domain

A guide for using a repository's domain documentation, meaning project-specific terms, background, and architecture decisions, while exploring its code.

In plain words
What is it for?
Use it when inspecting code, naming issues or tests, checking architectural decision records, and recording new domain terms or decisions.
Why use it?
It keeps reviews and proposed changes aligned with the project's established vocabulary and past architectural decisions. It also makes missing documentation visible instead of silently inventing terminology.

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.

Per session 0 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 251 The whole file, excluding the scripts and references it only reads on demand.

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

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 yesterday.

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 it actually says

Domain Docs

How the engineering skills should consume this repo's domain documentation when exploring the codebase.

Layout

This repo uses a single-context domain documentation layout.

Expected files, when they exist:

  • CONTEXT.md at the repo root
  • docs/adr/ for architectural decision records

These files do not need to exist before a skill can run. If they are absent, proceed silently. Producer skills such as /grill-with-docs can create them later when real terminology or decisions need to be recorded.

Before exploring, read these

  • CONTEXT.md at the repo root, if it exists.
  • ADRs under docs/adr/ that touch the area about to be changed, if any exist.

Use the glossary's vocabulary

When output names a domain concept in an issue title, refactor proposal, hypothesis, or test name, use the term as defined in CONTEXT.md.

If the concept is missing from the glossary, either reconsider whether that term belongs in the project language, or note it as a gap for /grill-with-docs.

Flag ADR conflicts

If output contradicts an existing ADR, surface it explicitly instead of silently overriding the decision.

Changes

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.

domain is an agent published in the GitHub repository yuqie6/ProductFlow (301 stars, last pushed 6d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 251 tokens. 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 2026-08-30.
