/dev-issue — Bootstrap an issue implementation

Compresses the manual gh issue view → grep → handwritten brief → branch → synapse spawn ritual into a single slash command. The skill is a procedural guide for Claude to execute, not an automation script — Claude reads the issue, reasons about scope, and constructs the brief.

Usage

/dev-issue <number>            # default: spawn codex with the brief
/dev-issue <number> --solo     # don't spawn; parent (you) implements
/dev-issue <number> --dry-run  # generate brief only; no branch, no spawn

<number> accepts:

• bare integer: 467
• hash form: #467
