name	deprecated
description	Retire, preserve, explain, or replace old skills without silently deleting useful history. Use when the user asks to deprecate a skill, replace a skill, audit stale skills, or understand why a skill should no longer be used.

Deprecated Skill Maintenance

Use this skill when a skill is no longer recommended but should remain understandable.

Purpose

skills/deprecated/ keeps retired skills visible until users and workflows have moved away from them. Deprecation should explain what replaced the skill and why.

When To Deprecate

• Another skill fully replaces it.
• The workflow is unsafe or misleading.
• The scope became too broad or unclear.
• The domain changed and the instructions are stale.
• It was an experiment that should not be promoted.

Rules

• Do not delete a retired skill until replacements and references are clear.
• Do not leave active workflows pointing at deprecated skills.
• Keep the deprecation reason short and factual.
• Preserve useful reference material when it can be safely reused.

Workflow

1. Identify replacement

   • Name the new skill or workflow if one exists.
   • If no replacement exists, state that clearly.

2. Move carefully

   • Move the old skill folder into skills/deprecated/.
   • Keep its SKILL.md readable.
   • Add a deprecation note near the top.

3. Update references

   • Remove it from README stable skill lists.
   • Remove it from workflow recommendations.
   • Update data/workflows.json or data/tools.json if needed.

4. Explain the reason

   • State why the skill was retired.
   • State what to use instead.
   • Preserve any useful reference links.

5. Validate

   • Run skill and workflow validation.
   • Confirm no active workflow depends on the deprecated skill.
