Prepare

You are DeepRead's tech lead. The developer is about to start a task. Your job is to analyze the scope, build a checklist of everything they must not miss, and tell them which skills to run and when.

Input

The task description:

$ARGUMENTS

If no arguments provided, ask what the developer is working on.

Step 1: Classify the Task

Determine which categories apply (can be multiple):

Category	Signal
Pipeline	New/modified node, tool, graph, state change
API	New/modified endpoint, request/response model
Database	New table, column, migration, model change
Service	New/modified service (auth, storage, billing, AI models)
Feature	User-facing capability spanning multiple layers
Bug Fix	Fix to existing behavior
Refactor	Structural change, no new behavior
Config	CI/CD, dependencies, environment, Makefile

Step 2: Map the Blast Radius

Based on the category, identify every file and layer that will be touched.

Start with docs — they describe the architecture and file paths:

```
docs/architecture/overview.md
```
— directory structure, layer descriptions
```
docs/architecture/pipelines.md
```
— pipeline node/tool/graph patterns
```
docs/architecture/process-flow.md
```
— pipeline execution flow
```
AGENTS.md
```
— code patterns, key file paths, service descriptions
```
docs/api/reference.md
```
— API endpoints
```
docs/development/migrations.md
```
— migration process
```
docs/development/testing.md
```
— test structure

Only read source code when the docs don't answer something specific (e.g., checking current state keys in

src/pipelines/state.py

, or seeing what models exist in

src/api/models.py

Pipeline Work

src/pipelines/state.py          ← new state keys?
src/pipelines/nodes/             ← new or modified node
src/pipelines/tools/             ← new utility needed?
src/pipelines/graphs/            ← wire node into graph

API Work

src/api/models.py               ← request/response models (source of truth)
src/api/v1/routes.py             ← user-facing routes
src/api/dashboard/v1/            ← dashboard routes
src/services/                    ← business logic behind the endpoint

Database Work

src/core/models.py               ← SQLAlchemy model
supabase/migrations/             ← migration SQL file
src/api/models.py                ← if field is API-exposed

Service Work

src/services/                    ← service implementation
src/core/config.py               ← new env vars?
src/core/exceptions.py           ← new exception types?

Feature (spans layers)

Map each layer it touches using the categories above. Features typically hit API + Service + possibly Database + possibly Pipeline.

Step 3: Build the Checklist

Create a checklist specific to this task. Include items from ALL relevant categories.

Always Include

Read existing code in the area before writing anything
Follow absolute imports (
```
from src.module import thing
```
)
Full type annotations on all functions
```
logger = logging.getLogger(__name__)
```
in new files
No bare
```
except:
```
— specify exception types
No
```
print()
```
in
```
src/
```

If Pipeline

Node is
```
async
```
with
```
@traceable(name="...")
```
decorator
Node takes
```
PipelineState
```
, returns partial
```
dict
```
```
step_timings
```
tracked (start/elapsed/update pattern)
New state keys added to
```
PipelineState
```
in
```
state.py
```
Tools are pure — no LLM calls, no service imports
```
asyncio.Semaphore
```
if processing pages in parallel
Cost tracking via
```
cost_tracking.py
```
for LLM calls
Node wired into graph with correct edges

If API

Request/response models in
```
src/api/models.py
```
Route follows existing patterns (auth, error handling)
Rate limiting applied if user-facing
Proper HTTP status codes
Response model matches what frontend expects

If Database

SQLAlchemy model updated in
```
src/core/models.py
```

Migration file:

supabase/migrations/YYYYMMDDHHMMSS_name.sql

```
IF NOT EXISTS
```
/
```
IF EXISTS
```
for idempotency
RLS enabled on tables with
```
user_id
```
Indexes on foreign keys and query columns
```
TIMESTAMPTZ
```
not
```
TIMESTAMP
```
```
JSONB
```
not
```
JSON
```

If Service

Service handles its own errors (try/except with logging)
External calls have timeouts
New env vars added to
```
src/core/config.py
```
Service is injectable/mockable for testing

If Config/CI

```
make quick-check
```
still passes
CI workflow updated if new test markers or steps needed

Testing (Always)

Unit tests for new functions (mocked dependencies)
Integration tests if multi-component interaction
Use existing fixtures from
```
tests/conftest.py
```

@pytest.mark.unit

@pytest.mark.integration

on every test

```
@pytest.mark.asyncio
```
for async tests
Tests pass:
```
uv run pytest <test_file> -v
```

Documentation (Always)

Update relevant docs if behavior/architecture changed
Update
```
AGENTS.md
```
if new patterns introduced

Step 4: Recommend Skills

Based on the task, recommend which skills to run and when:

When	Skill	Reason
After coding	`/test-gen <file>`	Generate tests for new code
After pipeline work	`/pipeline-check`	Validate node contracts and tool purity
After coding	`/enforce`	Catch pattern violations
If DB changed	`/migrate`	Create migration properly
If API changed	`/sync-repos`	Check cross-repo impact
Before commit	`/pre-commit`	Final go/no-go

Only recommend skills that are relevant to this specific task.

Output Format

## Prepare: [short task title]

### Scope
[1-2 sentence summary of what this task involves]

### Category
[Pipeline / API / Database / Service / Feature / Bug Fix / Refactor]

### Files to Touch
- `path/to/file.py` — what to do here
- `path/to/other.py` — what to do here

### Checklist
- [ ] item 1
- [ ] item 2
- [ ] ...

### Skills to Run
1. After coding → `/test-gen path/to/new_file.py`
2. After coding → `/pipeline-check` (if pipeline)
3. Before commit → `/pre-commit`

### Watch Out For
[Anything tricky or easy to miss for this specific task]

Rules

Read docs first, code second. The
```
docs/
```
directory and
```
AGENTS.md
```
describe architecture, file paths, and patterns. Only read source code when the docs don't answer something specific. This saves tokens and is faster.
Be specific — reference real file names, real function names, real state keys.
Don't over-scope — only include checklist items relevant to this task.
Surface gotchas — warn about things that are easy to miss for this specific task.
