The agents wrote they were waiting for scheduled jobs, sub-agents, or conversations that either had wrong names, had already completed, or were archived. Each agent later self-corrected after daily reviews caught the errors. The root cause: agents wrote blocker names from memory or nearby log text without verifying existence via a command. The user now requires agents to run one verification command (e.g., `launchctl list | grep name`) before logging a blocker, attach the command output and timestamp, and treat only machine-verifiable blockers as true waiting states. Dates alone no longer count as blockers; instead, scheduled jobs wake agents on the due date.","keyPoints":["4 hallucinated blockers in 4 days across 3 Claude Code agents using Linear","Agents invented names of scheduled jobs, sub-agents, and archived conversations","New rule: verify blocker existence with one command before writing, log result and timestamp"],"whyItMatters":"Shows AI agents hallucinate in task management, not just chat, stalling workflows silently. A simple verification step catches errors at write time.","category":{"slug":"agents","name":"Agents & Tools","url":"https://digestai.news/category/agents"},"entities":{"companies":["Anthropic","Linear"],"models":["Claude Code"],"people":["Miku"]},"firstPublishedAt":"2026-10-24T07:03:00Z","updatedAt":"2026-10-24T07:03:00Z","sourceCount":1,"hasPrimarySource":false,"sources":[{"outlet":"note.com","title":"With Claude Code's multi-agent setup, AI was stuck waiting for a 'non-existent task'—hallucinations aren't just in conversation","url":"https://note.com/walkaround_jp/n/nea16c58ecf7a?hl=en","publishedAt":"2026-10-24T07:03:00Z","type":"press","primary":false,"lead":true}],"sourceNotes":null,"discussions":[],"thread":null,"cite":{"text":"Digest AI, \"Claude Code agents hallucinate non-existent blockers in multi-agent workflows\", 24 October 2026, https://digestai.news/story/claude-code-agents-hallucinate-non-existent-blockers-in-multi-agent-wo","publisher":"Digest AI","title":"Claude Code agents hallucinate non-existent blockers in multi-agent workflows","datePublished":"2026-10-24T07:03:00Z","url":"https://digestai.news/story/claude-code-agents-hallucinate-non-existent-blockers-in-multi-agent-wo"},"generatedBy":"Written by Digest AI's editorial model from the linked sources; the sources are the record.","license":"Headlines, digests and key points are written by Digest AI and may be quoted with a link to the story page.
