Curator's take

The kitchen-sink option, and the most popular one by a wide margin: one install gives Claude Code, Codex, Cursor, OpenCode and friends a full operating layer — session-memory hooks, learned instincts, quality gates, orch-* orchestrator commands, worktree lifecycle, security scanning — plus three genuinely good guides on token optimization, memory and agentic security. When NOT: it's maximalist. Hundreds of skills and global hooks add context weight, and the README's own top warning is about broken stacked installs — start with the minimal/no-hooks profile and never mix the plugin with the manual installer. If you only want one capability, take the surgical tool instead: claude-reflect for learning-from-corrections, pro-workflow for session memory, asm or skillkit for skill management. Watch the upsell surface (Pro app, sponsors) — the OSS core is MIT and complete.

pro-workflow

One SQLite store under every Claude Code session: corrections become FTS5-searchable rules that auto-load, research grows persistent wikis, and 37 hook scripts add quality gates.

Why it fitsSame job — a persistent operating layer under coding-agent sessions with hooks, learned rules and quality gates. pro-workflow is one SQLite store focused on Claude Code; ECC is the maximalist cross-harness system spanning 7+ harnesses with skills, agents and security tooling.

claude-reflect

Claude Code plugin that learns from your corrections — hooks capture them in-session, /reflect syncs approved learnings to CLAUDE.md/AGENTS.md, /reflect-skills mines history into reusable commands.

Why it fitsBoth close the learning loop from your corrections: claude-reflect is a focused Claude Code plugin syncing approved learnings to CLAUDE.md; ECC's instinct system does the same continuous-learning job with confidence scoring inside a much larger harness framework.

apm

Microsoft's dependency manager for agent context — declare skills, prompts, plugins and MCP servers in apm.yml; one install reproduces the setup across 8 clients with lockfile pinning and org policy.

Why it fitsBoth ship reproducible agent-context setups across many clients. apm is a lean dependency manager (declare skills/prompts/MCP in apm.yml, lockfile-pinned installs); ECC ships the content itself — a batteries-included catalog of skills, agents, hooks and rules.
