## Which one, for what

### DeepSeek Harness (dsh) (D)

Good for: Developers who use DeepSeek models and want a scriptable harness with ACP, a JSON event stream and a Python SDK.

Ahead on:
- Reliability, 33 against 13
- Payments & pricing, 60 against 30
- Maintenance & community, 71 against 18
- Transparency & trust, 50 against 44

Also in its favour:
- Free to start without a card
- Open source

Watch for: By default each request to DeepSeek's official API carries the session log, including message text, tool arguments and results, up to 8 MiB a request

### Jules (E)

Good for: A person or pipeline that wants to hand scoped GitHub tasks to a cloud agent and collect a pull request or a patch, or run a repoless job in a disposable VM.

Ahead on:
- Security & auth, 57 against 40

Also in its favour:
- Runs on your own machine
- No incidents deducted, where DeepSeek Harness (dsh) loses 6 points for them

Watch for: The REST API has been v1alpha since 3 October 2025 and the docs say specifications and API keys may change

## Verdicts

**DeepSeek Harness (dsh).** Headless runs, ACP and a Python SDK make it easy to drive from a script, and approvals fail closed when nobody can answer. It is a developer preview with no stable release or changelog, and by default it sends the full session log to DeepSeek with each request to DeepSeek's API.

**Jules.** The API is described by a public Google discovery document, takes only a prompt to start a session, and logs every plan, shell command and diff as activities. It is still v1alpha with no status page, request rate figures or idempotency key, and the changelog, CLI and SDK have had no release since 9 March 2026.

## Before you call either

### DeepSeek Harness (dsh)

1. Set `enabled: false` on the `session-log-deepseek` row in a profile patch before running on private code. Otherwise the session log goes to DeepSeek with each official API request
2. Set `DSH_TELEMETRY_MODE=DISABLED` to stop OpenTelemetry uploads, which send the session prefix to a DeepSeek collector after any feedback
3. Treat exit code 1 and the `turn_end` reason as failure. A `--json` stream can end with a `final` event for a failed run
4. Run in a disposable container or VM. The sandbox doesn't confine reads or network, and SAFETY.md says the project has had no security audit
5. Pin the version. npm `latest` (0.2.0-rc.2) and `next` (0.2.1-rc.2) differ, DeepSeek's changelog asks for 0.2.1-rc.1 or later, and the README warns of breaking changes

### Jules

1. Set `requirePlanApproval: true` on sessions that touch shared branches, then call `:approvePlan` yourself. API sessions otherwise run their plan without review
2. Session creation has no request ID. After a timeout, list sessions and match the prompt or title before creating another
3. Poll activities with a `create_time` filter and cache them. Activities never change once written
4. Read the request fields from the discovery document at https://jules.googleapis.com/$discovery/rest?version=v1alpha. The field tables on jules.google render empty
5. Budget against the daily task quota of 15, 100 or 300 by plan. New sessions are refused until the rolling 24 hours reset
