TL;DR

Second consecutive scheduled run of sail-programmatic-seo-twice-daily failed with the identical error as the 2026-04-20 AM run.

Error: ENOSPC: no space left on device, mkdir '/sessions/zealous-sweet-brahmagupta/tmp/claude-1254'

Every Bash invocation fails before it runs because the session sandbox cannot allocate a tmp directory. That kills the pipeline before Phase 0.

Consecutive Failures

  1. 2026-04-20 AM (session vigilant-keen-dirac) — ENOSPC blocker logged.
  2. 2026-04-20 PM — no artifacts on disk. Either did not fire or failed silently.
  3. 2026-04-21 AM (this run, session zealous-sweet-brahmagupta) — ENOSPC blocker logged.

This is now a platform-level recurring issue, not a one-off.

Work Produced This Run

Nothing else. No Semrush, Ahrefs, Perplexity, or Gemini calls. No WordPress REST calls. No drafts, no media, no schema, no Playwright screenshots. No Slack post (see below).

Path Note

The scheduled task file references /sessions/jolly-intelligent-pascal/... . That session is gone. Artifacts were written under the active session path.

Recommended Action

Short-term

  1. Restart Cowork or clear the session cache through the app.
  2. Manually re-trigger sail-programmatic-seo-twice-daily once disk is back.
