# Agents, approvals and the log

The DCS module's agent tools, how every change an agent makes is approved by a person, and what the module logs.

**Verification state:** modelled. The tools are tested through the Editor's tools service with real text models and the real edit service on Linux; **they have not been used by a language model in the running Editor.** On the real export the largest result (the largest sequence) is about 190,000 characters, with expressions over 2,000 characters cut.

## The tools

The tools exist only while the DCS environment runs. Each is tagged read-only or state-changing.

| Tool | Effect | What it does |
|---|---|---|
| `neuralInverse_dcs_listExports` | read-only | Lists the workspace's exports |
| `neuralInverse_dcs_summary` | read-only | Summarises an export |
| `neuralInverse_dcs_findModules` | read-only | Finds modules |
| `neuralInverse_dcs_module` | read-only | Reads a module with its parameters and the paths that name it |
| `neuralInverse_dcs_alarms` | read-only | Lists alarms |
| `neuralInverse_dcs_checks` | read-only | The module's checks of an export |
| `neuralInverse_dcs_sequences`, `neuralInverse_dcs_sequence` | read-only | Lists sequences; reads one |
| `neuralInverse_dcs_impact` | read-only | The impact of a library change |
| `neuralInverse_dcs_setAlarm` | changes an export | An alarm's priority, enabled or suppression timeout |
| `neuralInverse_dcs_setParameter` | changes an export | An instance's overridden parameter |

- They read the export as the editor holds it, unsaved changes included.
- A path must name a `.fhx` inside the workspace.
- Results are marked as data read from the export, not instructions, and are capped (lists at 500 items, strings at 2,000 characters, the whole result at 200,000).
- A change is made through the same edit service as the tables: one change, one Undo, logged, never saved by the tool.

No tool imports into DeltaV, runs the DeltaV export, downloads to a controller or writes to a running plant.

## Every change is approved by a person

Every change an agent makes asks the engineer every time: its own **Apply Change** and **Cancel** buttons in the chat, and a dialog when the chat approved the call without asking (auto approval, Autopilot, a stored approval or a hook). No edit lands without a person's click, and no tool asks for pre-approval. The confirmation shows names and values as plain text.

## The log

Every edit, the save guard's decisions and every DeltaV export run are logged to **Output > DCS**, the Editor window's output channel. The module keeps no other audit record and does not apply the organisation's governance policy to its actions. See [Neural Inverse Govern](https://neuralinverse.com/docs/govern/).
