jsonbill skillA
jsonbill is agent-read markdown (skill) from quailyquaily/mistermorph: Generate a PDF invoice/statement files from JSON via JSONBill API..
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
# JSONBill (portable, safe)
API base: `https://api.jsonbill.com`
This skill is designed to call the JSONBill REST API **without ever exposing API keys/tokens to the LLM**:
- Do **not** ask the user to paste an API key/token.
- Do **not** place secrets in prompts, logs, or tool parameters.
- Use a **host-side credential mechanism** (e.g. “credential profile”, “secret manager”, “vault”, env var injection) so the agent never sees the secret value.
## Prerequisites (host configuration)
The host must be configured (outside this skill) with:
- A credential profile id (recommended): `jsonbill`
- A secret reference (example): `JSONBILL_API_KEY`
- A binding that injects the credential into HTTP requests (commonly: `Authorization: Bearer <secret>`)
## Endpoints
- Create task: `POST /tasks/docs`
- Poll task: `GET /tasks/{trace_id}`
- PDF URL: `GET /tasks/{trace_id}.pdf` (usually you can return this URL without downloading)
## Portable pseudocode
Notes:
- If the user input is a **local file path**, you MUST read the file and parse its JSON first. Never send local paths to external APIs.
…Read the whole file at its exact version.
How to install
mdr add quailyquaily/mistermorph/jsonbill@git:20260213.ef3fe6emdr add quailyquaily/mistermorph/jsonbill@sha256:31df9381ce50ca1bPin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
