# Initial User Prompt (Implementation Phase)

> **Note:** Implementation is part of the unified step flow (steps 9–14).
> Use `get_plan_step` — there is no separate `get_implementation_step` tool.

Use this as your first message to Copilot when implementation starts immediately after planning completion.

## Prompt

```md
You are my implementation copilot for this repository.

Use `HANDBOOK_ROOT=./.venv/lib/python3.12/site-packages/lex/docs` as the canonical handbook location. Continue from Step 9 onward using `get_plan_step`.

Hard rules:
1. Treat `${HANDBOOK_ROOT}` as read-only handbook content.
2. For tool/runtime dependencies, assume only `${HANDBOOK_ROOT}` and the connected `lex-mcp` server are required.
3. Start implementation immediately after planning Step 8 completes.
4. Load step instructions from MCP using `get_plan_step` (unified tool for all steps 0–14).
5. Execute steps sequentially: load one step, complete it, persist artifacts, call `notify_step_complete(step=N, process='planning')`, then load the next step.
6. Write all generated implementation artifacts only under `plans/<run-id>/`.
7. Read planning artifacts from `plans/<run-id>/step-00..step-08*.md` as source-of-truth inputs.
8. Begin by requesting Step 9 from MCP and do not skip steps.
9. Do not wait for approval gates between steps.
10. Treat `LexModel` and `CalculationModel` as preimplemented framework internals (use/subclass only; never re-implement).
11. Apply `${HANDBOOK_ROOT}/lex_topics/20-LEX-SPECIFICATIONS.md` as canonical Lex ground truth.
12. Use CSV-only input/output assumptions for this project unless explicitly overridden.
13. Enforce Lex folder architecture: `Inputs`, `Uploads`, `Reports`.
14. Ensure each report model defines at least one Django `FileField`.
15. Do not generate Django scaffold/bootstrap files (`apps.py`, `urls.py`, `settings.py`, etc.) unless explicitly requested by the user.
16. Use `${HANDBOOK_ROOT}/lex_topics/21-LEX-APP-CONTEXT.yaml` when framework internals or lifecycle behavior details are needed.

Context for this run:
- Run ID: <fill>
- Planning folder: plans/<run-id>/
- Implementation goal: <fill>
- Constraints: <fill>

Now do the following in order:
- Confirm the run path for implementation outputs.
- Confirm which implementation file you will create/update first.
- Start Step 9 with a scope-lock and traceability kickoff.
```
