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 | $0.00094 | $0.03416 |
| Opus 5 | $0.00047 | $0.01708 |
| Sonnet 5 | $0.00019 | $0.00683 |
| Haiku 4.5 | $0.00009 | $0.00342 |
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 3d 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 — 246 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Netlify deploy
Deploy context config (netlify.toml, current form)
Configure per-context build settings in netlify.toml at the repo root. Five predefined contexts: production, deploy-preview, branch-deploy, preview-server, dev. Branch names also work as custom contexts (a staging branch matches a staging context).
[context.production]
command = "make production"
[context.production.environment]
ACCESS_TOKEN = "super secret"
# Plugins context REQUIRES double brackets:
[[context.production.plugins]]
package = "@netlify/plugin-sitemap"
[context.deploy-preview.environment]
ACCESS_TOKEN = "not so secret"
[context.branch-deploy]
command = "make staging"
[context.dev.environment]
NODE_ENV = "development"
# Specific-branch context (overrides branch-deploy):
[context.feature]
command = "make feature"
[context."features/branch"]
command = "gulp"
Precedence: site globals < context overrides; production overrides globals when building production; more specific contexts (a named branch) override general ones (branch-deploy). Only explicitly-set options are overridden. File-based config overrides UI settings.
Footgun — secrets in netlify.toml: netlify.toml is committed to your repo. Do not put sensitive env values here, especially for public repos. Set secrets via the Netlify UI/CLI/API instead. Also: env vars declared in netlify.toml are NOT available to the deploy environment (Functions/Runtime/Post-processing scopes) — only UI/CLI/API-created vars are.
CLI deploys
netlify create # new project from a natural-language prompt
netlify deploy # manual deploy, no continuous deployment
netlify deploy --prod # deploy directly to production
netlify deploy --allow-anonymous # temp deploy, claim within 1 hour
npm update -g netlify-cli # skew protection needs CLI v23.11.0+
Manual deploys do NOT run a build command (exception: Netlify Drop builds for you when logged in). Anonymous deploys create a temporary project claimable within one hour; on claim it adopts the team's default visibility.
What ships with it
5 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-deploy is a skill published in the GitHub repository PracticalSwan/agent-skills (14 stars, last pushed 3d ago), licensed MIT. It adds 94 tokens to every session and 3,416 once invoked, about $0.0005 per session on Opus 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 2026-09-03.
