| add_scope_item | Add a significant account/process to the review scope, with its objective category and assertions. | Not declared |
| aggregate_deficiencies | Group related deficiencies by control, flag combinations that may aggregate, and report the overall severity. | Not declared |
| assemble_workpaper | Assemble a Markdown control-testing workpaper from the control, its risks, population, sample, test results and exceptions. | Not declared |
| assess_component | Report coverage indicators for one COSO component, aggregating its principles. | Not declared |
| assess_principle | Report data-driven coverage indicators for one COSO principle (controls, risks and deficiencies mapped to it). | Not declared |
| classify_deficiency | Classify a control deficiency as deficiency / significant deficiency / material weakness from likelihood × magnitude (escalates for a pervasive control). | Not declared |
| compute_sample_size | Recommend a sample size for a control from its frequency, risk and population size, with a documented rationale. | Not declared |
| create_engagement | Create a new internal-control review engagement. Returns the engagement id used by all later tools. | Not declared |
| create_population | Register the population for a control — either an explicit item list or a declared size. Bounded to 10000 items. | Not declared |
| framework_integration_check | Check that all five COSO components have some recorded coverage and that principles are addressed. | Not declared |
| generate_report | Generate a Markdown internal-control review report: scope, risks, controls, testing, workpapers, deficiencies and COSO coverage. | Not declared |
| get_activity_log | Return the append-only activity log for an engagement, plus a Markdown rendering. | Not declared |
| get_audit_log | Return the append-only audit events recorded for an engagement. | Not declared |
| get_component | Return a single COSO component by id, with its principles. | Not declared |
| get_engagement | Return an engagement by id. | Not declared |
| get_principle | Return a single COSO principle by framework number or slug, including its paraphrased points of focus. | Not declared |
| get_server_info | Return the server identity, the COSO framework it covers, and the mandatory disclaimer. | Not declared |
| get_workpaper | Return a workpaper including its rendered Markdown. | Not declared |
| list_assertions | List the assertions used to frame control objectives: completeness, existence/occurrence, accuracy, valuation, obligations/rights, presentation/disclosure. | Not declared |

| list_engagements | List all engagement ids and titles. | Not declared |
| list_exceptions | List the exceptions recorded for an engagement. | Not declared |
| list_objective_categories | List the three COSO objective categories (operations, reporting, compliance). | Not declared |
| list_populations | List the populations registered for an engagement. | Not declared |
| list_principles | List the 17 principles of the COSO ICIF-2013, optionally filtered to a single component. | Not declared |
| list_risks | List the risks registered for an engagement. | Not declared |
| list_scope_items | List the scope items for an engagement. | Not declared |
| list_test_results | List the test results recorded for an engagement. | Not declared |
| list_workpapers | List the workpapers assembled for an engagement. | Not declared |
| note_exception | Record an exception identified during testing, with root cause, impact and any compensating control. | Not declared |
| record_test_result | Record attribute-level outcomes (pass/fail/na) for a tested sample, with an optional conclusion. | Not declared |
| register_control | Register a key control with its type, frequency, linked risks, assertions and COSO principles. | Not declared |
| register_risk | Register a risk to objectives, with likelihood, assertions, related COSO principles and a fraud flag. | Not declared |
| resolve_review_note | Mark a review note resolved on a workpaper. | Not declared |
| 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. | Not declared |
