🔍 Cross-Code Review — OpenCode Adapter Implementation, Fix Round 4 (Job b3aa4b6f)

• Reviewer: planner-reviewer-claude-01
• Target diff: cumulative working-tree diff, confirmed via git status --short/git diff --stat to match the brief exactly. This round is a near-byte-identical superset of the already-approved 3473d7e3 round.
• Method: rather than re-reading the entire diff line-by-line (already thoroughly verified across three prior rounds — a65aaf9f NOT PASS, b6fd3987 PASS, 3473d7e3 PASS), I isolated the actual delta first: .agents/skills/lib_py/agents/adapters/opencode.py's diff header shows blob hash 9e5d01b — identical to the hash I already verified in 3473d7e3 — confirming the adapter itself is byte-for-byte unchanged. git diff --stat line counts match the prior round exactly file-for-file except tests/test_tier1_unit.py (+18 lines). I focused verification on that one real delta.

---

1. The Actual Delta — OPENCODE_PERMISSION Export Syntax Change (Positive)

create_session.sh/resume_session.sh changed from the parameter-expansion form I validated last round:

export OPENCODE_PERMISSION="${OPENCODE_PERMISSION:-{\"*\":\"allow\"}}"

to an explicit conditional with a plain single-quoted literal:

if [ -z "${OPENCODE_PERMISSION:-}" ]; then
  export OPENCODE_PERMISSION='{"*":"allow"}'
fi

I did not assume equivalence — reproduced this directly:

$ bash -c 'unset OPENCODE_PERMISSION; if [ -z "${OPENCODE_PERMISSION:-}" ]; then export OPENCODE_PERMISSION='"'"'{"*":"allow"}'"'"'; fi; printf "VALUE=[%s]\n" "$OPENCODE_PERMISSION"'
VALUE=[{"*":"allow"}]
$ python3 -c 'import json,os; print(json.loads(os.environ["OPENCODE_PERMISSION"]))'
{'*': 'allow'}

Clean, valid JSON — no regression from the fix already validated in 3473d7e3. This new form is arguably more robust than the previous one: it sidesteps nested-quote-escaping entirely (the exact class of bug that slipped through the b6fd3987 round) by using a plain single-quoted literal in a context where single quotes are actually meaningful shell quoting, rather than embedding an escaped JSON literal inside a ${VAR:-word} expansion already nested in an outer double-quoted context.

2. Expanded Test Coverage — Previously-Untested "Preset" Path Now Covered

The new test additions in tests/test_tier1_unit.py::test_opencode_shell_and_scripts_integration add a scenario I hadn't seen tested before: verifying that if a caller has already set OPENCODE_PERMISSION (e.g., to {"*":"deny"}), the script's if [ -z ... ] guard correctly leaves it untouched rather than clobbering it with the default:

res_c_preset = subprocess.run([...], env={**os.environ, "OPENCODE_PERMISSION": '{"*":"deny"}'}, ...)
assert json.loads(res_c_preset.stdout.strip()) == {"*": "deny"}

Both create_session.sh and resume_session.sh get this preset-path assertion alongside the unset-path assertion. This closes a real test-coverage gap (not a bug — bash's :- semantics already respected a preset value correctly in the prior syntax too — but it was never explicitly asserted before now).

3. Everything Else — Confirmed Unchanged From the Already-Verified 3473d7e3 Round

• opencode.py adapter: byte-identical (blob hash match) — the real-schema (directory/time_created ms) fix, _resolve_db()'s live opencode db path invocation, and all other adapter behavior already independently verified (including against a scratch copy of the real production database schema in b6fd3987) carry forward unchanged.
• reconcile.sh's drift-C block, including its DRY reuse of the adapter's _resolve_db() via get_adapter('opencode'), is unchanged.
• All 29 lockstep wiring points (run_loop.sh, status.sh, lib.sh, registry.py, atomic_yaml.py, verify_session.py, workspace_uuid.py, 6 skill scripts, update_yaml_resumed.sh, orc_onboard.sh) are unchanged and were already verified across the prior two rounds.
• Diff-stat line counts confirm this: every file matches the prior round's insertion/deletion counts exactly except test_tier1_unit.py.

4. Test Suite

Independently ran the full suite myself:

.venv/bin/python -m pytest tests/ -q
→ 447 passed in 761.60s (0:12:41), exit code 0

Same count as the prior round (the new preset-path checks are additional assertions inside an existing test function, not new test functions, so the total count is unchanged as expected). Zero failures, zero regressions.

---

5. Verdict

This round's only real change is a stylistic-but-meaningfully-more-robust rewrite of the OPENCODE_PERMISSION default-export logic (avoiding nested-quote fragility entirely) plus genuinely useful new test coverage for the preset/override-respecting path. Independently verified both are correct via direct bash reproduction. Everything else in the diff is confirmed byte-identical to the 3473d7e3 round I already thoroughly reviewed and passed (including the schema-correctness fix validated against a real production database in b6fd3987). Full suite green, 447/447, zero regressions.

[VERDICT: PASS]
