Ferretlog is a zero-dependency pure Python CLI that treats your Claude Code session logs like a git repository. It parses the raw JSONL logs in `~/.claude/projects/` and gives you git-style history browsing, diff between runs, per-tool-call breakdowns, and cost/token stats — entirely locally, with no network calls and no configuration required. If you've been using Claude Code heavily, you've likely experienced the frustration of losing track of what changed across sessions, what tools were called how many times, and how much each session actually cost across sub-agent calls. Ferretlog makes that history explorable and comparable the same way `git log` makes code history explorable. This is an indie solo project from Eitan Lebras, submitted as a Show HN. It's genuinely useful as a power-user tool for anyone doing serious Claude Code work, especially those managing multi-session agent pipelines where debugging "what did the agent do last time?" is a real pain. The zero-dependency, local-only design means there's no trust surface and no setup friction.

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.

If you run Claude Code daily, you need this immediately. Being able to diff two sessions like git commits and see exactly which tools fired and what they cost is something that should have existed from day one. Zero-dependency Python means it just works.

80/100 · ship

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.

Skeptic

This is a niche tool for a niche user (heavy Claude Code power users) and the session log format Anthropic uses is undocumented and could change at any update. Tying workflows to internal log parsing is fragile infrastructure — treat it as a convenience, not a dependency.

45/100 · skip

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.

Futurist

Agent observability tooling built by the community, not the vendor, is how this ecosystem will mature. Ferretlog is primitive but it points at a real gap: we need git-style versioning and auditability for agent sessions, not just for code.

80/100 · ship

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.

Terminal-only, Claude Code-specific, no visuals — this tool exists entirely outside my workflow. The underlying insight (session replay and cost tracking) is useful, but it needs a UI before it reaches anyone outside the developer community.

80/100 · ship

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.
