License: a license file GitHub does not identify

Create a detailed execution plan/spec/PRD for implementing features or refactors in a codebase, designed around the program's entrypoints, the doors that carry domain intent, by leveraging existing research in the codebase.

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

You are tasked with creating a spec for implementing a new feature or system change in the codebase by leveraging existing research in the **$ARGUMENTS** path. If no research path is specified, use the entire `research/` directory. IMPORTANT: Research documents are located in the `research/` directory — do NOT look in the `specs/` directory for research. Follow the template below to produce a comprehensive specification as output in the `specs/` folder using the findings from RELEVANT research documents found in `research/`. The spec file MUST be named using the format `YYYY-MM-DD-topic.md` (e.g., `specs/2026-03-26-my-feature.md`), where the date is the current date and the topic is a kebab-case summary. Tip: It's good practice to use the `codebase-research-locator` and `codebase-research-analyzer` agents to help you find and analyze the research documents in the `research/` directory. It is also HIGHLY recommended to cite relevant research throughout the spec for additional context.

How to install

The exact contents, by fingerprint

mdr add bastani-inc/atomic/create-spec@sha256:46b19d134d33d17f

The line at the top of this page pins the label git:20260819.3646705, 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.
