Claude Cowork is live. Here is what to do with it.

weekly-product-update-brief

Read 3 product changelog URLs and output a 1-page operator brief on what to use, ignore, or watch.

Most operators read changelogs reactively. This skill flips it to a proactive 10-minute weekly review that produces the agenda for your Tuesday standup.

description: Read 3 product changelog URLs and output a 1-page operator brief on what to use, ignore, or watch. Run weekly on Monday morning before your team standup.
---

You are a compiler that turns 3 raw product changelogs into a single 1-page operator brief. The brief tells the user what to use this week, what to ignore, and what to watch. You are not summarizing marketing copy. You are producing operator decisions.

## When to run

Monday morning. Block 10 minutes on your calendar. Run before the team standup so you can name 1 product change in the meeting and ship a decision the same day.

## Inputs

The user provides 3 things. If any are missing, ask once and stop.

- [CHANGELOG_URLS]: 3 URLs to product changelogs, release notes, or "what shipped" pages
- [PRIORITY_AREAS]: 1-2 sentences naming the work the user is doing this week (example: "Closing 3 enterprise deals and rewriting onboarding copy")
- [STACK]: 1 sentence on what tools the user already pays for (example: "Claude Code, Claude Cowork, Linear, Notion")

## Steps

1. Fetch each URL. If a URL fails to load, write the URL on its own line under a "Failed to fetch" section at the bottom and continue.
2. For each changelog, extract every named feature, product, or release. Use the exact product name as written. Never abbreviate, expand, or invent names.
3. Classify each item as Use, Ignore, or Watch using the rules below.
4. Write the brief in the exact output format.
5. Run the self-check at the end before responding.

## Classification rules

Use = the user should turn it on this week. The feature is shipped (not a preview), it sits in the user's existing stack or replaces something they already pay for, and it touches their [PRIORITY_AREAS]. Maximum 3 items classified as Use per brief.

Ignore = the feature exists but is not for this user. It is for a different audience (enterprise when user is solo, technical when user is non-technical), or it duplicates something the user already has working. Be specific about why.

Watch = the feature is in preview, beta, or research release. The user should know it exists but should not change workflows yet. Include the expected GA date if the changelog gives one. If no date is given, write "No GA date stated."

## Output format

Use this exact structure. No extra sections. No preamble.

```
Weekly product update brief
[Today's date in YYYY-MM-DD]

## Priority context
[1 sentence echoing the user's PRIORITY_AREAS so the reader can confirm the brief was scoped right]

## Use this week (max 3)
1. [Product name] -- [Feature name] -- [1 sentence on the specific action to take this week, starting with a verb]
2. ...
3. ...

## Ignore (max 5)
1. [Product name] -- [Feature name] -- [1 sentence on why it does not apply to this user]
2. ...

## Watch (max 5)
1. [Product name] -- [Feature name] -- [Expected GA date or "No GA date stated"] -- [1 sentence on what would change for the user when it ships]
2. ...

## The 1 decision for this week
[1 sentence naming the single action the user will take today, before they close this brief]
```

## Rules

- Use the exact feature name as written in the changelog. If a changelog calls it "Cowork", write "Cowork", not "the new collaboration feature".
- Every Use item must start with a verb (Turn on, Replace, Switch, Move).
- No item can appear in more than 1 category.
- Maximum total length: 400 words.
- If a changelog has zero items that apply to the user, write "Nothing applicable this week" under the relevant section. Do not pad.
- Source URLs go at the bottom under a "Sources" section, 1 URL per line.

## Banned phrases

Do not use any of these:
- exciting new features
- best-in-class
- industry-leading
- next-generation
- cutting-edge
- game-changer
- supercharge
- unlock
- transform
- streamline

If the changelog uses any of these words about a feature, strip them and write only the concrete change.

## Self-check before responding

Confirm all 5:

1. Did I use the exact product and feature names from the changelogs?
2. Is every Use item a verb-led action the user can take today?
3. Did I avoid all banned phrases?
4. Is the brief under 400 words?
5. Does the "1 decision for this week" name a specific action, not a category?

If any answer is no, fix the brief before responding.

The race between Claude Code skills and Codex skills is a leading indicator of where agentic work compounds first. Both products are converging on the same shape from different starting points. Claude Code began as a coding agent and is generalizing into operator skills. Codex began as code completion and is adding the same skill surface. They are aiming at the same point from opposite directions. The operator who already has 5 working skills will get 10x more value from whichever product wins than the operator who treats them as chat windows. Write 1 skill a week for the rest of 2026 and you finish the year with 30 reusable workflows. That is the moat, and the model swap underneath does not change it.
