# Analyst Bootstrap Implementation Plan

> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.

**Goal:** Add `da analyst setup` command that onboards analysts to a remote Agnes instance — connects, downloads data, initializes local DuckDB, generates CLAUDE.md.

**Architecture:** New top-level Typer command `da analyst` with `setup` subcommand. Uses existing `cli/client.py` HTTP helpers. Generates CLAUDE.md from template with instance-specific placeholders.

**Tech Stack:** Typer, httpx (via cli/client.py), DuckDB, Rich (progress bars), Jinja2-style string substitution

**Spec:** `docs/superpowers/specs/2026-04-10-porting-internal-features-design.md` — Section 2

**Depends on:** Business Metrics plan (Task 5 — metrics API must exist for Step 4)

---

### Task 1: CLAUDE.md Template

**Files:**
- Create: `config/claude_md_template.txt`

- [ ] **Step 1: Create the template file**

Create `config/claude_md_template.txt`:

```
# {instance_name} — AI Data Analyst

This workspace is connected to {server_url}.

## Rules
- Before computing any business metric: run `da metrics show <category>/<name>`
- For current schema: read `data/metadata/schema.json`
- Do not use DESCRIBE/SHOW COLUMNS — read metadata files instead
- Save work output to `user/artifacts/`
- Sync data regularly with `da sync`

## Metrics Workflow
1. `da metrics list` — find the relevant metric
2. `da metrics show revenue/mrr` — read SQL and business rules
3. Use the canonical SQL from the metric definition, adapt to the question
4. Never invent metric calculations — always check existing definitions first

## Data Sync
- `da sync` — download current data from server
- `da sync --docs-only` — just metadata and metrics (fast refresh)
- `da sync --upload-only` — upload sessions and local notes to server
- Data on the server refreshes every {sync_interval}

## Directory Structure
- `data/` — read-only data downloaded from server
  - `data/parquet/` — table data in Parquet format
  - `data/duckdb/` — local analytics DuckDB database
  - `data/metadata/` — profiles, schema, metrics cache
- `user/` — your workspace (persistent across syncs)
  - `user/artifacts/` — analysis outputs, reports, charts
  - `user/sessions/` — Claude Code session logs
- `.claude/CLAUDE.local.md` — your personal notes (never overwritten, uploaded on sync)
```

- [ ] **Step 2: Commit**

```bash
git add config/claude_md_template.txt
git commit -m "feat: add CLAUDE.md template for analyst bootstrap"
```

---

### Task 2: `da analyst setup` — Core Command

**Files:**
- Create: `cli/commands/analyst.py`
- Modify: `cli/main.py` (register analyst_app)
- Test: `tests/test_cli.py` (help test)
- Test: `tests/test_analyst_bootstrap.py`

- [ ] **Step 1: Write failing tests**

Add to `tests/test_cli.py` in `TestCLIHelp`:

```python
    def test_analyst_help(self):
        result = runner.invoke(app, ["analyst", "--help"])
        assert result.exit_code == 0
        assert "setup" in result.output

### Task 3: Returning-Session Detection

**Files:**
- Modify: `cli/commands/analyst.py` (add `da analyst status` command)
- Test: `tests/test_analyst_bootstrap.py`

- [ ] **Step 1: Write failing test**

Add to `tests/test_analyst_bootstrap.py`:

```python

        import json

        result = _check_data_freshness(tmp_workspace)
        assert result == "missing"
```

- [ ] **Step 2: Run test to verify it fails**

Run: `pytest tests/test_analyst_bootstrap.py::TestReturningSession -v`
Expected: FAIL — `_check_data_freshness` not found

- [ ] **Step 3: Implement freshness check and status command**

Add to `cli/commands/analyst.py`:

```python
@analyst_app.command("status")
def status():
    """Check workspace status and data freshness."""
    workspace = Path.cwd()

    claude_md = workspace / "CLAUDE.md"

        from datetime import datetime, timezone, timedelta
        last_sync = datetime.fromisoformat(last_sync_str)

        age = datetime.now(timezone.utc) - last_sync
        if age > timedelta(hours=24):
            return "stale"
        return "fresh"
    except Exception:
        return "missing"
```

Also update `_download_metadata` to write `last_sync.json`:

At the end of the `_download_metadata` function, add:

```python
    # Record sync timestamp
    from datetime import datetime, timezone
    sync_record = {"last_sync": datetime.now(timezone.utc).isoformat(), "server_url": server_url}
    (metadata_dir / "last_sync.json").write_text(json.dumps(sync_record))
```

- [ ] **Step 4: Run tests to verify they pass**

Run: `pytest tests/test_analyst_bootstrap.py -v`
Expected: ALL PASS

- [ ] **Step 5: Commit**

```bash
git add cli/commands/analyst.py tests/test_analyst_bootstrap.py
git commit -m "feat: add da analyst status and returning-session freshness check"
```

### Task 4: Final Integration

- [ ] **Step 1: Run full test suite**

Run: `pytest tests/ -v --timeout=60`
Expected: ALL PASS

- [ ] **Step 2: Commit if any fixes needed**

```bash
git add -A
git commit -m "fix: address analyst bootstrap integration issues"
