decide

decide is a skill for Claude Code from Aiyo28/memento-os. It costs 92 tokens per session (1,152 once invoked), scanned A, original, MIT.

A decision-making guide that compares options, checks confidence, and records the reasoning. It can also study a source first or deliberately look at the problem from another angle.

In plain words
What is it for?
Use it when choosing between options, researching a document or link before deciding, or looking for assumptions and perspectives you may have missed.
Why use it?
It gives decisions a repeatable process and leaves a record of why a choice was made. This helps separate useful research from material that does not affect the decision.

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 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.

How it starts

The opening of the file, as written. The whole thing — 127 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/decide

One skill. Three modes. Every decision produces a reasoning artifact with a priority level.

Setup

The vault path is configured during memento init. If not set, ask the user where their vault lives.

Mode Detection

Signal Mode What happens
Decision needed from current context default Jump to OODA loop
URL, file, or "research this" provided --research Ingest source → extract → then OODA loop
"reframe", "different angle", "what am I missing" --reframe Force perspective shift → then OODA loop

Mode: --research (Ingest First)

Extract knowledge from the source before deciding.

Extraction Engine (5 Fields)

  1. Core argument — what it argues, not what it's about (1-2 sentences)
  2. Why it holds — evidence, reasoning, mechanism (3 bullets max)
  3. Technical specifics — numbers, code patterns, tools. "None" if none
  4. Execution pattern — the craft move worth stealing. Omit if N/A
  5. Open questions — what connects to existing work? What assumption might break?

After extraction, ask: "Does this inform a decision, or is it reference material?"

  • Decision → continue to OODA loop
  • Reference only → save to project Research/ folder, stop

Mode: --reframe

Force a perspective shift before presenting options:

  1. Invert the question — "What if we did the opposite?"
  2. Change the timeframe — "What matters in 6 months vs today?"
  3. Change the stakeholder — "What would the end user prioritize?"
  4. Expose assumptions — "What are we assuming that might not be true?"

Then enter the OODA loop with the expanded frame.

Retrieval Gate

Before presenting options, search the vault for prior decisions on this topic:

  1. Scan project _context.md Active Reasoning Artifacts table for [D] entries matching the decision domain
  2. Glob {vault_path}/Knowledge/*{topic}* for existing knowledge notes
  3. Glob {vault_path}/Projects/*/Decisions/*{topic}* for cross-project decisions
  4. If prior decision found:
    • Surface it: "Existing decision: [D] {statement} — {date}"
    • Ask: "Reaffirm, revise, or override?"
  5. If no prior decision: proceed with fresh analysis

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 skill published in the GitHub repository Aiyo28/memento-os (3 stars, last pushed 2d ago), licensed MIT. It adds 92 tokens to every session and 1,152 once invoked, about $0.0005 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 2026-08-31.
