Show HN: CMV – strip up to 70% of Claude Code without losing any conversation

Hacker News - Thu, 02/19/2026 - 10:29pm

kept losing good conversations to /compact. you spend 40 minutes having claude map your codebase, it builds up real understanding, then context fills up and /compact crushes everything into a 3k token summary. "we discussed auth and decided on JWT." cool thanks.

dug into the actual session JSONL files and the breakdown is kind of absurd -- 60-70% is raw file contents from tool reads that claude already synthesized, another 15-20% is base64 thinking signatures. your actual conversation is like 10-15% of the window.

so i built cmv. it strips the junk and keeps every message verbatim. tool results over 500 chars become stubs, thinking sigs get removed, everything you said stays.

cmv trim --latest # trim and relaunch, 50-70% smaller

cmv snapshot "analysis" --latest # save a session state

cmv branch "analysis" --name "auth" # fork from it later

also has a TUI dashboard that shows the token breakdown per session so you can see what's eating your context before you do anything.

what it's not:

* not a token monitor (ccusage etc already do that)

* doesn't touch original sessions, everything creates copies

* local only, reads JSONL directly, no API calls

curious how others handle this. most people seem to just accept /compact but losing a deep architectural discussion to a bullet point summary felt wrong enough to build something.

Show HN: Codedocent – Code visualization for non-programmers

Hacker News - Thu, 02/19/2026 - 10:21pm

I'm a hardware engineer who reads schematics, not source code. I kept needing to understand codebases for projects I was managing but couldn't read the syntax. So I built a tool that turns any codebase into an interactive visual map with plain English explanations.

Point it at a folder, get nested colored blocks showing the structure (directories → files → classes → functions). Click to drill down. AI generates summaries written for humans, not programmers. Architecture mode shows a dependency graph so you can see how modules connect.

Built the whole thing in ~30 hours using a multi-node AI workflow: Claude for planning/decisions, Claude Code for implementation, five other models for adversarial security review (42 fixes across 6 rounds). I made every design decision; AI wrote every line of code.

Cloud AI (OpenAI/Groq) or local AI (Ollama) — your choice. pip install codedocent and run the setup wizard.

MIT licensed. Would love feedback from people who actually write code — does this help when onboarding onto unfamiliar codebases?

Show HN: Antenna, a command center for OpenClaw agents

Hacker News - Thu, 02/19/2026 - 10:12pm

Hi HN!

I’m building Antenna, a Mac app to manage an OpenClaw team in one place. If you run multiple agents, it gets messy fast: scattered chats, unclear command approvals, and poor visibility into what happened where. Antenna is my attempt to make that operationally sane.

Right now I’m focused on three things: seeing conversations across agents in one UI, approving commands safely, and keeping sessions manageable as context grows.

I’m currently testing better visibility into usage/context per session, smoother coding/review workflows, and lightweight controls that reduce complexity instead of adding more.

This is early and moving quickly. I’d really value feedback on: what would make this trustworthy enough for daily use, what’s missing for teams running multiple agents, and what would stop you from adopting it.

Show HN: 150M AI-Generated Q&A Pages Static

Hacker News - Thu, 02/19/2026 - 10:09pm

Over the past 6 months, our small team has been building Qeeebo — a large-scale question-and-answer knowledge archive designed to explore whether massive knowledge corpora can be published sustainably using fully static infrastructure.

This month, we are releasing:

• 150+ million structured questions • 24.5 million topics • 171 million topic-question relationships • 18+ million paginated topic pages • 100% pre-rendered static HTML • No origin servers — served entirely via CDN

Each question includes: – A full answer – A summary – Structured citation formats (APA, MLA, Chicago, IEEE, etc.) – Export formats (BibTeX, RIS, JSON-LD, YAML)

The entire system is generated in independent segments (~45k pages each), built across parallel machines running Hugo, then uploaded via automated multi-threaded pipelines with full failure tracking.

Why build this?

Large Q&A platforms historically struggled with sustainability — especially when operating on database-backed, dynamically rendered systems. We wanted to explore whether extreme-scale static generation could reduce infrastructure cost while increasing long-term durability.

This isn’t positioned as a replacement for Wikipedia or Stack Overflow. Instead, it’s an experiment in permanence and cost-efficient knowledge hosting at very large scale.

Happy to answer technical questions.
