Use when

• The task matches this domain: "Build-time image compression for static websites. Compresses photos from photo-bank/ to under 500KB while retaining quality before copying to src/assets/images/. Uses Sharp (Node.js) as primary tool. Runs as part of photo-manager pipeline."
• The user needs an implementation-facing skill rather than a general discussion.

Do not use when

• The prerequisite upstream context is missing and the task is not yet execution-ready.
• Another narrower skill is the clear better fit for the exact subtask.

Required inputs

• Project context, current files, and any constraints that affect implementation.
• Upstream artifacts produced by earlier skills when this skill is part of a pipeline.

Workflow

1. Read only the relevant project inputs and preserved guidance before acting.
2. Choose the smallest set of references needed for the current job.
3. Produce the implementation, configuration, or guidance this skill owns.
4. Validate that the result stays compatible with the rest of the repository workflow.

Quality standards

• Outputs must be implementation-ready and internally consistent.
• Preserve existing behavior unless the task explicitly requires a change.
• Avoid host-specific path assumptions so the skill remains portable.

Anti-patterns

• Do not hardcode .Codex/skills or another single install path.
• Do not skip validation against upstream or downstream dependencies.
• Do not generate generic output that ignores the actual project context.

Outputs

• Implementation guidance, configuration, generated artifacts, or concrete follow-on steps.

References

• Start with references/legacy-guidance.md when you need the preserved detailed instructions from the previous skill version.
• Read only the specific files under references/ that match the current task instead of loading the whole directory.
• This skill has no bundled scripts by default; keep execution focused on the documented workflow and any existing project files.

Notes

• Treat this SKILL.md as the portable execution layer for both Codex and Codex.
• Preserve existing project behavior unless the current task explicitly requires a change.
