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 | $0.00128 | $0.03690 |
| Opus 5 | $0.00064 | $0.01845 |
| Sonnet 5 | $0.00026 | $0.00738 |
| Haiku 4.5 | $0.00013 | $0.00369 |
Grade C, and why
netlify-identity scanned grade C with 2 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.
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.

How it starts
The opening of the file, as written. The whole thing — 294 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Netlify Identity
Auth and user management for a Netlify site without requiring visitors to be Netlify users. Package: @netlify/identity.
Reach for @netlify/identity. Do NOT use the legacy netlify-identity-widget or gotrue-js for new work — same capabilities, simpler API, built-in server-side support.
Footguns — read first
- Identity does not work under
netlify dev. Test auth flows on a deploy — Deploy Previews work. Localnetlify devcannot exercise/.netlify/identity/*. - Never build a from-scratch third-party OAuth flow beside Identity — no provider app registration in code, no
client_id/secretin code, no custom callback token exchange. UseoauthLogin()+handleAuthCallback(). Raw OAuth beside Identity is the single most common source of rework. - Identity config has no public API — dashboard only. Never curl
api.netlify.comto flip/inspect Identity settings, never read tokens from~/Library/Preferences/netlify/config.json, never probe undocumented endpoints. - RBAC redirects without a fallback = raw 404. A visitor lacking the role gets a bare 404 with no way to log in. Always add a fallback rule.
- Server-side
login()/signup()/logout()need CSRF protection. CallverifyRequestOrigin(req)first, or an attacker can log a victim into the attacker's account. - Site-gating ("lock this site to my company", employees-only) → route to netlify-access-control first. Identity is the app-level user layer only.
- On failure (callback 404s,
/.netlify/identity/*unreachable, OAuth doesn't return): surface the error, the dashboard URL, and the setting to check — then stop. Do not invent recovery commands.
Setup
Identity must be enabled in the dashboard first (no API): Project configuration > Identity (https://app.netlify.com/projects/{site_name}/configuration/identity) → Enable Identity.
npm install @netlify/identity
HTTPS is required. On a custom domain, get HTTPS/SSL working before integrating Identity.
What ships with it
2 files 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.

netlify-identity is a skill published in the GitHub repository netlify/context-and-tools (36 stars, last pushed yesterday), licensed MIT. It adds 128 tokens to every session and 3,690 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it C with 2 findings (hidden instructions, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
