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

architecture-decision-records 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.

What it actually says

Architecture decision records

When to write an ADR

Write ADR Skip ADR
New framework or major dependency Minor version bump
Database or storage choice Bug fix
API or integration pattern Config-only change
Security or auth architecture Routine maintenance

Lifecycle

Proposed -> Accepted -> Deprecated -> Superseded

Do not rewrite accepted ADRs; add a new ADR that supersedes the old one.

Required sections

  1. Context — problem and constraints
  2. Decision — what was chosen (one clear statement)
  3. Consequences — positive, negative, risks and mitigations
  4. Status and date
  • Decision drivers (numbered)
  • Considered options with honest pros/cons
  • Related ADRs / links

Lightweight template

Full MADR-style templates

See reference.md for extended templates (standard, Y-statement, deprecation).

Practices

  • Write before implementation starts when possible.
  • Keep ADRs short (1-2 pages); link deep dives elsewhere.
  • Be honest about trade-offs.
Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
