Fill a monthly hourly invoice on Google Sheets from GitHub PRs, Jira tickets, Gmail, and calendar meetings that have a transcript, one tab per month per client. Use when the user mentions an invoice, timesheet, billable hours, logging monthly work, rolling over an invoice month, meeting transcripts, or reconciling PRs and tickets to hours.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# issue-invoice

Monthly hourly invoicing for contract clients. One Google Sheet per client, one
tab per month (`202607`, `202608`, ...). Rows are billable work reconciled from
GitHub PRs, linked to their tracker tickets, plus meeting rows.

Every client-specific value - spreadsheet id, org, repos, Jira host, rate - lives
in a private rules file **outside this repo**. This skill ships no client data.

## Client rules

```
~/.config/vd/invoice-rules/<client>.invoice-rules.md
```

YAML frontmatter is machine-read by the harvest script; the prose below it is for
you. See `references/client.invoice-rules.example.md` for the schema and copy it to
onboard a new client.

```bash
scripts/harvest-prs.py --list          # configured clients
```

Read the whole rules file before drafting rows. It defines the tab layout, column
formats, hour calibration, meeting cadence, and client quirks - all of which vary.

**Never write a client value into this skill.** If something is true for one client
only, it belongs in that client's rules file.

## Workflow

### 1. Read current state first

```bash
export GOG_HOME="$HOME/.config/vd/gog"
ACCT=<gog_account from rules, --account org with --user person>
…

Read the whole file at its exact version.

How to install

The exact contents, by fingerprint
mdr add vanducng/skills/issue-invoice@sha256:1d777c84d7a93876

The line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
