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

Telos scanned grade A with 1 finding 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 1mo ago.

The scan reads SKILL.md. This mod also ships 18 executable files (DashboardTemplate/app/api/chat/route.ts, DashboardTemplate/app/api/file/get/route.ts, DashboardTemplate/app/api/file/save/route.ts, …), 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.

How it starts

The opening of the file, as written. The whole thing — 343 lines — stays where its author put it; the contents beside it link to each section on GitHub.

🚨 MANDATORY: Voice Notification (REQUIRED BEFORE ANY ACTION)

You MUST send this notification BEFORE doing anything else when this skill is invoked.

  1. Send voice notification:

    curl -s -X POST http://localhost:31337/notify \
      -H "Content-Type: application/json" \
      -d '{"message": "Running the WORKFLOWNAME workflow in the Telos skill to ACTION"}' \
      > /dev/null 2>&1 &
    
  2. Output text notification:

    Running the **WorkflowName** workflow in the **Telos** skill to ACTION...
    

This is not optional. Execute this curl command immediately upon skill invocation.

Telos

What It Does

Reads and updates two kinds of context. Personal TELOS: the principal's life context — goals, beliefs, wisdom, books, movies, challenges, narratives, strategies, mission, models, predictions, traumas, frames, lessons, wrong-beliefs — at ~/.claude/LIFEOS/USER/TELOS/, updated through the Update workflow with timestamped backups. Project TELOS: analyzes a directory of .md/.csv files to extract dependency chains (PROBLEMS→GOALS→STRATEGIES→PROJECTS), bottlenecks, alignment, and progress, then produces a McKinsey-style report, n=24 narrative points, or a Next.js dashboard built by parallel engineers.

The Problem

Life context and project state both sprawl across many files, and acting on them by hand is error-prone. Personal goals, beliefs, and lessons drift out of date, and hand-editing them risks losing history or corrupting structure. Project documentation hides the dependency chains, bottlenecks, and misalignments that decide whether the work is on track — you can read every file and still not see how PROBLEMS connect to GOALS connect to PROJECTS. This skill gives both a single safe way in: structured updates with backups for the personal side, and automated relationship analysis plus rendered outputs for the project side.

How It Works

TELOS (Telic Evolution and Life Operating System) is a context-gathering system with two applications:

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.
