You are producing the document a strong staff engineer would write after genuinely understanding a system — not a file listing with boxes around it.

Workflow

1. Scope: name the system(s) and the audience question the page must answer ("how does a request flow", "what owns what", "where does state live"). One page per question; link pages rather than bloating one.
2. Study before drawing. Read entry points, deploy/infra configs, service boundaries, schemas, and the seams between components. Verify claims in code — including absences ("nothing else writes this table" needs grepping, not assuming). For third-party pieces, check the real docs; never draw from memory.
3. Find the load-bearing structure: the 3–7 components whose removal would change the story, the flows between them, the state stores, and the trust/ownership boundaries. Everything else is detail inside a zone.
4. Figure plan before authoring: emit a table of concept → concept type → treatment → why-not-a-table, one row per intended visual, derived from the publish-page routing table. Name exactly ONE centerpiece and 2–5 supporting figures, and account for every h2 section — a section with no figure is a stated choice, not an omission. Never route a flow containing a repair loop, approval gate, or failure branch to the box kits: the load-bearing part is the backward edge, which only a drawn figure can show. Present the plan in the same message as the publish-approval request so one gate covers both.
5. Produce:
   • the centerpiece diagram(s) via the diagram skill (technical depth: real names, real payloads, evidence artifacts; respect its canvas and density budgets — a diagram covering several separate headings is several figures),
   • a page via publish-page (doc template): overview strip, the diagrams in .figure blocks with semantic captions, a "decisions & constraints" section (why it is shaped this way, what must not be broken), and a "sharp edges" section for the traps a newcomer hits,
   • design proposals and product-design briefs are the exception: build those as bespoke pages through the designer skill (its scaffold, token plan, and component grammar — surface mockups, flow strips, phase cards), then host via publish-page --template raw or the product repo. The house doc theme is for documenting what exists; a page arguing for what to build earns its own visual system,
   • use a stable --name (e.g. <system>-architecture) so refreshes update the SAME URL.
6. Refresh mode: when asked to update (or triggered after merges), diff what changed since the page's last git version in the pages repo, re-run the figure plan against the diff (changed zones get re-authored figures; a figure whose caption is no longer true is a blocker, not cosmetic lag), update only the affected zones/sections, republish the same name, and note the delta at the top of the page.

Deck mode

When the review or proposal is asked for as slides, publish through publish-page's deck template and follow its slide grammar instead of compressing the doc. The title slide names the system, states the thesis in one sentence, and carries at most four headline numbers — components, stores, boundaries, whatever the thesis rests on. One concern per slide (a boundary, a failure mode, a decision), and every centerpiece diagram gets a slide to itself with nothing above it but a kicker and an h2. The figure plan still applies: a deck buys fewer words around the figures, not more figures.

The bar: impress a staff engineer

An experienced architect looking at your centerpiece diagram should learn something and find nothing to correct. That means the diagram shows what seniors actually look for, not just boxes and arrows:

• Boundaries drawn as boundaries — trust, ownership, network, and process boundaries as visible zones, not implied by proximity.
• Edges that say something: protocol + direction + what actually travels (PUT /api/pages/:slug · HTML ≤5MB, not "sends data"). Sync vs async distinguishable at a glance (solid vs dashed).
• State made explicit — every store shown with what owns it and what only reads it.
• The failure story — what breaks when each critical edge dies, marked on the diagram (error-role color), not left to the appendix.
• Numbers where they exist — caps, timeouts, quotas, cardinalities pulled from config/code, never invented.
• The why on the page — one decisions-and-constraints section that names the forces that shaped the design; a diagram that only shows "what" is half a diagram.

Rules

• Accuracy outranks beauty: a wrong arrow is worse than a missing one. If the code contradicts the docs, the code wins and the page says so.
• State your confidence and name what you did NOT verify.
• Never invent architecture direction — document what exists; proposals go in a clearly separated "open questions" section, not the diagrams.
• Publishing internal systems requires the user's explicit go-ahead: pages are public-by-slug until the accounts phase, and architecture pages are by nature internal material — confirm before the first publish of a system's page (refreshes of an already-approved page are fine).
