- expense-policymohitagw15856/pm-claude-skillsWrite a clear company expense & reimbursement policy. Use when asked to write an expense policy, a reimbursement policy, a travel & expense (T&E) policy, or spending guidelines.

Not tax/legal advice.FinanceNo warnings★ 1.5K↓ —
- brief-buildermohitagw15856/pm-claude-skillsInterview the user with sharp, one-at-a-time questions to turn a vague request into a tight, complete brief any other skill can run on. Use when a request is fuzzy, under-specified, or 'help me think this through', or before running a skill that needs inputs the user hasn't given. Produces a structured brief (goal, audience, constraints, success criteria) and hands off to the right skill — by interrogating, not guessing.PlanningNo warnings★ 1.5K↓ —

- openqodexopenqodex/openqodexCode review for the current change, before it is pushed. One command runs the security, secret, dependency and lint scanners that fit the changed files, a separate reviewer that checks every scanner finding and is given every changed line, and prints a short receipt with the path of the full report. Use before every git push, when asked for a code review, a security scan, or to review changes, a diff or a pull request, and when a push was blocked or warned by OpenQodex.SecurityNo warnings★ 1.1K↓ —Also in 2 other repos
