vilona

vilona is a skill for Claude Code from oyi77/1ai-skills. It costs 18 tokens per session (3,998 once invoked), scanned A, original, MIT.

A foundational infrastructure guide for an agent ecosystem, covering how requests are received, processed, stored, and returned. The description does not identify a specific developer-facing task beyond these general system functions.

In plain words
What is it for?
Use it for general input handling, state management, configuration, logging, and interfaces between agent skills.
Why use it?
It may help organize shared agent infrastructure, but the available information is too broad to name a more specific problem it solves.

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

vilona 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 7d 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.

When to Use

Trigger phrases: Trigger phrases:

  • "vilona"
  • "Help me with vilona"

Use cases:

  • When the task matches this skill's domain expertise

When NOT to use:

  • For tasks outside this skill's scope

When NOT to Use

  • When the task can be solved with existing standard libraries
  • When the infrastructure is already in place and working
  • When the added complexity does not provide measurable benefit

Overview

Vilona is a foundational core infrastructure skill that provides system foundation capabilities for the agent ecosystem.

Architecture

  • Input layer — Receives and validates incoming requests
  • Processing layer — Core logic for system foundation
  • Output layer — Formats and delivers results
  • State management — Maintains context across invocations

Configuration

  • Set up required environment variables and paths
  • Configure logging level and output format
  • Define resource limits (memory, time, API calls)
  • Enable/disable features via configuration flags

Integration

  • Exposes standard interfaces for other skills to consume
  • Supports event-driven and request-response patterns
  • Compatible with the 1ai-skills hook system
  • Logs metrics for the skill performance monitor

Money-Making Overview

Vilona's brain and entity memory system is the persistence layer that turns short-lived agent sessions into an accumulating knowledge asset. This has direct monetization value:

Opportunity Revenue Model Investment
Brain-save-as-a-service for multi-agent teams $20-50/mo per seat — persist cross-session context so agents never start blank Low (wrap existing MCP tools in a subscription tier)
Custom entity management dashboard $2K-5K build + $200/mo hosted — visual entity graph with search, drift detection, archival Medium
Memory audit & compaction consulting $500-2K per engagement — diagnose stale entity structures, optimize config, recover lost context Low
Offline-first memory sync for air-gapped deployments $5K-10K license — vilona entity protocol running on disconnected networks with periodic sync High
Agent onboarding package — entity mapping + brain rules + session hooks $1K-3K flat — set up 10-20 entities, configure brain tiers, install auto-save hooks Medium
Memory health SLA — weekly brain audits, entity compaction, drift reports $500-1K/mo recurring — automated monitoring with human-in-the-loop review Low

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.

vilona is a skill published in the GitHub repository oyi77/1ai-skills (12 stars, last pushed today), licensed MIT. It adds 18 tokens to every session and 3,998 once invoked, about $0.0001 per session on Opus 5. 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 2026-09-04.
