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 | $0.00046 | $0.00592 |
| Opus 5 | $0.00023 | $0.00296 |
| Sonnet 5 | $0.00009 | $0.00118 |
| Haiku 4.5 | $0.00005 | $0.00059 |
Grade A, and why
design-docs-page 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 6d 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.
This is a copy
92% identical to docs-page — 24 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 54 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Docs Page Skill
Produce a single, three-column documentation page in one HTML file.
Workflow
- Read the active DESIGN.md (injected above). Use the body type token for prose; the mono token for code; respect line-height and max-width rules.
- Pick a topic from the brief — the page should look like real docs, not a generic wireframe. Concrete API names, command examples, plausible parameters.
- Lay out three regions:
- Left nav (240–280px, sticky): grouped link list, current page bolded with a left-edge accent stripe. 3–5 groups of 4–8 links.
- Article body (max-width ~720px, centered in the middle column): H1, lede paragraph, H2 sections, code blocks, callout boxes (note / warning), inline links, lists.
- Right TOC (200–240px, sticky): "On this page" with the H2/H3 anchors, current section highlighted as the user scrolls.
- Write a single HTML document:
<!doctype html>through</html>, all CSS inline.- CSS Grid for the three columns; sticky positioning for the rails.
- Code blocks: monospace token, soft surface fill, copy-button affordance (visual only — no JS needed).
- Anchor IDs on every H2/H3 so the TOC links work.
data-od-idon the nav, article, and TOC.
- Prose: write at least 350 words of believable docs. Include at least one shell command, one code snippet (5–15 lines), one callout, one table.
- Self-check:
- Body text wraps at the DS line-length sweet spot (60–75 chars).
- Code uses the DS mono token, not generic
monospace. - Accent is restrained — used for active nav item, links, one callout border. Not on body text.
- Page is readable at 1280w and collapses gracefully below 900w (TOC drops out, nav becomes a top drawer).
Output contract
Emit between <artifact> tags:
<artifact identifier="docs-slug" type="text/html" title="Docs — Page Title">
<!doctype html>
<html>...</html>
</artifact>
One sentence before the artifact, nothing after.
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.

design-docs-page is a skill published in the GitHub repository the-sid-dani/second-brain-os (2 stars, last pushed 1mo ago), licensed MIT. It adds 46 tokens to every session and 592 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. It is 92% identical to docs-page, differing in 24 lines, and is treated as a copy.
