bigdra50/skills

A collection of agent skills maintained by @bigdra50, distributed via APM.

Each directory is a standalone skill following the agentskills.io open standard.

Install

Install an individual skill (global / user scope):

apm install -g bigdra50/skills/<category>/<skill-name>

Or declare it in apm.yml for a reproducible setup:

dependencies:
  apm:
    - bigdra50/skills/<category>/<skill-name>

then run apm install.

These follow the open Agent Skills format, so any compatible agent (Claude Code, Codex, opencode, Gemini CLI, Cursor, ...) can use them without APM:

npx skills add bigdra50/skills --skill <skill-name>

Skills — Global

Language / domain agnostic. Install globally via apm install -g.

For Unity / C# Development

Unity and C# skills are project-scoped — install them per-project, not globally.

Setup

Add to your Unity project's apm.yml:

name: my-unity-project
version: 1.0.0
targets:
  - claude
dependencies:
  apm:

Unity / C# Review System

Uses unilyze for static analysis and unity-cli for project metadata.

Start with review-triage, then run the observation skills it recommends. Use review-weekly to orchestrate all review skills together.

Skill	Description
review-triage	Day 0 scorecard — CodeHealth, assembly structure, test posture, top 3 risks.
review-metrics	Per-type metric deep-dive with unilyze evidence packs.
review-architecture	Assembly (asmdef) structure — dependency direction, DfMS, cyclic deps.
review-hotspot	Git churn x complexity refactoring priorities.
review-duplication	Code clone detection and classification.
review-performance	Unity hot-path smells, GC allocation, Burst/DOTS readiness.
review-safety	Async patterns, exception handling, resource disposal.
review-testing	Test posture — EditMode/PlayMode coverage, CI, test design quality.
review-unity-specific	Unity-specific gotchas no static analyzer catches.
review-weekly	Weekly orchestrator — runs all observation skills, dispatches perspectives, diffs KPIs.

Perspective sub-skills (dispatched in parallel by review-weekly): unity/perspectives/{unity-architect, performance-engineer, xr-specialist, test-engineer}.

Unity Development Skills

Skill	Description
asmdef-lint	Assembly Definition structure validation — naming, dependency direction, test assemblies.
