# implement_plan

Takes an approved plan from thoughts/shared/plans/, works through its phases one by one and checks each against the plan's success criteria. Handy once the design is settled and code is next.

## What it does

The skill reads the whole plan, plus the original ticket and every file the plan points to, then builds a todo list. Then it moves phase by phase: makes the changes, runs the checks the plan names (often `make check test`), fixes what breaks and ticks items off inside the plan file itself.

Two execution modes exist. For three tasks or fewer the skill does the work directly in the main conversation. From four tasks up it suggests agent orchestration: a thin orchestrator hands each task to a subagent, which does its part and writes a handoff to disk. That handoff survives context compaction, so a long implementation does not fall apart. Orchestration expects the `implement_task` skill at `.claude/skills/implement_task/SKILL.md` and a `thoughts/handoffs/<session-name>` directory. Before any editing the skill runs `/premortem deep <plan-path>`; high-severity risks block progress until they are accepted or mitigated. The premortem is skipped when the plan already carries a risks section or `--skip-premortem` is passed.

After automated checks pass for a phase, the skill pauses for manual testing. Manual-testing items stay unchecked until you confirm them. To run several phases without pauses you have to list them explicitly; otherwise it does one. When the codebase no longer matches the plan, the skill stops and reports the mismatch instead of guessing.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add parcadei/Continuous-Claude-v3 --skill implement_plan -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/implement_plan/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/implement_plan/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add parcadei/Continuous-Claude-v3 --skill implement_plan -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/implement_plan/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add parcadei/Continuous-Claude-v3 --skill implement_plan -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/implement_plan/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install parcadei/Continuous-Claude-v3 implement_plan
```

2. **Manually: put the files in place**
- File: `.github/skills/implement_plan/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add parcadei/Continuous-Claude-v3 --skill implement_plan -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/parcadei/Continuous-Claude-v3 --path .claude/skills/implement_plan
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/implement_plan/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add parcadei/Continuous-Claude-v3 --skill implement_plan -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/parcadei/Continuous-Claude-v3/tree/HEAD/.claude/skills/implement_plan/SKILL.md

## When to use it
- Work through an approved plan phase by phase without dropping items
- Run checks after each phase and repair failures before moving on
- Keep a long implementation on track with handoff files on disk
- Catch where the plan and the current code disagree and stop there
- Surface plan risks before the first edit

## Example prompts
- Implement the plan at `thoughts/shared/plans/auth-refactor.md`
- Take `thoughts/shared/plans/payments.md` and run every phase in sequence
- Use agent orchestration for `thoughts/shared/plans/migration.md` — four tasks, and context matters

# Implement Plan

You are tasked with implementing an approved technical plan from `thoughts/shared/plans/`. These plans contain phases with specific changes and success criteria.

## Execution Modes

You have two execution modes:

### Mode 1: Direct Implementation (Default)
For small plans (3 or fewer tasks) or when user requests direct implementation.
- You implement each phase yourself
- Context accumulates in main conversation
- Use this for quick, focused implementations

### Mode 2: Agent Orchestration (Recommended for larger plans)
For plans with 4+ tasks or when context preservation is critical.
- You act as a thin orchestrator
- Agents execute each task and create handoffs
- Compaction-resistant: handoffs persist even if context compacts
- Use this for multi-phase implementations

**To use agent orchestration mode**, say: "I'll use agent orchestration for this plan" and follow the Agent Orchestration section below.

## Getting Started

When given a plan path:
- Read the plan completely and check for any existing checkmarks (- [x])
- Read the original ticket and all files mentioned in the plan
- **Read files fully** - never use limit/offset parameters, you need complete context
- Think deeply about how the pieces fit together
- Create a todo list to track your progress

### Pre-Implementation Risk Check

Before starting implementation, run a deep pre-mortem:

```
/premortem deep <plan-path>
```

This analyzes the plan against comprehensive checklists:
- Technical risks (scalability, dependencies, data, security)
- Integration risks (breaking changes, migration, rollback)
- Process risks (unclear requirements, stakeholder input)
- Testing risks (coverage gaps, load testing needs)

**If HIGH severity risks are identified:**
- The premortem will block via AskUserQuestion
- User must: accept risks explicitly, add mitigations, or research solutions
- If mitigations are added, update the plan before proceeding

**Skip premortem if:**
