What is kesekit-check?

A pre-deployment security checklist based on guidance from South Korea’s KISA, covering infrastructure, AI, robots, space systems, secure coding, zero-trust security, and software supply chains.

Use it to run security and compliance reviews for servers, AI systems, robots, satellites, JavaScript or Python applications, zero-trust setups, and software supply chains using an SBOM, a list of included software components.

It helps you review security requirements before releasing a system, without choosing a checklist manually. It also organizes checks for areas such as software components and system access.

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	$0.00120	$0.01322
Opus 5.5	$0.00048	$0.00529
Sonnet 5.5	$0.00024	$0.00264
Haiku 4.5	$0.00012	$0.00132

Security

Grade A, and why

kesekit-check 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 2mo 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.

KESE Pre-Deployment Security Compliance Checklist

Run pre-deployment security checks. Auto-selects guideline based on user context.

Guideline Selection

#	Guideline	Description
1	CII Compliance	70-item pre-deployment checklist
2	AI Security Checklist	AI developer/provider verification
3	Robot Security Checklist	Robot system 11 categories, 103 items
4	Space Security Checklist	Satellite/GSaaS/supply chain 12 domains, 53 items
5	Secure Coding Checklist	JavaScript/Python code review (7 categories, 46 CWE)
6	Zero Trust Checklist	Zero Trust maturity assessment (8 elements, 4 maturity levels, ~396 items)
7	SW Supply Chain Checklist	SBOM-based supply chain security (5 phases, 29 items)

CII Branch

Load reference files from templates/cii/ based on detected environment. Check commands available in scripts/cii/ directory. Check categories: Account Security (15), Access Control (15), Encryption (12), Logging (10), Service Hardening (12), Patch Management (6).

Severity: Critical (deployment blocker) → High → Medium → Low

AI Security Branch

Load from references/ai-security/ for overview and guidance, and templates/ai-security/ for assessment checklists. Check developer (54 items), service provider, or user checklists by lifecycle phase.

Robot Security Branch

Load from templates/robot-security/. Start with overview.md, then select one or more category references (ssdf.md, supply-chain.md, iec62443.md, cyber-resilience.md, wireless.md) based on the robot type, interfaces, and regulatory context.

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.
