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
# create_jinx
Write a new .jinx file from inputs (name, description, inputs spec as JSON list of strings, python body). Agents use this mid-task to crystallize a repeated block of code into a reusable jinx. The jinx is written to the team's jinxes/lib dir by default and registered with the running team so it is immediately callable without a restart.
## Inputs
- `jinx_name`
- `description`
- `inputs_spec` (default: `'[]'`)
- `python_code`
- `target_subdir` (default: `'lib'`)
## Steps
- `write_jinx` → [`write_jinx.py`](./write_jinx.py)
## Usage
```
/run_jinx jinx_ref=create_jinx input_values={"jinx_name": "<value>", "description": "<value>", "inputs_spec": "[]", "python_code": "<value>", "target_subdir": "lib"}
```Read the whole file at its exact version.
How to install
mdr add npc-worldwide/npcpy/create_jinx@sha256:1b696ed8477d314fThe line at the top of this page pins the label git:20260418.b4e27cd, 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.
