Implement planned work by fanning out parallel subagents on isolated worktrees — TDD at pre-agreed seams, per-slice nv-park-and-review, merge back, full suite once at the end.

  • Tasks that involve Git worktrees
  • SKILL.md covers Workflow, Commands (Novu), Guardrails and Related skills
  • Calls git, pnpm and npx

What it does

Nv Implement is an agent skill from novuhq/novu. Implement planned work by fanning out parallel subagents on isolated worktrees — TDD at pre-agreed seams, per-slice nv-park-and-review, merge back, full suite once at the end.

Its SKILL.md is about 1.7k 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 Testing & QA, covering Git worktrees, Subagents and Test-driven development. The repository describes itself as: The open-source communication infrastructure for agents and products.

When your agent uses it

  • Tasks that involve Git worktrees
  • Tasks that involve Subagents
  • Tasks that involve Test-driven development

Example prompts

  • “/nv-implement”

Requirements

  • Node.js

Workflow steps

6 steps, taken from the step headings in SKILL.md.

  1. Cut the work into seams
  2. Resolve feature branch + one worktree per seam
  3. Fan out subagents
  4. Merge slices back into the feature branch
  5. Integration pass
  6. Full suite once + teardown

What it can do on your machine

Read from SKILL.md and the folder at commit 5536391. 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:

    • git
    • pnpm
    • npx

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use git, pnpm 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

Nv Implement loads about 1.7k tokens when it runs. Until then it costs about 47 tokens; SKILL.md has 768 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~47
When it runs · the whole SKILL.md, loaded when a task matches
~1.7k

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.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 768 words (~1,700 tokens).

“Implement the work described (plan file, spec, or ticket) as vertical slices, one subagent per slice, each on its own worktree. Use /tdd where possible, at pre-agreed seams. Run typechecking regularly, single test files regularly, and the full test suite…”
