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

leankg-rule 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 8d 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.

Origin

This is a copy

What it actually says

LeanKG Mandatory Rule

MANDATORY 4-Tier Search Fallback Chain

Tier 1: LeanKG MCP (mcp_status → search_code / find_function / query_file)
Tier 2: leankg CLI (leankg query "X" --kind name)
Tier 3: rtk (rtk grep "X" --path .)
Tier 4: grep/rg (LAST RESORT)

LeanKG MCP Tools

  1. mcp_status - Check readiness first
  2. search_code("X") - Find by name/type
  3. find_function("X") - Function definitions
  4. query_file("*X*") - Files by name
  5. get_impact_radius(file) - Change impact
  6. get_context(file) - Read content
  7. get_dependencies(file) - Imports
  8. get_dependents(file) - Reverse deps
  9. get_callers("func") - Who calls
  10. get_call_graph("func") - Full graph

ABSOLUTE BANS

  • NEVER skip to grep when LeanKG available
  • NEVER use Glob before LeanKG for code
  • ONLY exception: non-code files (config, docs)

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.
