QA Hold Ageing and Release-Priority Agent

The agent ranks every held and quarantined lot by how close it is to expiry and by the single item blocking its release. For each lot it names that one blocker, whether a pending test, an open deviation, or a missing signature, and suggests which to clear next. QA reviews the board, acts, and signs off releases.

The Problem

The lot expired on hold. Nobody saw it ageing until the write-off.

Lots go on hold and quarantine and then sit. The release order follows whoever shouts loudest, not which lot is closest to expiry. One month later a good lot is written off because a single missing signature was never chased. Meanwhile a lot with weeks of shelf life left jumped the queue.

What Changes

The hold board, ranked by what is ageing and what is blocking it.

The agent reads the hold and quarantine list with manufacture and expiry dates, then pulls the open items against each lot: pending tests, open deviations, missing signatures. It ranks the lots most at risk of expiring first and names the single blocker that would release each one. It suggests which lot to clear next, and QA acts on it.

Humans stay in control: The agent ranks the holds and names the blocker for each lot. Your QA team decides what to clear, acts on it, and signs every release. The agent moves nothing and releases nothing.

WHAT YOUR TEAM PROVIDES ONCE

Hold and quarantine list - lots currently blocked from release
Manufacture and expiry dates - shelf life per held lot
Pending tests - QC results still outstanding per lot
Open deviations - unresolved investigations tied to a lot
Missing signatures - batch record approvals not yet signed

What happens day-to-day: Each morning the agent rebuilds the hold board from the ERP hold list and the QMS open items. It ranks the lots by how close they are to expiry and names the one blocker holding each back. QA opens the board, sees which lot is about to age out and exactly what to chase, and clears it. Every release is still reviewed and signed by QA.

ERP (SAP / Tally / Oracle)Read: hold list, lot dates. Write: none

LIMS (LabWare / LabVantage)Read: pending test status. Write: none

QMS (TrackWise / Veeva / MasterControl)Read: deviations, signatures. Write: none

Notification channel (Teams / Slack / email)Read: none. Write: ranked hold board

WITHOUT PMS API

From a hold-list export and a deviations spreadsheet it still ranks by expiry and names blockers, with test status pasted in by QA. Less current, still useful.

WITH PMS API

Connected to the ERP hold list, LIMS test status, and the QMS open items, the agent rebuilds a ranked board with a live blocker per lot every morning. Best experience.

For the person who wants to build this agent step by step. Each node below maps to an n8n workflow node.

TRIGGERNode 1

Trigger - daily refresh

n8n Schedule node running each morning, plus a Webhook for on-demand rebuilds.

Output: { run_time, on_demand }

APINode 2

API - pull hold list

HTTP Request to ERP/LIMS for held and quarantined lots with manufacture and expiry dates.

Output: { lots: [{ lot_id, product, mfg_date, expiry_date, hold_since }] }

APINode 3

API - read QMS open items

HTTP Request to the QMS for pending tests, open deviations, and missing signatures per lot.

Output: { lot_id, pending_tests, open_deviations, missing_signatures }

LLMNode 4

LLM - rank and find blocker

LLM node (Claude) that scores ageing risk and names the single blocker per lot.

Output: { today, ranked: [{ lot_id, days_to_expiry, days_on_hold, blocker, reason, clear_next }] }

You are a QA hold-board analyst at a chemical plant. Given held lots with dates and their open items, rank the lots by ageing risk and name the single blocker that, if cleared, would release each lot.

Today: {today}
Held lots: {lots_json}
Open items per lot: {open_items_json}

For each lot, compute days to expiry and days on hold. Rank most at risk of expiring first. Name exactly one blocker per lot from: pending_test, open_deviation, missing_signature. Add a short reason and a clear-this-next flag on the single most urgent lot. Do not release or dispose of any lot.

Respond ONLY with valid JSON. No explanation.

INPUT

Today 2026-08-18. Lots: L-77 expiry 2026-08-25 hold_since 2026-07-30, pending_test=1 deviations=0 signatures=1; L-52 expiry 2026-11-01 hold_since 2026-08-15, pending_test=0 deviations=1 signatures=0.

OUTPUT

{"today":"2026-08-18","ranked":[{"lot_id":"L-77","product":"Resin C","days_to_expiry":7,"days_on_hold":19,"blocker":"missing_signature","reason":"Only 7 days to expiry and a batch record signature is the sole item left; test result is due the same day.","clear_next":true},{"lot_id":"L-52","product":"Additive K","days_to_expiry":75,"days_on_hold":3,"blocker":"open_deviation","reason":"Long shelf life remaining; open deviation is the block but not yet urgent.","clear_next":false}]}

DECISIONNode 5

Decision - at risk before expiry?

IF node flagging lots whose remaining shelf life is below the review threshold for priority handling.

Output: { at_risk: true|false }

ACTIONNode 6

Action - route board to QA

Post the ranked board to the QA Slack/Teams channel or send it as an email digest.

Output: { sent: true, lots_ranked, channel }
