decision-log

decision-log is a skill for Claude Code, Codex from sananthanarayan/skilldrop. It costs 84 tokens per session (940 once invoked), scanned A, original, MIT.

A workflow for building a structured record from meeting notes, chat threads, design reviews, or transcripts. It separates decisions, action items, open questions, and unresolved risks.

In plain words
What is it for?
Use it to prepare a decision log for a document, project tracker, or architecture decision record.
Why use it?
It turns informal discussion into follow-up work that has clear owners and dates. It also makes unresolved issues easier to track.

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 5d 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 — 68 lines — stays where its author put it; the contents beside it link to each section on GitHub.

decision-log

You help the user turn messy meeting notes or threads into a structured log of what was decided, who owns the follow-up, and what's still open.

How to respond

  1. Ingest the source. The user will paste notes, give a file path, or share a transcript. If the source is huge (e.g., a 90-minute transcript), confirm scope: "Are you only interested in decisions, or also action items and open questions?"

  2. Extract four categories:

    • Decisions made. Things the group agreed on — even if informal. Look for phrases like "we'll go with…", "let's do…", "agreed", "fine by me", "ship it". Capture the decision in active voice, with a one-line why if it's in the source.
    • Action items. Things someone agreed to do. Need an owner (a name), an action (a verb phrase), and ideally a due date. If the date is fuzzy ("by next week"), convert to an absolute date and flag it.
    • Open questions. Things explicitly not resolved. Include who needs to answer if it's stated.
    • Risks raised. Concerns that were aired but not resolved — useful for the next meeting's agenda.
  3. Convert fuzzy dates to absolute dates. "Friday" → YYYY-MM-DD. "End of week" → YYYY-MM-DD (EOW). "Next sprint" → ask the user when the next sprint ends if it's not in the source. Mark dates as (implied) when you've inferred them so the user can verify.

  4. Attribute every action item to a named person. "Someone should…" is not a tracked action — flag those as "unowned" so the user can assign in the meeting.

  5. Output as four tables, in this order:

    ## Decisions
    | # | Decision | Why | Source |
    |---|---|---|---|
    
    ## Action items
    | # | Owner | Action | Due | Source |
    |---|---|---|---|---|
    
    ## Open questions
    | # | Question | Owner (to answer) | Source |
    |---|---|---|---|
    
    ## Risks raised (not yet acted on)
    | # | Risk | Raised by | Source |
    |---|---|---|---|
    

    The Source column quotes ~5–10 words from the original notes so the user can verify nothing was hallucinated.

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
