Astra full review

Read .claude/skills/codex-fullreview/SKILL.md and follow its complete execution contract: local preflight, the required .agents/skills/impartial-review/SKILL.md check (when it is absent, stop and point to astra-review, not codex-review), exact scope, unique run directory, source manifest, the author brief (written to $RUN/brief.md and named in the prompt unless the user asks for a fully blind review), plain codex exec launch that reads .agents/skills/impartial-review/SKILL.md by file and acts as its Manager, process completion, report identity, the sub-reviewer spawn count, finding verification, and honest attribution. This entrypoint changes only the defaults:

Skip the newest-Sol check in codex-fullreview Step 1; this entrypoint never swaps Astra for Sol. Honor an explicit user model/effort choice. Confirm supported local options before inference; a model identifier in this file is not proof of availability. $ARGUMENTS carries scope as in codex-fullreview.

Example for a branch diff after creating a fresh $RUN directory (POSIX shell):

mkdir -p .tmp
RUN=$(mktemp -d .tmp/astra-fullreview-XXXXXXXX)
git fetch origin main
BASE=$(git merge-base origin/main HEAD); HEAD_SHA=$(git rev-parse HEAD)
codex exec -s read-only -m gpt-6-astra -c model_reasoning_effort=medium -o "$RUN/report.md" "Read .agents/skills/impartial-review/SKILL.md completely and act as its Manager on the branch diff: base $BASE, head $HEAD_SHA. Read the diff with git diff $BASE $HEAD_SHA. Spawn fresh-context sub-reviewers with spawn_agent, fork_turns \"none\", model gpt-6-astra, reasoning_effort medium, as the skill directs; each is a leaf reviewer. Start no codex exec or other reviewer CLI process; if agent tools are missing, say so in the report. Author brief: $RUN/brief.md; give it only to the intent reviewer, as the skill directs; every other sub-reviewer gets the diff without it. No file edits, no Git writes, no publication. Verify the sub-reviewers' findings and write the final verified report. First line: Scope: base $BASE, head $HEAD_SHA. Second line: Sub-reviewers: <number spawned>." < /dev/null > "$RUN/run.log" 2>&1

Commit and uncommitted prompts (with the Astra model and effort in place of Sol and high), the root-commit base, the file-named skill invocation and prompt escaping, the session-file checks for skill load and spawned children, the scope-line check, and attribution follow codex-fullreview. Zero spawned children is reported as "no sub-reviewers ran", never hidden.

On PowerShell use a GUID-named directory and supported stdin/output redirection as described in codex-fullreview. Distinct prefixes do not prevent collisions between two Astra invocations; every run must still be unique.

If Astra is unavailable, report that outcome. Do not silently inherit another model or attribute a fallback to Astra. A rejected Astra id is reported, never retried on another model; any other failure gets the one automatic retry from codex-fullreview. A retry uses a new directory and reports its observed model/effort, or explicitly marks model resolution unverified. Keep lifecycle fixes in codex-fullreview rather than forking them here.
