agent context overflow during sync the Workday hire feed: context limit

Not specified by the original author.

TL;DR

Stop carrying the whole run in the conversation and move state into tools and storage. The agent overflows because it accumulates every hire record, log, and page it has seen while trying to sync the Workday hire feed. Restructure so each hire is processed in a fresh bounded step, reference data is fetched on demand and summarized, and progress lives in a run store the agent reads back in small pieces.

agent context overflow during sync the Workday hire feed: context limit error

Use this when

• The run fails with a context or token limit error partway through sync the Workday hire feed, later for larger cohorts.
• The agent trace shows long accumulated histories, pasted tables, or full page contents retained across steps.
• Short single-hire runs of the same workflow succeed reliably.

Not for this skill when

• A single hire with one huge source document overflows alone. Split that document handling instead of the whole run design.
• The error is a provider outage mislabelled as a limit. Check provider status before redesigning.

Steps

1. Measure the growth: from the run trace, estimate how much context each hire adds, including tool outputs the agent keeps, and identify the bulkiest contributors such as full directory listings, verbose API responses, or screenshots described in text. Verify: the top context contributors per hire are named with rough sizes
2. Externalize run state: write per-hire status, identifiers, and decisions to a run store such as a table or file the workflow owns, and have the agent read back only the current hire slice instead of remembering the cohort. Verify: the agent completes a hire using only the stored slice plus its instructions
3. Process hires in bounded units: one hire, or a small fixed batch, per agent invocation with a fresh context, orchestrated by a simple loop outside the model that tracks overall progress and handles retries. Verify: a multi-hire test run completes with flat per-invocation context use
4. Shrink tool outputs at the source: request only needed fields from lookups, summarize long lists with counts and the relevant rows, and store large artefacts as references the agent opens only when a decision truly needs them. Verify: sample tool outputs are visibly smaller with no decision-relevant loss
5. Resume the failed cohort with the new structure and confirm the run completes sync the Workday hire feed for every hire, then check output quality on the last hires equals the first, since quiet degradation is the overflow failure mode that does not crash. Verify: first and last hire results pass the same spot checks
6. Set a cohort sizing rule in the runbook from the measured per-hire cost, with headroom, and add a context-use warning in run reporting before the hard limit so growth is caught as a trend. Verify: the sizing rule and the warning both exist

Why it happens

Agent context is a finite working memory, and provisioning runs are naturally unbounded: every hire, lookup, and verification adds text the agent keeps carrying. Designs that let the conversation itself be the database guarantee overflow at some cohort size, usually mid-run on the busiest hiring day. The model does not need to remember the cohort; it needs the current hire, the rules, and a reliable place to put results. External state, bounded invocations, and lean tool outputs are the standard architecture for long agent work, and they also improve consistency because each hire gets the agent full attention.

Variants and edge cases

Reference data is the bulk, not hires

Load catalogues such as app or license lists as searchable tool data the agent queries per decision instead of pasting them into context.

History needed for audit, not for decisions

Keep the full trace in run logs outside the model context; the agent needs conclusions, not its own transcript.

Overflow at the verification step

Verification that re-reads everything the run produced doubles the load. Verify from the target system state per hire at completion time instead.

Compatibility: Applies to LLM agent provisioning workflows processing cohorts of hires. Requires workflow orchestration and run storage access.

TL;DR

Fix this in first week schedule agent by acting on the exact problem first: keep only the hire week dates, working hours and the task list in context, summarise each calendar into busy blocks before deciding slots, discard raw calendar detail after summarising, and assemble the schedule from the busy block summaries. Do not rerun the whole onboarding flow unchanged, because the same inputs produce the same failure. Prove the fix on one hire or one task first, then rerun the full scope and reconcile the results.

context overflow agent failed to assemble a first week schedule for a new hire error context limit failure

Use this when

• The operation in first week schedule agent fails with this exact problem: context overflow agent failed to assemble a first week schedule for a new hire error context limit failure.
• The same failure repeats on retry with unchanged inputs.
• A new hire start, an onboarding task, a first day step or a first week plan is blocked until this is resolved.

Not for this skill when

• The notice is a platform outage from the vendor. Resolve that first, then return here if this problem remains.
• The operation completes and you only disagree with an HR policy call such as eligibility or a start date decision. That is a people team decision, not this failure.

Steps

1. Reproduce the failure on one named hire or task in first week schedule agent and record the full problem text plus the hire, task or start date involved. Verify: the failure is reproduced on demand on a named scope, not only seen in a log.
2. Apply the specific fix for this problem: keep only the hire week dates, working hours and the task list in context, summarise each calendar into busy blocks before deciding slots, discard raw calendar detail after summarising, and assemble the schedule from the busy block summaries. Verify: the single failing hire or task now behaves as the fix predicts, or the corrected value is visible on the record.
3. Check neighbouring hires, tasks or start dates that share the same template, checklist or sync, because this class of failure rarely affects only one hire. Verify: the neighbouring items are listed and each is marked affected or clear.
4. Rerun the original operation in first week schedule agent on the previously failing scope, watching for the same problem rather than assuming success from a quiet log. Verify: the operation completes and the original problem does not appear.
5. Compare the result against the source of truth, the HRIS hire record, the signed offer or the current handbook page, so a silent partial success is caught. Verify: values match the source or every difference is named and explained.
6. Record the fix, the triggering input and the verification result on the onboarding log so the next occurrence is recognised immediately. Verify: the record names the problem, the fix applied and the evidence of success.

How to fix - context overflow agent failed to assemble a first week schedule for a new hire error context limit failure

The how to phrasing for the same failure in first week schedule agent. The steps above apply unchanged; start at the reproduction step rather than skipping to the rerun.

first week schedule agent troubleshooting for this failure

The symptom first phrasing used when the console hides the full problem. Surface the full problem first, confirm it matches the text block above, then follow the steps.

Why it happens

Holding several full calendars plus the task list overflows the context before the schedule is composed, and busy block summaries preserve every constraint the scheduling decision actually uses.

Edge cases

• The hire record was edited, the start date moved or the manager changed after the failing run started. Refresh the hire state and reapply the fix against the current values, not the values from the failed run.
• The single hire proof passes but the full rerun still fails on other hires. Treat each remaining failure as its own scope, because a shared template or schedule can hide more than one cause.
• The source systems disagree on the correct value. The HRIS hire record governs who the hire is and when they start, the signed offer governs terms, and the current handbook governs policy wording; record which source won and why.

Compatibility: first week schedule agent at current versions, plus the HRIS, handbook or onboarding tool the query names; no extra tooling beyond access to the source records needed to verify results.

TL;DR

Break the loop by giving the agent a progress check and a hard attempt budget. The agent is repeating the sync the Workday hire feed step because its success test never passes, usually because it checks the wrong signal or the step result never reaches its state. Add a direct verification read from the SCIM target, stop after a small number of attempts with a clear escalation, and fix the underlying success test so one success ends the step.

agent loop detected: agent kept repeating the same sync the Workday hire feed step

Use this when

• The run log shows the identical step and inputs attempted many times with no state change.
• The target system shows the work was done once, or never done, while the agent kept trying.
• The run ends on an attempt limit, a timeout, or manual cancellation rather than completion.

Not for this skill when

• The agent retries a few times with backoff and then succeeds. That is healthy retry behaviour, not a loop.
• A human keeps restarting the run manually. Fix the operational process instead of the agent.

Steps

1. Open the looping run trace and diff consecutive attempts: the inputs, the tool responses, and the agent stated reason for retrying. Identify the exact success condition the agent believes is unmet. Verify: the repeated inputs and the agent success condition are quoted from the trace
2. Check the SCIM target directly for the step result and compare reality with the agent belief: if the result exists, the agent verification is broken; if it never exists, the create call itself is failing in a way the agent misreads as retryable. Verify: ground truth and the agent belief are contrasted explicitly
3. Fix the verification: replace any indirect signal, such as searching a list page or parsing a chatty response, with a direct read of the created object by its identifier in the SCIM target, and treat a confirmed read as step success. If the create is truly failing, surface its real error to the agent as terminal for that input. Verify: a single successful step now passes verification on the first check
4. Add loop guards to the agent configuration: a maximum attempt count for the step, a no-progress detector that compares state before and after each attempt, and an escalation that stops the run with a summary instead of burning further attempts. Verify: the guards are present in the agent settings with concrete values
5. Re-run the scenario for one hire end to end and confirm the sync the Workday hire feed step executes once, verifies, and the run moves on. Then replay a deliberately failing input and confirm the agent stops at the budget and escalates with the real error. Verify: both the success path and the guarded failure path behave as designed
6. Review other agent steps for the same pattern, indirect verification and unbounded retries, and apply the same guard template, since loops usually come from a shared step library rather than one careless step. Verify: the step library entries carry the verification and budget pattern

Why it happens

Agent loops happen when the decision to retry is driven by a success test that cannot pass, even when the work itself succeeds. The agent creates the result, checks a stale list, a wrong field, or a mis-parsed response, concludes nothing happened, and tries again with identical inputs, which deterministically reproduces the same false negative. Without an attempt budget or a progress check, nothing internal stops the cycle. Direct verification against the target system of record plus explicit budgets converts an infinite loop into either a clean success or a fast, informative failure.

Variants and edge cases

Loop creates duplicates each attempt

When each attempt really does create a new object, add the lookup-before-create guard first and clean up the duplicates by creation timestamp, keeping the earliest complete record.

Loop alternates between two steps

Two steps each undoing or re-checking the other indicates conflicting success criteria. Align both steps on one shared state read before adding budgets.

Loop only for one hire record

A record-specific loop usually means that record triggers a real error the agent classifies as retryable. Log the raw target error for that record and fix its data.

Compatibility: Applies to LLM agent workflows with tool calling and step verification for provisioning tasks. Requires agent configuration access.
