frodi-karlsson/onesie 3

forge

claude

Codebase-aware specification engine. Runs a grounded interview that captures implicit facts as A-AUTO-NNN entries, emits typed Global Invariants / State Transitions / Contracts tables, runs an adversarial spec review at R3.5, and writes a foundry-ready spec with version frontmatter — locked, classified, and verifiable. Brownfield runs produce a flow delta against the existing system; greenfield runs produce an end-state spec; cosmetic runs skip flow mapping. Forge plans. Foundry builds.

ac-lsp

claude

Language servers for Claude Code that stay in step with the disk and stay quiet: Dart, PHP, TypeScript and JavaScript, Python, Go, Swift and HTML behind one proxy that holds retracted diagnostics, drops ghosts of deleted worktrees, filters hints and environment noise, and stops idle servers.

LSP

godot-kit

claude

Verdicts an agent loop can trust: skills that make Claude actually run, test and verify a Godot 4 project instead of trusting exit codes.

localixai/localix-marketplace 3

Agent Rally Point — repo-local coordination surface for parallel coding agents. Claude Code has a plugin integration; Codex has Rally skills and needs project hook configuration; Cursor uses project hook configuration; Gemini and other hosts use the CLI loop. Records claims, checks write boundaries, routes handoffs, and exposes room state via the rally CLI. Skills: agent-rally-point (per-session loop), rally-workflows (fan-out + dynamic-workflows protocol), mini-loop (per-task quality gate). Hooks auto-fire only in supported, configured projects on SessionStart + PreToolUse to surface room awareness and deconflict before edits; advisory by default (the edit goes through), with opt-in strict and fail-closed switches that block. Backend: rally CLI (cargo install --path crates/rally-cli).

trowel

claude

Lean spec-to-code build workflow: code-driven preflight and planning, builders that reuse what the project already has, each slice spec-checked as it lands, the project's real end-to-end check run in code, and at most two batched fix rounds. A separate plugin; forge and foundry are unchanged.
