Draft a spec, PRD, PR description, README section, runbook or technical doc that a reader can act on without a follow-up question: named reader, answer first, typed structure, self-test. Use when the user says write a spec, draft a PRD, write the PR description, or document this.
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
# $ccc-agent-writing — docs a reader can act on **CC Commander** · $ccc-agent-writing · a technical document with one named reader, one outcome, and a passed self-test.

Name the reader and the outcome …

How to install
mdr add kevinzai/commander/ccc-agent-writing@sha256:c58585464fa44d8eThe line at the top of this page pins the label git:20261013.fbe187d, 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.
