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

cyberarian 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 11d ago.

The scan reads SKILL.md. This mod also ships 4 executable files (scripts/archive_docs.py, scripts/index_docs.py, scripts/init_docs_structure.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Cyberarian - Document Lifecycle Management

This skill enforces a structured approach to documentation in Claude Code projects, ensuring consistency, discoverability, and automatic maintenance.

Core Principles

  1. Structured Organization: All persistent documentation goes in docs/ with semantic categorization
  2. No Temporary Docs in docs/: Ephemeral/scratch documents belong in /tmp or system temp, never in docs/
  3. Metadata-Driven: YAML frontmatter enables automation and lifecycle management
  4. Automatic Maintenance: Indexing and archiving happen automatically, not manually
  5. Context Efficiency: Bulk operations delegate to subagents to preserve main context

Context-Efficient Operations

The Problem

Document management operations can produce verbose output that pollutes the main agent's context:

  • Validation scripts listing many errors across files
  • Index generation scanning dozens of documents
  • Archive operations listing all files being moved
  • Search results returning many matches

The Solution: Subagent Delegation

Delegate to Task subagent for operations that return verbose output. The subagent absorbs the verbose output in its isolated context and returns a concise summary (<50 tokens).

Delegation Rules

Execute directly (simple, low-output):

  • Creating a single document from template
  • Reading a specific document's metadata
  • Checking if docs/ directory exists

Delegate to Task subagent (complex, verbose):

  • Running validation across all documents
  • Regenerating the index
  • Archiving operations (especially dry-run)
  • Searching documents by tag/status/category
  • Summarizing INDEX.md contents
  • Any operation touching multiple files

Delegation Pattern

When verbose output is expected:

1. Recognize the operation will be verbose
2. Delegate to Task subagent with explicit instructions
3. Subagent executes scripts, absorbs output
4. Subagent parses and returns summary <50 tokens
5. Main agent receives only essential summary
