004-write-article

name	004-write-article
description	Creates a new article document following XDR article standards: selects scope, type, subject, and number; then writes a focused synthetic text that combines and links multiple XDRs, Research documents, and Skills around a topic. Activate this skill when the user asks to create, add, or write a new article, guide, or overview document within an XDR project.

Overview

Guides the creation of a well-structured article by following _core-adr-004, consulting xdr-standards for every core element definition, researching the XDRs, Research documents, and Skills to synthesize, and producing a concise document that serves as a navigable view without duplicating decision content.

Instructions

Phase 0: Clarify Intent

Before reading any standards, ask the user clarifying questions to gather the information needed to proceed. Use the vscode_askQuestions tool with all questions in a single call.

Mandatory questions (ask only if not already provided by the user):

• Topic: What is the article about? (skip if the user already stated it)
• Audience: Who is the intended reader? (e.g., new developers, product managers, external contributors) MUST always be asked explicitly; never infer from context.
• Scope: Which XDR scope should contain the article? (default is _local; confirm or ask only if context is ambiguous)

Optional questions (ask only when genuinely unclear):

• Type: Should the article primarily synthesize ADRs, BDRs, or EDRs? Ask only when the topic spans multiple types.
• Existing XDRs: Are there specific Decision Records or Skills you want the article to reference or synthesize?

Do NOT proceed to Phase 1 until you have at minimum a clear topic and audience.

Phase 1: Understand the Article Goal

1. Read .xdrs/_core/adrs/principles/004-article-standards.md in full to internalize the template, placement rules, numbering rules, and the constraint that articles are views, not decisions.
2. Read .xdrs/_core/adrs/principles/001-xdrs-core.md in full before defining the article's core elements. Treat it as the canonical source for how to choose and write type, scope, subject, numbering, naming, and folder placement.
3. Confirm the topic and intended audience gathered in Phase 0. Do NOT proceed without a clear topic.

Phase 2: Select Scope, Type, and Subject

Consult 001-xdrs-core while making each choice in this phase. The summaries below are orientation only; when any detail is unclear, the standard decides.

Scope — use _local unless the user explicitly names another scope.

Type — match the type of the XDRs the article primarily synthesizes (adrs, bdrs, or edrs). If the topic spans multiple types, use adrs. Use the same rules as 002-write-xdr Phase 2:

• BDR: business process, product policy, strategic rule, operational procedure
• ADR: system context, integration pattern, overarching architectural choice
• EDR: specific tool/library, coding practice, testing strategy, project structure, pipelines

Subject — pick the subject that best matches the article's topic (required list per type is in _core-adr-001). If the article spans more than one subject, place it in principles.

Phase 3: Assign a Number and Name

1. List .xdrs/[scope]/[type]/[subject]/articles/ (create the folder if it does not exist).
2. Find the highest existing article number in that namespace and increment by 1. Never reuse numbers.
3. Choose a short lowercase kebab-case title that describes the topic clearly.
   • Good: onboarding-guide, checkout-flow-overview, api-design-principles
   • Avoid: summary, notes, misc

Phase 4: Research XDRs and Skills to Synthesize

1. Read all XDRs, Research documents, and Skills relevant to the article topic across all scopes listed in .xdrs/index.md.
2. Evaluate XDR metadata before synthesizing guidance. All documents present in the collection are considered active. Use Valid: to determine the convergence date for adoption, Applied to: to determine whether the decision fits the audience or context being discussed, and the decision text itself for any remaining applicability boundaries.
3. Identify the key points a reader needs to understand the topic end-to-end.
4. Collect XDR IDs and file paths for cross-references. Never copy decision text verbatim; link to it.

Phase 5: Write the Article

Use the mandatory template from 004-article-standards:

# [scope]-article-[number]: [Short Title]

## Overview

[Brief description of what this article covers and its intended audience. Under 40 words.]

## Content

[Synthetic text combining and explaining the topic. Use links to Decision Records, Research documents, and Skills
when referencing information from those documents. Keep under 1950 words total.]

## References

- [XDR id or Skill name](relative/path/to/file.md) - Brief description of relevance

Rules to apply while drafting:

• Write for the stated audience; avoid jargon unexplained elsewhere.
• Every factual claim must link back to the authoritative XDR or Skill.
• If the article advises readers what to do, clearly separate active/applicable XDRs from background, historical, or out-of-scope ones.
• Never reproduce decision text verbatim; summarize and link.
• Prefer plain Markdown, tables, or ASCII art for simple structure, flow, layout, or relationship indications.
• If the article genuinely needs local images or supporting files, store them in .xdrs/[scope]/[type]/[subject]/articles/assets/ and link with a relative path.
• Keep the article under 1950 words; move detailed content to XDRs or Skills.
• Use lowercase file names. Never use emojis.
• If a conflict exists between the article and a Decision Record, note it and defer to the XDR.

Phase 6: Place and Register

1. Save the file at .xdrs/[scope]/[type]/[subject]/articles/[number]-[short-title].md.
2. Add a link to the article in the canonical index for that scope+type (.xdrs/[scope]/[type]/index.md).
3. Add back-references in the XDRs, Research documents, and Skills that the article synthesizes, under their ## References section.

Examples

Input: "Write an article about how skills work in this project."

Expected actions:

1. Read 004-article-standards.md.
2. Topic: how skills work. Audience: developers new to the project.
3. Scope: _local, type: adrs, subject: principles.
4. Scan .xdrs/_local/adrs/principles/articles/ — no articles exist → number is 001.
5. Research _core-adr-003, _core-adr-006, and the existing skill SKILL.md files.
6. Write .xdrs/_local/adrs/principles/articles/001-skills-overview.md following the template, linking to _core-adr-003 and the individual skill files.
7. Update .xdrs/_local/adrs/index.md with a link to the new article.
8. Add a reference to the article in _core-adr-003 under ## References.

Edge Cases

• Article vs. XDR confusion — if the user asks for a document that makes a decision, write an XDR (use the 002-write-xdr skill), not an article.
• Cross-subject topic — place the article in principles, not in any single subject folder.
• No existing articles folder — create it; it is optional in the folder layout.
• Conflicting information found — note the conflict in the article and always defer to the XDR.
• Article would exceed 1950 words — move detailed content to a new Research, Skill, or XDR and link back.

Constraints

• MUST consult 001-xdrs-core as the canonical source for every core element definition, especially type, scope, subject, numbering, naming, and placement.
• MUST follow the article template and placement rules from 004-article-standards.
• MUST keep scope _local unless the user explicitly states otherwise.
• MUST defer to active and applicable XDRs when article synthesis conflicts with them.
