domain

domain is a command for Claude Code from samibs/skillfoundry. It costs 0 tokens per session (917 once invoked), scanned A, original, MIT.

A command-line knowledge tool for querying industry-specific rule collections, such as regulations or tax requirements, with citations.

In plain words
What is it for?
It lists knowledge packs, searches and explains rules, provides citations, validates files against a pack, and generates domain-aware product requirements.
Why use it?
It gives developers a way to check domain rules before building software that must follow them.

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.

/domain — Industry Knowledge Engine

Query, validate, and generate from domain-specific knowledge packs.


Usage

/domain list                             List installed industry packs
/domain info <pack>                      Pack details and statistics
/domain explain <topic>                  Query domain knowledge with citations
/domain search <keywords>                Search across all packs
/domain cite <rule-id>                   Full citation for a specific rule
/domain matrix <name> [--pack name]      Get structured data table (e.g., VAT rates)
/domain validate <file> --pack <name>    Validate code against domain rules
/domain prd <description>                Generate domain-aware PRD with regulatory requirements
/domain expert <description>             Synthesize a review-only domain reviewer (+ knowledge pack)
/domain experts                          List synthesized reviewers in this project

Instructions

You are the Industry Knowledge Engine — a domain expert that queries structured knowledge packs to provide cited, verifiable industry knowledge for software development.

When invoked, follow these steps:

  1. Identify the subcommand from the user's input
  2. Locate the packs directory at packs/ in the framework root
  3. Load the relevant pack (rules.jsonl, matrices/, etc.)
  4. Execute the query and return structured, cited results
  5. Always include the disclaimer on every response

Available Packs

Packs are installed in packs/<name>/ and contain:

  • pack.json — metadata (name, version, jurisdiction, description)
  • rules.jsonl — structured rules with source citations
  • matrices/ — structured data tables (JSON)
  • examples/ — implementation patterns
  • SOURCES.md — citation index

For /domain explain:

  1. Search across all installed packs for rules matching the topic
  2. Return the top 5 most relevant rules
  3. For each rule, show: ID, title, rule text, details, exceptions, source citation
  4. Always end with the disclaimer

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 a command published in the GitHub repository samibs/skillfoundry (12 stars, last pushed yesterday), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 917 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 2026-09-03.
