Sovereign backup of all Hermes Agent configuration and data. Excludes: secrets, auth tokens, sessions, caches, code (separate repo). Tracked: - config.yaml (model, fallback chain, toolsets, display prefs) - SOUL.md (Timmy personality charter) - memories/ (persistent MEMORY.md + USER.md) - skills/ (371 files — full skill library) - cron/jobs.json (scheduled tasks) - channel_directory.json (platform channels) - hooks/ (custom hooks)

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

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)
