## Major Structural Changes

### Added: Skills Module (`g3-core/src/skills/`)

New module implementing Agent Skills specification:

```
g3-core/src/skills/
├── mod.rs        # Module root, re-exports
├── parser.rs     # SKILL.md YAML frontmatter parser
├── discovery.rs  # Skill directory scanning
├── prompt.rs     # XML prompt generation
├── embedded.rs   # Compile-time embedded skills
└── extraction.rs # Script extraction to .g3/bin/
```

**Internal dependency flow**:
```
mod.rs
  ├── parser.rs (Skill struct)
  ├── discovery.rs → parser.rs, embedded.rs
  ├── prompt.rs → parser.rs
  ├── embedded.rs (standalone)
  └── extraction.rs → embedded.rs
```

### Removed: Research Tool (hardcoded)

- `g3-core/src/pending_research.rs` (540 lines deleted)
- `g3-core/src/tools/research.rs` (710 lines deleted)

### Added: Research Skill (external)

- `skills/research/SKILL.md` (144 lines)
- `skills/research/g3-research` (338 lines, bash script)

Research functionality moved from hardcoded tool to external skill.

### Modified: SDLC Pipeline

- State storage moved from `analysis/sdlc/` to `.g3/sdlc/`
- Added merge-to-main on successful completion
- Worktree preserved on failure for debugging

## Extraction Limitations

- Dynamic imports not detected (none expected in Rust)
- Test-only dependencies not distinguished from production
- Conditional compilation (`#[cfg(...)]`) not analyzed
- External crate dependencies (from crates.io) not enumerated
