Open-source SDLC agent harness says it beats cold Claude Code on large repos

An open-source project called AutoDev Studio claims to outperform a cold Claude Code run on large repositories by paying the repo-localization cost once and reusing it across tasks.
What it does
- Ingests a Git repo and builds a durable knowledge base from static analysis plus a local embedding index.
- Runs a multi-agent SDLC pipeline: PM agent for clarification and tickets, Dev agent for code changes, QA/testing, and a separate reviewer model.
- Opens a real PR and tracks token and dollar costs per task and per agent.
Results reported
- On textual (82k LOC) and rich (35k LOC), the tuned pipeline beat a cold claude -p on 6/6 well-localized tasks.
- Savings ranged from 7% to 75%.
- In one bug, the cold agent spent $6.83 and 207 turns locating the issue, while the pipeline fixed it for about $1.70.
Limits and caveats
- On tiny, trivially greppable edits, the fixed five-stage overhead can cost more than it saves.
- On one cross-cutting bug, it produced a cheaper but narrower fix than the baseline.
- The stack is provider-agnostic, supports Anthropic, Claude Code CLI, and OpenAI-compatible endpoints, and can run with a free local embedding model.
