Use this skill every time you produce a candidate Snort rule. Validation runs snort -T inside the IDS container via SSH, so it catches real syntax errors before deployment reloads the engine.
snort-rule-generation.assign_sid and deploy_rule.validate_rule_syntax(rule: str) -> str
Returns one of:
"VALID" — syntax accepted. You may proceed to assign_sid."INVALID: <error>" — syntax rejected. You MUST regenerate before deployment.sid:0; placeholder).VALID, proceed.INVALID, read the error message carefully. The most common causes are:
rawbytes, threshold, uricontent, resp, react, tag)nocase, offset, depth) that should be comma-separated inside the content optionflow:stateless combined with another flow optionrev, and call validate_rule_syntax again on the corrected rule.IterationResult.rules_attempted.You have at most max_internal_attempts regenerations per variant cycle. Spend them on real refinement, not on retries of identical syntax. If you exhaust the budget with only syntax errors, return IterationResult(fired=False, diagnosis="syntax-budget-exhausted: <last error>").
Generate Snort 3.9.7.0 IDS rules from a natural-language operator intent. Use whenever you need to write a new rule, refine an existing one, or recover from a syntax error.
Reuse Snort rules that already fired in past experiments. ALWAYS consult this skill at the start of every cycle BEFORE writing a new rule. Validated rules are known-good detection patterns persisted per attack_id under data/validated_rules/.

How to map an operator intent to one of the attacks discovered on the attacker host. Use this before calling execute_attack.
