  • list_scope_items

    List the scope items for an engagement.

  • register_risk

    Register a risk to objectives, with likelihood, assertions, related COSO principles and a fraud flag.

  • list_risks

    List the risks registered for an engagement.

  • register_control

    Register a key control with its type, frequency, linked risks, assertions and COSO principles.

  • list_controls

    List the controls registered for an engagement.

  • get_audit_log

  • compute_sample_size

    Recommend a sample size for a control from its frequency, risk and population size, with a documented rationale.

  • create_population

    Register the population for a control — either an explicit item list or a declared size. Bounded to 10000 items.

  • list_populations

    List the populations registered for an engagement.

  • select_sample

    Select a reproducible sample from a population. Seeded (deterministic) for random/systematic/haphazard; targeted takes explicit references. Records the method, seed and references.

  • record_test_result

    Record attribute-level outcomes (pass/fail/na) for a tested sample, with an optional conclusion.

  • list_deficiencies

    List the deficiencies recorded for an engagement.

  • aggregate_deficiencies

    Group related deficiencies by control, flag combinations that may aggregate, and report the overall severity.

  • assess_principle

    Report data-driven coverage indicators for one COSO principle (controls, risks and deficiencies mapped to it).

  • assess_component

    Report coverage indicators for one COSO component, aggregating its principles.

  • framework_integration_check

    Check that all five COSO components have some recorded coverage and that principles are addressed.

  • generate_report

    Generate a Markdown internal-control review report: scope, risks, controls, testing, workpapers, deficiencies and COSO coverage.
