reply-drafter agent stuck regenerating the same apology: loop break

Not specified by the original author.

TL;DR

A drafter stuck regenerating the same apology is failing its own quality check repeatedly without changing strategy: same input, same output, same rejection. Break the loop with a stall detector (three similar drafts triggers escalation), force strategy variation on retry (different structure, not just rewording), and hand the ticket to a human after the cap. Regeneration without variation is the definition of the loop.

The query

reply-drafter agent stuck regenerating the same apology: loop break

Use this when

• The drafter produces near-identical drafts repeatedly
• Drafts never pass the quality check
• Agent time is wasted reviewing the same draft
• You are operating an AI reply drafter

Not for

• Building the drafting pipeline
• Tuning reply tone or style
• Writing apology templates
• Reviewer training

Steps

1. Detect the stall: similarity across attempts

Compare each new draft against previous attempts for the same ticket. Past a similarity threshold on the third attempt, declare a stall. Do not let the drafter burn ten attempts hoping for variation.

Expected output: stall declared after three similar drafts.

2. Force strategy variation on retry

A retry must change approach, not wording: lead with the action instead of the apology, switch from explanation to bullet-point resolution, shorten drastically. Encode distinct strategies the drafter must cycle through.

Expected output: retries visibly differ in structure, not just phrasing.

3. Check whether the quality gate is unsatisfiable

Sometimes the loop is the gate's fault: the requirements contradict (be brief but cover everything, be warm but use the template). Review the gate criteria against the ticket. An impossible gate loops forever.

Expected output: gate criteria confirmed satisfiable, or fixed.

4. Escalate to a human after the cap

Three strategies tried, still failing: the ticket goes to a human with the draft history attached. The human sees what was tried and why it failed, which is genuinely useful context.

Expected output: stalled tickets reach humans with full draft history.

5. Log stalls as training signal

Every stall is a labeled example: ticket plus the failing drafts plus the human's eventual reply. Collect them. They are the highest-value training data for the drafter because they mark exactly where it fails.

Expected output: a stall log feeding drafter improvement.

Template: the checklist

Drafter apology loop:
[ ] Stall detection: three similar drafts triggers escalation
[ ] Retries change strategy, not just wording
[ ] Quality gate checked for contradictory requirements
[ ] Human escalation after the cap, with draft history
[ ] Stalls logged as training data

Variant phrasings

ai drafter same reply repeatedly

Steps 1 and 2. Detect similarity, force variation.

reply generator stuck in loop

Steps 1 and 4. Cap attempts, escalate.

drafter never passes quality check

Step 3. The gate may be unsatisfiable.

Why it happens

The drafter optimizes against a quality gate, and when the gate rejects a draft the drafter's best move is a small perturbation of the same draft. Without enforced strategy variation, hill-climbing on a rejected draft converges to the same apology with different words. The loop is rational local optimization with no global escape.

Edge cases

• The ticket genuinely needs an apology plus specifics the drafter lacks: missing data stalls look like loops. Check data availability first.
• Overly strict tone gates: "sound human" plus "use the template" can contradict. Loosen one.
• Multi-issue tickets: the drafter apologizes for issue one while the gate wants issue two addressed. Decompose before drafting.
• Human reviewers rubber-stamping: if reviewers approve anything, the gate is theater. The loop then never triggers because nothing gets rejected.

TL;DR

Stop the loop by checking the mail drafts and sent folders for an existing draft built from this demo summary before creating another, cap draft creation at one per summary, and require a human send decision so drafts cannot regenerate on a schedule by themselves. Start with the agent run history showing repeated follow-up drafts, the demo summary it sourced, and the send or draft log in the mail tool, work on one affected call, record, or run first, and prove the fix there before running the full set. Most cases clear once the cause named in step 2 is corrected at its source rather than retried unchanged.

agent loop detected resending the same follow-up email draft from a demo summary

Use this when

• You see this exact message or symptom: agent loop detected resending the same follow-up email draft from a demo summary
• One run, record, call, or object is affected and you can name it
• A retry without changing anything reproduces the same result

Not for this skill when

• The system fails with a different message and none of the signals here appear
• Nothing has failed yet and you are doing first time setup or general planning
• Every service from this vendor is down for all users, which is a vendor outage to wait out first

Steps

1. Reproduce the failure once using the agent run history showing repeated follow-up drafts, the demo summary it sourced, and the send or draft log in the mail tool, and record the time, the workspace or account, and the one item it names. Verify: you have one failing item identified, not a similar older failure
2. Inspect how many drafts exist for the same summary, what triggered each creation, and whether any completion check ran first. Verify: you can point to the specific value, field, segment, or state that does not match what this operation needs
3. Apply the fix at that source: stop the loop by checking the mail drafts and sent folders for an existing draft built from this demo summary before creating another, cap draft creation at one per summary, and require a human send decision so drafts cannot regenerate on a schedule by themselves. Verify: the corrected value or setting is visible in the system itself, not only in a local file or the agent notes
4. Re-run the original operation on the single affected item first. Verify: that one item completes with no trace of the failure described above, and one draft exists for the demo summary and a rerun creates no additional copy
5. Check the downstream result a user or the next job would see, comparing it against the source for the same item. Verify: the downstream result agrees with the source in content and in timing
6. Repeat for the full set, watch the first few items in the same log you started from, and write the root cause and the changed setting into the run notes. Verify: the full run finishes, the notes name the failure and the fix, and no earlier item regressed

Variant phrasings

agent loop detected resending the same follow-up email draft from a demo summary

The subject-first phrasing of the same failure. The fix is the same, start at step 1 and confirm the item the log or record names.

Tool-first phrasing of this failure

The phrasing searchers use once they know which system raised it. It is the same underlying problem, not a separate bug.

Why does this keep happening after a retry

The repeat-occurrence phrasing. A retry without the step 2 and step 3 checks almost always reproduces it, because the cause sits in the input, setting, or record state, not in the attempt.

Compatibility: Agent workflows drafting follow-up mail from call summaries, at current versions

Why it happens

A loop forms when the agent treats a saved draft as unfinished work and the trigger stays true, so each pass creates the same draft again instead of seeing the task as done.

TL;DR

Break the loop for draft a follow-up email from a call summary by giving the agent a done check it cannot argue with: before starting, look for an existing completed output for this exact call id and task, skip if one exists, and cap attempts at two with the failure reason recorded, because the agent kept re-running the same task on the same call and each run reproduced the same output or the same failure.

Compatibility: email service exports and API at current versions, plus the CRM or sharing destination the task names; the steps assume the run can be resumed per call rather than only as a whole batch.

Why it happens

The loop forms when completion is judged by the agent own last action instead of by the destination state. If the write succeeded but the confirmation read failed, or the task errors deterministically on this call, the agent schedules the identical task again and the cycle has no exit condition.
