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. Agency filter: when the question names agencies, keep candidates listed on those Agency contexts rows as long as one survives; otherwise keep all candidates and say no pack from that agency covers the topic.
3. Narrow pick: first-listed pack of the matched row after the filter; if that pack's Scope & Limits flags the question thin, take the next on the row. The consult stays narrow (no gate).
4. Broad pick: best-positioned candidate per named agency, then first-listed of each matched row, then second-listed, stopping at four, or earlier once every matched row and agency is represented and at least two packs are chosen.
5. 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 (native installs put members side by side). 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. If no chapter covers the question, record "no chapter in slug covers this" and use the index frameworks where they apply.

Each pack brief returns at most 10 claims of at most two sentences, each with a citation, plus a thin: line when Scope & Limits flags the question and a source: line copied from the pack's **Source** line. No claim from outside its pack.

Citations and Sources

Cite only files read this session, in these forms: [slug chNN], [slug index], [slug glossary|patterns|cheatsheet]. Drop uncited claims. Agreeing claims merge into one statement carrying every citation. Where the packs are silent, say so; no fallback to model memory. Every answer ends with a Sources block listing each pack's slug, its **Source** line, and its licence. Content-pack licences come from the Licences table, else the label Public Domain (US Government work). Signpost lines read MIT (signpost). Non-commercial and share-alike terms appear in full.

Deliverable stage chains

The matched Deliverables row is the chain. Draft / Review / Verify cells list the packs for each stage; an empty cell skips that stage (the plan says so). A review or verify request on a user-supplied artifact starts the chain at that stage.

• Draft builds the artifact from the Draft packs' guidance with inline citations, then pauses.
• Review lists cited findings against the Review packs' criteria and gives the revised artifact, then pauses.
• Verify reports a table of item, criterion, result, and citation, plus open items. It edits nothing and offers fixes as a follow-up.

Output goes in the reply unless the user names a file. A deliverable with no matching Deliverables row gets no improvised chain: name the closest Deliverables rows or offer a broad consult instead.

Edge cases

• Bare /se with no argument: print usage and three example questions (e.g. requirements quality, NASA risk process, hazard analysis draft).
• Sub-agent failure: rerun that brief in the main thread.
• Thin-pack step-down: if the selected pack's Scope & Limits flags the question thin, take the next pack on the row; the consult stays narrow.

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. On sub-agent failure, rerun that brief in the main thread.
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. Cite [slug index] only, name chapters as follow-ups, 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.

Native-root fallback. When the skill folder is not revealed, try ~/.claude/skills/, ~/.openclaw/skills/, ~/.copilot/skills/, each with and without the jgs-se-knowledge-packs/ namespace. Transform index files live at ~/.codex/prompts/<slug>.md, ~/.gemini/commands/jgs-se-knowledge-packs/<slug>.toml, and ./.cursor/rules/<slug>.mdc.

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.
