ORIGINAL REPORTING SKILL AUTHORING AND TEST PACKET
All North Street business data is fictional. No Claude invocation, installed Skill, plugin installation, or native report generation is claimed. Claude status: NOT_EXECUTED_IN_CLAUDE.
Deployable authoring source: northstreet-weekly-report/skill-source.txt plus its three references. In a disposable PACKAGE COPY only, rename skill-source.txt to SKILL.md before following the current app ZIP upload or Code project route. Root production coordination handles package preparation; no project/global Skill is edited by this packet.
Do NOT upload this whole exercise folder. tests, expected.json, execution notes, and plugin review packet stay outside the deployable named Skill folder.
App ZIP: one top-level northstreet-weekly-report folder, core and references immediately under it. Exact app route checked October 2; recheck current official docs.
Code project exercise: use a disposable project's .claude/skills/northstreet-weekly-report/SKILL.md. Local project and account-enabled installations are different routes. Do not install in a user's existing production/global scope for this lesson.
Every expected answer is original independently derived reference data, not recorded Claude output. Local file/arithmetic checks are separate from actual invocation and export tests.
No sending, source updates, paid tool calls, credentials in chat, publication, or plugin installation required.

PREPARED PACKAGE
The supplied northstreet-weekly-report.zip and .skill contain only the named Skill folder with SKILL.md and three references. They are prepared and schema-validated, not installed or tested in Claude. Two isolated Codex capability comparisons passed the factual checks in both baseline and Skill-assisted runs; no measured improvement is claimed. Actual Claude package acceptance, selection, invocation, export, unrelated-task and zero-group exercises remain pending. The authoring text source remains unchanged.
