Project Context Loader

Load project conventions and generate session context on demand.

---

When to Use

Before: /run, code generation, refactoring, test writing. Skip: Simple questions (no code), when session-context.toon already loaded.

---

Loading Process

1. Check Cache

If .claude/session-context.toon exists and is recent (< 1 hour), use it.

2. Generate (If Missing)

Scan codebase for: file naming, import style, export pattern, error handling, testing framework, styling approach. Write to .claude/session-context.toon.

3. Load Project Config

From .claude/project-contexts/[project]/:

File	When
project-config.yaml	Always
conventions.md	Always
rules.md	Always
repo-map.md	First task
file-registry.yaml	When modifying code
architecture.md	Architecture decisions

4. Smart Loading

loading_strategy[4]{scenario,files_to_load}:
  Simple question,session-context.toon only
  Bug fix / small change,"session-context.toon + conventions.md + file-registry.yaml"
  New feature / refactor,All 7 files
  Architecture decision,"session-context.toon + architecture.md + repo-map.md"

Token budget: Simple ~200, Bug fix ~800, Full ~2000, Architecture ~1000.
