Source-backed software architecture intelligence for codebase audits, ownership topology, runtime topology, architecture conformance and drift checks, structure metrics, module boundaries, dependency flow, ADRs, architecture fitness functions, and incremental refactoring strategy.
Use when intended architecture must be compared with implementation: dependency policies, ADRs, ownership rules, drift, erosion, recovered models, and conformance classifications.
Use when structural code choices need durable rationale: ADRs, tradeoffs, consequences, reversibility, ownership, review triggers, and validation plans.
Use when architecture choices need executable guardrails: dependency rules, cycle checks, boundary tests, ownership review gates, ADR compliance, runtime/resilience checks, and CI fitness functions.
Use whenever code work has structural consequences: project architecture, module boundaries, dependency direction, runtime topology, ownership, ADRs, fitness functions, or architecture refactoring.
Use when architecture crosses ownership or review boundaries: CODEOWNERS/OWNERS, module coverage, cross-owned dependencies, socio-technical coordination, and governance paths.

Ready-to-install skills and plugins that make coding agents better at real development work.
Plug'n Skills is a library of plugin packs for Codex, Claude Code, and other coding agents. Each pack gives an agent a focused workflow: what to inspect, which commands to run, what to verify, and when to use a deterministic helper instead of improvising from a prompt.
Use it when you want an agent that can handle more than generic code edits:
The repository ships 13 installable plugin packs and more than 150 focused
agent skills. Every pack is plain repository content: manifests, SKILL.md
files, references, validators, and helper scripts. You can inspect it, validate
it from a fresh clone, install only the packs you need, and keep generated local
marketplace or cache state out of the repo.
For most users, the simplest path is to paste this prompt into the coding agent you already use:
Install Plug'n Skills from https://github.com/Xopoko/plug-n-skills on this
computer. Follow the repository instructions for the coding agent you are
running in, validate the source tree first, use a dry run before writing global
plugin state, install only the plugin packs I request unless I ask for all of
them, and report exactly what was changed.
git clone https://github.com/Xopoko/plug-n-skills.git
cd plug-n-skills
python3 scripts/validate-repository.py
Preview the Codex install plan before writing global state:
python3 scripts/install-codex-plugins.py --dry-run
Install or refresh every plugin from this checkout:
python3 scripts/install-codex-plugins.py
python3 scripts/install-codex-plugins.py --check-only
Install only selected plugin packs:
python3 scripts/install-codex-plugins.py --plugin capability-workbench
python3 scripts/install-codex-plugins.py \
--plugin kotlin-multiplatform \
--plugin spec-driven-development
The installer validates the repository, generates a local Codex marketplace
file at .agents/plugins/marketplace.json, points Codex's local marketplace
at this checkout, enables the selected plugins, and materializes cache entries
under ~/.codex/plugins/cache/local/....
.agents/ and Codex cache directories are local runtime state. They are not
part of the published source tree.
Add this repository as a Claude Code marketplace, then install the plugin pack you need:
/plugin marketplace add Xopoko/plug-n-skills
/plugin install capability-workbench@xopoko-plug-n-skills
/reload-plugins
For a local checkout, use the checkout path instead of the GitHub shorthand:
/plugin marketplace add /path/to/plug-n-skills
Claude Code reads the root .claude-plugin/marketplace.json and each plugin's
.claude-plugin/plugin.json.
