# /flow-next:audit — agent-native memory staleness review

Memory entries decay. A `.flow/memory/bug/runtime-errors/` entry logged six months ago might reference a renamed file, a deleted function, or a codepath that no longer exists. Without periodic review, the store accumulates zombie entries and `memory-scout` surfaces outdated advice.

This skill IS the audit. The host agent (Claude Code / Codex / Droid) walks `.flow/memory/`, reads each entry, uses Read/Grep/Glob/git to verify references against the current codebase, applies engineering judgment, and decides per entry whether to **Keep / Update / Consolidate / Replace / Delete**. Optional autofix mode applies unambiguous actions and marks ambiguous as stale.

Decision entries (`.flow/memory/knowledge/decisions/`) and glossary terms (`GLOSSARY.md` files at the repo root and on the ancestor chain) are walked alongside the rest of memory. Decisions get a calibrated judging question — "does the constraint that motivated this choice still hold?" — and Replace becomes a two-step supersession (write successor, mark old `decision_status: superseded`, never `git rm`). Glossary terms are scanned for code usage; zero-hit terms get a `<!-- stale: ... -->` HTML comment via Edit tool (no `flowctl glossary mark-stale` exists), `_Avoid_` aliases appearing in code surface as alias-creep findings.

There is no Python audit-engine, no codex/copilot subprocess dispatch, no deterministic scorer. The host agent is already an LLM and does the work directly. flowctl provides only thin persistence plumbing (`memory mark-stale`, `memory mark-fresh`, `memory search --status`) — landed by Task 2 of this spec.

**Read [workflow.md](workflow.md) for the full phase-by-phase execution. Read [phases.md](phases.md) for the 5-outcomes lookup with memory-schema-specific calibration.**

## Preamble

**CRITICAL: flowctl is BUNDLED — NOT installed globally.** `which flowctl` will fail (expected). Define once; subsequent blocks (here and in `workflow.md`) use `$FLOWCTL`:

```bash
FLOWCTL="$HOME/.codex/scripts/flowctl"
[ -x "$FLOWCTL" ] || FLOWCTL=".flow/bin/flowctl"
```

**Inline skill (no `context: fork`)** — `plain-text numbered prompt` must stay reachable across phases. Subagents can't call plain-text numbered prompts (Claude Code issues #12890, #34592). Phase 3 (Ask) and Phase 6 (Discoverability check) both require user choice in interactive mode.

## Mode Detection

Parse `$ARGUMENTS` for the literal token `mode:autofix`. If present, strip it from the arguments — the remainder is the scope hint.

```bash
RAW_ARGS="$ARGUMENTS"
MODE="interactive"
if [[ "$RAW_ARGS" == *"mode:autofix"* ]]; then
 MODE="autofix"
 # Strip token, collapse whitespace, trim.
 SCOPE_HINT=$(printf "%s" "$RAW_ARGS" | sed 's/mode:autofix//' | tr -s ' ' | sed 's/^ //;s/ $//')
else
 SCOPE_HINT="$RAW_ARGS"
fi
```

| Mode | When | Behavior |
|------|------|----------|
| **Interactive** (default) | User is at the terminal | Ask decisions on ambiguous cases via plain-text numbered prompt; confirm batched actions; run discoverability check with consent |
| **Autofix** (`mode:autofix` in arguments) | Ralph or batch usage | No user questions. Apply Keep/Update/Consolidate/auto-Delete/Replace-with-sufficient-evidence directly. Mark ambiguous as stale. Print the full report. Discoverability surfaces as a recommendation, not an edit |

### Autofix mode rules

- **No user questions.** Never call the plain-text numbered prompt.
- **Process all entries in scope.** No scope-narrowing question. If no scope hint was provided, process every categorized entry.
- **Attempt all safe actions.** Keep (no-op), Update (write tool), Consolidate (merge + `git rm` subsumed), auto-Delete (only when code AND problem domain both gone), Replace (only with sufficient evidence to write a trustworthy successor).
- **Mark ambiguous as stale.** When classification is genuinely ambiguous (Update vs Replace vs Consolidate vs Delete) or Replace evidence is insufficient, run `flowctl memory mark-stale <id> --reason "..."` instead of guessing. Stale-marking writes are atomic and round-trip safe.
- **Conservative confidence.** Borderline cases get marked stale; never deleted on autofix.
- **Always print the full report.** The report is the sole deliverable — there is no user to ask follow-ups.

## Interaction Principles (interactive mode only)

In autofix mode, skip user questions entirely and apply the rules above.

In interactive mode, follow these principles:

**Ask the user via plain text.** Render the options below as a numbered list `1.` … `N.`, followed by a final option `N+1. Other — type your own answer`. Print the question, then the numbered list, then **stop and wait for the user's next message before continuing**. Parse the reply as: a bare number `1`–`N+1` → that option; the literal text of an option label → that option; free text after `Other` → custom answer.

- Ask **one question at a time** via `plain-text numbered prompt`. Never silently skip the question.
- Prefer **multiple choice** when natural options exist.
- Lead with the **recommended option** and a one-sentence rationale.
- Do **not** ask the user to make decisions before evidence is gathered — Phase 1 investigates first, Phase 3 asks.
- Group obvious Keeps and obvious Updates together for batched confirmation. Present Consolidate / Replace / Delete one at a time.

The goal is automated maintenance with human oversight on judgment calls — not a question for every finding.

## Forbidden

- **Auditing legacy flat files** (`.flow/memory/pitfalls.md`, `conventions.md`, `decisions.md` at the memory root). Skip with a warning that recommends `/flow-next:memory-migrate` first. Report includes the skipped count.
- **Auditing under `_audit/`, `_review/`, or any other `_*` directory** under `.flow/memory/`.
- **Deleting silently.** Delete is reserved for unambiguous cases (code gone AND problem domain gone). Default to Replace or Consolidate when there's still value to preserve.
- **`git rm` on superseded decision entries.** Decision history stays on disk. Replace for `knowledge/decisions/` entries means write a new entry and mark the old `decision_status: superseded` with `superseded_by: <new-id>` — never delete the old file.
- **Deleting glossary terms.** When a term has zero code hits, mark stale via Edit-tool HTML comment. Removing the term entry is the operator's call, surfaced in the report.
- **Inventing flowctl subcommands** beyond what fn-34 task 2 ships (`memory mark-stale`, `memory mark-fresh`, `memory search --status`). fn-38 task 2 ships only `glossary {add,list,read,remove}` — there is no `flowctl glossary mark-stale`; use Edit tool. Use Write tool + git for moves and deletes.
- **Mass-renaming code from a glossary alias-creep finding.** The audit reports file:line locations and stops there; code rename is the operator's call.
- **Auto-committing without user awareness in interactive mode.** Phase 5 detects git context and asks. Autofix uses sensible defaults.
- **Setting `context: fork`** — plain-text numbered prompt must stay reachable.
- **Running parallel replacement subagents.** Investigation subagents can run in parallel for 3+ independent entries; replacement subagents run sequentially to protect orchestrator context.

## Pre-check: local setup version

Same pattern as `/flow-next:plan` and `/flow-next:prospect` — non-blocking notice when `.flow/meta.json` `setup_version` lags the plugin version:

```bash
if [[ -f .flow/meta.json ]]; then
 SETUP_VER=$(jq -r '.setup_version // empty' .flow/meta.json 2>/dev/null)
 PLUGIN_JSON="${DROID_PLUGIN_ROOT:-${CLAUDE_PLUGIN_ROOT:-$HOME/.codex}}/.codex-plugin/plugin.json"
 PLUGIN_VER=$(jq -r '.version' "$PLUGIN_JSON" 2>/dev/null || echo "unknown")
 if [[ -n "$SETUP_VER" && "$PLUGIN_VER" != "unknown" && "$SETUP_VER" != "$PLUGIN_VER" ]]; then
 echo "Plugin updated to v${PLUGIN_VER}. Run /flow-next:setup to refresh local scripts (current: v${SETUP_VER})." >&2
 fi
fi
```
