Fivem

FiveM RP server engineering for QBCore, ESX, and QBox. Use for framework-level scripting, fxmanifest.lua/config.lua validation, resource debugging, dependency orchestration, MLO/streaming fixes, performance optimization (client/server), artifact/gamebuild compatibility, inventory/job/gang systems, and SSH key generation for SFTP.

Security Scan

The skill is an instruction-only FiveM/RP engineering helper whose declared requirements and instructions are consistent with its stated purpose and do not request extra credentials or install code.

Purpose & Capability

Name/description (FiveM RP engineering, QBCore/ESX/QBox, config/manifest validation, performance, MLOs, SSH key generation) matches the SKILL.md content which is a comprehensive engineering checklist and guidance for those tasks. The skill declares no env vars, binaries, or installs, which is proportionate for a documentation/instruction skill.

Instruction Scope

SKILL.md contains detailed, domain-specific guidance (lua, manifests, mapping, profiling, etc.) and references internal checklists. It does not instruct the agent to read arbitrary system files, exfiltrate data, or call unexpected external endpoints. The mention of SSH key generation is appropriate for SFTP guidance and does not itself request private keys or credentials.

Install Mechanism

No install spec and no code files (instruction-only). Nothing is downloaded or written to disk by the skill itself — lowest-risk install posture.

Credentials

No required environment variables, credentials, or config paths are declared. The scope (server engineering guidance) doesn't require platform credentials in this instruction-only form.

Persistence & Privilege

always:false and default invocation settings. The skill does not request persistent system presence or modification of other skills or agent-wide configuration.

Assessment

This is an instruction-only FiveM engineering guide — it doesn't install software or ask for credentials, so the direct risk is low. Before running any commands the skill suggests, review them yourself and avoid pasting private keys or tokens into chat. If the agent recommends generating SSH keys for SFTP, generate them locally and keep private keys private; do not upload them to third-party services. Note that the SKILL.md references several 'references/...' files that are not bundled, so expect the skill to provide guidance rather than runnable artifacts. If you plan to let the agent act autonomously on your systems later, grant only the minimal credentials and access needed at that time and monitor actions.
