+name: codex-review-loop
+description: Review Toki uncommitted changes, branches, or commits with path- and semantic-routed specialist lanes, normalize P0-P3 findings, and optionally fix only findings the user explicitly approves. Use when the user asks for a local code review, review loop, review-and-fix pass, re-review, or approved finding remediation in the Toki repository. Keep GitHub review submission, PR comments, push, merge, and other remote writes outside this skill.
+---
+
+# Toki Codex Review Loop
+
+Run an rvw-compatible lane review, then apply the codex-lb-style approval,
+atomic-fix, verification, and bounded re-review loop.
+
+## Core Contract
+
+- Treat every review request as read-only until the user explicitly approves a
+  write mode.
+- Never infer permission to edit or commit from phrases such as "review this"
+  or from a GitHub `@codex review` request.
+- Never push, submit a GitHub review, comment, resolve threads, label, merge, or
+  otherwise mutate remote state from this skill.
+- Preserve unrelated staged, unstaged, and untracked changes. Never use
+  `git reset`, `git checkout`, or broad restoration to undo a finding fix.
+- Treat local usage logs, databases, audit findings, prompts, transcripts, and
+  credentials as sensitive. Do not print raw matched diff content.
+- Apply `project-conventions` and read its task-specific references before
+  fixing Toki source, tests, resources, or project configuration.
+- Apply `.agents/conventions/git-workflow.md` before any commit. A commit
+  requires explicit user authorization separate from review authorization.
+
+## Trust Boundary
+
+Scope resolution runs before any review and must survive a hostile repository.
+Treat this section as the contract a finding is measured against: report a
+finding when it breaks an invariant below, and classify it `wont_fix` with this
+section as the reason when it only restates a non-goal.
+
+### Untrusted Inputs
+
+- Repository file contents and tree layout, including untracked and ignored
+  paths.
+- Repository Git configuration: `.git/config`, `.gitattributes`, `.gitmodules`,
+  and any configured hook or helper program.
+- The inherited `PATH` and every `GIT_*` environment variable.
+- Lane result JSON, including every path and line number it reports.
+
+### Enforced Invariants
+
+1. Only trusted executables run. `git` and the review binary resolve from the
+   platform default path, never from an inherited `PATH`, and the runner narrows
+   `PATH` before invoking any external command.
+2. No repository-configured program executes. Content filters, `textconv`,
+   external diff, `core.fsmonitor`, `core.hooksPath`, and lazy fetch are
+   overridden to inert values or the scope is refused.
+3. Workspace confinement is derived from the filesystem, not from Git. The
+   inventory walks the real tree from the repository root and validates every
+   symbolic link target, so ignore rules and index modes cannot hide a path.
+4. Every scope fails closed. A submodule, embedded repository, escaping symlink,
+   non-UTF-8 path, or unbounded inventory marks the scope unsafe and stops before
+   Codex is invoked.
+5. Paths keep byte fidelity across process boundaries. Roots and path lists cross
+   as NUL-terminated data and are never trimmed.
+6. Reported findings are untrusted data. A finding path must be
+   repository-relative, free of NUL, and free of empty, current, or parent
+   segments before it is used.
+7. The baseline lane is always on. A registry that marks it otherwise is
+   rejected.
+
+Add a regression test with every change that touches an invariant, and name the
+invariant in the test.
+
+### Non-Goals
+
+- Sandboxing the host. This skill reduces what executes during review; it does
+  not isolate a repository the user already chose to open.
+- Restricting native review to the reviewed diff. `codex exec review` may read
+  other in-repository files by design, so confinement is to the repository root,
+  not to `changedPaths`.
+- Content-level secret detection inside reviewed changes. Exclusion is by path
+  pattern only.
+- Supporting attacker-chosen repository root paths, such as sibling names that
+  differ only by trailing whitespace. Exact roots are preserved, but the user is
+  assumed to name their own repository.
+- Byte-exact handling of non-UTF-8 paths. Such scopes are refused, not
+  supported.
+
+## Workflow
+
+### 1. Resolve One Review Scope
+
+Choose exactly one scope:
+
+- Use `--uncommitted` for staged, unstaged, and untracked changes.
+- Use `--base <branch>` for the current branch relative to a base branch.
+- Use `--commit <sha>` for one commit.
+
+Prefer an exact scope named by the user. Do not fetch or change branches merely
+to infer a scope.
+
+Run the resolver:
+
+~~~bash
+python3 .agents/skills/codex-review-loop/scripts/resolve_review_scope.py \
+  --repo . \
+  --uncommitted \
+  --pretty
+~~~
+
+Stop before invoking Codex when `safeToReview` is false or `hasChanges` is
+false. Excluded sensitive paths make the scope unsafe because
+`codex exec review --uncommitted` cannot exclude individual paths.
+
+### 2. Load Only Activated Review Rules
+
+Always read the common reviewer prompt and baseline lane. Read only the
+specialist lane files named by `activatedLanes`. Also read the finding schema
+and verification reference before reporting or fixing findings.
+
+Treat lane activation as additive. Never disable baseline correctness or
+security reasoning merely because a path pattern did not match.
+
+### 3. Run One Pass Per Activated Lane
+
+Run the baseline lane and every activated specialist lane:
+
+~~~bash
+.agents/skills/codex-review-loop/scripts/run_review_lane.sh \
+  --repo . \
+  --lane baseline \
+  --base main
+~~~
+
+The runner passes bounded lane instructions through Codex
+`developer_instructions`, uses the structured-output schema, requests an
+ephemeral Codex session, and refuses inactive or unsafe lanes. Run lanes
+sequentially by default. Do not add replicated reviewers or an adjudicator
+unless the user explicitly expands the workflow.
+
+### 4. Validate And Merge Findings
+
+Capture each lane's JSON result in a temporary directory, then merge:
+
+~~~bash
+python3 .agents/skills/codex-review-loop/scripts/merge_findings.py merge \
+  /tmp/toki-review/baseline.json \
+  /tmp/toki-review/remote-sync.json
+~~~
+
+Reject malformed results. Conservatively merge overlapping findings with a
+similar root cause, retain every contributing lane, use the highest priority,
+and surface materially conflicting priority opinions.
+
+### 5. Report Before Writing
+
+Present the normalized findings with ID, priority, confidence, location, impact,
+suggested fix, and verification plan. Then request one explicit mode:
+
+1. Report only.
+2. Fix selected findings without commits.
+3. Fix all actionable findings without commits.
+4. Fix selected findings and create one verified commit per finding.
+5. Fix all actionable findings and create one verified commit per finding.
+
+Treat "Fix P0/P1 only" as a valid selection. For a P0/P1 fix that changes
+existing product behavior rather than restoring clearly intended behavior,
+describe that behavior change and obtain a second confirmation.
+
+### 6. Fix One Finding At A Time
+
+Before each fix:
+
+1. Re-read the affected code and relevant `project-conventions` references.
+2. Inspect `git status` and the affected diff.
+3. Record the pre-fix state of only the files or hunks that will change.
+4. Use `apply_patch` for the narrow fix.
+5. Run the smallest verification profile that can prove the finding fixed.
+
+If verification fails, reverse only the patch introduced for that finding. If
+that boundary cannot be proven, stop and report the failure instead of risking
+the user's work.
+
+For `--uncommitted` reviews, default to no commits. Create atomic commits only
+when the user explicitly selects a commit mode and the new fix can be separated
+from pre-existing changes without staging unrelated hunks.
+
+### 7. Re-review With A Bound
+
+After approved fixes, rerun baseline plus only lanes affected by the fix. Stop
+after three total review rounds. If the same root cause returns in two
+consecutive rounds, mark it `wont_fix` with the reason instead of looping.
+
+Count externally triggered rounds against the same bound. A pushed branch can
+re-request review automatically, so a GitHub `@codex review` round is a round
+here too.
+
+Fix at the invariant, not at the reported case. When a finding names one variant
+of an invariant in the trust boundary, audit every other variant of that same
+invariant locally and fix them together in one change. Repairing only the
+reported case is what turns one finding into a new round, because the next round
+reports the next variant. Before pushing, state which invariant each fix
+restores and which adjacent variants were checked.
+
+### 8. Finish With A Local Report
+
+Report:
+
+- Review scope and activated lanes.
+- Findings fixed, skipped, `wont_fix`, or left for reporting only.
+- Verification commands and outcomes.
+- Commits created, if explicitly authorized.
+- Remaining risks or unverified checks.
+
+State explicitly that no push or GitHub write occurred.

+# Common Reviewer Contract
+
+Perform a read-only code review of only the native `codex exec review` scope.
+Use the `review-scope-json` payload to preserve the resolver's comparison mode.
+Do not edit files, create commits, or write remote state.
+Act as the leaf reviewer for the already-running loop. Do not invoke
+`codex-review-loop`, start another Codex process, or delegate another review.
+
+Inspect the changed code, the minimum surrounding implementation needed to
+understand it, and relevant tests. Report only actionable defects introduced or
+exposed by the reviewed change. Do not report optional refactors, naming
+preferences, general hardening ideas, or pre-existing issues that the change
+does not worsen.
+
+Use these priorities:
+
+- P0: Release-blocking widespread data loss, secret exposure, authentication
+  bypass, or a change that makes the primary product unusable.
+- P1: High-impact incorrect core behavior, security failure, crash, corruption,
+  or a likely production outage.
+- P2: Concrete functional, reliability, portability, or performance bug with
+  limited impact and a clear fix.
+- P3: Minor but real correctness or maintainability defect. Do not use P3 for
+  style nits or speculative improvements.
+
+For each finding:
+
+- Point to the smallest relevant line range in the reviewed diff whenever
+  possible.
+- Explain the failing scenario and observable impact.
+- State a root cause independently of the symptom.
+- Propose a narrow fix and a verification method.
+- Mask credentials, prompts, transcripts, database values, and other sensitive
+  content. Describe the data category instead of quoting it.
+- Use repository-relative paths. Never emit absolute paths or `..` segments.
+
+Return only JSON matching the supplied schema. Set `lane` to the selected lane
+ID. Use `verdict: "clean"` with an empty findings array when no actionable
+defects are found; otherwise use `verdict: "findings"`.

+# Verification Profiles
+
+Run verification only after the user authorizes fixes. During review-only mode,
+use read-only inspection commands and do not run `xcodegen generate` or other
+commands that rewrite files.
+
+## Profiles
+
+### common
+
+~~~bash
+git diff --check
+~~~
+
+### swift-package
+
+Use for root package, protocol, reader, durable-storage, and Agent changes:
+
+~~~bash
+swift test
+~~~
+
+For broad Agent changes, also build the release product:
+
+~~~bash
+swift build -c release --product toki-agent
+~~~
+
+### hub
+
+~~~bash
+swift test --package-path TokiHub
+swift build --package-path TokiHub -c release --product toki-hub
+~~~
+
+### app-format
+
+~~~bash
+swiftformat . --lint
+~~~
+
+### app-lint
+
+~~~bash
+swiftlint lint --strict --quiet
+~~~
+
+### app-tests
+
+~~~bash
+xcodebuild test \
+  -project Toki.xcodeproj \
+  -scheme Toki \
+  -destination "platform=macOS" \
+  CODE_SIGN_IDENTITY="" \
+  CODE_SIGNING_REQUIRED=NO \
+  CODE_SIGNING_ALLOWED=NO
+~~~
+
+### project
+
+After an explicitly approved `project.yml` or resource change:
+
+~~~bash
+xcodegen generate
+git diff -- Toki.xcodeproj
+~~~
+
+Include the generated project diff with the source configuration change.
+
+## Selection
+
+- Start with the narrowest profile named by the affected lane and path.
+- Run every affected package's tests for cross-package contract changes.
+- Run the full format, lint, package, Hub, and app test set before a PR or broad
+  source change.
+- Never print raw local logs, database rows, prompts, transcripts, audit
+  findings, or secret-bearing fixtures in test output.
+
+## Failed Verification
+
+1. Preserve the pre-fix user state.
+2. Identify the exact patch introduced for the current finding.
+3. Reverse only that patch with `apply_patch`.
+4. Mark the finding `skipped` with the failed command and concise reason.
+5. Stop instead of reverting when the fix boundary overlaps unrelated work.
