auk

auk is a skill for Claude Code, Codex from sandeepshekhar26/develop-anything. It costs 49 tokens per session (330 once invoked), scanned A, original, MIT.

A tool for analyzing a codebase and producing checked rules about its conventions, architecture, and dependencies. It can also generate context files that help AI assistants work within those rules.

In plain words
What is it for?
Use it to generate or verify AI context, review architectural changes, inspect dependency and call graphs, and manage project rules.
Why use it?
It replaces assumptions about how a project works with rules derived from the actual code, and can reveal when those rules no longer match the code.

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

auk 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 5d 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 it actually says

auk — AI context engineering

auk (npx -y auk-develop) generates, verifies, and compiles AI context from the actual codebase.

Commands

  • auk generate — analyze code → .auk/rules.yaml, graph.json, semantic.json, compiled context files
  • auk verify — re-check every rule against current code; reports context rot
  • auk review --diff <ref> — architectural diff review (layer violations, new cycles, god objects)
  • auk enhance --emit / --apply <json> — LLM enhancement loop (you write the JSON)
  • auk graph --open — interactive dependency/call-graph viewer
  • auk mcp — MCP server (tools: get_rules, get_architecture, get_call_graph, get_dependencies, get_enhancement_tasks, apply_enhancements, …)

Conventions

  • .auk/rules.yaml, graph.json, decisions.yaml, semantic.json should be committed; .auk/cache.json and .auk/prompts/ gitignored.
  • Never hand-edit compiled outputs (CLAUDE.md etc.); change rules and run auk compile.
  • When enhancing rules, never alter ids, severities, or verification blocks — only descriptions/rationales via the response schema.
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.
