Skill: req-add

Use this skill when adding a new requirement to an existing requirements-spec under the Assured bundle. Computes the next sequential ID for the feature and module, prompts for the requirement text, and appends a properly-formatted ### REQ-... section.

Inputs

• <feature-id> (or <module-id> for positional projects): which spec to append to
• The requirement text (single declarative sentence)

Steps

1. Locate the requirements-spec. Read docs/specs/<feature-id>/requirements-spec.md. If the project uses positional decomposition, read the spec for the matching module.

2. Compute the next REQ number. Scan existing ### REQ-... headings. New ID is the max + 1, zero-padded to 3 digits.

3. Prompt for the requirement text. Ask: "Single declarative sentence describing the new requirement?"

4. Append the section.

   ### REQ-<feature-id>-<NNN>
   
   <text>
   
   **Module:** <module-id>
   

5. Confirm. Show the diff to the user before saving.

6. Save. Write the file.

7. Remind. "Next steps: add a corresponding DES in design-spec.md (use req-link), then a TEST in test-spec.md."

Done criteria

• New REQ section appended with correct ID, no renumbering of existing IDs.
• Module assignment present.
• File saved; no other changes.
