description: >-
  Compacts the current conversation into one self-contained, tool-agnostic handoff document at
  docs/handoffs/<slug>.md so any fresh agent or teammate can resume the work from that file
  alone. References pushed artifacts by path or URL, inlines anything not on the remote, and
  redacts secrets and PII. Re-running on an existing handoff offers enhance or overwrite.
  Writes one project artifact and, when needed, a private scratchpad backup; never commits.

Handoff

Step 1: Slug and focus

Derive a kebab-case `<slug>` from the user's arguments if given (e.g., "finish the migration tests" → `migration-tests`), otherwise from the conversation's most recent active thread; with no arguments, state the inferred topic and slug in one line before continuing. Record a **Focus for next session** only on a clear signal — verbatim user arguments or an explicitly stated next objective. Never manufacture one: with no signal, omit it and leave direction to the resumer.

Step 2: Locate the doc; create, enhance, or overwrite

Resolve the root: when `git rev-parse --is-inside-work-tree` returns `true`, use `git rev-parse --show-toplevel`, including in a linked worktree or subdirectory. Otherwise read `$CLAUDE_PLUGIN_ROOT/skills/init/references/multi-repo-detection.md` and apply it, then cover both of its non-workspace answers: when it finds **exactly one child repo**, treat that child repo as the root — writing above it would put the handoff outside version control, where the Step 5 `/optimus:commit` recommendation cannot reach it; when it finds **no recognized structure**, use the current directory. A multi-repo workspace uses its workspace root. The handoff folder is `docs/handoffs/` under that root. Then branch:

• **`<slug>.md` exists** → read it, then `AskUserQuestion`: **Enhance** (merge new context; keep still-valid content and append a History line) or **Overwrite** (fresh rewrite). Follow an already explicit choice without asking again. Before replacing existing content, confirm its exact current bytes are recoverable in Git; otherwise copy them to the session scratchpad and report the backup path. If no private scratchpad is available, preserve the file and write a new slug instead. Never claim uncommitted content is in Git history.
• **No slug match but other handoffs exist** → list them (filename · title · Last updated), then `AskUserQuestion`: **Continue one** (pick via a follow-up question, adopt that file's slug as `<slug>`, treat as Enhance) or **Create new**.
• **Folder empty or absent** → create new.

Step 3: Classify artifacts against version control

Per repo (per child repo in a multi-repo workspace, where paths and SHAs are also repo-qualified): find the branch and short HEAD SHA for **Origin**, each path's tracked / modified / staged / untracked status, and unpushed commits via `git log --oneline @{upstream}..HEAD` (fallback `origin/HEAD..HEAD`; no upstream or detached HEAD → treat local commits as unpushed). Not a git repo → note "not a git repo" in **Origin** and inline everything. Sort every artifact into three buckets:

1. **Tracked and pushed** → reference by repo-relative path / SHA / URL, never inline. 2. **Tracked-but-modified, staged-not-committed, or committed-not-pushed** → inline the relevant content (diff, file body, or commit message) — another clone will not have it. 3. **Untracked** → inline.

Step 4: Draft or reconcile

If the conversation has not already established the codebase's current state, briefly verify it in the repo before asserting it. Fill the **Handoff document template**. **New or overwrite** → write fresh. **Enhance** → keep still-valid content; update **Current state** (and **Goal**/**Next steps** if present) to current reality, dropping completed steps; preserve and extend decisions and open questions, promoting any the new work resolved; add new artifacts; refresh **Last updated**; append one **History** line.

• Prioritize knowledge a fresh agent could not re-derive from code or git history — decisions and why, rejected alternatives, constraints, gotchas, open questions.
• Never duplicate tracked-artifact content — reference by path plus a one-line summary. Inline only bucket-2 and bucket-3 content.
• Trust git state over chat memory when they conflict; if the current state is ambiguous, say so in one line rather than guessing.
• Keep the document tool-agnostic: "a fresh agent" / "a new session" — never a named AI product.

Step 5: Redact, write, verify, report

Redact as you write: every line of the document — references, authored prose, and inlined content — must be checked against the **Redaction patterns** table before it goes to disk, with matches replaced by the exact marker `[REDACTED: <kind>]` and the structure preserved (e.g. `DATABASE_URL=postgres://app:[REDACTED: password]@db:5432/app`). Inspect URL userinfo, query parameters, and fragments for credentials or signed-access tokens; retain the public resource location after removing sensitive access data, or use a non-clickable redacted reference when no public URL is usable. Ordinary paths and SHAs need no prose rewrite, but are not exempt from secret scanning. A file whose name looks like a secret is never inlined with its values, regardless of tracked state — see the table's last two rows. This file is destined for `/optimus:commit`, and removing a leaked credential from Git does not revoke it.

Write the document to `docs/handoffs/<slug>.md`, creating the folder if missing.

Then verify: read the file back from disk and re-scan the full document, including every reference and URL, against the **Redaction patterns** table, fixing any hit before you report. This pass checks what actually landed; it reduces exposure risk but is not a guarantee that every secret has been detected.

Report the written path and any scratchpad backup. If the resolved root is not itself a git repo — a multi-repo
