Loop engineering runtime Grill + Monitor. An agent skill from akitaonrails/my-skills.

  • Works in 7 steps: Goal: "What are you trying to accomplish?" → Success criteria: "Describe how we know… → Success type: choose from test, build,… → …

What it does

Loop Engineering is an agent skill from akitaonrails/my-skills. Loop engineering runtime Grill + Monitor

Its SKILL.md is about 350 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Agent Workflows, covering Autonomous loops. The repository describes itself as: akitaonrails' personal skills (not tailored for general usage).

When your agent uses it

  • Tasks that involve Autonomous loops

Example prompts

  • “/loop-engineering”

Workflow steps

7 steps, taken from the first numbered list in SKILL.md.

  1. Goal: "What are you trying to accomplish?"
  2. Success criteria: "Describe how we know the loop succeeded."
  3. Success type: choose from test, build, lint, command, fileExists, oracle, observer, manual. For CLI steps provide successCommand; for file…
  4. Execute agent: fixer / designer / explorer / librarian
  5. Verify agent: oracle / observer / test
  6. Max attempts (default 3)
  7. Optional context files: which files or directories should be read before execution?

What it can do on your machine

Read from SKILL.md and the folder at commit 285ca82. 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

Loop Engineering loads about 353 tokens when it runs. Until then it costs about 14 tokens; SKILL.md has 163 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~14
When it runs · the whole SKILL.md, loaded when a task matches
~353

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.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 163 words (~353 tokens).
