 A successful structured review run produces one GitHub review summary (with its inline comments), which `/review-pr` updates in place with the run link. `/review-pr` never calls `gh pr comment` or the issue comment API itself. It may still return a short final assistant message after submitting the review; `opencode github run` posts that as a separate top-level completion comment, so a run can produce the review plus at most one additional completion comment — not necessarily exactly one top-level artifact.
 
-The bundled toolkit ships an `external_directory` permission in `.opencode/opencode.jsonc` (copied into `~/.config/opencode/` with the rest of the toolkit) that denies by default, so a stray attempt to read outside the checked-out repository, such as inspecting `/opt/pipx/logs/*` after a failed tool install, is denied immediately instead of blocking on the default "ask" prompt, which nothing can answer in a non-interactive GitHub Actions run and would otherwise hang until `timeout-minutes` kills it. The narrow allow-list contains only the three trusted helpers (`resolve-app-token.sh`, `review-pr-gh.sh`, and `review-pr-submit.sh`) under `~/.config/opencode/scripts/` and the fixed `context.json`, `initial.json`, and `update.json` files under `~/.config/opencode/review-state/` that those helpers use.

OpenCode evaluates access to those state files through the directory wildcard, so the allow rule matches `~/.config/opencode/review-state/*` while the orchestrator's edit permission remains limited to the two payload files.
