-
cross-code-organizer
Cross-Code Organizer (formerly Claude Code Organizer): cross-harness config dashboard for Claude Code, Codex CLI, MCP servers, skills, memories, agents, sessions, security scanning, context budget, and backups.
The scanner is extracted from Claude Code Organizer, so it knows exactly where to look. Not just ~/.claude/. It finds project-scoped .claude/ directories too, and decodes those hashed paths under ~/.claude/projects/.
-
modularity

Project mention: The new Power Platform Pro-Code Era: Code Apps vs Power Pages SPA | dev.to | 2026-06-03🔵 Power Pages SPA has native server-side JavaScript endpoints hosted at /_api/serverlogics/. These run on the server, never expose secrets to the client, can aggregate data across multiple Dataverse tables, and can call external REST APIs or Azure Functions with credentials stored safely. The /add-server-logic skill in the power-platform-skills AI plugin can generate these endpoints from a natural-language description — see the AI-assisted development section below.

superpowers-optimized
Optimized fork of Superpowers — Retains full original features while adding automatic 3-tier workflow routing, integrated safety guards (OWASP-aligned), red-team adversarial testing with auto-fix pipeline, a built-in memory stack, and much more. Delivers faster, more reliable, hallucination-resistant coding sessions.
Project mention: Forked the Superpowers plugin: Fixed its amnesia, bloat and lack of safety rails | news.ycombinator.com | 2026-03-20 -
Project mention: Alive – Five Markdown files that give Claude Code a persistent memory | news.ycombinator.com | 2026-03-17
- insights.md — stuff that doesn't change
Save at session end, load at session start. 12 hooks enforce the structure, log entries are immutable, deletions are blocked, context re-injects when the window fills up. The model can't talk its way out of the guardrails.
Also works with OpenClaw (separate plugin, same files - in alpha). Your Mac Mini captures all day, Claude Code does focused work, both read the same project context.

sugar
Persistent memory for AI coding agents. Local-first, cross-session context, global knowledge, and optional autonomous task execution. (by roboticforce)
Project mention: Ask HN: What are tools you have made for yourself since the advent of AI | news.ycombinator.com | 2026-06-081. Built an agent memory tool since all agents and clis are dumb and don't remember anything. Instead of prepping 300 project files and Md files I just say:
Check sugar memory for the latest thing we were working on.
2. The second thing is when making changes across a large codebase agents are also dumb at figuring this out and also grep 300 things, using tons of tokens. Instead I say
Check RemembrallMCP to analyze the impact of the change.
