Included Skills7

dispatch-governanceskills/dispatch-governance/SKILL.md

Partial Skill: invoke by name only — the Legate's routing brain — picks and executes a dispatch strategy for a role intent. Loaded in-session by the legate gateway, and by the headless-legate agent headless. Not triggered by users directly.

init-cyberlegionskills/init-cyberlegion/SKILL.md

Use this skill to set up or onboard cyberlegion in this session or repo — probe the environment, register the mail-surfacing hook, (in a root session, on your yes) allow the cyberlegion CLI in Claude Code's permissions, and bind this pane as the durable legate owner inbox. Triggers: 'set up cyberlegion', 'onboard the legion', 'register the cyberlegion surfacing hook', 'make this pane my main legion inbox', 'get cyberlegion working in this repo'. Not for spawning/messaging/dispatching a peer (that is legate), reading or acking owner mail (that is manage-inbox), or unrelated init like a git repo, npm package, or commit discipline.

legateskills/legate/SKILL.md

Use this skill when you need to reach another agent session — send a message to a named peer or "the pane on the right", check your inbox, wait for a reply, spawn or close a peer session, or dispatch work to fulfill a role and get a verdict back.

manage-inboxskills/manage-inbox/SKILL.md

Use this skill when the user wants to check, read, or clear the owner mailbox — the durable inbox where headless and cron-started agents send their reports. Triggers: 'check my inbox', 'any reports for me', 'what did the agents send', 'read that report', 'ack that', 'mark it read', 'clear my owner inbox', answering a question an agent left in a report, or acting on a surfaced owner-mail doorbell. Not for creating or binding the owner identity (init-cyberlegion) or a session's own mail (legate).

relay-governanceskills/relay-governance/SKILL.md

Partial Skill: invoke by name only — the Legion's report/ask contract — how a headless agent returns a result or surfaces a question it cannot answer, and how a receiver triages a relayed steer by authority level, and when a decision relayed by its own owner on a turn in its own session is adoptable. Loaded by dispatch-governance and any headless agent. Not triggered by users directly.

session-adapter-governanceskills/session-adapter-governance/SKILL.md

Partial Skill: invoke by name only — the SessionAdapter conformance rule: a mutating op verifies its observable effect landed or fails loud, keyed on the op's effect class. Loaded by CRs and producers touching adapter operations. Not triggered by users directly.

subagent-backend-governanceskills/subagent-backend-governance/SKILL.md

Partial Skill: invoke by name only — the caller-side procedure for the subagent dispatch path — the cold one-shot case and the owned-unit case. Loaded by dispatch-governance when it picks the subagent strategy. Not triggered by users directly.
