# Firewall policy review
Do not use for IPS signature tuning or endpoint EDR. Not for SASE SWG categories.
## Procedure
1. Export the rulebase. Hit-count sort. Unused 90-day rules are candidates, not automatic deletes.
2. Flag any-any, any-app, and service-any above a named rule. Shadow detection before inserts.
3. Require log-end and a named owner tag on every allow.
4. App-ID / application overrides: document the exception and an expiry.
5. Verify with a packet that should hit the new rule and a packet that must still hit the old one.
```text
rule 142 src any dst any app any action allow SHADOWED by 87
rule 210 src 10.8.0.0/16 dst payments app ssl action allow no-log
```
## Anti-patterns
- Never insert at the top "just to test".
- Do not disable a rule without a hit-count export attached to the ticket.
## Safety
Reviews are read-only. Commits are change-guarded and twin-tested on a lab vsys where possible.

Ultra-compressed communication mode. Cuts token usage ~75% by speaking like caveman while keeping full technical accuracy. Supports intensity levels: lite, full (default), ultra, wenyan-lite, wenyan-full, wenyan-ultra. Use when user says "caveman mode", "talk like caveman", "use caveman", "less tokens", "be brief", or invokes /caveman. Also auto-triggers when token efficiency is requested.
Adversarial multi-agent planning skill. Self-orchestrates 5 hostile category members (unspecified-low, unspecified-high, deep, ultrabrain, artistry) via team-mode for ruthless cross-critique debate, distills only the defensible insights, then MANDATORILY hands the distilled insight bundle to the `plan` agent for executable plan formalization. Use when planning needs maximum rigor and surfacing of weak assumptions, blind spots, and over-engineering. Triggers: 'hyperplan', 'hpp', '/hyperplan', ...
Routes multi-tool workflows through MCP servers for large datasets and pipelines. Use when Bash tool overhead is limiting throughput on data-heavy tasks.

Recovers prior coding-agent session context by running `catchup <agent> --since-compact`, which extracts a clean summary of a previous Codex, Claude Code, Antigravity, OpenCode, or Pi Agent session. Use when the user says "catch up", "what did the last session do", "get me up to speed", "I switched agents", or asks to recover/summarize a previous session before continuing. Do NOT use for the current conversation, git history, or any non-agent log.
