A configuration guide for Cloudflare Tunnel and Access. A tunnel gives a private service a reachable URL, while Access controls who can use it.

Use it to create the tunnel, grant or revoke a person's access, and configure wildcard subdomains for public apps.

It organizes the setup and permission changes needed to expose woltspace or apps while restricting access to approved people.

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.

Any agent

Token cost

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	$0.00029	$0.00759
Opus 5.5	$0.00012	$0.00304
Sonnet 5.5	$0.00006	$0.00152
Haiku 4.5	$0.00003	$0.00076

Security

Grade A, and why

cloudflare 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 2mo 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 — 58 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Woltspace Cloudflare

Single skill for everything Cloudflare-related on woltspace: the named tunnel that gives the lodge a permanent URL, the Access policies that gate who can reach it, and the wildcard setup that lets public apps live at {app}.{domain}.

This skill routes to a sub-doc based on what the user wants. Ask first — don't run any sub-doc by default.

What do you want to do?

Ask the user which task they need, then read the matching sub-doc and follow it step by step.

User intent	Sub-doc	When to use
First-time tunnel + Access setup	`setup.md`	No named tunnel yet, or `CLOUDFLARE_TUNNEL_TOKEN` is unset in `/workspace/wolts/.env`.
Add a person to an existing app	`add-access.md`	Tunnel + Access already configured. Granting an email access to the lodge, the wildcard, or one specific subdomain.
Remove a person from an app	`remove-access.md`	Revoking a previously-granted email.

Quick check for which state the user is in:

source /workspace/wolts/.env
echo "TUNNEL_TOKEN=${CLOUDFLARE_TUNNEL_TOKEN:+SET}"
echo "TUNNEL_URL=${CLOUDFLARE_TUNNEL_URL:-NOT SET}"
echo "API_TOKEN=${CLOUDFLARE_API_TOKEN:+SET}"
echo "ACCOUNT_ID=${CLOUDFLARE_ACCOUNT_ID:-NOT SET}"

All four set → tunnel is up; user is probably here for add-access.md or remove-access.md.
TUNNEL_TOKEN unset but API_TOKEN set → setup was started but tunnel never landed; resume setup.md from Step 4.
All unset → fresh install; start at setup.md Step 1.

Notes that apply to every sub-doc

All sub-docs are idempotent — safe to re-run. If something is already in place, validate and skip.
The shared .env lives at /workspace/wolts/.env. Every Cloudflare API call reads from there.
Required token permissions for the API token: Cloudflare Tunnel: Edit, DNS: Edit (scoped to the user's zone), Access: Apps and Policies: Edit.
Cloudflare Access free tier is 50 users per application. Each lodge or wildcard is one application; the limit doesn't stack across them.
The Access auth cookie is scoped to .{domain}, so a user who logs into one subdomain stays logged in across every app they have access to for the session duration.
Valid session_duration values: 30m, 6h, 12h, 24h, 168h, 730h (1 month is the max on the free plan).

Changes

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.
