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 | $0.00051 | $0.00922 |
| Opus 5 | $0.00026 | $0.00461 |
| Sonnet 5 | $0.00010 | $0.00184 |
| Haiku 4.5 | $0.00005 | $0.00092 |
Grade A, and why
ds-polish 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 2d 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.

The opening of the file, as written. The whole thing — 119 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Preamble
"../lib/env.sh" "polish"
What this skill does
Think of this as the final check before you hit publish. I'll look at your site through 11 different lenses — from "does it look good?" to "can everyone use it?" — and tell you exactly what to fix before sharing with the world.
This is the release gate. If the user only wants one-screen visual QA, route them to /ds-look. If they want cross-page brand consistency, route them to /ds-brand.
Takes about 3–5 minutes.
"Checking 11 areas before you share this. Takes 3–5 minutes. I'll tell you what needs fixing and what's already great."
Step 1 — Get the URL
Ask:
"What's the main page you want to polish before sharing? (e.g.
http://localhost:3000or your live site)."
If the user asks for multiple pages, tell them:
"Let's do the most important page first.
/ds-polishis the final release gate for one page at a time. If you want a multi-page consistency scan, use/ds-brand."
Step 2 — Load context
If DESIGN_BIBLE is yes, read it for brand rules.
Note from Memory Log any recent confirmed intentional changes.
Step 3 — Run all 11 checks
For each check, take a screenshot and extract what you need. Describe findings in plain English.
Read references/checklist.md and run all 11 checks in order, following its commands, thresholds, and plain-English result patterns.
Step 4 — Write the polished report
Follow the jargon rules in lib/plain-language.md when writing this report — no technical terms.
Pre-launch check for [URL]
Overall: [Ready to share / A few things to fix / Needs work before launch]
Score: [X]/11 checks passed
✓ Already great: [List checks that passed — give credit for what's working]
⚠️ Fix before sharing:
[For each failed check:] [Check name] — [Plain English description of the issue] How to fix: [Specific plain-English fix] How long: [Quick (1 min) / Short (5-10 min) / Takes a while]
My top 3 fixes (do these now):
- [Most visible or impactful issue]
- [Second most important]
- [Third]
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.
