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.

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 | $0.00053 | $0.02382 |
| Opus 5.5 | $0.00021 | $0.00953 |
| Sonnet 5.5 | $0.00011 | $0.00476 |
| Haiku 4.5 | $0.00005 | $0.00238 |
Grade A, and why
firewall-networking 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 17d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.
3. Probe inbound with `curl` from an allowed and a blocked vantage. For an outbound probe from inside the container, use the `cpln` CLI after reading the `cpln` skill. How it starts
The opening of the file, as written. The whole thing — 151 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Firewall & Networking
Deep detail for spec.firewallConfig and the enforcement model behind it; the workload skill owns the summary (deny-by-default, exposure decided at create time, LB picker). Set firewallConfig with create_workload / update_workload — or public: true, the shortcut that opens inbound AND outbound to 0.0.0.0/0 (mutually exclusive with an explicit firewallConfig). A firewall change creates a new deployment version — a rolling replace, live in about a minute (vm workloads are the exception: firewall updates apply in place without restarting the VM).
How rules are enforced
Inbound is checked per request at the mesh sidecar. It counts as fully open only when inboundAllowCIDR contains the literal 0.0.0.0/0 AND inboundBlockedCIDR is empty; anything else is allow-list mode. Blocked beats allowed; a bare IP means /32. Header and geo filters apply to HTTP traffic only — tcp-protocol ports are CIDR-filtered at the connection level instead.
Outbound has two separate paths, which is why CIDR rules beat hostname rules:
- CIDR path — traffic to
outboundAllowCIDRranges bypasses the sidecar and exits directly, on ALL ports unlessoutboundAllowPortis set. - Hostname path — everything else transits the sidecar, which only admits
outboundAllowHostnameentries, matched by Host header (HTTP) or TLS SNI, on ports 80, 443, and 445 (SMB) by default. outboundBlockedCIDRis subtracted at the network layer and beats both paths — an allowed hostname that resolves into a blocked range still fails.- Outbound is fully open only with the literal
0.0.0.0/0inoutboundAllowCIDR.
External inbound
firewallConfig:
external:
inboundAllowCIDR: # max 250 entries; deduped and sorted on save
- 0.0.0.0/0 # or specific: 203.0.113.0/24, 198.51.100.10
inboundBlockedCIDR: # no max; wins over the allow list
- 192.0.2.0/24
External outbound
firewallConfig:
external:
outboundAllowCIDR:
- 198.51.100.0/24 # all ports open to this range while outboundAllowPort is unset
outboundAllowHostname: # lowercase; single wildcard on the prefix only; max 128 chars
- api.stripe.com
- "*.amazonaws.com"
outboundBlockedCIDR:
- 203.0.113.7
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.

firewall-networking is a skill published in the GitHub repository controlplane-com/ai-plugin (11 stars, last pushed 4d ago), licensed MIT. It adds 53 tokens to every session and 2,382 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-08-31.
