It supports multiple agents including Claude Code, Codex, and Cursor, and enables agents to search past sessions and observe other agents in real time. The tool is local-only, read-only, and MIT licensed.", "body_md": "Today we're open sourcing **Strata**, the session infrastructure that powers Stele.\n\n[https://github.com/Stele-Dev/strata](https://github.com/Stele-Dev/strata)\n\nCoding agents already leave surprisingly rich trails on your computer: prompts, responses, reasoning, tool calls, results, timing, token usage, cost, injected context, subagents, and more.\n\nThe problem is that every agent stores this differently.\n\nStrata turns those trajectories into one normalized CLI and TypeScript API.\n\nYou can use it to:\n\nIt currently supports Claude Code, Codex, Cursor, DeepSeek Harness, Gemini CLI, GitHub Copilot CLI, Kimi, OpenCode, and Pi.\n\nBut things get more interesting when **agents use Strata themselves**.\n\nRun `strata --skill`\n\nand an agent can learn the CLI.\n\nNow an agent can search previous sessions to find when and how something was built, inspect the trajectory behind a decision instead of rediscovering it, or watch another agent working in a different terminal in real time.\n\nAgent A can effectively observe Agent B.\n\nA message bus is also on the roadmap, opening the door for local agents to communicate directly through Strata.\n\nWe built Strata because we needed this infrastructure inside Stele. It powers Stele today, so while this is the first public release, the core has already been battle tested against real agent workloads.\n\nEverything stays on your machine.\n\n**Local-only. Read-only. No telemetry. MIT licensed.**\n\nYour coding agents already leave a trail. Strata makes it readable.", "url": "https://wpnews.pro/news/show-dev-strata-inspect-your-coding-agent-sessions", "canonical_source": "https://dev.to/stele/show-dev-strata-inspect-your-coding-agent-sessions-278b", "published_at": "2026-08-20 21:43:54+00:00", "updated_at": "2026-08-20 22:15:02.897881+00:00", "lang": "en", "topics": ["developer-tools", "ai-agents", "ai-infrastructure"], "entities": ["Stele", "Strata", "Claude Code", "Codex", "Cursor", "DeepSeek Harness", "Gemini CLI", "GitHub Copilot CLI"], "alternates": {"html": "https://wpnews.pro/news/show-dev-strata-inspect-your-coding-agent-sessions", "markdown": "https://wpnews.pro/news/show-dev-strata-inspect-your-coding-agent-sessions.md", "text": "https://wpnews.pro/news/show-dev-strata-inspect-your-coding-agent-sessions.txt", "jsonld": "https://wpnews.pro/news/show-dev-strata-inspect-your-coding-agent-sessions.jsonld"}}
