Description
Contract-driven multi-agent orchestration with ACP. Contract sync, webhook + dispatch-queue dual dispatch, cross-review, auto-retry, batch progress tracking.
Usage Guidance
This skill appears to be what it says — a repo-local CLI for coordinating generator/evaluator ACP sessions. Before installing or running it, consider the following:
- Run in a sandbox or non-production repository first. The workflow expects and documents automatic git add/commit/push actions by generators; if you run this in a repo with a configured remote, agents could push changes upstream. Prefer repos where automatic pushes are acceptable or disable automatic push in your workflow.
- Inspect prompt templates (packages/prompts/templates and renderRetryPrompt output) to ensure they don't instruct unapproved external actions. The generator prompts determine what the AI will do (including commands to run).
- Check your OpenClaw webhook configuration (nexum/config.json and ~/.openclaw/openclaw.json). Ensure webhook gatewayUrl and tokens point to endpoints you control; do not expose production webhook tokens unintentionally.
- The CLI reads/writes project files (AGENTS.md, nexum/*). Back up important state before first run.
- If you want to reduce blast radius, run the CLI with limited git credentials (or no remote), or avoid enabling autonomous agents that perform pushes.
If you want, I can point out the specific files and lines that implement git operations, webhook dispatch, and prompt rendering so you can review them in more detail.
Capability Assessment
Purpose & Capability
Name/description (contract-driven multi-agent orchestration) matches the repository contents (CLI, core, spawn, prompts, notify packages). The included commands, dispatch queue, webhook flow, and ACP runtime references are coherent with the stated purpose. No unrelated cloud credentials, binaries, or installs are requested.
Instruction Scope
SKILL.md + code instruct the agent/CLI to read and write project files (AGENTS.md, nexum/* runtime files), build prompts, and interact with git (read last commit; commit/push is part of the documented workflow). The skill expects the generator/evaluator to run git add/commit/push as part of normal flow (see COMMIT-CONVENTION and retry prompt). This is consistent with the orchestration purpose but elevates risk when run against sensitive repos because it encourages automatic commits and pushes.
Install Mechanism
No install spec in registry metadata; the SKILL.md expects Node >=20, pnpm, and openclaw. The repository is a pnpm monorepo with no remote download/install steps in the registry manifest. No arbitrary URL downloads or archive extraction were found.
Credentials
No required environment variables or credentials are declared. SKILL.md references OpenClaw webhook token locations (~/.openclaw/openclaw.json and OPENCLAW_HOOKS_TOKEN) and `nexum/config.json`, which is appropriate for webhook/notify functionality. There are no demands for unrelated secrets (AWS, SSH keys, cloud tokens) in the manifest. Still: the skill will operate using local git remotes if configured (git push is part of the workflow), so repository remotes and credentials can cause network activity.
Persistence & Privilege
always:false (normal). The CLI writes/updates files inside the project (AGENTS.md, nexum/ runtime files, generated prompt files) and manages a project-level session counter and dispatch-queue. It does not claim system-wide privileges or modify other skills. Because it encourages/assumes automatic git commits and pushes, it effectively has the ability to change remote repositories (subject to the user's git credentials).
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install opennexum - After installation, invoke the skill by name or use
/opennexum - Provide required inputs per the skill's parameter spec and get structured output

v2.1.0
v2.1.0: spawn.ts 重写(直接调 acpx)、通知模板全面重构(8种)、模型名标准化、commit message 带入通知、文档全面更新
v1.0.1
OpenNexum 1.0.1 brings a major refactor with TypeScript CLI and OpenClaw ACP integration.
- Migrated to TypeScript CLI for contract-driven agent orchestration.
- Expanded and reorganized documentation: new guides, contract templates, and lesson files.
- Switched from shell script tools to CLI commands: `nexum init`, `nexum spawn`, `nexum track`, `nexum eval`, `nexum complete`.
- Added Telegram notifications for session updates.
- Removed legacy shell scripts and redundant references to streamline usage.
- Upgraded file structure to support parallel ACP sessions and modern project setup.
v2.0.1
feat: auto-initialize project on first dispatch — no manual nexum-init.sh required for existing projects
v2.0.0
Phase 5: nexum-lint.sh (contract + project structure checks), pre-commit lint gate, TF-IDF dedup, nexum-revert --force + downstream escalation. Fix: nexum-revert.sh cancelled status write.
v1.3.0
Phase 4: cc-writer support, creative/task contract types, score-based eval, dispatch routing by contract.type
v1.2.1
Fix: harvest.sh AGENTS.md git commit, dispatch-gardener.sh, e2e screenshot TASK_ID injection
v1.2.0
Phase 3: harvest pipeline — lesson dedup, conflict detection, AGENTS.md auto-update, gardener prompt, on-complete batch trigger
v1.1.0
Phase 2: Playwright e2e eval, integration test eval, composite eval strategy
v1.0.0
Initial release: Contract-driven multi-agent orchestration with generator/evaluator loop, event-driven crash recovery, and knowledge accumulation.
