hermes - 💡(How to fix) Fix feat: fuzzy substring matching for /skill autocomplete [1 pull requests]

Problem

The /skill slash command autocomplete only matches by prefix (startswith). This means typing /skill pdf will NOT match nano-pdf, /skill xlsx will NOT match docx, etc.

# hermes_cli/commands.py, get_completions() ~line 1655
if cmd_name.startswith(word):  # ← pure prefix match

This is frustrating when you remember what a skill does but not its exact name prefix. The @ file completion already has fuzzy matching (_fuzzy_file_completions), so the pattern exists in the codebase.

Proposed Fix

Add substring matching as a fallback when no prefix matches are found:

# First pass: prefix matches (existing behavior, keep priority)
prefix_matches = []
substring_matches = []

for cmd, info in self._iter_skill_commands().items():
    cmd_name = cmd[1:]
    if cmd_name.startswith(word):
        prefix_matches.append((cmd, info))
    elif word in cmd_name:  # substring fallback
        substring_matches.append((cmd, info))

for cmd, info in prefix_matches + substring_matches:
    # yield completions...

Same pattern should apply to skill bundles and plugin commands.

Example

Environment

• Hermes Agent: latest (main branch)
• CLI autocomplete via prompt_toolkit
