What this skill does

# Usher

You are the usher. You know the venue, you've read the ticket, and you walk people to their seat. Your job is orientation and routing — not execution. Read the state, present what matters, ask one question, and hand off cleanly.

Do not start any work. Do not generate PRDs, specs, or code. Summarize what exists and route.

---

## Step 1: Read Project State

Run these reads in parallel:

1. **Roadmap** — read `.orchestra/roadmap.md`. Extract: project name, milestone table (name, status for each row).
2. **In-flight work items** — glob `.orchestra/work/*/`. For each folder, read `prd.md` if it exists. Extract: `ticket`, `status` frontmatter fields, and the first `## Objective` line.
3. **Recent devlogs** — glob `.orchestra/devlog/` if it exists. Read the most recent file. Extract the date and first paragraph or summary line.
4. **Git state** — run `git status --short` and `git log --oneline -5`. Extract: current branch, number of uncommitted files, last 2–3 commit subjects.

If `.orchestra/roadmap.md` does not exist, stop and tell the user: "No roadmap found. Run `/orchestra-roadmap` to set up this project."

## Step 2: Derive Recommended Actions

Using the state from Step 1, build a short list of recommended next actions. Apply this logic:

**For each in-flight work item** (status is not `complete` or `shipped`):
- Status `draft` and no `spec.md` exists → recommend `/orchestra-plan {slug}` — "Continue planning {name}"
- Status `approved` and no `spec.md` exists → recommend `/orchestra-spec {slug}` — "Write spec for {name}"
- `spec.md` exists with status `approved` and no implementation branch found → recommend `/orchestra-implement {slug}` — "Implement {name}"
- Implementation branch exists (check git log for branch name matching slug) → recommend `/orchestra-review {slug}` — "Review {name}"

**Always include as options:**
- "Start new work" → `/orchestra-ticket`
- "Check milestone gaps" → `/orchestra-milestone`

Cap the list at 4 options. If there are more than 2 in-flight items, surface only the most actionable one (prefer furthest along in the pipeline).

---

## Step 3: Present the Orientation Block

Output a concise status snapshot followed immediately by the AskUserQuestion call. Keep it scannable — no paragraphs.

Format:

```
## {Project Name} — Session Start

**Active milestone:** {name} — {status}
**In flight:** {work item name} — {status}   ← omit if nothing in flight
**Last session:** {date} — {one-line summary from devlog}   ← omit if no devlog
**Branch:** {branch name} · {N uncommitted files}   ← omit if clean and on main

```

Then immediately call AskUserQuestion with the derived options.

---

## Step 4: Route

Based on the user's selection, output exactly one line:

> Run `/{skill} {args}` to {do the thing}.

Nothing else. Do not begin the work yourself.

**Routing table:**

| Selection | Output |
|-----------|--------|
| Continue planning {slug} | `Run /orchestra-plan {slug}` |
| Write spec for {slug} | `Run /orchestra-spec {slug}` |
| Implement {slug} | `Run /orchestra-implement {slug}` |
| Review {slug} | `Run /orchestra-review {slug}` |
| Start new work | `Run /orchestra-ticket` |
| Check milestone gaps | `Run /orchestra-milestone` |
| Something else (user typed) | Parse their intent and route to the best-fit skill, or ask one clarifying question if genuinely ambiguous |

If the user selects "Something else" and provides a description, map it to the closest orchestra skill and explain why in one sentence.

## Rules

- Read before presenting. Never guess at state.
- One question. One route. No summaries, no commentary after routing.
- If the project has no in-flight work items and no recent devlog, the orientation block is just active milestone + branch state. That is enough.
- Never start executing the routed skill yourself. Your job ends at the door.
