FLOWSTACK UI

Swifty LLC

NaCl

ITSalt

NaCl (reading as Natrium Chloride) is an open-source full-SDLC framework, and its core innovation is how it solves the hardest problem in agentic development: storing and retrieving project knowledge. Instead of markdown specs that agents must re-read every session, all project knowledge — requirements, architecture decisions, entities, rules, and their relationships — lives in a Neo4j knowledge graph as first-class queryable objects. The measured effect: planning a single use case takes ~550 tokens (one targeted Cypher query) instead of ~150,000 tokens (reading a ~70-file markdown spec, because the agent doesn't know in advance where the relevant facts live) — a 99.6% reduction in context per use case, repeated in every planning session. Around the graph we've built the full tooling for agentic development and testing: 57 skills covering BA → SA → TDD development → review → QA → release, quality gates before production, and an autonomous goal orchestrator (/nacl-goal). The framework answers "how is this built and why" for any part of the system, regardless of project scale or iteration count. Benchmarked on a real production project (EV charging station management): a classical team was estimated at 5,831 person-hours; running fully on NaCl the same scope takes 1,480 person-hours — 4x fewer person-hours and 60% lower cost.

Engineering Project OS

Pavel Bochkov Rastopchin

Developer tooling for Codex to resume repository work across sessions and persist plans, findings, evidence and checkpoints. Use this when work must survive context compaction or reviewed failure lessons need to move into another repository you own. Project OS inspects, bootstraps, validates, repairs and upgrades visible repository records with previews before writes. ChatGPT is a companion for explanation, supplied project files and portable knowledge bundles. Do not use it for ordinary one-session coding or as an automatic global knowledge service.

GH Review Loop

Oren Ashkenazy

Clears AI reviewer feedback on a GitHub PR without leaving your coding agent. Waits for the configured reviewer (Codex, CodeRabbit, Copilot, or any compatible bot), reads real review-thread state via GraphQL so resolved, outdated, and already-answered threads are skipped, then fixes what is actionable in severity order. Findings are clustered by kind, so a pattern flagged at two sites gets swept across the PR's changed files in one cycle instead of dripping back over three reviews. Every fix is gated on your repository's own tests and linters before it is pushed, and re-review requests are hard-capped (default 3) so the loop cannot spam the PR. Optional per-finding triage flags false positives before you spend a cycle on them, and each run leaves an audit trail plus local stats.

Apprentice

Abhishek Samar Singh

Apprentice spots code that sends the same shape of request to a frontier model over and over, in a loop, a cron job or an endpoint. It shows you how to capture verified examples from calls you already make, then test whether an optimized prompt or a small fine-tuned model holds quality for less.
