implement · posit-dev — Claude Code skill: what it does, how to install

Q: How to install implement in Claude Code?

Run `npx skills add posit-dev/skills --skill implement -a claude-code`.

Q: Can you change the LLM model during execution?

Yes, pass the `--model` flag followed by `sonnet`, `haiku`, or `opus` when invoking the skill.

Coordinates the rollout of a plan file by splitting work across parallel subagents. It checks git branch status and monitors progress.

What implement does

The skill reads a plan file and picks an orchestration guide based on available tools. If the environment provides Agent, TaskCreate, TaskUpdate, and TaskList, it follows references/claude-code.md. When task and read_agent are present, it reads references/copilot-cli.md. Otherwise, it falls back to references/generic.md.

Subagents handle distinct tasks at the same time instead of waiting in line. Before any worker touches the code, the skill inspects the git branch state. An unexpected branch or uncommitted changes will halt the run right away.

You invoke it with the path to your plan document. You can also override the model by supplying the --model flag with sonnet, haiku, or opus.

What it helps with

delegate tasks from a plan file to parallel subagents
verify git branch status before applying changes
track implementation progress across plan milestones
switch execution instructions based on detected agent tools

Example prompts for the agent

/implement plans/my-plan.md
/implement plans/my-plan.md --model sonnet
/implement plans/feature.md --model opus

# Implementation Orchestrator

Plan file: `$path`

Read your instructions from the appropriate reference file before proceeding:

- If you have access to Agent, TaskCreate, TaskUpdate, TaskList tools: Read `references/claude-code.md`
- Else if you have access to task and read_agent tools: Read `references/copilot-cli.md`
- Otherwise: Read `references/generic.md`
