effect-qa-mcp: Skill for Claude Code

.agents/skills/ubiquitous-language/SKILL.md

ubiquitous-language is a skill for Claude Code from forthy/effect-qa-mcp. It costs 70 tokens per session (1,050 once invoked), scanned A, original, no licence file.

A glossary-building skill for Domain-Driven Design (DDD), a way to model software around the words and concepts used by a business. It finds important terms in the conversation, points out unclear meanings, and saves the proposed glossary in UBIQUITOUSLANGUAGE.md.

In plain words
What is it for?
Defining business terms, resolving terminology disagreements, and creating a shared glossary for a domain model.
Why use it?
It helps teams avoid using different words for the same idea or the same word for different ideas. This makes discussions and domain models easier to keep consistent.

Skill for Claude Code

Written for Claude Code: disable-model-invocation in frontmatter. Also seen: installed under .agents/ (shared by several agents).

This is forthy/effect-qa-mcp's own configuration. It tells Claude Code how to work on effect-qa-mcp itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything effect-qa-mcp configures →

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

ubiquitous-language 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.

What this file has done since we first saw it

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.
