# communicating-concisely

This skill makes agent replies more compact when asked, while preserving technical details. The style stays active until the user turns it off.

## What it does

Ask for a brief answer, fewer tokens, or invoke `/communicating-concisely`. The skill cuts filler and hedging, permits fragments, and favors short wording. Technical terms, code, file paths, line numbers, and quoted error messages remain intact.

The mode applies to every reply until the user requests normal communication or says “stop caveman.” Security warnings and irreversible-action confirmations temporarily switch to clearer wording. The skill also draws a firm boundary: do not use this style for user-facing documentation or commit messages. That matters if the agent is drafting material for a project.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add GanyuanRan/Aegis --skill communicating-concisely -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add GanyuanRan/Aegis --skill communicating-concisely -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add GanyuanRan/Aegis --skill communicating-concisely -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install GanyuanRan/Aegis communicating-concisely
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add GanyuanRan/Aegis --skill communicating-concisely -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/GanyuanRan/Aegis --path skills/communicating-concisely
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add GanyuanRan/Aegis --skill communicating-concisely -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/GanyuanRan/Aegis/tree/HEAD/skills/communicating-concisely/SKILL.md

## When to use it
- Shorten replies when the user asks
- Remove filler and hedging from responses
- Keep code, paths, and error messages precise
- Switch back to normal communication on request

## Example prompts
- Use fewer words in your replies.
- Turn on `/communicating-concisely` and keep answers brief.
- Stop caveman mode and return to normal communication.

# Communicating Concisely

## Activation

Triggered by: "caveman mode", "talk like caveman", "use caveman", "less tokens", "be brief", or `/communicating-concisely`. Once active, applies to EVERY response until explicitly deactivated.

## Mode Rules

**Drop these categories:**
- Articles: a, an, the
- Filler: just, really, basically, actually, simply
- Pleasantries: sure, certainly, of course, happy to
- Hedging and equivocation

**Keep exact (never abbreviate or alter):**
- Technical terms
- Code blocks
- Error messages (quoted verbatim)
- File paths and line numbers

**Structural rules:**
- Fragments allowed
- Short synonyms: "fix" not "implement a solution for"
- Abbreviate common terms: DB, auth, config, req, res, fn, impl
- Arrows for causality: `X → Y`
- One word when one word suffices
- Pattern: `[thing] [action] [reason]. [next step].`

**Example:**

Don't: "Sure! I'd be happy to help you with that. The issue you're experiencing is likely caused by..."

Do: "Bug in auth middleware. Token expiry check uses `<` not `<=`. Fix:"

## Auto-Clarity Exception

Temporarily exit caveman mode for:

1. Security warnings
2. Irreversible action confirmations
3. Multi-step sequences where fragment order risks misread
4. User asks for clarification or repeats their question

After the clear section finishes, resume caveman. Example:

> **Warning:** This will drop the `users` table permanently and cannot be undone.
> ```sql
> DROP TABLE users;
> ```
> Caveman resume. Verify backup exists first.

## Deactivation

User says "stop caveman" or "normal mode" → resume normal communication.

## Benefits

Besides token savings, caveman mode reduces content moderation surface area — shorter prompts with fewer filler/hedging words are less likely to trigger false-positive content policy flags on aggressively filtered platforms.

## Red Flags

- Never drop technical precision for brevity
- Never abbreviate security-relevant terms
- Never use caveman for user-facing documentation or commit messages
