opchain

Tools

Token cost is the o200k count of the tools list JSON, including schemas, before any tool is called.

• list_skills

  List every opchain skill (id, displayName, description, phases, commands). Call this first to see the concept→ship pipeline.

• route

  Map a request or an /oc-* command to the skill that should handle it, with the entry phase. Use when you're unsure which skill fits.

• get_skill

  Return the full SKILL.md (the instructions) for one skill id. Load it, then follow it. Read get_orchestrator once before your first get_skill in a session.

• get_orchestrator

  Return the shared orchestrator protocol (welcome flow, pipeline map, active-chaining rules). Read once at the start of a session.

• create_checkpoint_session

  Create a private server-issued session for checkpoint storage. Retain the returned sessionId and use it with read_checkpoint/write_checkpoint; never invent or share one.

• read_checkpoint

  Read a skill's saved session checkpoint (where you left off). sessionId must be a private token returned by create_checkpoint_session.

• write_checkpoint

  Persist a skill's session checkpoint so progress survives across sessions. Stores the object as given (any JSON object up to 64 KiB); it does not validate it against the opchain checkpoint protocol, s
