Docs name ALTIMATE_CLI_DISABLE_EXTERNAL_SKILLS but only OPENCODE_DISABLE_EXTERNAL_SKILLS is read #1329

Summary

docs/docs/configure/skills.md ("Disabling External Skills") tells users to set:

export ALTIMATE_CLI_DISABLE_EXTERNAL_SKILLS=true

The flag code only reads the OPENCODE_ spelling:

// packages/opencode/src/flag/flag.ts
export const OPENCODE_DISABLE_EXTERNAL_SKILLS =
  OPENCODE_DISABLE_CLAUDE_CODE_SKILLS || truthy("OPENCODE_DISABLE_EXTERNAL_SKILLS")

Other flags in the same file use altTruthy("ALTIMATE_CLI_…", "OPENCODE_…") for dual support (for example OPENCODE_DISABLE_AUTOUPDATE), so this one was missed. Setting the documented variable has no effect: skills from ~/.claude/skills and ~/.agents/skills still load.

Verified on v0.12.0: with only ALTIMATE_CLI_DISABLE_EXTERNAL_SKILLS=true set, a personal skill from ~/.claude/skills was listed and invoked by the model; with OPENCODE_DISABLE_EXTERNAL_SKILLS=true it was not.

Fix

Use altTruthy("ALTIMATE_CLI_DISABLE_EXTERNAL_SKILLS", "OPENCODE_DISABLE_EXTERNAL_SKILLS") in flag.ts (and the same for OPENCODE_DISABLE_CLAUDE_CODE_SKILLS / OPENCODE_DISABLE_CLAUDE_CODE if they are documented under the ALTIMATE_CLI_ name), or change the docs to the OPENCODE_ name. docs/docs/usage/cli.md should list whichever name wins in its environment-variable table.
