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 | $0.00055 | $0.01321 |
| Opus 5 | $0.00028 | $0.00660 |
| Sonnet 5 | $0.00011 | $0.00264 |
| Haiku 4.5 | $0.00006 | $0.00132 |
Grade A, and why
navvi-signup scanned grade A with 0 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 12d 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.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 130 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Navvi Signup
Account creation skill. Creates a new account on a service using Navvi MCP tools and gopass credentials.
First Steps (ALWAYS)
- Read the persona brief — this tells you who you are, your email, your accounts, your history:
mcp__navvi__navvi_milestone(action="brief", persona="{persona}")
Use the primary email from the brief when signing up. Never guess from the persona name.
- Unlock atomic tools — you'll need them for form filling:
mcp__navvi__navvi_atomic(enable=true)
Prerequisites
- Navvi container must be running (
mcp__navvi__navvi_start) - GPG/gopass must be initialized (needs
NAVVI_GPG_PASSPHRASEin MCP config)
Workflow
Step 1: Check for existing account
Read persona://{persona}/state
If an account already exists for this service, report it and stop.
Step 2: Generate credentials
mcp__navvi__navvi_creds(action="generate", entry="navvi/{persona}/{service}", username="{chosen_username}")
Password is created inside the container and NEVER appears in your context.
Step 3: Navigate to signup page
mcp__navvi__navvi_open(url="https://{service}/signup")
Take a screenshot to see the page. If no obvious signup URL, try the homepage and look for a "Sign Up" or "Create Account" link.
Step 4: Fill the signup form
mcp__navvi__navvi_creds(action="autofill", entry="navvi/{persona}/{service}")
If autofill fails (non-standard form, multiple forms with same field names):
- Use
navvi_findto locate the correct form fields - Use
navvi_fillfor username/email only - For password: use
navvi_creds(action="autofill")with explicit selectors, or tab to the password field and use autofill - NEVER type passwords manually
Custom Dropdowns (Fluent UI, React Select, etc.)
Do NOT use navvi_browse for custom dropdowns — it gets stuck in scroll loops.
Use atomic tools directly:
- Find the dropdown trigger:
navvi_find("[role=combobox]")ornavvi_find("select") - Click to open it:
navvi_click(x, y) - Find all options:
navvi_find("[role=option]", all=true) - Find and click the desired option by text match
- If the option list is long, use
navvi_find("[role=option]:text('Chile')")or scroll within the dropdown
What ships with it
1 file 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.

navvi-signup is a skill published in the GitHub repository fellowship-dev/navvi (9 stars, last pushed 1mo ago), licensed MIT. It adds 55 tokens to every session and 1,321 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
