From fulcrum
Only chief_of_staff may call invoke_team. Non-CoS roles escalate instead of attempting.
npx claudepluginhub moabualruz/fulcrum --plugin fulcrumThis skill uses the workspace's default tool permissions.
Policy invariant `only_l1_invokes_teams` denies `fulcrum action exec invoke_team` from any role other than `chief_of_staff`. Call rejected with clear error before reaching control plane. Don't attempt.

Migrates code, prompts, and API calls from Claude Sonnet 4.0/4.5 or Opus 4.1 to Opus 4.5, updating model strings on Anthropic, AWS, GCP, Azure platforms.
Automates semantic versioning and release workflow for Claude Code plugins: bumps versions in package.json, marketplace.json, plugin.json; verifies builds; creates git tags, GitHub releases, changelogs.

Team invocation spans multiple L2 roles, consumes multiple WIP slots, coordinates artifacts across workers. That fan-out = L1 orchestration. Letting any L2 do it = single specialist reshapes task board without visibility.
L2 role (software_engineer, code_reviewer, tech_lead, integration_worker, etc.) with work that genuinely needs team:
fulcrum action exec block_agent_run on current run with clear reason:
chief_of_staff in build_cos_context. CoS can invoke_team on your behalf.Need team: software_engineer + code_reviewer + security_reviewer.
Can implement auth middleware but change touches session storage
(packages/core/src/session) — security review I can't perform from
my role. Success = middleware merged with both reviews passing + no
new CVE surface.
software_engineer just called invoke_team → call failed. block_agent_run with team request.chief_of_staff called Write/Edit to avoid invoking team → different violation. See chief-of-staff-response-format.reason → CoS has nothing to act on. Write full context up front.See also: chief-of-staff-response-format, block-when-stuck.
