The tools mostly map to distinct lifecycle phases: precheck before an action, observe after it, recall memory, checkpoint state snapshots/closure, handoff delegation, and plan task planning. Some boundary blur exists because checkpoint and recall both involve task state, and several tools bundle multiple sub-actions, but overall the purposes are separable.

All tools follow the same osiris.<single_lowercase_concept> pattern with no mixing of casing or verb styles. The convention is predictable and readable across the entire set.

Six tools is well-scoped for an agent governance/lifecycle server. Each tool corresponds to a meaningful phase or contract, and the count avoids both thinness and excessive surface area.

The set covers the core lifecycle: pre-action checks, observation, recall, checkpointing/closure, delegation handoff, and task planning. Minor gaps exist around explicit listing/inspection or cancellation operations, but agents can likely work around them through recall/status modes.
