Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00059 | $0.00750 |
| Opus 5 | $0.00030 | $0.00375 |
| Sonnet 5 | $0.00012 | $0.00150 |
| Haiku 4.5 | $0.00006 | $0.00075 |
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 6d 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.
This is a copy
95% identical to ubiquitous-language — 1 line differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
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.
Mine the live conversation for domain-relevant nouns, verbs, and concepts; resolve synonyms and overloaded terms into a canonical, opinionated glossary. Persist the result to UBIQUITOUS_LANGUAGE.md so subsequent sessions inherit the same vocabulary. Re-invocation refines the file in place rather than overwriting.
When a candidate term collides with usage already present in the codebase, dispatch an Explore agent (fd-first discovery, git grep/ast-grep content search) to confirm the dominant naming before recommending a winner. The user supplies domain intent; the codebase supplies factual usage.
Modality vs adjacent skills: This skill extracts glossary from raw conversation when no documented domain language exists yet. Domain-model grilling grills a plan against an already-documented CONTEXT.md/ADRs. Pick ubiquitous-language when you are creating the artifact; pick the grilling workflow when you are stress-testing one. The two compose: build the glossary here, then promote stable terms into CONTEXT.md and let the grilling workflow defend it thereafter.
Process
- Scan the dialogue for domain-relevant nouns, verbs, and concepts. Skip generic programming nouns (array, function, endpoint) unless they carry domain weight.
- Identify three failure modes: same word for different concepts (ambiguity), different words for the same concept (synonyms), vague or overloaded terms.
- Propose canonical terms with explicit aliases-to-avoid. Be opinionated — pick one winner per concept and justify briefly.
- Persist
UBIQUITOUS_LANGUAGE.mdto the working directory using the format inreferences/UBIQUITOUS-LANGUAGE-FORMAT.md. - Emit a short inline summary of additions, renames, and flagged ambiguities so the user can react in-thread.
Rules
- One sentence per definition. Define what the term is, not what it does.
- Group terms into multiple tables when natural clusters exist (subdomain, lifecycle, actor). Force no grouping when a single cohesive table reads cleanly.
- Express relationships with bold term names and explicit cardinality where obvious (
exactly one,one or more,optional). - Flagged ambiguities require a recommendation, not a question. The skill resolves; the user overrides.
- Treat module and class identifiers as glossary candidates only when they carry domain meaning. Prefer abstract domain terms over implementation aliases.
- Include an example dialogue (3–5 exchanges) demonstrating the terms used precisely. The dialogue clarifies boundaries between adjacent concepts.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

ubiquitous-language is a skill published in the GitHub repository OutlineDriven/odin-gemini-cli-extension (5 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 59 tokens to every session and 750 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. It is 95% identical to ubiquitous-language, differing in 1 line, and is treated as a copy.

design
Set visual and interaction direction for any UI surface (web, React, TUI, CLI, desktop, Qt, design-system tokens) before any UI code. Direction-first: generates 3-4 distinct directions via verbalized sampling, picks one via per-axis single-select, then derives palette, typography, spacing, motion budget. Loads when…
askme
Verbalized Sampling (VS) protocol for intent exploration before planning, mode-aware. Default exhaustive runs full VS; collaborative runs tip-sharing dialogue; adversarial walks the design tree one fork at a time. Auto-detects from phrasing ("help me refine" → collaborative, "poke holes" → adversarial); override via…
git-branchless
Enforce idiomatic git-branchless during planning and executing tasks — detached-HEAD-first work, in-memory rebase via git move, event-log recovery via git undo, deferred branch creation, speculative-merge git sync for base updates. Use when planning or executing multi-commit work, history rewrites, stack edits…
grill-ai-mastery
Hybrid interview that probes AI-engineering mastery by tip-vocabulary depth — entity referencing, loop closure, observability, harness improvement — not by token usage or LOC. Start collaborative (two-way tip exchange), escalate to adversarial probing when depth is lacking. Trigger when the user says "interview me on…
grill-me
Adversarial relentless interview against any plan or design until shared understanding is reached. Walk the decision tree, resolve dependencies one answer at a time, recommend a default per question. Trigger when the user says "grill me", "stress-test this", "interview me about this design", or otherwise asks for…

Proof-driven development. Use when implementing with formal verification using property-based testing, theorem proving, or proof tactics; zero unproven property policy enforced.
