Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

SkillSpector: 2 findings, up to medium
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 →

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 | $0.00138 | $0.03306 |
| Opus 5 | $0.00069 | $0.01653 |
| Sonnet 5 | $0.00028 | $0.00661 |
| Haiku 4.5 | $0.00014 | $0.00331 |
Grade A, and why
notte-functions-build 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 11d 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.

Notte Functions Build
Turn a one-off browser task into a deployed, reusable Notte Function. The expensive, non-deterministic part - an agent exploring a site to find where the data actually lives - happens once. The result is a parameterized Function with a stable Function ID that anyone can invoke over HTTP, run from the CLI/SDK, or schedule on a cron. Running 5,000 records later costs nothing extra in exploration.
This is the difference between asking an agent to "scrape Indeed" every time (pay exploration cost and eat non-determinism on every call) and building an indeed-jobs Function once, then calling it with {"keyword": "...", "location": "..."} forever.
Relationship to
notte-browser. This skill builds on the base CLI documented in the notte-browser skill. Load that skill for the full command reference, authentication handling, and security notes. This skill adds the explore-once -> generate -> self-test -> publish pipeline on top of it.
When to use this skill vs. notte-browser
- One-off task ("scrape this page now") -> use
notte-browserdirectly. - Reusable artifact ("I'll run this across many inputs / on a schedule / from my backend") -> use this skill to build a Function.
- A built Function broke (site changed, returns empty) -> use notte-functions-doctor.
The pipeline
Phase 0 Setup ensure the notte CLI is authenticated
Phase 1 Describe parse intent, check the marketplace, confirm a plan [GATE]
Phase 2 Explore drive the site ONCE; find the stable path (API-first)
Phase 3 Generate export workflow-code; parameterize; stamp a health contract
Phase 4 Publish+Test create the Function; self-test until green; self-repair
Delivery report Function ID + HTTP snippet + coverage; schedule [GATE]
Phases 2 and 3 may loop per capability when a task spans several stages (search page + detail page, for example). Finish one stable capability before starting the next.
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.

notte-functions-build is a skill published in the GitHub repository nottelabs/notte-skills (11 stars, last pushed 6d ago), licensed MIT. It adds 138 tokens to every session and 3,306 once invoked, about $0.0007 per session on Opus 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.
