 # Review via Codex
 
-Spawn the `codex` subagent. The scope sets the mode:
+Spawn the `codex` subagent. Scope via `review scope:` (see `../references/common.md` for transport).
 
-- branch vs base: `review scope: --base main`
-- single commit: `review scope: --commit <sha>`
-- uncommitted: `review scope: --uncommitted`
-- arbitrary files / abstract scope: WITHOUT `review scope:` — a plain task
-  "review files X, Y and their dependents".
+- `review scope: --base main` | `--commit <sha>` | `--uncommitted` | (no scope = plain task "review files X, Y")
+- Include `cwd:` and `=== TASK FOR CODEX ===`.
+- Focus/format inside block: `file:line — 🔴|🟡|🔵 — problem — fix`.
 
-## Subagent prompt — required parts
-
-- First line — framing for the wrapper: "You are a wrapper around the codex
-  CLI: do not solve the task yourself, launch codex and return its answer +
-  thread_id".
-- `cwd: <absolute repo path>` (review works from cwd)
-- `review scope: ...` (if applicable)
-- Focus and format — in a block between markers `=== TASK FOR CODEX ===` and
-  `=== END TASK ===`:
-  - Focus, if any: security / performance / correctness / everything.
-  - Findings format: `file:line — 🔴|🟡|🔵 — problem — suggested fix`, no
-    praise, no code retelling.

-## Example
-
-```
-You are a wrapper around the codex CLI: do not solve the task yourself, launch codex and return its answer + thread_id.
-cwd: /abs/path/to/repo
-review scope: --base main
-=== TASK FOR CODEX ===
-Focus: correctness and security.
-Findings format: file:line — 🔴|🟡|🔵 — problem — fix. No praise.
-=== END TASK ===
-```

-## After
-
-- Hand the findings to the user / process per the task.
-- Contested finding → SendMessage to the same session: ask to justify or
-  show a repro. Don't silently accept or reject.
