It turns an uncertain choice into a documented comparison aligned with current goals.

Command for Claude Code

Written for Claude Code: $ARGUMENTS substitution.

This is vmarcondes-nilo/personal-os's own configuration. It tells Claude Code how to work on personal-os itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything personal-os configures →

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

decide 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 2mo 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.

Decision Logger

Help think through and log an important decision. This is a structured coaching conversation that ends with a saved decision record.

Topic: $ARGUMENTS


1. Read Context

Read these files for background:

  • decisions/_template.md — output format
  • Current quarter's OKR file in goals/ — decisions should align with goals
  • Relevant area file in areas/
  • Recent entries in decisions/ — to see past decisions and avoid revisiting settled ones

2. Clarify the Decision

If $ARGUMENTS is provided, use it as the starting point. Otherwise ask: "What decision are you wrestling with?"

Then clarify:

  • "What's forcing this decision now?" — understand the trigger and urgency
  • "What happens if you do nothing?" — check if it even needs deciding today
  • Area: Which life area does this touch?

Keep this tight — 2-3 questions max. Don't over-interview.

3. Map Options

Ask: "What options are you considering?"

Let the user go first, then:

  • Add options they might be missing (there's almost never just 2)
  • For each option, briefly note:
    • Upside: best realistic outcome
    • Downside: worst realistic outcome
    • Reversibility: easy to undo, or a one-way door?

4. Pressure-Test

Pick the right lens for this decision:

Strategic decisions (company, product, hiring):

  • Pre-mortem: "It's 6 months later and this failed — what went wrong?"
  • First principles: "What assumptions are baked in here?"

Resource decisions (time, money, priorities):

  • "What are you saying no to by saying yes to this?"
  • 80/20: "Which option gets 80% of the result with 20% of the effort?"

Personal decisions (family, health, lifestyle):

  • "What will you regret NOT doing?"
  • "What aligns with your values?" (reference profile/values.md)
  • "What would you tell a friend in this situation?"

Be direct. Challenge weak reasoning. Don't just validate — push back.

5. Decide

Push for a clear outcome:

  • "What are you going to do?"
  • "By when?"
  • "Who needs to know?"
  • "What's the first concrete action?"

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.
