Use when detecting and guardrailing against premature completion claims — verifying that subagent "done" assertions are backed by fresh runtime evidence, enforcing dual-signal completion protocol (doer + verifier must agree), and catching hollow "it works" claims that skip verification. Triggers on: "verify completion", "completion detection", "dual-signal", "premature completion", "evidence before claims", "hollow done", "fake done", "completion guardrail", "verify before complete", "block completion until verified", "done but not verified", "did it actually work", "completion verification", "dual-signal completion", "two-agent completion", "fresh evidence requirement". NOT for loop mechanics (iterative-loop), delegation patterns (subagent-delegation-patterns), or quality gate triad orchestration (quality-gate-orchestration).
Use when making cross-cutting changes, cross-pane modifications, framework migrations, or breaking changes that span multiple layers or frameworks (GSD, BMAD, Hivemind, or other). Triggers on: "cross-cutting change", "cross-pane change", "multi-layer change", "framework migration", "breaking change across frameworks", "change impact analysis", "cross-framework change", "multi-pane impact", "test-first change ordering", "dependency ordering across layers", "consumer impact tracing", "interface-first change", "ordered change management". NOT for single-layer changes, single-framework refactors, or cosmetic edits. Framework-agnostic — works across GSD, BMAD, Hivemind, or any project governance framework.
Evaluates whether implementation evidence is sufficient to pass quality gates. Enforces an evidence hierarchy from live runtime proof (L1) down to documentation summaries (L5), and refuses gate passage when evidence is missing, mocked where integration is claimed, or insufficient for the gate type. Use during code review gates, phase audits, milestone verification, integration checks, and deployment readiness. Activates after gate-spec-compliance clears spec alignment — this is the terminal gate in the triad (lifecycle → spec → evidence). Triggers: "evidence check", "gate evidence", "verify runtime proof", "evidence truth", "is there proof this works", "evidence hierarchy", "gate truth", "runtime evidence", "integration evidence", "mock-only detection", "completion honesty", "gate passed", "gate failed". Terminal skill in the quality gate triad — if evidence PASSES, all 3 gates clear.
Internal quality gate that evaluates whether Hivemind harness implementations correctly participate in the runtime lifecycle — covering 9-surface mutation authority, CQRS boundaries, actor hierarchy, event-driven wiring, classification fit (src/ vs .opencode/ vs .hivemind/), and OpenCode SDK surface compliance. Synthesized from .planning/codebase/ARCHITECTURE.md (9-surface authority table) and ingested @opencode-ai/plugin SDK v1.14.44 from anomalyco/opencode (tool(), hook() signatures). Use when performing a lifecycle gate check, auditing harness module integration, verifying CQRS boundary compliance, checking delegation hierarchy constraints, evaluating tool/hook registration correctness, running a harness quality gate, validating plugin composition integrity, or running phase audit on src/ modules. Activates during code review of src/ files, phase audit, milestone verification, integration check, and deployment readiness workflows.
Spec compliance gate performing bidirectional traceability, gap detection (4 types), EARS acceptance criteria validation, and anti-pattern scanning. Use during code review gates, phase audits, milestone verification, and deployment readiness. Middle gate in the quality triad (lifecycle → spec → evidence). Routes to gate-evidence-truth on PASS; STOPS with gap report on FAIL. Includes remediation routing to hm-spec-driven-authoring, hm-test-driven-execution, and hm-debug for fix workflows. Triggers on: "spec compliance", "verify against spec", "gap analysis", "compliance gate", "phase audit gate", "acceptance criteria check", "spec-to-code", "deployment readiness", "triad gate", "spec gate middle", "quality triad".
Detects and fixes drift between AGENTS.md documentation and actual codebase state. Scans source files and .opencode/ directories, compares claims against reality, produces a structured drift report, then applies targeted edits. Triggers on: 'sync agents md', 'update AGENTS.md', 'fix agents md drift', 'AGENTS.md out of date', 'check agent instruction drift'. NOT for generic documentation writing or README refreshes.
Enforce pre-delegation authorization gates before agent dispatch. Use when setting up checkpoint gates, defining capability matrices, validating agent permissions, or approving a handoff boundary. NOT for orchestration execution, direct implementation, or generic task planning.
Routes requests about OpenCode meta-concepts (skills, agents, commands, tools) to specialist authors. Classifies intent, navigates step-by-step, reports back. Use when creating, auditing, stacking, or configuring any OpenCode meta-concept. Triggers on: 'create a skill', 'audit this skill', 'build an agent', 'set up a command', 'stack skills', 'configure OpenCode', 'fix skill trigger', '/hf-create', '/hf-audit', '/hf-stack'.
