# openplanr 0.6.0

Published 2026-03-29.

[Release on GitHub](https://github.com/openplanr/OpenPlanr/releases/tag/v0.6.0)

## Added

**Error context helper** — truncates large build logs for clearer failure output

## Fixed

**Agent hangs on large prompts** — implementation prompt is delivered via temp file + stdin pipe instead of a giant CLI argument (avoids OS argv limits and interactive “wait forever” behavior)

**Stream backpressure** — prompt delivery uses `createReadStream` → `stdin` pipe instead of buffered `stdin.write`

**Codex sandbox** — `--full-auto` and `--json` so Codex can write files and emit structured events (matches Claude-style progress output)

**Claude stderr** — retryable 400/429/5xx errors detected while still showing output in real time

## Changed

**Agent stdout/stderr** — `stdio: inherit` for live agent output where applicable

**Safety** — system prompt guidance to reduce destructive cross-project commands

## Developer Experience

**Linting and formatting** — ESLint and Prettier replaced with [Biome](https://biomejs.dev/) (`biome check` / `biome format`)
