Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00157 | $0.01738 |
| Opus 5 | $0.00078 | $0.00869 |
| Sonnet 5 | $0.00031 | $0.00348 |
| Haiku 4.5 | $0.00016 | $0.00174 |
Grade A, and why
flexible-visual-system 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 — 169 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Flexible Visual System
Generate raw SVG from rules, not by hand-drawing. One small rule set produces a coherent family of infinite variations.
Based on Martin Lorenz (new.twopoints.net/fvs), Flexible Visual Systems: design the system, not the output. Fixed rules + variable inputs = consistent identity that flexes.
Flow: intake -> sweep -> tune -> lock -> export. Intake derives rules from the project; the rest explores on top of them.
Core idea
A visual system is f(rules, seed) -> SVG.
- The rules stay fixed (that is what makes the family coherent).
- The seed / inputs vary (that is what makes each output distinct).
- You explore by sweeping inputs in a playground, then lock the ones worth keeping as design-system assets.
Do not draw a logo. Build the machine that draws thousands of valid logos, then pick.
Intake: deriving rules from a project
The playground needs rules to sweep. Intake gets them from the project, not from thin air. Run it before any sweep.
Scan -> Map -> Bootstrap -> Lock.
- Scan - read the project's existing tokens, palette, type scale, logo, icons, base grid. A handful of anchors is enough; do not audit exhaustively.
- Map - translate findings onto the six primitives (palette -> Color, logo symmetry -> Transformation quantization, container grid -> Grid cols, stroke weight -> Module weight, etc.).
- Bootstrap - if scan finds nothing usable: a short guided interview
(mood, 2 anchor colors, one motif, structure, do/don't, optional
reference), then propose one minimal starter rule set with a
whyper rule. Not three to pick from - one, derived from what they said. - Lock - write the chosen rules to the project's rules file so future runs read it first instead of re-deriving.
Read references/intake.md for the scan checklist, the finding-to-primitive
map, the interview questions, and the bootstrap-to-lock handoff.
The rules file (project source of truth)
The locked rules live in visual-system.md at the project root. The skill
reads it before every generate/sweep/export, and writes back when a rule
changes or a keeper is locked.
What ships with it
6 files 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.

flexible-visual-system is a skill published in the GitHub repository scott-fryxell/brayness (120 stars, last pushed yesterday), licensed MIT. It adds 157 tokens to every session and 1,738 once invoked, about $0.0008 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.
