Govern what happens to a confirmed finding once it is reported and you are not going to publish it — the difference between disclosing an instance, a mechanism, and a hunting method; the patch-diffing window that leaks the class whether or not you write a word; custody of the PoC and of any data you touched confirming it; and a written decision with a revisit trigger instead of an undocumented default. Use whenever a finding is confirmed and the question turns to who is told what, whenever a…

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

# Finding Custody

A confirmed finding is not finished when the vendor patches it. It is an asset
you are still holding: a working technique, an understanding of a class, and
usually a PoC that runs. Most methodologies end at "reported". Everything after
that point — what you say, what you keep, what you delete, and what would make
you revisit — is governed by nothing, which is why it is governed by habit.

Two claims this skill is built on:

> **Silence has operational requirements.** Deciding not to publish is not the
> zero-cost option; it is a custody obligation with a start date and no
> automatic end.

> **The patch is a disclosure you did not write.** A fix describes the bug,
> authored by the people who understand it best, shipped publicly. Whatever the
> patch reveals is revealed on the vendor's schedule, not yours.

This skill takes no position on whether to publish. It exists so that the
decision is made once, deliberately, with a written reason and a condition that
reopens it — rather than defaulting to silence and then never looking again.

Composes with the library:

- **remediation-driven-reporting** — the sibling: how the report gets the class

How to install

The exact contents, by fingerprint
mdr add annatchijova/skills/finding-custody@sha256:d01bc65db3e56b71

The line at the top of this page pins the label git:20260822.0212fed, 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.
