agent timed out when agent tried to run elementary report generation on full project error

TL;DR

Bound the report before you run it: Elementary report generation over a full project loads every test result and artifact into one process, so generate the report for a selected set of models or a shorter window, and run it outside the agent session. The report is a project-wide aggregation. Inside an agent timeout it needs a scoped input and a checkpointed output, not a bigger timeout alone.

Use this when

• The check or run fails with this symptom: an agent times out generating an Elementary report on a full project.
• You are working on an agent workflow that generates Elementary data quality reports for a large dbt project and the failure repeats on the same data or configuration.
• You need the failing rows, rule, or stage isolated before changing thresholds or code.

Not for this skill when

• A human running the report in CI with no agent timeout, where the full report is acceptable as a batch job.
• The error text names a different tool, stage, or root cause. Match the verbatim error first and use that skill.

Steps

1. Count the models and test results the report would include from the latest artifacts. Verify: the report input size is known
2. Scope the generation with a model selection or a results window. Verify: the scoped report completes inside the limit
3. Move full report generation to a scheduled job and have the agent read the finished report. Verify: the agent consumes the report instead of building it
4. Cache the generated report keyed by the run id so repeat requests reuse it. Verify: a second request returns the cached report without regenerating
5. Record the scope used in the agent summary. Verify: readers know which models the report covered

Variant phrasings

agent timed out elementary report generation full project

The shorter phrasing focused on the named failure.

elementary report generation timeout agent

The symptom phrasing a searcher tries next.

elementary report too large agent timeout fix

The variant naming the failing stage or tool directly.

Compatibility: Elementary report generation with dbt artifacts, agent sessions with fixed timeouts

Why it happens

Report generation aggregates the entire test history in memory and renders every result. Project growth turns a once-fast report into a long batch job, and an agent that launches it synchronously hits its session limit before the render finishes.

Edge cases / pitfalls

• Partial artifacts from a timed-out generation can look like a complete report; check the run id coverage before sharing one.
• Scoping by selection changes which anomalies the report can show; state the selection wherever the report is cited.
