## What it does

The skill catches you up on chat activity after you step away. It skips noise from subagent outputs and system alerts, verifies the current state of PRs or tasks, and describes the outcome in simple language. Instead of raw git hashes or file paths, it delivers a brief summary under 100 words.

Pending decisions get laid out with everything needed to make a choice on the spot. Each item includes the suggested action, risk level, and supporting reasoning. If a visual makes the concept clearer, the skill embeds screenshots or small diagrams of up to six blocks.

Because this turn is strictly read-only, ketchup will never touch code or trigger new builds while building the status update.

# Ketchup

Catch the user up on what changed in this chat since the last message they wrote before `/ketchup`, and help them understand each change, not only where it stands. Then lay out every call waiting on them so they can make it from your reply alone. Notifications and subagent results are not their messages. Assume the user remembers their last message and nothing after it.

Use [`/bro`](../bro/SKILL.md)'s voice, not its task: plain words, short sentences, no jargon, like one person catching up another. Say what changed for the user, not how you did it. Say "the tests pass", not "CI is green". Leave out hashes, file paths, commands, build numbers, and test counts unless the user needs one to act. Call each PR, branch, or agent by a name the user would know, not by a label you invented. If a fact needs context to make sense, give the context or leave the fact out.

## Gather what changed

Keep this turn read-only. Make visuals only from what you already have: do not change code, start an app or a job, or post anything. Collect your own work since that message, reports from subagents, and messages from anyone else in this chat. Check the current state of each PR, CI run, or agent this chat touched. Check each number you will show against the facts it comes from, and say so when you correct one.

An action item is a call or step only the user can take, such as a product choice, an approval, an irreversible action, or access you lack. Include any still waiting on the user, even one raised before their last message. Work you can still do yourself is not an action item. Never make up a call to fill the reply. A step the user did not ask for and the work does not need is not an action item, unless it is irreversible and waiting on the user: give it one line and no visual.

One call can cover many items, such as each PR in a set awaiting merge. For each item, collect its link, what it changes for users, the evidence behind your pick, its risk, and your pick. Write "unknown" for a fact the call needs that you do not know. Leave out a link you do not have.

## Write the reply

Spend words on the calls, not on the story. Keep what happened under 100 words, not counting pictures, and shorter when less happened. Leave out work that changed nothing for the user. Give each item about 30 words. The reply grows with the number of items: two items need well under 150 words in all, not counting pictures, and thirty need far more. Never cut items or shrink them to stay under a word count: no count in place of a list, and no link in place of an item. A link can add depth, but the reply alone must be enough to decide.

Open with one short sentence that names what waits on the user, or says nothing does. The action items give the detail. If nothing happened and nothing waits on the user, say so and stop.
