Prophet ontology tooling CLI

---

prophet-cli

prophet-cli is the tooling package for Prophet's ontology workflow:

1. Parse DSL (path configured via project.ontology_file)
2. Validate model semantics
3. Build canonical IR (.prophet/ir/current.ir.json) including versioned query_contracts
4. Generate deterministic artifacts (gen/sql, gen/openapi, gen/turtle, gen/migrations, gen/spring-boot, gen/node-express, gen/python)
5. Check compatibility against baseline IR

Main project repository:

• https://github.com/Chainso/prophet

Install

From PyPI:

python3 -m pip install --upgrade prophet-cli
prophet --help

From source (editable):

From repo root:

python3 -m venv .venv --system-site-packages
.venv/bin/pip install --no-build-isolation -e ./prophet-cli

Run via venv script:

.venv/bin/prophet --help

Commands

prophet init

Creates starter prophet.yaml and internal .prophet directories.

prophet init

prophet validate

Parses + validates ontology references, IDs, states/transitions, action contracts, list types, and action/event/trigger links.

prophet validate

prophet plan

Computes deterministic file changes without writing files.

prophet plan
prophet plan --show-reasons
prophet plan --json

prophet check

Runs a CI-style gate in one command:

1. ontology validation
2. generated output cleanliness check
3. compatibility/version-bump check against baseline IR

prophet check
prophet check --show-reasons
prophet check --json
prophet check --against .prophet/baselines/main.ir.json

--json emits structured diagnostics for CI bots and automation.

prophet stacks

Lists supported stack ids, framework/ORM pairings, implementation status, and capability metadata. Entries come from a schema-validated stack manifest. Schema reference:

• user-facing: docs/reference/generation.md
• developer-facing: docs/developer/codegen-architecture.md

prophet stacks
prophet stacks --json

prophet hooks

Lists generated extension hook surfaces from gen/manifest/extension-hooks.json. Useful for wiring user-owned implementations against generated interfaces. Safety/reference docs:

• docs/reference/generation.md

prophet hooks
prophet hooks --json

prophet generate / prophet gen

Writes generated artifacts and current IR.

prophet generate
prophet gen
prophet gen --skip-unchanged

Also syncs generated Spring artifacts into examples/java/prophet_example_spring when present.

Stack selection is configured in prophet.yaml:

generation:
  stack:
    id: java_spring_jpa

Generator implementations are available for all declared stack ids:

• java_spring_jpa
• node_express_prisma
• node_express_typeorm
• node_express_mongoose
• python_fastapi_sqlalchemy
• python_fastapi_sqlmodel
• python_flask_sqlalchemy
• python_flask_sqlmodel
• python_django_django_orm Allowed generation.stack keys are: id, language, framework, orm.

Equivalent tuple form is also supported:

generation:
  stack:
    language: java
    framework: spring_boot
    orm: jpa

Default generated targets:

• sql
• openapi
• spring_boot
• flyway
• liquibase
• manifest (generated file ownership + hashes)

Optional cross-stack target:

• turtle -> gen/turtle/ontology.ttl

Turtle output details:

• emits prophet.ttl-aligned triples (prophet: + std: vocabularies)
• local namespace prefix is derived from ontology name
• custom type constraints are emitted as SHACL NodeShape resources
• conformance can be checked with pyshacl (see docs/reference/turtle.md)

When baseline IR differs from current IR, Prophet also emits delta migration artifacts:

• gen/migrations/flyway/V2__prophet_delta.sql
• gen/migrations/liquibase/prophet/0002-delta.sql
• gen/migrations/delta/report.json

Delta SQL includes safety flags and warnings (destructive, backfill_required, manual_review) as comments. Delta report JSON includes:

• summary counts (safe_auto_apply_count, manual_review_count, destructive_count)
• structured findings entries with classification and optional suggestions
• heuristic rename hints (object_rename_hint, column_rename_hint) for manual migration planning

Generated ownership manifest:

• gen/manifest/generated-files.json
• includes stack metadata and deterministic hashes for generated outputs

Generated extension hook manifest:

• gen/manifest/extension-hooks.json
• lists generated extension points (for example action handler interfaces + default classes)

Spring runtime migration wiring is auto-detected from the host Gradle project:

• if Flyway dependency/plugin is present, Prophet syncs Flyway resources
• if Liquibase dependency/plugin is present, Prophet syncs Liquibase resources
• if neither is present, migration files are still generated under gen/migrations/** but not auto-wired into Spring runtime resources

prophet gen --wire-gradle

Auto-wires the current Gradle project as a multi-module setup:

• adds :prophet_generated in settings.gradle.kts/settings.gradle
• maps it to gen/spring-boot
• adds app dependency implementation(project(\":prophet_generated\")) in build.gradle.kts

prophet gen --wire-gradle

Wiring is idempotent (safe to run repeatedly).

prophet generate --verify-clean

CI mode. Fails if committed generated files differ from current generation.

prophet generate --verify-clean

prophet gen --skip-unchanged

Skips no-op regeneration when the current config + IR signature matches the last successful generation cache.

• cache file: .prophet/cache/generation.json
• ignored when --wire-gradle is used
• incompatible with --verify-clean

prophet gen --skip-unchanged

prophet clean

Removes generated artifacts from current project.

Default removals:

• gen/
• .prophet/ir/current.ir.json
• .prophet/cache/generation.json
• src/main/java/<base_package>/<ontology_name>/generated
• src/main/resources/application-prophet.yml
• src/main/resources/schema.sql (only if it looks generated)
• src/main/resources/db/migration/V1__prophet_init.sql (if generated)
• src/main/resources/db/migration/V2__prophet_delta.sql (if generated)
• src/main/resources/db/changelog/** Prophet-managed generated files, including 0002-delta.sql
• Gradle multi-module wiring for :prophet_generated in settings.gradle(.kts) and build.gradle(.kts)

prophet clean
prophet clean --verbose
prophet clean --remove-baseline
prophet clean --keep-gradle-wire

prophet version check

Compares current IR against baseline and reports compatibility + required bump.

prophet version check --against .prophet/baselines/main.ir.json

Compatibility rules used by CLI are documented in:

• docs/reference/compatibility.md

Expected Project Files

• prophet.yaml
• <your ontology file> (configured in project.ontology_file)
• .prophet/baselines/main.ir.json
• .prophet/ir/current.ir.json (generated)
• gen/ (generated)

DSL Notes

• Field types support scalars, custom types, object refs (ref(User)), lists (string[], list(string)), and reusable struct types.
• Nested list types are supported (for example string[][], list(list(string))).
• name "..." metadata provides human-facing display labels while technical symbols remain the wire/reference keys.
• Description metadata supports both description "..." and documentation "...".
• Object keys support field-level and object-level declarations:
  • key primary
  • key primary (fieldA, fieldB) (composite)
  • key display (fieldA, fieldB) (lookup/index hint)
• SQL/Flyway/Liquibase generation emits a non-unique idx_<table>_display index when an explicit display key is declared and it is not identical to the primary key columns.
• Node Prisma and Mongoose generation also emits non-unique display-key indexes.
• Generated Java record component order follows DSL field declaration order.
• Actions are not auto-implemented; generated endpoints call handler beans.
• Generated action services (generated.actions.services.*) are the API boundary used by controllers.
• Default generated services delegate to handler beans; generated default handler stubs throw UnsupportedOperationException until user handlers are provided.

Config (prophet.yaml)

• No-op benchmark script: scripts/benchmark_noop_generation.py
• Spring query APIs generated by v0.1 include:
  • GET /<objects>/{id} for single-field primary keys
  • GET /<objects>/{k1}/{k2}/... for composite primary keys
  • GET /<objects> with pagination/sort only
  • POST /<objects>/query with typed filter DSL (eq, in, gte, lte, contains) for all filtering
  • list responses returned as generated *ListResponse DTOs (no raw Spring Page payload)
• Generated Spring query layer now uses dedicated generated.mapping.*DomainMapper classes for entity-to-domain mapping.
• Example Spring app includes both h2 (default) and postgres runtime profiles with context tests for both.
