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

preview 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 2d 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.

How it starts

The opening of the file, as written. The whole thing — 160 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/preview — HTML Preview

Render vault content as styled HTML for browser viewing. Markdown stays the source of truth; HTML is the presentation layer.

1. Parse Input

Input pattern Action
Path to .md file Read that file directly
progress {project|all} Synthesize like /progress, use status shell
decide {slug} Glob decisions/*/*{slug}*.md, pick latest
block {slug} Glob blockers/*/*{slug}*.md
meet {slug} Glob meetings/*{slug}*.md
doc {project} {slug} Read docs/{project}/{slug}.md

If ambiguous, ask user to clarify path.

2. Gather Content

File mode: Read markdown + frontmatter.

Synthesis mode (progress): Follow /progress gather steps:

  • Scan dailies, blockers, docs, decisions for project/timeframe
  • Build structured sections: Shipped, In Progress, Blockers, Decisions
  • Count metrics for status shell

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.
