FiveM Deployment

Choosing an FXServer artifact, keeping it inside its support window, and writing a server.cfg that starts.

Activation Contract

Load this skill when the user asks which artifact to run, how to update FXServer or txAdmin, why clients cannot connect after an update, what sv_enforceGameBuild should be, or how to write or audit server.cfg.

Hard Rules

Never state a build number from memory. Read recommended and latest from the changelogs API before answering.
Ignore the critical and optional fields. They are stale-pinned to build 7290 and are not maintained.
EOL is rolling and per build. A build that works today can expire next week; check support_policy_eol for the exact build in use.
sv_replaceExeToSwitchBuilds is deprecated as of build 35245. Never emit it.
On Enhanced, sv_enforceGameBuild accepts only 1 (base game, no DLC); numeric build values are Legacy-only.
sv_enforceGameBuild can only be set at startup, never at runtime.
Never recommend sv_scriptHookAllowed true. It makes the server vulnerable.
Resource load order in server.cfg is literal: dependencies must be ensured before dependents.

Decision Gates

Situation	Build to pick
Production server	`recommended` from the API
Testing a new game DLC	`latest`
Currently below 35245	Upgrade to 35245 or later before October 15 2026
Build's `support_policy_eol` date has passed	Upgrade now; it is out of support

Symptom	Read
Clients cannot join after an update	rules/compatibility-window.md
Choosing or verifying a build	rules/artifacts.md
Server will not start / bad convar	rules/server-cfg.md
Updating artifacts in place	rules/txadmin.md

Execution Steps

Fetch the lifecycle JSON for the platform (linux or win32) and read recommended, latest, support_policy, support_policy_eol.
Compare the user's current build against recommended and against its own support_policy_eol entry.
If the current build is older than 35245, flag the October 15 2026 compatibility cutoff.
Set sv_enforceGameBuild per the Legacy/Enhanced rule above, or omit it to take the default.
Audit server.cfg against rules/server-cfg.md before deploying.
Restate the build number, its EOL value, and the source URL in the answer.

Output Contract

Return the chosen build number, its EOL timestamp, and the API URL you read it from. Emit server.cfg lines as runnable cfg blocks with ensure order intact. Never invent a build number, convar, or txAdmin menu path.
