# reap

Shows how much of the context an agent loads goes unused: idle skills, MCP servers, subagents, hooks and always-loaded prose. Measured from real session transcripts.

## What it does

The skill shells out to `reap --agent` and asks you to paste the output verbatim. No reformatting, no reordering, no trimming, and no headings or tables of your own: the binary renders the whole report, closing attribution line included.

Only arguments starting with `-` get passed through; anything else is dropped, and the skill says so. The evidence window comes from `--days N` (30 by default), pricing from `--model <id>`. Want the full inventory instead of the top rows? Use `reap --json`. Whether the tool exists is decided by `command -v reap` alone — a copy found elsewhere on disk might be an older build, and quietly using it would mask a broken install.

When `reap` is missing, the skill prints a single block: a one-off run via `npx skillreaper`, plus permanent install options. The `--agent` flag requires version 0.5.0 or newer; on an older build it fails with `flag provided but not defined: -agent`, and that calls for an upgrade rather than a fresh install. The skill never prunes anything by itself — `reap prune` is interactive and aborts without a terminal. Ask for it explicitly and it will run `reap prune --yes` and mention `reap restore --all`.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add thousandflowers/skillreaper --skill reap -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add thousandflowers/skillreaper --skill reap -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add thousandflowers/skillreaper --skill reap -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**

2. **Platform CLI**
```bash
gemini skills install https://github.com/thousandflowers/skillreaper --path plugins/skillreaper/skills/reap
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add thousandflowers/skillreaper --skill reap -a opencode
```

### Claude.ai

**Claude.ai**

## When to use it
- figure out why the context window keeps filling up
- spot skills and MCP servers that never fire
- measure how many tokens the always-loaded prose costs
- decide which tools are safe to drop
- break context spend down by category

## Example prompts
- Run reap and paste the report as is
- Run reap over the last 14 days and price it with `--model`
- Give me the full inventory with `reap --json`

# skillreaper - context utilization report

Run `reap --agent`, then paste its output verbatim.

Do not reformat, re-order, summarise, truncate or re-align anything, and do not
add a heading or a table of your own: the binary already renders the report,
including its closing attribution line.

## Arguments

Append any `$ARGUMENTS` tokens that begin with `-`; ignore anything else and say
so. `--days N` sets the evidence window (default 30), `--model <id>` prices it.
For the full inventory rather than the top rows, use `reap --json`.

## If reap is not installed

Decide with `command -v reap` and nothing else - never an absolute path, never a
filesystem search: a copy found off `PATH` may be an older build, and silently
using it hides a broken install.

If that fails, print exactly this and nothing else:

> `reap` is not installed. Run it once without installing anything:
>
> ```bash
> npx skillreaper
> ```
>
> Or install it permanently:
>
> ```bash
> brew install thousandflowers/tap/skillreaper
> ```
>
> ```bash
> go install github.com/thousandflowers/skillreaper/cmd/reap@latest
> ```

## If reap is too old

`--agent` needs reap ≥ 0.5.0. If it exits with
`flag provided but not defined: -agent`, say the installed build is too old and
give `brew upgrade skillreaper` (npm: `npm install -g skillreaper@latest`) - an
upgrade, never the install block above, which they have already done.

## Pruning

Never prune on your own initiative. `reap prune` is interactive and aborts when
it has no terminal, so calling it from here does nothing anyway.

If the user explicitly asks in this turn: get an unambiguous yes, run
`reap prune --yes`, and remind them of `reap restore --all`. If the request is
at all ambiguous, hand them the plain `reap prune` command instead.

For the per-category breakdown, point them at `/skillreaper:gap`.
