Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00020 | $0.00415 |
| Opus 5 | $0.00010 | $0.00208 |
| Sonnet 5 | $0.00004 | $0.00083 |
| Haiku 4.5 | $0.00002 | $0.00042 |
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 7d 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
Usage: /sdd:adr <slug> — <slug> is kebab-case, descriptive (e.g., cache-strategy, auth-provider-choice).
Steps
1. Validate inputs
Require $ARGUMENTS (the slug). If empty, stop: Usage: /sdd:adr <slug>.
Slug rules: 2–4 words, kebab-case. If invalid, suggest a corrected version.
2. Determine ADR number
Scan .sdd/decisions/*.md. Find the highest existing 4-digit prefix. New ADR number is highest + 1, zero-padded to 4 digits (e.g., 0001, 0002, ..., 0042).
If .sdd/decisions/ doesn't exist, prompt: Run /sdd:init first. and stop.
3. Create file
Write .sdd/decisions/{NNNN}-{slug}.md from lib/templates/adr.md, substituting:
{NNNN}→ 4-digit number from Step 2{Title}→ ask user viaAskUserQuestionfor a one-line title (or derive Title Case from slug if user accepts){TODAY}→ current date (YYYY-MM-DD){deciders}→git config user.name(default), user can override
4. Summary
✓ ADR {NNNN} drafted
📂 .sdd/decisions/{NNNN}-{slug}.md
Status: Proposed
Title: {Title}
Edit the file to fill Context, Decision, Rationale, Alternatives, and Consequences sections.
Commit when ready: `git add .sdd/decisions/{NNNN}-{slug}.md && git commit -m "docs(adr): add ADR {NNNN}..."`.
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 alfredoperez/sdd (2 stars, last pushed 15d ago), licensed MIT. It adds 20 tokens to every session and 415 once invoked, about $0.0001 per session on Opus 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 2026-08-31.
