What it does

Integrate Harness is an agent skill from a5c-ai/babysitter. Use when adding a new agent harness (CLI-based coding agent) adapter to adapters. Covers capability audit, adapter scaffold, session parsing, auth detection, hooks/plugins wiring, tests, and docs.

Its SKILL.md is about 850 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Agent Workflows. It works with Model Context Protocol. The repository describes itself as: Babysitter enforces obedience on agentic workforces and enables them to manage extremely complex tasks and workflows through deterministic, hallucination-free self-orchestration. The licence is MIT.

Workflow steps

11 steps, taken from the first numbered list in SKILL.md.

Capability audit — read the harness's CLI docs. Fill in every AgentCapabilities field. Unknown? Set conservatively (false) and note in PR.
Create packages/adapters/src/-adapter.ts extending BaseAgentAdapter. Required: agent, displayName, cliCommand, minVersion, hostEnvSignals…
Session parsing — if the harness stores JSONL sessions, delegate to parseJsonlSessionFile; otherwise write a custom parser and unit-test…
Hooks — if the harness supports native hooks, override writeNativeHook and mirror into HookConfigManager. If not, rely on the base class's…
Plugins — if it supports MCP servers under mcpServers in its config JSON, flip supportsPlugins: true, add pluginFormats: ['mcp-server']…
Register — add to packages/adapters/src/index.ts exports and to the default registry in packages/core/src/client.ts (if applicable).
Tests — in packages/adapters/tests/-adapter.test.ts
CLI audit test — ensure packages/cli/tests/commands-audit.test.ts passes (it exercises every adapter via the built CLI).
File-size limit — each source file must stay under 400 effective lines (local/max-file-lines). Split helpers into sibling modules if…
Docs — add a row to the README capabilities matrix and a paragraph in docs/02-agents/.md.
Changeset — npm run changeset, pick minor (new adapter), summarize.

What it can do on your machine

Read from SKILL.md and the folder at commit feb68ab. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
- npm
- npx
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use npm and npx, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Integrate Harness loads about 846 tokens when it runs. Until then it costs about 54 tokens; SKILL.md has 348 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~54
When it runs · the whole SKILL.md, loaded when a task matches: ~846

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

name: integrate-harness
description: Use when adding a new agent harness (CLI-based coding agent) adapter to adapters. Covers capability audit, adapter scaffold, session parsing, auth detection, hooks/plugins wiring, tests, and docs.

integrate-harness

Goal: produce a production-quality XAdapter extends BaseAgentAdapter with full test coverage and documentation, matching the level of the existing 11 adapters (claude, codex, cursor, gemini, opencode, openclaw, copilot, hermes, pi, omp, adapters-remote).

Checklist

Capability audit — read the harness's CLI docs. Fill in every AgentCapabilities field. Unknown? Set conservatively (false) and note in PR.
Create packages/adapters/src/<name>-adapter.ts extending BaseAgentAdapter. Required: agent, displayName, cliCommand, minVersion, hostEnvSignals, capabilities, models[], defaultModelId, configSchema, buildSpawnArgs, parseEvent, detectAuth, getAuthGuidance, sessionDir, parseSessionFile, listSessionFiles, readConfig, writeConfig.
Session parsing — if the harness stores JSONL sessions, delegate to parseJsonlSessionFile; otherwise write a custom parser and unit-test each event shape.
Hooks — if the harness supports native hooks, override writeNativeHook and mirror into HookConfigManager. If not, rely on the base class's virtual hooks.
Plugins — if it supports MCP servers under mcpServers in its config JSON, flip supportsPlugins: true, add pluginFormats: ['mcp-server'], and delegate to mcp-plugins.ts (see cursor/gemini/opencode/openclaw for the pattern).
Register — add to packages/adapters/src/index.ts exports and to the default registry in packages/core/src/client.ts (if applicable).
Tests — in packages/adapters/tests/<name>-adapter.test.ts:
- capability shape
- buildSpawnArgs for a few representative RunOptions
- parseEvent for each JSONL type the harness emits
- detectAuth for authenticated + unauthenticated states
- session file parsing from a real fixture (redacted)
- If plugins: add the adapter to mcp-plugins-parity.test.ts.
CLI audit test — ensure packages/cli/tests/commands-audit.test.ts passes (it exercises every adapter via the built CLI).
File-size limit — each source file must stay under 400 effective lines (local/max-file-lines). Split helpers into sibling modules if you're close.
Docs — add a row to the README capabilities matrix and a paragraph in docs/02-agents/<name>.md.
Changeset — npm run changeset, pick minor (new adapter), summarize.

Verification

bash

npm run typecheck
npm run lint
npm test
npx vitest run packages/adapters/tests/<name>-adapter.test.ts

All existing tests must continue to pass — no regressions in commands-audit.

Common pitfalls

Forgetting to add the adapter to the default registry → commands-audit.test.ts won't exercise it.
JSONL parsers that assume a single event per line — some harnesses emit arrays.
Auth detection that reads env vars synchronously at construction time instead of detectAuth() — breaks testability.
buildSpawnArgs returning the string "undefined" for missing options — always gate with if (options.X != null).
Hook writers that overwrite rather than merge — use appendJsonHook or appendYamlHook.
