decision-log is a skill for Claude Code from berkcangumusisik/agent-hub. It costs 53 tokens per session (338 once invoked), scanned A, original, MIT.

A lightweight architectural decision record, or ADR, system for saving and reading important project choices.

In plain words
What is it for?
Use it to record accepted decisions with their context, alternatives, and consequences, or read earlier decisions when planning changes.
Why use it?
It preserves why a technical decision was made, so future work can follow the same choice instead of reopening the 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

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 10d 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

decision-log

Maintain a lightweight ADR log at .claude/agent-hub/decisions/ — the team's memory.

Recording a decision

  1. Create .claude/agent-hub/decisions/ if it doesn't exist.
  2. Find the next number: count existing NNNN-*.md files and increment (start at 0001).
  3. Write .claude/agent-hub/decisions/NNNN-<kebab-title>.md with these sections:
    • Title, Status (Accepted), Date (absolute, e.g. 2026-06-26), Deciders
    • Context — the problem and forces at play
    • Decision — what was chosen
    • Alternatives considered — each option and why not
    • Consequences — trade-offs, what gets easier/harder Keep it short and concrete.
  4. Confirm the saved path back to the user.

Reading decisions

When orienting to a project (or asked "why did we do X"), read the files under .claude/agent-hub/decisions/ and honor them — do not silently contradict an accepted decision. If new work conflicts with one, flag it and propose superseding the ADR.

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.
