Documentation

README

From the original repository

Ketchup 🍅 — alias for /catchup

You found the easter egg. /ketchup is a 1:1 alias for /catchup — condiment-grade catch-up, no behavior change.

Iron Laws

Behave identically to /catchup — this file adds nothing; it only forwards. Never diverge from the canonical skill.
Pass $ARGUMENTS through verbatim — same flags, same defaults.

Execution

Read ${CLAUDE_PLUGIN_ROOT}/skills/catchup/SKILL.md.
Execute that workflow exactly, with this invocation's $ARGUMENTS passed through unchanged (--since, --sources, --depth, --focus all behave the same).
In the brief's footer line, you may render the generator as /ketchup 🍅 instead of /catchup — the only cosmetic difference.

That's it. One condiment, same nutrition.
