nubos-pilot

AI-driven planning and execution tool for code projects. Installs into 14 host CLIs (Claude Code, Codex, Gemini, OpenCode, Cursor and ten more) as a set of Markdown workflows + subagents.

• No daemon. Every command runs as a short-lived node invocation.
• Markdown-first. Workflows and agents are plain .md files — the host reads them directly.
• Atomic per-task commits. One task(M<NNN>-S<NNN>-T<NNNN>): … commit per unit of work. /np:undo-task and /np:undo are mechanical reverts.
• Multi-runtime. One source tree, one install payload, fourteen supported host CLIs.

Install

cd your-project/
npx nubos-pilot                                 # interactive: pick runtime(s) + scope + model profile
npx nubos-pilot --agent claude                  # non-interactive single runtime
npx nubos-pilot --agents claude,codex,cursor    # multi-runtime install

Supported --agent values: claude, antigravity, augment, cline, codebuddy, codex, copilot, cursor, gemini, kilo, opencode, qwen, trae, windsurf. Other top-level subcommands: update, uninstall, doctor, install-hooks, uninstall-hooks, plus --dry-run.

This writes a self-contained payload under .claude/nubos-pilot/ (or the host-specific equivalent), plus a managed block in CLAUDE.md / AGENTS.md / GEMINI.md. Uninstall with npx nubos-pilot uninstall.

Project layout

Every nubos-pilot project lives under .nubos-pilot/:

.nubos-pilot/
  PROJECT.md                     # product truth (filled by /np:discuss-project)
  REQUIREMENTS.md                # requirement register
  roadmap.yaml                   # schema_version: 2
  STATE.md                       # cursor: current milestone + current task
  milestones/
    M001/
      M001-CONTEXT.md            # locked user decisions from /np:discuss-phase
      M001-ROADMAP.md            # slice list, execution order
      M001-META.json
      slices/
        S001/
          S001-ASSESSMENT.md
          S001-PLAN.md           # planner output: contains <task> blocks inline
          S001-RESEARCH.md       # optional, from /np:research-phase
          S001-SUMMARY.md
          S001-UAT.md            # acceptance criteria
          tasks/
            T0001/
              T0001-PLAN.md      # scaffolded from <task> blocks
              T0001-SUMMARY.md   # executor fills after commit
            T0002/...
  codebase/                      # module docs from /np:scan-codebase

Milestone = "phase" in user-facing commands. /np:plan-phase 1 plans milestone M001 entirely — all its slices and tasks. Slice = wave. All tasks inside one slice run in parallel; slices run serially. Task = one atomic commit.

Happy-path workflow

/np:new-project                  # scaffold PROJECT.md + M001 shell
/np:discuss-phase 1              # locked decisions → M001-CONTEXT.md
/np:research-phase 1             # optional — stack + pitfalls → M001-RESEARCH.md
/np:plan-phase 1                 # planner + plan-checker → S<NNN>-PLAN.md + task files
/np:execute-phase 1              # slice by slice; tasks parallel within each slice
/np:verify-work 1                # post-execution goal-backward verification
/np:validate-phase 1             # Nyquist coverage audit: COVERED / UNDER_SAMPLED / UNCOVERED
/np:add-tests 1                  # persist VERIFICATION Pass-cases as node:test UAT

Recovery commands

| Command | When to use | |---|---| | /np:reset-slice [<task-full-id>] | Execute crashed mid-task. Discards working-tree changes for files_modified, drops the checkpoint, clears STATE.current_task. No commit. | | /np:undo-task <M001-S001-T0001> | One committed task is wrong. git revert --no-edit <sha>, task frontmatter → pending. | | /np:undo <1 \| M001-S001> | Roll back an entire milestone or one slice. Newest-first revert; every affected task → pending. | | /np:pause-work · /np:resume-work | Explicit session handoff. | | /np:skip · /np:park · /np:unpark | Task lifecycle state. |

Task-ID schema

All task IDs are M<NNN>-S<NNN>-T<NNNN> (3/3/4 digits):

M001-S001-T0001    # milestone 1, slice 1, task 1
M002-S007-T0042    # milestone 2, slice 7, task 42

Task commits:

task(M001-S001-T0001): add login form
task(M001-S001-T0002): wire login handler

Agents

Fourteen spawnable subagents are installed into the host's agent directory (alongside three np-critic-* audit modules consumed by np-critic):

• np-planner (opus) — breaks a milestone into slices + tasks
• np-plan-checker (opus) — adversarial goal-backward review before execution
• np-architect (sonnet) — optional ADR-style decisions before planning
• np-researcher (sonnet) — milestone-level stack + pitfalls research
• np-researcher-reconciler (sonnet) — reconciles disagreements across researcher-swarm outputs
• np-sc-extractor (haiku) — derives observable Success Criteria from goal + CONTEXT
• np-codebase-documenter (sonnet) — maintains .nubos-pilot/codebase/ module docs
• np-executor (sonnet) — one task per spawn, one commit per task
• np-build-fixer (sonnet) — recovery patcher for executor verify failures (manual spawn)
• np-critic (sonnet) — Nubosloop critic; audits executor output across style, tests and acceptance
• np-verifier (sonnet) — post-execution Pass/Fail/Defer per success_criterion
• np-nyquist-auditor (haiku) — requirement test-coverage audit
• np-learnings-extractor (haiku) — headless continuous-learning observer; distils reusable {pattern, outcome} learnings from a session's turn-diff
• np-security-reviewer (sonnet) — OWASP-aligned read-only audit (manual spawn)

Every spawn runs with an explicit tier (haiku / sonnet / opus) resolved to a concrete model via np-tools.cjs resolve-model --profile <frontier|quality|balanced|budget|inherit>.

Model profile

Five profiles (frontier, quality, balanced, budget, inherit) map each tier (haiku / sonnet / opus) to a concrete model. Set at install time (Model-Profile? prompt) or in .nubos-pilot/config.json.

Requirements

• Node.js ≥22 (uses the built-in node:test runner)
• git on PATH for any execute/commit/undo operation

Commands

Run npx nubos-pilot help for the full list, or:

node np-tools.cjs help           # JSON: { commands: [ { name, category, description } ] }

Doctor

npx nubos-pilot doctor           # 12-check integrity scan
npx nubos-pilot doctor --fix     # auto-fix what's safely fixable

Checks: payload manifest integrity, version mismatch, hooks presence, codex-toml sanity, askuser runtime availability, codebase docs freshness, milestone/slice directory layout, the three Nubosloop checks (critics present, knowledge store, config), orphan temp files, and output schemas.

Development

npm test                         # all unit tests via node:test
node bin/check-workflows.cjs     # workflow linter

See CONTRIBUTING.md for setup, code conventions, ADR map and commit format.

Architecture Decisions

ADRs live in the VitePress at pilot.nubos.cloud/v1/adr/. The load-bearing ones for users and contributors:

| ADR | What it pins | |---|---| | 0004 | workflow.commit_artifacts controls whether .nubos-pilot/ is committed | | 0010 | Nubosloop — researcher → executor → critic-schwarm is mandatory in /np:execute-phase | | 0012 | Completeness doctrine (12 rules in templates/COMPLETENESS.md) | | 0013 | Learnings-store schema evolution | | 0017 | Strict output-schema enforcement | | 0019 | Plan-side trust layer (lib/plan-lint.cjs) |

Security

See SECURITY.md for the vulnerability disclosure policy and threat model.

Headless recursion guard

The in-session security review and continuous-learning hooks do their work in a headless claude -p subprocess. To stop that subprocess from re-firing the same hooks (which would cascade into an unbounded fork of claude/np-tools processes), nubos-pilot sets NUBOS_PILOT_HEADLESS=1 and a NUBOS_PILOT_HOOK_DEPTH counter on every headless spawn. The hooks no-op when NUBOS_PILOT_HEADLESS is set, spawn-headless refuses a nested or depth-exceeded spawn, and a per-agent lockfile under .nubos-pilot/run/ bounds concurrent headless runs to one per agent.

The guard is automatic — do not export NUBOS_PILOT_HEADLESS in your own shell, or the in-session hooks will silently do nothing. The depth cap is one level; override it with NUBOS_PILOT_MAX_HOOK_DEPTH only if you understand the recursion risk.
