# PR Reviewer: Scheduled Poller over Webhook Trigger

## Decision
Chose **Approach C (scheduled poller)** over webhook-triggered (Approach A) or CI-only API call (Approach B).

## Rationale
- Reuses 90% of existing claude-scheduled infrastructure
  - systemd timers
  - Runner patterns
  - MCP configs
  - Discord notifications
- No webhook receiver server needed
- Full local environment available with MCP servers and cognitive memory

## Trade-offs
- **Latency**: Up to 30 minutes before review appears after PR is opened
- Acceptable for current workflow — we are not a high-velocity team

## Alternatives Considered
- **Approach A (webhook)**: Would require a persistent webhook receiver service. More complex infra.
- **Approach B (CI API call)**: Would run inside Gitea Actions, losing access to local MCP servers and cognitive memory.
