## 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.

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

## 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.
