dx-domain

dx-domain is a skill for Claude Code, Codex from dikamilo/dx-workflow. It costs 74 tokens per session (674 once invoked), scanned A, original, MIT.

A workflow for keeping a project's glossary precise and up to date. A glossary is a shared list of what important domain terms mean in that project.

In plain words
What is it for?
Use it when a term is unclear, overloaded, conflicts with an existing definition, or becomes precisely defined during project work.
Why use it?
It prevents vague or conflicting words from causing misunderstandings in requirements, design, and code.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

dx-domain scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

The opening of the file, as written. The whole thing — 38 lines — stays where its author put it; the contents beside it link to each section on GitHub.

dx-domain

The active glossary discipline: challenge a term, sharpen it, and write it to foundation/glossary.md the moment it resolves. Merely reading the glossary for naming is a one-line habit any skill does — this skill is for changing the model, not consuming it. It fires on three triggers during any work:

  • Clash — a term contradicts an existing glossary definition. Call it out at once: "The glossary defines 'cancellation' as X, but you seem to mean Y — which is it?"
  • Fuzzy — a vague or overloaded term is in play. Propose one precise canonical term: "You said 'account' — is that the Customer or the User? Those are different things."
  • Resolved — a term gets nailed down during framing/design/implementation. Capture it immediately, before the moment passes.

Guard. Write only foundation/glossary.md. If context/foundation/ doesn't exist, the project isn't scaffolded — say so and suggest /dx-init. Create glossary.md lazily on the first resolved term.

Sharpen before you write (invoke dx-references with knowledge-layer)

Load knowledge-layer for the glossary entry shape and the standards/lessons/glossary distinctions. Then force precision:

  • Invent a concrete edge-case scenario that probes the boundary between two concepts and makes the user commit. Vague terms survive in the abstract and break on specifics.
  • Cross-check the code. If what the user says contradicts what the code does, surface it: "Your code cancels whole Orders, but you just said partial cancellation exists — which is right?"
  • Be opinionated. When several words mean one thing, pick the best and list the rest under _Avoid_.

Write inline, glossary-only

The moment a term resolves, add or edit its entry in foundation/glossary.md using the knowledge-layer entry shape — definitional, domain-only, one or two sentences (what it IS, not what it does). Don't batch. Skip general programming concepts (timeouts, retries, error types) — only terms unique to this project's domain belong.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
