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.

Google opened its Deep Research and Deep Research Max agents to developers via the Gemini API, running on Gemini 3.1 Pro. These are the same autonomous research agents that power the consumer Gemini experience — now available as API primitives you can embed in your own apps, dashboards, or agentic workflows. Deep Research Max is benchmarked at 93.3% on DeepSearchQA, a record for autonomous research. The April 2026 API launch adds capabilities beyond the consumer product: MCP server support for connecting to private data and professional streams (FactSet, S&P Global, and PitchBook integrations are already live), native chart and infographic generation inline with research output, and the ability to mix sources simultaneously — web search, uploaded PDFs/CSVs/video/audio, and URL context. Code Execution and File Search also run alongside web grounding in a single call. For developers building research-heavy apps — competitive intelligence, financial analysis, legal research, scientific literature review — this is a meaningful unlock. Rather than chaining together search, retrieval, synthesis, and visualization layers yourself, the Deep Research API handles the full multi-hop research loop. Pricing and rate limits at enterprise scale remain the key question.
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.”
“The MCP integration is the real story — connecting Deep Research to our internal data warehouse with a single server definition and getting research-grade synthesis in return is exactly what enterprise AI apps need. This replaces three separate pipeline stages for us.”
“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.”
“93.3% on DeepSearchQA sounds great until you hit domain-specific queries where benchmark performance rarely holds. With Google controlling the search layer, there are legitimate questions about source diversity and SEO-optimized results contaminating research quality.”
“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.”
“When every developer app embeds a research agent that simultaneously queries the live web and private data, the gap between Bloomberg Terminal-quality research and a startup's internal tool effectively collapses.”
“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.”
“Native chart generation inside research output is the killer feature — I can hand a client a report with visualizations baked in, not just text summaries. That changes the entire deliverable format for research-heavy creative work.”
