p4-kit

Claude Code status line with context-window and rate-limit threshold colors, plus the /statusline skill to inspect and customize it.

Authoring and auditing skills + CLAUDE.md files, organized as a verb x artifact matrix: md-authoring (/md-authoring) and md-audit (/md-audit) union domains over the md artifact, the cohesion-principles placement spine, and the canonical audit-framework (primitives, compositions, audit-kinds, viewer-kinds) that other plugins' audits and viewers ride on.

Experimental skills that may graduate into their own plugins. Currently hosts /claude-explorer (Omarchy-style HTML browser of ~/.claude/ + the current project, Python crawl + local HTTP serve + embedded SPA). Depends on plugins-kit:skills-kit for the shared audit framework.

Claude Code plugin marketplace (stable release channel)

OpenRouter API key management and account validation: shared library, CLI, and bootstrap-time credential check that other plugins/projects depend on for OpenRouter access

Centralized bootstrap engine for Claude Code plugins

Git + GitHub multi-agent code review (/git-code-review) plus gh CLI bootstrap (auth + optional org membership). Shares chunking + CLAUDE.md primitives with p4-kit via bootstrap_lib.code_review.

Cache usage reporting - per-request and session-level cache hit analysis from Claude Code transcripts

Christina's cross-domain skills: the task system (file-backed task/issue tracking -- folders as source of truth, embedded task_list references, plan.md task_items blocks enumerating each task's open items, 15 verbs; evolved from the hand-off skill in 0.8.0, which it replaces), a shared communication framework (task + verbose-updates), /plugin-ecosystem (interactive 16:9 HTML poster of marketplaces and plugins), and /html-pdf (convert an HTML file to PDF via headless Chromium and open it). Depends on plugins-kit:skills-kit for the shared audit framework and the skills_kit_lib shared library (schema validation + document walking).
