Skills listed in `codex/excluded-skills.txt` also carry `compatibility: Designed for Claude Code (or similar products)` so spec-aware clients know they are Claude-only.

 - Judge whether that implementation is finished. The original ask is usually in the session conversation — compare it against what the diff delivers — and the diff itself signals incompleteness: TODO/FIXME markers it introduces, stubbed or never-wired functions, failures mentioned in the session but never fixed. If work remains, write a brief (goal from the original ask, what's already in place, what remains, definition of done), record `plan: brief` and put the brief's text under a `## Brief` section at the end of the state file (a later resume in a fresh session has no other copy), and leave `implement` unrecorded so the resume point lands on Step 4 to finish the job — and skip the test-gap dispatch below, since Step 4 dispatches its own tester with that brief. If the work looks complete, or there's no evidence either way, record `implement: done` — simplify and the review loops take it from there.
 - If `implement` was recorded done and the tree is clean with branch commits → also `simplify-commit: <HEAD sha>`.
 - Open PR on the branch → `pr: <number>`.
-- Review steps are never inferred — leave them pending. Re-reviewing already-reviewed work is cheap; skipping an un-run review isn't.
+- Review steps are inferred only from the `ran-report.sh --json` output, and only when that step's row reads `fresh`: those two rows count only the record a review skill writes when it finishes, not the one the hook writes when the command is submitted, and `fresh` means no commit since it belongs to an earlier step. A review abandoned at the prompt leaves only the hook's record, so its row does not read `fresh` and the step runs again. Seed `review-code` from a fresh `review-code` row and `reviews-addressed` from a fresh `address-pr-reviews` row, recording the current HEAD sha. Trust the row's own `status`; do not re-derive staleness by comparing its `sha` to HEAD, because a step that commits always leaves its attributed sha behind HEAD and the seed would never survive. A `stale`, `missing`, or `pending` row seeds nothing and the step runs again. Never infer a review step from the working tree or the PR alone — re-reviewing already-reviewed work is cheap; skipping an un-run review isn't. When the log is empty (a branch that predates the hooks), every row reads `pending` and nothing is seeded, which is the old behavior.
 - If the adopted diff (dirty files plus commits since the merge-base with the default branch) touches testable code but no test files, dispatch `unit-test-writer` in the background now, prompted with the diff: write tests for the changed behavior, match existing test conventions, report which fail. Note the gap in the position report. Fold the results in at the next commit — resuming at Step 5, collect after the `simplify` skill so the tests ride the same commit; resuming later, collect before Step 7 starts, reconcile guessed names against the real code, run the suite, and commit via `Skill("commit", args: "--force Add tests for $SLUG")`. Skip the dispatch for diffs with no testable behavior (docs, config).
 - Nothing to resume (clean tree, no branch commits, no PR, no `TASK`) → stop and ask the user what to build.

+# /ran
+
+Answers one question: which steps of the workflow have already run against this branch?
+
+The log behind it is written by hooks, not by this skill, so it survives a `/clear`, a compaction, and a new session. Both invocation paths are recorded: commands you type (`UserPromptSubmit`) and ones the model invokes through the Skill tool (`PostToolUse`).
+
+## Steps
+
+1. Run the report:
+
+   ```bash
+   scripts/ran-report.sh
+   ```
+
+   Add `--json` only when another skill is consuming the output. The report always covers the current branch: its commits come from the checkout, so there is no flag to point it elsewhere.
+
+2. Print the checklist verbatim. It is already formatted; do not restyle it, re-sort it, or convert it to a table.
+
+3. If anything is outstanding, offer to run those steps in pipeline order. Do not run them without being asked.
+
+## Reading the markers
+
+| Marker | Meaning |
+| --- | --- |
+| `✓` | Ran, and no commit since it belongs to an earlier step |
+| `⚠` | Ran, but the branch has moved underneath it in a way that step should see again |
+| `✗` | Never ran, and the last required step before it has |
+| `·` | Never ran, and it is not yet its turn |
+
+Staleness is decided by attributing each commit to the most recent command logged before it, not by comparing shas to HEAD. A step commits *after* it runs, so its own work always lands at a later sha than the one it logged; only a commit belonging to an earlier step, or to no command at all, means the step needs another pass.
+
+A command only claims a commit made within an hour of it, since a step commits within minutes of being invoked. A commit that lands long after the last command is one you made by hand, and hand-written work is exactly what the steps before it need to see again. Override the hour with `RAN_ATTRIBUTION_WINDOW` (seconds).
+
+## What the log does and does not prove
+
+- For most steps an entry means the command was **invoked**, not that it succeeded or that it changed anything. `✓ simplify` means you ran it.
+- `review-code` and `address-pr-reviews` are the exception: their rows count only the record a review skill writes as its last action, so `✓` there means the pass finished. A review abandoned at the prompt reads `✗`.
+- That exception is only as wide as the callers that write it. `/go`, `/review-fix-cycle`, and `/address-pr-reviews` record completion. A bare `/review-code` does not, because that skill lives outside this repo, and neither does `/code-review`, which is built into Claude Code. A review run either of those ways reads as never run and the step gets offered again.
+- History starts when the hooks were installed. A branch older than that reads empty until it sees new activity, and its pre-existing entries never satisfy the two review steps.
+- Hooks are what record an invocation, so only Claude Code sessions on this machine write those. A step run from Codex, from a cloud `/code-review ultra`, or on another machine leaves no invocation entry. A skill that records its own completion is the exception again: it writes wherever it runs, Codex included.
+
+Say so plainly when it matters. Outside the two review steps, never present a `✓` as proof the step succeeded.
