Awesome Codex Skills is a curated repository of 50+ modular skills for extending OpenAI's Codex CLI and API with real-world integrations. Built by Composio — the company behind one of the leading tool-use infrastructure platforms — each skill is a SKILL.md file with metadata and step-by-step instructions that Codex can automatically trigger based on task descriptions. The skill library spans five categories: Development & Code Tools (codebase migrations, CI/CD fixes, MCP builders, code reviews), Productivity & Collaboration (issue triage, meeting intelligence, Notion integration), Communication & Writing (email drafting, changelog generation, resume tailoring), Data & Analysis (spreadsheet formulas, competitive research, log analysis), and Meta & Utilities (design tools, skill templates). The key integration hook is Composio's 1000+ app connector library, meaning skills can perform real actions — not just generate text. This is the Codex counterpart to the growing Claude skills ecosystem, and it arrives at exactly the right moment as Codex 3.0 gains adoption. If you're building agent workflows around OpenAI's toolchain, this is the fastest way to get production-grade integrations running without building API adapters from scratch.

Modo
AI IDE that writes specs before code — not just a Cursor clone

Modo is an open-source AI IDE built on the Void editor (a VS Code fork) that flips the script on how AI coding tools work. Instead of jumping straight to code generation, Modo forces a spec-first workflow: describe what you want, and the agent converts your prompt into structured requirements docs, design docs, and task breakdowns stored in a persistent `.modo/specs/` directory before writing a single line of code. The approach draws from the "vibe coding is bad actually" school of thought. Modo's steering files and agent hooks let developers set coding conventions, stack preferences, and project constraints that persist across sessions. Autopilot mode chains spec generation through implementation, while parallel chat lets you run multiple agent conversations simultaneously against the same codebase. Built by a solo developer and posted to Hacker News as a Show HN, Modo positions itself against Cursor, Windsurf, and Kiro. The bet: slowing down agents with structured planning up front produces fewer hallucinated architectures and rewrites. It's early — rough edges abound — but the spec-driven philosophy is increasingly mainstream as larger teams adopt AI coding tools.
Reviewer scorecard
“The CI/CD fix skill and MCP builder skill alone justify installing this. Composio's 1000-app integration layer behind the scenes means these aren't just text templates — they're wired to real APIs. This is the missing middleware for Codex.”
“Spec-driven development is exactly what enterprise AI coding needs. I've watched too many Cursor sessions generate 500 lines of code that ignored the actual architecture. Modo's persistence layer and steering files are the missing piece — this deserves a serious look.”
“This is fundamentally a Composio marketing vehicle. The real integrations require Composio's platform, not just the skills file. Check whether the tool you want actually works before getting excited about the README.”
“It's a solo project on a VS Code fork with 23 Hacker News points. Void itself is already a niche alternative — building a workflow tool on top of it means you're two layers of maintenance away from stability. The spec idea is sound but wait for something with a team behind it.”
“Skill libraries are becoming the new package registries for the agentic era. Composio publishing 50+ production integrations as open-source SKILL.md files is how the broader agent ecosystem standardizes around common patterns.”
“Documentation-first coding is how agents will scale. When you have 10 agents working on one codebase, human-readable specs become the shared source of truth — not the code itself. Modo is ahead of the curve on this even if it's rough today.”
“The email drafting, changelog generation, and resume tailoring skills are immediately useful for content creators and technical writers. Having these as composable units rather than custom prompts is a real workflow improvement.”
“As a non-developer using AI to build tools, having the AI generate a structured plan I can actually read and edit before it touches code is a game changer. Most AI IDEs treat me as a passenger. Modo treats me as a co-pilot.”
