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.

SkillSpector: 2 findings, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- high Privilege Escalation · line 402 Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.Fix: Remove references to credential paths. Use environment variables or secrets managers. For docs, use placeholder paths (e.g., /path/to/config). Never load .env or token files in production code paths.
- medium Excessive Agency · line 438 Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.
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 | $0.00050 | $0.03937 |
| Opus 5.5 | $0.00020 | $0.01575 |
| Sonnet 5.5 | $0.00010 | $0.00787 |
| Haiku 4.5 | $0.00005 | $0.00394 |
Grade A, and why
new-deno-app scanned grade A with 1 finding 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 1mo 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.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.
self.addEventListener("fetch", (e) => e.respondWith(fetch(e.request))) How it starts
The opening of the file, as written. The whole thing — 484 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are scaffolding a new personal web app. These apps follow a strict set of conventions:
- Deno 2 runtime, no build step — TypeScript runs natively
- Hono for routing (from JSR:
jsr:@hono/hono@^4) - Deno KV for the database (built-in to Deno)
- Eta for server-side HTML templates (from JSR:
jsr:@eta-dev/eta@^3) - HTMX 2 for frontend interactivity (CDN, no npm)
- PicoCSS classless for styling (CDN, no npm)
- Single shared
APP_PASSWORDenv var for auth — SHA-256 hash in a session cookie - PWA:
manifest.json+ minimal pass-through service worker - Deployed to Deno Deploy via GitHub push to
main
Step 1: Gather information
Always ask the user for all of the following interactively — do not attempt to parse $ARGUMENTS:
- app-name — kebab-case, used for directory name and GitHub repo name
- Display Name — full title shown in browser tab and manifest (e.g. "Book Tracker")
- Short name — ≤12 characters, shown on Android home screen under the icon (e.g. "Books")
- Description — one sentence describing what the app does
- Theme color — hex color for PWA theme/background (default:
#ffffff) - Emoji — single emoji used as the app logo in the header (default:
📋) - Data model — what are the main things this app stores? Describe the entity name(s) and their fields briefly.
Confirm all values with the user before proceeding.
Step 2: Determine project directory
Check whether the current working directory is empty (contains no files or subdirectories, ignoring dotfiles like .git).
- If the current directory is empty: use it as the project root. All files will be created here.
- If the current directory is not empty: tell the user: "The current directory isn't empty. Please create and switch to a new empty directory for the project, then run
/new-deno-appagain." Stop here — do not proceed.
Step 3: Create project
Create all files in the project root determined in Step 2. All files below use the exact patterns from the reference app.
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.
- 1mo ago First seen · 484 lines · 50 tokens per session scan A 9da0a414724b
new-deno-app is a skill published in the GitHub repository jackfranklin/dotfiles (254 stars, last pushed 6d ago), licensed MIT. It adds 50 tokens to every session and 3,937 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
