Maintain an append-only project INVOICES.csv ledger from explicit billing facts and recorded lifecycle evidence; never infer charges or payment from activity or time logs.

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

# /as:invoice

Before acting, read the [host contract](../../docs/host-harness-contract.md), this component's [declaration](host-contract.json) (`skill:invoice`), and applicable [workspace semantics](../../docs/workspace-model.md). Load only the required modes from the [shared catalog](../../corpus/host-contracts.json).

<!-- architecture-studio:harness-compatibility -->
Use the [host adapter](../../docs/host-adapters.md) and [native context procedure](../project/references/context-resolution.md). The harness performs the semantic operations below using its available native tools; ordinary task-specific code is allowed. No Arch Studio runtime, installer, bridge, supplied script or source checkout is required. Direct skill invocation is valid. Existing exact authorization persists; ask only for material missing facts or unavailable access.

Own INVOICES.csv; invoice documents are registered through receive with kind `invoice`. No agreement is required: amounts and currency may come from confirmed terms in PROJECT.md's Agreement section or explicit user input. Never infer billability, payment, hours or completion from task/time/activity signals.

How to install

The exact contents, by fingerprint

mdr add alpacalabsllc/skills-for-architects/invoice@sha256:9ea25fdbe687b28b

The line at the top of this page pins the label git:20260920.ef0a19e, 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.
