Show HN: Open Chronicle – Local Screen Memory for Claude Code and Codex CLI I built an open source version of OpenAI Chronicle.

Some design decisions I made:

1. Local first: OCR uses Apple Vision, summarization supports local AI providers via Vercel AI SDK. Nothing leaves your computer. 2. Multiple Provider: exposes MCP so any coding agents can use it. 3. Swift menubar app: efficient, low-footprint 4. Blacklist apps: password managers, messaging apps (Slack, WhatsApp, Messenger), mail clients are on default blocklist.

Current Limitations: 1. Mac only. Mac-first is a feature. 2. Small local models with weak structured-output support will fail on generateObject. 3. Retrieval is LIKE-query keyword search. FTS and optional embeddings are on the list.

Curious what you think the right balance between exclusionlist allowlists. Happy to answer anything.

Show HN: Gemini Plugin for Claude Code

Show HN: Gemini Plugin for Claude Code I built a plugin that lets Claude Code delegate work to Gemini CLI.<p>I started this after finding myself reaching for Gemini more often on long context repo work. I have been especially liking Gemini’s codebaseinvestigator for long context.<p>This is inspired by openai&#x2F;codex-plugin-cc.<p>Code Review, adversarial review. Under the hood its Gemini CLI over ACP<p>Would love feedback from people using Claude Code, Gemini CLI, or ACP. I am especially curious whether this feels useful outside my own workflow.<p>Its a great combo with Opus 4.7 + Gemini 3.1 workflows

Show HN: gcx – The Official Grafana Cloud CLI

Show HN: gcx – The Official Grafana Cloud CLI Hi HN,<p>We’re excited to share gcx, a new CLI we’ve been building for Grafana Cloud.<p>With the rise of agentic coding tools like Claude Code and Codex we&#x27;re building faster than ever, but these agents are often blind to what’s actually happening in production.<p>gcx brings the full power of Grafana Cloud observability to your terminal. Query production. Investigate alerts. Let the Assistant root-cause issues. Ship fixes with observability built in. Without leaving your editor. gcx also comes packaged with a skills bundle that allow agents to see and act on your production telemetry. You can ask an agent to root-cause a latency spike, and it can actually fetch the telemetry, analyze the spans, and suggest a fix—all while having the full context of your codebase.<p>Do check it out and give us feedback!<p>Github link: <a href="https:&#x2F;&#x2F;github.com&#x2F;grafana&#x2F;gcx" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;grafana&#x2F;gcx</a>
