Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00097 | $0.00519 |
| Opus 5 | $0.00048 | $0.00260 |
| Sonnet 5 | $0.00019 | $0.00104 |
| Haiku 4.5 | $0.00010 | $0.00052 |
Grade A, and why
loop-engineering scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
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 it | select.md |
| Push a unit forward; wonder if you're stalled; pace an unattended run | advance.md |
| Decide where a learning goes — lesson, memory, project-level skill, or nowhere | distill.md |
| Claim a unit done; commit; report; end the session | deliver.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.
What ships with it
4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

loop-engineering is a skill published in the GitHub repository telagod/code-abyss (240 stars, last pushed 1mo ago), licensed MIT. It adds 97 tokens to every session and 519 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
Other skills, from other repositories
article-writer
Multi-style article creation skill. Supports 5 writing styles (deep analysis, practical guide, story-driven, opinion, news brief), including complete workflow: material collection → outline → content → formatting. Activated when users mention "write article", "write post", "create", or "draft".
songwriting-and-ai-music
Songwriting craft, AI music generation prompts (Suno focus), parody/adaptation techniques, phonetic tricks, and lessons learned. These are tools and ideas, not rules. Break any of them when the art calls for it.
bilibili-helper
B站内容助手 - 视频标题描述优化、标签策略、封面设计建议、分区选择、评论互动.
office-pptx
Use when the user asks to create, inspect, verify, polish, or deliver PowerPoint .pptx decks, Google Slides-targeted deck artifacts, strategy narratives, operating reviews, pitch decks, teaching decks, section slides, bullet slides, or source-to-PPTX transformations.
excalidraw
Generate an Excalidraw whiteboard in Sean's hand-drawn video style (Excalifont, roughness 1, green signature, socials + watermark, source labels). Use whenever the user wants a whiteboard, diagram, teaching board, or "chart" for a video or the docs/whiteboards gallery — anything Sean will film with.
skill-management
Create, edit, and delete custom managed skills in the user's workspace. Use whenever the user wants to author a new skill from a description, scaffold a SKILL.md, or remove a skill they no longer need.
