delta-briefing
Make a recurring brief report what changed since the last edition instead of restating everything. Use when a weekly or monthly report keeps repeating itself, when setting up a scheduled monitor or digest, or when asked to make a recurring update delta-aware. Produces a changes-first brief plus the state record the next run will diff against.

Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# Delta Briefing Skill The failure mode of every recurring report is that edition 6 reads like edition 5. This skill structures a recurring brief around the *delta*: read the last edition's state, diff the world against it, lead with what changed, and save state for the next run. ## What This Skill Produces - A **changes-first brief**: new / changed / resolved / unchanged-but-watched - A **state record** (compact, machine-readable) that the next edition diffs against - An explicit **"nothing changed" edition format** — short, honest, and still useful ## Required Inputs Ask for (if not already provided): - **The brief's subject and audience** (competitive landscape, product metrics, account health…) - **The previous edition or state record** — if none exists, this run is the baseline: say so in the output and produce the first state record - **Current sources** for this cycle - **Where state lives** between runs (a file next to the brief, a Brain folder — see BRAIN.md if using this library's memory) ## Delta Method 1. **Load last state.** Parse the previous state record (or previous edition if that's all there is). List the items it tracked and their status. 2. **Re-observe.** Gathe

What does the delta-briefing skill do?
Make a recurring brief report what changed since the last edition instead of restating everything. Use when a weekly or monthly report keeps repeating itself, when setting up a scheduled monitor or digest, or when asked to make a recurring update delta-aware.

How do I install it?
Run `npx skills add mohitagw15856/pm-claude-skills --skill delta-briefing --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From mohitagw15856/pm-claude-skills, a repository with 1,255 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
