  Govern stable domain context with a narrowly scoped CONTEXT.md when needed, and route hard-to-reverse decisions to ECC's existing architecture-decision-records skill. Use when domain terms require repeated explanation, one term has multiple meanings, unclear language causes module-boundary mistakes, or domain semantics must remain separate from architecture decisions.

Domain Context and Decision Handoff

Govern “what these business terms mean” separately from “why this option was chosen.” Do not create an empty shell when no stable content exists.

Domain Context Artifact: Domain Language Only

When terms require repeated explanation, one term has multiple meanings, or unclear language causes module-boundary errors, first reuse the repository's existing glossary/domain-model document or the context role in .governance/docs-map.json. Only when no equivalent exists should you lazily create the default CONTEXT.md from templates/context.example.md.

Record only:

  • domain terms and precise definitions;
  • relationships among core concepts;
  • confirmed ambiguities and the chosen interpretation;
  • ambiguities still awaiting confirmation from a domain owner.

Do not include implementation details, current state, task schedules, full requirements, decision rationale, or history. Keep those in code/MAP, STATUS/Issue Tracker, Spec, ADR, and LOG respectively. Terms must be traceable to code, contracts, or business evidence. Mark unconfirmed items as needs confirmation; do not guess.

ADR Handoff: Reuse the Existing Capability

This skill does not define a second ADR directory, numbering scheme, lifecycle, or template. When a decision is hard to reverse, would confuse a future reader without context, and involves a real tradeoff:

  1. Read and execute architecture-decision-records, preserving the repository's existing ADR location and format.
  2. If no convention exists, let that skill choose the minimum viable location; do not create a separate system here.
  3. Link to the ADR from CONTEXT.md, the project map, or the relevant Spec/Issue instead of copying the decision body.
  4. When a decision is accepted, superseded, or deprecated, append an event to project history according to the living-document rules.

Routine implementation details, easily reversible changes, and short-lived experiments do not need ADRs.

When to Activate

  • Domain terms are repeatedly re-explained or ambiguous language causes implementation drift.
  • The project needs a stable domain-language entry point but has no equivalent document.
  • Context work uncovers a durable decision that should be handed to architecture-decision-records.

When to Use

Use this skill when stable domain language needs one evidence-backed home, or when context work reveals a hard-to-reverse decision that belongs in the repository's existing ADR system.

How It Works

  1. Reuse the mapped context or glossary artifact when one exists; create CONTEXT.md only when no equivalent source of truth is available.
  2. Record precise domain definitions, relationships, confirmed interpretations, and explicitly unconfirmed ambiguities without mixing in implementation or task state.
  3. Route durable tradeoffs to architecture-decision-records and link the resulting ADR instead of copying its rationale into context documents.
  4. Keep schedules, blockers, and execution status in the existing issue tracker.

Examples

  • Define an overloaded business term once and link it to the code or contract that proves its meaning.
  • Mark a domain interpretation as needs confirmation until a domain owner resolves it.
  • Hand off a durable storage or boundary decision to the existing ADR workflow and link it from the context artifact.

Anti-Patterns

  • Copying current tasks, schedules, full requirements, or implementation details into CONTEXT.md.
  • Creating empty context files or a second ADR system for completeness.
  • Treating unconfirmed domain interpretations as facts, or copying ADR bodies into maps and logs.

Scheduling and Task Boundary

Keep tasks, status, blockers, and schedules in the project's existing tracker, such as GitHub Issues or Linear, as the single source of truth. Use local .scratch/ only when no external tracker exists and the project explicitly adopts it. Do not put schedules in CONTEXT.md, ADRs, PROJECT_STATUS, or the history index database.
