Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 2 findings, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00124 | $0.10115 |
| Opus 5 | $0.00062 | $0.05058 |
| Sonnet 5 | $0.00025 | $0.02023 |
| Haiku 4.5 | $0.00012 | $0.01012 |
Grade B, and why
local-os-builder scanned grade B 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 11d 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.

Local OS — Setup + Onboarding
USE WHEN the user runs /local-os-builder or asks to set up a Local OS, set up their vault, bootstrap the assistant, initialize the system, or configure a local Obsidian second brain.
This is the Local OS tier of the AIOS family — the brain lives in a local Obsidian vault on disk. It shares the same internal structure as the Skill OS and Cloud OS tiers, so a user can graduate between them.
This is a three-phase process:
- Phase 0: Mode Selection — Ask which OS variant to create
- Phase A: Bootstrap — Create the directory structure and system files for the selected mode
- Phase B: Onboarding — Interview the user and personalize everything
Pre-flight Check
Check if claude.md or CLAUDE.md exists only in the current working directory (do NOT search subdirectories or parent directories — check only the exact CWD path).
- If it exists: The vault is already set up. Ask the user:
- "This vault is already set up. Would you like to:"
- Re-run the interview — Keep existing structure, update memory files based on new answers
- Full reset — Delete everything and start fresh (confirm twice before proceeding)
- Cancel — Do nothing
- If it does NOT exist: Proceed with full setup (Phase 0 + Phase A + Phase B)
Phase 0: Mode Selection
Ask the user to pick a mode using AskUserQuestion with these exact label and description values:
- Question:
What type of vault do you want? - Option 1 label:
Solopreneurs/Professionals— description:Blends work and personal. Best for solo founders, freelancers, consultants. - Option 2 label:
Business/Teams— description:Org structure with departments, processes, stakeholders. Best for teams and companies.
CRITICAL: You MUST pass both label AND description for each option in AskUserQuestion. The description field is what explains each mode to the user. Never leave description empty.
Mode mapping:
- Solopreneurs/Professionals →
os-mode: professional - Business/Teams →
os-mode: business

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.
- 11d ago First seen · 747 lines · 124 tokens per session scan B e0160fc48881
local-os-builder is a skill published in the GitHub repository naveedharri/benai-skills (61 stars, last pushed 7d ago), licensed MIT. It adds 124 tokens to every session and 10,115 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
