What it does
Model is an agent skill from serpro69/claude-toolbox. Produce or update a domain-reference kit — the durable glossary + divergences/traps pages for a bounded context. Use for domain modelling, information architecture, building a domain glossary or domain model, mapping domain concepts to code (bindings), or surfacing the decidable questions stakeholders must close before design. Runs upstream of feature $kk:design as the first producer of the architecture flow, and emits artifacts $kk:review-architecture verifies. Triggers: "model the domain", "build a glossary"…
Its SKILL.md is about 1.4k tokens, which your agent loads only when the skill is triggered. The skill folder holds 68 other files (for example `archaeology.md`, `evals/brownfield-update/eval.json` and `evals/brownfield-update/oracle/gold-deltas.json`).
It sits in Development, covering Domain-driven design, UX design and Architecture decision records. The repository describes itself as: Minimal by design, explicitly multi-lang, production-ready and battle-tested collection of configs and plugins for your Claude Code agentic development workflows: mcp, configs…
When your agent uses it
- Domain modelling
- Information architecture
- Building a domain glossary
- Mapping domain concepts to code (bindings)
Example prompts
- “model the domain”
- “build a glossary”
- “domain reference”
- “/model”
Workflow steps
2 steps, taken from the first numbered list in SKILL.md.
- Load instructions. Read model-process.md (the detailed seven-phase workflow), archaeology.md, kit-contract.md, all four shared guards…
- Execute the seven phases per model-process.md
What it can do on your machine
Read from SKILL.md and the folder at commit c2d28c9. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships script files (Go, from the files we listed), which the agent can run.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Model loads about 1.4k tokens when it runs. Until then it costs about 164 tokens; SKILL.md has 554 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 554 words (~1,445 tokens).
“Goal: produce a provenance-clean domain-reference kit and, above all, a decision queue of precise, role-tagged questions a human can close. The queue is the primary output — artifact count and model sophistication are explicitly not the metric.”

When should I use Model?
Model fits situations like: domain modelling; information architecture; building a domain glossary; mapping domain concepts to code (bindings).
How do I install Model in Claude Code?
Run `npx skills add serpro69/claude-toolbox --skill model -a claude-code`. Or copy the skill folder (kodex-plugin/skills/model in serpro69/claude-toolbox) into .claude/skills/model in your project. Claude Code loads it when a task matches its description.
How do I install Model in Codex?
Run `npx skills add serpro69/claude-toolbox --skill model -a codex`. Or copy the skill folder (kodex-plugin/skills/model in serpro69/claude-toolbox) into .agents/skills/model in your project. Codex loads it when a task matches its description.
Can I use Model in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add serpro69/claude-toolbox --skill model -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/model, .gemini/skills/model, .github/skills/model and .opencode/skills/model in your project.
What does Model need to run?
Going by SKILL.md and its folder, Model needs Go for the scripts in its folder.
Does Model access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is Model safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
What licence does Model use?
Model has a licence file (the repository's licence) that doesn't match a standard licence. Read it on GitHub before reusing the skill.
How many tokens does Model use?
About 1.4k tokens (SKILL.md is roughly 5.8k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
What are the alternatives to Model?
