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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00035 | $0.00902 |
| Opus 5.5 | $0.00014 | $0.00361 |
| Sonnet 5.5 | $0.00007 | $0.00180 |
| Haiku 4.5 | $0.00003 | $0.00090 |
Grade A, and why
formax-web-css-convergence-workflow 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.

Goal
- Prevent repeated CSS rework by locking requirements before any style edits.
- Convert ambiguous visual requests into a concrete edit contract with explicit acceptance checks.
- Keep behavior stable while converging structure, naming, and styling.
Use this skill when the task involves:
- component styling or layout adjustments
- cross-file CSS + TSX class changes
- interaction visual states (hover/active/focus/selected)
- repeated back-and-forth UI tuning that needs convergence
Intake Contract (Run Before Editing)
- Require this 8-line input contract (fill missing items by explicit assumptions, not guesswork):
- Target model in one sentence (final visual geometry).
- Non-goals / do-not-touch list.
- State model (if any) and single source of truth.
- Ownership boundary (main process vs renderer).
- Acceptance criteria (what must be true, what must never appear).
- Runtime matrix (command, platform, light/dark).
- Iteration policy (single-axis change per pass).
- Rollback point (which commit/file set is safe fallback).
Where to change what
- Core styling surfaces:
packages/web-reference-react/src/styles.csspackages/web-reference-react/src/css/theme.css
- Core UI wiring:
packages/web-reference-react/src/app/ui/AppShell.tsxpackages/web-reference-react/src/components/LeftRail.tsxpackages/web-reference-react/src/components/left-rail/SidebarItem.tsx
- Browser bridge typing surface (when needed):
packages/web-reference-react/src/vite-env.d.ts
- Desktop main/preload ownership (only for stateful window-level visuals):
packages/desktop-electron/src/main.tspackages/desktop-electron/src/preload.tspackages/desktop-electron/src/windowAppearanceState.ts
- Scenario-specific construct (read only if task touches transparency):
docs/contracts/web/window-transparency-construct.md
Patterns
- Freeze-Then-Edit Pattern
- Restate final model first.
- Freeze non-goals (do not touch drag region, menu entries, unrelated text/copy).
- Only then open code.
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.
