harness-engineering
An agent skill by muratcankoylan, from muratcankoylan/Agent-Skills-for-Context-Engineering. Tags: automation, debugging, developer-tools, devops, strategy.
What it does
This skill should be used when designing autonomous agent harnesses: research loops, evaluation scaffolds, locked and editable surfaces, durable logs, novelty gates, pruning, rollback, PR preparation, and human approval boundaries.
Install
With the skills CLI, which installs into Claude Code, Codex, Cursor and other agents:
npx skills add muratcankoylan/Agent-Skills-for-Context-Engineering --skill harness-engineeringOr copy the skill folder into Claude Code's skills directory by hand (~/.claude/skills for every project, or .claude/skills inside one):
git clone --depth 1 https://github.com/muratcankoylan/Agent-Skills-for-Context-Engineering
cp -r Agent-Skills-for-Context-Engineering/skills/harness-engineering ~/.claude/skills/harness-engineeringSafety box score
Grade A, minimal risk: 4 of 100 risk points, rated 2026-10-19. The grade rates what the skill and its scripts can reach on the machine of whoever installs it, across eight categories from shell execution to secrets access. How the score works.
This is a documentation-only skill for designing autonomous agent harnesses: feedback loops, durable logs, rollback, pruning, and PR preparation. It does not ship executable code or data exfiltration paths, but it does describe broader agent autonomy, so the main risk is using it to build long-running workflows that act without enough human oversight.
| Category | Level | Why |
|---|---|---|
| Code & shell execution | 0 (none) | `SKILL.md` is prose only; there are no shell commands, scripts, or code-evaluation steps to run. |
| Network access | 0 (none) | No download, upload, API-call, or remote-host interaction commands are present in the skill text. |
| Filesystem reach | 0 (none) | The file only describes conceptual surfaces like logs and drafts; it does not read, write, or delete real paths outside the repo. |
| Secrets & credentials | 0 (none) | There is no handling of tokens, passwords, keychains, `.env` files, or login material. |
| Privilege & persistence | 0 (none) | Nothing in the skill requests sudo, global installs, services, schedulers, or OS/shell configuration changes. |
| Instruction hijack surface | 0 (none) | The text does not tell the agent to ignore instructions, skip confirmations, or follow external content; it explicitly says merges/deploys/pushes need human approval. |
| Irreversible actions | 1 (low) | Its purpose is to design autonomous research/experiment loops and PR-producing/background agents, but governance is bounded by statements like "They should not merge, deploy, or push without human approval." |
| Transparency | 0 (none) | The skill is plain Markdown with no binaries, encoded payloads, or runtime-downloaded code. |
Before installing
- Read `SKILL.md` and confirm you want autonomy-oriented harness guidance, not just evaluation docs.
- Check that your workflow keeps merge/deploy/push actions human-approved.
- Make sure any durable logs or scratch files it inspires stay inside an expected workspace and do not touch secrets.
