monthly-invoice-summary_skill

Overview

This skill generates client-friendly monthly invoice summaries by analyzing Git commits and time sheet notes. It translates technical activity into concise, business-focused bullet points suitable for client invoicing and status reports. Use it to produce clear monthly billing descriptions that highlight outcomes and value.

How this skill works

The skill asks for project name, time period, previous month summary (optional), time sheet notes (optional), and repository location. It runs a git log over the specified date range, groups commits into categories (feature work, bug fixes, dependency updates, docs, tests), and merges these with time sheet items like meetings and planning. Finally it synthesizes grouped items into 5–10 client-facing bullets, matching tone and recurring items from prior summaries.

When to use it

• Preparing monthly invoices or billing descriptions for a client
• Creating a concise project status for a stakeholder or account manager
• Summarizing development work for non-technical audiences
• Combining time sheets and commits into a single billing note
• Before sending monthly retainers or progress invoices

Best practices

• Provide project name and exact time period up front to avoid back-and-forth
• Attach previous month's summary if you want consistent wording and recurring items
• Include time sheet notes for meetings, planning, and research not in commits
• Keep commit access or repo path available so git log can be run for the date range
• Aim for 5–10 bullets and group related technical work into single value-focused lines

Example use cases

• Generate August invoice summary combining commits and timesheet entries
• Create billing notes for a sprint that spanned two weeks of a month
• Produce a client-friendly description after a release that included dependency updates
• Summarize recurring status meetings and project management for monthly billing
• Convert a series of bug-fix commits into a single line describing resolved issues
