Devin Claude Bridge Progress

Updated: 2026-07-27

Baseline

• Fork version: 3.8.49.
• Starting branch: release/v3.8.49.
• Starting commit: ed7db3ee5f89a144b2d931d8605534522f83de30.
• Fixed runtime artifacts: Node 26.0.0, Claude Code 2.1.220, Devin CLI 3000.2.17.
• Existing devin-cli remains unchanged; the new path is the separate devin-cli-agentic provider.

Proved offline

• Focused unit and ACP suite: 27 tests passed.
• Anthropic wire suite: non-streaming JSON, SSE event order, tool_use, direct tool_result continuation, ACP error, and early process exit passed.
• Final container build completed with the pinned CLIs and the production OmniRoute build.
• Artifact inspection confirmed Node 26.0.0, Claude Code 2.1.220, and Devin CLI 3000.2.17 while the container had no network.
• Runtime isolation verifier passed in static and container checks.
• Real Claude Code offline E2E passed in 9 turns. It loaded CLAUDE.md, discovered the project skill and slash command, fired hooks, requested Skill, Bash, Read, and Edit, observed a failing test, corrected the edit, reran the test successfully, and returned the fixture's final success marker.
• Every offline inference action recorded by the ACP fixture names only devin-cli-agentic; provider termination returned an explicit error.

Evidence is generated under .sandbox/evidence and is intentionally ignored by Git.

Regression status

• Focused ESLint and typecheck:core passed; the final executor changes were rechecked with typecheck:core and the 27-test bridge suite.
• The complete npm run check reached the unit suite after lint, but the repository test runner did not terminate after quota-redis-store.test.ts: an ioredis client kept reconnecting to an unavailable local Redis endpoint. The runner was interrupted after repeated ECONNREFUSED events, so this command is not reported as passed.
• Documentation accuracy checks passed before this final status update and are rerun after it.
• The fresh image rebuild and dedicated Devin volume ownership retry passed.

Live Devin

Not passed. The official Devin login succeeded inside the dedicated volume, and model discovery selected swe-1-7-lightning. Authorized live runs established the following:

1. devin acp --agent-type summarizer is not a neutral inference backend. The CLI's own help identifies it as a no-tools summarizer, and its injected role caused future-action narration, summaries, and malformed tool envelopes instead of a reliable Claude Code tool loop.
2. The default devin acp agent can emit the required XML tool envelope in a minimal probe, but the full Claude Code request caused it to emit ACP tool_call events and attempt to own tool execution.
3. The adapter now rejects tool_call and tool_call_update with devin_internal_tool_execution (502). Two live requests were observed failing closed; a third in-flight request was aborted when the test was stopped to avoid automatic paid retries.
4. No three-scenario live pass exists. The live test must remain red until the official CLI exposes a neutral no-tools generation mode (without the summarizer role) or another supported Devin API provides equivalent raw model inference.

The offline contract still proves narrative -> single repair -> tool_use, and a second narrative now fails closed instead of being accepted as a successful final response.

Safety record

No host Claude executable, configuration, login, OAuth token, Keychain, or Anthropic API was used. The first pre-isolation unit attempt initialized the repository's default OmniRoute database at /Users/lucasisrael/.omniroute/storage.sqlite; it was not rolled back or touched again. All subsequent bridge commands set isolated database paths under .sandbox.

The final live attempts used only the dedicated Docker volumes. Claude Code ran only inside the non-root container; no host Claude configuration or credential path was mounted or read.
