So I don’t think issue tracking is actually dead. It's very much alive and well. Bloated, human-era ticketing probably is dead though. Coding agents don't kill the need for structure; they actually demand more of it. The faster the agent, the faster context rots and work sprawls. Scaffolding isn't optional anymore; it's the only thing keeping the wheels on this thing, and why we created fp.dev

Claude sure likes “the gap”.

Shoutout to @daytonaio for organizing and @WorkOS for hosting a great night where builders gathered and of course giving us the opportunity to talk about how we're thinking about Autonomous Software Factories @fiberplane. Excellent conversations and new friends were made!

Check out our reference implementation called Otter, an opinionated monorepo template for autonomous agent workflows. Ships with: - @EffectTS_ conventions ast-grep enforcement - fp issue tracking with lifecycle hooks - Drift documentation anchoring - Agent skills pre-configured Open Source repo here: github.com/fiberplane/otter

This Tuesday we hosted our monthly @daytonaio AI Builders Meetup in San Francisco in partnership with @WorkOS & @coderhq. We had an incredible lineup of speakers covering topics from forkable sandboxes for long-running AI agents and self-driving codebases to scaling AI workflows in production, building reliable code review agents, generative UI patterns, and the infrastructure powering agentic software systems. Thanks to our speakers 🎤 @muhashmii × @daytonaio @matt_md5 × @WorkOS Jullian Pepito × @coderhq @HKrackDev × @coderabbitai @tyler_cpk × @CopilotKit @mies × @fiberplane Thank you to everyone who joined us. See you tonight at UC Berkeley for the AI Researchers Meetup!

Turns out codex doesn't care about getting a sandwich.

No Mac Minis were hurt during the creation of this process.
We've been running Claude Code autonomously on our codebase for months. The trick: enforcement that prevents errors from compounding across commits. - fp issue tracking with lifecycle hooks - @EffectTS_ traces - Drift-anchored QA scenarios - Commit discipline before context compaction How we built guardrails for agentic development fiberplane.com/blog/2026-04-…

drift is cool, check it out
Turns out the dark software factory runs on markdown. CLAUDE.md, specs, plans, REFACTOR-V2-BRAINSTORM.md. Agents read them as context and write more of them as output. When those docs drift from code, agents propagate the rot. Drift is the integrity layer.

My favorite new drift feature is anchoring markdown to markdown. So say you have a high-level docs/api-overview.md that tells developers "see the Authentication section for details." You don't want to duplicate the auth flow, but you do want to know when the auth docs change so you can update the overview.

The overview is flagged because the anchored section drifted; not because someone fixed a typo in auth.md's unrelated "Rate Limits" section. The anchor is section-precise. Drift is open source: github.com/fiberplane/drift

Big Things have Small Beginnings.
underrated: using @fiberplane to dissect big changes into smaller chunks, embrace the exponentials, come back and check the work

We're sooo back
issue tracking riseth from the ashes

Issues and brainstorms as markdown. Local first, sync optional. Our bet is simple: in an agent-native workflow, the issue stops being paperwork and actually becomes the control plane. Plan the work. Bound the task. Keep the memory. Check out fp.dev

We've been building with @Claude Code at @fiberplane since early days. Biggest takeaway: agents don't get better because you prompt them better. They get better when the codebase is explicit enough to constrain them. @EffectTS_ for typed errors dependencies. Team favorite ast-grep to enforce patterns at commit time. Our own Drift to catch stale docs. We wrote up our entire setup, learnings and shares our rules here: fiberplane.com/blog/2026-04-…
