RTK Setup — Persistent RTK Enforcement

This skill performs setup (persist RTK instructions) and ongoing enforcement (use rtk, propagate to subagents).

Phase 1: Detection (ALWAYS run first)

Run these checks before anything else:

rtk --version

• If rtk is NOT found → STOP. Tell the user: "RTK is not installed. Install it first: cargo install --git https://github.com/rtk-ai/rtk --locked". Do NOT proceed with setup.
• If rtk IS found → continue.

Check oh-my-opencode

ls ~/.config/opencode/oh-my-opencode.json 2>/dev/null

• If found → omo is installed. Note this for Phase 2.
• If not found → skip omo-specific steps.

Phase 2: Setup (persist to AGENTS.md)

Check BOTH of these files for the RTK managed block:

1. User-level: ~/.config/opencode/AGENTS.md
2. Project-level: ./AGENTS.md (current workspace)

For EACH file, check if <!-- RTK:START --> exists. If it does NOT exist, append the following managed block to the file (create the file if it doesn't exist). NEVER replace existing content — only append.

<!-- RTK:START -->
<!-- Managed block - do not edit manually. Updated by: rtk-setup skill -->

## RTK Token Optimizer

This project uses **RTK** (Rust Token Killer) to reduce LLM token consumption by 60-90%.

### Rules for ALL agents (including subagents)

**ALWAYS** prefix these commands with `rtk`:

| Command | Use instead |
|---------|-------------|
| `git status/diff/log/add/commit/push/pull` | `rtk git ...` |
| `ls`, `ls -la` | `rtk ls` |
| `cat file` | `rtk read file` |
| `grep pattern .` / `rg pattern` | `rtk grep pattern .` |
| `npm test` / `cargo test` / `pytest` | `rtk test <cmd>` |
| `npm run build` / `cargo build` | `rtk err <cmd>` |
| `gh pr list/view` | `rtk gh pr list/view` |
| `docker ps` | `rtk docker ps` |
| `eslint` / `tsc` | `rtk lint` / `rtk tsc` |

**Do NOT** prefix: `npx`, `npm install`, `pip install`, `node`, `python3`, heredocs, piped commands.

<!-- RTK:END -->

If oh-my-opencode is installed

After updating AGENTS.md files, check if the omo config at ~/.config/opencode/oh-my-opencode.json has prompt_append fields on agents. If it does, inform the user:

"omo is installed. For maximum coverage, you can add RTK instructions to agent prompt_append fields in oh-my-opencode.json. This ensures subagents always use rtk even when AGENTS.md is not loaded. Want me to do this?"

Only modify oh-my-opencode.json if the user explicitly confirms. If they confirm, append this line to the prompt_append of sisyphus-junior agent (the primary coder):

\n\nRTK: ALWAYS prefix shell commands with `rtk` when available (git, ls, grep, test, build). Example: `rtk git status` not `git status`.

Do NOT modify other agents' prompt_append unless asked.

Phase 3: Ongoing Enforcement (EVERY time this skill is loaded)

For the current agent

From this point forward in this session, you MUST:

1. Use rtk prefix for all supported shell commands (see table above)
2. Verify rtk is available before first use: rtk --version
3. If rtk is not available in the current environment, fall back to normal commands silently

For subagent delegation

When delegating ANY task that involves shell commands (via task(), delegate_task(), or any delegation mechanism), ALWAYS add this to the MUST DO section of the delegation prompt:

- Use `rtk` prefix for shell commands when available (git, ls, grep, test, build). Run `rtk --version` first to check. If not installed, use normal commands. Examples: `rtk git status`, `rtk ls`, `rtk grep pattern .`, `rtk test npm test`.

This is NON-NEGOTIABLE. Subagents do not read AGENTS.md, so RTK instructions MUST be passed explicitly in every delegation prompt.

Quick reference for subagent prompts

Copy-paste this one-liner into MUST DO sections:

Use rtk prefix for all shell commands (git, ls, grep, test, build, docker). Example: rtk git status not git status. If rtk is not found, use normal commands.
