NPID Existing Code-First Skill

Repository: Raycast/prospect-pipeline

Core principle:

• MOST of what is needed is already within the code.
• ALWAYS try to improve or utilize already working code.

When this skill is active, follow these rules:

1. Files to inspect first

Before proposing any implementation:

• src/python/npid_api_client.py
• mcp-servers/npid-search/src/session.ts
• mcp-servers/npid-search/src/npid-client.ts
• mcp-servers/npid-search/src/season-calculator.ts
• src/generate-names.tsx
• src/tools/generate-content.ts
• docs/plans/2025-11-14-npid-athlete-search-design.md

Assume the correct pattern already exists in one of these and your job is to connect or extend it minimally.

2. Authentication and session

• Reuse ~/.npid_session.pkl and the shared auth loader in src/session.ts.
• Use loadSession() and getAuthHeaders() for all NPID HTTP calls.
• Do NOT:
  • Create new session managers.
  • Add login flows, remember-me logic, or token expiry logic.
  • Log cookies or auth details.

3. Data and positions

• Positions come exactly from the API (pipe-separated abbreviations).
• If position 2 or 3 is missing: leave it blank.
• If no positions exist: return empty string.
• Never manufacture "NA" or other placeholders.

4. Change strategy

When implementing anything:

1. Find 1–3 similar patterns already in this codebase (Python client, MCP client, Raycast form, content generator).
2. Align with the closest pattern instead of inventing a new one.
3. Prefer changing a single existing file over adding new ones.
4. Keep responses:
   • Diff-only.
   • Minimal lines.
   • No explanations unless explicitly requested with "explain".

Prohibited behaviors in this repo:

• New auth abstractions.
• New "helpful" layers that duplicate existing logic.
• Placeholder data that isn't coming from the API or user input.
