Skills appear duplicated/triplicated in the slash command list

Description

When invoking a skill via /, the same skill appears multiple times in the autocomplete/selection list. In my case, /proofread and /prakriya-check each appear 3 times (and 2 times respectively based on the system-reminder context).

Steps to reproduce

1. Install one or more skills under ~/.claude/skills/
2. Type / in the Claude Code prompt
3. Observe the skill listed multiple times in the dropdown

Expected behavior

Each skill should appear exactly once.

Environment

• Claude Code version: 2.1.114
• OS: Linux (WSL2)
• Skills directory: ~/.claude/skills/

Notes

There is only one SKILL.md file per skill on disk — the duplication appears to be in how the harness enumerates or injects skills into the system prompt, not in the files themselves.
