What is performing-cloud-native-forensics-with-falco?

A guide to using Falco to detect and investigate suspicious activity inside containers and Kubernetes, a system for running and managing containers. It uses rules that observe operating-system events such as shell launches, file changes, network activity, and privilege escalation.

Use it to write and manage detection rules, investigate container incidents, monitor Kubernetes workloads, and verify that security events are being collected.

It helps identify attacks while workloads are running and exposes common blind spots, such as missing event collection, ignored processes, or dropped alerts under load. It is for runtime activity, not a complete security solution.

SkillSpector: 2 findings, up to high

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

high Privilege Escalation · line 75
Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.

Fix: Remove references to credential paths. Use environment variables or secrets managers. For docs, use placeholder paths (e.g., /path/to/config). Never load .env or token files in production code paths.

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	$0.00077	$0.00979
Opus 5	$0.00039	$0.00490

Security

Grade B, and why

performing-cloud-native-forensics-with-falco scanned grade B 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 7d 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.

Reaches for credential filesmediumPrivilege escalation

SSH keys, cloud credentials, git-credentials, .npmrc, /etc/shadow: reading these is how a config file becomes a credential leak.

2. Sensitive file access (/etc/shadow, /etc/passwd)

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.
