## What it does

inline-plan-dev takes an existing implementation plan and carries it out one task at a time. Before work starts, it checks the goal, acceptance criteria, repository state, assumptions, and current `HEAD`. Before each task, it revisits the referenced files, symbols, dependencies, and effects of earlier work. When the repository has changed, it adjusts the implementation details while keeping the intended outcome.

The skill runs verification at a depth matched to the risk, checks the affected scope, and updates task status in the plan file. Test, lint, typecheck, and implementation failures are investigated and fixed before execution continues. This workflow stays in the current agent session and does not dispatch subagents.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add sentimony/skills --skill inline-plan-dev -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add sentimony/skills --skill inline-plan-dev -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add sentimony/skills --skill inline-plan-dev -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install sentimony/skills inline-plan-dev
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add sentimony/skills --skill inline-plan-dev -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/sentimony/skills --path plugins/devflow/skills/inline-plan-dev
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add sentimony/skills --skill inline-plan-dev -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/sentimony/skills/tree/HEAD/plugins/devflow/skills/inline-plan-dev/SKILL.md

## When to use it
- execute an existing implementation plan
- resume interrupted task execution
- reconcile a plan with repository changes
- update task status as work progresses
- verify changes at the right depth

## Example prompts
- Execute the existing implementation plan in this session, one task at a time.
- Resume the interrupted plan, inspect the current `HEAD`, and update its task statuses.
- Check the next task against the repository, implement it inline, and run the appropriate verification.

# Inline Plan Development

## When to use and responsibility

Apply this skill when an implementation plan exists and the current agent executes it in
this session, task by task. The plan may come from `plan-crafting`, from another tool, or
from the user by hand. Resuming an execution that was interrupted enters here as well.

```text
PRESERVE PLAN INTENT, ACCEPTANCE CRITERIA AND SCOPE;
RECONCILE IMPLEMENTATION DETAILS WITH CURRENT REPOSITORY REALITY.
```

```text
An engineering problem is work, not a blocker.
```

Input: an existing plan, the current repository, and the user's authority over scope.
Output: the plan executed, its file updated to reflect real progress, and fresh evidence
handed to the completion owner.

Non-goals: this skill does not write plans, does not create `.sdd/` or any other runtime
state directory, does not dispatch implementer subagents, does not run reviewer agent
loops, does not perform model routing, does not create worktrees, does not run parallel
waves, and does not merge or clean up branches. Route each to its owner in section 9.

### Execution-mode contract

Once the user chose inline execution, execution stays inline. The availability of
subagents on this platform is not a reason to switch, and a silent transition to
orchestration is a contract violation of this skill.

When a task genuinely is unreasonable to execute inline, say so, name
`subagent-plan-dev` explicitly, give the reason, and let the user decide. Continue inline
until they answer.

## 1. Review the plan before the first task

Make one cheap pass over the whole plan:

1. extract the goal and the per-task acceptance criteria;
2. inspect repository reality for the files and symbols the plan names most often;
3. list the assumptions the plan rests on;
4. mark which tasks are high risk under the list in section 5;
5. once the execution workspace is chosen and before the first task edit, resolve the
   starting `HEAD` to a full SHA and record it as `BASE_SHA` in the execution record
   (section 10), together with the repository root and the paths that were already dirty.

Keep the pass proportional. Reading the whole repository is out of scope: the pass reads
the plan and samples what the plan points at. Raise a contradiction in plan intent now,
before work starts, rather than halfway through.

## 2. Reconcile the plan with current reality

A plan is written at one moment and executed at another. Separate three things:

| Term | Meaning |
| --- | --- |
| `PLAN INTENT` | which outcome is required |
| `PLAN APPROACH` | how the plan expected to reach it |
| `CURRENT REALITY` | how the repository looks now |
