AI-assisted draft. Not a forensic conclusion.

Use this skill only with authorised material and within the user's role, competence, jurisdiction, laboratory procedures and information-handling rules.

When to use this skill

Check DNA submission readiness for identifiers, references, elimination samples, controls, handling records, comparison questions, contamination information, and validated-method status. Use biological-evidence-triage-assistant for pre-testing biological-material recovery and triage. Do not interpret profiles, mixtures, statistics, or contributors.

What to provide

  • exhibit and custody records
  • questioned and reference sample list
  • elimination samples
  • collection and contamination records
  • authority or consent status
  • laboratory acceptance requirements

If a material input is absent, it should remain marked as unknown. The skill must not reconstruct missing facts from narrative fit.

Method

  1. Map every questioned item to its requested comparison and known references.
  2. Check identifiers, seals, packaging, storage and handling history.
  3. Identify missing elimination samples and contamination events.
  4. Check that authority, consent and purpose are recorded without deciding legal sufficiency.
  5. Verify that the laboratory's validated method, software version and interpretation procedure cover the requested examination, recording the source and status rather than assuming validity.
  6. Flag ambiguous comparisons, sample exhaustion risk and missing contextual information.

Direct observations, reported facts, test results, expert interpretations, hypotheses, unknowns, conflicts and exclusions must remain in separate fields.

Outputs

  • DNA readiness report
  • item-reference comparison map
  • contamination checklist
  • authority and documentation gaps
  • laboratory clarification questions

Every material statement should cite an exhibit, file, page, image, timestamp, record, standard or named assumption.

Hard limits

  • Do not interpret profiles, mixtures, likelihood ratios or contributor status.
  • Do not identify a person or infer ancestry or protected traits.
  • Do not promise that a complete submission will yield a result.

The skill must not determine guilt, recommend arrest or coercive action, invent evidence, backfill records, promise admissibility or hide potentially exculpatory, adverse, inconsistent or limiting information.

Required human review

Reviewer: DNA examiner and legal reviewer for authority questions.

The reviewer must approve, amend or reject each material observation and interpretation before operational, laboratory, prosecutorial or court use.

Sample prompt

Use $dna-casework-readiness-checker to identify missing references, elimination samples, handling records, and ambiguous comparison questions.
