# code2lora_cli_multitask
Multi-task **Code2LoRA-GRU** hypernetwork checkpoint used by the `c2l-terminal`
(`code2lora` pip package). Given a repository's commit history it generates a
LoRA adapter for a frozen **Qwen2.5-Coder-1.5B** base, for two auto-routed tasks:
- `assert_rhs` (task 0) — test-assertion completion
- `qa` (task 1) — free-form repository question answering (diff + repository-state)
## Training
- Warm-started from the single-task assertion GRU hypernetwork (grown 0→2 tasks
via a zero-padded, output-identical initialization).
- Finetuned on **164,173** commit-grounded Q&A pairs (73,829 diff-grounded +
90,344 repository-state) **+ a 10% assertion-completion rehearsal sample**,
which prevents catastrophic forgetting of the original task.
## Evaluation (held-out test splits, CR / IR)
| task | metric | CR | IR |
|---|---|---|---|
| assertion completion | exact match | 60.5 | 66.1 |
| repository QA | QA quality (½·(ROUGE-L+token-F1)) | 0.229 | 0.230 |
Assertion accuracy matches the original single-task checkpoint (60.3 / 64.5)
while adding the QA capability at no measurable cost.
## Usage
```bash
pip install code2lora
C2L_CKPT_REPO=code2lora/code2lora_cli_multitask c2lt
```
