What it does
Task Execution is an agent skill from simple-agent-lab/RSIHub. Solve repository tasks by inspecting first, making focused edits, and verifying the result.
Its SKILL.md is about 210 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It works with Python. The repository describes itself as: A research framework for principled agent self-improvement under frozen evaluators and declared mutation boundaries, recording verifiable lineage to make it reproducible and… The licence is Apache-2.0.
Example prompts
- “/task-execution”
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- Read the task instruction and inspect the relevant repository files.
- Form a concrete hypothesis before editing.
- Make the smallest coherent change that solves the task.
- Run focused checks, then broaden verification when the change has shared impact.
- Leave generated artifacts and unrelated files untouched.
What it can do on your machine
Read from SKILL.md and the folder at commit 64491da. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Task Execution loads about 212 tokens when it runs. Until then it costs about 27 tokens; SKILL.md has 111 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Task Execution
- Read the task instruction and inspect the relevant repository files.
- Form a concrete hypothesis before editing. If an execution deadline is supplied, check remaining time before a long operation and when changing approach. Reserve time for a usable result and its final verification; choose probes and tool waits that fit what remains. A shorter run is not success if required work is missing. Do not invent a deadline when the runtime reports that it is unavailable.
- Make the smallest coherent change that solves the task.
- Run focused checks, then broaden verification when the change has shared impact.

How do I install Task Execution in Claude Code?
Run `npx skills add simple-agent-lab/RSIHub --skill task-execution -a claude-code`. Or copy the skill folder (seeds/codex/skills/task-execution in simple-agent-lab/RSIHub) into .claude/skills/task-execution in your project. Claude Code loads it when a task matches its description.
How do I install Task Execution in Codex?
Run `npx skills add simple-agent-lab/RSIHub --skill task-execution -a codex`. Or copy the skill folder (seeds/codex/skills/task-execution in simple-agent-lab/RSIHub) into .agents/skills/task-execution in your project. Codex loads it when a task matches its description.
Can I use Task Execution in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add simple-agent-lab/RSIHub --skill task-execution -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/task-execution, .gemini/skills/task-execution, .github/skills/task-execution and .opencode/skills/task-execution in your project.
What does Task Execution need to run?
SKILL.md names no scripts, command-line tools or credentials: Task Execution is instructions for the agent only.
Does Task Execution access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is Task Execution safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
What licence does Task Execution use?
Task Execution is published under the Apache-2.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
How many tokens does Task Execution use?
About 212 tokens (SKILL.md is roughly 848 characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
What are the alternatives to Task Execution?
