Say what you want

What do you want to make?

Help me keep track of the hours I work. Keep the people who do the work, my clients, my projects (each optionally for a client, and billable or not by default), and time entries: who, which project, a start and end time, a short description and whether it's billable. An entry starts as a draft and counts once I submit it.

Views: today, this week, a calendar of entries by day, a bar chart of hours per day over the last two weeks, totals by project and by client, drafts, and a full entry history. My week starts on Monday.

Remind me every Monday at 8 am to review my hours and plan the week.

Rules: an entry needs a description, ends after it starts, isn't in the future, and covers at most 24 hours on one day. One person's submitted entries can't overlap, though back-to-back entries and two people at once are fine. Submitted entries can't be edited or deleted: void one with a reason and log a replacement. Days and weeks follow my time zone, including daylight-saving changes. Inactive people, clients and projects can't take new entries.

Write these as tests first. Ask me rather than invent names, amounts or dates.

Instructions for your AI

Use my pebblebase connector. If its tools are not available in this chat, stop and give me this link to add it in Claude: https://claude.ai/customize/connectors?modal=add-custom-connector&connectorName=pebblebase&connectorUrl=https%3A%2F%2Fmcp.pebblebase.dev%2Fmcp (or tell me to add https://mcp.pebblebase.dev/mcp as a custom connector under Customize → Connectors), then tell me to start a new chat and paste this prompt again. You cannot add the connector for me. Setup steps: https://pebblebase.dev/pebblebase/agent-guide.md. Never ask me to paste passwords, passkeys, or tokens. Look for an existing project before creating another. Save its records and usage instructions for future chats. Only confirm a save after a successful tool result.

Paste into a new Claude chat.
