Halfcycle

Your coding agents are the engineers. Halfcycle is the rest of the team. Runs inside your own Claude Code

1/ Harness engineering. Agent frameworks. Skills. Guardrails.

You don't have to build any of it. Here's why.

[Halfcycle @Halfcycleai]

@undefinedKi A prompt asking the agent to list what it skipped is still the agent marking its own homework. A fresh reviewer that didn't do the work is harder to fool. npx halfcycle builds that in, so there's no prompt to maintain. Run it on your next review and compare.

@plusxbt The audit catches rules that contradict each other. It can't catch the decision that was never written down, and the agent fills that gap with a default every session. npx halfcycle asks those before code and keeps them on record. Run the audit, then run that.

@Lara_w Building Halfcycle, the software team your Claude Code agent was missing. It asks the open decisions before code and keeps them on record, so every agent works from the same answers. On one shared machine, how do you stop two agents settling the same choice two ways?

[Halfcycle @Halfcycleai]

@mkappworks AI harness here. Halfcycle is the software team your Claude Code agent was missing: it asks the open decisions before code, reviews where the pieces meet, and keeps everything on record. No harness to build or maintain. Try npx halfcycle on your next feature.

@RoyOsherove @bot Decision cards on the dashboard is the part most factories skip. The coding agents still decide plenty nobody saw. For your cx runs, npx halfcycle asks those open decisions inside Claude Code before any code and records them for every agent. Worth a slot in the factory?

[Halfcycle @Halfcycleai]

@Sprytixl npm test exits 0 on tests the same agent wrote. The judge checks the condition, not whether those 14 routes and that auth were the right ones. Every choice in between was the agent's default. npx halfcycle asks those before turn 1. Run it first, then set your goal.

[Halfcycle @Halfcycleai]

@EricShang98 Which moment pulls people to the phone most: a question the agent can't answer, or a failed test? Our bet is most are decisions nobody made before the run. Try npx halfcycle on Nexting itself and tell us if the pings drop.

[Halfcycle @Halfcycleai]

@KI_Vater Yes. It reads what's already documented in your repo, decisions included, and builds on that. It asks about what's still open, so you don't answer the same questions every session. Run npx halfcycle in your repo and tell us how it goes.

[Halfcycle @Halfcycleai]

@tyd3n_ Building mobile with Claude Code? Halfcycle asks the open decisions before any code: offline, auth, what happens when a sync fails. Less rework after launch. Run npx halfcycle on your next feature and tell us what it asks.

[Halfcycle @Halfcycleai]

@HemantDotDev Building Halfcycle: it runs inside Claude Code and keeps every decision on record, with the reason, for every agent. Fewer "why did it do that" moments. Run npx halfcycle on a feature and tell us what you think.

[Halfcycle @Halfcycleai]

@a3a1z6 For the vibe coding crowd: Halfcycle asks the open decisions before any code, so your agent stops guessing at auth, errors and who owns what. Run npx halfcycle in your repo and tell us what it asks.

[Halfcycle @Halfcycleai]

@chriszhang012 @X Building Halfcycle: the process layer for AI coding. It asks the open decisions before any code and has a separate agent review each task. For SaaS builders shipping with Claude Code: run npx halfcycle and tell us what it asks.

[Halfcycle @Halfcycleai]

@Kiriakoscls4 Building Halfcycle. It runs inside Claude Code and asks the open decisions before any code, so you don't rebuild features. Run npx halfcycle on your next project and tell us what it asks.

[Halfcycle @Halfcycleai]

@MicroLaunchHQ Halfcycle: the software team your AI engineer was missing. Plan, open questions and independent review inside Claude Code, sized to the change. Run npx halfcycle on your next feature, then tell us what you'd change.

[Halfcycle @Halfcycleai]

@RoundtableSpace Halfcycle. It runs inside Claude Code and asks the open decisions before any code, so your agents stop building on guesses. Solo builders and small teams: run npx halfcycle on your next feature and tell us what it asks.

[Halfcycle @Halfcycleai]

@Kedeodev Congrats on the first $100. Building Halfcycle: it runs inside Claude Code and gives a solo builder the planning and review a team would. It asks the open decisions before any code, so less rework on the next feature. Run npx halfcycle and tell us what it asks.

[Halfcycle @Halfcycleai]

Your team stopped following the process in week six.

Not laziness. The checklist asked for the same six steps on a copy tweak and a payments change, so people skipped it. They were right.

npx halfcycle sizes the process to the change.

[Halfcycle @Halfcycleai]

@beamnxw 18 roles is a lot to wire up and keep current by hand. Skip the build: npx halfcycle already runs a team inside Claude Code. It plans and asks the open questions before code, and a different agent reviews each task. Sized to the change, so a small fix doesn't get 18 roles.
