Build a .tar.gz bundle from a policy directory. Supports optimize and revision.
opa_bundle_sign
Sign a bundle with a private key. Returns .signatures.json content.
opa_bundle_verify
Verify the signature of a signed bundle using a public key. Returns { bundle, verified: true }.
opa_compile_query
Partially evaluate a query against the running server.
opa_config
Server configuration (without secrets).
opa_delete_data
Delete a document from the data hierarchy.
opa_delete_policy
Delete a policy by ID.
opa_exec
Batch-evaluate a decision against multiple input files. Returns per-file results with successCount and errorCount.
opa_get_data
Read a path from the data hierarchy.
opa_get_policy
Get a single policy by ID.
opa_health
Liveness / readiness check.
opa_list_policies
List policies registered on the server.
opa_patch_data
Apply a JSON Patch to the data hierarchy.
opa_put_data
Write to a path in the data hierarchy.
opa_put_policy
Upload or replace a policy.
opa_query_decision
POST to a /v1/data/... decision endpoint with input.
opa_status
Bundle / decision-log status.
rego_bench
Run opa bench and return statistical timing data.
rego_capabilities
Return the capabilities (built-ins, future keywords) understood by the bundled OPA.
rego_check
Type-check and validate Rego. Wraps opa check.
rego_check_schema
Check Rego against a JSON Schema. Validates that every input. field the policy reads exists in the schema using opa check --schema. Accepts inline schema or a path to a JSON Schema file on disk.
rego_compile_query
Partially evaluate a query against a policy.
rego_coverage_gaps
Run opa test --coverage and return per-file uncovered line ranges, sorted worst first. Use threshold to focus on files below a target percentage.
rego_deps
Static dependency analysis: rule-level data references and cross-package calls.
rego_describe_policy
Summarize what a policy does, its inputs, decisions, and assumptions.
rego_eval
Evaluate a query against a policy and input. The bread-and-butter tool.
rego_eval_with_coverage
Evaluate with --coverage and return per-line coverage.
rego_eval_with_explain
Evaluate with --explain=full and return a structured trace.
rego_eval_with_profile
Evaluate with --profile and return per-rule timing and evaluation counts.
rego_explain_decision
Walk through every rule that fired (and didn't) for a given query. Wraps regoevalwithexplain and produces a step-by-step natural-language trace.
rego_format
Format Rego source. Wraps opa fmt. Idempotent.
rego_generate_test_skeleton
Given a policy, generate a test.rego skeleton covering each rule.
rego_inspect
Inspect a bundle or directory: packages, rules, annotations. Wraps opa inspect.
rego_lint
Run Regal across a file or directory. Returns findings grouped by category. Requires regal on PATH or REGALBINARY set.
rego_migrate_v1
Migrate Rego v0 source to v1 syntax. Runs opa fmt --rego-v1 then validates with opa check --v1-compatible. Returns { original, migrated, changed, valid, errors }.
rego_parse_ast
Parse Rego to AST JSON. Wraps opa parse.
rego_security_audit
Run regal lint restricted to security and bugs categories across a directory. Returns severity-grouped findings with remediation guidance.
rego_suggest_fix
For a failed regocheck or regolint, propose minimal patches.
rego_test
Run opa test over a directory. Returns pass/fail per test, with optional coverage.
rego_test_multiroot
Run Rego tests across multiple roots. Solves OPA's package-conflict problem for repos with multiple independent namespaces. Supports explicit root lists and scan mode (auto-discovers leaf test roots).
