adr

adr is a skill for Claude Code from andregusman-raiz/a-gusman-claude. It costs 42 tokens per session (1,292 once invoked), scanned A, original, MIT.

A skill for writing an Architecture Decision Record (ADR), a short document that records why a technical choice was made, including alternatives and trade-offs.

In plain words
What is it for?
Use it when choosing technology, recording an architectural decision, or documenting trade-offs. It creates numbered Markdown records in the project’s docs/adr directory.
Why use it?
It preserves the reasoning behind architecture decisions so future developers can understand the choice instead of revisiting the same debate. It also standardizes where ADR files are stored and how they are numbered.

    Skill selects an external model or provider that may use a different account or billing plan than the operator expects. Undisclosed model switches can cause unexpected cost or quota consumption.
    Fix: Remove the model/provider override or disclose it prominently and require explicit operator approval before invoking an external coding CLI or billed model.

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

adr 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 12d 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.
