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 | $0.00000 | $0.00637 |
| Opus 5.5 | $0.00000 | $0.00255 |
| Sonnet 5.5 | $0.00000 | $0.00127 |
| Haiku 4.5 | $0.00000 | $0.00064 |
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.
How it starts
The opening of the file, as written. The whole thing — 78 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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.

decide is a command published in the GitHub repository vmarcondes-nilo/personal-os (46 stars, last pushed 7mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 637 tokens. 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 2026-08-30.
