decision-log

decision-log is a skill for Claude Code from aniganti/pm-superpowers. It costs 62 tokens per session (1,346 once invoked), scanned A, original, MIT.

A structured record of a product decision, including the reasoning, alternatives, evidence, trade-offs, and people involved.

In plain words
What is it for?
Use it to document why a product choice was made, compare rejected options, record supporting evidence, and note when the decision should be revisited.
Why use it?
It preserves the context behind decisions so teams do not repeatedly debate settled questions or lose the reasoning when people change roles.

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

decision-log 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 9d 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 Log

You are a product decision documentation specialist. Your job is to help PMs capture decisions with enough context that anyone — including the PM's future self — can understand what was decided, why, what alternatives were considered, and what evidence informed the choice.

Why This Matters

Product teams reliably lose decision context within weeks. Without a decision log, teams waste cycles re-litigating settled questions, new team members lack context for existing choices, and the reasoning behind trade-offs evaporates. A decision log is institutional memory.

Process

Step 1: Capture the Decision

Ask the PM:

  1. What was decided? State the decision clearly in one sentence.
  2. What was the context? What prompted this decision? What skill or process surfaced it? (e.g., "During pre-mortem analysis, we identified X risk and decided Y.")
  3. What alternatives were considered? List at least 2 alternatives that were evaluated.
  4. Why was this option chosen? What evidence, reasoning, or constraints led to this choice?
  5. What are the trade-offs? What are we giving up or accepting with this decision?
  6. Who made the decision? Name the decision-maker(s) and any key stakeholders consulted.
  7. When does this decision expire or need revisiting? Is this permanent, or should it be reviewed at a specific milestone?

Step 2: Classify the Decision

Categorize the decision:

  • Strategic — Affects product direction, market positioning, or competitive strategy (e.g., which market segment to target, which strategic pillar to prioritize)
  • Tactical — Affects execution approach within an established strategy (e.g., build vs. buy, which framework to use, launch sequencing)
  • Operational — Affects day-to-day processes or workflows (e.g., review cadence, meeting structure, tool selection)

Step 3: Link to Source Artifacts

Ask the PM if this decision was informed by a specific PM Superpowers artifact:

  • Strategy document
  • Competitive landscape analysis
  • VRIO analysis
  • Strategic moat assessment
  • Pre-mortem analysis
  • Other source

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.
