# SE Orchestrator: routes questions to the right knowledge packs

**This is an orchestrator, not a knowledge pack.** It carries **no source content**.
On explicit `/se <question>` it matches your question to installed catalogue packs,
reads them, and answers with pack and chapter citations.

## When to use
**Prerequisites:** none: plain Markdown; works on any host that loads Agent Skills. Pair it with the packs it routes to.

`/se` answers systems-engineering questions by consulting installed packs. It is an
entry point, not a knowledge base. Use it when you do not already know which `/<slug>`
to open.

## How /se answers

### Modes

| Mode | When | Gate |
|---|---|---|
| Narrow consult | One Topics row matches, at most one agency named, no compare/contrast/survey verb | None. Best single pack. End with "Also relevant" runners-up. |
| Broad consult | Two or more Topics rows, two or more agencies, or a compare/contrast/survey verb | One plan approval naming packs and why, then run to done. Disagreements under "Where the sources differ"; never average or blend. |
| Deliverable | An artifact verb (draft, write, produce, prepare, build, review, verify) plus a Deliverables row name or keyword | Plan approval, then stage pauses after Draft and after Review (Verify is last). |

### Routing

1. Match Topics keywords case-insensitively, with synonym judgement (e.g. "V&V" hits verification and validation rows).
2. When the question names an agency that survives the filter, keep only packs that also appear on that Agency contexts row.
3. No match: name the three closest Topics rows, suggest a rephrase or a direct `/<slug>`, and make **no SE claims**.

### Reading

A pack lives at `../<slug>/` from this folder. For each selected pack: read its
`SKILL.md` index; open at most two chapters from its Topic Index / Chapter Index;
open one support file (`glossary.md`, `patterns.md`, or `cheatsheet.md`) only for
term, technique, or decision-rule questions. At most four packs total.

### Citations and Sources

Cite only files read this session, in these forms: `[slug chNN]`, `[slug index]`,
`[slug glossary|patterns|cheatsheet]`. Every answer ends with a **Sources** block
listing each pack's slug, its `**Source**` line, and its licence.

## Host modes

Pick the highest mode the host can run:

| Mode | When | Behaviour |
|---|---|---|
| Fan-out | Sub-agents available | One brief per pack in parallel; main thread composes the answer. |
| Sequential | No sub-agents, member files readable | Same briefs one at a time; write each pack's notes before opening the next. |
| Index-only | Transform installs (Codex, Gemini, Cursor rules) | Read sibling index files when readable: `~/.codex/prompts/<slug>.md`, `~/.gemini/commands/jgs-se-knowledge-packs/<slug>.toml`, `./.cursor/rules/<slug>.mdc`. Cite `[slug index]` only and label the answer `index-level: chapter bodies not installed`. |
| Route-only | No member file readable | Report the routing decision and the `/slug` commands only. Make **no SE claims**. |

Narrow consults read in the main thread on every host. A missing routed pack is
noted and skipped; if none remain, fall back to route-only.

## Scope & Limits

- No SE claim without a citation from a pack file read this session.
- The map is curated, not exhaustive. Agency rows are a filter, not an endorsement.
- At most six packs per Topics row. At most four packs read per answer.
- Deliverable stage chains come only from Deliverables rows; empty cells skip that stage.
- `/se` never overwrites an existing file without a yes at a gate.
