclusion size, stacked branch shape, viable seams, split effort, and concrete stack plans.
+
+## Portable execution
+
+The `slop-review` skill is portable. When the current Pi session exposes a parallel agent tool, the review can run Step 0 first and then run the applicable Phase 1 lenses in parallel. When no parallel tool is available, the same lenses run sequentially in the current agent context with separated findings.
+
+Parallelism is opportunistic; the review methodology, calibration, scoring, and output format are the contract.
