Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

Tools (39)

add_review_noteAdd a reviewer note to a workpaper.
add_scope_itemAdd a significant account/process to the review scope, with its objective category and assertions.
aggregate_deficienciesGroup related deficiencies by control, flag combinations that may aggregate, and report the overall severity.
assemble_workpaperAssemble a Markdown control-testing workpaper from the control, its risks, population, sample, test results and exceptions.
assess_componentReport coverage indicators for one COSO component, aggregating its principles.
assess_principleReport data-driven coverage indicators for one COSO principle (controls, risks and deficiencies mapped to it).
classify_deficiencyClassify a control deficiency as deficiency / significant deficiency / material weakness from likelihood × magnitude (escalates for a pervasive control).
compute_sample_sizeRecommend a sample size for a control from its frequency, risk and population size, with a documented rationale.
create_engagementCreate a new internal-control review engagement. Returns the engagement id used by all later tools.
create_populationRegister the population for a control — either an explicit item list or a declared size. Bounded to 10000 items.
framework_integration_checkCheck that all five COSO components have some recorded coverage and that principles are addressed.
generate_reportGenerate a Markdown internal-control review report: scope, risks, controls, testing, workpapers, deficiencies and COSO coverage.
get_activity_logReturn the append-only activity log for an engagement, plus a Markdown rendering.
get_audit_logReturn the append-only audit events recorded for an engagement.
get_componentReturn a single COSO component by id, with its principles.
get_engagementReturn an engagement by id.
get_principleReturn a single COSO principle by framework number or slug, including its paraphrased points of focus.
get_server_infoReturn the server identity, the COSO framework it covers, and the mandatory disclaimer.
get_workpaperReturn a workpaper including its rendered Markdown.
list_assertionsList the assertions used to frame control objectives: completeness, existence/occurrence, accuracy, valuation, obligations/rights, presentation/disclosure.
list_componentsList the five components of the COSO Internal Control—Integrated Framework (ICIF-2013).
list_controlsList the controls registered for an engagement.
list_deficienciesList the deficiencies recorded for an engagement.
list_engagementsList all engagement ids and titles.
list_exceptionsList the exceptions recorded for an engagement.
list_objective_categoriesList the three COSO objective categories (operations, reporting, compliance).
list_populationsList the populations registered for an engagement.
list_principlesList the 17 principles of the COSO ICIF-2013, optionally filtered to a single component.
list_risksList the risks registered for an engagement.
list_scope_itemsList the scope items for an engagement.
list_test_resultsList the test results recorded for an engagement.
list_workpapersList the workpapers assembled for an engagement.
note_exceptionRecord an exception identified during testing, with root cause, impact and any compensating control.
record_test_resultRecord attribute-level outcomes (pass/fail/na) for a tested sample, with an optional conclusion.
register_controlRegister a key control with its type, frequency, linked risks, assertions and COSO principles.
register_riskRegister a risk to objectives, with likelihood, assertions, related COSO principles and a fraud flag.
resolve_review_noteMark a review note resolved on a workpaper.
select_sampleSelect a reproducible sample from a population. Seeded (deterministic) for random/systematic/haphazard; targeted takes explicit references. Records the method, seed and references.
sign_offRecord a preparer or reviewer sign-off. Warns (does not block) if the same person prepared and reviewed.
