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 | $0.00077 | $0.02039 |
| Opus 5 | $0.00039 | $0.01019 |
| Sonnet 5 | $0.00015 | $0.00408 |
| Haiku 4.5 | $0.00008 | $0.00204 |
Grade A, and why
firewall-config-conversion 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 9d 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.

Firewall Config Conversion
Overview
Use this skill to convert a firewall or NGFW configuration from one vendor to another by pivoting through the parsing-* intermediate JSON schema. Any source vendor that has a parser (Cisco ASA/FTD, FortiGate, Palo Alto PAN-OS, Juniper SRX) can be converted to any of the four supported targets, because every conversion reads the same normalized schema — address_objects, address_groups, service_objects, service_groups, security_policies, nat_rules, zones, interfaces, static_routes / virtual_routers / routing, vpn_tunnels, ha_config, and system (abbreviated — see the canonical intermediate-schema.md in the parsing-srx-configs skill for the full top-level structure) — and re-emits it in the target's native CLI. This schema-pivot design means there is one emitter per target rather than one translator per source/target pair.
The output is always two parts: the target vendor's native configuration, followed by a per-section fidelity report. The config carries inline # CAVEAT: comments wherever a translation is lossy or approximate, and the fidelity report classifies each schema section as converted, converted-with-caveats, or manual-not-converted, then lists the manual follow-up items that a human must complete on the target device.
This skill produces a migration draft, never a production-ready config. Vendor security models differ enough — zones versus security-levels, App-ID versus port-based services, routing-instances versus contexts or vsys — that no automated conversion is safe to commit unreviewed. Secrets are never emitted: VPN pre-shared keys, certificates, and admin passwords are always replaced with placeholders and flagged as manual items, so the draft can be shared and reviewed without leaking credentials.
Scope and routing
Convert only normalized parser output and only to vendors with an emitter in references/; never improvise unsupported target syntax. Route audits to firewall-best-practices-audit and comparisons to firewall-config-diff.
What ships with it
8 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.

firewall-config-conversion is a skill published in the GitHub repository fastrevmd-lab/fwskillsshare (8 stars, last pushed 12d ago), licensed MIT. It adds 77 tokens to every session and 2,039 once invoked, about $0.0004 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.
