decide

A project decision log for recording a choice, its context, alternatives, and reasoning.

In plain words
What is it for?
Record decisions, list alternatives, link related project documentation, update project indexes, and add entries to a central log.
Why use it?
It preserves why a decision was made so the team can understand it later without repeating the same discussion.

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 2d 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.

What it actually says

/decide — Decision Logging

Record decisions with context and alternatives.

Context

Today's date: !date +%Y-%m-%d Recent decisions: !ls decisions/*/*.md 2>/dev/null | tail -10

Reference template: @_templates/decision.md Config: @_core/config.yaml Processing logic: @_core/PROCESSING.md

Input

User input: $ARGUMENTS

Processing Steps

  1. Parse Input

    • Extract project (before colon)
    • Extract decision statement
    • Look for alternatives: "over", "instead of", "vs", "considered"
    • Extract context if provided
  2. Create Decision Note

    • Filename: decisions/{project}/{date}-{slug}.md
    • Apply template with:
      • Decision statement
      • Alternatives considered
      • Context/rationale
    • Add ## Links section
  3. Auto-Link

    • Search for related docs in docs/{project}/
    • Add backlinks to relevant docs
  4. Update References

    • Add to project index if exists
  5. Append to Vault Log

    • Append entry to 01-index/_vault-log.md (see .claude/rules/vault-log.md)
    • Action: decision
    • Details: the decision statement in ~10 words

Output

Created: decisions/{project}/{date}-{slug}.md
Decision: {decision}
Alternatives: {count} considered
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.
