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 | $0.00016 | $0.00904 |
| Opus 5 | $0.00008 | $0.00452 |
| Sonnet 5 | $0.00003 | $0.00181 |
| Haiku 4.5 | $0.00002 | $0.00090 |
Grade A, and why
dakota-workstation 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 today.
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 — 71 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Dakota Workstation Integration
Dakota runs Homebrew directly on the host rather than in a container, with persistent user data at /home/linuxbrew/.linuxbrew.
When to Use
- Editing host Homebrew packaging elements (
elements/bluefin/brew.bst,brew-tarball.bst) - Managing workstation services or systemd unit presets owned by BST elements and their source files
- Diagnosing broken host brew prefixes or bottle rejection errors (see
references/host-homebrew.md)
When NOT to Use
- Packaging system applications or CLI tools for the base image → load
dakota-packaging - Writing end-user ujust recipes → load
dakota-ujust - OCI layer composition → load
dakota-image
Core Process
- Route the Area:
- Host Homebrew integration or prefix issues: consult
references/host-homebrew.md. - Workstation services / systemd units: locate the owning BST element and its
sources/install-commands. Unit files are distributed under directories such asfiles/firstboot/,files/countme/, andfiles/wallpaper-month/; some units and presets are generated by elements. Usefind files -type f \( -name '*.service' -o -name '*.timer' -o -name '*.preset' \)to locate source files, then trace their callers inelements/.
- Host Homebrew integration or prefix issues: consult
- Verify State Boundaries:
- Differentiate image-owned immutable files (
/usr) from persistent user state (/home/linuxbrew).
- Differentiate image-owned immutable files (
- Declare Services in BST:
- Enable units declaratively in BST element
install-commandsor via systemd preset files.
- Enable units declaratively in BST element
- Validate:
- Run
just validateto ensure dependency graphs and layer composition remain sound.
- Run
Invariants
- Prefix Spelling Invariant: Invoke brew strictly through
/home/linuxbrew/.linuxbrew/bin/brew. The/var/homespelling breaks bottle prefix detection and forces broken source builds. - GNU Make Invariant: The image must supply GNU Make in
/usr/binalongside GCC. Homebrew's internal PATH filter strips all other locations during native gem builds. - Persistent State Invariant:
/home/linuxbrew/.linuxbrewis persistent user data. Reboots and image updates will not repair corrupted gems. - No ublue-os Writes: Fix shared path regressions in
projectbluefin/common. Never submit PRs or issues toublue-os/*.
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.
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.

dakota-workstation is a skill published in the GitHub repository projectbluefin/dakota (150 stars, last pushed today), licensed MIT. It adds 16 tokens to every session and 904 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 2026-08-30.
