## What it does

The command walks `analysis/$system/` and `modernized/$system*/` and lays out a stage-by-stage table: intent, preflight, assess, map, extract-rules, review, brief, harden, uplift, transform, reimagine, equivalence, verify. Each artifact is listed with whether it exists and when it last changed. It also counts rules flagged in `RULE_REVIEWS.json` that a person has not ruled on yet, and modules whose `VERIFICATION.md` is missing or older than the code — those count as not proven.

Then it hunts for stale files. A brief older than `ASSESSMENT.md`, `topology.json` or `BUSINESS_RULES.md`. `TOPOLOGY.html` older than `topology.json`. `TRANSFORMATION_NOTES.md` older than `BUSINESS_RULES.md`. Every hit comes with the step to rerun. Secrets hygiene gets its own pass: does `analysis/.gitignore` cover `SECRETS.local.md` and `*.local.patch`, is `SECRETS.local.md` untracked, has it ever been committed. Fail either check and the command says so loudly, then recommends rotating the secrets and scrubbing history.

It closes with three lines: where you are, what is stale, and the next command to paste. Reading is all it does, with one exception — it rebuilds `analysis/$system/REPORT.html` via `python3 "${CLAUDE_PLUGIN_ROOT}/scripts/build_report.py" $system`. No `python3` on the machine, or the script errors out? You get a one-line note and the rest of the report still runs. The system name is required; without it there is nothing to inspect.

## Install

### Claude Code (native platform)

1. **Plugin marketplace**
In the agent chat (not a shell):
```text
/plugin install code-modernization@claude-plugins-official
```

2. **Manually: put the files in place**
- File: `.claude/commands/modernize-status.md` — Call it with /modernize-status. For all projects use ~/.claude/commands/

### Codex

**Manually: put the files in place**
- File: `~/.codex/prompts/modernize-status.md` — Call it with /prompts:modernize-status. Codex marks this format deprecated in favour of skills

### GitHub Copilot

**Manually: put the files in place**
- File: `.github/prompts/modernize-status.prompt.md`

### Gemini CLI

**Manually: put the files in place**
- File: `.gemini/commands/modernize-status.toml` — Gemini stores commands as TOML: the prompt text goes into the prompt field

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/anthropics/claude-plugins-official/tree/HEAD/plugins/code-modernization/commands/modernize-status.md

## When to use it
- find out which modernization stage you are stuck on
- spot artifacts that fell behind their source files
- see how many flagged rules still await a human decision
- check whether `SECRETS.local.md` leaked into git
- get the exact command for the next step

## Example prompts
- Show the modernization status for `billing`
- Where are we with the `legacy-crm` system?
- What is stale, and what should I run next?

Report where the modernization of `$system` stands, in one screen. This command inspects and never modifies,
except that it refreshes `analysis/$system/REPORT.html` (`python3
"${CLAUDE_PLUGIN_ROOT}/scripts/build_report.py" $system`, a convenience: if it fails or `python3` is missing, say so in one line and carry on). If nothing
exists yet, the answer is `/code-modernization:modernize $system --source <path to the code>`, which asks what the person wants and starts preflight.

## 1 — Inventory

Check `analysis/$system/` and `modernized/$system*/` and build a table, one row per stage, with each artifact's
presence and modification time:

| Stage | Artifacts |
|---|---|
| intent | `INTENT.md` (what the person wants; written by `/code-modernization:modernize`) |
| preflight | `PREFLIGHT.md` (are the Check 0 human answers and the Check 6 scope-boundary finding there?), where `legacy/$system` points (does that directory exist?) |
| assess | `ASSESSMENT.md`, `ARCHITECTURE.mmd` |
| map | `topology.json`, `TOPOLOGY.html`, `*.mmd`, `extract_topology.*` |
| extract-rules | `BUSINESS_RULES.md`, `DATA_OBJECTS.md` |
| review | `RULE_REVIEWS.json`: how many flagged rules a person has decided (confirmed, wrong, needs discussion), and how many are still open |
| brief | `MODERNIZATION_BRIEF.md` (is the approval block signed?) |
| harden | `SECURITY_FINDINGS.md`, `security_remediation.patch` |
| uplift | `DELTA_CATALOG.md`, `BASELINE.md`, `PLAYBOOK.md` (no playbook means the pilot has not happened, so the fan-out must not), `modernized/$system-uplifted/UPLIFT_NOTES.md` (per unit: builds on target? baseline reproduced?) |
| transform | each `modernized/$system/<module>/`: tests present? `TRANSFORMATION_NOTES.md` present (its completion marker)? |
| reimagine | `modernized/$system-reimagined/`: per-service acceptance tests, and the `CLAUDE.md` handoff (its completion marker; it does not write `TRANSFORMATION_NOTES.md`) |
| equivalence | `EQUIVALENCE.json`: cases executed, same, differs (any differing or missing case, or zero executed, is a failure) |
| verify | `VERIFICATION.md` (written by `/code-modernization:modernize-verify`): the verdict per built module (PROVEN, PARTLY PROVEN or NOT PROVEN) and whether a person has signed it. A built module with no `VERIFICATION.md`, or one older than the module's code or tests, is **not proven yet** |

## 2 — Stale

Flag any artifact older than one it derives from: the brief older than `ASSESSMENT.md`, `topology.json` or
`BUSINESS_RULES.md` (no longer reflects discovery: rerun `brief`); an uplift's brief older than
`DELTA_CATALOG.md`, or with no catalog (phase order was decided without the version deltas: rerun `brief`);
`TOPOLOGY.html` older than `topology.json` (rerun the render step of `map`); a `TRANSFORMATION_NOTES.md` older
than `BUSINESS_RULES.md` (the module may not implement the latest rules: list which).

## 3 — Secrets hygiene

Does `analysis/.gitignore` exist and cover `SECRETS.local.md` and `*.local.patch` (`git check-ignore` in a git
```
