record-decision

record-decision is a skill for Claude Code, Codex from leifericf/agentic-sdk. It costs 21 tokens per session (571 once invoked), scanned A, original, MIT.

A workflow for recording important architecture choices in ADRs, short documents explaining a decision, its context, consequences, and alternatives. It records choices when one option is selected over a reasonable alternative.

In plain words
What is it for?
Use it to create a numbered ADR when an architecture decision is settled, including the context, decision, consequences, and rejected alternatives.
Why use it?
It preserves why a lasting technical decision was made so future work does not have to reconstruct 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

record-decision 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 4d 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 — 62 lines — stays where its author put it; the contents beside it link to each section on GitHub.

record-decision

Architecture decisions are ADRs, written when the decision happens, not reconstructed later. Store and format come from the descriptor (:adr; default docs/adr/, nygard). Fields and voice are fixed in the "Decision records" section of references/prose-style.md.

Procedure

  1. Decide whether to record. Record when a discussion ends in "do X, not Y" and X constrains future work, or when your work settles a real choice where the rejected option was reasonable, or when you reject a review finding as deliberate and no record covers it. Do not record choices with one reasonable option, reversible implementation details, or anything an existing ADR covers (supersede it instead if the answer changed).

  2. Next number. Read docs/adr/README.md (create it as [] if missing), take the highest number, add one, two digits. The first ADR is 01.

  3. Write docs/adr/NN-slug.md:

    # ADR NN: <the decision, readable in the index>
    
    Date: YYYY-MM-DD
    
    ## Context
    ## Decision
    ## Consequences
    ## Alternatives
    

    One screenful (about 40 to 60 lines). Context is neutral, no foreshadowing. Decision is one paragraph, present tense. Consequences include the costs. Alternatives get their real strengths before the rejection. Superseding: say "Supersedes ADR NN" in the Decision; never edit the old record.

  4. Add the one-line row to the docs/adr/README.md index.

  5. Route the rule too. If the decision changes how code is written (a banned idiom, a new constraint), add the rule to the right reference or skill. The ADR holds the why; the reference holds the how. Cross-cite.

  6. Commit. Docs: Record ADR NN, <short title> (or fold into the change's commit series when recorded mid-change).

Boundaries

Owns the why of an architecture decision. The enforced how lives in a reference or lint rule, routed in step 5. Bulk promotion of captured guidance is incorporate-feedback. Does not record reversible implementation details or one-option choices.

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.
