Vue d’ensemble

Use this skill when you need to test or evaluate LangGraph/LangChain agents: writing unit or integration tests, generating test scaffolds, mocking LLM/tool behavior, running trajectory evaluation (match or LLM-as-judge), running LangSmith dataset evaluations, and comparing two agent versions with A/B-style offline analysis. Use it for Python and JavaScript/TypeScript workflows, evaluator design, experiment setup, regression gates, and debugging flaky/incorrect evaluation results.

Core Workflow

Define test scope.

Unit: deterministic logic in one node/function.
Integration: node interactions and routing.
End-to-end: complete response quality on realistic inputs.

Start from deterministic checks.

Mock LLM/tool IO for speed and repeatability.
Keep real-model tests as a smaller, explicit suite.

Build/curate dataset examples.

Use stable inputs and expected outputs.
Keep schema simple: inputs and outputs objects (optional metadata).
Compatibility note: scripts also accept singular keys (input, output) for legacy datasets.

Run evaluation with explicit gates.

Use evaluator keys that map to deployment decisions.
Set thresholds in CI for regression prevention.

Compare versions before rollout.

Run same dataset on both versions.
Check both quality and latency.

Diagnose failures from traces/experiments.

Inspect low-scoring examples.
Split failures by pattern (routing, tool usage, hallucination, latency spikes).

single
sequence
conditional

Decision Rules

If behavior is deterministic and local:

Use unit tests first.

If behavior depends on tool sequence/routing:

Add trajectory evaluation.

If behavior depends on realistic distribution quality:

Run LangSmith dataset evaluation.

If approving a replacement model/prompt/graph:

Run A/B comparison and check both quality and latency.

Common Failure Patterns

Flaky tests

Cause: real-model nondeterminism in unit scope.
Fix: mock LLM/tool calls for unit tests; reserve real-model tests for separate integration marks.

High trajectory variance

Cause: overly strict matching for workflows with equivalent paths.
Fix: switch match mode (unordered, subset, or superset) where appropriate.

Regressions hidden by averages

Cause: only aggregate score monitored.
Fix: inspect per-example failures and segment by category metadata.

Latency regressions with same quality

Cause: no explicit latency gate.
Fix: include latency evaluator and CI threshold.

Minimal Best Practices

Keep fast deterministic tests as the largest share.
Version datasets and keep them stable.
Track both correctness and latency.
Add explicit go/no-go thresholds in CI.
Compare candidate vs baseline before production rollout.
Investigate failures with trace-level evidence, not only aggregate scores.

Preserve the core workflow, adapt paths to this repo, and keep the rule scoped to tasks where it is relevant. Skill purpose: Use this skill when you need to test or evaluate LangGraph/LangChain agents: writing unit or integration tests, generating test scaffolds, mocking LLM/tool behavior, running trajectory evaluation (match or LLM-as-judge), running LangSmith dataset evaluations, and comparing two agent versions with A/B-style offline analysis. Use it for Python and JavaScript/TypeScript workflows, evaluator design, experiment setup, regression gates, and debugging flaky/incorrect evaluation results.
