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-authoring 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 9d 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.

MADR Authoring Skill

Canonical rules for project-level Architecture Decision Records. All ADR file mutations flow through the ADR Author subagent (.github/agents/_adr-author.md). Orchestrating workflows (system-design, plan-feature, amend-project) decide when an ADR is needed; this skill defines what the ADR must look like and how it is managed.

Scope

  • Project-level architectural decisions only.
  • Standalone Markdown files under specs/adrs/.
  • Feature-local tradeoffs stay in plan.md as AD-### rows and never invoke this skill.

Numbering and File Naming

  • Canonical identifier: ADR-NNNN — four-digit, zero-padded, repository-global.
  • File naming: specs/adrs/NNNN-decision-title.md where decision-title is lowercase ASCII kebab-case derived from the title.
  • Number allocation: scan specs/adrs/ for existing numbered files, resolve the highest allocated NNNN, assign the next integer. Numbers are monotonic and never reused.
  • Path stability: once created, a file path must not be renamed solely because the title wording changes. Title corrections stay in the body/frontmatter; the original slug persists.
  • Compatibility: readers should accept legacy three-digit references (ADR-001) but all new output must use four-digit form (ADR-0001).

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.
