Setup Toolbox Context

Purpose

Scaffolds the domain-documentation convention that grill-with-docs and improve-codebase-architecture rely on: a CONTEXT.md glossary at the repo root (or per bounded context) and a docs/adr/ directory for architecture decision records. Detects existing state, asks only when the layout is genuinely ambiguous, and creates stubs lazily so the repo never carries empty placeholder files.

Workflow

1. Explore Current State

   • Check the repo for existing context and ADR scaffolding before writing anything
   • Files to detect: CONTEXT.md, CONTEXT-MAP.md, docs/adr/, and any src/*/CONTEXT.md (signals a multi-context repo)
   • Example: ls CONTEXT*.md docs/adr/ 2>/dev/null; find src -maxdepth 3 -name "CONTEXT.md" 2>/dev/null
   • Report findings concisely to the user before touching anything

2. Determine Layout

   • IF: CONTEXT-MAP.md exists OR multiple src/*/CONTEXT.md files exist → multi-context layout, skip to step 4
   • IF: CONTEXT.md exists at root → single-context layout, skip to step 4
   • IF: neither exists AND user passed --single or --multi → use that
   • IF: neither exists AND no flag → ask user once: "Single context (one CONTEXT.md at root) or multi-context (CONTEXT-MAP.md + per-module CONTEXT.md, typically a monorepo)?" Default to single-context — most repos are.
   • Example: monorepo with src/ordering/, src/billing/, src/fulfillment/ directories → recommend multi-context

3. Create Stubs Lazily

   • Do NOT create empty files. Only create scaffolding when there is real content to put in it.
   • IF: single-context AND no CONTEXT.md exists → ask user for the first 1-3 domain terms they want to define, then create CONTEXT.md with those terms following the format in ../grill-with-docs/references/CONTEXT-FORMAT.md
   • IF: multi-context AND no CONTEXT-MAP.md exists → ask user for the names and one-line descriptions of their bounded contexts, then create CONTEXT-MAP.md pointing at where each lives
   • IF: docs/adr/ does not exist → create the directory with a single docs/adr/README.md stub that explains the convention and links to ../grill-with-docs/references/ADR-FORMAT.md. Do NOT create 0000-template.md or empty placeholder ADRs.
   • Example: user gives "Order, Invoice, Customer" → write CONTEXT.md with those three terms, each with a one-line description and _Avoid_: aliases the user provides

4. Update CLAUDE.md or AGENTS.md (Optional)

   • IF: a CLAUDE.md or AGENTS.md exists at the repo root AND does not already mention CONTEXT.md
   • THEN: ask user whether to add a short "Domain Documentation" section pointing at CONTEXT.md and docs/adr/. Default: yes.
   • Example: append a section like "## Domain Documentation\n- CONTEXT.md is the project glossary; reach for it before introducing new terms.\n- docs/adr/ records architectural decisions. See setup-toolbox-context and grill-with-docs for the conventions."
   • Skip silently if no agent-instructions file exists — don't create one just for this.

5. Report and Hand Off

   • List the files created or modified, with absolute paths
   • Suggest the next move: invoke /grill-with-docs to start populating the glossary and recording ADRs from real conversations
   • Example: "Created /path/to/CONTEXT.md with 3 seed terms. Created /path/to/docs/adr/ with README stub. Next: run /grill-with-docs on your current design conversation to grow the glossary and capture ADRs inline."

References

CONTEXT.md format and rules

• IF: writing the initial CONTEXT.md or CONTEXT-MAP.md, or deciding what belongs in the glossary
• THEN: Read ../grill-with-docs/references/CONTEXT-FORMAT.md
• EXAMPLES:
  • "what does a CONTEXT.md entry look like?"
  • "how do I structure a multi-context repo?"
  • "should this go in CONTEXT.md or an ADR?"

ADR format and when to record

• IF: writing the docs/adr/README.md stub or explaining the ADR convention
• THEN: Read ../grill-with-docs/references/ADR-FORMAT.md
• EXAMPLES:
  • "what does an ADR look like?"
  • "when is something ADR-worthy?"
  • "how should ADRs be numbered?"

Works well with

This skill is the substrate the methodology family reads. Run it once; the rest degrade gracefully without it (falling back to plain language).

• grill-with-docs — reads and writes the CONTEXT.md and docs/adr/ this scaffolds.
• living-plan, tdd, improve-codebase-architecture, zoom-out — all consume the CONTEXT.md glossary and/or docs/adr/ decisions it creates.
