A security-fixing skill for computer systems, AI, robots, space systems, software code, Zero Trust setups, and software supply chains.

Use it to fix vulnerable JavaScript or Python patterns, harden systems, address Zero Trust gaps, or scan and remediate software supply-chain risks using an SBOM, a list of software components and versions.

It turns security assessment results into hardening scripts or code fixes, reducing the need to plan each remediation manually.

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	$0.00106	$0.01147
Opus 5.5	$0.00042	$0.00459
Sonnet 5.5	$0.00021	$0.00229
Haiku 4.5	$0.00011	$0.00115

Security

Grade A, and why

kesekit-fix 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 Vulnerability Auto-Fix

Generate and apply fixes based on vulnerability assessment results. Auto-selects guideline.

Guideline Selection

#	Guideline	Description
1	CII Hardening	Platform-specific hardening scripts
2	AI Security Fixes	AI system security hardening
3	Robot Security Fixes	Robot system hardening (IEC 62443, CRA, RED)
4	Space Security Fixes	Space system hardening (CMMC, K-RMF, NIS2, NIST IR 8401)
5	Secure Coding Fixes	Auto-fix vulnerable code patterns (JS/Python, 46 CWE)
6	Zero Trust Fixes	Zero Trust gap remediation (8 elements, 4 maturity levels, ~396 items)
7	SW Supply Chain Fixes	SBOM generation, vulnerability scanning, remediation (29 items)

Zero Trust, ZTA, ZTNA, 제로트러스트, 마이크로세그멘테이션, microsegmentation, SDP, SASE, PEP/PDP, never trust always verify → Zero Trust SBOM, supply chain, 공급망, C-SCRM, SCA, CycloneDX, SPDX, npm audit, pip-audit → SW Supply Chain

CII Branch

Load reference from templates/cii/ → generate hardening scripts saved to scripts/kese-hardening/. Check commands available in scripts/cii/ directory.

AI Security Branch

Load from references/ai-security/ for overview and guidance, and templates/ai-security/ for assessment checklists → generate security hardening code for AI pipelines, model security, API protection, LLM guardrails.

Robot Security Branch

Load from templates/robot-security/ → generate robot security remediation guidance for secure development, supply chain controls, IEC 62443 controls, cyber resilience planning, and wireless security.

Space Security Branch

Load from references/space-security/ for overview and supply chain guidance, and templates/space-security/ for assessment checklists → generate space system hardening guidance. Fix scripts in scripts/space-security/access-control-fix.md, scripts/space-security/system-security-fix.md, scripts/space-security/operations-fix.md.

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.
