Anthropic announced [Claude Science](https://www.anthropic.com/news/claude-science-ai-workbench) on June 30, 2026. It describes a research workbench that can use scientific tools, create artifacts, run specialist agents, and preserve an auditable history.

Auditability is stronger when represented as a graph of immutable inputs and derived artifacts rather than a chronological chat transcript.

``` php
question
  -> dataset@sha256
  -> environment@digest
  -> analysis-script@commit
  -> result-table@sha256
  -> figure@sha256
  -> manuscript-section@sha256
                 -> reviewer-finding
```

Each edge should name the operation and actor:

```
{
  "from": "analysis.py@4f2c1d",
  "to": "results.csv@sha256:...",
  "operation": "python analysis.py --seed 17",
  "environment": "oci:sha256:...",
  "actor": "agent:analysis-2",
  "started_at": "2026-07-14T08:12:00Z",
  "exit_code": 0
}
```

Assumptions:

| Failure | Detection | Recovery |
|---|---|---|
| dataset changes silently | digest mismatch | rerun descendants |
| package drift | environment mismatch | restore image or declare variance |
| figure edited manually | missing producing edge | attach source or mark manual |
| citation does not support claim | reviewer finding | revise claim and retain finding |
| parallel agents overwrite output | immutable IDs | create competing branches |

This graph is also how I think about coding agents. I use [MonkeyCode](https://monkeycode-ai.net/) and recommend evaluating its task workflow with commits, commands, and outputs captured as durable evidence. The hosted SaaS reduces setup; the [open-source self-hosted path](https://github.com/chaitin/MonkeyCode) offers more deployment control. That does not make it a scientific workbench, and I am not claiming a Claude Science integration. The useful shared principle is that long-running work should leave verifiable artifacts.

Disclosure: I'm a MonkeyCode user sharing my own experience, not affiliated with the project.

The verification path is straightforward: delete chat history from a disposable run and ask whether another person can reproduce the figure from the graph. If not, the system preserved conversation, not provenance.
