ECC vs ponytail
Cross-harness 'operating system' for coding agents — 268 skills, 66 agents, hooks, rules, memory persistence, instinct-based continuous learning and AgentShield security scanning. MIT. — versus — A skill that makes your agent code like the laziest senior dev: YAGNI enforced — ~54% less code, ~20% cheaper, ~27% faster on measured Claude Code sessions. Works with 20 agents.
Opposite philosophies for shaping a coding agent: ECC installs an entire operating layer — hooks, gates, orchestrators; ponytail installs exactly one opinion. Maximalist vs minimalist, and the choice says more about your team than the tools.

ECC — the 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.
ponytail — the curator's take
One opinion, installed: the best code is the code you never wrote. Where every other add-on gives your agent MORE — more context, more tools, more process — ponytail gives it restraint, and the benchmarking is unusually honest: ~54% mean code reduction across 12 real tasks (94% is the over-building ceiling, not the average), with the safety-guard regression of a naive 'write one-liners' prompt explicitly tested and avoided. Works across 20 agents. NOT for codebases where verbosity is the convention (enterprise Java won't thank you), and watch the trajectory: 88k stars, a waitlist banner and ponytail.dev — the skill is free today, the product is coming.
