rules

rules is a command for coding agents from AcKeskin/contexture. It costs 26 tokens per session (240 once invoked), scanned A, original, MIT.

A command for managing architectural rules: written guidelines about how a codebase should be structured and designed across company, user, and project levels.

In plain words
What is it for?
Use it to list, inspect, enable, disable, edit, or synchronise architectural rules.
Why use it?
It makes the active rules visible and explains which rule takes priority when settings overlap. Changes are previewed and confirmed before they are written.

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

rules 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

Run the rules skill for the architectural-rule overlay system.

Text after /rules is the subcommand. Examples:

  • /rules list — show the effective corpus, grouped by tier, non-default rules annotated.
  • /rules where csharp/naming — explain how one rule resolves (which tier wins, why).
  • /rules edit csharp/naming — create/open a user override (whole-file or field patch).
  • /rules disable web/state [--project | --session] — turn a rule off at the chosen scope.
  • /rules enable web/state — undo a disable.
  • /rules sync — clone/pull the company rules repo per the manifest.

Every mutating subcommand previews the before→after effect on the effective corpus and confirms before writing. Mode A only — never auto-fires.

See ~/.claude/skills/rules/SKILL.md for the full procedure and ~/.claude/docs/architectural-rules-overlay.md for the model.

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.
