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

vkr-building 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 10d 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 — 100 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Running the build

Call the launcher, not main.py — it finds Python and names itself in the tool's own hints:

vkr-builder.bat build          # Windows
./vkr-builder.sh build         # Linux/macOS
python main.py build           # only if the launchers cannot be used

build is the default command, so bare vkr-builder.bat builds too.

Commands

Command What it does
build merge → lint → document (+ --pdf)
merge only produce the bundle
docx build from an existing bundle
pdf [docx] convert a DOCX to PDF
preview <file.md> build one file, no TOC, next to the source
lint / stats / validate checks and numbers, no document
diagnose <docx> quality report on a finished document
watch rebuild on change (needs watchdog)
doctor what is installed and which engine would be used
init / profiles / help config template, profile list, usage

Useful flags: --profile NAME, --pdf, --pagination-engine {auto,word,libreoffice}, --skip-merge, --skip-docx, --no-preflight, --diagnose.

Engines

pagination_engine: auto is the default: Word if it is installed (more accurate for GOST layout), otherwise LibreOffice. The header says which one was chosen — word engine (auto). Run doctor before blaming a build:

    ✓ word         Word 16
    ✓ libreoffice  /usr/bin/soffice
    ✓ pagination   auto → word · Word 16

A missing engine is a warning there (one of the two is enough); "no layout engine available" is a command failure.

  • Steps carry facts and timings; the footer carries the outcome, the counts and the files produced.
  • Findings name the source file and line, not the merged bundle.
  • · N suppressed means an @suppress directive silenced something on purpose. Do not report a run as clean if that number is non-zero.
  • Verbosity: -v adds per-step notes, --debug adds the Word/LibreOffice trace, -q prints errors only.

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.
