No previous Codex task thread was found for this repository.

Error message

No previous Codex task thread was found for this repository.

What it means

In executeTaskRun, when request.resumeLast is true the code calls resolveLatestTrackedTaskThread to find a thread to continue. If that returns null (no resumable tracked task, no thread on disk, and no session-scoped thread), there is nothing to resume and the run aborts. This is distinct from the no-prompt error which follows.

Solutions

1. Run a task without --resume-last first to create an initial thread.
2. Verify the workspace state directory contains task jobs with a threadId.
3. If session filtering is the cause, ensure SESSION_ID_ENV matches the session that created the prior task.

Example fix

// before
codex-companion.mjs task --resume-last
// after
codex-companion.mjs task "initial prompt"   # creates a thread, then --resume-last works

const thread = await resolveLatestTrackedTaskThread(workspaceRoot);
if (!thread) throw new Error('no prior thread');

/** @param {{id: string}|null} t @returns {t is {id: string}} */
function hasThread(t) { return t != null && typeof t.id === 'string'; }

When it happens

Trigger: First-ever task run in a repo with --resume-last, or after all prior task jobs were cancelled/failed without a threadId, or when the session id filter excludes all existing jobs and no global thread exists.

Common situations: New workspace, cleared state directory, or running under a new Claude session id that has no associated task history.
