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 | $0.00048 | $0.00796 |
| Opus 5 | $0.00024 | $0.00398 |
| Sonnet 5 | $0.00010 | $0.00159 |
| Haiku 4.5 | $0.00005 | $0.00080 |
Grade A, and why
inkwell-retrofit 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 — 80 lines — stays where its author put it; the contents beside it link to each section on GitHub.
inkwell-retrofit
Use this skill when an existing page, component, or standalone document needs to adopt Inkwell while preserving its content and behavior.
Good fits
- Re-skin an existing page with Inkwell tokens and primitives.
- Convert a standalone HTML explainer or report to the Inkwell visual system.
- Remove duplicate token declarations or competing CSS shims.
- Align a Tailwind v4 project with Inkwell's token and theme model.
Do not use this skill to redesign the product information architecture or rewrite content. The default move is visual alignment, not content invention.
First read
Before editing, read:
AGENTS.mdfor project-specific styling rules.- Existing Inkwell files under
app/css/andpublic/css/. - Any sibling page already using Inkwell, such as a report or explainer.
- The target page/component end to end so content stays intact.
Core rules
- Reuse existing Inkwell tokens before adding project-specific tokens.
- Do not hardcode hex colors outside token definitions.
- Prefer semantic tokens such as
--ivory,--paper,--slate,--accent,--border, and--backdrop. - Keep one saturated accent unless the page truly needs data-viz hues.
- Use Inkwell primitives where available:
.card,.alert,.tbl,.tldr,.toc,.sec-head,.eyebrow,.badge,.chip-dot. - Preserve the 1.5px hairline convention unless the project explicitly documents a different value.
- Keep typography roles consistent: serif for major headings and editorial callouts, mono for labels/file refs/code, sans for normal body UI.
- Preserve dark-mode behavior through
data-themeand tokens, not per-component ad hoc overrides. - SVG fills and strokes should reference tokens so diagrams theme correctly.
Retrofit steps
- Identify the current styling source: global CSS, inline styles, Tailwind utilities, standalone
<style>, or linked CSS. - Remove competing token systems only when Inkwell fully replaces them.
- Map existing colors, borders, typography, spacing, and callouts to Inkwell tokens and primitives.
- Keep app-specific extensions small, named, and layered after Inkwell imports.
- Replace hardcoded rgba/hex values with semantic tokens.
- Preserve content and IDs unless the task explicitly asks for content edits.
- Verify light and dark modes.
- Verify the page renders standalone if it was standalone before.
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.

inkwell-retrofit is a skill published in the GitHub repository vscarpenter/gsd-task-manager (25 stars, last pushed yesterday), licensed MIT. It adds 48 tokens to every session and 796 once invoked, about $0.0002 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.
