  • list_principles List the 17 principles of the COSO ICIF-2013, optionally filtered to a single component.
  • get_principle Return a single COSO principle by framework number or slug, including its paraphrased points of focus.
  • get_component Return a single COSO component by id, with its principles.
  • list_objective_categories List the three COSO objective categories (operations, reporting, compliance).
  • list_assertions List the assertions used to frame control objectives: completeness, existence/occurrence, accuracy, valuation, obligations/rights, presentation/disclosure.
  • create_engagement Create a new internal-control review engagement. Returns the engagement id used by all later tools.
  • get_engagement Return an engagement by id.
  • list_engagements List all engagement ids and titles.
  • add_scope_item Add a significant account/process to the review scope, with its objective category and assertions.
  • 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 Return the append-only audit events recorded for an engagement.
  • 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_test_results List the test results recorded for an engagement.
  • note_exception Record an exception identified during testing, with root cause, impact and any compensating control.

  • get_activity_log Return the append-only activity log for an engagement, plus a Markdown rendering.
  • classify_deficiency Classify a control deficiency as deficiency / significant deficiency / material weakness from likelihood × magnitude (escalates for a pervasive control).
  • 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.
