description

Hivemind multi-harness integration specialist. Covers adding and auditing harness adapters across the six supported coding assistants (Claude Code, Codex, Cursor, Hermes, pi, OpenClaw), capability detection and auto-install (src/cli/install-*.ts), per-host wiring (hooks vs extension vs MCP vs AGENTS.md marker), the capture/recall hook lifecycle, the shared-core + per-harness-bundle build model, MCP server registration (hermes), contracted tools (openclaw), and keeping the tool/hook contract stable across hosts. Use when the user says "wire a new harness", "add a hook event", "register the MCP server in hermes", "audit a harness adapter", "the OpenClaw bundle fails ClawHub scan", "capability detection for install", or when harness-integration-worker-bee is invoked. Do NOT use for Deep Lake dataset schema (deeplake-dataset-stinger), embeddings runtime (embeddings-runtime-stinger), MCP protocol internals beyond registration (mcp-protocol-stinger), or CI/CD pipeline topology (ci-release-stinger).

harness-integration-stinger

The integration playbook for harness-integration-worker-bee. Encodes how Hivemind plugs into six coding assistants through one shared core (src/), per-agent installers (src/cli/install-*.ts), and per-agent build outputs (harnesses/<agent>/) - from a fresh adapter to a ClawHub-clean OpenClaw bundle.

Critical directives

These are the non-negotiables. Violating any of them is the most common cause of a broken harness adapter. See the relevant guide for code patterns.

1. Keep the tool and command contract identical across every host. hivemind_search/hivemind_read/hivemind_index (plus hivemind_goal_add/hivemind_kpi_add on OpenClaw) must have the same name, args, and return shape everywhere. A drift in one host silently breaks cross-harness recall. Source: research/external/2026-06-16-tool-contract.md.

2. Hooks must be fast and fail-open. Capture hooks run on the agent's critical path. Honor the per-event timeout (SessionStart 10s, PreToolUse 60s, capture 10-30s), dispatch heavy work async: true, and never let a hook crash block the host. Source: research/external/2026-06-16-hook-lifecycle.md.

3. Capability detection must be cheap and side-effect free. hivemind install auto-detects each assistant by probing for its home dir / binary (~/.claude/projects, ~/.codex, ~/.cursor, ~/.hermes, ~/.pi, OpenClaw). Detection runs on every install; it must not write files or spawn work. Source: research/external/2026-06-16-capability-detection.md.

4. Never hardcode bundle paths - resolve them per host. Claude Code forks node "${CLAUDE_PLUGIN_ROOT}/bundle/<entry>.js"; Cursor/Hermes use ~/.<host>/hivemind/bundle/. Use the host's own root variable so the marketplace plugin and local installs both resolve correctly. Source: research/external/2026-06-16-architecture-build.md.

5. The OpenClaw bundle must pass the ClawHub static scanner. ClawHub forbids bare spawn/execFileSync. Route subprocess access through createRequire-based indirection (see src/skillify/gate-runner.ts comments and scripts/audit-openclaw-bundle.mjs) or the bundle is rejected. Source: research/external/2026-06-16-openclaw-clawhub.md.

6. Register the MCP server only where the host supports it. Hermes wires the MCP server (src/mcp/server.ts) under mcp_servers.hivemind in ~/.hermes/config.yaml. Do not assume every host has an MCP transport - Claude Code and Cursor use hooks; pi/OpenClaw use native extensions. Source: research/external/2026-06-16-mcp-registration.md.

7. pi ships raw TypeScript; do not pre-compile it. harnesses/pi/extension-source/hivemind.ts is delivered as .ts and pi compiles it at load. Bundling or transpiling it in the installer breaks the load path. Source: research/external/2026-06-16-pi-extension.md.

Scope note

This stinger covers the integration surface: the six harness adapters, their wiring mechanisms (hooks, native extensions, MCP, AGENTS.md marker), capability detection, the build model, and the tool/hook contract. It does not cover the Deep Lake dataset schema, the embeddings runtime, retrieval ranking internals, or MCP wire-protocol details beyond registration - route those to the relevant stinger (deeplake-dataset-stinger, embeddings-runtime-stinger, retrieval-stinger, mcp-protocol-stinger).

Handoff map

• Deep Lake sessions/summaries table schema and the capture write path internals: route to deeplake-dataset-stinger.
• Embeddings model selection, batching, runtime cost: route to embeddings-runtime-stinger.
• MCP protocol internals (tool schemas, transport framing) beyond hermes registration: route to mcp-protocol-stinger.
• Bundling/esbuild pipeline topology and release CI: route to ci-release-stinger.
• Login device flow and token vault security audit: route to security-stinger.
