Instead of consuming one top-level slash command slot per skill (hitting the
100-command limit with ~26 built-ins + 74 skills), skills are now organized
under a single /skill group command with category-based subcommand groups:
/skill creative ascii-art [args]
/skill media gif-search [args]
/skill mlops axolotl [args]
Discord supports 25 subcommand groups × 25 subcommands = 625 max skills,
well beyond the previous 74-slot ceiling.
Categories are derived from the skill directory structure:
- skills/creative/ascii-art/ → category 'creative'
- skills/mlops/training/axolotl/ → category 'mlops' (top-level parent)
- skills/dogfood/ → uncategorized (direct subcommand)
Changes:
- hermes_cli/commands.py: add discord_skill_commands_by_category() with
category grouping, hub/disabled filtering, Discord limit enforcement
- gateway/platforms/discord.py: replace top-level skill registration with
_register_skill_group() using app_commands.Group hierarchy
- tests: 7 new tests covering group creation, category grouping,
uncategorized skills, hub exclusion, deep nesting, empty skills,
and handler dispatch
