dx-domain-discover

dx-domain-discover is a skill for Claude Code from dikamilo/dx-workflow. It costs 21 tokens per session (627 once invoked), scanned A, original, MIT.

A workflow that reads an existing codebase and records its domain vocabulary in a project glossary. Domain vocabulary means the names and terms the software already uses for its concepts.

In plain words
What is it for?
Use it to create or extend a glossary for a whole repository or a selected module, provided the project has already been initialized with a glossary file.
Why use it?
It gives later development work a shared set of names, reducing inconsistent terminology across code and documentation.

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-discover 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 10d 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.

How it starts

The opening of the file, as written. The whole thing — 42 lines — stays where its author put it; the contents beside it link to each section on GitHub.

dx-domain-discover

Bootstrap foundation/glossary.md from an existing codebase. Mine the code for the ubiquitous language already living in it — the terms the domain uses — and write them down so every later skill names things consistently. This is the one-time (per-module) extraction pass; /dx-domain keeps the glossary sharp during ongoing work. Re-runnable: pass [module or path] to scope the sweep to one area and grow the glossary incrementally.

Guard. foundation/glossary.md must exist (seeded by /dx-init) — if it is missing, tell the user to run /dx-init first, then stop. Read the current glossary before mining so you extend it, never clobber it.

Invoke dx-references with knowledge-layer for the glossary entry shape and the standards/lessons/glossary distinction — this skill writes the glossary and nothing else.

1 — Mine the vocabulary

Spawn built-in Explore subagents (fan-out, read-only), scoped to [module or path] when given, else the whole repo. Harvest candidate domain terms from:

  • Identifiers — type/class/entity names, enums, key function and method names.
  • Module and package names — the boundaries the code already draws.
  • Comments and existing docs — READMEs, ADRs, doc-comments where terms get defined in prose.

Keep only terms specific to this domain. Drop general programming concepts (cache, retry, handler, DTO) — they are not ubiquitous language.

2 — Resolve and write

For each surviving term, write a glossary entry in the shape from knowledge-layer (**Term**: definition — domain-only, no implementation. _Avoid_: confusable term). Be opinionated: when several names map to one concept, pick one and list the rest under _Avoid_.

Surface, don't average. When you find a term clash (two definitions for one word) or a fuzzy/overloaded term, do not guess — list it and ask the user to resolve it, then record their decision. Keep the file glossary-ONLY: no implementation detail, no rationale, no decisions (those are lessons).

dx-domain-discover is a skill published in the GitHub repository dikamilo/dx-workflow (5 stars, last pushed yesterday), licensed MIT. It adds 21 tokens to every session and 627 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
