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 | $0.00094 | $0.01687 |
| Opus 5.5 | $0.00038 | $0.00675 |
| Sonnet 5.5 | $0.00019 | $0.00337 |
| Haiku 4.5 | $0.00009 | $0.00169 |
Grade A, and why
prime-silo-experience 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 2mo 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 — 108 lines — stays where its author put it; the contents beside it link to each section on GitHub.
The Prime-Silo experience — identity, discovery, motion
The product is Prime-Silo. The guide who lives inside it is Agent Benny (the german
shepherd). "Space Agent" is a dead upstream name — it must never appear on a user-facing surface
(strings, titles, alt text, logos, docs prose). Identifiers (space-desktop: IPC, node space
CLI, file names, package names) are protected until Workstream H — do not rename them.
The feeling to build: walking into a quiet, beautifully organized grain silo with a very good dog showing you around. Calm by default; kinetic at the exact moments that deserve it. The marketing site (website/) already nails this — the app must feel like the same product.
1. One palette, two surfaces
All app color resolves through var(--*) tokens in
app/L0/_all/mod/_core/framework/css/colors.css (enforced by scripts/gates/c0.mjs — hex
literals outside colors.css fail the commit). The family: alabaster/cream grounds, moss/charcoal
greens for depth, rust for the ONE primary action, sage/taupe for structure. Depth = the three
--elevation-1/2/3 tokens only. Spacing/radius/measure from layout.css, type from type.css
(base ≥16px, line-height 1.5, ≤70ch, never justify). Read architecture/DESIGN-SYSTEM.md in
full before any CSS — it is short and it is law.
2. Progressive discovery (the ADHD contract, C0)
- One decision per screen. First-run, wizards, and setup flows present exactly one choice, then advance. Never a settings wall.
- One primary action per view, rust-accented, visually dominant. Everything secondary sits
behind a consistent
More ▸disclosure. - Teach by doing. Empty states offer the first action, not documentation ("Drop a PDF to begin"). After the first success, suggest exactly 3 next actions.
- Long work is honest work: always
Step n of m+ one plain line of "what happens next." Progress lands as a card, never a modal wait. - Benny narrates transitions in first person, short and warm: "I'll keep your documents on this machine." — never marketing voice inside the product.
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.

prime-silo-experience is a skill published in the GitHub repository binary16labs/prime-silo (5 stars, last pushed 13d ago), licensed MIT. It adds 94 tokens to every session and 1,687 once invoked, about $0.0004 per session on Opus 5.5. A static security scan graded it A with 0 findings.
