An architecture decision record (ADR) authoring guide for documenting options, trade-offs, the chosen option, and its reason. Decisions begin as Proposed and change status only through acceptance or later supersession.

Use it to create and manage ADRs as part of a structured software design process, including recording alternatives and preparing the decision for review.

It prevents important design choices from becoming undocumented or silently changing. It also makes rejected alternatives and the reasoning behind a decision visible.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00035	$0.00286
Opus 5.5	$0.00014	$0.00114
Sonnet 5.5	$0.00007	$0.00057
Haiku 4.5	$0.00003	$0.00029

Security

Grade A, and why

sdd-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 19d 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

SDD ADR Author

Framework skill — routes to framework/layers/05_ADR/ADR-TEMPLATE.yaml and ADR_WORKFLOW_STANDARD.md (entry gate GATE-03). Paths below use <skills-root> = this framework/skills/ directory. Upstream: BDD scenarios bound the behavior the architecture must support.

1. Decide on paper, with losers named

Each ADR names the decision, the options considered with trade-offs, and the selection with a one-line reason. An ADR with one option is a rubber stamp — find the real alternative or say why none exists. Status starts at Proposed; only acceptance moves it to Accepted (later: Deprecated or Superseded, never edited into a different past).

2. Keep the deterministic gates honest

spec_ready_status stays a binary topological verdict (PASS), not a score. Scores rot into arguments about thresholds; PASS/FAIL rot into nothing.

3. Seal and hand off

Gate: GATE-03. Fast-path restriction applies (CHG-L019). Next: sdd-spec.

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.

sdd-adr is a skill published in the GitHub repository vladm3105/aidoc-flow-framework (17 stars, last pushed 5d ago), licensed MIT. It adds 35 tokens to every session and 286 once invoked, about $0.0001 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 2026-10-26.
