Inspect or repair ESX Legacy adapters and direct ESX integrations using the installed player, callback and inventory contracts.

  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Esx Framework is an agent skill from sky-systems/sky_phone. Inspect or repair ESX Legacy adapters and direct ESX integrations using the installed player, callback and inventory contracts.

Its SKILL.md is about 360 tokens, which your agent loads only when the skill is triggered. The skill folder holds 7 other files (for example `best-practices.md`, `client-functions.md` and `core-concepts.md`).

The repository describes itself as: Phone Script for FiveM. The licence is GPL-3.0.

Example prompts

  • “/esx-framework”

What it can do on your machine

Read from SKILL.md and the folder at commit 81a5177. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Esx Framework loads about 359 tokens when it runs. Until then it costs about 35 tokens; SKILL.md has 136 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~35
When it runs · the whole SKILL.md, loaded when a task matches
~359

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

ESX integration

Identify the installed ESX revision, inventory/provider overrides and owning execution side. Verify only the method/event in question using current official docs and matching source; source map records inspected paths, not universal version promises. For CFX/native use, also verify docs, registration/generated binding and implementation, including context, yield/RPC behavior and source limits.

When the applicable AGENTS.md requires the Sky bridge, keep Sky.FW facades and Sky_Jobs.PlayerCache identity/job/duty; direct ESX belongs in framework adapters. Preserve Sky callbacks/UI/localization and unconditional documented APIs. Otherwise retain resource-owned adapters. External ESX player objects can legitimately be absent; handle that boundary with an explicit result and diagnostic rather than confusing it with a missing framework API.
