# Use Claude Code and other harnesses safely: synthetic exercise worksheet

Curriculum reviewed: 2026-10-25. Use public or synthetic data only.
Do not include client evidence, credentials, private identifiers or raw receipts.

## Goal
A synthetic prompt/review transcript annotated with consent, evidence and disclosure decisions.

## Outcomes
- Discover installed skills through the correct harness adapter
- Give bounded tasks with evidence and human decision points
- Review source-read and deployment consent before effect
- Distinguish local authoring from preview Hosted read-only MCP

## Synthetic case
Describe a Sales report built from order headers and order lines. State which grain you intend and which independently established expectation you would compare.

## Review each lesson
### 1. Install and discover the right skills
Use the documented plugin namespace or a deterministic harness adapter.
Expected output: a written explanation naming the observation, its scope and its limits.
Your notes:

### 2. Give the agent a bounded task
Request a draft, plan or explanation with references and a stopping point.
Expected output: a written explanation naming the observation, its scope and its limits.
Your notes:

### 3. Review before effect
Inspect source-read and digest-bound deployment requests before authorising an action.
Expected output: a written explanation naming the observation, its scope and its limits.
Your notes:

### 4. Keep values in the right boundary
Separate local evidence, Fabric, agent-provider exposure and Hosted metadata.
Expected output: a written explanation naming the observation, its scope and its limits.
Your notes:

### 5. Resume from evidence
Use project status and receipt history without confusing the two Spine workflows.
Expected output: a written explanation naming the observation, its scope and its limits.
Your notes:

### 6. Ask Hosted about status
Rehearse authorised read-only MCP questions with honest preview and certification limits.
Expected output: a written explanation naming the observation, its scope and its limits.
Your notes:

## Failure case
Generated definitions exist but a required execution observation is missing. Explain why qualification cannot pass and name the next required observation. Do not fabricate a receipt or change a frozen expectation.

## Evidence table
| Claim | Expected observation | Available evidence | Missing/stale | Next owner/action |
| --- | --- | --- | --- | --- |
| | | | | |

## Limitations
This worksheet is a completion check, not live qualification, business acceptance or a professional award. Pro assessment and certification policy remain planned. Keep optional live results in customer-controlled custody.
