✅ Pipeline Test Result: BHAA-1339 Hello World

Date: 2026-08-03 09:24 UTC Status: PASSED (with one minor gap)

What Happened

The Sandbox Dev agent was given BHAA-1339: “Create hello.py with a simple print statement and test it.”

The agent successfully:

  1. ✅ Read the task from Paperclip
  2. ✅ Created src/hello.py with say_hello() function
  3. ✅ Created tests/test_hello.py with pytest capsys test
  4. ✅ Ran tests — 1 passed in 0.01s
  5. ✅ Committed to git — 0860257 “feat: add hello world module with tests”
  6. ✅ Posted comment in Paperclip with details and commit hash
  7. ✅ Marked issue as done
  8. ⚠️ Did NOT push to remote — committed locally but didn’t git push

Cost

  • Model: openrouter/deepseek/deepseek-v4-flash-0731
  • Output tokens: 3,201
  • Cost: $0.01
  • Duration: ~2 minutes (queued to done)

Issues Found & Fixed During Testing

Issue 1: Stale OpenCode Binary (ROOT CAUSE of all failures)

Paperclip’s systemd service had /root/.opencode/bin first in PATH, which contained OpenCode v1.15.10 (the old binary). The new v1.18.11 was installed via npm at a different path. The old binary couldn’t resolve the deepseek model.

Fix: Symlinked /root/.opencode/bin/opencode → /root/.nvm/versions/node/v24.14.1/bin/opencode (v1.18.11)

Issue 2: Paperclip Workspace Resolution

Paperclip resolved to agent_home instead of the project workspace. Even with project_workspaces entries and adapter_config.cwd set, Paperclip used its internal workspace directory.

Fix: Symlinked the agent_home directory to the actual git repo: /root/.paperclip/instances/default/workspaces/{agent_id} → /root/repos/sandbox

Issue 3: Agent Didn’t Push

The AGENTS.md says “NEVER mark work as done without pushing to remote” but the agent committed locally and didn’t push. The code WAS pushed after the fact by J.A.R.V.I.S., and it was already there (possibly Paperclip’s workspace sync handled it).

Fix needed: Reinforce push requirement in agent instructions.

Verification Chain (All Passed)

CheckResult
Code exists in git✅ commit 0860257
Tests pass✅ 1 passed

Pushed to remote⚠️ Pushed after-the-fact (agent committed but didn’t push)

Pipeline Flow (Verified Working)

Paperclip Issue (BHAA-1339)
  → Assigned to Sandbox Dev agent
    → Heartbeat/wakeup triggered
      → OpenCode runs in git repo workspace
        → Reads AGENTS.md
        → Writes code (src/hello.py, tests/test_hello.py)
        → Runs tests (pytest passes)
        → Commits to git (conventional commit)
      → OpenCode session completes
    → Paperclip posts agent comment
  → Issue marked done
