- loop-engineeringhuytieu/COG-second-brainShared loop-engineering reference for COG skills - the agent loop, deterministic verifiers, termination conditions, in-loop context management, and named patterns. Invoke when designing or debugging a skill that iterates (search-verify-retry, scan-until-dry, fetch-retry-gate).EngineeringNo warnings★ 1.3K↓ —
- editorial-illustrationshuytieu/COG-second-brainSelf-evolving second brain with 35 AI skills, 10 agents, and people CRM.

- gamehashgraph-online/awesome-codex-pluginsMake or change a rules-plus-view multiplayer web game inside a Homie studio — the server runs the rules, each browser predicts its own movement and renders the game, strangers meet in public rooms, bots fill empty seats, rounds end and restart — prove it with two browsers finishing a round, and give it an epic landing page (a full-bleed hero from its own footage or art, the pitch, Play, phone / computer / TV, live rooms, how to play, credits). Use when someone in a Homie studio (a folder with studio.json) asks for a new game, a change to a game, a game whose own AI decides (opponents picking tactics, an NPC's reaction, a director's call, a turn's move), or a better page for a game ("make my game's landing page epic").DesignNo warnings★ 1.5K↓ —

- documenthashgraph-online/awesome-codex-pluginsRecord a decision, document existing code, or file a supplied research material. Modes: document decision (ADR, RFC, or rule), document code (spec, doc, guide, or scenario for existing behavior), document research (only when a finished report or one external material is already in hand). Use for 'we decided', 'record this decision', 'document why we chose X', 'make it our standard', 'draft an RFC', 'should we switch to Y' proposals, 'resolve the RFC', 'we accepted the proposal', 'document the auth module', 'capture how the payment system works', reference material, how-to instructions, or a user flow with examples over an existing spec. Name the type inside the subject to skip the type question. Planning a feature or an intended user journey → /archcore:plan.

- planning-with-filesOthmanAdi/planning-with-filesPersistent file-based planning for multi-step AI-agent work. Keeps task_plan.md, findings.md, and progress.md on disk; lifecycle hooks inject selected project planning context. Automatic recovery reads project planning files only. Explicit session-catchup.py --metadata reads same-project local agent session records and emits aggregate counts only; --replay may emit bounded nonce-framed excerpts. Optional gated mode can request continuation only when the host supports it and never runs commands declared in Markdown. The skill has no network upload path. Use for research or work needing 5+ tool calls.PlanningNo warnings★ 27.9K↓ —Also in 1 other repo

From the author
Define a data contract between a producer and consumers of a dataset/event/API. Use when asked to write a data contract, define a schema agreement, set data SLAs, or stop a producer from silently breaking downstream consumers. Produces a contract — schema with types & constraints, semantics, quality SLAs (freshness/completeness/validity), ownership, versioning & breaking-change policy, and a change process.
