## Summary        {#summary}
`Osysharp.Privacy.Agents` makes every piece of agent work part of what a person can see, have kept out of use, or have erased — and keeps none of it past its time.

Two things are kept for different times: what the work said, a month by default; and that it happened, seven months by default. An erasure takes the words and keeps the chain, so the record still proves it was not changed.

|---|---|
| Package | `Osysharp.Privacy.Agents`, version 1.1.0 |
| You add it with | Nothing. It arrives by itself in an app that uses [[agent-kit-privacy\|Privacy]] and [[agent-kit-agents\|Agents]]; `osy lock` says so. `without Osysharp.Privacy.Agents;` in the manifest keeps it out. |
| It sits on | [[agent-kit-agents\|Agents]], [[agent-kit-privacy\|Privacy]] |
| It also uses | `Identity` — parts of the platform's own library |
| Its own test app | A town library whose desk is an AI agent — `kits/privacy-agents/tests` |

## Description    {#description}

### What do you get without writing anything?   {#free}
- Work done for a signed-in person is found by their account, with nothing written.
- After an erasure, `VerifyTrace` still answers intact.
- Corrections and instructions about a person are covered too.

### When do you need it?   {#when}
Privacy and Agents together. It arrives by itself. You write one line for work *about* somebody: `MarkAgentWorkAbout`.

### What does it expose?   {#exposes}
The tables below are generated from the kit itself, not written by hand: `osy kits Osysharp.Privacy.Agents --surface` lists each of
them with the code of the kit's own test app that uses it, and the tests that show it working.

**Settings** — one line in the app, each field with a default.

| You write | It says |
|---|---|
| `app.AgentsPrivacy = new AgentsPrivacySetup { KeepContentMonths, KeepRecordMonths, KeepCorrectionsMonths }` | How long this app keeps what its agents did. |

**Functions you call**, those its own tests show most first.

| Function | What it does | Tests that show it |
|---|---|---|
| `MarkAgentWorkAbout(Guid task, DataSubject subject)` | Say whose data a piece of an agent's work is: `task` — the id an `AgentOutcome` carries — is about `subject`. | 7 |
| `AgentWorkOf(DataSubject s)` | The work an agent did for or about a person — the top piece of each, once: work their account asked for or was given for, and work the app marked as about them (by the account, an address or a nu… | 7 |
