No after-chat-turn tags found.

Error message

No after-chat-turn tags found.

What it means

This CommandExecutionError is thrown by the task-fs files command when no `turn` argument was supplied and the repo contains no tags starting with `after-chat-turn-`. The command sorts tags by committerdate and takes the newest matching ref; with zero matches it cannot proceed.

Solutions

  1. Pass an explicit --turn <id> to pick a before-chat-turn tag instead of relying on the latest-after default
  2. Check `git -C <repo> tag -l` to see what tags exist and use one via --turn
  3. Re-run the Trae task to completion so an after-chat-turn snapshot is captured
  4. If tag naming changed in a newer version, align the CLI and snapshot producer versions

Example fix

// before
let ref = raw.split('\n').find((t) => t.startsWith('after-chat-turn-'));
if (!ref) throw new CommandExecutionError('No after-chat-turn tags found.', '');
// after
let ref = raw.split('\n').find((t) => t.startsWith('after-chat-turn-'))
       || raw.split('\n').find((t) => t.startsWith('before-chat-turn-')); // fallback
if (!ref) throw new CommandExecutionError('No chat-turn tags found.', '');
Defensive patterns

Strategy: fallback

Validate before calling

const tags = gitInRepo(repo, ['for-each-ref', '--format=%(refname:short)', 'refs/tags']).split('\n').filter(Boolean);
if (!tags.some((t) => t.startsWith('after-chat-turn-'))) {
    console.warn('No after-chat-turn tags; specify --turn to use a before-* tag.');
}

Try / catch

try {
    const rows = await runTaskFsFiles({ 'task-id': tid });
} catch (e) {
    if (/No after-chat-turn tags found/.test(e.message)) {
        // fall back to an explicit before-chat-turn tag
        return runTaskFsFiles({ 'task-id': tid, turn: latestBeforeTurnId(repo) });
    }
    throw e;
}

Prevention

When it happens

Trigger: Calling the task-fs files command without --turn on a snapshot repo that has only before-chat-turn-* tags (a turn started but never completed), or a repo with no tags at all, or tags created with a different naming convention.

Common situations: A turn failed mid-way so only the before snapshot exists; querying a task that never completed a chat turn; a version change in snapshot tag naming (snapshot tool no longer uses the after-chat-turn- prefix).
