Build Features from Momentic Specifications

Feature changes can drift from intended product behavior when implementation begins before end-to-end specifications. This skill defines focused Momentic tests first and validates durable checkpoints.

Install with my Agent

Copy this request to your Agent. It includes the canonical Skill page and manifest.

Agent request
Review the Skillstore skill "momentic-spec" from https://skillstore.io/skills/momentic-ai-momentic-spec.md and its manifest at https://skillstore.io/api/skills/momentic-ai-momentic-spec/manifest. Verify the artifact. You may proceed after verification, subject to the environment's own policy.

Your Agent should still show its plan and request any confirmation required by the security policy.

Test it

Using "momentic-spec". Add account deletion with a confirmation step.

Expected outcome:

  • Affected test: account-settings-delete, changed to specify confirmation and final account removal.
  • The specification is written before product code changes.
  • The test remains disabled until the deletion workflow and deterministic account setup are complete.

Using "momentic-spec". Validate the completed search filter feature.

Expected outcome:

  • The existing search-filters test is enabled because the complete workflow is now available.
  • Required records and permissions are prepared through established test setup.
  • Proposed run: only search-filters, after explicit confirmation.

Using "momentic-spec". Change a shared authentication module used by several tests.

Expected outcome:

  • Every consuming test is identified before the shared module changes.
  • Unrelated setup and assertions remain unchanged.
  • Fast checks run during implementation, while Momentic execution waits for a durable checkpoint.

What You Can Build

Specify a New User Journey

Create a focused Momentic test that defines expected behavior before implementation begins.

Update Changed Product Behavior

Revise existing Momentic coverage to express a changed contract without weakening unrelated assertions.

Prepare Reliable End-to-End Validation

Define deterministic data, permissions, integrations, and test-only setup for a durable checkpoint.

Try These Prompts

Identify Affected Tests 
Review this feature request and list each affected Momentic test path, its status, and the evidence for including it.
Write the Specification First 
Create or update the smallest Momentic test specification for this behavior. Preserve unrelated setup and explain any disabled state.
Implement from the Test Contract 
Review the Momentic test diff as the product contract, then implement the feature and run appropriate fast repository checks.
Prepare a Durable Checkpoint 
Establish deterministic prerequisites, enable tests expected to pass, and propose the smallest Momentic run with expected cost and duration.

Best Practices

  • Treat the test diff as the product contract before implementation.
  • Reuse established modules and repository conventions for setup and known subflows.
  • Request confirmation before each Momentic run unless iterative reruns were explicitly authorized.

Avoid

  • Do not weaken assertions to match incomplete or incorrect implementation.
  • Do not hide reusable setup inside one large AI action goal.
  • Do not expose test setup capabilities in production or weaken production authorization.

Frequently Asked Questions

Does this skill write tests before product code?
Yes. It requires affected Momentic specifications to be on disk before product implementation begins.
Will it run Momentic tests automatically?
No. It proposes a specific run and waits for explicit confirmation because execution can consume time and credits.
How does it choose affected tests?
It starts with named tests, traces shared behavior, and expands coverage only when repository evidence shows direct impact.
Can a future test remain disabled?
Yes. The handoff must state why it is disabled and what condition allows it to be enabled.
Does it support Momentic v1 tests?
Yes. It directs v1 changes through Momentic MCP tools instead of direct YAML editing.
What validation runs during implementation?
It uses faster repository checks such as unit tests, type checking, and linting before proposing end-to-end execution.
