adr-writing

adr-writing is a skill for Claude Code, Codex from Kaddo-kdd/kaddo. It costs 44 tokens per session (533 once invoked), scanned A, original, MIT.

A structured way to write Architecture Decision Records (ADRs), which are short records of important technical choices and their reasoning. It saves each record with the same sections and status values.

In plain words
What is it for?
Use it when making or recognizing a consequential architecture decision. It creates a draft or completed ADR containing the context, options, decision, consequences, and related work.
Why use it?
It prevents important decisions from being recorded inconsistently or becoming hard to audit later. It also keeps separate decisions from being mixed together and leaves unresolved choices for human confirmation.

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-writing 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 yesterday.

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.

ADR Writing Skill

Purpose

Standardize how Architecture Decision Records are written so every decision is captured the same way and stays auditable.

When to use

When a real, consequential technical decision is being made or recognized — and only then.

Inputs

The context pack, the relevant Work Item or architecture note, and the decision being made.

Output

A single ADR (saved under knowledge/tech/decisions/) with front matter and the standard sections: context, options considered, the decision, consequences, related capabilities and related Work Items. Status is one of draft, accepted, superseded, deprecated.

Materializing from decision candidates (VS-075)

When knowledge/tech/decisions/ is empty but knowledge/tech/decision-candidates.md holds candidates, materialize each candidate as an ADR draft — copy its context and options, leave the decision and consequences as [open] for human confirmation, and record its origin with created_from: knowledge/tech/decision-candidates.md. Never mark a materialized draft accepted; acceptance is a human decision.

Rules

  • One ADR = one decision. Never mix unrelated decisions.
  • Never invent decisions; never write an ADR without a clear reason.
  • Record alternatives honestly, including the one chosen and why (or [open] when undecided).
  • Prefer narrow governed code: globs over broad ones.

Quality checklist

  • Context explains why the decision was needed.
  • The decision and its alternatives are explicit (or explicitly [open]).
  • Consequences (positive and negative) are stated.
  • Status and governed paths are present.

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.

adr-writing is a skill published in the GitHub repository Kaddo-kdd/kaddo (54 stars, last pushed today), licensed MIT. It adds 44 tokens to every session and 533 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-25.
