Previously a message like `<@&1490963422786093149> help` would spawn a
thread literally named `<@&1490963422786093149> help`, exposing raw
Discord mention markers in the thread list. Only user mentions
(`<@id>`) were being stripped upstream — role mentions (`<@&id>`) and
channel mentions (`<#id>`) leaked through.
Fix: strip all three mention patterns in `_auto_create_thread` before
building the thread name. Collapse runs of whitespace left by the
removal. If the entire content was mention-only, fall back to 'Hermes'
instead of an empty title.
Fixes#6336.
Tests: two new regression guards in test_discord_slash_commands.py
covering mixed-mention content and mention-only content.
Closes#11321, closes#10259.
## Problem
The nested /skill command group (category subcommand groups + skill
subcommands) serialized to ~14KB with the default 75-skill catalog,
exceeding Discord's ~8000-byte per-command registration payload. The
entire tree.sync() rejected with error 50035 — ALL slash commands
including the 27 base commands failed to register.
## Fix
Replace the nested Group layout with a single flat Command:
/skill name:<autocomplete> args:<optional string>
Autocomplete options are fetched dynamically by Discord when the user
types — they do NOT count against the per-command registration budget.
So this single command registers at ~200 bytes regardless of how many
skills exist. Scales to thousands of skills with no size calculations,
no splitting, no hidden skills.
UX improvements:
- Discord live-filters by user's typed prefix against BOTH name and
description, so '/skill pdf' finds 'ocr-and-documents' via its
description. More discoverable than clicking through category menus.
- Unknown skill name → ephemeral error pointing user at autocomplete.
- Stable alphabetical ordering across restarts.
## Why not the other proposed approaches
Three prior PRs tried to fit within the 8KB limit by modifying the
nested layout:
- #10214 (njiangk): truncated all descriptions to 'Run <name>' and
category descriptions to 'Skills'. Works but destroys slash picker UX.
- #11385 (LeonSGP43): 40-char description clamp + iterative
trim-largest-category fallback. Works but HIDES skills the user can
no longer invoke via slash — functional regression.
- #10261 (zeapsu): adaptive split into /skill-<cat> top-level groups.
Preserves all skills but pollutes the slash namespace with 20
top-level commands.
All three work around the symptom. The flat autocomplete design
dissolves the problem — there is no payload-size pressure to manage.
## Tests
tests/gateway/test_discord_slash_commands.py — 5 new test cases replace
the 3 old nested-structure tests:
- flat-not-nested structure assertion
- empty skills → no command registered
- callback dispatches the right cmd_key by name
- unknown name → ephemeral error, no dispatch
- large-catalog regression guard (500 skills) — command payload stays
under 500 bytes regardless
E2E validated against real discord.py 2.7.1:
- Command registers as discord.app_commands.Command (not Group).
- Autocomplete filters by name AND description (verified across several
queries including description-only matches like 'pdf' → OCR skill).
- 500-skill catalog returns max 25 results per autocomplete query
(Discord's hard cap), filtered correctly.
- Choice labels formatted as 'name — description' clamped to 100 chars.
Discord's _register_slash_commands() had a hardcoded list of ~27 commands
while COMMAND_REGISTRY defines 34+ gateway-available commands. Missing
commands (debug, branch, rollback, snapshot, profile, yolo, fast, reload,
commands) were invisible in Discord's / autocomplete — users couldn't
discover them.
Add a dynamic catch-all loop after the explicit registrations that
iterates COMMAND_REGISTRY, skips already-registered commands, and
auto-registers the rest using discord.app_commands.Command(). Commands
with args_hint get an optional string parameter; parameterless commands
get a simple callback.
This ensures any future commands added to COMMAND_REGISTRY automatically
appear on Discord without needing a manual entry in discord.py.
Telegram and Slack already derive dynamically from COMMAND_REGISTRY
via telegram_bot_commands() and slack_subcommand_map() — no changes
needed there.
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
Inspired by Discord community suggestion from bottium.
Set _text_batch_delay_seconds = 0 on test adapter fixtures so messages
dispatch immediately (bypassing async batching). This preserves the
existing synchronous assertion patterns while the batching logic is
tested separately in test_text_batching.py.
Cherry-picked from PR #2017 by @simpolism. Fixes#2011.
Discord slash commands in threads were missing thread_id in the
SessionSource, causing them to route to the parent channel session.
Commands like /usage and /reset returned wrong data or affected the
wrong session.
Detects discord.Thread channels in _build_slash_event and sets
chat_type='thread' with thread_id. Two tests added.
Two changes to align Discord behavior with Slack:
1. Auto-thread on @mention (default: true)
- When someone @mentions the bot in a server channel, a thread is
automatically created from their message and the response goes there.
- Each thread gets its own isolated session (like Slack).
- Configurable via discord.auto_thread in config.yaml (default: true)
or DISCORD_AUTO_THREAD env var (env takes precedence).
- DMs and existing threads are unaffected.
2. Skip @mention in bot-participated threads
- Once the bot has responded in a thread (auto-created or manually
entered), subsequent messages in that thread no longer require
@mention. Users can just type normally.
- Tracked via in-memory set (_bot_participated_threads). After a
gateway restart, users need to @mention once to re-establish.
- Threads the bot hasn't participated in still require @mention.
Config change:
discord:
auto_thread: true # new, added to DEFAULT_CONFIG
Tests: 7 new tests covering auto-thread default, disable, bot thread
participation tracking, and mention skip logic. All 903 gateway tests pass.
- update managed-server compatibility tests to match the current
ServerManager.tool_parser wiring used by hermes_base_env
- make quick-command CLI assertions accept Rich Text objects, which is how
ANSI-safe output is rendered now
- set HERMES_HOME explicitly in the Discord auto-thread config bridge test
so it loads the intended temporary config file
Validated with the targeted test set and the full pytest suite.
- Add /thread slash command that creates a Discord thread and starts a
new Hermes session in it. The starter message (if provided) becomes
the first user input in the new session.
- Add discord.auto_thread config option (DISCORD_AUTO_THREAD env var):
when enabled, every message in a text channel automatically creates
a thread, allowing parallel isolated sessions.
- Fix Discord media method signatures to accept metadata kwarg
(send_voice, send_image_file, send_image) — prevents TypeError
when the base adapter passes platform metadata.
- Fix test mock isolation: add app_commands and ForumChannel to
discord mocks so tests pass in full-suite runs.
