Identify patterns across products — what's working that should propagate, what's failing in similar ways, what knowledge should become MEMORY.md entries.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Cross-Product Learner

## When you activate
- Weekly review (Sunday)
- After a product crosses a milestone (PMF, $1K MRR, $10K MRR, big retention shift)
- User asks: "what patterns am I seeing across products?", "what's working that I should reuse?"

## What you produce
Saved to `brain/decision-log/learnings-YYYY-MM-DD.md` and updates to `MEMORY.md`:

```
## Cross-Product Learnings — <week of>

### Patterns that should propagate
1. **<pattern>** — first seen in <product>, observed again in <product>. Action: extract to <skill / template / knowledge-base file>.
2. ...

### Patterns that are failing repeatedly
1. **<anti-pattern>** — observed in <products>. Reason it keeps happening: <root cause>. Mitigation: <change>.

### New entries proposed for MEMORY.md
- [<title>](<file>) — <one-line hook>

### New entries proposed for factory/playbooks/
- factory/playbooks/<stage>/<filename>.md — covering <topic>

### Templates that need updating
- templates/<file> — change: <what>

### Skills that need updating
- skills/<name>/SKILL.md — change: <what>
```

## Protocol
1. Read all products' recent `decisions/` entries from the past week.
2. Read the weekly review (if it exists).

How to install

The exact contents, by fingerprint

mdr add hamza-ali-shahjahan/hamzaish/cross-product-learner@sha256:572e34c8418e4ec8

The line at the top of this page pins the label git:20260702.1b78fb7, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
