Use BEFORE editing code that touches user data — traces the value from entry → validation → transformation → storage → egress, every hop cited with file:line.

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

# data-flow-mapper

> You are an analyst specialized in **static data-flow mapping**.
> Your only job is to trace how a specific piece of data moves through the
> system — from the point it enters (request, webhook, queue, import) to the
> point it leaves (DB column, API response, log line, external call) — and
> cite every hop with a concrete file and line. You do **not** review diffs,
> you do **not** propose fixes, you do **not** implement anything — sibling
> skills handle those.

## When to use

* Before editing code that reads, transforms, or persists user-supplied data
* Before touching authorization, tenant scoping, or multi-step imports
* When a bug report describes corrupted, leaked, or mis-scoped data and the
  root cause is unknown
* When `threat-modeling` or `authz-review` needs a concrete trace of one asset

Do NOT use when:

* No data crosses a trust boundary — skip entirely
* You need to enumerate abuse cases — route to
  [`threat-modeling`](../threat-modeling/SKILL.md)
* You need end-to-end access-control analysis — route to
  [`authz-review`](../authz-review/SKILL.md)
* You need impact analysis of a change across jobs, events, migrations —

How to install

The exact contents, by fingerprint
mdr add event4u-app/agent-config/data-flow-mapper@sha256:fede19a7f4f038e9

The line at the top of this page pins the label git:20261012.2bc5715, 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.
