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 5.1 | $0.00116 | $0.03124 |
| Opus 5.5 | $0.00046 | $0.01250 |
| Sonnet 5.5 | $0.00023 | $0.00625 |
| Haiku 4.5 | $0.00012 | $0.00312 |
Grade C, and why
netlify-deploy scanned grade C 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 17d 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.
Hidden instructionshighPrompt injection
Directives inside HTML comments, invisible characters or bidirectional overrides are read by the model and not by the person reviewing the file.

The opening of the file, as written. The whole thing — 192 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Netlify deploy
Modern CLI
netlify deploy # manual draft deploy (no CI)
netlify deploy --prod # deploy straight to production
netlify create # new project from a natural-language prompt
netlify deploy --allow-anonymous # temp project, claim within 1 hour
npm update -g netlify-cli # skew protection needs 23.11.0+
A deploy is a versioned, atomic snapshot: Netlify uploads only changed files and switches the live site only after all files land — the site is never in an inconsistent state. A deploy can be a preview or a production version served at your primary domain.
Continuous deployment vs manual deploys: Deploy with Git and the Netlify CLI support continuous deployment — a push auto-triggers a build. Drag and drop and the API create one-off manual deploys. Manual deploys (netlify deploy) do not run a build command; drag-and-drop while logged in is the only exception (framework auto-detected).
⚠ When linking or creating a site, add .netlify to .gitignore. Every linking path writes .netlify/state.json, which must not be committed.
Ways to create a deploy
- Git CD — connect a repo; Netlify builds and deploys on every push (OAuth2 or the Netlify GitHub App). This is the default path.
- CLI —
netlify create,netlify deploy,netlify deploy --prod. - Drag and drop — https://app.netlify.com/drop. Logged in: builds if needed. Not logged in: publishes files as-is.
- API — create deploys via file digest or ZIP (one-off manual).
- Deploy to Netlify button — one-click from a public template repo.
- Build hooks — unique URLs that trigger builds. (Deploys from build hooks are treated as trusted and bypass the deploy request policy.)
- AI agents — Agent Runners (Claude Code, OpenAI Codex, Google Gemini) from the dashboard; every file-changing run auto-generates a Deploy Preview at
agent-<runID>--<site>.netlify.app. The inline preview shown next to the prompt is the same Deploy Preview available at that URL. - Zapier / n8n — automation integrations.
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.

netlify-deploy is a cursor rule published in the GitHub repository netlify/context-and-tools (41 stars, last pushed 2d ago), licensed MIT. It adds 116 tokens to every session and 3,124 once invoked, about $0.0005 per session on Opus 5.5. A static security scan graded it C with 1 finding (hidden instructions). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
