# Startup Artifacts

## Required Reads

- `AGENTS.md`
- `.ai/environment/tools.ai.yaml`
- `ai-plan/public/todos/`
- `ai-plan/public/traces/`

## AI-Plan Selection Heuristics

- Match the user's wording against public todo and trace file names first.
- Prefer the newest matching trace when several candidates describe the same feature area.
- If one file records a clearer recovery point than a newer but vague file, prefer the clearer recovery point.
- If a matching `ai-plan/private/<branch-or-worktree>/` directory exists, use it only as private context for the current worktree.

## Complexity Defaults

- `simple`: keep everything local, no subagent
- `medium`: keep design local, optionally use one `explorer` for parallel read-only discovery
- `complex`: keep architecture and integration local, delegate only bounded non-blocking subtasks

## Model Defaults

- `explorer`: `gpt-5.1-codex-mini`
- `worker`: `gpt-5.4`

## Startup Summary Template

Use a short update before execution:

`Read AGENTS.md, the environment inventory, and the relevant public ai-plan artifacts. This looks like a <task-state> <complexity> task. I will <delegate-or-not> and start with <first-step>.`
