* feat(gateway): skill-aware slash commands, paginated /commands, Telegram 100-cap Map active skills to Telegram's slash command menu so users can discover and invoke skills directly. Three changes: 1. Telegram menu now includes active skill commands alongside built-in commands, capped at 100 entries (Telegram Bot API limit). Overflow commands remain callable but hidden from the picker. Logged at startup when cap is hit. 2. New /commands [page] gateway command for paginated browsing of all commands + skills. /help now shows first 10 skill commands and points to /commands for the full list. 3. When a user types a slash command that matches a disabled or uninstalled skill, they get actionable guidance: - Disabled: 'Enable it with: hermes skills config' - Optional (not installed): 'Install with: hermes skills install official/<path>' Built on ideas from PR #3921 by @kshitijk4poor. * chore: move 21 niche skills to optional-skills Move specialized/niche skills from built-in (skills/) to optional (optional-skills/) to reduce the default skill count. Users can install them with: hermes skills install official/<category>/<name> Moved skills (21): - mlops: accelerate, chroma, faiss, flash-attention, hermes-atropos-environments, huggingface-tokenizers, instructor, lambda-labs, llava, nemo-curator, pinecone, pytorch-lightning, qdrant, saelens, simpo, slime, tensorrt-llm, torchtitan - research: domain-intel, duckduckgo-search - devops: inference-sh cli Built-in skills: 96 → 75 Optional skills: 22 → 43 * fix: only include repo built-in skills in Telegram menu, not user-installed User-installed skills (from hub or manually added) stay accessible via /skills and by typing the command directly, but don't get registered in the Telegram slash command picker. Only skills whose SKILL.md is under the repo's skills/ directory are included in the menu. This keeps the Telegram menu focused on the curated built-in set while user-installed skills remain discoverable through /skills and /commands.

Abstract Methods (MUST implement)
| Method | Signature | Description |
|---|---|---|
get_next_item() |
async def get_next_item(self) -> Item |
Return next item for trajectory. Return None to pause. |
evaluate() |
async def evaluate(self, *args, **kwargs) |
Called every steps_per_eval steps. |
setup() |
async def setup(self) |
Called once at start. Load datasets, init models. |
collect_trajectory() |
async def collect_trajectory(self, item) -> Tuple[Optional[ScoredDataItem], List[Item]] |
Single rollout. Or override collect_trajectories instead. |
Overridable Methods
| Method | Default Behavior | Override When |
|---|---|---|
collect_trajectories() |
Runs collect_trajectory group_size times in parallel | Batch generation, MCTS, coupled rollouts |
wandb_log() |
Logs completion lengths, rollout table, perf stats | Add custom metrics (always call super) |
config_init() |
Returns (env_config_cls(), ServerBaseline()) | Custom defaults + server configs |
postprocess_histories() |
Passthrough | Final processing before sending to trainer |
save_checkpoint() |
Saves JSON to checkpoint_dir | Custom serialization |
cleanup() |
No-op | Release resources after each rollout |
ScoredDataGroup Structure
ScoredDataGroup = TypedDict with:
tokens: List[List[int]] # Token IDs per rollout
masks: List[List[int]] # -100=prompt, token_id=completion
scores: List[float] # Score per rollout
advantages: Optional[...] # Per-token advantages
ref_logprobs: Optional[...] # Reference model logprobs
messages: Optional[...] # OpenAI-format messages
inference_logprobs: Optional[...] # Inference logprobs
BaseEnvConfig Key Fields
| Field | Default | Description |
|---|---|---|
group_size |
4 | Responses grouped for scoring |
steps_per_eval |
100 | Steps between evaluations |
max_token_length |
2048 | Max token length for generations |
total_steps |
1000 | Total training steps |
use_wandb |
True | Enable wandb logging |
tokenizer_name |
DeepHermes-3 | Tokenizer for token encoding |
ensure_scores_are_not_same |
True | Skip groups with identical scores |
worker_timeout |
600 | Task timeout seconds |

Atropos Environment Statistics (82 environments analyzed)
- 95% implement setup, collect_trajectories, evaluate, get_next_item
- 76% override wandb_log
- 54% have custom config class
- Most use collect_trajectories (plural), not collect_trajectory (singular)
- Common reward patterns: LLM-judge (~40), regex-extract (~35), code-exec (~12)
