Summary

Adds scripts/check-grader-scores.ts — a manual e2e post-processor that walks examples/**/*.grader-scores.yaml, finds the sibling *.results.jsonl produced by a prior agentv eval --out run, and asserts each (test_id, grader, range) tuple falls within the expected score range.

Motivation from #1185: the screenshot-pii-upload red-team suite has test cases expected to fail against frontier models. Without this script, grader regressions (false positives / false negatives) are invisible in CI.

Changes

  • scripts/check-grader-scores.ts — auto-discovers grader-scores files, reads JSONL, asserts ranges, exits non-zero on failure
  • examples/red-team/archetypes/coding-agent/suites/screenshot-pii-upload.grader-scores.yaml — anchors the format on feat(red-team): screenshot PII upload eval for coding agents #1185 evals
  • examples/features/rubric/evals/dataset.grader-scores.yaml — proves the tool is general
  • AGENTS.md — adds a "Checking Grader Score Ranges" workflow section
  • .gitignore — ignores examples/**/*.results.jsonl (runtime artifacts)

No changes to packages/core, no schema changes, no changes to existing eval YAMLs.

Closes #1190

Adds scripts/check-grader-scores.ts — a manual e2e tool that walks
examples/**/*.grader-scores.yaml, reads the sibling *.results.jsonl
produced by a prior agentv eval --out run, and asserts each
(test_id, grader, range) tuple matches expected score ranges.

Ships two grader-scores sidecar files:
- examples/red-team/archetypes/coding-agent/suites/screenshot-pii-upload.grader-scores.yaml
- examples/features/rubric/evals/dataset.grader-scores.yaml

Also updates AGENTS.md with a workflow section and gitignores
examples/**/*.results.jsonl.

Closes #1190
