At a glance

The engineering loop - select, advance, distill, deliver - for running a work session on a project.

  • Tasks that involve Autonomous loops
  • SKILL.md covers Route by moment, Scope and neighbors and The stance
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Loop Engineering is an agent skill from telagod/code-abyss. The engineering loop - select, advance, distill, deliver - for running a work session on a project. Invoke when STARTING a session or picking the next thing to work on; sizing a unit of work or matching it to your model tier; running long/autonomously and deciding pace or when to stop; deciding where a learning should live (lesson vs memory vs project-level skill); or wrapping up a unit/session (commit, report, handoff note).

Its SKILL.md is about 530 tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files (for example `advance.md`, `deliver.md` and `distill.md`).

It sits in Agent Workflows, covering Autonomous loops. The repository describes itself as: Give your AI coding agent a personality. Composable persona + style + skills for Claude Code, Codex, Gemini CLI & OpenClaw. Ships Tech Persona Card v1.0 spec. The licence is MIT.

When your agent uses it

  • Tasks that involve Autonomous loops

Example prompts

  • “/loop-engineering”

What it can do on your machine

Read from SKILL.md and the folder at commit 2544577. 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 527 tokens when it runs. Until then it costs about 112 tokens; SKILL.md has 234 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~112
When it runs · the whole SKILL.md, loaded when a task matches
~527

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.

Loop — the engineering cycle: select, advance, distill, deliver

Rule content lives in the four files below; this SKILL.md only routes (doctrine/04-maintenance.md governs edits to this bundle too).

Route by moment

You are about to…Read (in this folder)
Start a session; choose the next unit; size it; decide who/which tier runs itselect.md
Push a unit forward; wonder if you're stalled; pace an unattended runadvance.md
Decide where a learning goes — lesson, memory, project-level skill, or nowheredistill.md
Claim a unit done; commit; report; end the sessiondeliver.md

A full pass is select.md → advance.md → distill.md → deliver.md, once per unit of work; re-enter at select.md §5 after each landing.

Scope and neighbors

This bundle is the outer cycle that sequences the others across a session and a project. Whether/how to delegate and judge (escalate, done-gate, ask-user) is doctrine; how to work a problem once inside a unit (investigate, design, execute, verify, write) is methods; domain judgment is the matching domain bundle. When this bundle and doctrine both fire, doctrine first — its three non-negotiables apply inside every phase of the loop.

The stance

A project advances as a sequence of landed loops, and compounds only if each loop distills. Progress is landed deliverables, not activity (advance.md §3); the next session's speed is this session's runway (deliver.md §4); and the institution grows one filed learning at a time (distill.md §1) — that is how weak sessions get strong.

Can I use Loop Engineering 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 telagod/code-abyss --skill loop-engineering -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/loop-engineering, .gemini/skills/loop-engineering, .github/skills/loop-engineering and .opencode/skills/loop-engineering in your project.

What does Loop Engineering need to run?

SKILL.md names no scripts, command-line tools or credentials: Loop Engineering is instructions for the agent only.

Does Loop Engineering access the network?
