invoice skillA
invoice is agent-read markdown (skill) from alpacalabsllc/skills-for-architects: 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..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns 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. ## Before changing records …
