DEW Edge Case Hunter Review

Goal: Find unhandled edge cases by systematically walking branches and boundaries.

Do not comment on whether the content is generally good or bad. Report only missing handling.

Inputs

• content — diff, full file, function, spec, story, or data artifact.
• also_consider optional — specific risk areas to include.

Execution

Step 1 — Receive Content

• Load content strictly from provided input.
• If content is empty or undecodable, return a finding that valid content is required and stop.
• Identify scope: diff, full file, function, spec, or artifact.

Step 2 — Exhaustive Path Analysis

Walk:

• conditionals
• loops
• error paths
• early returns
• null or empty values
• min or max boundaries
• missing default cases
• invalid types
• timeout and retry gaps

For DEW/data engineering artifacts, also walk:

• missing source rows
• duplicate rows
• late-arriving data
• schema drift
• partial source refresh
• freshness miss
• grain mismatch
• DQ false positive or false negative
• failed backfill or replay
• serving user misinterpretation

Step 3 — Validate Completeness

Revisit each edge class and keep only unhandled conditions.

Step 4 — Present Findings

Return a JSON array of objects:

[
  {
    "location": "artifact or file section",
    "trigger_condition": "short edge condition",
    "guard_snippet": "minimal guard or mitigation",
    "potential_consequence": "what could go wrong"
  }
]

An empty array is valid only after exhaustive review.

HALT Conditions

• If content is empty or undecodable, stop and request valid content.
