Conciseness

The ~28-line body is lean and assumes Claude's competence: a two-sentence overview, a single exact delegation ("follow the procedure exactly"), and terse troubleshooting entries with no padding or explanation of concepts Claude already knows. Every token earns its place, matching anchor 5.

Actionability

Troubleshooting gives concrete, specific guidance — "`AWSLambdaDynamoDBExecutionRole`", "correct view type", "adjust the batch size" — but the main section is a pointer with no inline commands or examples. This lands at anchor 4 (mostly executable, minor gaps) rather than 5, since copy-paste-ready detail lives only in the reference file.

Workflow Clarity

The single action is unambiguous — "follow the procedure exactly. See [procedure](references/lambda-dynamodb-connection.md)" — and the referenced procedure includes validation steps (dependency verification, infrastructure confirmation, "Test the Setup"). However, the body itself does not surface any verification checkpoint, matching anchor 4 (most checkpoints present, minor validation gaps) rather than 5.

Progressive Disclosure

Verified against the actual bundle: one real, well-structured reference file (references/lambda-dynamodb-connection.md, 230 lines with Parameters, Steps, Examples, Troubleshooting) referenced clearly from both the procedure and troubleshooting sections. One level deep, content appropriately split, easy navigation — anchor 5.

Specificity

Names the domain and several concrete capabilities — "IAM roles, stream event source mapping, and read/write permissions" — with only minor coverage gaps (function deployment and table creation are not mentioned). It falls short of anchor 5's comprehensive coverage but exceeds anchor 3's 1-2 actions.

Completeness

Explicitly answers both "what" ("Connects an AWS Lambda function to DynamoDB with IAM roles, stream event source mapping, and read/write permissions") and "when" with three concrete trigger phrases ("Use when setting up Lambda-DynamoDB integration, processing DynamoDB stream events, or deploying serverless event-driven architectures"). This matches anchor 5 exactly; anchor 4 would require a less explicit "when" clause.

Trigger Term Quality

Includes natural phrases users would say — "Lambda-DynamoDB integration", "DynamoDB stream events", "serverless event-driven architectures" — giving good keyword coverage. A few natural variants are missing (e.g. "trigger Lambda from DynamoDB"), so it does not reach anchor 5's comprehensive synonym coverage.

Distinctiveness Conflict Risk

The Lambda-to-DynamoDB integration niche is clear with distinct triggers, but the trigger "deploying serverless event-driven architectures" is broad and creates minor overlap risk with general serverless or deployment skills. Anchor 4 ("mostly distinct; minor overlap risk") fits better than anchor 5's minimal conflict risk.
